- the transfer station After receiving the call hold request, if the call request unit 21 in the call terminal detects that the call request is made, the transfer station returns a call request to the call terminal, so that the voice originating unit 22 of the call terminal can initiate voice data. Launch.
- the call terminal stops transmitting voice data the call can be held by sending a call hold request, and the user of the call terminal does not need to operate the button to re-establish the call connection, which is transparent to the user, which simplifies the call.
- the two parties use only one time slot, that is, the first time slot, when making a call.
- data is transmitted in one time slot and data is received in another time slot, which can reduce resource consumption.
- the repeater can determine which call party initiates the transmission of the voice data, and can prevent the users of both parties from speaking at the same time and simultaneously transmit the voice data. conflict.
- the call terminal may further include a voice storage unit 23 and a call ending unit 24 (indicated by a broken line in Fig. 13), where:
- a voice storage unit 23 configured to store user input voice data before initiating transmission of the first voice data
- the call ending unit 24 is configured to: if the call terminal does not receive the call hold request sent by the second party for N consecutive times, and does not receive the second voice data sent by the second party at a preset time , then send a call end request.
- the voice initiating unit 22 before the voice initiating unit 22 initiates the first voice data, if the user has input part of the voice data, the user may input the voice data through the voice storage unit 23, and then When the voice initiating unit 22 initiates the transmission of the first voice data, the non-speech portion of the first voice data may be removed, and the user input voice data buffered by the voice storage unit 23 and the non-voice portion removed may be transmitted. A voice data so that the voice input by the user is not discarded.
- the above call holding unit 20 is further configured to: if the voice is initiated The unit 22 does not transmit the first voice data within a preset time, and the voice receiving unit included in the call terminal does not receive the second voice data transmitted by the second party, and sends a call hold request to the second party. . And if the call hold request sent by the second party is not received N times in a row, and the second voice data transmitted by the second party is not received within a preset time, the call ending unit 24 sends a call end request. To end the call; or if the user of the call terminal hangs up, the call termination unit 24 also sends a call end request to end the call.
- the call terminal of this embodiment may further include a call setup unit (not shown in FIG. 13).
- the call setup unit may send a call setup request, when receiving the second caller.
- the voice initiating unit 22 transmits the first voice data in the first time slot.
- the embodiment of the present invention further provides a relay station, which is mainly used for transferring a call between a first party and a second party in a first time slot, and the relay station can perform a call according to the method in the third embodiment. As shown in Figure 14, it includes:
- the forwarding unit 30 is configured to forward the call hold request sent by the first party to the second party, where the call hold request is that the first party detects that the first party stops inputting Sent when voice data is sent;
- the call response unit 31 is configured to: when the forwarding unit 30 forwards the call hold request, if the first call party detects that the call request is sent, the call request is sent to the first caller, so that the first a call party initiates transmission of the first voice data; or, if it is detected that the second party sends a call request, and responds to the second call party with the call request, so that the second party initiates The transmission of the second voice data.
- the relay station in the embodiment of the present invention forwards the call between the first party and the second party
- the first party detects the stop of the data voice data
- it sends a call hold request to keep the call of both parties in the call station.
- the forwarding unit 30 forwards the call hold request to the second party. If the call response unit 31 detects that the first party sends a call request, the call is returned to the first party, so that the first party The transmission of voice data can be initiated.
- the call can be held by sending a call hold request, and the user of the caller is not required to operate the button to re-establish the call connection, which is transparent to the user, which simplifies the call.
- the relay station can determine which call party initiates the transmission of the voice data, and can prevent the users of both parties from speaking at the same time and simultaneously transmit the voice data. conflict.
- the repeater station may further include an end forwarding unit 32 (the dotted line frame in FIG. 14 indicates a structure that can be further added), specifically if the call end request sent by the first party is received Sending the call end request to the second party at least once to end the call; wherein, the call end request is that the first party does not receive the call sent by the second party for N consecutive times
- the request is kept and is transmitted when the second voice data transmitted by the second party is not received at a preset time.
- the embodiment of the present invention further provides a call system, including a first call terminal and a second call terminal, the structure of which is similar to the call system in FIG. 1, wherein the structure of the first call terminal is the same as that of FIG. 11 or 12 above.
- the structure of the illustrated call terminal is similar, except that the call request unit 12 may not be included in the first call terminal.
- the second call terminal is configured to initiate transmission of the second voice data in the second partial frame of the first time slot after receiving the call hold request sent by the first call terminal.
- the embodiment of the present invention further provides a call system, including a first call terminal, a relay station and a second call terminal, and the structure diagram thereof is similar to the call system in FIG. 6, wherein the structure of the first call terminal and the above FIG. 13 The structure of the illustrated call terminal is similar and will not be described here.
- a relay station configured to: after receiving the call hold request sent by the first call terminal, if the call request sent by the first call terminal is detected, respond to the call request to the first call terminal, where
- the structure may be similar to the structure of the repeater shown in FIG. 14 above;
- a second call terminal configured to receive first voice data transmitted by the first call terminal.
- the program may be stored in a computer readable storage medium, and the storage medium may include: Read only memory (ROM), random access memory (RAM), magnetic or optical disk, and the like.
