Step C, TDS trunking dispatch server (303) send right of speech message response signaling FloorInformationNotify to MME Mobility Management Entity (301), and all wired dispatching desks of the described DC of eNodeB evolved base station (201) steps A (105) that indication MME Mobility Management Entity (301) notice participates in group calling discharge right of speech;
Step D, MME Mobility Management Entity (301) are according to the content of right of speech message response signaling FloorInformationNotify, send descending cluster Non-Access Stratum to described all the eNodeB evolved base station (201) of step C and transmit signaling DownlinkTrunkingNASTransport, described descending cluster Non-Access Stratum transmits signaling DownlinkTrunkingNASTransport and comprises right of speech prompting signaling FloorAlertWithInformation.
Step e, described all the eNodeB evolved base station (201) of step D receive right of speech prompting signaling FloorAlertWithInformation, the wired dispatching desk of the current DC of notifying user equipment UE (105) right of speech free time.
7. the implementation method of the broadband multimedia cluster system dispatching desk right of speech signaling based on TD-LTE according to claim 6 is characterized in that right of speech discharges among the demand signalling FloorReleaseRequest in the steps A to comprise: signaling type, signaling length, TDS control plane sign, DC number information, sets of numbers information and release type; Described release type comprises: keep, normally discharge and improper release.
8. the implementation method of the broadband multimedia cluster system dispatching desk right of speech signaling based on TD-LTE according to claim 6 is characterized in that right of speech discharges among the response signaling FloorReleaseResponse among the step B to comprise: signaling type, signaling length, DC control plane sign, DC number information, sets of numbers information and release type.
