TECHNICAL PROBLEM In the architectures which are used at present, service platforms are located in that network element which bridges the home network with the access network. These solutions are impaired by a number of problems.

The Residential Gateways, RG, which at present are utilized are expensive from a technical and economical point of view, which in this context relates to the technical and software development which rapidly makes the equipment in need of updating.

The Residential Gateway, RG, constitute a bottleneck with the location referred to, since all traffic has to go through the Residential Gateway, RG, because these do not manage to deal with the demands of certain services (for instance TV or telephony over IP). To build a Residential Gateway, RG, sufficient powerful to manage the demands would make it even more expensive.

The technical length of service of a Residential Gateway, RG, is short because the development in the electronic field, as well as in the field of software, is rapid, which results in that a Residential Gateway, RG, can be expected to have a length of service of maximum two years before it is ripe for exchange. From an economical point of view this is to the detriment of the user if he/she then has to exchange all parts of the RG. For that reason it is of advantage if only these parts which really need to be exchanged are exchanged or upgraded, and that the user does not need to care about the exchange. Further problems with

the existing solutions are that different versions of the RG may be in the network, which results in risk for communication problems if these partially or wholly cannot communicate with each other. There therefore is a strong wish that at least those parts of the RG of today which have short length of service, or have to be upgraded at short intervals, are maintained centrally and are not depending on respective user's want and ability to take current actions. Further, there are wishes that the number of RGs in the network is kept at a low level to be possible to manage rationally.

The present invention is intended to solve mentioned problems.

PRIOR ART A number of proposals for service platforms for the home are at present examined. One example of such a platform is OSGi, Open Service Gateways initiative. The platform is intended to have ability to include different types of services, for instance services for power control/control of electrical devices in the home, support for plug-and- work technologies, and makes remote connection to the home possible in a safe way. Services are installed and uninstalled dynamically at the user's request, and the services are managed by the platform with a minimum of administration from the user. The matter everybody is discussing today is that this platform should be located in the home together with that network element which bridges between the home network and the access network, a so called Residential Gateway, RG.

In Figure 1 the above mentioned technology is shown. In a home network, H, one or more computers are included. The computers, which are part of a circuit/circle, are connected towards a home network via a Residential Gateway, RG. The Residential Gateway, RG, constitutes a bridge between the home network and the access network, A. Between the access network, A, and the Internet, I, an access node

is introduced. The different service platforms which are needed in this solution are based on the introduction of Residential Gateway, RG, in direct or close connection to the home. Service platforms and network elements are in this case integrated into one component.

THE SOLUTION The present invention relates to a device and method at information networks and computer networks (henceforth called telecommunication networks) for creation of customer adapted provision of services. A first device (G), group server, is arranged in the telecommunication network. The device is arranged to define the customer's service access/availability. A second device (A) is arranged to transmit the information individually to the customers.

Further, the customers are connected to a network (H). The network (H) includes one or more customers, which customers are arranged to be allocated individually adapted services.

The second device (S) is transparent and is used to connect the home network (H) to the access network (A).

Control/routing of the services and information to respective user is managed by device (G).

The first device (G) further controls/routes the customers in the network (H). The first device (G) is connected to the access network via a node (N) which is arranged in the telecommunication network before the access network (A).

The meaning of this is that the node (N) is located between the access network (A) and the Internet (I) as example of an information network. The information and the services are further routed by the node (N) to respective network (H) on basis of routing/control information provided by the first device (G). In the first device (G), further a number of modules (T) are arranged. Said modules (T) further include definitions for respective customers, which definitions define the service allocation of respective customers. The modules (T) include means which defines a channel allocation which is needed to establish and execute

respective services, which respective customers requests to utilize during an establishment of respective utilization of a defined set of services. The second device (S) is here further arranged to receive the channels which relate to the for the second device (S) destined channels, and that the second device (S) is arranged to allocate respective channels to respective customers.

The modules (T) are further arranged to, on the one hand, be allocated a general definition of service allocation of respective customers, and on the other that the customers, within the frame of this definition, are allowed to provide definitions regarding a utilization of these services. On basis of these definitions, the modules further are arranged to allocate, to respective customers, channels which correspond to the current need. Further, each channel is allocated, according to need, a varying information bandwidth. The information is transmitted to the customers via an information network (I). The second device (S) is further allowed to be a hub or a switch. The second device is allowed to be a single computer in the case the network (H) consists of one single computer.

ADVANTAGES The suggested solution has the advantage that it separates the service platform from the network element. The service platform, which need frequent modifications, is easily accessible/available and is not depending on respective user's arbitrariness. This also means that components which are critical for the functionality can be expected to get, if not the same upgrading, at least an upgrading which corresponds to a guaranteed functionality. Further, the problem that the RGs of today do not fulfill the demands for bandwidth at transmission of information is bridged.

The at present short service length of the RG does not burden the customer.

The invention further makes it possible that persons in, for instance, a household are allowed to communicate with equipment of different kinds at the own home. At that,

different devices such as lighting, electrical devices, doors and windows can be opened or closed, alternatively be locked or unlocked. This provides possibility for the user to control the home or other premises. Further, a server is created which has the functionality of a plurality of sub servers. Each sub server functions as a separate server for a home network (H) and at that has the same functionality as if the sub server had been physically located in connection with respective home network. The home networks are in this connection allowed to relate to both private networks and networks belonging to smaller firms, associations or the like.

DESCRIPTION OF FIGURES Figure 1 shows example of solution according to the prior art.

Figure 2 shows the solution according to the present invention.

PREFERRED EMBODIMENT In the following, the invention is described on basis of the figures and the terms in them.

The invention is based on that a group server is created, which is based on that the service platform is moved from the network element in the household to a server in the access (access node). This server holds the service platforms for all households in the access. In spite of this, each household shall have only its own platform and not have access to any other's.

The present invention relates to a device for customer adapted provision of services. For the purpose a service platform (G) connected to a node in a communication network is created. The node is connected with an access network (A) in which network elements (S) are connected to a local network (H), to which users are connected. The service platform further includes a number of modules (T) which are individual for each user group. The modules (T) further are divided into a number of sub modules (Tl) corresponding to

individual users. These sub modules (Tl) define the available offer of services of the users. At the establishing of a communication, alternatively during a communication in progress, the user defines the services that shall be utilized, at which the service platform (G) allocates to the user a channel bandwidth which corresponds to the current need.

The solution means that the network element (in the home) can consist of a common hub, switch or the like, and does not constitute any bottleneck.

The solution further is more cost-effective since a plurality of households/users share the same hardware, in the case they are in the same network.

The households/users further are not affected by the technical service length.

According to the invention, a group server (G) is introduced between the access network (A) and the Internet (I). The group server is connected to an access node in the connection between the access network (A) and Internet (I).

The group server (G) further includes a number of service platforms (Tl) included in a module (T). Each service platform includes a definition for respective users in the system. This means that the service platform defines which services each user shall have access to. One and the same group server (G) consequently is divided into a number of service platforms (Tl) which are allocated definitions regarding utilization of services by the network operator, based on the wishes of the users, and on basis of the user's own definitions which are transmitted via computers or terminals in the home. The information which is transmitted to/from a user is controlled/routed by respective service platform (Tl) in such a way that the information is routed to right user and that respective user is allocated a channel bandwidth which is needed in the specific case.

The connection between the access network (A) and the user's network (H) is made via a network element (S). The

network element can consist of a hub, switch or just a computer.

The invention consequently means that a Residential Gateway, RG, is separated into two parts, a network element (S) and a module (T) including a number of service platforms (Tl). The network element (S) is in this way allowed to be for instance a hub, switch (consumer switch) or, if the customer only has a PC, a PC.

A user who is connected to a home network, H, intends to utilize services via an information network (I). The information relate to, for instance, information retrieval, communication or film transmission. The different alternatives require different bandwidths for the information transmission. In the system there is a gateway arranged, which includes definitions for which services the user is allowed to utilize and which channel bandwidths that can be allowed. Each user is allocated a bandwidth (Tl) in the group server, called service platform. Which bandwidth includes the definitions that are required for different communications for which the user is authorized.

The service platform (Tl) further has means for reception of information from the network via one in the network arranged node (N). The node transmits information to the service platform regarding available bandwidth in the channels which can be utilized on each occasion.

The home network (H), to which the user is connected, communicates towards the access network (A) via a network element which transmits the information between the home network (H) and the external network. The transmission to respective users in the home network (H) is made according to methods which are previously known by the expert, which for instance includes separation between different users in a local network. When the user establishes a communication, information is transmitted via the node (N) to the user's service platform (Tl) in the group server (G). Check is after that made whether requested services are available/accessible and that the user is authorized to utilize the services in question. The user's service

platform (Tl) after that decides which resources that shall be allocated for the communication. The allocation is made by information being transmitted to the node (N) about which resources and channels that shall be allocated for the user's communication. Information regarding selected channels etc is transmitted to the home network (H) to make it possible for the users to identify the information they have been allocated, and that other users in the network shall not be able to read the information in question.

After that, the user can on the one hand communicate with other users in other home networks, or utilize services of different kinds which are offered via the network.

During the progress of the communication, the service platform (Tl) checks continuously, by communication via the node (N), whether the channel bandwidth is sufficient with regard to the communication in question. Further, the service platform (Tl) modifies, when necessary, the allocated user's channel bandwidth with the intention to achieve an efficient utilization of the available resources of the network. A session in progress can include a varying need for channels and channel bandwidths, depending on changed service utilization during communication in progress, or as a consequence of that the amount of transmitted information varies by time during the session in progress. The invention can be used to utilize services in existing telecommunication networks, respective in different information networks such as Internet. Further, the invention is utilized, for instance, for control of different functionalities in a home. These functionalities can be locking/unlocking of doors, control of electrical devices, lightning etc in the home or other premises. The invention consequently provides a tool which can be utilized, for instance, in the intelligent homes of the future, or in other contexts where this technology is applicable. Further, the users normally are allocated public and private IP-addresses. The private IP-addresses are only intended to be utilized within the home network (H), whereas the public addresses are utilized at

communication outside the home network. The private addresses shall not be transmitted out on, for instance, Internet. Within respective home network, or within specified areas, there further is possibility to transmit information to all within one or more groups, or to defined persons within the groups. The groups at that can partly or wholly overlap each other.

The definitions which are required to control different devices in the home are introduced in respective service platform (T), at which different authorities are allowed to be allocated to each individual according to the definitions in that part of the service platform (Tl) which defines the allocation of the services of the individuals.

The. invention is not limited to the above described example of embodiment, or to the following patent claims, but may be subject to modifications within the frame of the idea of invention.
