The present invention relates to a system and method for configuring subscriber information according to the movement of a terminal in a next generation network (NGN), and more particularly, when a terminal moves in an NGN, the terminal does not configure information of a subscriber through an operation management system. The present invention relates to a subscriber information configuration system and a method of directly configuring a soft switch and a common storage using the transmitted REGISTER message.

Recently, various voice-based services, which have been provided by circuit switching, are being converted to NGN, in which service network elements are all integrated and provided in a packet-based system. At this time, the soft switch, NGN's network element, accepts various terminals through IP (Internet Protocol) delivery network to provide call processing and additional services. IP terminals and Session Initiation Protocol (SIP) protocols are defined. Among them, request registration by using the message REGISTER to receive service from the corresponding soft switch. Of course, the soft switch only provides the call processing service to the subscriber terminal based on the information only when the soft switch receives the corresponding information from the upper operation management system managing the information received from the subscriber.

As shown in Figure 1, the subscriber first subscribes to the service provider by phone or in writing in order to receive the service (S1).

Then, the service provider (in this case, the common description of the service provider providing information to the system is referred to as the upper management system (2).) The subscriber information (subscriber name, ID (terminal), password, residence address to process the subscription subscription). Etc.) and the service information is received and subscription subscription processing is performed (S2).

The common storage 3 that receives the subscription request (S3) from the operation management system 2 is a system for managing all subscriber information, and receives subscriber information from the operation management system 2 based on the subscriber information. The corresponding soft switch (here, soft switch A (4)) is determined (S4), and the configuration command is transmitted to the soft switch A (4) (S5).

The soft switch A (4) receiving this processing receives and processes the configuration command, stores the subscriber information (S6), and then transmits the configuration completion information to the common repository 3 (S7).

This configuration completion information is notified to the subscriber through the common storage (3) and the operation management system (2) (S8, S9), after which the subscriber terminal 1 is a soft switch that is in charge of its own call processing via the access network A REGISTER message for requesting registration to A (4) is transmitted (S10).

The soft switch A (4) verifies the received REGISTER message, confirms whether it is information about the subscriber received and stored through the operation management system (2) and the common storage (3) and completes the subscriber registration (S11). The terminal 1 notifies the subscriber registration completion (S12).

The subscriber station 1 having received the registration completion information may transmit an INVITE message to attempt a subsequent call (S13). The soft switch A (4) receiving the INVITE message proceeds to call processing (S14).

If the subscriber later moves to the place of the terminal 1 (continued in FIG. 2), the subscriber requests a place change subscription (S15) by telephone or in writing to the service provider (S15), and the operator changes the place. Processing must be performed.

The operation management system 2 receives the address of the new residence, performs a place change process (S16), and requests a change of information from the common repository 3 (S17).

After receiving the changed information of the subscriber from the operation management system 2, the common repository 3 determines the corresponding soft switch (herein, the soft switch B (5)) based on the subscriber information (S18), and firstly, the previous subscriber. The delete command for the subscriber information is transmitted to the soft switch A (4) which constituted the information (S19), and then the configuration command is transmitted to the soft switch B (5) (S22).

After receiving the delete command for the subscriber, the soft switch A 4 deletes the related information (S20) and transmits the deletion completion information (S21). The common storage 3 which received the deletion completion information from the soft switch A 4 transmits a configuration command to the soft switch B 5 (S22). After receiving the configuration command, the soft switch B 5 stores the subscriber information (S23) and transmits the configuration completion information to the common repository 3 (S24).

The common store 3 updates subscriber related information (ie, information that the soft switch is the soft switch B (5)) (S25) and then the subscriber soft switch of the terminal 1 to the subscriber through the operation management system 2 (S25). The change completion information of the soft switch B 5 is notified (S26, S27).

 Thereafter, the subscriber station 1 transmits a REGISTER message requesting registration to the soft switch B 5, which is in charge of its own call processing, through the access network of the changed region (S28).

The soft switch B (5) verifies the received REGISTER message, confirms whether it is information about the subscriber received and stored through the operation management system (2) and the common storage (3) and completes the subscriber registration (S29). The terminal 1 notifies the subscriber registration completion (S30).

The subscriber station 1 having received the registration completion information may transmit an INVITE message to attempt a subsequent call (S31). The soft switch B 5 which receives the INVITE message proceeds to call processing (S32).

In NGN, all information is transmitted using IP, and subscriber terminal has a characteristic of changing location. If such fluctuations occur frequently, as described above with reference to Figs. 1 and 2, the subscriber has to be notified of information to the operator every time, according to the movement. The cost increases. In addition, if this operation is not performed smoothly, the subscriber may not be provided with the service, and even if provided, the service may be delayed due to a system failure or delay.

In order to solve the above-mentioned problems, an object of the present invention is to directly configure subscriber information by interworking a soft switch and a common store when the subscriber station moves to configure a new subscriber information in the NGN.

Another object of the present invention is a soft switch has a function for distinguishing its own IP zone (Zone) and a function for requesting the registration of the terminal to the common storage, the common storage is a function and soft switch for managing the soft switch for each IP zone It has a function of processing a registration request of a terminal from the terminal, when the subscriber terminal is moved to newly configure the information of the subscriber through the soft switch and the common storage.

To this end, the subscriber information configuration system according to the movement of the terminal in the NGN according to the present invention, and manages the IP zone included in the self, and manages the personal information and service information of the registered subscriber, the terminal of the subscriber A soft switch configured to configure and register information of the subscriber by determining whether the subscriber is registered when receiving a REGISTER message from the mobile station; It manages the IP switch and IP-based softswitch for each zone, manages the personal information and service information of registered subscribers, and when the registration request of the subscriber is received from the softswitch to the softswitch corresponding to the subscribers Characterized in that the common storage for commanding the configuration of the information.

According to the present invention, a method of configuring subscriber information according to movement of a terminal by interlocking a soft switch and a common store in an NGN, wherein the soft switch receiving a register message from the terminal receives subscriber information and subscriber configuration information of the terminal. A first step of inquiring and requesting registration processing of the subscriber from the common repository; A second step of inquiring of the soft switch information corresponding to the terminal by the common store receiving the registration processing request of the subscriber and instructing the soft switch to configure the information of the subscriber; A third step of the soft switch processing the information configuration of the subscriber and transmitting configuration completion information to the common repository; A fourth step of the soft switch transmitting the registration completion information of the subscriber to the terminal; And a fifth process of the common repository changing the soft switch information of the subscriber.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.                     

3 is a block diagram of a common storage 30 according to the present invention.

As shown, the common storage 30 according to the present invention includes a soft switch manager 33 to manage the IP zone-based soft switch and the address-based soft switch, and has a registration processor 34 to process subscriber registration. It is characterized by performing a function.

When the subscriber information new processing unit 31 receives the subscriber information configuration command from the operation management system, the soft switch management unit 33 inquires which soft switch corresponds to the subscriber and transmits the configuration command to the soft switch. When the soft switch corresponding to the subscriber is changed due to the movement of the subscriber, the delete command is transmitted to the previous soft switch and the configuration command is transmitted to the changed soft switch. When the configuration is completed, the subscriber information store 32 stores the subscriber information and service information.

When the registration processing unit 34 receives the registration processing instruction of the subscriber from the soft switch, the registration processing unit 34 inquires the soft switch management unit 33 based on the subscriber information (IP zone, ID). When the registration processing unit 34 receives the information of the soft switch corresponding to the subscriber of the current position from the soft switch management unit 33, the contents to be deleted by the subscriber information new processing unit 31 (the soft switch and subscriber corresponding to the previous subscriber). Information (ID) and information to be configured (soft switch corresponding to the current subscriber's location, subscriber information (ID)). Then, the subscriber information new processing unit 31 transmits a delete command and a configuration command to the subscriber together with the contents inquired from the subscriber information storage 32 to each corresponding soft switch.

4 is a configuration diagram of the soft switch 40 according to the present invention.

The soft switch 40 according to the present invention includes an IP zone management unit 43 to manage its own IP zones, and has a registration processing unit 44 to request a subscriber registration processing to a common repository and to register a register from a subscriber station. When the message is received, the subscriber information storage 42 and the IP zone manager 43 determine whether the subscriber is being managed by the subscriber and whether the subscriber is not registered or does not correspond to his IP zone. It is characterized by performing.

When the subscriber information processing unit 41 receives the subscriber configuration command from the common store, the subscriber information processing unit 41 stores the related information in the subscriber information store 42. The subscriber information storage 42 stores subscriber information and service information of the configured subscriber. When the subscriber delete command is received from the common repository, the information is deleted.

The IP zone manager 43 manages the IP zone list of the access network managed by the soft switch 40. When the registration processor 44 receives the REGISTER message from the subscriber station, the registration processor 44 inquires whether the subscriber station exists in the management IP zone.

At this time, if the subscriber's terminal does not exist in the management IP zone, the registration processor 44 inquires of the subscriber ID by referring to the subscriber ID. When the subscriber who has transmitted the REGISTER message as a result of the inquiry of the subscriber information store 42 is a subscriber that has already configured subscriber information, the registration completion message is transmitted to the subscriber station.                     

However, in the case of the subscriber's terminal does not exist in the IP zone or the subscriber information is configured, the subscriber registration process is requested to the common repository by loading the subscriber terminal and information (subscriber ID, terminal IP zone).

5 is a flowchart illustrating a method of configuring subscriber information according to movement of a terminal in a subscriber information configuring system according to the present invention, and shows detailed message transmission and functional operations between systems.

In the present invention, since the initial new subscription subscription procedure is the same as S1 to S9 of FIG. 1, the description thereof is omitted, and the initial subscriber registration procedure is performed by the subscriber to the soft switch A 53 by the same process as S10 to S12 of FIG. 1. Assuming that it is registered, only the subscriber registration procedure according to the movement of the subscriber station 51 will be described.

Therefore, in the present invention, when the subscriber terminal 51 moves to a place, the subscriber only needs to turn on the power of the terminal 51 without requesting a change of place in writing or by telephone. When the power is changed from off to on, it transmits a REGISTER message to a soft switch (here, soft switch B 54) in the region (S51). For reference, conventionally, since a message is transmitted to another soft switch instead of the corresponding soft switch, the message is discarded from the other soft switch and the call does not proceed anymore.

After receiving the REGISTER message from the subscriber station 51, the soft switch B 54 extracts the IP zone information and the subscriber ID of the subscriber station 51 from the received message after verifying the message through the registration processing unit. In addition, the soft switch B 54 inquires the IP zone management unit based on the IP zone information extracted through the registration processing unit, and when the position where the subscriber terminal 51 currently exists is an IP zone managed by the soft switch B 54. The subscriber configuration information of the subscriber information store is inquired based on the subscriber ID (S52).

At this time, if the subscriber station 51 exists in the IP zone not managed by the soft switch B 54 or the subscriber information has not been previously configured, the soft switch B 54 goes to the common storage 52 through the registration processing unit. The subscriber registration process is requested (S53).

When the common storage 52 receives the subscriber registration processing request transmitted from the soft switch, it determines which soft switch is based on the information (subscriber ID, IP zone, transmission soft switch) received from the soft switch through the registration processing unit. The soft switch management unit is inquired, and the subscriber new processing unit transmits the deletion information of the soft switch A 52, which is an existing soft switch, and the configuration information of the soft switch B 53, which is the soft switch at the current position (S54). Then, the subscriber new processing unit of the common storage 52 first transmits a delete instruction for the subscriber information to the soft switch A 53 which has constituted the previous subscriber information (S55), and then the configuration command to the soft switch B 54. (S58).

After receiving the delete command for the subscriber, the soft switch A 53 deletes the related information (S56) and transmits the deletion completion information (S57). The common storage 52 which has received the deletion completion information from the soft switch A 53 transmits a configuration command to the soft switch B 54 (S58). After receiving the configuration command, the soft switch B 54 stores the subscriber information (S59), and then transmits the configuration completion information to the common repository 52 (S60).

When the subscriber information configuration is completed in the soft switch B 53 as described above, the registration completion information including the corresponding soft switch information is transmitted to the subscriber (S61).

After the operation is successfully completed, the common storage 52 records and changes the soft switch from the soft switch A 53 to the soft switch B 54 in the subscriber information (S62).

Thereafter, the subscriber transmits the INVITE message using the received information of the soft switch B 54, and the soft switch B 54 proceeds to call processing (S63 and S64).

As described above, according to the present invention, when the subscriber's terminal moves, the soft switch receiving the register message configures the subscriber information in association with the common store, so that the subscriber always changes the address even if the subscriber terminal moves locally. Even if you do not report to the operator there is an effect that the service can be made quickly.

In addition, the service quality can be improved by eliminating the hassle of registering the subscriber change information, and the service breakdown time can be reduced for the service provider, thereby increasing the possibility of the call of the subscriber, thereby increasing the call revenue.
