Embodiment Construction

[0031] The inventors of the present application found that some operator networks do not support CSFB (Circuit Switched Fallback) function when deploying LTE network, but support VoLTE (Voice Over LTE) service, that is, LTE voice call. If a VoLTE terminal initiates a combined ATTACH / TAU, no matter whether the registration is successful or not, the CSFB will not be available, and the joint registration will still be initiated later, which causes a waste of signaling and greatly increases the network burden.

[0032] In the embodiment of the present invention, by querying the network identification list stored in the terminal, it is judged whether the registered target network supports circuit domain fallback. When the target network does not support circuit domain fallback, the first type of registration is initiated to the target network; if the If the network identifier of the target network is not included in the network identifier list, registration is initiated to the targe...

Abstract

The invention relates to a VoLTE terminal registration method and device. The VoLTE terminal registration method comprises the steps of querying a network identifier list stored in a terminal before registration is initiated to a target network, wherein the network identifier list records network identifiers which do not support circuit domain fallback; initiating a first type of registration to the target network if the network identifier list contains a network identifier of the target network; and initiating registration to the target network if the network identifier list does not contain the network identifier of the target network. The method and the device provided by the invention can effectively reduce consumption of signaling resources, simplify the registration process and improve the registration efficiency.

Description

technical field [0001] The present invention relates to the communication field, in particular to a VoLTE terminal registration method and device. Background technique [0002] LTE is a wireless data communication technology standard. It uses new technologies and modulation methods to improve the data transmission capacity and data transmission speed of wireless networks, and provides users with better data services. It is regarded as the mainstream technology in the evolution from 3G to 4G. At present, LTE has been supported by many mainstream operators in the world, and my country has officially started commercial use of LTE networks. [0003] Some LTE networks can support the VoLTE function, but the network registration efficiency and resource utilization of VoLTE terminals need to be improved. Contents of the invention [0004] The technical problem solved by the invention is to improve the network registration efficiency and resource utilization rate of VoLTE termina...
