Method and apparatus for bearing voice call, and mobile terminal

Abstract

The invention provides a method and an apparatus for bearing a voice call, and a mobile terminal. The method comprises the steps of after a terminal establishes a voice call, starting to time from a moment at which the voice call is established, and detecting whether a network to which the terminal is registered at present establishes a voice bearer or not successfully; when detecting that the network does not establish the voice bearer successfully at the end of a first predetermined time, starting, from a moment when the first predetermined time is ended, to adopt an IMS default bearer to transmit data generated by the voice call till that the network establishes the voice bearer successfully is detected, wherein a time of detecting that the network establishes the voice bearer successfully is not greater than a second predetermined time; and after detecting that the network establishes the voice bearer successfully, adopting the voice bearer to transmit the data generated by the voice call. According to the method and the apparatus, for a terminal not supporting a resource reservation mechanism, the voice call can be kept normally before the voice bearer is established, and thusthe user experience is improved.

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...

AI Technical Summary

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.
