Problems solved by technology

However, after the A interface uses the IP protocol to transmit voice, the TC moves up to the Media Gateway (MGW), and the A interface only transmits valid frames. When the TAF is 1, the base station may not receive the A interface. Valid frames, resulting in no frames to send at this moment, the base station can only turn off the power or send filling frames, which affects the voice quality or the downlink measurement of the mobile phone

Embodiment Construction

[0019] In the method described in the following embodiments, the A interface uses the IP protocol to transmit the voice service between the base station and the core network, and uses the standard RTP protocol to encapsulate the voice. In the embodiment of the present invention, the local base station detects the received service frame sent by the remote base station. The service frame includes at least a speech frame or a SID frame, and judges whether the service frame contains continuous speech frames. If it contains continuous speech frame, the base station at the local end sends continuous voice frames to the MS in the normal transmission mode; otherwise, the downlink transmission mode is determined to be DTX mode, and the service frame is sent, and at the same time, it is judged whether the service frame contains a SID frame, when the service frame contains a SID frame , the local base station stores the latest SID frame; when the downlink TAF is 1 and no voice frame is re...

Abstract

The invention discloses a method for sending service frames, which comprises the following steps: a home terminal base station receives the coming service frame; and the home terminal base station stores the SID frame when the service frame includes a mute-described SID frame, and the home terminal base station sends the latest stored local SID frame when that no voice frame is sent at the pre-set time is determined. By applying the method provided by the embodiment of the invention, the latest local SID frame stored in the base station can be sent even when no voice frame is sent at the timethat the downlink TAF is 1 when an interface A carries out the voice transmission by utilizing an IP protocol, thereby solving the problems that MS downlink measurement is incorrect and the mute can not be recovered timely.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a method and device for sending service frames. Background technique [0002] The GSM system (Global System for Mobile Communication, digital cellular mobile communication system) was developed in accordance with the GSM specification formulated by the European Telecommunications Standards Institute (ETSI), and is the second generation of mobile communication technology (Second Generation, 2G). The purpose of its development is to allow all parts of the world to use a common mobile phone network standard, so that users can travel all over the world with a single MS. The GSM communication system is mainly composed of three parts: Mobile Switching Subsystem (MSS), Base Subsystem (BSS) and Mobile Station (MS), among which the interface between MSS and BSS is A interface , the interface between the BSS and the MS is the Um interface (usually called the air inter...
