Problems solved by technology

[0003] Therefore, when a VOLTE voice call is made on a network that supports the VOLTE function, it comes to a new TA (Tracking area, tracking area) network that does not support the VOLTE function, and the terminal obtains the support capability of the network as After not supporting VOLTE, the terminal may directly disconnect the voice call link with the network, or keep the link but cannot guarantee the voice service, such as no sound or poor call quality
In addition, if a cell switch occurs when the terminal initiates or hangs up a VOLTE call, the terminal transmits signaling on the original cell and the terminal has arrived at the new cell when the network responds, and cannot receive the signaling and needs to be retransmitted, resulting in call delay

Embodiment Construction

[0037] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0038] Such as figure 1 As shown, the terminal in the embodiment of the present invention includes: a network monitoring module, a bearer monitoring module, and a call processing module, wherein,

[0039] The network monitoring module is used to monitor whether the terminal is switched from a VOLTE network to a non-VOLTE network during a call, mainly to detect whether the terminal moves to a non-VOLTE cell and whether there is a risk in the voice call.

[0040] The bearer monitoring module includes: a bearer list update submodule and a bearer change monitoring submodule, mai...

Abstract

The present invention provides a voice call method and terminal. The method includes: monitoring the terminal to switch from a VOLTE network to a non-VOLTE network during the call; using a designated bearer on the network to transmit voice service information, or monitoring when the bearer changes. , reselect the bearer to transmit voice service information. The invention can ensure the call security of the VOLTE terminal, that is, no call drop after switching from the VOLTE network to the non-VOLTE network and ensuring the call quality.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and terminal for voice communication. Background technique [0002] With the development of LTE (Long Term Evolution, long-term evolution system) network, voice solutions under LTE network mainly include the following types: CSFB (CSFallback, circuit domain fallback), single card dual standby and VOLTE (based on IMS (IPMultimedia Subsystem , the voice service of IP Multimedia Subsystem), wherein, VOLTE is the real voice solution of LTE network. As for whether a network supports VOLTE, the terminal is notified through network signaling. If it does not support it, the terminal cannot perform VOLTE services under the network. [0003] Therefore, when a VOLTE voice call is made on a network that supports the VOLTE function, it comes to a new TA (Tracking area, tracking area) network that does not support the VOLTE function, and the terminal obtains the support capability of the ne...
