Detailed ways

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

The call interruption method in the narrowband ad hoc network provided by the embodiment of the present application can be applied to calls such as group calls, individual calls, all calls, and emergency calls. Among them, the call can occur in a single-site scenario or a multi-site scenario. The single-station scenario means that the transmitting terminal (the initiating terminal of the call) and the interrupting terminal (the terminal that needs to interrupt the call initiated by the transmitting terminal) belong to one base station. The multi-station scenario means that the transmitting terminal and the interrupting terminal belong to different base stations.

In the embodiments of the present application, taking group calls as an example, a call interruption method in a narrowband ad hoc network in a single-site scenario and a call interruption method in a narrowband ad hoc network in a multi-site scenario are respectively introduced. Among them, the call interruption method in the narrowband ad hoc network in the single-station scenario involves the transmitting terminal, the interruption terminal and the first base station (the base station to which the transmitting terminal belongs), and the call interruption method in the narrowband ad hoc network in the multi-station scenario involves The transmitting terminal, the interrupting terminal, the first base station and the second base station (base stations other than the base station to which the transmitting terminal belongs).

Among them, the call interruption method in the narrowband ad hoc network in the single-station scenario, as shown in Figure 1, may include the following steps:

S101. In the process of initiating a voice call, the transmitting terminal discards part of the inactive voice of the voice to be sent, and re-encodes the part of the inactive voice to be sent according to a preset rule to obtain a voice frame to be sent.

In this embodiment, the inactive speech can be understood as blank speech, a gap of speech, or a static state.

The specific implementation manner of this step is in the prior art, and details are not repeated here.

S102. The transmitting terminal embeds preset indication information in the target voice frame to be sent.

In this embodiment, the target voice frame to be sent refers to: among the voice frames to be sent, the time occupied by the accumulated discarded inactive voice is not less than the time occupied by the preset indication information.

In this embodiment, the preset indication information is used to indicate the next frame position of the voice frame to be sent by the transmission channel sending target, and the transmission channel switches to receiving.

In this embodiment, one frame of the transmit channel can transmit 60ms of speech. In this step, the embedded indication information may be 20ms indication information.

S103. The transmitting terminal sends the target to-be-sent voice frame embedded with preset indication information on the transmitting channel.

S104: The transmitting terminal sends the next frame position of the target voice frame to be sent embedded with the preset indication information on the transmitting channel, and the transmitting channel transfers to receiving.

In order to visually demonstrate the process of this embodiment, a schematic diagram of the group call interruption process in the single-station scenario shown in FIG. 2 is given.

In Figure 2, "Site1", "Site2", "Site3", "Site4" and "Site5" respectively represent base stations, "MS1", "MS2", "MS3", "MS4" and "MS5" respectively represent different terminal. Among them, "MS1" sends a group call request "G1" to "Site1", therefore, "MS1" represents the transmitting terminal, "Site1" represents the first base station, "Site2", "Site3", "Site4" and "Site5" are the second base station. "MS2" needs to interrupt the group call, therefore, "MS2" stands for interrupting the terminal. It can be seen from Fig. 2 that in the sequence indicated by "MS1", the transmitting terminal sends a voice frame embedded with preset indication information at the frame position of the transmitting channel A. And, at the next frame position of the frame position of the transmission channel A, the transmission channel switches to receiving.

S105. The first base station parses the control information in the voice frame when the voice frame is received by the receiving channel.

S106. The first base station determines whether the control information carries preset indication information, and if so, executes S107, and if not, executes S114.

In this step, the preset instruction information is used to instruct the first base station to send the voice frame on the transmit channel, and the transmit channel switches to receiving at the next frame position of the voice frame sent on the transmit channel.

In Fig. 2, in the sequence corresponding to "Site1", a voice frame carrying preset indication information is received at the frame position of receiving channel A. In this step, it is determined that the control information carries preset indication information, and S107 is executed.

S107 , the first base station sends the voice frame on the transmission channel, sends the next frame position of the voice frame on the transmission channel, and transfers the transmission channel to receive.

In FIG. 2 , the first base station sends the voice frame at the frame position of the transmission channel A, and transfers the transmission channel to the next frame position of the transmission channel to receive. That is, transmit and receive at the RC frame position of the transmit channel.

S108: In the case of receiving the voice frame, the interrupt terminal parses the control information in the voice frame.

S109: The interrupting terminal determines whether the control information carries preset indication information, and if yes, executes S110, and if not, executes S108.

S110. The interruption terminal determines whether an interruption request to be sent is stored, and if so, executes S111.

S111. The interrupting terminal receives the next frame position of the voice frame on the receiving channel, and the receiving channel forwards and transmits the interrupting request.

In this embodiment, if the control information of the voice frame received by the interrupting terminal carries preset indication information, it means that the interrupting terminal can receive the next frame position of the voice frame on the receiving channel, and then transmit the call through the receiving channel. interrupt request. That is, when the interruption terminal needs to send an interruption request, it needs to satisfy the condition that the control information of the received voice frame carries the preset indication information. In practice, when the interruption terminal needs to send an interruption request, if this condition is not met at that time, the interruption request needs to be stored, and when this condition is met, the interruption request is sent again.

Therefore, in this embodiment, when the control information in the received voice frame carries preset indication information, and the interrupt terminal stores the interrupt request to be sent, the operation of this step is performed.

In FIG. 2 , in the sequence corresponding to "MS2", the frame position of the receiving channel A is the voice frame in which the control information received by the interrupt terminal carries the preset indication information. Since the interrupt terminal stores the interrupt request to be sent, the interrupt terminal receives the next frame position of the voice frame on the receiving channel, and the receiving channel transmits the interrupt request. That is, the interrupt request is transmitted at the RC frame position of the receiving channel in FIG. 2 .

In this embodiment, the transmission of the interrupted terminal's receiving channel corresponds to the transmission of the first base station's transmission channel to reception. Therefore, in this step, after the interrupted terminal transmits the transmission interrupt request on the receiving channel, the first base station can switch to the transmission channel. An interrupt request was received.

In FIG. 2, the first base station receives the interrupt request at the RC frame position of the transmission channel.

S112. In the case of receiving the interruption request, the first base station sends an interruption request to the transmitting terminal at the position of the next frame on the transmission channel, or receives the next voice frame carrying the preset indication information in the receiving channel. The frame position is forwarded to transmit, and an interrupt request is sent to the transmitting terminal.

Since in S107, the transmission channel of the first base station is switched to reception, therefore, in this step, when the first base station receives the interruption request, the meaning represented is: the case that the first base station receives the interruption request in the transmission channel Down.

In FIG. 2, after receiving the interruption request at the RC frame position of the transmission channel, the first base station sends the interruption request at the next frame position of the transmission channel (the RC frame position of the transmission channel).

S113. The transmitting terminal ends the voice call when receiving the interrupt request.

In this embodiment, the transmitting terminal detects whether an interrupt request is received, and if so, ends the voice call.

S114. The first base station transfers the voice frame on the transmission channel.

When the first base station determines that the control information does not carry the preset indication information, the operation of this step is performed. In this step, since the preset indication information is not carried in the control information, the received voice frame is relayed according to the existing process.

It should be noted that, in this embodiment, the positions where the transmitting terminal, the first base station and the interrupting terminal perform transfer transmission or transfer reception are the "next frame position" where the voice frame is transmitted or the voice frame is received. Frame Position" is just an example. In practice, the position frame for trans-transmitting or trans-receiving can be set in advance according to actual needs, that is, "next frame position" can be replaced with "preset frame position".

FIG. 3 is a method for calling interruption in a narrowband ad hoc network in a multi-site scenario provided by an embodiment of the present application. This embodiment takes the multi-site scenario shown in FIG. 4 as an example for introduction. In FIG. 4 , “Site1”, "Site2", "Site3", "Site4" and "Site5" respectively represent base stations, and "MS1", "MS2", "MS3", "MS4" and "MS5" respectively represent different terminals. Among them, "MS1" sends a group call request "G1" to "Site1", therefore, "MS1" represents the transmitting terminal, "Site1" represents the first base station, and "MS2" needs to interrupt the group call, therefore, "MS2" represents the calling The disconnect terminal, "Site2", "Site3", "Site4", and "Site5" represent the second base station.

Therefore, in The interrupt request is transmitted at the next frame position of the receiving channel. That is, the last RC frame position of the receiving channel in FIG. 4 is forwarded to transmit the interrupt request.
