Embodiment Construction

[0043] The solution of the embodiment of the present invention is mainly: configuring a predetermined system resource block carrying required configuration information corresponding to a cluster-specific FACH (Forward Access Channel, forward access channel) on the network side, and UE (user equipment, user equipment, User terminal) through cell search, open BCH (Broadcast Channel, broadcast channel) in the resident cell to read the system message including the scheduled system resource block and the scheduling information of the scheduled system resource block, and successfully camp on the cell through the system message ; In the group call service, the UE does not need to establish an RRC (Radio Resource Control, radio resource control protocol) connection. During the group call being called, the UE sends a calling establishment request message carrying all call-related parameters to the network side , to obtain the physical resource information configured by the network side ...

Abstract

The invention relates to a method for achieving cluster terminal residing and group calling and UE. The method comprises the steps that a resident cell is obtained by the UE through a cell search, a BCH is opened in the resident cell so that system information can be read, and the system information at least comprises a booking system resource block and dispatching information of the booking system resource block; according to the booking system resource block and the dispatching information of the booking system resource block, cell residing is conducted. According to the method for achieving cluster terminal residing and group calling and the UE, cell residing of the UE can be successfully achieved through the system information; when a group calling service is conducted, RRC connection does not need to be established by the UE; a group calling resource configuration message sent by an FACH is obtained according to the configuration information in the booking system resource block, a corresponding channel resource is established, a called voice service of group calling is conducted, delay of UE cluster group calling is shortened, and further, the effect of the user experience is improved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method for realizing cluster terminal camping and group calling under the TD-SCDMA (TimeDivision-Synchronous Code Division Multiple Access) system and UE. Background technique [0002] The trunking communication service is a half-duplex two-way service that can realize one-to-many services. Its characteristic is that when the trunking terminal initiates a group call service, its voice information can be sent to each of the predefined trunking groups at the same time. members, and the business builds fast. Among them, the trunking service functions include group call, individual call, speaking right application, speaking right release, and speaking right preemption. The biggest feature of trunking communication is that the voice communication adopts PTT (Push To Talk, Push To Talk) mode to connect, and the called party can answer without picking up the ph...
