Abstract

The invention discloses a TD-SCDMA cluster system group call setup method and system. The method comprises: a cluster terminal forwarding a group call setup request message to a PDS via an RNC, and the RNC receiving a group call connecting request message sent by the PDS and sending a group call setup response message to the cluster terminal; sending a group call service request to the PDS, notifying a NODE B of setting up a dedicated channel for this group call, and after a line link setup response of the NODE B and a service designation request of the PDS are received, respectively setting up service bearers for an IUB port and an IUDs port; and the cluster terminal carrying out a dedicated channel synchronization process with the NODE B, the RNC receiving a wireless link recovery indication sent by the NODE B after the NODE B captures an uplink synchronous signal on the cluster terminal, receiving a call setup finishing message sent by the cluster terminal, notifying the PDS that call setup is finished, receiving a grant message sent by the PDS, notifying the cluster terminal of speaking, and receiving a grant response message sent by the cluster terminal for forwarding to the PDS.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method and system for establishing a group call in a TD-SCDMA trunking system. Background technique [0002] In the prior art, the trunking communication service is a half-duplex two-way service, and it is a one-to-many service. It is characterized in that when a trunking terminal initiates a group call service, its voice information can be sent to a predefined Every member in the cluster group, and the service establishment speed is fast. Based on these characteristics, the trunking communication system is widely used in government agencies, public security fire protection, energy transportation, airport terminals, industrial and mining enterprises, military and exhibitions and other industries and occasions. [0003] The current trunking communication system is developed based on the second generation mobile communication technology, that is, the Global System of Mobile c...
