Intra-MSC A-Flex is also called Mini-A-FLEX. Normally, the MSOFTX3000 is only connected to GSM BSCs that belong to the same MGW. If the MGW that the BSCs belong to is faulty, the services handling by these BSC will be interrupted. To avoid the service failure caused by the MGW upgrade or MGW failure, Mini-A-FLEX is introduced to allow one BSC to connect to multiple MGWs.

 

These MGWs adopt the load sharing mode for service management. When one MGW is faulty, other MGWs can take up the load. Meanwhile, to save the trunk transmission resource to the maximum extent, the circuit connections between MGWs under the same MSC system are reduced. When the calling and called BSCs are connected to the same MGW, the system selects the shared MGW first .

 

Mini-A-FLEX networking needs to implement the following system functions:

 

• A BSC can be connected to multiple MGWs. The MSOFTX3000 can select the circuit resource of the corresponding MGW based on the requirements.
• When the calling and called BSCs are connected to the same MGW, the system selects the circuit on the same MGW first to avoid wasting the circuit resource between MGWs.
