S11. control device receives demand signalling of the calling terminal in the non-real time voice calling transmitted by control channel, institute
It states demand signalling and includes calling terminal identification, called terminal mark and voice duration, wherein, a length of caller during the voice
Terminal receive calling subscribe input non-real time voice service order after, receive calling subscribe voice messaging and by its into
Duration after row caching.In this step, it should be noted that, calling subscribe can be by pressing the PTT on calling terminal twice in succession
(Push-To-Talk) button inputs non-real time voice service order, is different from calling subscribe and passes through by a calling terminal
On PTT buttons come input real time voice traffic instruction.In addition, when calling subscribe twice in succession starts to say by pressing PTT buttons
Words, unclamp PTT buttons after finishing speaking, which is converted into voice to be sent and eats dishes without rice or wine frame and to be buffered in by calling terminal
In calling terminal.Then, which initiates random access procedure in control channel, i.e., sends a non-reality to control device
When audio call demand signalling, and be accompanied in the demand signalling this non real-time calling calling terminal identification (such as
Address), called terminal mark (such as address) and voice duration；
S12. control device detects the idle ascending resource of current auxiliary control channel, if there is the sky more than the voice duration
Not busy ascending resource then sends the confirmation signaling of non-real time voice calling, to indicate caller in control channel to the calling terminal
Terminal is switched to auxiliary control channel.In this step, it should be noted that, control device detects the idle uplink money of current auxiliary control channel
Source, if finding uplink auxiliary control channel current idle；(believe alternatively, carrying out specific periodic traffic if any terminal in auxiliary control
Road reports specific period message), but there are upward cycle idling-resource, and period free time length is more than voice duration, then
Control device just replys the confirmation signaling of non-real time voice calling, this call request success to calling terminal, and calling terminal is received
Auxiliary control channel is just jumped to after；Conversely, the rejection signaling of non-real time voice calling is then sent to calling terminal in control channel,
To refuse the request of this non-real time voice calling, so far this call request failure；
S13. control device sends uplink language when the free time in auxiliary control channel per period starts to the calling terminal
Sound, which is sent, allows signaling, to indicate that calling terminal can send cached voice messaging in auxiliary control channel.In this step, it needs
Illustrate, calling terminal is after receiving ascending voice and sending permission signaling, and hair is this time non real-time first on control device
Audio call voice head (includes the information such as calling terminal identification, called terminal mark, calling frame number), and starts upper hair voice
Frame after device to be controlled receives, replys to calling terminal and receives success message, completes the upstream of this non real-time calling
Journey；
S14. control device detects the free time of current auxiliary control channel after the voice messaging transmitted by calling terminal has been received
If there is the idle downlink resource more than the voice duration, non-reality is sent in control channel to called terminal for downlink resource
When audio call invitation signaling, to indicate that called terminal is switched to auxiliary control channel.In this step, it should be noted that, controls
Device detects the idle downlink resource of current auxiliary control channel, if finding downlink auxiliary control channel current idle；Alternatively, carrying out spy
Fixed periodic traffic, but there are downlink periodicity idling-resource, and period free time length is more than voice duration, then controls dress
The invitation signaling that non-real time voice calling is just issued to called terminal is put, is received so that called terminal is notified to jump to auxiliary control channel
Voice messaging；
S15. control device issues its voice messaging from calling terminal received in auxiliary control channel to called terminal,
So that called terminal plays the voice messaging.In this step, it should be noted that, if individual calling flow, called terminal connect
After harvesting voice messaging, need, to the successful message of control device feedback reception, if control device does not receive, to need again
Initiate downlink voice transmission flow；If group is exhaled, after called terminal has received voice, do not need to control device feedback whether
Receive successful message.So far entire non-real time voice call flow terminates.
Preferably, in step S14, if there is the idle downlink resource more than the voice duration, control device exists
Control channel continuously transmits the invitation signaling of the non-real time voice calling of preset times to called terminal, to indicate that called terminal is cut
Change to auxiliary control channel.In one embodiment, preset times are, for example, that three times, can avoid some called terminals in this way because of network original
Because the invitation signaling of non-real time voice calling can not be received, so that it is guaranteed that all called terminals can receive non-real time voice
The invitation signaling of calling.
Fig. 3 is the flow chart of non-real time voice method of calling embodiment two in trunked communication system of the present invention, in the implementation
In the non-real time voice method of calling of example, calling terminal follows the steps below：
S21. calling terminal receives calling subscribe's after the non-real time voice service order for receiving calling subscribe's input
Voice messaging is simultaneously cached, and sends the demand signalling of non-real time voice calling, institute to control device in control channel
It states demand signalling and includes calling terminal identification, called terminal mark and voice duration.In this step, it is preferable that can also be advance
The maximum duration of call of setting, moreover, calling terminal after the voice messaging of calling subscribe is received, first judges the voice messaging
Duration whether be more than the set maximum duration of call, if so, send out the prompting of voice messaging time-out to calling subscribe, and
A length of maximum duration of call during the voice can only cache the voice of the maximum duration of call；If it is not, then the voice when
The duration of a length of voice messaging；
S22. calling terminal is in the confirmation signaling of non-real time voice calling for receiving control device and sending in control channel
When, auxiliary control channel is switched to, wherein, for control device after the demand signalling for receiving non-real time voice calling, detection is current auxiliary
The idle ascending resource of channel is controlled, if there is the idle ascending resource more than the voice duration, is sent to calling terminal non-
The confirmation signaling of real-time voice call；
S23. calling terminal is receiving control device when the ascending voice that auxiliary control channel is sent sends permission signaling,
Auxiliary control channel sends cached voice messaging to control device.
Preferably, on the basis of above-described embodiment, after step s 21, calling terminal exists receiving control device
During the rejection signaling of non-real time voice calling that control channel is sent, preset time is waited for, and again in control channel to control
Device sends the demand signalling of non-real time voice calling, wherein, if control device, which judges that current auxiliary control channel is not present, is more than institute
The idle ascending resource of predicate sound duration then sends the rejection signaling of non-real time voice calling in control channel to calling terminal.
Fig. 4 is the flow chart of non-real time voice method of calling embodiment three in trunked communication system of the present invention, in the implementation
In the non-real time voice method of calling of example, called terminal follows the steps below：
S31. called terminal is in the invitation signaling of non-real time voice calling for receiving control device and sending in control channel
When, auxiliary control channel is switched to, wherein, the invitation signaling of the non-real time voice calling is that the control device is receiving master
After being the voice messaging transmitted by terminal, the idle downlink resource of current auxiliary control channel is detected, exists and is sent out more than calling terminal
It is sent during the idle downlink resource of the voice duration in the demand signalling of non-real time voice calling sent；
S32. the voice messaging from calling terminal that called terminal receiving control device is issued in auxiliary control channel, and play
The voice messaging.
Fig. 5 A, Fig. 5 B are that the time slot map that non-real time voice calls example IV, the embodiment are carried out in PDT systems of the present invention
Illustrate the flow of non-real time voice calling by taking calling terminal MS_A calling called terminals MS_B as an example, moreover, control device is
Base station BS, in addition, it should be noted that, in PDT systems, a frequency point corresponds to two channels, respectively auxiliary control channel (CH1
TSAC, corresponding time slot 1) and control channel (CH2 TSCC, corresponding time slot 2).
The upflow of real-time voice call with reference to shown in Fig. 5 A, first, calling subscribe press caller end twice in succession
PTT buttons on the MS_A of end start to talk, and unclamp PTT buttons after finishing speaking, calling terminal MS_A is by speech content before this
Voice to be sent is converted into eat dishes without rice or wine frame and to be buffered in calling terminal MS_A, and when a length of Tcall of the voice messaging.If limit
Maximum duration of call Tmax is determined, if moreover, Tcall>Tmax, then prompting this time call time-out, can only cache the language of Tmax
A length of Tmax when message breath, i.e. voice；If Tcall≤Tmax, a length of Tcall during voice.
Then, calling terminal MS_A initiates random access procedure on a control channel, i.e., sends a non-reality to base station BS
When audio call demand signalling, mark, the mark and language of called terminal MS_B of subsidiary calling terminal MS_A in the signaling
Sound duration Tcall, if base station BS judges that the ascending resource of current auxiliary control channel is idle, although alternatively, carrying out specific
(as shown in the figure, the period at regular intervals, terminal MS _ C will report specific period message to periodic traffic in auxiliary control channel
Period Message), but there are upward cycle idling-resource, and period free time length is more than voice duration, then base station
BS replys the confirmation signaling of calling terminal MS_A non-real time voices calling, this call request success, and calling terminal MS_A is received
After jump to auxiliary control channel；Conversely, base station BS replys the rejection signaling of calling terminal MS_A non-real time voices calling, this calling
Request failure after calling terminal MS_A is received, at regular intervals, can continue random access procedure, request is non real-time
Audio call.
Then, base station BS starts to detect auxiliary control channel, is issued when each free time in period starts to calling terminal MS_A non-
Real-time voice call allows signaling Grant Message.After calling terminal MS_A is received, this non-reality of hair first on base station BS
When audio call voice head LC_HEAD ER, it is then upper to send out speech frame VOICE multiple.Base station BS is after receiving, to master
Terminal MS _ A is made to reply and receives successful message UL ACK Message, completes the upflow of this non real-time calling.
The downflow of real-time voice call with reference to shown in Fig. 5 B, base station BS are being received transmitted by calling terminal MS_A
Voice messaging after, detect the idle downlink resource of current auxiliary control channel, auxiliary control channel is currently empty if base station BS judges downlink
Spare time, although (as shown in the figure, the period at regular intervals, base station BS will be auxiliary alternatively, carrying out specific periodic traffic
Control channel issues specific period message Period Message to terminal MS _ D), but there are downlink periodicity idling-resource, and
Period free time length is more than voice duration, then the invitation signaling of non-real time voice calling is sent to called terminal MS_B, notifies quilt
Terminal MS _ B is made to jump to auxiliary control channel to receive voice.Then, base station BS starts under the idling-resource of auxiliary control channel to quilt
Terminal MS _ B is made to send voice head LC_HEAD ER and speech frame VOICE.Moreover, because the voice call service is individual calling, then
After called terminal MS_B has received voice, need to receive successful message DL ACK Message to system feedback, so far entirely
Non-real time voice call flow terminates.
Fig. 6 A, Fig. 6 B are the flow charts of non-real time voice method of calling embodiment five in trunked communication system of the present invention,
In the non-real time voice method of calling of the embodiment, control device is base station BS, and calling terminal is terminal MS _ A, and called terminal is
Terminal MS _ X, and the quantity of called terminal MS_X can be for one or multiple.The flow of non-real time voice calling is as follows：
In step 1, base station BS issues random access in control channel and invites signaling (C_ALOHA) after working on power,
Any terminal for being in idle state can ask random access according to the random access information carried in the signaling.
In step 2, calling terminal MS_A and called terminal MS_X after powering, can be according to the internal channel informations that prewrite
Random search or according to the preferred registration channel that prewrites of inside, after detecting that random access invites signaling, to base station BS send with
Machine access message (REG_REQ) to ask to register, base station BS respectively to the identity of calling terminal MS_A and called terminal MS_X into
Row verification after verification is legal, replys confirmation message (REG_ACK), completes stepping on for calling terminal MS_A and called terminal MS_X
Note business.Hereafter the terminal can initiate the various businesses that PDT systems are supported, industry is called including non-real time voice
Business.
In step 3, calling terminal MS_A exhales request message after user presses PTT buttons in control channel transmission group
(GRP_CALL_REQ) to ask group-calling service.If all Traffic Channels of base station BS are in busy state, therefore base station BS at this time
Refuse information (GRP_CALL_REJ) is exhaled to calling terminal MS_A transmission groups, it please to refuse the group-calling service of calling terminal MS_A
