Problems solved by technology

[0003] In the current SC-PTM solution, for the terminal side to close the cluster user, the notification is purely relied on the application layer, and there is no explicit notification scheme at the bottom layer of LTE, so there will be low reliability of the cluster user shutdown operation, poor delay and air interface resources Waste and other issues

Embodiment Construction

[0030] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and examples.

[0031] After the base station establishes a cluster user, it will periodically send paging through the SC-MCCH channel to notify the terminal, and the content of the paging carries the cluster identification (ID) information of all cluster users in this cell; The base station side will stop sending corresponding paging, and this application proposes that the terminal can detect whether to close the cluster user according to this mechanism, so as to release the cluster resource on the terminal side.

[0032] figure 1 For the flowchart of the method for closing cluster users for this application, see figure 1 , the method includes:

[0033] Step 101: Judging whether the paging sent by the base station is detected, if the paging sent by the base st...

Abstract

The invention discloses a method for closing cluster users, and a terminal, which are applied to a Single Cell Point to Multipoint (SC-PTM) system. The method comprises the following steps: judging whether paging sent by a base station is detected or not; if the paging sent by the base station is detected, analyzing paging contents and judging whether the paging contents carry a cluster ID currently monitored by the terminal or not; if the paging contents do not carry the cluster ID currently monitored by the terminal, closing the cluster users corresponding to the cluster ID currently monitored by the terminal; and if the paging sent by the base station is not detected, closing the cluster users corresponding to the cluster ID currently monitored by the terminal. The method and the terminal adopting the technical scheme have the advantages that cluster closing can be rapidly responded, high reliability can be maintained, and radio resource wastes can be reduced.

Description

technical field [0001] The present application relates to the technical field of mobile communication, in particular to a method and a terminal for shutting down a cluster user. Background technique [0002] In order to better promote the development and standardization of trunking networks, the 3rd Generation Partnership Project (3GPP) introduced the Single Cell Point to Multipoint (SC-PTM: Single Cell Point to Multipoint) protocol, which is based on the physical downlink shared channel ( PDSCH) shared channel mode, introducing two logical channels, the Single Cell Multicast Control Channel (SC-MCCH: Single Cell Multicast Control Channel) and the Single Cell Multicast Traffic Channel (SC-MTCH: Single Cell MulticastTraffic Channel), which are used for transmission Control plane data and user plane data of cluster users. [0003] In the current SC-PTM solution, for the terminal side to close the cluster user, the notification is purely relied on the application layer, and th...
