Problems solved by technology

However, when one or some terminals in the group move, if all the terminals move out of the cell or the current TA (still within the range of the TA List), if the terminal is in an idle state, the base station cannot maintain the terminal context because the base station does not maintain the terminal context. Determine whether the group still has trunking services under the cell
On the contrary, if the terminal is in the connected state, although the base station can know the location change of the terminal, but because the relationship between the group and the terminal is not maintained on the base station side, the base station side cannot judge whether the cell (or under the TA) still exists. group business
[0004] In addition, the B-trunc broadband trunking standard does not have a corresponding design for the above-mentioned group call resource configuration changes caused by terminal movement, which recycles the occupied air interface resources, resulting in cells without trunking terminals still having to allocate air interface channel resources. It is still necessary to periodically send paging and group call configuration, which causes a great waste of precious interface air resources

Embodiment Construction

[0053] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0054] One of the core concepts of the embodiments of the present invention is to preset the association relationship table between the terminal and the cluster on the base station side, increase the management of the relationship between the terminal and the cluster to which it belongs, and for the terminal in the idle state, the core network notifies the base station that the position of the terminal changes , move out of the cell or TA area. For the terminal in the connected state, after the base station obtains the change of the terminal, it judges the change of the group resource release according to the change of the terminal. If it is judged that the terminal has moved out of the cell or TA, the base station directly initia...

Abstract

The embodiment of the invention provides a method and a system for releasing cluster resources. The method comprises the steps of presetting an association relation table on a base station side, wherein the association relation table comprises the information of a plurality of clusters, the information of all terminals in each cluster and the information a cell to which each cluster belongs; whenthe condition that one or more terminals move out of the cell to which the corresponding cluster belongs is detected, updating the association relation table; if in the updated association relation table, all the terminals in the cluster move out of the cell to which the cluster belongs, using the cluster as the cluster to be released; and releasing air interface resources occupied by the clusterto be released. According to the method and the system provided by the embodiment of the invention, the cluster resources can be controlled and managed in real time on the base station side, so that the air interface resources are more efficiently used, and the waste of the resources is avoided.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for releasing cluster resources and a system for releasing cluster resources. Background technique [0002] The group call service of the broadband trunking is a typical important service of the trunking. For trunking terminals belonging to the same group, members of the group share the same downlink channel, and signaling or data services of the group call service can be transmitted through the shared downlink channel. [0003] When a group call is established, the base station needs to establish a group call downlink shared channel for each cell of each TA under the TA (Tracking Area, tracking area) List (list) corresponding to the group call, and configure air interface resources. However, when one or some terminals in the group move, if all the terminals move out of the cell or the current TA (still within the range of the TA List), if the terminal is in an i...
