Embodiment Construction

[0049] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0050]The technical solutions of the embodiments of the present invention can be applied to a Global System of Mobile communication (GSM for short) system.

[0051] The UE can also be called a mobile terminal (Mobile Terminal, MT), mobile user equipment, etc., and can communicate with one or more core networks via a radio access network (for example, Radio Access Network, RAN). The user equipment can be a mobile Terminals, such as mobile telep...

Abstract

The invention provides an information transmission method, a media gateway and a base station controller. The method comprises: under the condition of IP (internet protocol) conversion of an A interface, receiving DTMF (dual tone multiple frequency) signals sent by user equipment, the DTMF signals comprising button information of the UE (user equipment); converting the DTMF signals into RFC2833 (request for comment 2833) messages, the RFC2833 messages comprising the button information of the use equipment; and sending the RFC2833 messages to the BSC (base station controller) of a BSS (base station subsystem). Since the DTMF signals comprising the button information of the UE are converted into the RFC2833 messages comprising the button information of the user equipment, in the BSS, the button information of the user equipment can be obtained by directly using the BSC to parse the RFC2833 messages, and the operation maintenance of a network is carried out according to the button information of the user equipment, so that the problem of partially failed operation maintenance functions caused by the lack of a transcoder (TC) in the BSS after the conversion of the A interface is solved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of wireless communication, and more specifically, relate to an information transmission method, a media gateway, and a base station controller. Background technique [0002] In a traditional Global System of Mobile Communication (GSM) network, the user plane of the interface (namely the A interface) between the Base Station Subsystem (BSS) and the Media Gateway (MGW) only defines Time Division Multiplex (TDM) transmission mechanism. The only codec under this transport mechanism is Pulse Code Modulation (PCM). The code changer (Transcoder, TC) in the BSS is responsible for completing the voice signal processing from 16kbits to 64kbits. [0003] After the A-interface Internet Protocol (Internet Protocol, IP), the GSM network architecture changes, and the most important change is that the TC resources in the BSS are moved up to the MGW. In this way, the A interface can use code-exci...
