Embodiment
Generally there is three state at least in colony terminal: say state, listen state, idle condition.This state exchange of three kinds is by system decision, promptly by the state of system's control terminal.System can send various control signalings (as mentioned) to terminal for the state exchange of control terminal, and terminal is done corresponding state exchange (as Fig. 2) according to the control signaling of system:
The right of speech Idle state
Call out or receive that idle prompting message AWI (perhaps other situations are asked for an interview other state analysiss) terminal enters idle condition when terminal enters first, terminal is not made special operational when idle condition, wait for the operation of terminal or system, to enter corresponding state.
1. Idle state transfers the state of saying to
Terminal is carried out the right to apply for words, and the flow process that changes the state of saying over to by the right of speech Idle state comprises the steps: as shown in Figure 3
Step 301: terminal sends says solicitation message PTT Request;
Step 302: the terminal setting is also opened the TPTT timer, waiting system arbitration result (PTT Grant or PTT Queue result message);
Step 303: whether terminal judges receives message in timing cycle, then closes the TPTT timer as if receiving, overtime as TPTT, and then terminal is sent request failure prompting, and flow process finishes;
Step 304: if terminal is received queuing message PTT Queue result, the failure of expression application right of speech, just having other-end to take right of speech this moment, then shows corresponding prompt information, and stop this flow process that terminal is returned idle condition;
Step 305: say mandate message PTT Grant if terminal is received, in the terminal contrast PTT Grant message with IMSI information whether with the IMSI coupling of terminal self, as mate then terminal and send to system and say and authorize response message PTT Grant Acknowledge, and execution in step 306, otherwise stopping this operation, terminal returns Idle state;
Step 306: terminal switches to the reverse dedicated voice channel from reverse sharing signaling channel, does and says the interface conversion operations, comprises the interface, and sound channel etc. enter " saying " state.
2. Idle state transfers listen state to
The idle calling of terminal is answered, and the flow process that is transferred to listen state by Idle state comprises the steps:
Steps A 1: the terminal system of receiving sends takies prompting message PTT AWI (Alert WithInformantion);
Step B1: terminal is carried out and is listened channel and listen the interface conversion, comprises the interface, and sound channel etc. enter " listening " state.
Say state
Receive when terminal and to say and authorize message GRANT that terminal enters the state of saying, needs to carry out following operation:
Terminal sends reverse speech frame, says that user's the information of saying sends to system side, and is transmitted to other-end by system side.
3. say that state transfers Idle state to
The implementation that the state of saying transfers Idle state to has terminal initiatively to discharge right of speech and system forces to discharge two kinds of rights of speech, below introduces respectively:
3.1 terminal discharges the PTT button
If terminal initiatively right of speech discharges (promptly discharging the operation of saying the PTT button), transfer Idle state to by the state of saying, as shown in Figure 4, this process comprises following operation:
Step 401: terminal discharges the PTT button, carries out initiatively discharging the right of speech operation, comprises the interface, sound channel etc.;
Step 402: terminal is prepared to enter the right of speech idle condition, does not promptly wait system to respond;
Here also not real Idle state, just prepare to enter, treat to be only Idle state after system validation withdraws from the reverse dedicated voice channel.
Step 403: terminal is provided with 1 delay and says that channel indicator is true, and keeps oppositely saying channel (i.e. " reverse dedicated voice channel ");
Be provided with and postpone to say that channel indicator is to guarantee that after time-delay terminal can releasing reverse dedicated voice channel.
Step 404: terminal is sent out and is said that finishing PTTRelease message gives system;
Step 405: the terminal setting is also opened the Tpttrelease timer, and waiting system is confirmed (PTT ReleaseAcknowledge message);
Step 406: terminal is if the end response message PTT ReleaseAcknowledge that says that receives in timing cycle then closes the Tpttrelease timer, change step 407, if Tpttrelease is overtime, terminal re-sends is said end PTTRelease, if retransmit the maximum that number of times reaches setting, then directly withdraw from the reverse dedicated voice channel, terminal is provided with the vacation that is masked as that postpones to say channel, and flow process finishes;
Step 407: terminal receives that saying that system sends finish response message PTT ReleaseAcknowledge, and success (being that system allows terminal to finish to say state), the expression terminal discharges the right of speech success, and promptly terminal withdraws from the reverse dedicated voice channel, and the vacation that is masked as that postpones to say channel is set.
3.2 terminal receives that forward direction says end
Terminal receives that forward direction says end, is a kind of mode of being forced to discharge right of speech by system, carries out following operation when then terminal transfers Idle state to by the state of saying:
Steps A 2: terminal is talked, and is in the state of saying, when just taking reverse voice channel, receives that forward direction says end PTT Release;
Step B2: terminal discharges the right of speech operation, comprises the interface, sound channel etc.;
The interface is from saying the interface to idle interface, and every terminal all has the expression mode of oneself, as the demonstration idle literal of making peace, or different auditory tone cueses, or the indication of different icons.
The sound channel conversion is exactly from saying sound channel, changes to and listens sound channel (free time also is to listen sound channel).
Step C2: terminal sends says end response message PTT Release ACK, enters the right of speech Idle state.
3.3 receiving not match, terminal says mandate message
Terminal is received not match and is said that authorizing message is to be forced to discharge the another kind of mode of right of speech by system, carries out following operation when then terminal transfers Idle state to by the state of saying:
Steps A 3: terminal is talked, and is in the state of saying, when just taking reverse voice channel, receives that forward direction is said to authorize message PTT_GRANT;
Step B2: in the terminal contrast PTT Grant message with IMSI information whether with the IMSI coupling of terminal self, as the terminal that do not match is then carried out subsequent treatment, as mate then terminal and send to system and say and authorize response message PTT Grant Acknowledge, and return the state of saying;
Step B3: terminal discharges the right of speech operation, comprises the interface, sound channel etc.
4. say that state transfers listen state to
Terminal needs to transfer Idle state according to above flow process to from saying state earlier if will transfer listen state to from saying state, transfers listen state to by Idle state again.
If terminal is received at the state of saying take or idle prompting message, then do not handle.
Listen state
Take AWI if terminal was received when being in Idle state, terminal enters listen state, and terminal receives the forward direction speech frame, and this information is sent to the user.
5. listen state transfers the state of saying to
Terminal transfers " saying state " to by " listen state ", and is identical by the operating process that " Idle state " transfers " saying state " to terminal, sees Fig. 3.
6. listen state transfers Idle state to
The terminal listen state discharges, and transfers Idle state to by listen state, then carries out following operation:
Steps A 4: terminal is received the free time prompting AWI message that system sends;
Step B4: terminal is carried out idle conversion operations, comprises the interface, and sound channel etc. enter the right of speech Idle state.
If terminal when listen state, says that the user changes, then carry out following operation:
Steps A 5: terminal receives and takies AWI message, but this AWI message is different from last AWI, and as carrying the Subscriber Number difference among the AWI, or call property is not equal;
Step B5: terminal is carried out the interface conversion operations, and terminal does not change current state.
If at Idle state, listen state or when saying state, can carrying out, terminal withdraws from group calling or terminating group operation, to withdraw from group calling or terminating group.
The implementation method of digital packet terminal state exchange of the present invention has been described terminal at Idle state, listen state with say the implementation method that transforms mutually between the state, especially says the conversion method of state to listen state.
