Problems solved by technology
[0016] It can be seen that the existing A interface circuit management is mainly completed by MSC Server. Due to the large number of MSC Servers in the mobile communication network, the management is relatively complicated.
And, usually in the MSC pool (MSC Pool) networking structure where bearer and control are separated, each MSC Server in the MSC Pool is respectively connected to each virtual media gateway (VMGW, Virtual Media GateWay) in the same MGW, and a MGW Any specified A interface circuit between the BSCs connected to it can only belong to one MSC Server and cannot be shared by all MSC Servers, and the reuse rate of the A interface circuit is low; In this case, it is necessary to add A interface circuit resources through data configuration, or transfer a part of A interface circuit resources from other MSC Servers to the newly added MSC Server, which will increase the complexity of A interface circuit operation and maintenance.

Embodiment Construction
[0057] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.
[0058] The basic idea of the present invention is: the A interface circuit management function is moved down from the MSC Server to the MGW, and the A interface circuit management is completed by the MGW.
[0059] Taking the allocation and release of the A interface circuit in the call process as an example below, the A interface circuit management of the present invention is described in detail, as shown in Figure 2, this embodiment mainly includes the following steps:
[0060] Step 201: UE initiates a call or receives a call.
[0061] Step 202: When the UE initiates or receives a call, the MSC Server sends a circuit resource allocation request to the MGW, requesting the MGW to allocate an A interface circuit for the UE, and the circuit resource allo...

A A-access circuit management method is provided in the present invention, its basic idea is: to shift A-access circuit management function down to the MGW from the mobile switching center server MSC Server, finishing A-access circuit distribution and release by MGW. A A-access circuit management system is also provided in the present invention, comprising a MGW and a MSC Server. Furthermore, a MGW is also provided in the present invention, mainly comprising a dispatching unit and a distributing unit. The present invention can decrease the complexity of the A-access circuit management; and in the special network structure, it can also realize A-access circuit resource share, improve the reuse rate of the A-access circuit, and decrease the complexity of A-access circuit maintenance.
Description
technical field [0001] The present invention relates to mobile communication technology, in particular to an A interface circuit management method, system and media gateway in a mobile communication network in which bearer and control are separated. Background technique [0002] In the mobile communication network where bearer and control are separated, the mobile switching center (MSC, MobileSwitch Center) is divided into two parts: the mobile switching center server (MSC Server) and the media gateway (MGW, Media Gateway). In this network, the A interface circuit Management is mainly completed by MSC Server. [0003] Figure 1 is a schematic diagram of the allocation and release process of the A interface circuit during the call process, which mainly includes the following steps: [0004] Step 101: a user equipment (UE, User Equipment) initiates a call or receives a call. [0005] Step 102: Through the A interface circuit management function, the MSC Server allocates an A ...
