Communication control method, terminal, network side equipment and network switching system

Abstract

The invention provides a communication control method, a terminal, network side equipment and a network switching system. The communication control method used to control communication network switching of the terminal in conversation comprises that a signal-to-noise ratio of a first network to which the terminal is connected is obtained; when the signal-to-noise ratio is lower than a preset threshold, a switching triggering event for triggering network switching is output to the network side equipment; and the terminal is switched to the second network whose network mode is different from that of the first network. According to the invention, the network switching threshold can be adjusted in real time, so that the terminal can be switched to the 2G network timely and continue conversation when 3G network signals is worse, and better user experience is provided.

Description

technical field [0001] The present invention relates to the technical field of communication, and in particular to a communication control method, a terminal, a network side device and a network switching system. Background technique [0002] In the prior art solution, when calling under the 3G (Third Generation, third-generation mobile communication technology) network, the network configuration switches to the threshold of the 2G (2-Generation wireless telephone technology, second-generation mobile phone communication technology specification) network If the value is very high, the terminal will switch to the 2G network only when the signals of the 2G / 3G network measured by the terminal meet the threshold at the same time. In this way, when the signal of the 3G network is very poor, the terminal cannot switch or the speed of switching to the 2G network is slow, resulting in dropped calls or intermittent sound, affecting user experience. [0003] In addition, in the TD-SCD...

This will cause when the 3G network signal is very poor, the terminal cannot switch or the speed of switching to the 2G network is slow, resulting in dropped calls or intermittent sound, affecting user experience

[0003] In addition, in the TD-SCDMA (Time Division-Synchronous Code Division Multiple Access, Time Division Synchronous Code Division Multiple Access) protocol, RSCP (Received Signal Code Power, received signal code power) is generally used as the handover decision condition for handover from the 3G network to the 2G network, and The interference ratio Ec / Io is not included in the handover decision condition
