Embodiment Construction

[0024] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0025] The main idea of ​​the present invention is: after the group call UE performs cell reselection, the UE sends the message to the base station where the target cell is located (hereinafter referred to as the target base station) to carry the group call service that the UE is in the source cell. information element, so that the base station can determine according to the information element that the UE needs to quickly connect its group call service in the source cell in the target cell, and send the group call paging message of the group call service to the UE as soon as possible, thereby facilitating The group called UE quickly connects to the group call service, maintaining the continuity and real-time performance of the group call service.

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...
