Description

  The present invention relates to a technology for synchronizing subscriber information of a migration source and a migration destination when subscriber information managed in the exchange is migrated to another exchange.

  When switching subscriber information of a switch to another switch (partitioning), in order to continue providing services without problems before and after the switch, the subscriber information must be synchronized between the switch at the transfer source and the transfer destination. There is a need.

  Since subscriber information also includes information that changes every moment depending on the usage status of the user, the synchronization method is as follows. 1. Method of stopping services and performing batch synchronization There is a method of individually synchronizing individual data in subscriber information triggered by an incoming trigger (see Patent Document 1).

Japanese Patent No. 3754308

  However, in the first method, there is a problem that a service stop time occurs, and in the second method, there is a problem that the switching processing performance of the destination exchange is affected depending on traffic conditions.

  The present invention has been made in view of the above, and the problem is that the service does not need to be interrupted for the synchronization processing between the exchanges, and the effect of the synchronization processing on the exchange processing performance of the exchanges. To make it smaller.

Since it has a call processing distribution device that distributes to either of the two exchanges, it is not necessary to interrupt the service for the synchronization processing between the exchanges, and the influence of the synchronization processing on the exchange processing performance of the exchange is reduced. Can do.

  According to the present invention, it is not necessary to interrupt service for synchronization processing between exchanges, and the influence of the synchronization processing on the exchange processing performance of the exchange can be reduced.

It is a figure which shows the whole structure of a subscriber information synchronization system. It is a figure which shows the process sequence of a subscriber information synchronization system.

  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.

  FIG. 1 is a diagram showing an overall configuration of a subscriber information synchronization system. This subscriber information synchronization system is a call that distributes the processing of incoming calls received via the telephone network 10 at the front stage of the two exchanges and the exchanges to which the exchanges are divided into one of the exchanges. And a processing distribution device 20.

  Since the basic functions of the two exchanges (for example, call processing function and call processing function) are common, it is not necessary to use different names, but it is better to understand the invention if different names are used. Since it is easy and appropriate, one is referred to as the subscriber information migration source exchange 30 and the other as the subscriber information migration destination exchange 40.

  The call processing distribution device 20 and the migration source exchange 30 or the migration destination exchange 40 can communicate with each other, and the two exchanges 30 and 40 can also communicate with each other regardless of whether the call processing distribution device 20 is routed or not. Communication is possible. Hereinafter, functions of these devices will be described.

  The source exchange 30 is connected to the source subscriber database 31 storing subscriber information, and in addition to the basic functions of the exchange as described above, the subscriber information is transferred to the destination exchange 40 in units of subscribers. A synchronization processing function for performing synchronous communication, a synchronization state management function for managing a progress status of synchronization processing by the synchronous communication, and a synchronization status notification function for notifying the progress status to the call processing distribution device 20 are provided.

  The migration destination exchange 40 has the same functions as the migration source exchange 30. That is, in addition to the basic functions of the exchange as described above, the synchronization processing function for storing the subscriber information transmitted by the synchronous communication with the migration source exchange 30 in the migration destination subscriber database 41, and the synchronization processing by the synchronous communication A synchronization status management function for managing the progress status of the program, and a synchronization status notification function for notifying the call processing distribution device 20 of the progress status.

  As shown in FIG. 1, subscriber information is stored for each subscriber by associating a subscriber telephone number with one or more pieces of subscriber information (for example, forwarding destination) related to the subscriber telephone number. It is managed data. In addition, the synchronization status of the subscriber information performed with the transfer destination exchange 40 is also stored and managed, and the completion is recorded for the subscriber that has performed the synchronization process, and the incomplete is recorded for the unexecuted one. The

  The call processing distribution device 20 has a data management function for updating the call processing distribution determination table in the call processing distribution database 21 based on the progress status of the synchronization processing of the subscriber information notified from the transfer source switch 30 or the transfer destination switch 40. A call processing distribution function for determining a distribution destination of incoming call processing based on the call processing distribution determination table and distributing the call processing to the source exchange 30 or the destination exchange 40.

  As shown in FIG. 1, the call processing distribution determination table is data in which a subscriber telephone number and a call processing distribution destination related to the subscriber telephone number are associated with each other and stored and managed. In this embodiment, the exchange ID of the migration source exchange 30 is A, and the exchange ID of the migration destination exchange 40 is B.

  Note that such a call processing distribution device 20 can be realized by a computer including a storage unit such as a memory and a calculation / control unit such as a CPU, and the functional processing is executed by a program.

  Next, the operation of the subscriber information synchronization system will be described. FIG. 2 is a diagram showing a processing sequence of the subscriber information synchronization system. Before the start of this processing sequence, the synchronization processing between the migration source exchange 30 and the migration destination exchange 40 is not performed, and all the distribution destinations in the call processing distribution determination table are set to A (migration source exchange 30). Suppose that

  Under such conditions, when a call related to the subscriber telephone number “03-XXXX-XXXX” is transmitted from a certain subscriber terminal, the call processing distribution device 20 receives the call via the telephone network 10. Based on the call processing distribution determination table acquired from the call processing distribution database 21, the distribution destination of the incoming call processing is determined as A, and distributed to the source exchange 30 for transmission (step S1).

  Here, when the source exchange 30 starts synchronization processing for the subscriber among a plurality of subscribers included in the subscriber information (step S2), the subscriber information of the subscriber is obtained from the source subscriber database 31. Read and execute synchronization processing with the destination exchange 40 (step S3).

  When the migration source exchange 30 and the migration destination exchange 40 set the synchronization state in each of the databases 31 and 41 to complete for the subscriber (step S4), the migration source exchange 30 A request to change the call processing distribution destination for the user is transmitted to the call processing distribution device 20 (step S5).

  Thereafter, the call processing distribution device 20 changes the call processing distribution destination of the subscriber in the call processing distribution determination table from A to B based on the call processing distribution destination change request transmitted from the source exchange 30. Then, the change completion response is transmitted to the source exchange 30 (step S7).

  Thereafter, when a call is received again from a subscriber terminal of the same subscriber at an arbitrary time point, the call processing distribution device 20 determines the distribution destination of the processing of the incoming call based on the call processing distribution determination table as in step S1. In step S6, since the distribution destination of the incoming call has been changed to B, it is distributed to the destination exchange 40 instead of the source exchange 30 (step S8).

  Thereafter, Steps S2 to S7 are repeatedly executed for each of the synchronization target subscribers, and the call processing is sequentially distributed from the subscriber who has completed the synchronization processing to the destination exchange 40.

  In step S5, the case where the call processing distribution destination change request is transmitted has been described as an example. However, if the call processing distribution device 20 can grasp the completion of the synchronization processing for the target subscriber, the distribution destination can be changed from A to B. It is sufficient to notify the call processing distribution device 20 of the progress status of the synchronization processing from the source exchange 30.

  The telephone network 10 is an example, and may be a PSTN (Public Switched Telephone Network) / IP (Internet Protocol) network, and may be a communication network in general.

  The call processing distribution database 21 may be located inside the call processing distribution device 20. Similarly, the migration source subscriber database 31 may be located inside the migration source exchange 30, and the migration destination subscriber database 41 may be located inside the migration destination exchange 40.

  Further, the call processing distribution device 20 may be degenerated to the migration source exchange 30 and the migration destination exchange 40. Each function of the call processing distribution device 20 may be realized by one functional unit.

  Synchronous communication can be realized by using, for example, FTP (File Transfer Protocol), rsync, an export / import function of a database management system, and the like.

  The call processing distribution destination change request can be transmitted using, for example, SIP (Session Initiation Protocol) MESSAGE, SOAP (Simple Object Access Protocol), DIAMETER / Sh, or the like.

  As described above, according to the present embodiment, when the exchange is divided, the migration source exchange 30 that notifies the progress of the synchronization process performed with the migration destination exchange 40 for the subscriber information is notified. Since the call processing distribution device 20 distributes call processing to one of the two exchanges 30 and 40 based on the progress, the service need not be interrupted for synchronization processing between the two exchanges. It is possible to reduce the influence of the synchronization processing on the exchange processing performance of each exchange 30 and 40. For example, by lowering the priority of the synchronization process over the exchange process of the exchange, it is possible to implement such that the exchange processing performance in each of the exchanges 30 and 40 is not affected.
