Abstract

The invention provides a tracking area updating method, a broadcast message transmission method and a communication device. The method comprises: a terminal device receives a broadcast message periodically sent by a satellite device, the broadcast message alternately carrying tracking area codes (TACs) corresponding to one or more TAs in at least two tracking areas (TAs), and a coverage area of abeam of the satellite device belonging to the at least two TAs; and when the terminal equipment detects that the TA corresponding to the TAC in the broadcast message received in the current period does not belong to the first TA list for the first time, the TA is recorded in a second TA list, and the terminal equipment continue to detect the subsequent broadcast message by the terminal equipment,and determines whether to initiate a TA updating process or not according to the TAC in the subsequent broadcast message. The embodiments of the present application can reduce signaling overhead and save paging resources.

Description

technical field [0001] The present application relates to the communication field, in particular to a method for updating a tracking area, a method for transmitting a broadcast message, and a communication device. Background technique [0002] Satellite communication has the advantages of wide coverage, long communication distance, high reliability, high flexibility, high throughput, etc., and is not affected by geographical environment, climatic conditions and natural disasters. It has been widely used in aviation communications, maritime communications, military communications, etc. field. Introducing satellites into the future fifth-generation mobile network (5th-Generation, 5G) can provide communication services for areas that are difficult to cover by ground networks, such as oceans and forests, and can enhance the reliability of 5G communications, such as for trains and airplanes And users on these vehicles can provide more stable and high-quality communication servic...
