Description

The method and the corresponding group calling system of right of speech distribution and speech right modifying
Technical field
The present invention relates to a kind of communication technology, relate in particular to the method and the corresponding group calling system of a kind of right of speech distribution and speech right modifying.
Background technology
Digital Clustering is the main body of private radio communication now, it belongs to the mobile communication category together, but can collect command scheduling, phone, data, note, functions such as multi-media image are in one, and compare with the public and global mobile communication, a series of specific functions are arranged, particularly its unique feature and complexity is arranged at aspects such as scheduling and network configuration and security controls, as fast dispatch, group calling, broadcasting, clean culture, toll breakdown, intrusion, abbreviated addressing, Priority Call, hysteresis enters, environment is intercepted, control is shifted, dynamically reorganization, automatically retransmit, VPN networking etc., wherein many specific functions are that the public mobile communication system is not available, and its quick access response only needs the hundreds of millisecond, and cellular mobile communication needs the several seconds, and its cohort user of group effectively commands, contact, scheduling and half-duplex, single worker is that main function mode is topmost feature.The application demand of Digital Clustering has special-purpose very widely coverage rate, can spread all over all trades and professions such as railway, traffic, civil aviaton, public security.Corresponding with public mobile communication, Digital Clustering plays indispensable important function in country and global social life.
Fig. 1 is a kind of structure chart of group calling system, and Ptt server (Push to Talk Server) is the call processing server in the group system, and UE (User Equipment) is a user terminal.In the current trunked call, the mode that when first the access, adopts implicit right of speech to distribute to the distribution of right of speech, first right of speech is always distributed to calling terminal, but the mode of distributing has two kinds:
A kind of mode specifically comprises the steps: as shown in Figure 2
1, calling terminal has implied the right to apply for words by saying the initiation trunked call
2, Ptt server and calling terminal UE1 have set up when calling out and can send out terminal called member UE2 and the UE3 that invitation message is given group
3, when calling terminal and Ptt Server had successfully set up calling, UE2 and UE3 did not slowly add session for a certain reason
4, behind the calling terminal call setup, Ptt Server distributes to right of speech the concurrent right of speech grant message of calling terminal UE1 (Floor Grant) notice UE1 immediately, begins then the user of UE1 is chargeed
5, indication user 1 began speech after UE1 had received right of speech grant message (Floor Grant)
6, after user 1 began speech, UE1 sent to Ptt Server with its medium voice packet, wishes that PttServer can be transmitted to terminal called
7, because current neither one terminal called inserts, then Ptt Server have to abandon these voice packets
After calling terminal adds,, all give the calling terminal right of speech immediately no matter whether terminal called adds, allow calling terminal to begin speech, this mode is not owing to considering whether terminal called inserts, so speed is fast, but can cause calling terminal loss of voice first, reliability is bad.
Another kind of mode specifically comprises the steps: as shown in Figure 3
1, calling terminal has implied the right to apply for words by saying the initiation trunked call
2, Ptt server and calling terminal have been set up when calling out and can have been sent out terminal called member UE2 and the UE3 that invitation message is given group
3, when calling terminal and Ptt Server had successfully set up calling, UE2 and UE3 did not slowly add session for a certain reason
4, behind the calling terminal call setup, Ptt Server distributes right of speech for immediately calling terminal UE1, but wait for after at least one user adds and distribute right of speech and send Floor Grant message informing UE1 to UE1 again, send Floor Taken message informing UE2, indication UE2 prepares to answer, and PTT Server begins to gather charge information then
5, after UE1 received right of speech, the indication user can talk.User's 1 its voice of speech back are forwarded to the user 2 who adds session
After calling terminal adds, waits for that a terminal called adds after, Ptt Server just gives the calling terminal right of speech, allows calling terminal to begin speech, this mode reliability better but initially access speed is slow.
The speech right modifying flow process of prior art as shown in Figure 4, specifically comprises the steps:
1, UE1, UE2 and UE3 have added session, and UE3 holds right of speech.
2, UE1 seizes right of speech by the request of saying.
3, Ptt server judges that the priority of UE1 is higher than UE3, then determines to authorize UE1 with right of speech, and PttServer sends right of speech grant message (Floor Grant) and gives UE1.
4, its right of speech of Ptt Server transmission right of speech recovery message (Floor Revoke) notice UE3 is retracted.
5, Ptt Server sends Floor Taken message informing UE2 and UE3, and indication UE1 speech please prepare to answer, and PTT Server begins to gather charge information then
6, after UE1 received right of speech, the indication user can talk.PttServer issued in user's 1 its voice of speech back, is transmitted to UE2 and UE3 by Ptt Server
Above-described speech right modifying flow process since UE1 must receive right of speech after the user just can talk, so speech right modifying speed is slower in session.
