Abstract

The invention discloses a method and device for improving a VoLTE call success rate, and a storage medium. The method comprises the following steps: when a mobile terminal resides in a long term evolution LTE network, receiving a voice incoming call of a circuit switch CS domain of a network side; executing circuit domain drop CSFB processing, establishing a voice call in the network that can process the CS domain voice call, and sending a message of cancelling VoLTE service to the network side after the voice call is ended. According to the method and device, after the CSFB call is ended, if there is no voice service, the message of cancelling the VoLTE service is sent to the network side, therefore the cancellation success rate can be effectively guaranteed, and the VoLTE registration states of the terminal and the network side are consistent, thereby effectively avoiding the situation of call failure caused by the inconsistent states of the terminal during the VoLTE registration and improving the call success rate.

Description

technical field

[0001] The present invention relates to the field of network communication, in particular to a method, device and storage medium for improving the success rate of VoLTE calls. Background technique

[0002] VoLTE (Voice over LTE, voice long-term evolution) is an end-to-end voice solution based on the full Internet protocol on the 4G network, and it is the ultimate solution for voice in the LTE era. For operators, the deployment of VoLTE not only improves wireless spectrum utilization and reduces network costs, but also introduces services such as high-definition video telephony and high-definition voice, which significantly improves communication quality.

[0003] The voice service under the 4G network is performed based on the PS (Packet Switch, packet switching) domain. However, due to reasons such as coverage and capacity in the actual network, the following phenomenon sometimes occurs: when the mobile terminal resides on the 4G network and the VoLTE regis...
