Description of drawings
Fig. 1 carries out the flow chart of right of speech state and sound device State Control for the type of use speech frame in the cluster conversation of the embodiment of the invention.
Embodiment
Basic thought of the present invention is: according to the type of speech frame in the cluster conversation, the right of speech state of current cluster conversation is controlled, with realize to terminal speak right state in the cluster conversation free time, listen, say the correct deciphering of three kinds of states.Can also be further according to correctly separating the opening and closing that the right of speech state of reading comes control terminal audio parts (as loud speaker and Mike).
Be described in further detail below in conjunction with the enforcement of accompanying drawing technical scheme.
A kind of method of controlling the right of speech state in the cluster conversation mainly comprises following content:
According to the type of speech frame in the cluster conversation, the right of speech state of current cluster conversation is controlled.
Further, according to the type of speech frame in the cluster conversation, the right of speech state of current cluster conversation controlled comprise: by judge cluster converse in the type of speech frame whether be that the mode of full-speed voice frame is controlled.Like this,, and finally separate the right of speech state accuracy rate height read, in time, for the stability and the high reliability of cluster conversation provides sound assurance according to judgement to the type of speech frame.Reason is: the present invention adopts the type of speech frame is carried out the control that the judgment mode realization is understood the right of speech state, can not be subjected to the influence of wireless network signal quality, thereby can accurately, in time separate the right of speech state of reading, and stability and the high reliability finally conversed for cluster provide sound assurance; And to need not as prior art be by the condition prompting field in signaling frame control right of speech state, in case the wireless network signal difference causes any bit of condition prompting field wrong, will cause terminal to separate and read correct right of speech state, thereby cause losing speech frame, and finally have influence on the stability and the reliability of cluster conversation.
Further, when the type of judging speech frame is not the full-speed voice frame, control current right of speech state for idle.
Further, when the type of judging speech frame is the full-speed voice frame, illustrate in the cluster phone system that the someone talks.Here, to be on the safe side, can further optimize, be: when the type of judging speech frame is a plurality of continuous full-speed voice frame, can illustrate more accurately in the cluster phone system that the someone talks, like this, the accuracy of judgement is higher.At this moment, the right of speech state that current cluster is conversed is controlled also and is comprised: the switching of control right of speech state.Such as, the starting stage, when terminal rigidly connects into the cluster speech path network, be in idle condition; Terminal is monitored the speech frame that the system side of cluster conversation issues afterwards, when terminal receives a plurality of continuous full-speed voice frame of full-speed voice frame or above-mentioned further optimization, judge in the cluster phone system that the someone talks, switch to the state of listening with the right of speech state by the state of initial free time this moment; Otherwise, still keep idle state.
In sum, in cluster conversation under the idle state, the system side of cluster conversation is not issue the full-speed voice frame, and terminal receives is generally delete frame or 1/8 useless rate frame.In speech, the system side of cluster conversation can issue the full-speed voice frame as the people.Terminal judges whether to have the 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, guarantees the validity of conversation.When the individual speech frame of m (self-defined) is arranged continuously not for full-rate vocoding, then SOT state of termination is switched to idle state, mute speaker.Wherein, n and m are self-defining, all are the integer greater than 2, and n and m can be identical, also can be different.N and m be as threshold value, can define according to user's request, preferably, can get 2～5 integer.
Below to the present invention's elaboration of giving an example.
Embodiment: the flow process of right of speech state and sound equipment state being controlled according to the type of speech frame.As shown in Figure 1, may further comprise the steps:
Step 101: behind the terminal access set group network, be in idle state, the while is the Frame of receiving system side transmission incessantly.
Step 102: when the Frame that receives is speech frame, the speech frame that receives is monitored.
Here, under the idle state, system side is not issue the full-speed voice frame, and what general terminal was received is delete frame or 1/8 useless rate frame.When the people was arranged in the cluster network in speech, system side just can issue the full-speed voice frame.
Step 103: judge whether to receive continuous n full-speed voice frame, if then execution in step 104; Otherwise, execution in step 105.
Step 104: when receiving continuous n full-speed voice frame, judging has the people in speech, and the right of speech state is switched to the state of listening by the state of initial free time, opens loud speaker, plays the voice signal that receives.Execution in step 106 afterwards.
Step 105: when not receiving continuous n full-speed voice frame, judge the state that the right of speech state is still the initial free time, do not handle, that is: the state that need not switches and the unlatching loud speaker.Finish current control flow afterwards.
Step 106: at the state of right of speech state for listening, and opened under the situation of loud speaker, terminal continues the speech frame that monitoring receives.
Step 107: judge whether not receive continuous m full-speed voice frame, if then execution in step 108; Otherwise, execution in step 109.
Step 108: when not receiving continuous m full-speed voice frame, judge the right of speech state and should be the state of free time, then the right of speech state is switched to idle state by the state of listening before, and mute speaker.Execution in step 102 afterwards, continue the speech frame that receives is monitored, and whether the continuation basis receive continuous n full-speed voice frame control right of speech state.
Step 109: when receiving continuous m full-speed voice frame, judge still that the someone talks, then do not handle, that is: the state of listening before the right of speech state still saves as, and the unlatching that keeps loud speaker.Finish current control flow afterwards.
As seen: adopt the present invention, in system side, system is received when the cluster group member asks to talk, and is to notify other group members to enter the state of listening by instruction (being signaling frame) no longer as prior art, but directly speech information (being speech frame) is sent to other group members.Whether other group members' terminal is that full-speed voice frame or further a plurality of full-speed voice frames of optimizing are judged according to the speech frame that receives, and control enters to be listened or idle state.
A kind of system that controls the right of speech state in the cluster conversation, this system comprises: control unit, control unit are used for the type according to cluster conversation speech frame, and the right of speech state of current cluster conversation is controlled.
Here, whether the type that control unit is further used for by judging speech frame is the full-speed voice frame, controls.
Here, whether the type that control unit is further used for by judging speech frame is continuous a plurality of full-speed voice frame, controls.
Here, control unit is further used for the speech frame that terminal monitoring receives, and when the type of judging speech frame during for continuous a plurality of full-speed voice frame, terminal knows that current right of speech state is for idle; When the type of judging speech frame was continuous a plurality of full-speed voice frame, terminal is known in the cluster phone system had the people to talk, and controlled current right of speech state and was switched to by the free time and listen, and open loud speaker.
