Problems solved by technology

That is to say, in the prior art, users under the failed MSC cannot be distributed to other MSC / MSC servers that work normally in time, so before they are assigned to other MSC / MSC servers that work normally, the original belonging When the user terminal under the faulty MSC is called, the call will fail

Embodiment 1

[0037] In the first embodiment of the present invention, when a certain MSC in the MSC pool fails, it actively initiates a location information request message to a mobile terminal belonging to the failed MSC, and sends a response message of the mobile terminal to the location information request message to On the effective mobile switching center, the effective mobile switching center is triggered to update the location of the mobile terminals under the failed mobile switching center, so that the mobile terminals under the failed mobile switching center can be allocated to other effective mobile switching in time. Instead of passively waiting for the user's mobile terminal to register its location and then distribute the mobile terminal's response message to the effective MSC in the MSC pool, it solves the problem that the user terminal belonging to the failed MSC cannot be called within a certain period of time.

Embodiment 2

[0038] Figure 4 is a flow chart of the second embodiment of the mobile switching center pool fault processing method of the present invention. For the mobile communication system structure shown in Figure 1, the fault processing can be implemented by the method shown in Figure 4. This embodiment Example 2 specifically includes the following steps:

[0039] Step 21: The backup MSC obtains information about the failure of the failed MSC. Due to the VLR data backup relationship between the various MSCs, the backup MSC backs up the VLR data of the failed MSC, and the backup MSC can learn the failure information of the failed MSC according to the backup channel and the status of the signaling point.

[0040] Step 22: The backup MSC initiates a paging message to all mobile terminals belonging to the failed MSC. Since the backup MSC backs up the VLR data of the failed MSC, the location area cells to which all mobile terminals belonging to the failed MSC belong can be known, and paging me...

Embodiment 4

[0055] FIG. 8 is a flowchart of Embodiment 4 of the method for processing a mobile switching center pool failure of the present invention. For the mobile communication system structure in which signaling and bearer are separated as shown in FIG. 2, the method shown in FIG. 8 can be used to To implement fault handling in the MSC pool, the fourth embodiment of the present invention specifically includes the following steps:

[0056] Step 41: The MGW connected to the failed MSC server obtains information about the failure of the failed MSC server. There is an H.248 link between the MGW and the MSC. If the H.248 link fails, the MGW considers that the MSC is down. The failed MSC server in the MSC pool is called the failed MSC server.

[0057] Step 42: The MGW holding the location information of the mobile terminal belonging to the failed MSC server initiates a paging message to all mobile terminals belonging to the failed MSC server. Since one MSC server is connected to multiple MGWs,...

Abstract

The invention relates to a fault-treatment method for mobile exchange central pool, which includes: fault messages of a faulted MSC or MSC server in the mobile exchange central pool are obtained by a fault-treatment device. The fault-treatment device sends a message of location request to a current mobile terminal belonging to the faulted MSC or MSC server, and an access controlling device transmits a message responding to the information of location request from the mobile terminal to an effective MSC or MSC server in the mobile exchange central pool, and the response message triggers the effective MSC or effective MSC server to start a location updating, and the mobile terminal are switched to the effective MSC or MSC server of the mobile exchange central pool. The invention also provides a fault-treatment system for a MSC pool and a fault-treatment device. The invention realizes the mobile terminal belonging to the faulted MSC or MSC server can be distributed to other MSC or MSC server operating normally to have a regular calling.

Description

Technical field [0001] The embodiments of the present invention relate to mobile communication technologies in the communication field, and in particular to a method, device, and system for troubleshooting in a mobile switching center (Mobile Switch Center, MSC for short) pool. Background technique [0002] Figure 1 is a schematic diagram of the structure of a mobile communication system based on the MSC pool in the prior art. The MSC access control equipment is used in the Global System for Mobile Communications (Global System for Mobile Communications, GSM) and multiple code divisions. In the Code Division Multiple Access (Code Division Multiple Access, CDMA) system, the access control equipment is a base station controller (Base Station Control, BSC); in the Wideband Code Division Multiple Access (Wideband Code Division Multiple Access) In a wideband code division multiple access (WCDMA) system, the access control device is a radio network controller (Radio Network Controller,...
