Voice call bearing method, device and mobile terminal

Abstract

The present invention provides a voice call bearing method, device and mobile terminal. The method includes: after the terminal establishes a voice call, counting time from the time when the voice call is established, detecting whether the network currently registered by the terminal successfully establishes a voice bearer, and when it is detected that the network fails to establish a voice bearer after the first predetermined time bearer, starting from the end of the first predetermined time, using the IMS default bearer to transmit the data generated by the voice call until it is detected that the network successfully establishes a voice bearer, wherein the time for detecting that the network successfully establishes a voice bearer does not exceed Second predetermined time: after detecting that the network has successfully established a voice bearer, using the voice bearer to transmit data generated by the voice call. For a terminal that does not support the resource reservation mechanism, the present invention can keep the voice call normal before the voice bearer is established, thereby improving user experience.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a voice call bearing method, device and mobile terminal. Background technique [0002] In 3GPP Long term evolution (Long term evolution, LTE), with the explosion of data services and the all-IP network, a VoLTE technology is proposed for the voice solution in LTE. VoLTE is an IP data transmission technology. All services are carried on the LTE network, which can realize the unification of data services and voice services on the same network. That is to say, the LTE network can not only provide high-speed data services, but also provide high-quality voice calls in combination with VoLTE technology. [0003] In the existing VoLTE voice call establishment process, VoLTE terminals (including the calling terminal and the called terminal) usually support the resource reservation mechanism, so when the VoLTE voice call is established, the voice bearer between the VoLTE...

Problems solved by technology

[0004] However, the resource reservation mechanism is not a mandatory function for VoLTE terminals. For VoLTE terminals that do not support the resource reservation mechanism, there will be a certain delay in the establishment of the voice bearer compared to the establishment of the voice call. That is to say, When the VoLTE voice call is connected, the voice bearer is not ready, and the voice call data cannot be transmitted at this time. The voice call data can only be transmitted normally after the voice bearer is ready. During this delay time, the call is silent, which affects the user experience.
