Problems solved by technology

However, this framework also brings about a problem. Since the BSC cancels the TC, the TC function of the MGW is used during the call. Therefore, there is a need for a method to enable the voice codec between the core network and the wireless network before the call is established. Negotiation of functions to avoid the core network from assigning the voice version that the wireless network cannot provide
Otherwise, when the core network assigns a voice version that cannot be provided by the wireless network, the MGW has to insert a TC for voice adaptation when processing a call, which wastes TC resources and cannot establish Trfo during the call.

Embodiment Construction

[0024] In the GSM communication system, when the A interface is based on IP bearer, the network structure is as shown in Figure 1, including: mobile terminal 60, base station 50, base station controller 20, media gateway 30, mobile switching center server 10 and mobile terminal 60 Um interface between base station 50, Abis interface between base station 50 and base station controller 20, base station controller 20 and media gateway 30, A interface between mobile switching center server 10, mobile switching center server 10 and media gateway Mc interface between 30. The TC 40 is canceled from the BSC 20, and the TC 40 in the MGW 30 is used to complete the voice rate adaptation function after the call is established.

[0025] As shown in Figure 2, the present invention reuses two BSSAP messages in the existing protocol, namely the resource request message RESOURCE REQUEST and the resource indication message RESOURCE INDICATION, and makes the base station subsystem Base Station ...

Abstract

The present invention relates to a method of realizing the interaction of voice coding and decoding capacity between the wireless network and the core network. The present invention includes: MSC Server (10) sends the expanded request information of BSSAP resource to BSC (20) and requires BSC (20) to report the voice coding capacity of all plots under management and BSC (20) reports the voice coding capacity of all plots to MSC Server (10) through a plurality of expanded resource indication information. Through the method, MSC Server (10) is able to know the voice coding capacity of all plots on the wireless network, thus avoiding the fact that the wireless network allocated by the core network can not provide the voice version, further reducing the number of voice coding and decoding, easily achieving the conversion operation of non-voice coding and decoding and improving the voice quality.

Description

technical field [0001] The invention relates to a mobile communication system, in particular to a method for realizing the interaction of voice coding and decoding capabilities between a wireless network and a core network. Background technique [0002] In the existing Global System for Mobile Communications (GSM for short), the A interface between the Mobile Switching Center (MSC for short) and the Base Station Controller (BSC for short) is based on time division multiplexing Time Division Multiple, referred to as TDM bearer, transmits 64Kbps Pulse Code Modulation, referred to as PCM voice coded signal. Compressed speech coded signals are transmitted on the air interface Um interface between the mobile terminal MobileStation, referred to as MS and the base station Base Station, referred to as BTS. The interface between the BTS and the BSC is the Abis interface, which is also based on TDM bearer, and what is transmitted on this interface is the same compressed speech coded ...
