DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the related art, when a user roams to another city and accesses the service system of the roaming city, different external access codes are needed to trigger the service system, thereby bringing the user a pole. The big trouble is not conducive to improving the user experience. Therefore, the present invention provides a technical solution for setting a unified external access code, and setting a set of service systems locally and in the field, and the user accesses the service system of the user's location by dialing a unified external access code. Since the internal access code of each area is stored in the service system, and the internal access code is opaque to the user, the service system can redirect the user-initiated call to the corresponding service according to different internal access codes. The system processes it. The above technical solutions will be described in detail below. The preferred embodiments of the present invention are described in the following with reference to the accompanying drawings, which are intended to illustrate and illustrate the invention. System Embodiment According to an embodiment of the present invention, a service system is provided. The following is an example in which a service system is set up in two places, but the present invention is not limited thereto, and may be extended to be set in each of a plurality of regions. Set of business systems. 1 is a block diagram of a service system of an embodiment of the system of the present invention. As shown in FIG. 1, the service system includes a database 10, an access processing module 12, a service processing module 14, and a media processing module 16, and the following modules are performed. Detailed explanation. The database 10 is connected to the service processing module 14 and configured to store a unified external access code, local user information, and local and foreign redirection information. The redirection information stored in the database 10 includes at least one of the following:

(1) Site information of local and foreign business processing modules.

(2) Local and foreign user address information, correspondence between local and foreign user address information and site information of the service processing module, for example: address information of the user in area A corresponds to site information in area A, and address information of user in area B corresponds to Site information to the B area.

(3) Local and foreign internal access codes, the internal access code is opaque to the user, and different internal access codes are required in each place. The access processing module can send the call to the corresponding service processing according to different internal access codes. The module processes it. The access processing module 12 is connected to the service processing module 14 and configured to receive a call initiated by the user by dialing a unified external access code, and analyze the number of the calling user (in which the number of the calling user number is mainly analyzed) And the access code (external access code and internal access code) is processed to obtain the address information (number header information) of the user, and establish a communication channel with the local service processing module and the foreign service processing module, and establish a channel The user's address information is sent to the service processing module 14 via a predetermined message (sip invite). For example, the access processing module of area A needs to analyze the external access code XXX and the internal access code yyy to point to the service processing module of area A, analyze the internal access code zzz to point to the service processing module of area B; and access processing of area B The module needs to analyze the external access code XXX and the internal access code zzz to point to the service processing module of the B area, and analyze the internal access code yyy to point to the service processing module of the A area. The service processing module 14 can also be used to complete the service flow control of the entire service system, and determine the home location service of the user according to the address information (number header information) of the user sent by the access processing module 12, local and foreign redirect information. system. After the service processing module 14 determines that the user's home service system is the foreign service system, the access processing module 12 sends a redirect request message (sip invite message) to the user's home service system according to the redirect information. In addition, the foregoing system may further include: a media processing module 16 configured to implement processing on the media file, where the media file includes a service for playback, receiving, recording, and faxing. With the above technical solution, the user can access the local service system by dialing a unified external access code. After the local service system performs corresponding analysis, the redirect request message is sent to the service system of the user's home location. The service system at the home base analyzes the received redirect request message and performs corresponding processing. In the local service system, the access processing module 12 is further configured to receive the redirection sent by the access processing module in the foreign service system. Request the message and forward it to the local business processing module. After receiving the redirect request message, the service processing module 14 queries the user information of the user in the local database according to the redirect request message, and controls the media processing module to perform corresponding processing according to the user's operation. In this way, when the foreign service system sends a redirect request message, the redirect request can be cancelled. The information is processed, and the corresponding processing is performed for the user's operation. In addition, in the case that the local media processing module is faulty or the user is overloaded, the transfer module in the service system can transfer the user information of some or all users in the local database to the predetermined foreign database; and, the configuration module is The correspondence between the user address information of some or all users and the site information of the predetermined foreign service processing module is configured in the local database. For example, when there are too many users in the A area and there are fewer users in the B area, some of the user data in the area can be transferred to the database in the B area for storage, and the site information of the user in the database A is assigned to The business processing module of Area B is processed. Or, during the running of the system, the media processing device in Area A is abnormal and cannot be recovered in a short time. The user data of the area A can be transferred to the database of the area B for storage, and the site information of all the users of the area A is configured in the database A to be processed by the service processing module of the area B, and the service is completed by the media processing equipment of the area B. The processing functions of media files such as playback, receiving, recording and faxing. In this way, after the user accesses the local service system through the unified external access code, the service processing module determines that the user has belonged to the predetermined foreign service processing module site processing, and can forward the call of the user to the corresponding service processing. The module processes it. Through the above processing, users who use the service system for different regions can use the same access code to access the system whether they use the service at the home location or use the service after roaming to another place. It is convenient for the user, so that the user does not need to dial the area code to access the home system after roaming. And the load sharing between the systems in the two places and the disaster tolerance of the media processing equipment are realized. The method embodiment of the present invention provides a call redirection method, which can be applied to the service system of the system embodiment of the present invention. FIG. 2 is a flowchart of a call redirection method according to an embodiment of the present invention.

Step S204: After the local service system receives the call initiated by the user by dialing the unified external access code, the local service system determines the user's home service system according to the user number, local and foreign redirect information. The specific processing of step S204 is: the service system queries the user address information according to the external access code and the user number, and determines the service of the user's home location according to the correspondence between the local and foreign user address information and the site information of the service processing module. system. Step S206: After determining that the user's home service system is a foreign service system, the redirect request message is sent to the user's home service system according to the redirect information. The above redirect request message is a session initiation protocol based redirect request message. After determining the service system of the user's home location, the specific process of step S206 is: sending a redirect request message to the user's home business system according to the correspondence between the local and foreign user address information and the site information of the service processing module, The redirect message carries an internal access code of the user's home service system. In addition, after step S206, the service system located at the user's home location responds to the redirect request message, and after processing the internal access code in the redirect request message, the service of the redirect request message at the user's home location is processed. The user information of the user is queried in the database of the system, wherein the user information of the user's home database stores the user information of the user's home location, the user's home location, and the foreign domain redirection information; the service system of the user's home location is based on the query. User information and user operations are processed accordingly. Through the foregoing processing, the user accesses the system by using a unified external access code. After determining the user's home service system, the service system transfers the user to the service system of the home location for processing. In addition, in the case that the local service system is overburdened or the media processing module is faulty, the user information of some or all users in the local database may be transferred to a predetermined foreign database, and a part or The correspondence between the user address information of all users and the site information of the predetermined foreign service processing module. In this way, after the local user accesses the local service system, the local service system transfers the local user to the foreign service system, so that the foreign service system replaces the local service system to process the local user, thereby realizing the load sharing and capacity of the business system between different regions. Disaster function. The technical solutions of the foregoing system embodiments and method embodiments are exemplified in the following with reference to the accompanying drawings. In the example 1, the local service system redirects the call of the user B to the service system of the user's home B. In this example, the structure of the supporting system is as shown in FIG.
