Embodiment
Reach technological means and the effect that predetermined purpose is taked for further setting forth the present invention, below in conjunction with accompanying drawing and preferred embodiment, the method and system that group conversation state presents in real time in the described PTT session that the present invention is proposed, describe in detail as after.
First embodiment of the invention, as shown in Figure 2, the method that group conversation state presents in real time in a kind of PTT session comprises the steps:
After step 101, group call were initiated, the PTT crosspoint sent to MSC by Signaling System Number 7 with current group member talking state, and the content of carrying in the described Signaling System Number 7 comprises the talking state of the group member of group member telephone number and correspondence.
Talking state after step 104, MSC change described group member sends other group members in the group call to by the progress message in the L3 signaling.These other group members also can be all related group members of group call, and MSC is the talking state that sends after the address sends described group member variation according to the group member telephone number that obtains from the PTT crosspoint.
The following describes the reason that the present invention adopts the User-user message elements transmission group call status information of progress message:
General PTT message is to carry by note as management and group with presenting message, and we know that note is because the real-time problem can not satisfy the transmission of transmitting group conversation state information in the PTT session.
So we must have more real-time means to transmit, the relevant signaling in research CS territory, we find that progress message can satisfy our requirement from aspects such as real-time, effect time domain and portability content-lengths:
1) progress message is real-time;
2) time domain that can have an effect for progress message of whole group call process;
3) content that need carry is a group conversation state information, the length of the user-user message elements of message can be 131 bytes, skim 3 bytes in packet header of front, also have 128 operable bytes of reality, and generally in the PTT session, adopt character string as shown in the table to characterize each group member in the group call:
| Group id | Group member 1 (member id+ current state) | Group member 2 (member id+ current state) | ...... | Group member n (member id+ current state) |
Because general mobile call terminal support is no more than 32 groups, account for 5bit at most, every group membership is no more than 32, account for 5bit at most, and state also can not surpass 8 kinds, accounts for 3bit at most, and actual group conversation state information, take 5bit+ (5bit+3bit) * 32=33 byte at most, even add some protocol header fields, the length of the user-user message elements of progress message also is enough to use.
Second embodiment of the invention, as shown in Figure 3, the method that group conversation state presents in real time in a kind of PTT session comprises the steps:
After step 201, group call were initiated, the PTT crosspoint sent to MSC by Signaling System Number 7 with current group member talking state, and the content of carrying in the described Signaling System Number 7 comprises the talking state of the group member of group member telephone number and correspondence.
Talking state after step 204, MSC change described group member sends other group members in the group call to by the progress message in the L3 signaling.These other group members also can be all related group members of group call, and MSC is the talking state that sends after the address sends described group member variation according to the group member telephone number that obtains from the PTT crosspoint.
Whether the difference of the present embodiment and first embodiment is to have in group member is judged the User-user message elements of Progress message the agreement of group conversation state information to differentiate after the word User-user protocoldiscriminator, increased group member and judged whether self is in the step of group conversation state, its objective is in order in the process of mobile communication, not influence the occasion of existing application Progress message, and when wrong and abnormality occurring, the method that adopts the described group conversation state of present embodiment to present in real time, can also guarantee the talking state of other group members of grasp that group member in the current group call can be real-time and correct, because to the user in the non-current group call, even, can not produce any influence to it owing to reasons such as other application scenario or system exception have been received Progress message yet.
Third embodiment of the invention, the system that group conversation state presents in real time in a kind of PTT session, as shown in Figure 5, group of the prior art represents with the chain-dotted line four-headed arrow with the transmission that presents message, call signaling and exchange of speech are represented with the solid line four-headed arrow, the transmission of the progress message of the transmission group call status information that the present invention adopts represents that with unidirectional double dotted arrow this system comprises:
Mobile call terminal, be used for initiating or receive group call as group member, receive the progress message of the talking state that carries group member that MSC sends simultaneously, and data format by appointment parses group member from progress message talking state is presented at this locality;
The PTT crosspoint, be used for the talking state of group member being sent to MSC by Signaling System Number 7, because the PTT crosspoint is being grasped the talking state of all group members in the group call, the present invention is on the basis of PPT crosspoint existing capability, the talking state of all group members of its grasp is sent to MSC by Signaling System Number 7, inform to each group member through MSC again;
MSC, be used for the talking state of group member is sent to the group member of group call, specifically comprise: after group call was initiated, the group member talking state that MSC sends the PTT crosspoint sent all members in the group call to by the progress message in the L3 signaling;
