Problems solved by technology

But this method also has disadvantages, because firstly, the T3105 timer is usually set not long, and there is little room for compression; secondly, PhyInfo needs to be sent on the Fast Associated Channel (FACCH) by stealing frames, and frequent sending times will also affect the downlink voice quality. influences

Embodiment Construction

[0037] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0038] refer to image 3 , is a flow chart of an embodiment of a method for improving speech perception during switching in the GSM system of the present invention. Such as image 3 As shown, the method includes the following steps:

[0039] Step S10, after the base station receives the Handover Access sent by the mobile communication terminal, it feeds back the physical information PhyInfo to the mobile communication terminal, and simultaneously starts the detection of the downlink voice; in the present invention, the mobile communication terminal can be a mobile phone, and the base station is equipped with The downlink voice detection module, after the base station receives the uplink handover access handover access sent by the mobile phone, when it feeds back the physical information PhyInfo to the mobile phone, ...

Abstract

The invention discloses a method for improvement of voice perceptibility in a handover process in the global system for mobile communications (GSM). The method comprises the steps that a base station feeds back PhyInfo to a mobile communication terminal after receiving HandoverAccess sent from the mobile communication terminal and carries out detection on downlink voice; the PhyInfo is used for replacing replaceable voice frames according to a replaceable voice frame detection result of the downlink voice; and transmission of the PhyInfo is stopped when an SABM frame sent by the mobile communication terminal is received or the number of times of transmitting reaches to the biggest value Ny1. The invention further discloses a base station and a system for the improvement of the voice perceptibility in the handover process in the GSM. According to the method, the base station and the system for the improvement of the voice perceptibility in the handover process in the GSM, the voice perceptibility can be improved.

Description

technical field [0001] The invention relates to the field of wireless communication, and more particularly relates to a method, a base station and a system for improving voice perception during switching in a GSM system. Background technique [0002] In GSM (Global System of Mobile communication, Global System for Mobile Communications), in order to improve the user's perception of voice calls, it is necessary to handover (HandOver, HO) to a relatively good wireless signal quality when the quality of the wireless channel is degraded or in other cases. cell to improve voice quality. Taking asynchronous switching as an example, the general switching process is as follows figure 1 Shown: [0003] The network side sends a handover command (HandOver Command, HOCMD) on the original channel (BTS1); after receiving it, the mobile phone sends a handover access (HandOverAccess) on the designated target channel (BTS2), and the target channel base station (BTS2) receives the HandOver ...
