Sending and receiving method of clustering paging message

Abstract

The invention provides a sending and receiving method of a clustering paging message. The method includes that a base station informs the paging cycle of a UE (User Equipment)clustering paging and the initial paging time in every paging cycle through clustering paging configuration information; the sent clustering paging message carries a next paging message according to whether an unsent clustering paging message exists when every clustering paging message is sent for instructs whether UE monitors continuously or not in current paging cycle and the time for next sending of the clustering paging message; the UE receives the clustering paging message on a subframe corresponding to first paging time according to the received configuration information of the clustering paging; and the necessity of the continuous monitoring in current paging cycle and the time for the next sending of the clustering paging message in the current paging cycle are determined according to the received indication of every clustering paging message. The sending and receiving method of the clustering paging message can ensure the rapid establishment of group call and cannot cause message congestion.

Description

technical field [0001] The present invention relates to the sending technology of the paging message, in particular to a method for sending and receiving the group paging message. Background technique [0002] The broadband digital trunking communication system based on TD-LTE technology can not only support various multimedia services of the TD-LTE mobile communication system itself, but also provide basic trunking call services and trunking multimedia services, such as voice group calls, voice single calls, Video group call, video individual call, broadcast call, real-time video transmission, etc. In order to realize the rapid call establishment of the trunking group call service, the applicant filed an invention patent application with the application number 2012100062136 on January 10, 2012, and the invention title is "A Paging Method for Trunking Groups)", aiming at the trunking communication system The point-to-multipoint service characteristics, by modifying the air ...

AI Technical Summary

Problems solved by technology

With the continuous development of the trunking network, there are more and more trunking groups. When there are too many concurrent trunking group call services, it cannot be guaranteed that all trunking paging messages will be sent in a timely manner at the time specified in a trunking paging sending cycle. It will lead to message congestion, and the fast establishment of cluster group calls cannot be guaranteed

If the paging transmission density is increased by shortening the trunking paging message sending cycle, in the case of heavy load, even if the trunking paging message sending cycle is shortened, it may not be able to ensure that the trunking paging message is sent in a timely manner, and at the same time, frequent monitoring increases the terminal power consumption; if the number of paging cluster groups is increased by increasing the maximum number of paging cluster groups in the paging message list, the size of the transmission data packet will be increased, and the RLC TM mode is used for transmission. Once a packet is lost, Can cause a large number of group paging messages to be lost
