Method, device and terminal for volte network registration

Abstract

The invention relates to the field of communication technologies, and in particular, to a method and an apparatus for VoLTE network registration, and a terminal thereof. The VoLTE network registration method includes: the signal strength supporting a VoLTE network frequency band is obtained; when the obtained signal strength is within a preset threshold range, the network searching priority of the terminal to the VoLTE network frequency band is increased; and a VoLTE network is registered according to the network searching priority. In addition, a VoLTE network registered device is also provided. The device comprises a signal strength acquisition module for obtaining the signal strength supporting the VoLTE network frequency band, a judging module for judging whether the acquired signal strength is within the preset threshold range, a priority processing module for adjusting the network searching priority, and a network registration module. The method improves the success rate of VoLTE network registration and enables users to enjoy high-speed data services and high-quality audio and video calls as much as possible.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, device and terminal for VoLTE network registration. Background technique [0002] VoLTE is Voice over LTE. It is an IP data transmission technology that does not require 2G / 3G networks. All services are carried on 4G networks, which can realize the unification of data and voice services under the same network. In other words, the 4G network not only provides high-speed data services, but also provides high-quality audio and video calls, which require VoLTE technology to achieve. [0003] At present, due to the fact that the commercial use of VoLTE has not been fully launched, some terminals require users to turn on the 4G call switch. On the other hand, the VoLTE function is not supported by all operators in the world, but only a small number of operators support it, and only some frequency bands support VoLTE. Therefore, in the actual use process, somet...

Problems solved by technology

Therefore, in the actual use process, sometimes the terminal cannot register the VoLTE network, and sometimes it can register the VoLTE network.

[0004] As far as the use of the VoLTE-supporting SIM card of the British operator H3G fails to register for VoLTE, the reason is caused by the network. When the signal strength of the VoLTE network does not meet the standard or other reasons cause the registration of the VoLTE network to fail At this time, the LTE of the mobile phone will reside in the frequency band of other networks, and due to the settings of the terminal system, the system will no longer search for the frequency band corresponding to the VoLTE network. As a result, even if the signal strength of the VoLTE network meets the requirements later, the user still cannot register. VoLTE network, resulting in low registration success rate of VoLTE network
