Abstract

The embodiment of the invention discloses a communication terminal dwelling network switching method and a communication terminal. The method includes the following steps that: a communication terminal detects whether a triggering event of call communication services occurs; if the communication terminal detects a triggering event of call communication services, the communication terminal obtains the signal strength value of a first network where the communication terminal dwells currently; if the communication terminal detects that the signal strength value is smaller than a preset signal strength threshold value, the dwelling network of the communication terminal is switched from the first network to a second network, and the second network carries voice call communication services triggered by the triggering event of the call communication services. With the method provided by the technical scheme provided by the embodiment of the invention adopted, voice stagnation or communication interruption caused by network switching which is dominantly controlled by a network side in a call communication process can be avoided, and therefore, call communication experience of a user can be enhanced.

Description

technical field

[0001] The invention relates to the field of communication technology, in particular to a communication terminal resident network switching method and a communication terminal. Background technique

[0002] The realization goal of LTE (LongTermEvolution, the long-term evolution of general mobile communication technology) is to provide better data services, but it only realizes the PS domain (data domain), but does not realize the CS domain (voice domain), that is, when the terminal resides When on the LTE network, if the user initiates or receives a voice call, the terminal will fall back from the LTE network to the 2G / 3G network, and the voice domain of the 2G / 3G network will provide the voice service, and return to the LTE network to reside after the voice service ends. VOLTE (Voice over LTE, 4G voice service) is a voice service based on the LTE network. Voice data packets are transmitted through the PS domain of LTE, and voice services are provided without...
