Accompanying drawing explanation
Fig. 1 is the flow chart using the type of speech frame to carry out right of speech state and the control of sound device state in the cluster conversation of the embodiment of the present invention.
Embodiment
Basic thought of the present invention is: according to the type of speech frame in cluster conversation, controls the right of speech state of current cluster call, to realize free time to terminal speak right state in cluster conversation, to listen, say the correct deciphering of three kinds of states.The opening and closing that the right of speech state read carrys out control terminal audio parts (as loud speaker and Mike) can also be separated further according to correct.
Be described in further detail below in conjunction with the enforcement of accompanying drawing to technical scheme.
In cluster conversation, control a method for right of speech state, mainly comprise following content:
According to the type of speech frame in cluster conversation, the right of speech state of current cluster call is controlled.
Further, according to the type of speech frame in cluster conversation, the right of speech state of current cluster call is carried out control and comprised: by judging that whether the type of speech frame in cluster conversation is that the mode of full-speed voice frame controls.Like this, according to the judgement of the type to speech frame, and the right of speech state accuracy rate that last solution reads is high, timely, for the stability of cluster conversation and high reliability provide sound assurance.Reason is: the present invention is the control adopting the mode judged the type of speech frame to realize the deciphering of dialogue right state, the impact of wireless network signal quality can not be subject to, thus can separate reading right of speech state accurately, in time, and the final stability for cluster conversation and high reliability provide sound assurance; And without the need to being control right of speech state by the condition prompting field in signaling frame as prior art, once wireless network signal difference causes any one bit of condition prompting field wrong, terminal will be caused to separate and to read correct right of speech state, thus cause losing speech frame, and finally have influence on stability and the reliability of cluster conversation.
Further, when judging the type of speech frame not for full-speed voice frame, control current right of speech state for idle.
Further, when the type judging speech frame is full-speed voice frame, illustrate that in cluster communication system, someone talks.Here, to be on the safe side, can optimize further, be: when judging that the type of speech frame is multiple continuous print full-speed voice frame, can illustrate that in cluster communication system, someone talks more accurately, like this, the accuracy of judgement is higher.Now, control also to comprise to the right of speech state of current cluster call: the switching controlling right of speech state.Such as, the starting stage, when terminal has just accessed cluster speech path network, idle condition has been in; The speech frame that the system side of terminal to cluster conversation issues afterwards is monitored, when terminal receives multiple continuous print full-speed voice frame of full-speed voice frame or above-mentioned further optimization, judge that in cluster communication system, someone talks, now right of speech state is switched to the state of listening by initial idle state; Otherwise, still keep idle state.
In sum, under state idle in cluster conversation, the system side of cluster conversation does not issue full-speed voice frame, and what terminal received is generally delete frame or 1/8 useless rate frame.When having people when talking, the system side of cluster conversation can issue full-speed voice frame.Terminal judges whether there is people in speech by receiving the individual full-speed voice frame of continuous n (self-defined), and then switches right of speech state and sound equipment state, ensures the validity of call.In time having m (self-defined) individual speech frame not for full-rate vocoding continuously, then SOT state of termination is switched to idle state, mute speaker.Wherein, n and m is self-defining, the integer all for being greater than 2, n with m can be identical, also can be different.N and m, as threshold value, can carry out defining, preferably, can getting the integer of 2 ~ 5 according to user's request.

Here, under idle state, system side does not issue full-speed voice frame, and what general terminal received is delete frame or 1/8 useless rate frame.When having people in cluster network when talking, system side just can issue full-speed voice frame.
Step 103: judge whether to receive continuous n full-speed voice frame, if so, then performs step 104; Otherwise, perform step 105.
Step 104: when receiving continuous n full-speed voice frame, judges there is people in speech, right of speech state is switched to the state of listening by initial idle state, opens loud speaker, play the voice signal received.Perform step 106 afterwards.
Step 105: when not receiving continuous n full-speed voice frame, judges that right of speech state is still initial idle state, does not process, that is: switch without the need to state and open loud speaker.Terminate current control flow afterwards.
Step 106: be the state of listening in right of speech state, and when having opened loud speaker, terminal continues the speech frame that monitoring receives.
Step 107: judge whether not receive continuous m full-speed voice frame, if so, then performs step 108; Otherwise, perform step 109.
Step 108: when not receiving continuous m full-speed voice frame, judges that right of speech state for idle state, then should be switched to idle state by the state of listening before by right of speech state, and mute speaker.Perform step 102 afterwards, the speech frame continued receiving is monitored, and continues according to whether receiving continuous n full-speed voice frame control right of speech state.
Step 109: when receiving continuous m full-speed voice frame, judges that still someone talks, then do not process, that is: the right of speech state state of listening before still saving as, and keeps the unlatching of loud speaker.Terminate current control flow afterwards.
Visible: to adopt the present invention, in system side, system receive cluster group member ask speech time, be notify that other group members enter the state of listening by instruction (i.e. signaling frame) no longer as prior art, but directly speech information (i.e. speech frame) sent to other group members.Whether the terminal of other group members is that full-speed voice frame or multiple full-speed voice frames of optimizing further judge according to the speech frame received, and controls to enter to listen or the state of free time.
In cluster conversation, control a system for right of speech state, this system comprises: control unit, and control unit is used for the type according to speech frame in cluster conversation, controls the right of speech state of current cluster call.
Here, whether the type that control unit is further used for by judging speech frame is full-speed voice frame, controls.
