The embodiment of the present invention one
A kind of call method is provided, can be applied in phone system as shown in Figure 1, in call system as shown in Figure 1
It include: the first correspondent in system, and the second correspondent connected between the first correspondent, i.e., by straight-through between both call sides
Mode connection.Wherein, the first correspondent and the second correspondent refer to the terminal device that can carry out voice communication, such as intercom
Or terminal such as mobile phone that wireless communication may be implemented etc..
The call method flow chart of the embodiment of the present invention is as shown in Figure 2, comprising:
Step 101, it when the first correspondent detects that the first correspondent stops input voice data, sends calling and keeps asking
It asks, for example control signaling block keeps (Control Signalling BlocK, CSBK-remain, abbreviation C-R) request.
It is appreciated that the communication in the present embodiment between the first correspondent and the second correspondent can be using double time slot (tools
Body is the first time slot and the second time slot) the communication technology, for example use time division multiple acess (Time Division Multiple
Access, TDMA) communication technology, it only can be wherein in a time slot (such as first time slot) in the call method of the present embodiment
It converses, and the first correspondent and the second correspondent can transmit data or other business in another time slot.
It specifically, after call setup, can be with for one of correspondent (such as first correspondent) in the present embodiment
Microphone and loudspeaker are opened, when the first correspondent is in the state of transmitting voice data, from microphone input voice data,
And the transmitting module as included by the first correspondent is emitted, at this moment loudspeaker not output data, when the first correspondent detects
Microphone stops input voice data, illustrates that user pipes down, then first correspondent can be by transmitting module at first
Gap sends calling and keeps request, for keeping established calling between the first correspondent and the second correspondent.In order to avoid two
Conflict caused by the user of a correspondent speaks simultaneously, can execute following step 102 and 103.
Further, if the first correspondent is in when receiving voice data, microphone input data are not used, once loudspeaker
Stopping voice data output, then first correspondent is detected to whether microphone inputs voice data, if detected
Voice data can then open transmitting module.
Step 102, the first correspondent initiates the transmitting of the first voice data in first part's frame of the first time slot.
Step 103, request is kept when the second correspondent receives above-mentioned calling, is sent out in the second part frame of the first time slot
Play the transmitting of second speech data.
Above-mentioned first voice data and second speech data respectively refer to the voice of the first correspondent and the transmitting of the second correspondent
Data；Above-mentioned first part's frame and second part frame refer to the different frame on the first time slot, for example first part's frame is odd number
(Odd number) frame, second part frame are even number (even number) frame etc.；And the transmitting of the above-mentioned a certain voice data of initiation
Refer to the microphone input voice data by correspondent, and the voice number is emitted by transmitting module included by correspondent
According to.
Further, if corresponding to frame (i.e. in the transmitting that a certain correspondent (such as first correspondent) initiates voice data
First part's frame) before, the user of first correspondent, which has begun, to speak, then the first correspondent can be by the received use of microphone
Family input voice data is first cached；And made in first part's frame, when first correspondent initiates the first voice data
When transmitting, the first correspondent can partially remove non-voice (no-vad) in first voice data, concurrently shoot non-voice
The first partial voice data, and emit the user in the frame that sky gets off and input voice data.Wherein the first correspondent is removed
Non-speech portion occupied by frame length, can with the user of above-mentioned caching input voice data occupied by frame length one
It causes, for example is all 60ms.Wherein user has certain gap when speaking between each word and each word, i.e., no voice
Part, then the first correspondent removes the part (non-speech portion) in above-mentioned first voice data, can emit caching
User inputs voice data, is equivalent to and accelerates the voice of user, for example accelerates 120ms, and human ear will not generally discover this
Kind variation, therefore when being sent to the second correspondent, user experience will not produce too big variation, while it is defeated to abandon user
The voice entered.
Such as shown in Fig. 3, mobile station (Moble Station, MS) is conversed between A and mobile station B, when the use of MS A
Family pipes down, and MS A can be packaged ending message in F frame and send C-R request (shown in Fig. 3), then the MS A can be at it
Even frame (E frame) afterwards initiates the transmitting of voice data；When MS B is after receiving above-mentioned C-R request, in odd-numbered frame (O frame) hair
Play the transmitting of voice data.Equally, when MS B stop input voice data concurrency sent C-R request after, can be in even frame
Continue the transmitting of initiation voice data, and so on.
Wherein, when user pipes down, mobile station can also becalm in the Mike for detecting that the mobile station includes
The frame for only inputting voice data is packaged ending message；And A to F is a superframe in Fig. 3, indicates that the mobile station is emitting language
Sound data, and the upright reception voice data of opposite end call.
As it can be seen that under the mode that both call sides are straight-through, when the first correspondent and the second correspondent by the first time slot into
During row call, when the first correspondent is detecting that transmission calling keeps request to keep when stopping data-voice data
The calling of both call sides, and in first part's frame of the first time slot initiate voice data transmitting, and the second correspondent be
Receive the transmitting that voice data is initiated in the second part frame after calling keeps request.In this way when a certain correspondent is stopping sending out
When penetrating voice data, request can be kept to keep calling by sending to call, without the user's operation of a certain correspondent
Key re-establishes calling connection, be for a user it is transparent, can simplify user's operation in communication process in this way, and
Calling is established due to not needing to be repeated several times, so that communication process is more continuous.
In addition, two correspondents only use a time slot i.e. the first time slot when being conversed, compared with the existing technology in
Emit data in one time slot, receives data in another time slot, it is possible to reduce resource consumption.
Further, in the method for the present embodiment, after keeping request to keep calling connection by calling, both call sides are
The transmitting of voice data is initiated in the different frame of the first time slot, can be spoken simultaneously and be caused simultaneously to avoid the user of both call sides
Emit the conflict of voice data.
It should be noted that above-mentioned steps 101 to 103 illustrate, when the first correspondent and the second correspondent are being established
Call after calling, and before above-mentioned steps 101, the first correspondent can also lead to following step 104 and 105 realizations and exhale
The foundation cried；And by step 106 after above-mentioned steps 105, the calling that may be implemented in another case is kept.Flow chart
As shown in Figure 4, comprising:
Step 104, the first correspondent sends setup requests in the first time slot, for example control signaling block is established
(CSBK-setup, C-S) is requested to the second correspondent, after the second correspondent receives the setup requests, the second call
The user of side can be with off-hook, then the second correspondent will return to call answering (call answer).
Step 105, when the first correspondent receives the call answering of the second correspondent transmission, in the first slot transmission first
Voice data.
When the first correspondent and the second correspondent after the call is set up, both call sides can the first time slot carry out voice number
According to transmission, for one of correspondent when emitting voice data, another correspondent can be only in reception state, in this process
In, if correspondent when emitting voice data, only can open transmitting module without opening receiving module, if correspondent exists
When receiving voice data, receiving module is only opened without opening transmitting module；And any correspondent is only having voice
When data are input to microphone, which can open transmitting module just now to emit voice data, and otherwise transmitting module can be in
Closed state.The resource consumption of correspondent can be reduced in this way.
Step 106, if the first correspondent does not emit the first voice data within the preset time, and it is logical not receive second
The second speech data that words side emits, the first correspondent send calling and keep request to the second correspondent.
If after the first correspondent and the second correspondent establish calling, if any correspondent is all without transmitting voice number
According to, in order to keep the calling of the foundation, need correspondent send calling keep request.Further, if any correspondent (ratio
Such as the first correspondent) continuous n times (such as twice) do not receive the calling of the second correspondent transmission and keep request, and the first call
Side does not receive the second speech data of the second correspondent transmitting in the preset time, then the first correspondent sends end of calling and asks
It asks, such as control signaling block end (CSBK-Drop, C-D) request, to terminate the calling connection.
And it should be noted that above-mentioned steps 101 to 103, and there is no absolute ordinal relation between step 106, it can be with
It is performed simultaneously, can also sequentially execute, be one of concrete implementation method shown in Fig. 4.
Such as shown in Fig. 5 a, MS A can send C-S in the first time slot and request to give MS B, which can automatically reply confirmation and receive
The confirmation message (ACK) requested to the C-S, then both sides' mobile station can jingle bell；After user's off-hook of MS B, calling can be returned
MS A is given in response；When MS A receives the call answering, voice data will be emitted, i.e., emitted in A to the F frame of the first time slot
Voice data.Wherein, if system is higher to the time requirement of shaking hands of call setup, above-mentioned MS B can not need to reply
ACK, direct jingle bell.
Such as shown in Fig. 5 b, after MS A and MS B establish calling, when MS A stopping transmitting voice data, and C- is had sent
After R request, if all without voice data transmissions in two superframes (A to F is a superframe), and the language without receiving MS B
Sound data can send C-R request again then to keep calling connection.
The embodiment of the present invention two
A kind of call method is provided, mainly can be applied in phone system as shown in FIG. 6, as shown in FIG. 6 logical
It include: the first correspondent, intermediate station and the second correspondent in telephone system, the first correspondent is connected by intermediate station and the second correspondent
It connects, i.e., is connected between both call sides by transfer mode.Wherein, during intermediate station can refer to that base station or repeater etc. may be implemented
The equipment turned.
The call method of the present embodiment is in phone system as shown in FIG. 6, by any correspondent such as the first correspondent
Performed method, flow chart as shown in fig. 7, comprises:
Step 201, it when the first correspondent detects that the first correspondent stops input voice data, sends calling and keeps asking
Such as C-R is asked to request.
It is appreciated that the communication in the present embodiment between the first correspondent and the second correspondent can be using the logical of double time slots
Letter technology can only be conversed in a time slot (such as first time slot) wherein in the call method of the present embodiment, and the
One correspondent and the second correspondent can transmit data or other business in another time slot.
Specifically, in the present embodiment, after call setup, one of correspondent (such as first correspondent) is in
When emitting the state of voice data, from microphone input voice data, and the transmitting module as included by the first correspondent is carried out
Transmitting, at this moment loudspeaker not output data, and the voice data emitted is that the second correspondent is then forwarded to by intermediate station.When first
Correspondent detects that microphone stops input voice data, illustrates that user pipes down, then first correspondent can pass through transmitting
Module sends calling in the first time slot and keeps request, exhales for keeping established between the first correspondent and the second correspondent
It cries, which keeps request that can first be sent to intermediate station, and then intermediate station is then forwarded to the second correspondent.
Step 202, the first correspondent sends call request (req), in order to detect that the first correspondent is sent out when intermediate station
Call request out responds the call request to first correspondent, and specifically, intermediate station replys close-talking response to the first correspondent
(rsp)。
Step 203, the first correspondent receives response of the intermediate station to call request, initiates the hair of the first voice data
It penetrates.
Specifically, after the first correspondent is having sent calling and keeps request, then the first correspondent and the second correspondent be all
Voice data can be emitted, conflict caused by speaking simultaneously in order to avoid the user of two correspondents, when intermediate station is receiving
After calling keeps request, it is connected to the voice data of which correspondent transmitting for the first time, then is equivalent to the correspondent and has sent call and ask
Ask, can determine to allow the correspondent to initiate voice data, and another correspondent automatically into reception state to receive voice data；
If intermediate station receives the voice data of both call sides transmitting simultaneously, determine to allow the stronger correspondent of signal strength
Initiate the transmitting of voice data.
Further, if a certain correspondent (such as first correspondent) initiate voice data transmitting correspond to frame it
Before, the user of first correspondent, which has begun, to speak, then the received user of microphone can be inputted voice number by the first correspondent
According to being first cached；And when intermediate station allows first correspondent to initiate the transmitting of the first voice data, the first correspondent meeting
Non-voice (no-vad) in first voice data is partially removed, and emits the first voice number for removing non-speech portion
According to, and the user for emitting in the frame that gets off of sky above-mentioned caching inputs voice data.And wherein, the first correspondent is in the first voice
The length of frame occupied by the non-speech portion removed in data inputs the length one of frame occupied by voice data with above-mentioned user
It causes.
As it can be seen that in the case where both call sides are the mode of transfer, when the first correspondent and the second correspondent by the first time slot into
During row call, when the first correspondent is detecting that transmission calling keeps request to keep when stopping data-voice data
The calling of both call sides, after intermediate station, which receives the calling, keeps request, if detecting that a certain correspondent issues call and asks
It asks, then intermediate station responds the call request to the correspondent, and the correspondent in this way can initiate the transmitting of voice data.In this way
When a certain correspondent is when stopping emitting voice data, request can be kept to keep calling by sending to call, without
The user's operation key of a certain correspondent re-establishes calling connection, be for a user it is transparent, can simplify in this way
User's operation in communication process, and calling is established due to not needing to be repeated several times, so that communication process is more continuous.
In addition, two correspondents only use a time slot i.e. the first time slot when being conversed, compared with the existing technology in
Emit data in one time slot, receives data in another time slot, it is possible to reduce resource consumption.
It further,, can be by transfer after keeping request to keep calling connection by calling in the method for the present embodiment
Platform determines the transmitting which correspondent to initiate voice data by, can speak simultaneously and be caused simultaneously to avoid the user of both call sides
Emit the conflict of voice data.
It should be noted that above-mentioned steps 201 to 203 illustrate, when the first correspondent and the second correspondent are being established
Call after calling, and before above-mentioned steps 201, the first correspondent can also lead to following step 204 and 205 realize with
The call setup of second correspondent；And first correspondent can be realized another by step 206 after above-mentioned steps 205
In the case of calling keep.Flow chart is as shown in Figure 8, comprising:
Step 204, the first correspondent sends setup requests to the second correspondent in the first time slot, specifically,
The setup requests that one correspondent is sent first are sent to intermediate station, are then sent to the second correspondent by intermediate station.When second
After correspondent receives the setup requests, the user of the second correspondent can be with off-hook, then the second correspondent will be returned and be exhaled
Cry response.
Step 205, when the first correspondent receives the call answering of the second correspondent transmission, in the first slot transmission first
Voice data.
Step 206, if the first correspondent does not emit the first voice data within the preset time, and it is logical not receive second
The second speech data that words side emits, the first correspondent send calling and keep request to the second correspondent.
If after the first correspondent and the second correspondent establish calling, if any correspondent is all without transmitting voice number
According to, in order to keep the calling of the foundation, need correspondent send calling keep request.Further, if any correspondent (ratio
Such as the first correspondent) continuous n times do not receive the calling that second correspondent is sent and keep request, then and the first correspondent is sent
Call end request.
And it should be noted that above-mentioned steps 201 to 203, and there is no absolute ordinal relation between step 206, it can be with
It is performed simultaneously, can also sequentially execute, only one of concrete implementation method shown in fig. 8.
The embodiment of the present invention three
