Problems solved by technology
However, there are unavoidable shortcomings in the establishment of these two types of group calls. The method of establishing a group call according to the TA list will cause waste of resources in some cases, while the method of establishing a group call according to the cell list will be in the current cell where the trunking communication terminal is located. If it is not in the cell list, the trunking communication terminal will not be able to receive the group call service

Embodiment Construction
[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. It should be understood that the specific embodiments described here are only used to explain the present application, but not to limit the present application. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.
[0028] The term "and / or" in this article is just an association relationship describing associated objects, which means that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist simultaneously, and there exists alone B these three situations. In addition, the character " / " in this article generally indicates that the contextual objects are an "or" relationship. In additi...

The application discloses a method for triggering TAU (Tracking Area Update) by a trunking communication terminal. The method comprises the following steps: judging whether a trunking communication terminal is in a preset state and monitoring whether the trunking communication terminal carries out a cell reselection process, wherein the preset state is that the trunking communication terminal is in an idle state and is not in group calling business; when it is judged that the trunking communication terminal is in the preset state and carries out the cell reselection process, the process of theTAU is triggered so that a broadband trunking core network learns identification information of a cell where the trunking communication terminal is currently located. Through the method, it can be better realized that when the trunking communication terminal is in the preset state and carries out the cell reselection process, the TAU process is triggered so that the broadband trunking core network learns the identification information corresponding to the cell reselected by the trunking communication terminal in time. The application also provides a method for triggering TAU (Tracking Area Update) by a trunking communication terminal, a broadband trunking communication system and a related device.
Description
technical field [0001] The present application relates to the communication field, in particular to a method for triggering a TAU (Tracking Area Update) by a trunking communication terminal, a communication system and related devices. Background technique [0002] In broadband trunking communication, a group call can be established according to the specified TA (Tracking Area) list or cell list. However, there are unavoidable shortcomings in the establishment of these two types of group calls. The method of establishing a group call according to the TA list will cause waste of resources in some cases, while the method of establishing a group call according to the cell list will be in the current cell where the trunking communication terminal is located. If it is not in the cell list, the trunking communication terminal cannot receive the group call service. Therefore need a kind of method that can solve above-mentioned technical problem.
