The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

Fig. 1 is a flowchart illustrating a calling method of a narrowband private network according to an embodiment of the present application. As shown in fig. 1, an embodiment of the present application provides a method for calling a narrowband private network, which is applied to a receiving terminal, and the method includes the following steps:

step S101, call service data on a plurality of time slots of a time division multiple access frame corresponding to the current working frequency point is obtained.

In this embodiment, the main execution body for executing the corresponding call method is a receiving party in a terminal corresponding to a narrow-band private network, and is defined as a receiving terminal, and receives and analyzes call voice data corresponding to voice speech initiated by a plurality of different sending terminals (a sending party and a requesting party) at different time slots, thereby realizing simultaneous multi-person speech.

In this embodiment, the corresponding narrowband ad hoc network system includes, but is not limited to, a Time Division Multiple Access (TDMA) system; in this embodiment, the multiple timeslots are multiple timeslots of a TDMA frame corresponding to a current operating frequency point of a TDMA system corresponding to the embodiment of the present application, and the multiple timeslots referred to in the embodiment of the present application are double timeslots of a TDMA frame corresponding to a Digital trunked communication standard (DMR)/Police Digital Trunking (PDT), that is, a PDT/DMR call service divides a channel into two alternating timeslots, so that two logical channels are established in one physical channel; in this embodiment, the plurality of timeslots may be divided into a current timeslot and an adjacent timeslot, but the current timeslot and the adjacent timeslot are not limited to the timeslots in this embodiment, and are merely used to distinguish and refer to two timeslots; in some optional embodiments, the multiple timeslots and the call method according to the present application are also applicable to four timeslots corresponding to a european Trunked Radio (TETRA).

In this embodiment, the obtained call service data is service data on multiple time slots at the current working frequency point that is simultaneously received by the receiving terminal, and the service data on the corresponding time slot includes a call to the receiving terminal, a call to another terminal, and other related service data for communicating with the related terminal, for example: short messages.

Step S102, a first target call is detected in the call service data, wherein the first target call is used for representing a call to a receiving terminal.

In this embodiment, after the receiving terminal receives the call service data on the corresponding timeslots, the target call for itself is analyzed from all the received call service data, that is, the first target call is detected.

In this embodiment, the receiving terminal detects the call service data corresponding to each time slot of the call service data, and when detecting that there is a call to itself in a corresponding time slot, accesses the first target call in time, and then detects the call service data corresponding to other time slots, thereby detecting all target calls for the receiving terminal.

Step S103, a plurality of first target calls detected from the call service data are accessed.

In this embodiment, after the corresponding first target call is detected, the detected first target call needs to be accessed in time.

Step S104, after at least one first target call is selected from the plurality of first target calls, playing the call service data corresponding to the selected at least one first target call.

In this embodiment, the multiple first target calls may be multiple voice utterances of the same group call, which are performed by different group members in the same call group in multiple time slots of one tdma frame, or may be different calls, and the different calls may be a new group call or a single call. Specifically, the receiving terminal may receive call service data of one group call and one single call at the same time, may receive call service data of two different group calls at the same time, and may receive call service data of two different group members in the same call group speaking at the same time.

In this embodiment, when all calls directed to the receiving terminal are detected from the call service data, that is, after a plurality of first target calls are detected, the call service data corresponding to the plurality of first target calls are subjected to audio superposition and audio mixing, so that the receiving terminal receives the speech of multiple persons; of course, in this embodiment, after detecting the plurality of first target calls, only voice speech of a certain member or call service data of a certain group call may be received according to selection of the user holding the receiving terminal for the plurality of first target calls, so that the played call service data is at least call service data corresponding to one path of first target calls.

Through the steps from S101 to S104, call service data on a plurality of time slots of a time division multiple access frame corresponding to the current working frequency point is acquired; detecting a first target call in the call service data, wherein the first target call is used for representing a call to a receiving terminal; accessing a plurality of first target calls detected from the call service data; after at least one first target call is selected from the multiple first target calls, the call service data corresponding to the selected at least one first target call is played, so that the problems that the call working mode of the narrow-band private network is easy to miss important calls, group calls cannot talk at the same time and the communication efficiency of the group calls is low are solved, the purpose that multiple persons can talk at the same time in the narrow-band private network is achieved, the important calls are prevented from being missed, and the beneficial effects of user experience are improved.

It should be noted that, in the embodiment of the present application, by redesigning the call workflow, multiple users are allowed to talk simultaneously, multiple calls can be received simultaneously, multiple users in the same group can talk simultaneously, multiple voices can be received and analyzed simultaneously through multiple time slots, and then voices analyzed through different time slots are played in a set manner, for example: the audio is superposed and mixed, and then played, and the user can select and switch the call to be listened and called back according to the own needs.

It should be further noted that, in this embodiment, when a member of the same call group is speaking in voice, other members in the same call group may select to speak simultaneously in an idle timeslot of a tdma frame corresponding to the current operating frequency point, and when no idle timeslot is available, may select to wait for an idle timeslot; a receiving terminal needs to receive a plurality of call service data on different time slots of a current working frequency point at the same time, and if the receiving terminal corresponding to the corresponding call service data is the receiving terminal (namely, the destination of the call service data), the call service data corresponding to the multi-path first target call can be decoded and mixed to play; in this embodiment, the call service data in different time slots may be the speech of different members in different calls, or the speech of different members in the same group call; in this embodiment, when the receiving terminal receives a plurality of call service data, it may select to listen to only one of the call service data as needed, and the call service data of other paths are muted temporarily, and the receiving terminal may also switch to other voice paths as needed to listen; in this embodiment, when receiving multi-call service data of different groups, the receiving terminal may, according to a preset callback policy, for example: and the default callback is the group call received firstly, or the latest received group call, or a group call corresponding to a certain appointed group call and a certain path of selected call service data which is only received.

In some embodiments, after accessing a plurality of first target calls detected from the call service data, the following steps are further performed:

and step 21, judging whether the plurality of first target calls belong to the same call to obtain a judgment result, wherein the same call is used for representing that the sending terminal corresponding to the first target call is a group member in the same target call group.

In this embodiment, the same call means that the sending terminals of a plurality of first target calls are in the same call group, and meanwhile, the receiving terminal also belongs to the same call group.

In this embodiment, when the receiving terminal detects a call to itself in one of the multiple timeslots, the receiving terminal accesses the first target call in time, then detects whether there is a call to itself in another timeslot, and determines whether the call detected in another timeslot and the previous detected call belong to the same call.

And step 22, determining a second target call to be called back in the plurality of first target calls based on the judgment result.

In this embodiment, based on the determination result, it is determined whether a plurality of first target calls belong to the same call, so as to determine an object to be called back, for example: when a plurality of first target calls belong to the same call, the call back is the same call, namely, the call back is carried out on all group members during the call back; when a plurality of first target calls do not belong to the same call, one call can be selected for callback.

And step 23, sending the calling voice data to the sending terminal corresponding to the second target call so as to call back the corresponding sending terminal.

In this embodiment, after the second target call to be called back is determined, the calling voice data is sent back to the sending terminal corresponding to the second target call, so as to implement the corresponding call back.

Judging whether a plurality of first target calls belong to the same call or not to obtain a judgment result, wherein the same call is used for representing that a sending terminal corresponding to the first target call is a group member in the same target call group; determining a second target call to be called back in the plurality of first target calls based on the judgment result; and the calling voice data is sent back to the sending terminal corresponding to the second target call so as to call back the corresponding sending terminal, thereby realizing the judgment of judging whether a plurality of first target calls belong to the same call and the confirmation of a call back object.

It should be noted that, in this embodiment of the present application, after a plurality of first target calls are detected, it is determined whether the plurality of first target calls are utterances of different group members in the same group call or belong to a plurality of different calls, and then, according to a determination result, a sender of call service data received correspondingly is determined, so as to determine a defined scene in which multiple persons speak at the same time, and further to specify an object to call back. For example: when the first target calls are the voice speeches of a plurality of members under the same group call, the receiving terminal calls back the group call, and all the members under the corresponding group call are called back; another example is: when the plurality of first target calls are a plurality of different calls and the receiving terminal makes a callback, one call can be selected from the plurality of different calls to make the callback.

In some embodiments, determining whether a plurality of the first target calls belong to the same call is implemented by:

step 31, obtaining call service data corresponding to a plurality of first target calls to obtain target service data, wherein the target service data includes corresponding sending terminal information and/or group call identification information.

And step 32, judging whether the sending terminals corresponding to the first target calls are members of the same target call group according to the corresponding sending terminal information and/or group call identification information, and obtaining a judgment result.

In this embodiment, whether a plurality of first target calls belong to the same call is determined by determining a sender of corresponding call service data and determining whether a distributor belongs to a group member of the same call group; in this embodiment, the sender of the call service data is determined according to the destination information of the sender. For example: the corresponding sender is determined by sending the terminal information of the terminal and the group identification information corresponding to the calling group to which the terminal belongs, namely the group calling identification information.

Obtaining target service data by obtaining call service data corresponding to a plurality of first target calls in the steps, wherein the target service data comprises corresponding sending terminal information and/or group call identification information; and judging whether the sending terminals corresponding to the first target calls are members of the same target call group or not according to the corresponding sending terminal information and/or group call identification information, obtaining a judgment result, and realizing the determination of the composition of the correspondingly received call service data, thereby determining a defined scene in which multiple persons talk simultaneously, so as to clearly correspond to the object for calling back, and further realizing the simultaneous talking of the multiple persons.

In some embodiments, based on the determination result, a second target call to be called back is determined in the plurality of first target calls, and the method includes the following steps:

and step 41, determining that the second target call is the first target call under the condition that the judgment result shows that the plurality of first target calls belong to the same call.

In this embodiment, if the call detected in other time slots is the same call as the previous call, which indicates that the call is a scenario in which multiple people are speaking at the same time in the same call, the second target call determined to be called back is the current first target call.

And 42, under the condition that the judgment result shows that the plurality of first target calls do not belong to the same call, selecting one call from the plurality of first target calls as a second target call according to a preset callback strategy, and calling back a sending terminal corresponding to the second target call.

In this embodiment, when the calling method of the narrow-band private network according to the embodiment of the present application is applied to a PDT/DMR system, the corresponding multiple time slots are current time slots and adjacent time slots, and the multiple first target calls do not belong to the same call, which includes two-way group calling, one-way single calling, and one-way group calling; when applied to the TETRA system, the corresponding multiple timeslots are four timeslots, and the multiple first target calls do not belong to the same call, which includes the following two cases: first, the four first target calls are all different calls (e.g., four group calls); second, two of the four first target calls belong to the same call, and the other two first target calls are calls different from the previous one.

In this embodiment, if the call detected in other timeslots is not the same call as the previous call, it is determined that a scenario of multiple different calls being accessed simultaneously, and a callback may be performed based on the selected first target call of the user.

Determining the second target call as the first target call under the condition that the judgment result in the step is that a plurality of first target calls belong to the same call; and under the condition that the judgment result shows that the plurality of first target calls do not belong to the same call, selecting one call from the plurality of first target calls as a second target call according to a preset callback strategy, and calling back a sending terminal corresponding to the second target call to realize the determination of callback objects under different call scenes.

In some embodiments, selecting one call from a plurality of first target calls as a second target call according to a preset callback policy, and calling back a sending terminal corresponding to the second target call, may be implemented by: taking a first target call corresponding to the currently played call service data as a second target call, and calling back a sending terminal corresponding to the second target call; or the like, or, alternatively,

one of the first target calls is designated as a second target call according to preset conditions, and a sending terminal corresponding to the second target call is called back, wherein the preset conditions comprise one of the following conditions: time sequence of call access, call priority sequence.

In this embodiment, the receiving terminal may select a path to call back according to a call back policy corresponding to a preset condition. For example: when calling back according to the time sequence of call access, calling back the first accessed group call; and when the call back is carried out according to the call priority sequence, selecting a first target call with the highest call priority for replying.

Taking the first target call corresponding to the currently played call service data as a second target call, and calling back a sending terminal corresponding to the corresponding second target call; or, one of the first target calls is designated as a second target call according to a preset condition, and the corresponding sending terminal of the second target call is called back, so that the confirmation of the call-back object is realized.

In some embodiments, the playing the call service data corresponding to the selected at least one first target call includes the following steps: and performing sound mixing processing on the call service data corresponding to the at least two selected first target calls, and playing the call service data subjected to the sound mixing processing.

In this embodiment, the process of the receiving terminal performing the mixing processing on the call service data is as follows: the method comprises the steps of firstly respectively decoding call service data corresponding to at least two selected first target calls into PCM format voice, then overlapping and mixing the decoded voice, and generating a path of PCM format voice after overlapping, wherein the path of PCM format voice corresponds to the played call service data.

Fig. 2 is a schematic diagram of a simulation effect after audio is subjected to superposition and audio mixing processing provided in the preferred embodiment of the present application, in some possible embodiments, two-path call service data is subjected to superposition and audio mixing processing, and a corresponding simulation result is shown in fig. 2.

In some embodiments, the playing of the call service data corresponding to the selected at least one first target call may be further implemented by the following steps: according to a preset playing strategy, selecting call service data corresponding to one of the first target calls to play, wherein the preset playing strategy comprises one of the following: time sequence of call access, call priority sequence.

In this embodiment, the receiving terminal may listen based on its selection, that is, selectively play according to the corresponding play policy, for receiving a plurality of first target calls for itself. For example: when the calling service data is played according to the time sequence of call access, the calling service data corresponding to the first accessed group call is played, and when the calling service data is played according to the call priority sequence, the calling service data corresponding to a first target call with the highest call priority is selected for playing.

Fig. 3 is a schematic flowchart of a calling method for a narrowband private network according to a preferred embodiment of the present application, and referring to fig. 3, the flowchart includes:

step 51, in the receiving process, call service data on a plurality of time slots corresponding to one time division multiple access frame under the current working frequency point needs to be received and analyzed simultaneously.

If a first call (a first target call) to the receiving terminal is detected in one of the time slots, step 52, the first call needs to be accessed in time.

And step 53, continuing to detect the call service data on other adjacent time slots.

If it is detected in other time slots that the call traffic data in other adjacent time slots has a second call (another first target call) to the receiving terminal, step 54, the second call needs to be accessed at the same time.

And step 55, if the second call and the first call are the same call, corresponding to a scene that a plurality of members in the same group call speak at the same time, the user can select to play a plurality of call service data in a superposition manner, and can also select to only listen to the corresponding call according to the requirement. Since it is the same call, the call back is the current call.

Step 56, if the second call is not the same call as the first call, corresponding to a scenario where a plurality of different calls are simultaneously accessed, the user may select to play the multi-channel audio in a superimposed manner, or may select to listen to only the call service data of one of the calls as needed. When calling back, one of the calls can be appointed to call back, and the currently listened call can be selected to call back.

Fig. 4 is a flowchart illustrating a calling method of a narrowband private network according to an embodiment of the present application. As shown in fig. 4, an embodiment of the present application provides a method for calling a narrowband private network, which is applied to a sending terminal, and the method includes the following steps:

step S401, when a first target call is received in the current time slot, determining whether the first target call has the authority of multi-person speaking of a group corresponding to the first target call, wherein the first target call is used for representing a call to a receiving terminal.

In this embodiment, the execution main body for executing the corresponding call method is a sender in a terminal, defined as a sending terminal, and calls the same receiving terminal (receiver, destination) through different group members in a plurality of same call groups, thereby realizing simultaneous multi-person speech in the same group call.

In this embodiment, the corresponding narrowband ad hoc network system includes, but is not limited to, a Time Division Multiple Access (TDMA) system; in this embodiment, the multiple timeslots are multiple timeslots of a TDMA frame corresponding to a current operating frequency point of a TDMA system corresponding to the embodiment of the present application, and the multiple timeslots referred to in the embodiment of the present application are double timeslots of a TDMA frame corresponding to a Digital trunked communication standard (Digital mobile Radio, DMR for short)/police Digital Trunking (PDT for short), that is, a PDT/DMR call service divides a channel into two alternate timeslots, so that two logical channels are established in one physical channel; in this embodiment, the plurality of timeslots may be divided into a current timeslot and an adjacent timeslot, but the current timeslot and the adjacent timeslot are not limited to the timeslots in this embodiment, and are merely used to distinguish and refer to two timeslots; in some optional embodiments, the multiple timeslots and the call method according to the present application are also applicable to four timeslots corresponding to a european Trunked Radio (TETRA).

In this embodiment, the first target call received at the current time is a call that characterizes that the corresponding sending terminal receives and listens to the call sent by the terminals in the same call group to the corresponding receiving terminal (terminals belonging to the same call group) at the current time slot. After receiving the first target call, if a sending terminal executing the method of the embodiment of the present application wants to initiate a speech to a receiving terminal corresponding to the first target call, that is, send the first target call to the receiving terminal corresponding to the first target call, it needs to detect whether the sending terminal has an authority to perform a multi-person speech in a group call corresponding to the first target call before sending the first target call, that is, it determines whether the corresponding sending terminal allows the multi-person speech to be performed in the corresponding group call.

Step S402, under the condition that the adjacent time slots have the authority of speaking more than one person, whether the adjacent time slots are idle is detected.

In this embodiment, when it is determined that the sending terminal has the authority to speak for multiple persons, it is further required to detect whether there is an idle time slot in multiple time slots of a tdma frame corresponding to the current working frequency point, where two adjacent time slots of the multiple time slots are the current time slot and adjacent time slots; in this embodiment, when the first target call is received, it indicates that the current timeslot is busy, that is, is temporarily used, and at this time, it is necessary to obtain the corresponding talk right by detecting whether the adjacent timeslot is idle.

Step S403, when detecting that the adjacent time slot is idle, sending the first target call to the receiving terminal in the adjacent time slot.

In this embodiment, when it is detected that the adjacent time slot is idle, at this time, the sending terminal allows initiating voice speech to the receiving terminal in the adjacent time slot, so that the terminal sending the first target call in the current time slot and the sending terminal sending the first target call in the adjacent time slot perform voice speech with the receiving terminal at the same time.

In this embodiment, the terminal that sends the first target call in the current timeslot, the sending terminal that sends the first target call in the adjacent timeslot, and the receiving terminal may be different group members in the same call group, that is, the voice speech initiated by the sending terminal is the voice speech performed by different members under the corresponding group call, and at this time, the receiving terminal receives the speech of different members in the call group of the same group call in different timeslots.

Through the steps S401 to S403, when receiving a first target call at the current time slot, determining whether the first target call has the permission of speaking for multiple persons in a group corresponding to the first target call, where the first target call is used to represent a call to a receiving terminal; under the condition that the system has the authority of speaking multiple persons, detecting whether the adjacent time slot is idle or not; when the idle time of the adjacent time slot is detected, the first target call is sent to the receiving terminal in the adjacent time slot, the problems that important calls are easily missed due to the call working mode of the narrow-band private network, group calls cannot talk at the same time, and the communication efficiency of the group calls is low are solved, the situation that multiple persons are allowed to talk at the same time in the narrow-band private network is achieved, the important calls are prevented from being missed, and the beneficial effect of user experience is improved.

In some embodiments, after determining whether the first target call has the authority of speaking more than one person in the corresponding group, the following steps are further implemented: in a case where it is determined that there is no authority to speak of plural persons, it is determined that the first target call is not allowed to be transmitted to the receiving terminal.

In this embodiment, when it is determined that the corresponding sending terminal does not have the multi-person speaking right of the corresponding group, it is not necessary to determine whether the adjacent time slot is idle, and it may be directly determined that the first target call cannot be sent to the receiving terminal.

In some of these embodiments, upon detecting that the adjacent time slot is busy, the following steps are also performed:

step 71, detecting whether the device has the arbitration authority for interrupting the speaking right.

And 72, when detecting that the terminal has the speaking right arbitration limit, interrupting the first target call sent to the receiving terminal in one time slot, sending the first target call to the receiving terminal in the time slot, and carrying out multi-person speaking with the terminal of the first target call sent to the receiving terminal in other time slots in a plurality of time slots.

In this embodiment, when it is detected that the adjacent time slot is occupied, if it is important that the sending terminal expects to perform the voice speech to be initiated, the sending terminal sends the first target call to the receiving terminal after interrupting calls in other time slots.

Whether the detection in the steps is used for interrupting the arbitration authority of the speaking right or not is detected; when detecting that the terminal has the speaking right arbitration limit, interrupting a first target call sent to a receiving terminal in one time slot, sending the first target call to the receiving terminal in the time slot, and carrying out multi-person speaking in a plurality of time slots with the terminal of the first target call sent to the receiving terminal in other time slots, so as to realize starting emergency calling speaking when the adjacent time slots are busy.

Fig. 5 is a schematic flowchart of a calling method of a narrowband private network according to a preferred embodiment of the present application, and with reference to fig. 5, the flowchart includes:

step S501, detecting whether the current time slot is busy, if yes, executing step S502, otherwise, executing step S505.

Step S502, whether the user has the authority of speaking multiple persons is detected, if yes, step S503 is executed, otherwise, step S504 is executed.

Step S503, detecting whether the adjacent time slot is idle, if yes, executing step S505, otherwise, executing step S506.

Step S504, refusing the sending terminal to send the first target call to the receiving terminal.

And step S505, initiating voice speaking in the corresponding idle time slot.
