Problems solved by technology

[0003] The POC voice stream is real-time, the right to speak is switched frequently, and the duration of each talk burst is a random value. Therefore, choosing a fixed time to trigger billing will easily cause difficulties in the statistics of user billing information.
In addition, POC is a VoIP technology, and its voice stream is carried on the IP / UDP / RTP protocol. However, since UDP provides unreliable transmission services, in a talk burst, the voice stream sent by the speaker and received by the POC server The voice stream, and the voice stream forwarded by the POC server and the voice stream received by the listener may be inconsistent in size. At this time, the accurate billing of the voice stream of the speaker and the listener is particularly prominent
Similarly, voice flow-related control packets RTCP SR / RR are also carried on the IP / UDP protocol, which may easily lead to the loss of user statistical information carried by it. Therefore, it is necessary to take certain measures to improve the reliability of billing

Embodiment Construction

[0035] According to the content of the invention, the specific implementation manner of the invention will be described below in conjunction with the accompanying drawings.

[0036] First assume the following basic conditions:

[0037] - Both user A and user B are end users of the push-to-talk (POC) service based on the cellular network;

[0038] - User A and User B belong to the same Ad-hoc (peer-to-peer) group;

[0039] - user A and user B correspond to different push-to-talk (POC) service servers based on the cellular network;

[0040] -The media plane channel between user A and user B has been established.

[0041] figure 1 It shows a typical push-to-talk service voice flow charging for a push-to-talk (POC) service end user (user B) based on a cellular network based on a push-to-talk (POC) service terminal user (user A) The process is roughly as follows:

[0042] 1. User A starts to speak, and the corresponding POC voice stream reaches listening user B after controlling...

Abstract

The invention is in use for charging terminal user in 'one button through' service based on cellular network. The method includes steps: (1) speak user sends speech stream, POC server forwards speech stream and carries out statistics for flow rate; (2) when releasing right to speak, speak user sends SR message; after receiving the SR message, POC server creates charging information of the speak user based on SR message, and transferring the charging information to charging server; using charging information, the charging server charges the speak user; (3) listener sends RR message; after receiving the RR message, POC server creates charging information of the listener based on RR message and obtained statistics information of flow rate, and transferring the charging information to charging server; using charging information, the charging server charges the listener; the invention charges POC speech stream in real time, precisely and relative reliably.

Description

technical field [0001] The invention relates to a push-to-talk (POC) technology based on a cellular network in the communication field, in particular to a charging method and system for a voice flow of a push-to-talk (POC) service based on a cellular network. Background technique [0002] The POC (Push-to-Talk over Cellular) service is a push-to-talk service based on the cellular network. It uses half-duplex mode to realize direct point-to-point and point-to-multipoint communication. That is, when one party speaks, other members can only Answer, can not speak. There is no need to dial a number during a call, and the voice can be transmitted to all members of the group at the same time by pressing and holding a specific button. The receiving party can answer without any response, and the call and call connection process is completed in an instant. In order to realize this POC service, a new network element-POC server is introduced on the network side to complete the forward...
