Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, 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 invention.
The embodiment of the invention discloses a call service processing method, which is applied to a first terminal with a link authorization authority in a group call service.
Specifically, in the group call service, a plurality of terminals transmit call service data through a service channel of the group call service, and only two time slots of one service channel may be used for transmitting the service data. In order to prevent a plurality of terminals from transmitting service data through an idle time slot at the same time to cause service collision and service data intersection, in the embodiment of the present invention, a link authorization authority is set in a group call service, and the link authorization authority is given to one of the terminals which are transmitting call service data in the group call service, that is, the first terminal, and the first terminal authorizes other terminals in the group call service to occupy the idle time slot to transmit the call service data.
Referring To fig. 1, when the first terminal initiates a group call service, a full duplex group call is initiated by pressing a PTT (Push To Talk) button on the terminal, and a service data frame carrying a special frame of the full duplex group call is sent while occupying a first time slot in a service channel of the group call service, so as To indicate that the call is the full duplex group call, that is, the first terminal sends call service data through the first time slot of the service channel of the group call service.
Because the embodiment of the invention sets the link authorization for the group calling service, when other terminals receive the calling service data sent by the first terminal through the first time slot of the service channel and need to send the data, the other terminals can only select the second time slot of the service channel to send the response data under the condition that the second time slot of the service channel is idle. And, after confirming that the second time slot of the traffic channel is idle, first sending link access request information to the first terminal having the link authorization authority.
Because the terminal can directly send the group calling service data under the condition of not pressing the PTT key of the terminal in advance, when the user speaks to the voice collector of the terminal, the terminal starts to collect the voice data of the user, and simultaneously sends the link access request information autonomously, and then continues to send the voice data of the user after obtaining the link access permission, otherwise, the user is prompted that the service data can not be sent at the moment.
Referring to fig. 2, when the first terminal receives the link access request information sent by the second terminal in the group call, step S201 is executed to detect whether the second terminal is allowed to send call service data through the second timeslot of the traffic channel;
specifically, since the first terminal already occupies the first time slot of the group call traffic channel to transmit the call traffic data, the second terminal can only request to transmit the call traffic data through the second time slot of the traffic channel. When the second terminal prepares to send the call service data, it needs to detect in advance which time slot of the group call service channel is idle, and then sends the link access request information requesting to occupy the time slot. Therefore, the link access request information received by the first terminal and sent by the second terminal is actually the request information sent by the second terminal to occupy the second time slot of the group call traffic channel when the second terminal detects and confirms that the second time slot of the group call traffic channel is idle.
Correspondingly, after receiving the link access request information sent by the second terminal, the first terminal detects whether the second terminal is allowed to send the call service data through the second time slot of the service channel.
Specifically, the specific processing procedure of the first terminal detecting whether to allow the second terminal to send the call service data through the second timeslot of the service channel may be implemented by referring to a common service access authentication manner, for example, the first terminal detects whether the second terminal is a legal terminal, detects whether the second timeslot of the service channel is idle, and the like.
If the detection confirms that the second terminal is allowed to send the call service data through the second time slot of the traffic channel, step S202 is executed to send response information indicating that the call service data can be sent through the second time slot of the traffic channel to the second terminal, so that the second terminal sends the call service data through the second time slot of the traffic channel.
Specifically, when the first terminal determines that the second terminal can occupy the time slot to send the call service data, the first terminal sends response information indicating that the call service data can be sent through the second time slot of the service channel to the second terminal, that is, the second terminal is authorized to occupy the second time slot of the service channel. At this time, the second terminal may transmit call service data through the second slot of the traffic channel.
If the first terminal finds that the second time slot of the service channel at the current time is occupied by other terminals through detection, the first terminal does not respond to the link access request information sent by the second terminal, the second terminal does not receive the response of the first terminal within the set waiting time, the second terminal feeds back the fact that the current time cannot send voice to the user, and the second terminal can only continue to receive the call service data sent by the first terminal through the first time slot of the service channel. And when the second terminal user needs to send the voice data again and detects that the second time slot of the service channel is idle, triggering the second terminal to send the link access request information to the first terminal again to request the use permission of the second time slot of the service channel.
Optionally, before the second terminal sends the link access request to the first terminal, it may first detect whether there is an idle timeslot in the traffic channel, that is, detect whether the second timeslot of the traffic channel is idle, and send the link access request information to the first terminal only when the idle timeslot, that is, the second timeslot is idle, is detected. Therefore, when the first terminal receives the link access request information sent by the second terminal, it may default that the second time slot is idle at the current time, and therefore the first terminal may omit the above step S201 and directly execute step S202.
The step S201 is configured to mainly avoid that when a plurality of terminals simultaneously transmit the link access request information or an illegal terminal transmits the link access request information, the first terminal can perform control on service access of other terminals, so as to ensure the order of the call service.
It should be noted that, when the second terminal is a plurality of terminals, that is, a plurality of terminals simultaneously transmit a link access request to request the usage right of the second timeslot of the traffic channel, the first terminal selects one terminal from the plurality of terminals according to a preset rule to transmit response information indicating that the call traffic data can be transmitted through the second timeslot of the traffic channel. For example, it is possible to transmit response information indicating that call service data can be transmitted through the second slot of the traffic channel to a terminal having a higher priority by identifying the priority of a terminal simultaneously transmitting a link access request.
An optional mode is that, when the first terminal sends the response message to the second terminal, the response message is sent simultaneously with the call service data sent by the first terminal in the first time slot of the traffic channel, and since the second terminal is also monitoring the service data in the first time slot, the second terminal can receive the response message while receiving the service data.
For example, as shown in fig. 3, it is assumed that terminal a is occupying a first time slot of a traffic channel to transmit voice data, and when terminal B needs to occupy a second time slot of the traffic channel to transmit voice data, it first transmits link access request information to terminal a through the second time slot. After receiving the request message, if the terminal a determines that the second time slot is idle and can be allocated to the terminal B to occupy, the terminal a carries the sending authorization response message when sending voice data through the first time slot next time, and notifies the terminal B that the voice data can be sent through the second time slot. Then terminal A occupies the first time slot to send voice data, terminal B occupies the second time slot to send voice data, and other terminals which can not send voice data can receive two paths of voice through the first time slot and the second time slot of the service channel.
As can be seen from the above description, in the embodiment of the present invention, a link authorization right is set for a first terminal that sends call service data through a first time slot of a service channel in a group call service, and when the first terminal receives a link access request message sent by a second terminal in the group call, a response message indicating that the call service data can be sent through a second time slot of the service channel is sent to the second terminal, so that the second terminal sends the call service data through the second time slot of the service channel. The technical proposal gives the access control processing of the group calling service to the first terminal in the group calling service for execution, thereby simplifying the structure of the whole group calling service system and controlling the calling service more flexibly.
It can be understood that, since the embodiment of the present invention sets the link authorization authority for the group call service, and assigns the authority to the first terminal which transmits the call service data through the first time slot of the group call service channel for exercise. When other terminals need to occupy the second time slot of the group calling service channel to send data, the other terminals need to pass through the link authorization of the first terminal to occupy the second time slot, so that collision or data crossing caused by the plurality of terminals occupying the second time slot can be avoided.
However, the first terminal does not always maintain the first time slot of the traffic channel to send the call service data, and the embodiment of the present invention sets that, when the first terminal stops sending the call service data, the first terminal should stop occupying the first time slot of the traffic channel, and give the link authorization authority to other terminals occupying the second time slot, and when the first terminal needs to occupy the idle time slot again to send the call service data, the first terminal requests the terminal having the link authorization authority to occupy the idle time slot.
On the basis of the call service processing method with link authorization authority shown in fig. 2, the embodiment of the present invention further provides a technical solution for link authorization authority handover and link maintenance processing.
Referring to fig. 4, the call service processing method disclosed in the embodiment of the present invention further includes:
when the first terminal stops sending the call service data, executing step S403, detecting whether a terminal is sending the call service data through the second timeslot of the traffic channel;
specifically, in the embodiment of the present invention, when the first terminal stops sending the call service data, that is, the first time slot of the service channel of the group call service is no longer occupied, in order to facilitate occupation by other terminals that are needed, the first terminal should release the first time slot and quit sending the data. However, since the embodiment of the present invention configures the link authorization right for the call service and gives the authorization right to the first terminal for execution, the first terminal takes on the responsibility of allocating the link access right to other terminals in the group call service, and if the first timeslot directly exits from the first timeslot, the first terminal cannot allocate the link access right to other terminals, thereby affecting the call service data transmission of other terminals.
In order to keep executing the link authorization process all the time in the group call service, the embodiment of the present invention sets that, when the first terminal stops sending the call service data, it first detects whether there is a terminal sending the call service data through the second time slot of the service channel of the group call service, that is, detects whether there is a terminal occupying the second time slot of the service channel to make a service call.
If a terminal is sending call service data through the second time slot of the service channel, executing step S404, transferring the link authorization authority to the terminal sending call service data through the second time slot of the service channel;
specifically, when the first terminal determines that the terminal is transmitting the call service data in the second time slot of the traffic channel, the first terminal transfers the link access authorization right owned by the first terminal to the terminal transmitting the call service data in the second time slot of the traffic channel.
The first terminal transfers the link authorization authority to the second terminal in a request and response interactive mode with the second terminal.
Referring to fig. 5, after the first terminal a finishes transmitting voice in the first time slot of the traffic channel, it is detected that the second terminal B transmits voice data in the second time slot of the traffic channel. The first terminal a sends the authorized handover request information through the first time slot, and when the second terminal B receives the authorized handover request information sent by the first terminal a through the first time slot, the authorized handover response information is sent through the second time slot, and the response information represents that the link authorization authority can be transferred to the second terminal B. When the first terminal a receives the authorization transfer response message through the second time slot, it is determined that the link authorization authority has been transferred to the second terminal B, and the transmission of the voice data may be stopped, and the first time slot may be released.
If no terminal is sending call service data through the second time slot of the service channel, the first terminal executes step S405 and keeps sending an occupied channel data frame through the first time slot of the service channel within a set time length;
specifically, when the first terminal stops sending the call service data through the first time slot of the service channel of the group call service, if it is found through the judgment that no terminal is sending the call service data in the second time slot of the service channel, the first terminal cannot transfer the originally owned link authorization authority to other terminals. However, no terminal sends the call service data through the traffic channel timeslot at the current time, and does not mean that no terminal wants to send the call service data through the traffic channel timeslot at a later stage. When a terminal in the group call service wants to send call service data again, the group call service should have the right to use the traffic channel.
In order to maintain the right of the group call service to use the service channel, so that the terminal in the group call service can smoothly occupy the service channel when sending the call service data again in the later period, the embodiment of the present invention sets that, when the first terminal stops sending the call service data through the first time slot of the service channel of the group call service, and detects and determines that no terminal is sending the call service data in the second time slot of the service channel, the first terminal sends a data frame of the occupied channel in the first time slot of the service channel, and continuously sends the set duration.
That is to say, when the last terminal having the link authorization authority in the group call service is set to stop sending the call service data, the embodiment of the present invention first keeps sending the occupied channel data frame within the set time length so as to maintain the located service channel, so that when other terminals in the group call service want to send the call service data again within the set time length, the other terminals can directly occupy the service channel being maintained.
For example, as shown in fig. 6, assuming that the last terminal transmitting the call service data through the second time slot of the traffic channel also stops transmitting the call service data, the terminal transmits an occupied channel data frame, i.e., transmits link maintenance data, on the occupied second time slot, so as to prevent the traffic channel from being occupied by terminals of other services after being completely released. Accordingly, other terminals on the traffic channel may receive the link maintenance data through the second time slot.
It will be appreciated that embodiments of the invention set the link maintenance method to send a frame of occupied channel data on the link, rather than simply maintaining the link by means of a timer. If the link is maintained by a timer, other terminals may occupy the traffic channel if they detect that there is no data transmission on the channel without knowing that the timer exists. The embodiment of the invention sets the occupied channel data frame to be sent on the service channel to maintain the link, so that any terminal can detect that the data transmission exists on the service channel in the link maintenance stage, the service channel can not be occupied any more, and the real link maintenance is achieved.
In addition, the embodiment of the present invention sets that, within the set duration, if receiving a link access request message sent by a third terminal in the group call service, step S406 is executed to send a response message indicating that call service data can be sent through a second time slot of the service channel to the third terminal, and at the same time, the link authorization right is transferred to the third terminal, and sending an occupied channel data frame through the first time slot of the service channel is stopped;
specifically, in the set duration, in the process that the first terminal sends the occupied channel data frame through the first time slot of the service channel of the group call service, if the first terminal receives any terminal in the group call service, for example, receives the link access request information sent by the third terminal, the first terminal sends, to the third terminal, response information representing that the call service data can be sent through the second time slot of the service channel. When the first terminal sends the occupied channel data frame, only the first terminal is still occupying the channel, so that the second time slot of the traffic channel can be determined to be idle, and when receiving the link access request information sent by the third terminal, the first terminal can directly send the response information representing that the call traffic data can be sent through the second time slot of the traffic channel to the third terminal.
Meanwhile, the first terminal also transfers the link authorization authority to the third terminal, and the specific transfer process is implemented by referring to the link authorization transfer process shown in fig. 5, which is not described herein again.
And the first terminal stops transmitting the occupied channel data frame through the first time slot of the traffic channel, namely the first terminal really stops transmitting data. At this time, only the third terminal sends the call service data through the second time slot of the service channel of the group call service, and when the terminal wants to occupy the first time slot to send the call service data, the link authorization process of the third terminal needs to be implemented by referring to the method shown in fig. 2. And, when the third terminal does not transmit the call service data any more, it can also perform corresponding processing with reference to the method shown in fig. 4.
And in the set duration, if the link access request information sent by any terminal is not received, executing step S407, and stopping sending the occupied channel data frame after the set duration is over.
Specifically, within the set time length, if the first terminal does not receive the link access request information sent by any terminal, the first terminal stops sending the occupied channel data frame after the set time length is over, completely releases the traffic channel, and ends the group call service.
It can be seen from the above description that, in the embodiments of the present invention, by setting the link authorization authority for the group call service, and setting the link authorization authority, the forwarding can be performed between the service terminals, and setting the last terminal of the group call that stops sending the service data to maintain the link by sending the occupied channel data frame, so that the whole group call service is performed in order, collision of the occupied channel of the terminal is avoided, and the service channel can be effectively maintained.
Steps S401 and S402 in this embodiment correspond to steps S201 and S202 in the method embodiment shown in fig. 2, respectively, and for details, please refer to the contents of the method embodiment shown in fig. 2, which is not described herein again.
In another embodiment of the present invention, a call service processing method is further disclosed, and as shown in fig. 7, the method includes:
when call service data needs to be sent through an idle time slot of a service channel of a group call service, step S701 is executed, and link access request information is sent to a first terminal with link authorization authority in the group call service;

Specifically, the above technical scheme is applied to a group call service, and a terminal that needs to occupy a service channel to send service data is required.
In the embodiment of the invention, the link authorization authority is set for the group call service, except the first terminal initiating the group call service, other terminals which want to occupy the group call service channel to send service data need to request the use right of the idle time slot of the service channel from the terminal with the link authorization authority.
Referring to fig. 3, it is assumed that a terminal a has a link authorization right and occupies a first time slot of a group call traffic channel to transmit traffic data, and when a terminal B detects that a second time slot of the group call traffic channel is idle and needs to transmit the call traffic data through the idle second time slot of the traffic channel, first, the terminal a transmits link access request information to a first terminal having the link authorization right in the group call traffic, that is, the terminal a.
