Description of drawings
Fig. 1 be of the present invention one based on the PTT service terminal user of cellular network to a typical PTT business voice flow charging flow figure based on the PTT service terminal user of cellular network;
Fig. 2 is the module diagram based on the PTT business voice flow charge system of cellular network of one embodiment of the invention.
Embodiment
According to summary of the invention, tell about the embodiment of invention below in conjunction with Figure of description.
At first suppose following primary condition:
-user A and user B are based on PTT (POC) the service terminal user of cellular network;
-user A and user B belong to same Ad-hoc (point-to-point) group;
The PTT based on cellular network (POC) service server that-user A is corresponding different with user B;
Medium face passage between-user A and the user B is set up.
It is roughly as follows to a PTT based on cellular network (POC) service terminal user's (user B) typical PTT business voice flow charging flow that Fig. 1 shows a PTT based on cellular network (POC) service terminal user (user A):
1, user A begins speech, and corresponding POC voice flow is listened to user B through the distribution of control POC server and the transparent transmission arrival of participation POC server.Control POC server this moment and participate in POC server and all can carry out traffic statistics to the voice flow of inflows/outflows, wherein, it is corresponding with the user A that makes a speech to control POC server, and participating user is with to listen to user B corresponding;
2, user A release button discharges right to speak, and sends RTCP SR (RTCP Real-time Transport Control Protocol Sender Report) message;
3, after the control POC server is received RTCP SR message from user A, to the participation POC server of user B correspondence send described control POC server according to himself to the newly-generated RTCP SR message of the traffic statistics of the forwarding voice flow of user B.Simultaneously, flow and duration information according to the entrained user A of the RTCP SR message of receiving generate charge information, send charging request message to accounting server afterwards, then receive the charge response message at user A from accounting server, accounting server charges to user A;
4, participate in the POC server transparent transmission and give user B from the RTCP SR that controls POC server;
5, after user B receives RTCP SR message, utilize the statistical information of himself to send newly-generated RTCP RR (RTCP Real-time Transport Control Protocol Receiver Report) message to participating in POC server;
6, participate in POC server and receive RTCP RR message from user B after, transmit this message to the control POC server.Simultaneously, according to the packet loss of the entrained user B of this message and the packet loss information of number of accumulation, add and participate in the transmitted traffic that POC server adds up and generate charge information together, send charging request message to accounting server afterwards, then receive the charge response message at user B from accounting server, accounting server charges to user B;
