The technical scheme of the embodiment of the application is suitable for a group calling service system, and by adopting the technical scheme of the embodiment of the application, the group calling voice data is transferred by the group calling terminal equipment, so that the voice data transmission between the earphone and the base station can be realized.
For example, as shown in fig. 1, the group call service system includes a base station, a group call terminal device, and an earphone connected to the group call terminal device. The number of the above-mentioned earphones is multiple, each earphone and the group call terminal device are held by a service person in the service system, only one service person holds the group call terminal device in the service system, and other service persons hold the earphones.
The technical scheme of the embodiment of the present application is applied to the group call terminal equipment in the group call service system, and by executing the technical scheme of the embodiment of the present application, the group call terminal equipment in the group call service system forwards the voice data in the group call service, thereby realizing the group call voice data communication of the group call service system.
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.
Referring to fig. 2, a method for forwarding and processing voice data applied to a group call terminal device according to an embodiment of the present application includes:
s201, receiving group calling voice data issued by a base station;
specifically, the base station is used as an upper layer communication device in the group call service system shown in fig. 1, and is responsible for uplink and downlink transmission of voice data in the entire group call service. The base station is connected with the upper layer service management system and simultaneously connected with each terminal device in the group calling service system.
The group call voice data is the voice data from the upper layer received by the base station, and the destination terminal of the voice data is the group call terminal equipment, each earphone, etc. in the group call. And after receiving the group calling voice data sent by the upper layer of the group calling service system, the base station sends the group calling voice data to the group calling terminal equipment.
The group call terminal devices include, but are not limited to, terminal devices such as mobile phones and mobile stations that directly communicate with the base station in the group call service system.
S202, broadcasting and sending the group calling voice data to each earphone connected with the group calling terminal equipment.
Specifically, after receiving the group call voice data issued by the base station, the group call terminal device locally plays the group call voice data.
And simultaneously, the group calling terminal equipment also forwards the received group calling voice data to each earphone connected with the group calling terminal equipment.
The number of the earphones is usually multiple because the number of the service personnel in the group call service system is usually large; in special cases, the number of the earphones can be one.
The earphones are connected with the group calling terminal equipment in a wired connection or wireless connection mode. As a preferred connection mode, in order to ensure the flexibility of the group call service system and facilitate the activities of service personnel in the system, each of the above-mentioned earphones is connected with the group call terminal device in a wireless connection mode, for example, may be connected with the group call terminal device in a wireless connection mode such as bluetooth.
The earphones can be divided into earphones having both sound receiving and sound emitting functions and earphones having only sound emitting functions. In practical application, for the business personnel who need to receive the group call voice data of the system and send the voice data in the group call business system, an earphone with the functions of receiving and sounding at the same time should be equipped; for the service personnel who only need to receive the group call voice data of the system and do not have the requirement of sending the voice data in the group call service system, the earphone only having the sound production function can be equipped.
It can be understood that, through the forwarding processing of the group call voice data by the group call terminal device, the earphone in the group call service system does not need to be directly connected with the base station, and can realize the acquisition of the group call voice data only by being connected with the group call terminal device.
As can be seen from the above description, in the voice data forwarding processing method provided in the embodiment of the present application, the group call terminal device forwards the group call voice data issued by the base station to each earphone connected to the group call terminal device, so as to implement voice data transmission between the earphone and the base station. The technical scheme is applied to a group calling service system, a single service person holds group calling terminal equipment, and other service persons hold earphones connected with the group calling terminal equipment, so that all service persons in the group calling service system can receive group calling voice data issued by a base station.
As an exemplary implementation manner, referring to fig. 3, another embodiment of the present application further discloses that the voice data forwarding processing method further includes:
s303, sending voice data to the base station;
illustratively, when the group call terminal device is a mobile station, the user can send voice data to the base station by pressing the PTT button of the mobile station and speaking into the microphone of the mobile station.
Meanwhile, the group call terminal device further executes step S304 to send the voice data sent to the base station to each earphone.
Specifically, while sending the uplink voice data to the base station, the group call terminal device also sends the voice data to each earphone connected to the group call terminal device, so that each earphone plays the voice data sent by the group call terminal device in the uplink.
The above processing procedure realizes that when the group call terminal equipment sends voice data, the voice data can be broadcasted to each earphone in the group call service system, and each service personnel in the group call service system can acquire the uplink voice data in the group call service system.
Steps S301 and S302 in the method embodiment shown in fig. 3 correspond to steps S201 and S202 in the method embodiment shown in fig. 2, respectively, and for specific contents, please refer to the contents of the method embodiment shown in fig. 2, which is not described herein again.
As an exemplary implementation manner, referring to fig. 4, another embodiment of the present application further discloses that the voice data forwarding processing method further includes:
s403, receiving a voice sending request sent by any earphone connected with the group calling terminal equipment;
specifically, when the earphone in the group call service system needs to send voice data, the voice sending key is triggered to send voice sending request information to the group call terminal device.
For example, the voice sending key may be a function key of the headset, such as a volume adjustment key, a phone answering key, and the like. When the user triggers the voice sending key in a set triggering mode, the earphone sends a voice sending request to the group calling terminal equipment.
The above process is similar to the process of the user triggering the PTT button of the handset to send voice to the base station, except that the earphone sends the voice sending request to the group call terminal device, not directly to the base station.
After receiving the voice transmission request sent by the earphone, the group call terminal equipment executes step S404, and sends a request to the base station to establish an uplink data channel with the base station.
Specifically, the process of the group call terminal device requesting the base station to establish the uplink data channel between the group call terminal device and the base station is the same as the process of the user triggering the PTT key of the group call terminal device to establish the uplink data channel between the group call terminal device and the base station, and the embodiment of the present application is not described in detail.
Generally, when a group call terminal device sends an uplink data channel establishment request to a base station, the group call terminal device obtains a response from the base station and establishes an uplink data channel with the base station, and at this time, the group call terminal device may send uplink voice data to the base station.
And after the group calling terminal equipment establishes an uplink data channel with the base station, feeding back response information to an earphone sending a voice sending request.
At the moment, the earphone can collect the voice data of the user through the microphone and send the collected voice data to the group calling terminal equipment.
The group call terminal equipment executes step S405, receives the voice data sent by the earphone, and sends the received voice data to the base station through the uplink data channel.
Specifically, after receiving the voice data sent by the earphone, the group call terminal device sends the received voice data to the base station.
It can be appreciated that the above process achieves the purpose of the headset sending voice data to the base station.
According to the technical scheme of the embodiment of the application, the voice data communication between the earphone and the base station can be realized, and in the process, the earphone is not required to directly establish a data channel with the base station, and only the data channel is required to be established between a single group calling terminal device and the base station, so that the air interface resource can be saved to the maximum extent.
As a preferred implementation manner, in the embodiment of the present application, when the group call terminal device executes the step S405, it further executes the step S406 to play the received voice data, and broadcast and send the received voice data to other earphones connected to the group call terminal device.
Specifically, in a conventional group call service system, as long as any one terminal in the system sends uplink voice data, all terminals in the system can receive the voice data, so that all parties in a group call can receive the voice data in the system in real time.
When the group call service is realized, in order to enable each earphone holder in the group call service system to receive voice data sent by the other party, when the group call terminal equipment receives the voice data sent by any earphone in the group call service system, the voice data is broadcast and sent to all earphones in the system, and meanwhile, the group call terminal equipment also plays the voice data locally, so that the effect that each member in the system can receive the voice data when any earphone in the group call sends the voice data can be achieved, namely, the effect that each member in the system receives the voice data in the system in real time is achieved.
Steps S401 and S402 in the method embodiment shown in fig. 4 correspond to steps S101 and S102 in the method embodiment shown in fig. 1, respectively, and for specific contents, please refer to the contents of the method embodiment shown in fig. 1, which is not repeated herein.
In summary, it can be understood that, by applying the voice data forwarding processing method provided in the embodiment of the present application, in the entire group call service system, only by means of the data channel between a single group call terminal device and the base station, the communication between all terminals and the base station in the entire group call service system can be realized, and meanwhile, the voice data communication between each member in the entire group call service system can be realized. And the process only needs a single group calling terminal device and a plurality of earphones connected with the group calling terminal device, and the application of the scheme can realize the group calling service with the lowest cost and the least empty occupation.
