FIELD OF THE INVENTION The invention herein relates to the field of digital network and communication transmission system, more particularly, it relates to an apparatus able to provide multimode internetworking connectivity over a plurality of disparate network systems, service providers, and internetworking environments, concurrently and a method thereof. BACKGROUND OF THE INVENTION

The advent of digital technology had led to the convergence of computing, networking, and high-bandwidth communication technologies to provide network connectivity for a multiplicity of integrated and interactive multimedia applications. Due to the development and demand of said multimedia applications, it is inevitable that network systems and infrastructures have to evolve from a myriad of discrete network systems into integration as well as hybridization of network systems and infrastructures, giving rise to network systems such as Multi-Protocol Label Switching (MPLS) enabled IP system. In the internetworking environment, the Internet is presently the only global internetworking environment. The Internet is built upon Internet Protocol (IP) suites of network protocol stacks. Using IP-based routers and MPLS switches systems, data is routed from source to destination endpoints. Currently, end-user would subscribe for Internet services from a single Internet

Service Provider (ISP) by having interconnection between the Subscriber Network Equipment (SNE) and the ISP network gateway equipment. To provide for connectivity, the ISPs utilize existing circuit-based telephony switches and/or cable television (TV) infrastructures through copper wire, optic fibre, and/or wireless means to provide transmission medium services for network connectivity.

As known by those who are well-versed in the field, said Subscriber Network Equipment (SNE) has an operating system serving as network access controller for said SNE. Said network access controller has relevant network protocol stacks to support connectionless network systems, such as internet Protocol (IP) as well as, to support Signaling System No. 7 (SS-7) network signaling and point-to-point connection, such as Point-To-Point Protocol (PPP).

Said SNE either works as a stand-alone or as a multiplexer able to provide network connectivity to a plurality of network-enabled User Premise Devices (UPD). Said SNE not only provides Local Area Network (LAN) based connectivity services for multi-connections and sessions of said plurality of User Datagram Protocols (UDP) at their premises, but also provides external network connectivity and access to the Internet.

With SNE, such as Digital Subscriber Line (xDSL), Asynchronous Transfer Mode (ATM), and the likes, its network controller utilizes call establishment and PPP protocols to establish connectivity from the subscriber premise to the Internet Service Provider (ISP) network gateway switches using telephony network infrastructure. The Asynchronous Transfer Mode/Long-Term Evolution (ATM/LTE) network systems provide connectivity on the telephony section of the network while the MPLS-enabled IP network interfaces, supporting several Permanent Virtual Circuits (PVC), provides connectivity among a plurality of MPLS-enabled IP network switches on the Internet network section.

For data communication over copper telephony lines, frequencies not used for analog voice services are utilized for data transmission through the use of multi-carrier band modem, such as xDSL. Said multi-carrier band modems utilized Frequency-Division Multiplexing (FDM) means and Discrete Multi-Tone (DMT) line code technology, to enable greater data service capacity by dividing the useful bandwidth into discrete and smaller frequency channels.

This multi-carrier band methodology is also utilized in wireless data communication from the carrier bandwidth spectrum. In addition, said multi-carrier band methodology had also evolved to incorporate not only the use of frequency and code-division multiplexing but also time-division multiplexing technology, as well.

With DMT implementation, all available data bandwidth for data transmission is allocated to two transmission channels, one for upload and the other for download. Said upload and download channels provide for connectivity between the SNE and the ISP network gateway. It is a common practice for most xDSL and wireless modems to allocate a pre-defined discrete range of frequencies for download channel while another pre-defined range of frequencies for upload channel. With adaptive rate-based DSL modem said allocation of predefined discrete range of frequencies had been eliminated and replaced with dynamic allocation of bandwidth frequencies.

During initialization of xDSL modems, the controller of the modem would test each of the carrier bands, known as "bin", to establish the signal-to-noise ratio (SNR) for each multi- carrier band frequency. The controller will then make a plan on how to exploit each of the bins through what was termed "bits per bin" allocation. Those bins that have a good SNR will be chosen to transmit signals with a greater number of possible encoded values in each main clock cycle. If the SNR of the bins changes, the DSL modem can alter the bits-per-bin allocations.

It should be noted that although prior art provide for the classification of Quality of Service (QoS), based upon SNR factor, for each carrier band, it did not have the ability to prioritize and differing QoS data service for a plurality network connectivity based upon said QoS classification. As known by those well-versed in the field, none of the prior art documents, including those which use adaptive allocation of bandwidth technology, teaches means to dynamically portion bandwidth of differing QoS classification to support multi- mode connectivity sessions to multiple service providers or internetworking environments.

It should also be noted that data network devices disclosed in prior art documents only provide the means for multiple UPD connectivity for uploading and downloading channels, from the subscribers to a single ISP network gateway source, for a single-mode internetworking service. None of the prior art documents teach the means to support multi- mode connectivity sessions having the ability to subscribe to multiple ISPs. In addition, said network connectivity from existing ISPs provides only to a shared-media and connectionless IP-based internetworking environment. Thus prior art documents are only able to provide a single-mode internetworking environment.

With the increase usage and knowledge gain about the Internet network technology, the inherent weakness of shared-media and connectionless internetworking environment, which is its security vulnerability at the network level, had became well-known. Concern regarding the Internet inherent security vulnerability would inevitably leads to the need to develop a more secure internetworking environment, from a network level perspective. From historic perspective, should one view the evolution of the telephony environment, one could gain insight to the possible evolution of the future multimedia internetworking environment. The first iteration of telephony environment is a party-line environment where there is no network switching capability. Calls were broadcast through the phone line to a collection of interconnected telephone sets, similarly to first iteration of shared-media data LAN network systems.

As usage for telecommunication increases along with the number of user sets, switching capability was implemented at the exchange level, initially using manual means which then advance to mechanical means. This gave rise to the second iteration of telephony network systems. Said second telephony comprises of a hybrid of switched and non-switched network topology, which in a sense, resemble the present MPLS-enabled IP based network system.

Privacy issue and requirement from end-users, as well as, advent of electronic means eventually led to the third iteration of telephony systems and environment, end-to- end connected-oriented and dedicated-media communication thorough initially circuit-based and later to virtual circuit-switching methods.

As known by those well-versed in the art, hybrid MPLS-enabled IP network system enables circuit-switching for IP technology. Whereas technologist are aware the network environment is more secure at the MPLS network system section due to the use of circuit- switching method, they also understood that the network security vulnerability could be exploited at the IP section of network and router.

This is due to the ability for malicious users to exploit IP connectionless/stateless and share-media scheme of communication for anonymous intrusive eavesdropping, and more importantly, the ability to insert malicious instructions or programs at the network-level. Thus, there is a need to elimination said area of vulnerability in order to enhance security in the network-level of the environment.

In short, there is a need for another internetworking system and environment which does not, in anyway, uses connectionless and shared-media network topology and methodology. Method for creating such internetworking environment was shown in Malaysia Patent No. MY-129914-A by C T Lee, coined as Virtual Dedicated-Media Internetworking (VDMl) environment.

As known by those skilled in the art, prior art neither have the ability subscribe to nor concurrently support more than one ISP not to mention the ability to provide subscribers to subscribe to disparate internetworking environments. Basically, present network devices are not able to concurrently support dedicated-media and connection-oriented internetworking environment, such as VDMl, along with the present shared-media Internet environment. In short, prior art documents are engineered in a way where they are neither able to concurrently support multiple ISPs nor multi-mode internetworking environment, at the subscriber level.

The present invention is design to able subscribers to subscribe for multimode connectivity to multiple ISP and Application Service Provider (ASP) for disparate internetworking environments. The present invention provides for a novel controller for network devices, having means to subscribe and allocate resources for connectivity to multiple ISP and ASP in a multimode internetworking environment, concurrently.

SUMMARY OF THE INVENTION

The ftrst principal objective of the present invention is to provide a system having the ability to concurrently subscribe for network connectivity sessions to disparate shared-media and dedicated-media internetworking environments for Internet, MPLS-enabled VPN, and Virtual Dedicated-Media Internetworking services.

The second principal objective of the present invention is to provide the methods for the ability to portion bandwidth allocated for said communication channels, for connections to a plurality of disparate network systems and environments, concurrently, from a network transceiver, using either multi-carrier bands or Virtual Connection Circuit (VCC) method.

The third principal objective of the present invention is to provide said transceiver's controller with network protocol stacks and access control procedures for the establishment of communication sessions not only for IP-based application services but also for VDMI- based applications services. The fourth principal objective of the present invention is to provide the method for dynamic allocation of carrier bands of spectrum and frequency based medium, as well as, for bandwidth allocation for VCC systems, to enable said transceiver to concurrently support connectivity sessions to plurality of network and application service providers in a plurality of internetworking environment.

The fifth principal objective of the present invention is to provide call establishment capability for the transceiver controller to communicate to public VCC network central controller and with the destination network gateway transceiver for the subscription and establishment for communication channels from said transceiver to said network gateways.

The sixth principal objective of the present invention is to provide end-users with concurrent connectivity to public and shared-media Internet services, MPLS-enabled IP Virtual Private Network (VPN) services, entirely connection-oriented sessions using end-to- end circuit-switching for VDMl-enabled internetworking services for discrete and hybrid types of application services, among disparate connection-oriented and connectionless network systems and environments for a myriad of applications.

DETAILED DESCRIPTION OF THE INVENTION

Fig. 1 illustrates the present global shared-media internetworking environment, the Internet, operating over a plurality of interconnected digital network systems topology. For fast Internet services, said global Internet backbone network system (11) utilizes MPLS- based circuit-switching capability for interconnecting a plurality of regional Internet Service Provider (ISPs) Internet systems (41), Multi-Protocol Label Switching (MPLS) based Virtual Private Networks (VPN) (40) and mobile networks (36).

As shown, the Subscriber Network Equipment (SNE) transceiver (44, 44a) functions either as a standalone or multiplexer, able to provide connectivity for a plurality of sub-net of User Premise Device (UPD) transceivers (18), through wired or wireless means. As illustrated, said SNE is only able to support a single connection to a single ISP (45) to provide connectivity for Internet (34) services.

Fig. 2 illustrated the ability of the present embodiment SNE transceivers (12, 12a) to subscribe, support, and manage multiple communication session in order to provide concurrent connectivity of public and shared-media Internet services (34), IP (Internet Protocol) based and associative addressing switching-enabled VPN services (35), hybrid network system connection sessions among disparate connection-oriented and connectionless network systems services (33), and end-to-end, connection-oriented, and circuit-switching connection sessions for Virtual Dedicated-Media Internetworking (VDMI) - based application services (32).

As shown, the SNE transceiver ( 2, 12a) could functions either as a standalone or a multiplexer, able to provide connectivity for a plurality of sub-net transceivers ( 8), through wired or wireless means, and is able to connect to a plurality of service provider networks and internetworking' services.

As depicted, those wireless transceivers ( 2a) are connected to mobile network (39) having associative addressing means, for routing and address resolution, while the Digital Subscriber Line (xDSL) transceivers (12) are connected to Digital Subscriber Line Access Multiplexer (DSLAM) ( 3) having Virtual Circuit Connection (VCC) multiplexing means and is subsequently connected to associative addressing switching-enabled shared-media network system (40) and/or VCC connection-oriented circuit-switching network system (30). Said xDSL and wireless transceivers (12, 12a) utilized a plurality of carrier bands for signal transmissions.

Fig. 2 and 3 illustrated the types of internetworking environment connectivity which present embodiment transceivers are able to support for further clarification. As shown, the connectivity topology type 34 is for subscription to shared-media internetworking environment, and the connectivity topology type 32 is for virtual dedicated-media internetworking environment (38). Also noted is the present embodiment ability to subscribe and support concurrent shared-media and virtual dedicate-media internetworking environment (38) which is the used of both types of topologies 34 and 32 or its equivalents.

Unlike the present embodiment, prior art transceivers and network switches are able to support and subscribe only to share-media internetworking environment (41), as illustrated in Fig. 4. Fig. 5 depicts the types of existing prior art internetworking environments, encompassed within a shared-media internetworking environment (41), which are IP router-based. Internet (49), MPLS-enabled Internet (1 1), and IP-based MPLS-enabled VPN (40) environments.

As illustrated in Fig. 6, the key components of SNE transceiver (12, 12a) are a programmable network data-link control means (21) and a programmable network access control means (20). Said network access control (20) is able to establish a plurality of transmission channels, through said data-link control (21), for receiving and transmitting of digital signal. Said network access control (20) is to manage the allocation of communication bandwidth or carrier bands to enable concurrent connectivity of a plurality of communication channels and sessions to a plurality of disparate internetworking systems and environment.

As shown, said network access control (20) comprises of a network connection protocol stack and signaling database module (22), and network connection management module (23). Said network connection management module (23) further comprises of a bandwidth resource database (27), a user network connection profile database (26) and a network connection database (28) component.

Said network connection signaling database module (22) containing a library of multiple network signaling and/or network access management procedural protocols (24). Said network access control (20) is able to subscribe for communication channel and session of connectionless and shared-media internetworking environment, and/or connection-oriented and VDMI environment by using the appropriate signaling protocols from said network connection signaling database (22).

Said network connection management module (23) further comprises of a LAN connectivity sub-module (25) and a Wide Area Network (WAN) connectivity sub-module (29). LAN connectivity sub-module (25) only manages communication sessions among a plurality of sub-nets, while said WAN connectivity sub-module (29) manages external communication connections and sessions among a plurality of Internet Service Providers (ISP) and Application Service Providers (ASP).

FIG. 7 illustrated the types of network protocol components and the connectivity states of prior arts, supported by network routers, switches, and transceivers for enabling present shared-media internetworking environments as depicted in Fig. 5. As illustrated, application-layer programs, such as File Transfer Protocol (FTP), Simple Mail Transfer Protocol (SMTP) and the likes, communicate in a finite-state machine or connection-oriented manner, as indicated by solid line (32). For media-based application, said application may subscribe to compression programs, such as Moving Picture Experts Group (MPEG), MPEG-1 or MPEG-2 Audio Layer III (MP3), and the likes. Said applications also utilize signaling protocol, such as Media Gateway Control Protocol (Megaco), Session Description Protocol/ Session Initiation Protocol (SDP/SIP), Real Time Streaming Protocol (RTSP) and the likes, for signaling, as well as for user transmission protocol means, such as Real-Time Transport Control Protocol (RTCP) and Real-Time Transport Protocol (RTP).

The latter protocols would then subscribe to transport-layer protocol such as Transmission Control Protocol (TCP), User Datagram Protocol (UDP) and Stream Control Transmission Protocol (SCTP). Whereas TCP and SCTP communication session are stately (connection-oriented), UDP is ^' not. Presently all those transport-layer protocols are engineered to be hot-wired to IP. Since IP network-layer protocol operates in a stateless communication session, thus the communication session after IP is connectionless, as indicated by the dotted lines (34).

To enable faster routing of IP packets, Multiple Protocol Label Switching (MPLS) was developed to enable IP switching through network switches instead of router. With MPLS, Permanent Virtual Circuits (PVCs) are programmed to enable circuit-switching of IP packets, creating a hybrid transmission media of packet-switching and circuit-switching communication means, as indicated by the dashed and dotted lines (33/35). Said IP packets, through IP routers or MPLS-enabled IP switches, are then routed through transmission medium supporting Data Link-layer network protocols such as gigabit-Ethernet, Asynchronous Transfer Mode Adaptation Layer 5 (AAL5/ATM), Synchronous Optical Network (SONET), and the likes.

From the SNE perspective, it should be noted that whereas SNE end-node switch, whether it utilizes optical or etectro-magnetic means for land-lines, is able to support multiservice provider communication channels, present xDSL devices are not able to do so. More importantly, as illustrated in Fig. 7, said communication channels and sessions only support a single internetworking environment, a shared-media internetworking, which is IP. It should be noted that the backbone network system for the back office of all present

VCC network central controller systems (31) operates using shared-media internetworking VPN, such as IP-enabled VPN. Thus, the vulnerable of VCC network central controller system (31) originated from the use of said IP system. FIG. 8 depicts the types of network protocol components and the connectivity states of the present embodiment, supported by network routers, switches, and transceivers to enable a multimode internetworking environment, as illustrated in Fig. 3. As depicted, prior discussed communication sessions and channels associated with prior arts are still applicable.

What is unique_ and different about the communication sessions and channels from prior art is the use of Media Adaptation Layer (MAL) higher-layer network protocol (80). Unlike prior transport-layer protocols which are hot-wired to IP network protocol, MAL (80) is not. Instead,- MAL (80) has a switching capability to subscribe to any transmission media or medium, depending upon what type of communication session been requested by the application-layer programs. This enables novel Internet-like application capability to operate natively on circuit-switching network systems.

For better understanding, let's view the differences from the perspective of secure transaction applications. Presently, using encryption and tunneling technology, secure transactions are conducted using firewall but still operates over packet-switching IP network environment. With MAL technology, it is possible to conduct secure transaction, using encryption and tunneling technology, over end-to-end connection-oriented and circuit- switching network topology, without having to traverse over any packet-switching networks at all, inclusive IP networks.

MAL higher-layer network protocol (80) has User Plane, Control Plane and Management Plane components. MAL's User Plane component enabled application-layer programs to interface and interconnect with it and subsequently to the subscribed lower- layer network protocol. MAL's Control Plane component control the interconnection and signaling with subscribed lower-layer network protocols while its Management Plane component governs and manages the types of interconnects be it with solely to connection- oriented and circuit-switched based transmission medium network protocols for VDMI environment, MPLS-enabled circuit-switching transmission medium with connectionless packet-switching IP transmission media environment, or a combination of both, concurrently.

As illustrated, MAL (80) has stately communication with application-layer programs, signaling protocols, and user transmission protocol means, as depicted by the bold solid lines (32). As shown, MAL (80) is able to support stateless communication session with ICMP and IP, as illustrated by the bold dotted lines (34), to IP transmission media. However, through PPP and Media Transfer Protocol (MTP), MAL is able to interface with stately transmission media systems such as Universal Mobile Telecommunications System/ Long-Term Evolution (UMTS/LTE), AAL5/ATM, and etc. In this situation, MAL (80) is able to still maintain stately communication sessions to the underlying transmission mediums, as illustrated by the bold solid lines (32).

Also illustrated, with MAL network protocol (80), it is possible for said VCC network central controller system (31 ) internetworking capability to be entirely established using circuit-switching backbone network system topology, inclusive its back office. This eliminates the network security vulnerability arising from IP system topology, due to the absent of shared-media internetworking implementation. Said VCC network central controller system (31) and its back office system are now able to operate entirely under end- to-end, connection-oriented and circuit-switching communication channels using PVC scheme.

For internetworking data communication, most present prior arts Subscriber Network Equipment or Customer Equipment (CE) were engineered in "client-mode design" rather than in "server-mode design" for WAN connectivity. This is due to the lack of call establishment listening port mechanism for WAN Connectivity sub-module. With client- mode design prior art equipment were engineered with a specific source connectivity function since there is only one internetworking environment, and from a single service provider whom provides said connectivity to said Internet environment. The exception is been the narrow Integrated Services Digital Network (ISDN's) CE equipment which could enable the establishment of client-mode connectivity to the most two service providers. For better understanding, below shall be described a prior art xDSL embodiment, using client- mode model for establishing connectivity for Internet.

Fig. 9 flowchart depicts the setting up procedures of prior art embodiment for single- mode connectivity to a single ISP service provider network gateway for shared-media IP environment using xDSL transceive On activation of prior art transceiver (44), step 101 , the program boot up the operating system for said xDSL in step (102) to serve as a network access controller (NAC), and load the appropriate network protocols and handshake/signaling protocols in step (103). Upon complete, transceiver (44) could now be able to proceed to establishing a connection listening port in process (104) and broadcast its availability for providing interconnection and internetworking to its sub-nets.

Transceiver (44) would then activate step ( 05) which is the process for testing each carrier/channel bands to determine the Signal Noise Ratio (SNR) for each carrier band, and periodically thereafter. Said NAC records the result of its test within NAC's along with the al!ocaied "bits per bin" for each channel band within its Bandwidth Resource database. Prior art Bandwidth Resource database usually contains fields for carrier band identification, SNR reading and "bit per bin" information only.

The transceiver (44) would then automatically proceed to step 106, and dial-up to DSLA device call establishment listing port using Point-to-Point Protocol (PPP) to procure a connection for data transmission from transceiver to said DSLAM and subsequently to its subscribe ISP's Internet or VPN gateway through step (108). Upon success of said procurement of connection to said DSLAM, transceiver (44) would then allocate all its carrier/channel bands for said allocated connection with said DSLAM to procure Internet service from said ISP and request and obtained an IP address for its usage. Upon completion, transceiver (44) could now proceed to step (109), which is the process to start accepting and process sub-nets Internet connection requests for connectivity to the Internet or MPLS-enabled IP-based VPN. Fig. 10 flowchart depicts present embodiment process for setting up call and connection establishment listening ports for multi-mode connectivity connections to a plurality of shared-media and dedicated-media service gateways, using multi-carrier bands or spectrums. On activation of present embodiment transceiver (12a) in step 110, the program started boot-up transceiver's operating system in step 111 which serves as Network Access Control (NAC) means (20), and load the appropriate network protocols and handshake/signaling protocols in step 12.

Said transceiver (12a) utilizes said NAC (20) and its Data-Link Control (D-LC) (21) components, for the establishment of connections among its sub-net devices and/or to any external connected network devices. Upon complete, transceiver ( 2a) could now be able to proceed to establish a connection listening port process in step 113 and broadcast its availability for providing interconnection and internetworking to its sub-nets.

Transceiver (12a) would then activate step 4 process which tests each carrier/channel bands to determine the Signal Noise Ratio (SNR) for each carrier band, as well as periodically thereafter. Said NAC (20) records the result of its SNR test along with its allocated "bits per bin" for each channel band within its Bandwidth Resource database. Unlike prior art, present embodiment's Bandwidth Resource database (27) contains fields for carrier band identification, SNR reading, allocated "bits per bin" value, SNR rating, and a field to identified whether or not said carrier band had been in use.

Upon completion of step 1 15, said transceiver (12a) would dial-up to its interconnected DSLAM device's call establishment listening port and registered its call establishment listening port with said DSLAM (13). Upon successful completion of step 1 15, said transceiver's NAC (20) is now ready to start accepting and processing its sub-nets internetworking connection requests, as well as, requirements through step 116. Said transceiver (12a) NAC (20) then enquired its User .Network Connection Profile database (26) to determine the type of interconnection and internetworking its allowed to support.

In the initial activation process 110 till completion of step 116, and without any constraint of interconnection and internetworking, said NAC proceed to step 117 which determine whether or not there is a need for establishing VD I connectivity. If yes, the process then proceeds to step 118, otherwise it proceeds to step 119. In step 119, said NAC (20) determine whether or not there is a need for establishing hybrid network connectivity. If yes, the process then proceeds to step 120, otherwise it proceeds to step 121. In step 121 , said NAC (20) determine whether or not there is a need for establishing MPLS-enabled VPN connectivity. If yes, the process then proceeds to step 122, otherwise it proceeds to step 123. In step 123, said NAC (20) determine whether or not there is a need for establishing connectivity to the Internet. If yes, the process then proceeds to step 124, otherwise it proceeds to step 125 whereby said NAC (20) is in a waiting-mode state to receive connection and call establishment requests for internetworking from its sub-nets or from external caller party.

Fig. 11 flowchart depicts the method for the subscription and establishment of Internet services. Either from step 123 of transceiver ( 2a) activation process or a request from a sub-net device for Shared-Media Internet (SMI) Internet connectivity services, said NAC (20) proceed to step 124 which is to establish SMI connectivity from said transceiver (12a) through said DSLAM (13) to its subscribed ISP gateway. Upon receipt for step 124 process, said NAC retrieve Internet network connection information from its User Network Connection Profile database (26) in step 400 and proceed to step 401.

In step 401 , said transceiver (12a) signal its interconnected DSLAM (13) call establishment listening port for connection establishment to the requested ISP gateway for a communication channel. Upon success of said procurement for connection to said DSLAM ( 3), transceiver (44) would then allocate the prescribe amount of either sequential range of carrier bands or carrier bands having low QoS classification for connectivity to- said public Internet service via DSLAM and said ISP gateway to procure ISP for Internet services, and record said allocated channel band identification within its Network Connection database (28) in step 402. Said NAC (20) also request to obtain an IP address from ISP gateway for its usage in step 403. Upon success of step 403, NAC is now able to implement step 404, which is the ability to receive and send IP packets from its sub-net to its connected ISP gateway.

Another unique feature the present embodiment had over prior art is the ability to increase and decrease the bandwidth allocated for the communication channels. Fig. 12 depicts the xDSL algorithm flowchart for enabling the transceiver to change the allocated bandwidth resource of a connection. Upon receipt of instruction for the need to increase or decrease the amount of bandwidth, said NAC (21) activated process (128).

When step 128 invocation/procedural call had been issued, step 301 evoked the process for processing the request to increase or decrease the allocated bandwidth for upstream and downstream channel bands. For increasing of bandwidth procedure, said NAC (20), with reference to bandwidth resource database (27), determine whether or not there is any available channel band to be allocated for the requested amount. If no, it informs the requester there is no available resources. If yes, it proceeds to step 302.

In step 302, said NAC (20) through said D-LC (21) signal to its interconnected DSLAM's call establishment listening port to request for change of Quality of Service (QoS) for said allocated transmission connection. On receipt of approval to change the bandwidth from said DSLAM (13), said transceiver ( 2a) invoke step 303, and supply the channel band IDs to be added or dropped for said connection. Upon obtaining conformation from said DSLAM (13) that said requested had been executed, said NAC (20) registered said changes in channel bands allocation by flagging or unflagging the "In-Use" data field for said channel band IDs in said Bandwidth Resource database (27) and registered said changed in allocated channel bands in its Network Connection database (28).

Upon completion of step 304, NAC (20) proceed to step 305, which implements the process to termination connection with said DSLAM (13) network control/signaling port for the undertaking of this process.

Fig. 13 flowchart depicts the method for the subscription and establishment of IP- based associative addressing-enabled VPN connectivity services. Either from step 121 of transceiver (12a) activation process or upon a request from a sub-net device for MPLS- enabled VPN connectivity service, said NAC (20) proceed to step 122 which is to establish connectivity from said transceiver (12a) through said DSLAM (13) to its subscribed VPN gateway. Upon receipt of step 122's procedural call, said NAC (20) retrieves said MPLS- enabled VPN's network connection information from its User Network Connection Profile database (26) in step 500 and proceed to step 501. In step 501 , said transceiver (12a) signal its interconnected DSLAM's call establishment listening port to request for connection to the requested ISP gateway for a communication channel. Upon success of said procurement of connection to said DSLAM (13), transceiver (12a) would then allocate the prescribe amount of either sequential range of carrier bands or carrier bands having low to moderate QoS classification for said transmission channel connectivity via DSLAM to said MPLS-enabled VPN gateway to procure for secure Internet service from said VPN ISP, and record said allocated channel band identifications within its Network Connection database (28) in step 502. Said NAC (21) then registered its IP address with said MPLS-enabled VPN gateway for its usage in step 503.

At the MPLS-enabled VPN gateway, through used of tunneling methodology, said gateway associated said transceiver's IP address to its label or associative addressing and record said addressing information within its user/endpoint session translation database. The MPLS-enabled VPN gateway uses said user/endpoint session translation table for both address resolution, routing when inserting or removing said MPLS shim header for said transceiver IP packets. Said MPLS-enable VPN gateway, then encrypted and encapsulated said IP packets within another IP packet having MPLS associative addressing and route, through destination forwarding, through its label-swapping and circuit-switching based network. Upon success of step 503, NAC is now able to implement step 504, which is the ability to receive and send IP packets from its sub-net to its connected MPLS-enabled VPN gateway.

Its is normal, that a call establishment may originated from a circuit-switching network system, but the network system could either be end-to-end circuit-switching topology or an combination of circuit-switching and packet-switching network topology, such as 3G and 4G systems. If the interconnect comprises of a hybrid of packet and circuit switching systems then end-to-end, connection-oriented and circuit-switch internetworking environment does not exists. The below procedural flowcharts describe the process for determining and processing hybrid network and VDM1 connectivity establishment. Present embodiment transceiver (12, 12a), operating in server-mode, have a registered call establishment listening port from it to the DSLAM and vise-verse. Step 200 to step 205, as illustrated in Fig 14 and Fig.15, are the process to implement such capability. Request for connect would originated from subscriber through invocation for connection to a called party in step 200, or from external through call establishment request from DSLAM through transceiver (12, 12a) call establishment listening port from a caller party in step 203.

Should the connection establishment origin from process 200, transceiver NAC (20) retrieve the requesting user/sub-net connection information from User Network Connection Profile database (27) and, if required, from Virtual Access Control Configuration Protocol database said requesting user/sub-net connection information. NAC (20) process said user/sub-net connection information to determine whether or not said user/sub-net is allow for connection to said called party, or whether or not the connection will utilizes for VDMI- based application. In step 202, should NAC determine the connection is for VDMI application, its route the process to step 118, otherwise the connection process is routed to 120.

Fig. 14 flowchart depicts the method for the subscription and establishment of hybrid network system connectivity sessions among disparate connection-oriented and connectionless network system topology. When the call establishment process is routed to step 120, NAC (20) through DL-C (21) signaled its connected DSLAM call establishment listening port to negotiate for connection to called party/endpoint, or, if caller party does not have access authority, said NAC (20) deny and terminate said call establishment in process 606. Should said connect was approved, NAC (20) activated process 607 to establish connection.

Upon success of said procurement of connection to said DSLAM, transceiver (12a) would then allocate the prescribe amount of either sequential range of carrier bands or carrier bands having moderate to high QoS classification to said called or caller party connection via DSLAM and said hybrid network systems, and record the allocated channel band identifications within its Network Connection database (28) in step 607. Said DSLAM through said VCC gateway would obtained and registered a Virtual Path Identifier/Virtual Circuit Identifier (VPI/VCI) address from said VCC network central controller or MPLS- enabled circuit-switching controller during process 608. Upon completion of step 608, the user/end-point is now able to send and receive information packets through said VCC channel/MPLS label-swapping circuit until terminated.

Fig. 15 flowchart depicts the method for the subscription and establishment of end- to-end, connection-oriented and circuit-switching connectivity for VD I-based application services. When the call establishment process is routed to step 1 8, NAC (20) through DL- C (21) signaled its connected DSLAM call establishment listening port to negotiate for connection to said called party/endpoint, or, if caller party does not have access authority, said NAC (20) deny and terminate said call establishment in process 206. Should said connect was approved, NAC (20) activated process 207 to establish connection.

Upon success of said procurement of connection to said DSLAM, transceiver (12a) would then allocate the prescribe amount of either sequential range of carrier bands or carrier bands having high QoS transmission classification for connectivity to said called or caller party via DSLAM to an entirely end-to-end circuit-switching network system topology, and record the allocated channel band identifications within its Network Connection database (28) in step 207. Said DSLAM through said VCC gateway would obtained and registered a VPl/VCI address from said VCC network central controller during process 208. Upon completion of step 208, the user/end-point is now able to send and receive information packets through said VCC channel until terminate.
