User equipment, cluster core network equipment and group call establishing method

Abstract

User equipment, cluster core network equipment and a group call establishing method are suitable for establishing one group call in a broadband cluster network. A group comprises n user equipment, and the n is an integer and the n is greater than 1. The method comprises the following steps of determining whether to receive the group call when a cluster paging signaling from a cluster base station is received; when the group call is determined to be received, acquiring group resource configuration information and starting to receive the group call; determining whether the cluster paging signaling includes indication information for representing that a group call state needs to be fed back; and when the cluster paging signaling is determined to include the indication information representing that the group call state needs to be fed back, feeding back information representing that the group call is received currently to a cluster core network side. In the above scheme, a network side can acquire the UE participating in group call communication.

Description

technical field [0001] The invention relates to the communication field, in particular to a user equipment, a cluster core network equipment and a method for establishing a group call. Background technique [0002] The Long Term Evolution (LTE) system is mainly applicable to point-to-point communication, that is, one user communicates with another user through the network, and does not support the function of one user sending voice or data to multiple users at the same time. In order to support this function, my country established the LTE Broadband Trunking Communication (B-TrunC) industry alliance, which is responsible for the standard formulation of broadband trunking and industrial development planning. LTE broadband trunking supports services such as broadband data, voice trunking, and multimedia trunking scheduling. It can support the establishment of a group, and a certain UE in the group can simultaneously send voice and data to other UEs in the group. Each UE can k...
