Group calling service rapid-continuing method

Abstract

The invention discloses a group calling service rapid-continuing method, which is applied after the cell reselection of called user equipment (UE) in group calling in time vision long term evolution broadband digital trunking mobile communication system. The method comprises that: the UE transmits a message carrying a first cell to a base station where a target cell is, wherein the first cell represents a group calling service performed in a source cell by the UE; after receiving the message carrying the first cell, the base station transmits a group calling paging message to the UE; and the UE continues the group calling service according to the group calling paging message. By the group calling service rapid-continuing method, an original group calling service can be rapidly continued after the cell reselection of the UE, so the continuity and real-time of the group calling service are improved.

Description

technical field [0001] The invention relates to the TD-LTE broadband digital trunking mobile communication system technology, in particular to a method for quickly connecting group call services. Background technique [0002] In the TD-LTE broadband digital trunking mobile communication system, after the group call called UE in the idle state (that is: the called UE of the group call service) is reselected to the target cell, it needs to quickly connect the original group call service in order to improve the efficiency of the group call service. Business continuity and real-time. [0003] In the TD-LTE broadband digital trunking mobile communication system, each cell adopts an interference-coordinated resource allocation method. For a certain group call service, the resources allocated between adjacent cells and the Group Radio Network Temporary Identity (G_RNTI: Group Radio Network Temporary Identity) Therefore, after the group call UE is reselected to the target cell, how...

Problems solved by technology

[0005] Since the paging message of the periodic group call service is sent every 5s, when the called UE of the group call reselects to the target cell, the paging message of the group call service with a period of 5s has been sent before, which makes the called UE of the group call The paging control information can only be obtained in the next paging message to continue the original group call service, so the service continuity and real-time performance of the group call UE reselected to the target cell cannot be guaranteed, resulting in data frame loss
