Problems solved by technology

[0004] The main idea of ​​CSFB technology is the fourth generation of mobile communication (4 th -generation, 4G) terminal equipment resides in the LTE network, and when initiating a voice service, it completely falls back to the second mobile communication (2 nd -generation, 2G) or the third generation of mobile communication (3 rd -generation, 3G) network, and then conduct voice services through the circuit switch domain (CS domain) in the 2G or 3G network, and pass through the packet switch domain (PS domain) in the 2G / 3G network before continuing in the LTE network Unfinished data services, but the rate of data services will be significantly reduced, or even interrupted

Abstract

An embodiment of the present application provides a communication method and device thereof, wherein the method may include the following steps: a terminal device receives a first message from a first access network device, and the first message is used to notify the terminal device to divide the antenna into the first antenna The first antenna group is used to access the circuit domain, and the second antenna group is used for data services; the terminal device accesses the circuit domain through the first antenna group, and performs data services through the second antenna group. By adopting the embodiment of the present application, it is expected that in the 5G network and subsequent mobile communication networks, when the terminal device initiates the voice service, it can support the voice service and the data service at the same time.

Description

technical field [0001] The embodiments of the present application relate to the field of communication technologies, and in particular to a communication method and device thereof. Background technique [0002] At present, in the communication system, there are mainly three technologies for carrying voice services: voice service fallback (circuit switch fallback, CSFB), single card dual standby, and long term evolution (long term evolution, LTE) transmission of voice (voice over LTE, VoLTE). ). Among them, CSFB and VoLTE belong to the network side solution, and single card dual standby belongs to the terminal side solution. [0003] When a terminal device (such as user equipment (UE)) resides on an LTE network, when the terminal device initiates a voice service (including calling and called), the CSFB technology is usually used to bear the voice service. [0004] The main idea of ​​CSFB technology is the fourth generation of mobile communication (4 th -generation, 4G) ter...
