SYSTEM FOR TESTIFYING SERVICE SCENARIO BASED ON MOBILE COMMUNICATION NETWORK AND METHOD THEREOF [Technical Field]

The present invention relates to a service scenario verification system on a mobile network and a method thereof, and more particularly, to a scenario service verification system capable of verifying a scenario for value added services provided over the mobile network by using messages transmitted/received and collected from respective systems included in the mobile network, and a method thereof. [Background Art]

A plurality of systems, such as MSC, BSC, HLR, SCP, SMSC, etc, are included in a mobile network. When a new software or hardware package is applied to the respective systems, or when a network problem occurs, a network operator verifies the package or tests the network in order to ensure network reliability and stability. When the network is tested, or a specific package is verified, a conventional method has been used for debugging an internal logic of each system's software, or analyzing a transaction with respect to an adjacent system according to data displayed on an operating terminal by using a system

tracing function through a man machine command of the operating terminal.

Moreover, in order to analyze a connection relationship between systems included m the overall network, actual calling may be made so that the connection relationship can be decided according to the result thereof.

Generally, in the conventional verification method, verification is manually achieved by operators. Therefore, when packages have to be frequently replaced in a system, verification of the packages becomes a problem in terms of long time consumption and high labor costs. In addition, when a problem occurs while a connection relationship is verified between systems included in the overall network, it is very difficult to decide which system erratically operates in the network. In this case, verification consumes human resources and time significantly.

Meanwhile, as mobile value added services (for example, pre-paid subscriber, call forwarding, etc) gradually become various, network operators face a lot of troubles in order to verify the services whenever the services are developed, because there is no appropriate method capable of properly verifying the systems and the overall mobile network according to a scenario for each service.

[Disclosure] [Technical Problem]

[Best Mode] Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings .

FIG. 1 is a block diagram schematically illustrating a structure of a service scenario verification system 10 according to an embodiment of the present invention.

Referring to FIG. 1, the verification system 10 includes a central controller 100, a call generator 110, a service controller 120, an integral call analyzer 130, a message collector 140, and a user operating computer 150. Now, the aforementioned elements will be described.

First, the central controller 100 controls an overall operation of the verification system 10, receives information required for a call simulation, and instructs the call generator 110 to generate a call according to the received

information. That is, when an origination phone number and a destination phone number desired to be found by a user are input to the central controller 100, the verification system 10 traces a call transaction related to a call for the origination and destination phone numbers input by the user from all nodes on a mobile network. Then, the verification system 10 provides an analysis result thereof.

Further, the central controller 100 provides a user interface of the verification system 10, synchronizes each module of the verification system 10, and performs general control .

The user operating computer 150 includes a scenario editor which requests the central controller 100 to check or modify a subscriber service profile, or edits or forms a scenario pattern for a specific value added service provided over a mobile network. Further, the user operating computer 150 can transmit the service scenario pattern formed using the scenario editor to the central controller 100. Details of the scenario editor will be descried later. The central controller 100 transmits a service scenario pattern input from the user operating computer 150 to the service controller 120, or transmits call information to the call generator 110 according to a service scenario verification request from the user operating computer 150.

The call generator 110 automatically generates a call for the origination and destination phone numbers requested from the central controller 100 by using a terminal according to an instruction requested from the central controller 100. The service controller 120 provides a service scenario test environment. Further, the service controller 120 checks or modifies a subscriber service profile in association with external systems related to a specific service. In order to provide the service scenario test environment, the service controller 120 includes a scenario database. The scenario database stores and manages scenario patterns for a value added service transmitted from the central controller 100. When a specific scenario pattern is requested from the integral call analyzer 130, the service controller 120 reads the scenario pattern, and transmits the result thereof to the integral call analyzer 130.

When a subscriber service profile check or modification is requested from the central controller 100, the service controller 120 accesses to a system included in a mobile network through which the subscriber service profile is stored and managed, thereby checking or modifying content of the subscriber service profile.

The message collector 140 collects messages of a No.7 protocol signal transmitted/received between systems included

in the mobxle network, and multiplexes the collected message by attaching a collected time and a node information tag. Thereafter, the message collector 140 converts the multiplexed message into a TCP/IP signal, and transmits the TCP/IP signal to the integral call analyzer 130. The message collector 140 may be included in the verification system 10. Alternatively, as an independent unit with respect to the verification system 10, the message collector 140 may be disposed outside the verification system 10, and transmit information to the verification system 10. Meanwhile, in a section for transmitting/receiving signals by using a TCP/IP protocol among system sections constituting the mobile network, the integral call analyzer 130 can collect a message without via the message collector 140. The integral call analyzer 130 decodes messages transmitted from the message collector 140 or the like, and stores the decoded messages in a call information database. Further, the integral call analyzer 130 detects messages related to the call generated by the call generator 110 so as to form a call flow. After forming the call flow, the integral call analyzer 130 receives a scenario pattern for a value added service to be verified from the service controller 120, and verifies a scenario by comparatively analyzing the scenario pattern and the call flow. Then, the

integral call analyzer 130 transmits a verification result to the central controller 100.

FIG. 2 is a flowchart sequentially illustrating a modification process of a subscriber profile during the verification system 10 having the aforementioned structure operates. Referring to FIG. 2, by using the operating computer 150, a user requests a profile of a specific subscriber to be checked or modified (step 200) , and then the central controller 100 received information thereof sends the request to the service controller 120 (step 210) . The service controller 120 accesses to a system included in a mobile network through which the subscriber service profile is stored and managed so as to check or modify the subscriber service profile (step 220) . Information on the checked subscriber service profile is transmitted to the user operating computer 150 via the service controller 120 and the central controller 100 (steps 230 and 234) .

FIG. 3 is a flowchart sequentially illustrating a service scenario verification process during the verification system 10 having the aforementioned structure operates. Referring to FIG. 3, an operator edits and forms a scenario for a specific value added service by using the user operating computer 150, and transmits the result thereof to the central controller 100 (step 300) . The scenario

transmitted to the central controller 100 is re-transmitted to the service controller 120 (step 310) , and is registered in a scenario database to be managed (step 320) .

When an origination/destination phone numbers is input by the operator, and a scenario verification is requested for a specific value added service (step 330) , the central controller 100 transmits the origination/destination phone numbers for verifying the scenario to the call generator 110, and reguests call generation (step 340) . The call generator 110 received the call generation request generates a call according to the origination/destination phone numbers by using a terminal (step 342) .

The message collector 140 collects messages transmitted/received between nodes on the mobile network, and transmits the messages to the integral call analyzer 130 (step 350) . The integral call analyzer 130 extracts messages related to the call generated by the call generator 110 from the collected messages, thereby forming a call flow (step 352) . The integral call analyzer 130 requests the service controller 120 to transmit a service scenario pattern (step 360) . After receiving the service scenario pattern (step 362) , the call flow is compared with the service scenario pattern, thereby verifying the service scenario (step 370) . The verification result is transmitted to the central

controller 100 and the user operating computer 150 (steps 380 and 382) .

Now, a structure and operation of a scenario editor 40 executed on the user operating computer 150 will be described in detail with reference to FIG. 4. Referring to FIG. 4, the scenario editor 40 includes a system database 400, a message database 410, a system design unit 420, a message design unit 430, and a storing unit 440.

The system database 400 stores and manages information on systems included in the mobile network. The message database 410 stores and manages messages transmitted/received between the respective systems.

The system design unit 420 of the scenario editor 40 disposes one or more systems selected by a user from the system database 400 to specific positions. The message design unit 430 disposes messages transmitted/received between the systems selected by the user from the message database 410 to specific positions. Next, when the systems and messages are selected and disposed, the storing unit 440 determines a name of the scenario pattern and stores the name and the selected systems and messages with their position.

Then, the procedure is ended.

FIG. 5 illustrates an example of a scenario pattern formed by the scenario editor 40.
