Right to speak preempt implementation of broadband trunking system based on Lte

摘要

A method for implementing speaking right seizing of an LTE-based broadband cluster system, an MME, a network subsystem, a broadband wireless access subsystem and the LTE-based broadband cluster system are disclosed. The method includes: the broadband wireless access subsystem sending a trunking speaking right update request to the network subsystem, receiving trunking speaking right update accept message returned by the network subsystem, and sending the trunking speaking right update accept message to the speaking right seizing terminal; the broadband wireless access subsystem, the network subsystem and the speaking right terminal interacting to complete a trunking speaking right context modification; and the broadband wireless access subsystem receiving speaking right occupation prompt message sent by the network subsystem, and sending trunking speaking right occupation prompt message to the speaking right terminal and the speaking right seizing terminal via a multicast control channel of an eMBMS and updating configuration information.
