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 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.
Before introducing the call processing method of the present application, the following description is made on the background of the present application:
when the calling terminal and the called terminal can perform normal communication, the flow of successfully establishing a call service between the calling terminal and the called terminal is shown in fig. 1: firstly, a calling terminal sends a calling request to a called terminal; the called terminal replies a confirmation message to the calling terminal after receiving the call request; after receiving the confirmation message, the calling terminal sends individual calling voice to the called terminal, thereby carrying out normal individual calling service.
However, when the calling terminal and the called terminal are too far away from each other or are affected by the environment, and the individual call request sent by the calling terminal cannot reach the called terminal, the individual call service between the calling terminal and the called terminal cannot be established, and the service flow at this time is as shown in fig. 2.
Based on the background, the present application provides a call processing method, which establishes an individual call service between a calling terminal and a called terminal through a relay function of an intermediate terminal, and can improve a success rate of the individual call service and extend a communication distance of the individual call service.
Referring to fig. 3, fig. 3 is a flowchart illustrating an embodiment of a call processing method according to the present application. The embodiment relates to three terminals, which are respectively defined as a first terminal, a second terminal and a third terminal, where the premise of the embodiment is that the third terminal and the first terminal can transmit and receive messages to and from each other, and the third terminal and the second terminal can also transmit and receive messages to and from each other, and the third terminal supports an intra-frequency relay mode, and meanwhile, the call processing method in the embodiment is executed by the third terminal, specifically, the method includes:
s110: and receiving a call request sent by the first terminal to the second terminal.
S120: and judging whether the second terminal replies the call request.
If the determination result is yes, the process proceeds to step S160, and if the determination result is no, the process proceeds to step S130.
S130: and starting the same-frequency transit mode and forwarding the call request to the second terminal.
S140: and when receiving the confirmation message of the second terminal replying the call request, forwarding the confirmation message to the first terminal.
S150: the call data is forwarded between the first terminal and the second terminal.
S160: and ending the flow.
Referring to fig. 4, when a first terminal wants to establish a call service with a second terminal, the first terminal first sends a call request to the second terminal, where the call request carries identifiers of the first terminal (i.e., a calling terminal) and the second terminal (i.e., a called terminal); because the first terminal and the third terminal can send and receive information to and from each other, the third terminal can also receive the call request, after the third terminal receives the call request, the third terminal analyzes the call request to obtain the identifications of the first terminal and the second terminal, then the third terminal judges whether the second terminal replies the call request within a preset time (such as 1S, 2S and the like) after receiving the call request, if the second terminal does not reply, the third terminal starts an intra-frequency relay mode to play a relay role between the first terminal and the second terminal, and when the second terminal successfully replies, the third terminal ends the flow and does not participate in the establishment of the call service between the first terminal and the second terminal.
After the third terminal starts the same-frequency relay mode, the third terminal forwards the call request sent by the first terminal to the second terminal, and after the second terminal receives the call request, if the second terminal is in an idle state, the second terminal sends a confirmation message (the confirmation message indicates that the second terminal is willing to communicate with the first terminal, and the confirmation message carries the identifiers of the first terminal and the second terminal) for replying the call request.
After the second terminal sends a confirmation message for replying the call request, the third terminal can receive the confirmation message, then the third terminal forwards the confirmation message to the first terminal, the first terminal authenticates through the identification carried by the confirmation message after receiving the confirmation message, then the first terminal can know that the confirmation message is returned by the second terminal aiming at the call request sent by the second terminal, and then the first terminal establishes a call service with the second terminal through the relay action of the third terminal.
In the above embodiment, when the first terminal and the second terminal cannot receive and transmit information, the third terminal starts the same-frequency relay mode to perform a relay function between the first terminal and the second terminal, so as to indirectly realize communication between the first terminal and the second terminal, thereby improving the success rate of the individual call service and extending the communication distance of the individual call service.
In this embodiment, step S150 specifically includes:
s151: after receiving the calling voice sent by the first terminal, forwarding the calling voice to the second terminal.
Specifically, after the first terminal receives the confirmation message sent by the second terminal and forwarded by the third terminal, the first terminal, as the calling terminal, sends a calling voice to the second terminal, and then the third terminal, as a relay, forwards the calling voice to the second terminal.
With reference to fig. 4, in an application scenario, the step of forwarding the call voice to the second terminal by the third terminal specifically includes: after receiving the voice frame sent by the first terminal, the third terminal forwards the voice frame to the second terminal if the voice frame is not the last voice frame in the calling voice; and if the voice frame is the last voice frame in the calling voice, forwarding the voice frame to the second terminal, and closing the same-frequency transit mode after forwarding.
Specifically, when the voice frame received by the third terminal is not the last frame in the call voice, the third terminal directly forwards the voice frame to the second terminal, and when the voice frame received by the third terminal is the last frame in the call voice, the third terminal also closes the same-frequency transit mode after forwarding the voice frame to the second terminal.
That is, when the last frame is not received, the third terminal forwards each frame of voice frame, and when the last frame is received, the third terminal closes the same-frequency transit mode after forwarding, that is, after the call voice is successfully forwarded, the third terminal closes the same-frequency transit mode.
In the application scenario, after the third terminal confirms that the call voice is successfully forwarded, the same-frequency transit mode is closed, and then the third terminal does not play a relay role any more and can be used as a conventional terminal.
In this embodiment, step S150 further includes:
s152: and after receiving the callback voice which is sent by the second terminal in the hang-up time and serves as the response individual call voice, starting the same-frequency transit mode.
S153: and forwarding the callback voice to the first terminal.
After receiving the call voice forwarded by the third terminal, if the second terminal sends a call-back voice as a reply to the call voice within the hang-up time hangtime, the third terminal restarts the same-frequency relay mode after receiving the call-back voice, and forwards the call-back voice to the first terminal, that is, the third terminal continues to play a role of relay between the first terminal and the second terminal.
With reference to fig. 4, in an application scenario, the step of forwarding the callback voice to the first terminal by the third terminal specifically includes: after receiving the voice frame sent by the second terminal, the third terminal forwards the voice frame to the first terminal if the voice frame is not the last voice frame in the callback voice; and if the voice frame is the last voice frame in the callback voice, forwarding the voice frame to the first terminal, and closing the same-frequency transit mode after forwarding.
Specifically, similar to the above-mentioned receiving of the individual call voices, when the voice frame received by the third terminal is not the last frame in the callback voice, the third terminal directly forwards the voice frame to the first terminal, and when the voice frame received by the third terminal is the last frame in the callback voice, the third terminal also closes the same-frequency relay mode after forwarding the voice frame to the first terminal.
That is, when the last frame is not received, the third terminal forwards each frame of voice frame, and when the last frame is received, the third terminal closes the same-frequency transit mode after forwarding, that is, after the callback voice is successfully forwarded, the third terminal closes the same-frequency transit mode.
In the application scenario, after the third terminal confirms that the callback voice is successfully forwarded, the same-frequency transit mode is closed, and then the third terminal does not play a relay role any more and can be used as a conventional terminal.
In this embodiment, the third terminal also starts the virtual cluster mode each time after the same-frequency relay mode is turned off.
Specifically, after the virtual cluster mode is started, the third terminal can receive messages in both time slots, and when one time slot is busy, the third terminal automatically uses the other time slot to work, so that the success rate of communication service can be improved.
In this embodiment, the step of the third terminal determining whether the second terminal replies the individual call request includes: and the third terminal monitors the air interface message to judge whether the second terminal replies a call request within a preset time after receiving the call request sent by the first terminal to the second terminal.
That is, the third terminal determines whether the second terminal replies to the individual call request of the first terminal by monitoring the air interface message.
The preset time may be designed by a designer, for example, 30 milliseconds, 1 second, or 2 seconds.
The first terminal, the second terminal, and the third terminal according to the present embodiment are the same type of devices, and are all interphones. In other embodiments, the first terminal, the second terminal, and the third terminal may be other devices of the same type, such as a mobile phone, or may be different types of devices, such as a part of terminals being walkie-talkies and a part of terminals being mobile phones. In summary, no limitation is made herein as to what kind of device the first terminal, the second terminal, and the third terminal are.
In the method, under the application scene that the third terminal and the first terminal can receive and transmit messages mutually, the third terminal and the second terminal can also receive and transmit messages mutually, and the first terminal and the second terminal cannot receive and transmit messages mutually, the individual calling service between the first terminal and the second terminal can be established through the relay action of the third terminal, and the communication distance of the individual calling service is prolonged.
However, in real life, the following scenarios also exist:
first, as shown in fig. 5 (for clarity of the drawings, in fig. 5 to 7, a reference sign a represents a first terminal, a reference sign B represents a second terminal, and a reference sign C represents a third terminal), two of the first terminal, the second terminal, and the third terminal are within a range capable of receiving and sending information to and from each other, at this time, after the first terminal sends a call request to the second terminal, the second terminal can receive the call request, and then the second terminal replies the call request, normal communication is performed between the first terminal and the second terminal, in this process, for the third terminal, it monitors that the second terminal replies the call request sent by the first terminal, and therefore, it does not participate in the communication between the first terminal and the second terminal, and the third terminal is only a common conventional terminal.
Second, as shown in fig. 6, a first terminal and a second terminal can transmit and receive information, the first terminal and a third terminal can transmit and receive information, but the second terminal and the third terminal cannot transmit and receive information, at this time, after the first terminal sends a call request to the second terminal, the second terminal can receive the call request, then the second terminal replies the call request, normal communication is performed between the first terminal and the second terminal, in the process, for the third terminal, it cannot receive a confirmation message of the call request replied by the second terminal, so it can forward the call request of the first terminal to the second terminal, but since the information cannot be transmitted between the second terminal and the third terminal, the second terminal cannot receive and transmit the call request forwarded by the third terminal, and the third terminal cannot participate in the communication between the first terminal and the second terminal, the third terminal is also simply a normal conventional terminal.
Thirdly, as shown in fig. 7, information may be received and transmitted between the first terminal and the third terminal, information may not be received and transmitted between the first terminal and the second terminal, and information may not be received and transmitted between the second terminal and the third terminal, at this time, after the first terminal sends a call request to the second terminal, the second terminal may not receive the call request, and the third terminal may receive the call request, and then the third terminal determines that the second terminal does not reply the call request, and forwards the call request to the second terminal, but since information may not be received and transmitted between the second terminal and the third terminal, the second terminal still may not receive the call request, and then the third terminal still may not monitor that the second terminal replies the confirmation message, then the call service fails, and the third terminal fails to play a relay role.
Referring to fig. 8, fig. 8 is a schematic structural diagram of an embodiment of the terminal of the present application. The terminal 200 includes a processor 210, a memory 220, and a communication circuit 230, wherein the processor 210 is coupled to the memory 220 and the communication circuit 230, respectively, and the processor 210 implements the steps of the call processing method by executing the program data in the memory 220, wherein the detailed call processing method can refer to the foregoing embodiments and is not described herein again.
In an application scenario, the terminal 200 is an intercom, and in other application scenarios, the terminal 200 may also be other terminals such as a mobile phone, which is not limited herein.
Referring to fig. 9, fig. 9 is a schematic structural diagram of an embodiment of a device with a storage function according to the present application. The device 300 with storage function stores program data 310, and the program data 310 can be executed by a processor to implement the steps in the call processing method, wherein the detailed call processing method can refer to the above embodiments, and is not described herein again.
The device 300 with a storage function may be a device capable of storing the program data 310, such as a usb disk, a removable hard disk, a Read-Only Memory (ROM), a Random Access Memory (RAM), a magnetic disk, or an optical disk, or may be a server storing the program data 310, and the server may transmit the stored program data 310 to another device for operation, or may operate the stored program data 310 by itself.
In summary, on one hand, the call processing method in the application starts a common-frequency relay mode through a third terminal to play a relay role between a first terminal and a second terminal when information cannot be received and sent between the first terminal and the second terminal, thereby indirectly realizing communication between the first terminal and the second terminal, improving the success rate of a call service and prolonging the communication distance of the call service; and on the other hand, after the third terminal forwards the last frame of voice frame in the calling voice or the callback voice, the same-frequency transfer mode is closed, and then the third terminal does not transfer any more, but communicates like a conventional terminal, so that the working mode of the third terminal is flexibly changed.
The above description is only for the purpose of illustrating embodiments of the present application and is not intended to limit the scope of the present application, and all modifications of equivalent structures and equivalent processes, which are made by the contents of the specification and the drawings of the present application or are directly or indirectly applied to other related technical fields, are also included in the scope of the present application.
