Problems solved by technology

However, in the ongoing 3GPP single-cell PTM project, the paging channel for group communication may not be defined
Therefore, the group information configuration method defined in the B-TrunC standard cannot be used for group communication using the MBMS architecture

Embodiment Construction

[0014] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below.

[0015] The group communication method of this embodiment is applicable to a cluster communication system adopting an MBMS architecture, and the eNB periodically sends group configuration information through the MCCH channel, and the specific steps are as follows:

[0016] Step 1: The UE obtains some basic configuration information of the group at the application level, for example, the group name, the group identifier, or TMGI.

[0017] Step 2: The eNB broadcasts the cycle, subframe information, etc. of the MCCH channel to periodically send group configuration information in the system broadcast. Here, in order to achieve the purpose of power saving of the terminal, the subframe is selected as the paging subframe in the cell.

Abstract

The present invention provides a group communication establishing and communication method in a cluster communication system. The method comprises: the cluster communication system employs an MBMS configuration, the eNB periodically sends group configuration information through an MCCH channel, and the MCCH channel employs a dynamic scheduling mode when the eNB periodically sends group configuration information; the eNB sends the scheduling information of an MCCH signaling through an M-RNTI, the MCCH signaling is group configuration information which includes group identification and a group G-RNTI, and the group G-RNTI is a group temporary identification distributed by the eNB and is configured for scrambling of the scheduling information of the group data; the UE obtains the scheduling information of the MCCH signaling through an M-RNTI, the MCCH signaling is analyzed to obtain the group configuration information, the scheduling information of the group data is obtained through the group G-RNIT, and finally, the group data is obtained.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a group communication establishment and communication method in a cluster communication system. Background technique [0002] The trunking communication system has become a vital special communication system besides the public mobile communication system. Because of its command and dispatch and emergency features (such as one-button intercom, emergency call and multi-group dispatch, etc.), it has been widely used in many important industries including the army, airport, public security, railway and electric power. application. [0003] Although the trunking communication system is in an extremely important position, compared with the public mobile communication, there are many problems in the trunking communication system in terms of scale, standard, openness, compatibility and other aspects. With the development of public network wireless communication technology, people ...
