Detailed Description
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, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, 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 application can be applied to calls such as group call, individual call, full call, emergency call and the like. The call can occur in a single-station scenario or a multi-station scenario. Wherein, the scene of the single station refers to: the transmitting terminal (originating terminal of the call) and the interrupting terminal (terminal that needs to interrupt the call originated by the transmitting terminal) belong to one base station. The multi-station scenario refers to: the transmitting terminal and the interrupting terminal belong to different base stations.
In the embodiment of the present application, a group call is taken as an example, and a call interruption method in a narrowband ad hoc network in a single-station scenario and a call interruption method in a narrowband ad hoc network in a multi-station scenario are respectively introduced. The call interruption method in the narrowband ad hoc network under the single-station scene relates to a transmitting terminal, an interruption terminal and a first base station (a base station to which the transmitting terminal belongs), and the call interruption method in the narrowband ad hoc network under the multi-station scene relates to the transmitting terminal, the interruption terminal, the first base station and a second base station (a base station except the base station to which the transmitting terminal belongs).
As shown in fig. 1, the method for interrupting a call in a narrowband ad hoc network in a single-station scenario may include the following steps:
s101, in the process of initiating a voice call, the transmitting terminal discards part of inactive voice of the voice to be transmitted, and re-encodes the voice to be transmitted with the discarded part of inactive voice according to a preset rule to obtain a voice frame to be transmitted.
In this embodiment, inactive speech may be understood as blank speech, a spoken gap, or a static state.
The specific implementation manner of this step is the prior art, and is not described herein again.
S102, embedding preset indication information in a target voice frame to be sent by a transmitting terminal.
In this embodiment, the target speech frame to be sent refers to: and in the voice frames to be sent, accumulating the voice frames to be sent, wherein the time length occupied by the discarded inactive voice is not less than the time length occupied by the preset indication information.
In this embodiment, the preset indication information is used to indicate the next frame position of the target voice frame to be sent by the sending channel, and the sending channel switches to receive.
In this embodiment, one frame of the transmit channel may transmit 60ms of speech. In this step, the embedded indication information may be 20ms indication information.
S103, the transmitting terminal transmits the target voice frame to be transmitted embedded with the preset indication information in the transmitting channel.
S104, the transmitting terminal transmits the next frame position of the target voice frame to be transmitted embedded with the preset indication information in the transmitting channel, and the transmitting channel receives the voice frame.
In order to visually show the process of the embodiment, a schematic diagram of a group call interruption process in a single-station scenario shown in fig. 2 is given.
In fig. 2, "Site 1", "Site 2", "Site 3", "Site 4", and "Site 5" denote base stations, respectively, and "MS 1", "MS 2", "MS 3", "MS 4", and "MS 5" denote different terminals, respectively. Here, "MS 1" sends a group call request "G1" to "Site 1", so "MS 1" represents a transmitting terminal, "Site 1" represents a first base station, and "Site 2", "Site 3", "Site 4" and "Site 5" are second base stations. "MS 2" needs to interrupt the group call, and therefore "MS 2" represents an interrupt terminal. As can be seen from fig. 2, in the sequence indicated by "MS 1", the transmitting terminal sends a voice frame embedded with preset indication information at the position of the transmitting channel a frame. And, at the next frame position of the transmitting channel A, the transmitting channel switches to receiving.
S105, the first base station analyzes the control information in the voice frame under the condition that the voice frame is received by the receiving channel.
S106, the first base station judges whether the control information carries preset indication information, if so, S107 is executed, and if not, S114 is executed.
In this step, the preset indication information is used to indicate the first base station to send the voice frame in the transmitting channel, and the transmitting channel switches to receive at the next frame position where the transmitting channel sends the voice frame.
In fig. 2, in the sequence corresponding to "Site 1", a voice frame carrying the preset indication information is received at the position of the a frame of the receiving channel, in this step, it is determined that the control information carries the preset indication information, and S107 is executed.
S107, the first base station sends the voice frame in the transmitting channel, and the transmitting channel receives the voice frame at the next frame position of the transmitting channel.
In fig. 2, the first base station transmits the voice frame at the frame position of the transmission channel a, and switches the transmission channel to receive at the next frame position of the transmission channel. Namely transmitting to receiving at the position of RC frame of the transmitting channel.
And S108, the interrupt terminal analyzes the control information in the voice frame under the condition of receiving the voice frame.
And S109, the interrupt terminal judges whether the control information carries preset indication information, if so, S110 is executed, and if not, S108 is executed.
And S110, judging whether an interrupt request to be sent is stored or not by the interrupt terminal, and if so, executing S111.
S111, the interrupt terminal receives the next frame position of the voice frame in the receiving channel, and the receiving channel transmits the interrupt request.
In this embodiment, if the control information of the voice frame received by the interrupt terminal carries the preset indication information, it indicates that the interrupt terminal can receive the next frame position of the voice frame in the receiving channel, and the interrupt request is forwarded through the receiving channel. That is, the interrupting terminal needs to satisfy the condition that the control information of the received voice frame carries the preset indication information under the condition that the interrupting terminal needs to send the interrupting request. In practice, when an interrupt terminal needs to send an interrupt request, if the condition is not met, the interrupt request needs to be stored, and when the condition is met, the interrupt request is sent again.
Therefore, in this embodiment, the operation of this step is executed when the control information in the received voice frame carries the preset indication information and the interrupt terminal stores the interrupt request to be sent.
In fig. 2, in the sequence corresponding to "MS 2", the position of the a frame in the receiving channel is a speech frame that interrupts the control information received by the terminal and carries the preset indication information. The interrupt terminal stores the interrupt request to be sent, so that the interrupt terminal receives the next frame position of the voice frame in the receiving channel, and the receiving channel transmits the interrupt request. I.e. the receive path RC frame position forwards the request for interruption in fig. 2.
In this embodiment, the interruption terminal switches the receiving channel to transmitting to receiving corresponding to the first base station transmitting channel, so in this step, after the interruption terminal forwards the transmission interruption request on the receiving channel, the first base station may switch to receive the interruption request on the transmitting channel.
In fig. 2, the first base station receives the request for interruption at the location of the RC frame on the transmit path.
And S112, the first base station sends the interrupt request to the transmitting terminal at the next frame position of the transmitting channel under the condition that the interrupt request is received, or the first base station transmits the interrupt request to the transmitting terminal at the next frame position after receiving the next voice frame carrying the preset indication information at the receiving channel.
Since the first base station transmits channel switching reception in S107, what the first base station means in this step when it receives the interrupt request is: the first base station receives the request for interruption on the transmit path.
In fig. 2, after receiving the request for interruption at the RC frame position of the transmission channel, the first base station sends the request for interruption at the next frame position (RC frame position of the transmission channel) of the transmission channel.
And S113, the transmitting terminal ends the voice call under the condition of receiving the interruption request.
In this embodiment, the transmitting terminal detects whether to forward the received interrupt request, and if so, ends the voice call.
S114, the first base station transfers the voice frame in a transmitting channel.
And executing the operation of the step when the first base station judges that the control information does not carry the preset indication information. In this step, since the control information does not carry the preset indication information, the received voice frame is transferred according to the existing flow.
It should be noted that, in this embodiment, the positions where the transmitting terminal, the first base station and the terminal are interrupted to perform retransmission or retransmission are "next frame positions" of transmitting voice frames or receiving voice frames, and "next frame position" is only an example. In practice, the position frame to be transmitted or received can be set in advance according to actual requirements, i.e. the "next frame position" can be replaced by the "preset frame position".

Here, "MS 1" sends a group call request "G1" to "Site 1", so "MS 1" represents a transmitting terminal, "Site 1" represents a first base station, and "MS 2" needs to break the group call, so "MS 2" represents a breaking terminal, and "Site 2", "Site 3", "Site 4", and "Site 5" represent a second base station. The call interruption method in the narrowband ad hoc network in the multi-station scenario of fig. 4 may include the steps of:
