Problems solved by technology

[0022] Obviously, after the connection is established, the communication between users will always occupy the inter-office channel resources between the two MSCs. This calling method has caused a shortage of inter-office channel resources.

Embodiment Construction

[0040] The call flow under the BSC multi-homing networking in the embodiment of the present invention includes the following steps: the calling user initiates the call, the calling mobile switching center MSC / visitor location register VLR extracts the called MSC identity from the message returned by the home location register HLR , Determine that the calling and called MSC belong to the same BSC multi-homing resource pool, obtain the called user data, initiate intra-office calls, and establish intra-office call connections.

[0041] In the embodiment of the present invention, a resource pool data table is added to each MSC in a BSC multi-homed resource pool to record information about other MSCs belonging to the same BSC multi-homed resource pool as the current MSC. Assuming that the BSC1 of the calling user MS1 and the BSC2 of the called user MS2 belong to the same BSC multi-homing resource pool, the signaling flow of the interoffice call between the calling user MS1 and the call...

Abstract

This invention discloses a method of call in a BSC network. It includes the following steps: the Caller initiates calls, calling mobile switch center MSC / visits location register VLR, extracts MSC logo from the news of the Home Location Register HLR, judges whether caller and called of MSC is the same BSC pool of resources, extracts the data of called, initiates calls in the council, and establishes call connection in the council. The present invention also discloses a call device in the BSC network. For the ordinary calls, if the user of caller and called in the same BSC multi-user network, using the device can change among the call for within the call to save the road resources between in the council.

Description

Technical field [0001] The present invention relates to the field of communications, in particular to a calling technology under BSC multi-homing networking. Background technique [0002] Usually, a base station controller (Base Station Contral, BSC) can only be connected to a mobile switching center (Mobile Switching Center, MSC), such as figure 1 As shown, if a user registered under MSC1 wants to communicate with a user registered under MSC2, he must go through the connection between MSC1 and MSC2 to make an interoffice call. What needs to be clear is that a VLR (Visitor Location Register) usually serves an MSC, and the VLR of the existing network equipment is usually embedded in the MSC. Therefore, sometimes MSC and VLR are written together as MSC / VLR. [0003] Such as figure 2 As shown, the BSC multi-homing networking means that one BSC can be connected to multiple MSCs. The BSC distributes services to each MSC for processing through a certain algorithm, and realizes load s...
