Problems solved by technology

During the process of the terminal device falling back from the NR network to the LTE network, the terminal device needs to perform a tracking area update (TAU). During the TAU process, the terminal device cannot create a dedicated voice bearer under the LTE network, making voice calls failure, resulting in less reliable communication

Abstract

The embodiment of the present application provides a communication method, device, and equipment, the method includes: in the tracking area update TAU process, the terminal device receives the dedicated bearer establishment request sent by the network device through the second network, and the TAU process is used for all The terminal device falls back from the first network to the second network; the terminal device establishes a voice-specific bearer according to the dedicated bearer establishment request, and the voice-specific bearer is used for the terminal device on the second network Perform voice services on the network.

Description

technical field [0001] The embodiments of the present application relate to the field of communication technologies, and in particular, to a communication method, device, and equipment. Background technique [0002] A terminal device (for example, a mobile phone, a tablet computer, etc.) may access a new radio (new radio, NR) network, or may access a long term evolution (long term evolution, LTE) network. [0003] When the terminal device is on the NR network, if the terminal device has voice service requirements, the terminal device can fall back from the NR network to the LTE network, and perform voice services on the LTE network. During the process of the terminal device falling back from the NR network to the LTE network, the terminal device needs to perform a tracking area update (TAU). During the TAU process, the terminal device cannot create a dedicated voice bearer under the LTE network, making voice calls failure, resulting in poor communication reliability. Cont...
