  Hereinafter, an embodiment for carrying out the present invention will be described with reference to the drawings. However, the present invention can be implemented in many different modes and should not be construed as being limited to the description of the present embodiment.

[First Embodiment]
FIG. 1 is a diagram illustrating a functional block configuration of the data update system. This data updating system is mainly composed of a service providing server (hereinafter referred to as CSCF) 100 that provides services to subscriber terminals and a home subscriber server (hereinafter referred to as HSS) 200 having data necessary for providing the services. And placed in a communication network in IMS.

  The communication network includes a subscriber terminal 700 used by the subscriber, a customer control server 300 that accepts requests from user terminals, an OPS 400 that accepts requests from operator terminals, and a user operated by the user when updating data. A terminal 500 and an operator terminal 600 operated by an operator at the time of data update are further arranged, and have a connection configuration as shown in FIG.

  As shown in FIG. 1, the CSCF 100 stores all data related to the subscriber terminal 700 (for example, log data such as the last incoming call number for the subscriber terminal 700) and a certain timing. The data update unit 12 is mainly configured with the data update unit 12 that reads and updates data from the data storage unit 11 and transmits the updated data to the HSS 200 to update the data of the HSS 200.

  The HSS 200 is registered in the CSCF 100 and the CSCF 100, data necessary for the service in the CSCF 100 (for example, subscriber information regarding the subscriber and the subscriber terminal 700 used by the subscriber (such as the telephone number of the subscriber terminal 700)). Data storage unit 21 that stores information on the correspondence relationship between the subscriber terminal 700 and the data update unit 22 that receives data stored in the CSCF 100 from the CSCF 100 and stores the data in the data storage unit 21. Configured.

  The CSCF 100 and the HSS 200 having such functions can be realized by an information processing apparatus having a storage unit such as a memory and a control / calculation unit such as a CPU. The processing operation can be executed by a program.

  Next, the operation of this data update system will be described. FIG. 2 is a diagram illustrating an operation sequence of the data update system according to the first embodiment.

  When an event occurs in the CSCF 100, the data update unit 12 of the CSCF 100 first updates the data stored in the data storage unit 11 based on the occurrence of the event, and the updated data Is sent to the HSS 200 (steps S101 to S102).

  Next, the data update unit 22 of the HSS 200 receives the setting request transmitted from the CSCF 100, stores the updated data updated by the CSCF 100 in the data storage unit 21 (data setting), and sends a response to the setting request. A reply is made (steps S103 to S104).

  As described above, according to the present embodiment, the CSCF 100 updates the data stored in the data storage unit 11 when an event occurs in its own server, transmits the updated data to the HSS 200, and transmits the updated HSS 200. Since the data held by the CSCF 100 can be held by the HSS 200, a service using the data held by the CSCF 100 can be realized.

[Second Embodiment]
The operation described in the first embodiment is performed every time an event occurs in the CSCF 100. However, for example, when call processing is assumed as an event example, the data update frequency in the CSCF 100 or the HSS 200 is high, and the device load on these servers may increase.

  Therefore, in the present embodiment, in order to reduce the data update frequency, (1) when the REGISTER state (registration state) of the subscriber terminal 700 is released, the CSCF 100 transmits data to the HSS 200. A first method for updating data of the HSS 200, and (2) triggered by the user or operator making a data setting request, that is, a data setting request is transmitted from an operation terminal such as the user terminal 500 or the operator terminal 600, and the HSS 200 The CSCF 100 transmits data to the HSS 200 when the request (setting request or reference request) related to the data setting request is transmitted via the HSS 200, and the second method for updating the data of the HSS 200 is described below. To do.

(About the first method)
First, the first method will be described. FIG. 3 is a diagram illustrating an operation sequence of the data update system according to the first method.

  When the REGISTER state of the subscriber terminal 700 is released, the data update unit 12 of the CSCF 100 updates the data stored in the data storage unit 11 based on the release of the state, and the updated data is updated. A setting request to be set is transmitted to the HSS 200 (steps S201 to S202).

  Next, the data update unit 22 of the HSS 200 receives the setting request transmitted from the CSCF 100, stores the updated data updated by the CSCF 100 in the data storage unit 21 (data setting), and sends a response to the setting request. A reply is made (steps S203 to S204).

  Although the operation sequence shown in FIG. 2 is basically the same, the reason for starting the data update is not an event occurrence. Therefore, the data update frequency in the CSCF 100 and the HSS 200 is reduced, and the communication network between the CSCF 100 and the HSS 200 is changed. The communication load and the device load of each server can be reduced.

(About the second method)
Next, the second method will be described. As for the second method, for example, three update processing patterns are conceivable. Hereinafter, the case where the customer control server 300 is used will be described as an example for these update processing patterns.

  First, the first update process pattern will be described. FIG. 4 is a diagram illustrating an operation sequence (first update process pattern) of the data update system according to the second method.

  When a data setting request is transmitted from the user terminal 500, the customer control server 300 adds a flag (hereinafter referred to as CTL) indicating that an inquiry is required to the CSCF 100 to the data setting request, and transmits the data setting request to the HSS 200 (step). S301 to S302).

  The CTL is an example of an inquiry signal for the CSCF 100. For example, it is used as “CTL = XX (XX is a number)”, and the presence or absence of CTL means the presence or absence of an inquiry, and the first update processing pattern to the third update processing pattern (described later) are defined by the number XX. The Here, a number indicating the first update process pattern is described, and the processes after step S304 described later are executed as the first update process pattern.

  Next, when CTL is added to the received data setting request, the HSS 200 operates as a proxy without performing data setting, and transfers the data setting request to the CSCF 100 as it is (step S303).

  Next, when the data update unit 12 of the CSCF 100 receives a data setting request with CTL from the HSS 200, the data update unit 12 updates the data stored in the data storage unit 11 based on the request, and after the update, A setting request for setting data is transmitted to the HSS 200 (steps S304 to S305).

  Next, the data update unit 22 of the HSS 200 receives the setting request transmitted from the CSCF 100, stores the updated data updated by the CSCF 100 in the data storage unit 21 (data setting), and sends a response to the setting request. A reply is made (steps S306 to S307).

  Finally, the data update unit 12 of the CSCF 100 returns a response to the data setting request received in step S303 after completing the data update in the HSS 200 (steps S308 to S310).

  Next, the second update processing pattern will be described. FIG. 5 is a diagram showing an operation sequence (second update process pattern) of the data update system according to the second method.

  Here, a case where data of the CSCF 100 needs to be used will be described. In that case, after data is once acquired from the CSCF 100, data update / data setting is performed from the customer control server 300. Details will be described below.

  When a data setting request is transmitted from the user terminal 500, the customer control server 300 transmits a data reference request with a CTL indicating that an inquiry is required to the CSCF 100 to the HSS 200 (steps S401 to S402).

  Next, when CTL is added to the received data reference request, the HSS 200 operates as a proxy and directly transfers the data reference request to the CSCF 100 (step S403).

  Next, when the CSCF 100 receives a data reference request with a CTL from the HSS 200, the CSCF 100 acquires necessary information based on the operation rule defined by the value of the CTL and returns it to the HSS 200 (step). S404 to S405).

  Next, the customer control server 300 transmits to the HSS 200 a data setting request for the data update target CSCF 100 specified based on the acquired information (step S406), and the HSS 200 sends the data setting request to the specified CSCF 100. Is transmitted (step S407).

  Then, the data update unit 12 of the CSCF 100 updates the data stored in the data storage unit 11 based on the data setting request, and then returns a response to the setting request (steps S408 to S411).

  Since the HSS 200 receives the data held by the CSCF 100 in step S404, the data setting process by the data update unit 22 of the HSS 200 may be executed in any stage after the step S404.

  Finally, the third update processing pattern will be described. FIG. 6 is a diagram showing an operation sequence (third update processing pattern) of the data update system according to the second method.

  When a data setting request is transmitted from the user terminal 500, the customer control server 300 gives a CTL indicating that an inquiry to the CSCF 100 is necessary to the data setting request, and transmits the data setting request to the HSS 200 (steps S501 to S502).

  Next, when CTL is added to the received data setting request, the HSS 200 operates as a proxy without performing data setting, and transfers the data setting request to the CSCF 100 as it is (step S503).

  Next, when the data update unit 12 of the CSCF 100 receives a data setting request with CTL from the HSS 200, the data update unit 12 updates the data stored in the data storage unit 11 based on the request, and after the update, The data is included in the response to the setting request and returned to the HSS 200 (steps S504 to S505).

  Next, the data update unit 22 of the HSS 200 stores the updated data included in the response from the CSCF 100 in the data storage unit 21 (data update), and returns a response to the data setting request received in step S502. (Steps S506 to S508).

  The first and second update processing patterns are methods that are realized within the 3GPP diameter specifications, and the third update processing pattern is a method that extends the diameter specifications (response signal extension). .

  As described above, according to the present embodiment, (1) when the REGISTER state of the subscriber terminal 700 is released, or (2) a data setting request is transmitted from the user terminal 500 or the operator terminal 600, Since the data update process in the CSCF 100 and the HSS 200 is executed when a request (setting request or reference request) related to the data setting request is transmitted via the HSS 200, the update process is executed according to the occurrence of the event. Therefore, the data update frequency in the CSCF 100 and the HSS 200 is reduced, and the communication load of the communication network between the CSCF 100 and the HSS 200 and the device load of each of these servers can be reduced.

[Third Embodiment]
In the first embodiment and the second embodiment, on the premise of the conventional technology for specifying the CSCF 100 by the HSS 200, the setting side such as the user, the operator, the customer control server 300, the OPS 400, or the like performs the update process without specifying the CSCF 100. Explained when to do.

  On the other hand, in the present embodiment, a case where the setting side specifies the CSCF 100 and performs update processing will be described. FIG. 7 is a diagram illustrating an operation sequence of the data update system according to the third embodiment.

  When data update is required, first, the user terminal 500 transmits a data reference request to the HSS 200 via the customer control server 300, and acquires subscriber information to be updated from the HSS 200 as a response (Steps S701 to S701). S704).

  Next, the customer control server 300 transmits a destination request to the HSS 200, and acquires the identification information of the CSCF 100 that accommodates the subscriber terminal 700 to be updated as a response (steps S705 to S706).

  Next, the user terminal 500 transmits a data setting request for setting update data to the update target subscriber terminal 700 to the customer control server 300 (step S707).

  Next, the customer control server 300 directly transmits the received data setting request to the CSCF 100 identified in steps S705 and S706 without going through the HSS 200 (step S708).

  The subsequent operations are the same as steps S101 to S104 described in the first embodiment (steps S709 to S714). However, the CSCF 100 returns a response to the data setting request in step S708 directly to the customer control server 300 instead of the HSS 200.

  Note that steps S705 and S706 may be executed before steps S702 and S703. Further, it is possible to include the identification information of the accommodated CSCF 100 in the data reference response in step S703, and in this case, steps S705 and S706 may be omitted. Further, steps S702 and S703 may be executed after step S713.

  Finally, any of the first to third embodiments, the first and second methods, and the first to third update processing patterns can be freely combined depending on the service specifications and the communication network form. It is. Of course, it is also possible to carry out each independently.
