Real-time voice, video data Transport Protocol (RTP), defined as a Transport Protocol for transmitting Real-time data such as audio, video, analog data, etc., is more emphasized in Real-time data transmission than the conventional Transport layer Protocol for highly reliable data transmission, which provides services including data sequence numbers, time stamps, transmission control, etc.
Real-time voice, video data Transport Control Protocol (RTCP), which generally works with RTP, where RTP is only responsible for the transmission of Real-time data and RTCP is responsible for out-of-band management of RTP's communication and sessions, such as flow Control, congestion Control, session source management, etc. The RTP is located in a transport layer, usually located above a User Datagram Protocol (UDP), and below an application program, real-time voice and video data are subjected to analog-to-digital conversion and compression coding, and then sent to the RTP to be encapsulated into an RTP data unit, and the RTP data unit is encapsulated into a UDP data packet, and then delivered to the IP to be encapsulated into an IP data packet. The RTP packets contain only RTP data and control is provided by another mating protocol RTCP. RTP selects an unused even UDP port number between port numbers 1025 to 65535, while RTCP in the same session uses the next odd UDP port number. During the RTP session, each participant periodically sends RTCP messages. The RTCP messages contain information about packet loss statistics and network congestion of the transmitted data, which can be used by the server to dynamically change the transmission rate. RTCP messages are also encapsulated into UDP datagrams for transmission.

The following describes in detail a data processing method provided in an embodiment of the present application with a specific example.
Fig. 2 is a flowchart of a data processing method according to an embodiment of the present application, and as shown in fig. 2, the method according to the embodiment of the present application includes:
s101, the first terminal device sends first data to a server.
The first data may be understood as a group transmission message that the first terminal desires to transmit to the second terminals.
Optionally, the first data may be audio data, video data, or general text data, and the like, and the type of the first data is not limited in this embodiment of the application, and is specifically determined according to actual needs.
S102, the server caches the first data in a cache queue.
Fig. 3 is an application scenario diagram provided in the embodiment of the present application. As shown in fig. 3, in order to prevent the second terminal from being in the sleep state, the server sends the first data to the second terminal device, so that the second terminal device cannot receive the first data in the period of time from the sleep state to the working state, and a buffer queue is set for the first data. When the server receives the first data sent by the first terminal equipment, the first data are not directly sent to each second terminal equipment, the received first data are firstly cached in the cache queue, and when the opportunity is mature, the first data are sent to the second terminal equipment, so that the problem that the first data cannot be completely received due to the fact that the second terminal equipment is in a dormant state can be avoided, and the reliability and the integrity of the first data transmission are improved.
S103, the server sends a first message to each second terminal device in the N second terminal devices.
The first message is used for indicating that the second terminal device is ready to receive the first data to be sent, and N is a positive integer greater than or equal to 1.
After caching the first data in the cache queue, the server sends a first message to each of the N second terminal devices. The first message is used for indicating that the second terminal equipment is ready to receive the first data to be sent.
Optionally, the first message may be a broadcast message.
In this step, the purpose of sending the first message to each second terminal device by the server is to switch the second terminal device currently in the dormant state to the working state, and when the second terminal device is in the working state, the server can receive the complete first data sent by the server.
And S104, the second terminal equipment sends a second message to the server according to the first message.
The second message is used for indicating that the second terminal device is ready to receive the first data, and the second message is sent when the second terminal device is in a working state.
And after receiving the first message sent by the server, each second terminal device sends a second message to the server, wherein the second message is used for indicating that the second terminal device is ready to receive the first data.
This step can be divided into the following two cases according to the state of the second terminal device when receiving the first message:
in case 1, if the second terminal device is in the working state before receiving the first message sent by the server, the second terminal device can immediately send the second message to the server to inform the server that the server is ready to receive the first data.
In case 2, if the second terminal device is in the dormant state before receiving the first message sent by the server, at this time, after receiving the first message, the second terminal device first switches from the dormant state to the working state, and in the working state, sends the second message to the server to inform the server that the server is ready to receive the first data.
In this way, different second terminal devices may send the second message to the server at different times, depending on the state of the second terminal device before receiving the first message and the network conditions of the second terminal device. For example, the time when the second terminal device in the working state sends the second message to the server before receiving the first message is prior to the time when the second terminal device in the dormant state sends the second message to the server before receiving the first message.
And S105, for each second terminal device, if the server detects a second message sent by the second terminal device, sending the first data in the cache queue to the second terminal device.
And after the server sends the first message to each second terminal device, monitoring a channel between each second terminal device and the server in real time. And if the second message sent by the second terminal device is detected on a channel between the second terminal device and the server, the server sends the first data in the cache queue to the second terminal device.
That is, in the embodiment of the present application, the server sends the first data to the second terminal device after detecting the second message sent by the second terminal device. That is to say, when the second terminal device is in the working state, the server sends the first data to the second terminal device, so that the problem that the first data is lost when the first data is sent to the second terminal device in the dormant state can be avoided, and the transmission reliability and integrity of the first data are further improved.
In the data processing method provided by the embodiment of the application, the first terminal device sends the first data to the server, the server caches the first data in the cache queue, and then the server sends a first message to each of the N second terminal devices, where the first message is used to indicate that the second terminal device is ready to receive the first data to be sent. After receiving the first message, the second terminal device in the dormant state is switched to the working state from the dormant state, and sends a second message to the server, wherein the second message is used for indicating that the second terminal device is ready to receive the first data, and the second message is sent when the second terminal device is in the working state; then, for each second terminal device, if a second message sent by the second terminal device is detected, the server sends the first data in the buffer queue to the second terminal device. Therefore, the problem that the first data are lost when the server sends the first data to the second terminal equipment in the dormant state can be effectively avoided, and the transmission reliability and integrity of the first data are improved.
Fig. 4 is a flowchart of a data processing method according to another embodiment of the present application, where based on the foregoing embodiment, as shown in fig. 4, the method according to the embodiment of the present application includes:
s200, the server configures the maximum sending time delay for each second terminal device.
The maximum sending time delay is the maximum waiting time from the server sending the first message to the second terminal device to the server sending the first data to the second terminal device.
In order to prevent the problem that the service waits endlessly for the second messages sent by the second terminal devices without sending the first data to the second terminal devices, the server sets a maximum sending delay for each second terminal device, wherein the maximum sending delay can be understood as the maximum waiting time from the sending of the first message by the server to the sending of the first data to the second terminal devices.
For example, the maximum transmission delay corresponding to the second terminal device 1 is 5s, so that the server determines whether the second message sent by the second terminal device 1 is received within 5s after the server sends the first message to the second terminal device 1.
S201, the first terminal device sends first data to a server.
S202, the server buffers the first data into a buffer queue.
S203, the server sends a first message to each second terminal device in the N second terminal devices.
The first message is used for indicating that the second terminal device is ready to receive the first data to be sent, and N is a positive integer greater than or equal to 1.
And S204, the second terminal equipment sends a second message to the server.
The second message is used for indicating that the second terminal device is ready to receive the first data, and the second message is sent when the second terminal device is in a working state.
The above-mentioned steps S201 to S204 are identical to the specific execution process of the above-mentioned steps S101 to S104, and refer to the description of the above-mentioned steps S101 to S104, which are not described herein again.
S205, if the server detects that the second message sent by the second terminal device is received within the maximum sending time delay corresponding to the second terminal device, the server sends the first data in the cache queue to the second terminal device.
Specifically, after the server sends the first message to the second terminal device, the server waits for the second message sent by the second terminal device, and if the server receives the second message sent by the second terminal device within the maximum sending delay corresponding to the second terminal device, the server sends the first data in the cache queue to the second terminal device.
For example, the maximum transmission delay corresponding to the second terminal device 1 is 5s, so that the server detects whether the second message sent by the second terminal device 1 is received within 5s after the server sends the first message to the second terminal device 1. And if the server detects that the second message sent by the second terminal equipment 1 is received in 5s after the first message is sent to the second terminal equipment 1, the first data in the cache queue is sent to the second terminal equipment.
In one possible implementation, the method further includes:
and S206, if the server detects that the second message sent by the second terminal equipment is not received within the maximum sending time delay corresponding to the second terminal equipment, the server sends the first data in the cache queue to the second terminal equipment.
In order to prevent the server from waiting for the second message sent by the second terminal device without limitation, when the server detects that the second message sent by the second terminal device is not received within the maximum sending delay corresponding to the second terminal device, and when the maximum sending delay corresponding to the second terminal device arrives, the first data in the cache queue is sent to the second terminal device.
In some embodiments, as shown in fig. 5, the embodiments of the present application further include: the server configures a buffer queue for each of the N second terminal devices.
At this time, the step of buffering the first data into the buffer queue by the server in S202 includes: and the server caches the first data in a cache queue of each second terminal device in the N second terminal devices.
In the above S205, the sending the first data in the buffer queue to the second terminal device includes: and the server sends the first data in the buffer queue of the second terminal device to the second terminal device.
Fig. 6 is a schematic diagram of a data transmission channel according to an embodiment of the present application. In some embodiments, as shown in fig. 6, there are RTP and RTCP channels between the first terminal device and the server, and RTP and RTCP channels between the server and the second terminal device.
Therefore, the first terminal device sends the first data to the server through the RTP channel between the first terminal device and the server, and the server sends the first data to the second terminal device through the RTP channel between the server and the second terminal device.
Continuing with fig. 6, the server sends the first message to the second terminal device through an RTCP channel between the server and the second terminal device, and the second terminal device sends the second message to the server through an RTCP channel between the second terminal device and the server.
