In order clearer understanding to be arranged to the present invention, below be example as the public access mobile radio in the invention with CDMA2000 EV-D0 network, be described further.As shown in Figure 2, whole system comprises terminal, wireless network, cluster subsystem, packet-switched core network.Wherein, terminal is for supporting the terminal of clustering functionality; Wireless network comprises BTS (base station transceiver), BSC/PCF (base station controller/packet data control device, both place one); Packet-switched core network comprises AAA (authentication, mandate and accounting server), PDSN (packet data serving node); The cluster subsystem comprises dispatch server PDS, deployment position device PHR, dispatch application server DAS and dispatch application client DAC.Do not comprise the wireless network of PDC and the CDMA2000 EV-D0 network that packet-switched core network is standard, just no longer specify here; And PDC places BSC (base station controller) part of CDMA2000EV-D0 wireless network, lumps together with BSC/PCF to be BSC/PCF/PDC; PDC is that A8d/A9d links to each other with the interface of BSC, belongs to internal interface, is used to transmit trunking communication relevant signaling and data.Between each network element, all connect between each network element in the group system in the packet-switched core network by IP (Internet protocol) network; Wherein PDS is connected with BSC/PDC by IP network, interface is A10d/A11d, be used to transmit trunking communication relevant signaling and data, interface meets 3GPP2 Access Network interface interoperability standard (3GPP2AccessNetwork Interfaces Interoperability Specification, standard No. A.S0001-A); Bottom adopts IP/UDP (user datagram) agreement between PDS and the local PHR server, high-rise remote authentication dial-in user service agreement (the Remote AuthenticationDial In User Service that adopts, RADIUS) agreement, authentication, mandate, charging and the PTT position of transmitting the PTT business upgraded, the management and group relevant information.DAS links to each other with PDS, and the interface between it is used for dispatching management operation signaling and the transfer of data relevant with PDS; DAS adopts the HTTP interface to link to each other with PHR, and the interface between it is used for the transmission of dispatching desk operation and PHR relevant portion signaling and data.
On trunked communication system of the present invention, the flow chart that the realization cluster service group calling is set up comprises following steps as shown in Figure 3:
The initiation terminal of 301 cluster service group callings is initiated cluster multi call by wireless network;
302 wireless networks send to scheduling controller with the group calling request, begin aerial mouthful link setup simultaneously;
303 scheduling controllers send to dispatch server with this call request again;
After 304 dispatch servers are received the group calling request, send user's information request relevant with group to the deployment position device;
The information request of 305 deployment position device response scheduling servers, and information sent to dispatch server;
306 dispatch servers are adjudicated by the information that the deployment position device provides, and as initiating the group calling request of terminal by then responding cluster service group calling, and the terminal of initiating to cluster service group calling by scheduling controller and wireless network sends response request message; Otherwise the terminal of initiating to cluster service group calling by scheduling controller and wireless network sends the refusal solicited message; Cluster service group calling is initiated terminal after receiving response message, just can begin to have sent data.
307 dispatch servers send group paging information to each scheduling controller at group place;
308 dispatch servers send group paging information to corresponding wireless network; Finish notice by wireless network to group's terminal.
Said method is a specific embodiment of the present invention, mainly is the understanding that is used for strengthening to trunked communication system of the present invention, and not exclusive implementation method.Be understandable that, for those of ordinary skills, can be equal to replacement or change according to technical scheme of the present invention and inventive concept thereof, and all these changes or replacement all should belong to the protection range of the appended claim of the present invention.
