Detailed ways

The following will clearly describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, but not all of them. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments in this application belong to the protection scope of this application.

The terms "first", "second" and the like in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific sequence or sequence. It should be understood that the terms so used are interchangeable under appropriate circumstances such that the embodiments of the application can be practiced in sequences other than those illustrated or described herein, and that references to "first," "second," etc. distinguish Objects are generally of one type, and the number of objects is not limited. For example, there may be one or more first objects. In addition, "and/or" in the specification and claims means at least one of the connected objects, and the character "/" generally means that the related objects are an "or" relationship.

The technical terms that may be involved in this application are firstly explained below:

RTP (Realtime Transport Protocol, Real-time Transport Protocol): The RTP standard defines two sub-protocols, RTP and RTCP (Realtime Transport Control Protocol, Real-time Transport Control Protocol), which are used to transmit real-time audio, video, etc. in unicast or multicast networks. The data flow mainly transmits the protocol message through a network address and a pair of ports. One is for media data flow and the other is for control data flow.

SIP (Session Initiation Protocol, Session Initiation Protocol): It is mainly used for signaling interaction in a streaming media session, and controls the establishment, call, update, and destruction of the entire session.

SDP (Session Description Protocol, Session Description Protocol): It is mainly used to negotiate the relevant configuration parameter information of the media stream between terminals, and is often used as the message body of the signaling protocol to be conveyed to the opposite end along with the signaling.

ACK (Acknowledge character, confirmation character): In data communication, a transmission type control character sent by the data receiving end to the data sending end. Indicates that the incoming data has been confirmed to be received without error.

At present, audio and video calls between two terminals need to be processed and forwarded by the streaming media server, and the streaming media service system uses SDP to negotiate audio and video parameter information. Therefore, a total of four ports are required. Among them, audio occupies two ports, respectively transmits audio stream (that is, audio RTP) and corresponding control packet (that is, audio RTCP), and video also occupies two ports, respectively transmits video stream (that is, video RTP) and corresponding control packet ( Also known as video RTCP).

As shown in FIG. 1 , when a call is made between two terminals, the terminal 11 and the streaming media server 12 need to establish an RTP session, and the terminal 11 will also determine a pair of destination transmission addresses. The destination transmission address consists of a network address and four ports, two of which are used to transmit audio RTP data packets and audio RTCP data packets, and two are used to transmit video RTP data packets and video RTCP data packets.

That is to say, when a call is made between any two terminals, a special port is required to be provided by the streaming media server, so as to realize data exchange between any two terminals. For example, one call needs to occupy four ports in the streaming media server, two calls need to occupy eight ports in the streaming media server, and so on, as many pairs of terminals are used for calls, the streaming media server needs to provide as many ports as possible. This leads to the occupation of a large number of public network port resources, and due to the limited server port resources, the mode of occupying some dedicated ports for each call greatly restricts the maximum number of terminal connections that the streaming media server can support.

In order to solve the above technical problems, the present application provides a data interaction method, device, device and storage medium. Wherein, the data interaction method provided by the present application can be applied to the architecture shown in FIG. 2 , which will be described in detail in conjunction with FIG. 2 .

FIG. 2 is a schematic diagram of an architecture adapted to the data interaction method provided by the embodiment of the present application.

As shown in FIG. 2 , the architecture diagram may include a first terminal 21 , a second terminal 22 , a signaling server 23 , a streaming media server 24 and a media forwarding server 25 . Wherein, the first terminal 21 and the second terminal 22 can be any terminal devices such as mobile phones and computers. In this framework, in addition to the two terminals of the first terminal 21 and the second terminal 22, other multiple terminals can also be included. (not shown in FIG. 2 ), it is not limited here. In addition, the signaling server 23 can be a server for receiving and forwarding SIP signaling in the streaming media service system, and the streaming media server 24 can be a server for controlling terminal calls and processing call data in the streaming media service system. 25 is a server configured in the embodiment of the present application for data forwarding between any two terminals.

Exemplarily, before the first terminal 21 calls the second terminal 22, or the second terminal 22 calls the first terminal 21, the first terminal 21 needs to send the registration information of the first terminal 21 to the signaling server 23 through SIP signaling , the signaling server 23 forwards the received registration information to the streaming media server 24, and the streaming media server 24 processes the registration information of the first terminal 21 and registers the first terminal 21 to go online. Similarly, the second terminal 22 also needs to register by sending SIP signaling to the signaling server 23 .

Based on the above architecture, the data interaction method provided by the embodiment of the present application will be described in detail below through specific embodiments and application scenarios with reference to the accompanying drawings.

It should be noted that, the data interaction method provided in the embodiment of the present application may be executed by a data interaction device. In the embodiment of the present application, the data interaction method performed by the data interaction device is taken as an example to illustrate the data interaction method provided in the embodiment of the present application.

Fig. 3 is a flowchart of a data interaction method provided by an embodiment of the present application. This data interaction method can be applied to a server, such as the media forwarding server 25 in FIG. 2 above.

As shown in FIG. 3, the data interaction method may include steps: S310-S340, which will be described in detail below.

S310. Receive the first information sent by the first terminal and the second information sent by the second terminal, where the first information includes the first terminal identifier corresponding to the first terminal, the first destination terminal identifier, and the first terminal identifier corresponding to the first port. Port information, where the second information includes a second terminal identifier corresponding to the second terminal, a second destination terminal identifier, and port information corresponding to the second port.

In the embodiment of the present application, before the first terminal and the second terminal formally perform data interaction, the media forwarding server may first receive the first information sent by the first terminal and the second information sent by the second terminal. Wherein, the first information and the second information may be sent to the media forwarding server in the form of an RTP extended message.

Here, the first information may include the first terminal identifier corresponding to the first terminal, the first destination terminal identifier, and port information corresponding to the first port, and the second information may include the second terminal identifier corresponding to the second terminal, the second destination terminal Port information corresponding to the second port is identified. Wherein, the first terminal identifier may be an identifier capable of uniquely marking the first terminal. The first destination terminal identifier may be a unique identifier of the destination terminal that the first terminal needs to talk to. Similarly, the second terminal identifier may be an identifier capable of uniquely marking the second terminal. The second destination terminal identifier may be a unique identifier of the destination terminal that the second terminal needs to talk to. Wherein, the terminal identifier may be, for example, a mobile phone number, a MAC (Media Access Control, Media Access Control) address, and the like.

In addition, the first port is a port configured for data interaction in the first terminal, and the second port is a port configured for data interaction in the second terminal. The port information may be, for example, a port number or the like.

In some implementations, the first port may include a first audio port and a first video port, and the second port may include a second audio port and a second video port. Wherein, the first audio port and the second audio port may be, for example, audio RTP ports, for sending and receiving audio RTP/RTCP data. The first video port and the second video port may be, for example, video RTP ports for sending and receiving video RTP/RTCP data.

Of course, when only audio or video calls are made, the first port and the second port may also include only one type of port, which is not limited here.

Exemplarily, as shown in FIG. 2, before the first terminal 21 and the second terminal 22 send audio and video data to each other, the first terminal 21 first transmits its own terminal ID, destination terminal ID, its own audio RTP port information, video RTP The port information and the like are sent to the media forwarding server 25 through the RTP extended message. The media forwarding server 25 parses and registers the RTP extended message sent by the first terminal 21 . The same is true for the second terminal 22 , and the media forwarding service 25 also parses and registers after receiving the RTP extension message sent by the second terminal 22 .

S320. When the first destination terminal identifier matches the second terminal identifier, and the second destination terminal identifier matches the first terminal identifier, based on the port information corresponding to the first port and the port information corresponding to the second port, An association relationship between the first port and the second port is established.

In the embodiment of the present application, after receiving the information sent by the first terminal and the second terminal, the media forwarding server may match the own terminal identifier and the destination terminal identifier included in the information of both parties.

Specifically, the first destination terminal identifier sent by the first terminal is matched with the second terminal identifier sent by the second terminal to determine whether the terminal that needs to perform data transmission with the first terminal is the second terminal, and the second The second destination terminal identifier sent by the terminal is matched with the first terminal identifier sent by the first terminal to determine whether the terminal that needs to perform data transmission with the second terminal is the first terminal.

Exemplarily, as shown in FIG. 2 , after the media forwarding server 25 parses and registers the RTP extended messages sent by the first terminal 21 and the second terminal 22 respectively, it can transfer its own terminal identification, The target terminal identifier is cross-matched to obtain a matching result.

In this embodiment of the present application, matching may be a matching result obtained when terminal identities are the same, and non-matching may be a matching result obtained when terminal identities are different.

In addition, the way to establish the association relationship between the first port and the second port may be to store the port information of the first port in association with the port information corresponding to the second port, and when one of the port information is queried, it can be obtained Another port information saved in association.

Exemplarily, as shown in FIG. 2, if the destination terminal identifier of the first terminal 21 is the same as the own terminal identifier of the second terminal 22, and the destination terminal identifier of the second terminal 22 is the same as the own terminal identifier of the first terminal 21, It means that the data of the first terminal 21 will be sent to the second terminal 22 , and the data of the second terminal 22 will be sent to the first terminal 21 . In this way, the media forwarding server 25 can correspond the port information of the first port and the second port, indicating that subsequent data from the first terminal 21 will be sent to the second port of the second terminal 22, and data from the second terminal 22 will be sent to the second port of the second terminal 22. All will be sent to the first port of the first terminal 21.

In addition, in some implementation manners, in the case where the first port includes a first audio port and a first video port, and the second port includes a second audio port and a second video port, the above S320 may specifically include:

Establishing an association relationship between the first audio port and the second audio port based on the port information of the first audio port and the port information of the second audio port;

Based on the port information of the first video port and the port information of the second video port, an association relationship between the first video port and the second video port is established.

Exemplarily, the media forwarding server may associate and store the port information of the first audio port and the port information of the second audio port, so as to establish a connection between the first audio port of the first terminal and the second audio port of the second terminal. In addition, the port information of the first video port and the port information of the second video port can be associated and stored to establish a relationship between the first video port of the first terminal and the second video port of the second terminal. relationship.

In this way, by establishing an association between two audio ports and two video ports, it can be ensured that the audio and video RTP/RTCP data of the first terminal can be correctly forwarded to the second terminal respectively, and that the audio and video data of the second terminal can be correctly forwarded to the second terminal. The RTP/RTCP data can be correctly forwarded to the first terminal respectively, thereby improving the reliability of data transmission.

In addition, after the audio-video port information of the first terminal is in one-to-one correspondence with the audio-video port information of the second terminal, the port association relationship can be recorded and maintained in the media forwarding server as the basis for data forwarding during subsequent data interactions.

S330. Perform data interaction between the first terminal and the second terminal according to the association relationship.

Here, the first terminal and the second terminal can send data to each other.

Exemplarily, when the first terminal sends data to the second terminal, the media forwarding server may forward the data sent by the first terminal to the second port according to the association relationship between the first port and the second port; When the terminal sends data to the first terminal, the media forwarding server can forward the data sent by the second terminal to the first port according to the association relationship between the first port and the second port, so as to realize the connection between the first terminal and the second terminal. data interaction between them. In this way, the media forwarding server only needs to provide one external port for receiving the data sent by the first terminal and the second terminal, and the data forwarding between different ports can be realized inside the media forwarding server.

Thus, by setting the data forwarding service, receiving the first information sent by the first terminal and the second information sent by the second terminal, the first destination terminal identifier in the first information and the second terminal identifier in the second information match, and the second destination terminal identifier in the second information matches the first terminal identifier in the first information, between the first port provided by the first terminal and the second port provided by the second terminal An association relationship is established, and data forwarding is performed using the association relationship, so as to realize data interaction between the first terminal and the second terminal. In this way, the server no longer needs to provide a dedicated data transmission port for each pair of terminals, but only needs to provide a port on the public network, through which the data that the terminal needs to transmit is received, and the data is forwarded based on the association relationship between the terminal ports. It can realize data transmission between any two terminals, realize the multiplexing of public network ports, save the port resources of the public network, and increase the maximum number of terminal connections that the server can support.

Based on this, in some implementation manners, the above S330 may specifically include:

receiving first data sent by the first terminal from the first port;

determining a second port associated with the first port according to the association relationship;

Forwarding the first data to the second port, so as to send the first data to the second terminal;

and / or,

receiving second data sent by the second terminal from the second port;

determining the first port associated with the second port according to the association relationship;

Forwarding the second data to the first port, so as to send the second data to the first terminal.

Here, a target port may be set in the media forwarding server, and the target port may be a port set in the public network by the streaming media service system, and is used for receiving and sending data sent by each terminal. Wherein, the data may include at least one of audio data and video data. The audio data may include at least one of audio RTP data and audio RTCP data, and the video data may include at least one of video RTP data and video RTCP data.

Exemplarily, as shown in FIG. 2, after the first terminal 21 sends the RTP extended message and receives the ACK confirmation message sent by the media forwarding server 25, it starts to provide the media forwarding server 25 with a The media port normally sends audio and video RTP/RTCP data to send the data to the media forwarding server 25 . At this moment, the forwarding direction of the audio and video data of the first terminal 21 by the media forwarding server 25 has been made clear through step S320, and then data forwarding is carried out according to the associated port information registered and saved in the server, and finally the audio and video RTP/RTCP data of the first terminal 21 is forwarded. forwarded to the second terminal 22. The same is true when the second terminal 22 sends the audio/video RTP/RTCP data to the first terminal 21 , which will not be repeated here. So far, the first terminal 21 and the second terminal 22 start two-way audio and video RTP/RTCP data interaction.

In this way, each terminal only needs to know a target port provided by the media forwarding server, and can implement audio and video calls between any two terminals, realizing port multiplexing.

Based on this, in some embodiments, if the second port includes the second audio port and the second video port, if the first data includes the first audio data and the first video data, then the above-mentioned first data is forwarded to The step of the second port may specifically include:

Forwarding the first audio data to the second audio port;

Forwarding the first video data to the second video port.

Here, the first audio data and the first video data may be respectively forwarded to different types of second ports. Specifically, the first audio data may be forwarded to the second audio port, and the first video data may be forwarded to the second video port.

Exemplarily, the media forwarding server may forward the audio RTP/RTCP data sent by the first terminal to the audio port of the second terminal, and forward the video RTP/RTCP data sent by the first terminal to the video port of the second terminal.

In this way, the audio data and video data sent by the first terminal are respectively forwarded to different ports of the second terminal, which can improve the reliability of data transmission.

Similarly, in some implementations, when the first port includes the first audio port and the first video port, if the first data includes the first audio data and the first video data, then the above-mentioned second data is forwarded to The steps of the first port may specifically include:

forwarding the second audio data to the first audio port;

Forwarding the second video data to the first video port.

Here, the second audio data and the second video data may be respectively forwarded to different types of first ports. Specifically, the second audio data may be forwarded to the first audio port, and the second video data may be forwarded to the first video port.

Exemplarily, the media forwarding server may forward the audio RTP/RTCP data sent by the second terminal to the audio port of the first terminal, and forward the video RTP/RTCP data sent by the second terminal to the video port of the first terminal.

In this way, the audio data and video data sent by the second terminal are respectively forwarded to different ports of the first terminal, which can improve the reliability of data transmission.

Fig. 4 is a flowchart of a data interaction method provided by an embodiment of the present application. This data interaction method can be applied to a terminal, such as the first terminal 21 or the second terminal 22 in FIG. 2 above.

As shown in Figure 4, the data interaction method may include:

S410. Acquire a first terminal identifier corresponding to the first terminal, a first destination terminal identifier, and port information corresponding to the first port;

S420. Send to the server first information including the first terminal identifier, the first destination terminal identifier, and port information corresponding to the first port, so that the server establishes the first port according to the first information and the second information sent by the second terminal an association relationship with the second port of the second terminal;

S430. Based on the association relationship, perform data interaction with the second terminal through the server.

For the relevant explanations above, reference may be made to relevant parts of the foregoing embodiments, and details are not repeated here.

Therefore, by sending the first information including the first terminal identifier, the first target terminal identifier, and the port information corresponding to the first port to the server, the server can make the first information sent by the first terminal and the first information sent by the second terminal The second information is to establish an association relationship between the first port of the first terminal and the second port of the second terminal, and then use the association relationship to perform data forwarding and realize data interaction between the first terminal and the second terminal. In this way, the server no longer needs to provide a dedicated data transmission port for each pair of terminals, but only needs to provide a port on the public network, and each terminal such as the first terminal can send or receive the data to be transmitted through this port, and based on the terminal port The association relationship between them realizes the data transmission between any two terminals, thereby realizing the multiplexing of public network ports, saving the port resources of the public network, and increasing the maximum number of terminal connections that the server can support.

In some implementations, before the above S420, the data interaction method provided in the embodiment of the present application may further include:

Acquire first terminal address information and first configuration parameters corresponding to the first terminal;

Sending call information for the second terminal to the server, so as to be forwarded to the second terminal through the server, wherein the call information includes the address information of the first terminal and the first configuration parameters, and the call information is used to instruct the second terminal to Establish a first data processing module, and instruct the second terminal to send response information to the first terminal through the server according to the address information of the first terminal, and the first data processing module is used to receive and process the data sent by the first terminal;

receiving response information sent by the server, where the response information includes second terminal address information and second configuration parameters corresponding to the second terminal;

A second data processing module is established according to the second configuration parameter, wherein the second data processing module is configured to receive and process data sent by the second terminal.

Here, the first terminal address information may include one or more candidate address information corresponding to the first terminal, and the first configuration parameter may be a parameter related to data processing. For example, when the data is audio and video data, the first configuration parameter may be It is an audio and video stream configuration parameter. In addition, the second terminal address information may include one or more candidate address information corresponding to the second terminal, and the second configuration parameter may be a parameter related to data processing.

In addition, the call information may be, for example, SIP call signaling, and correspondingly, the response information may be, for example, a SIP call response message.

Exemplarily, as shown in FIG. 2, the first terminal 21 organizes and collects its own candidate address information, audio and video stream configuration parameters and combines them into SDP information, which is sent to the signaling server 23 as the message body of the SIP call signaling, and the signaling The server 23 forwards the received SIP call signaling to the streaming media server 24, and the streaming media server 24 analyzes the SIP calling signaling, finds the second terminal 22 of the call, and forwards the SIP calling signaling through the signaling server 23 to the second terminal 22 .

The second terminal 22 analyzes the received SIP call signaling, finds the source of the message, that is, the first terminal 21, and then also organizes its own candidate address information, audio and video stream configuration parameters and combines them into SDP information as a SIP call The message body of the response message is sent to the signaling server 23; the signaling server 23 forwards the SIP call response message to the streaming server 24, and the streaming server 24 parses the SIP call response message after receiving the SIP call response message , find the destination terminal for sending the response message, that is, the first terminal 21, and then forward the SIP call response message to the first terminal 21 through the signaling server 23.

At the same time, the second terminal 22 obtains the audio and video media parameters of the first terminal 21 by analyzing the received SIP call signaling at the same time, and establishes corresponding tasks such as data receiving channels and audio and video codecs by analyzing the media parameters, and prepares The data sent by the first terminal 21 is received.

After receiving the SIP call response message from the second terminal 22, the first terminal 21 confirms that the two parties have negotiated related data configuration parameters. Then the first terminal 21 starts to analyze the SIP call response message, obtains the audio and video media parameters of the second terminal 22, and by analyzing the media parameters, establishes corresponding data receiving channels, audio and video codecs, etc., and is ready to receive the second terminal 22. coming data.

In this way, by transferring terminal address information and configuration parameters between two terminals that need to talk, data processing modules can be respectively established on the two terminals to process subsequent received data.

In addition, in some implementation manners, the above S430 may specifically include:

When the server successfully establishes the association relationship, the first data is sent from the first port to the server, so that the server forwards the first data to the second port of the second terminal according to the association relationship.

Here, after the first terminal receives the ACK confirmation message sent by the server, it can be determined that the server has successfully established the association relationship between the first port and the second port, and at this time, data interaction with the second terminal can begin.

In this way, after it is determined that the server successfully establishes the association relationship, the first port of the first terminal sends the first data to the server, so that the server can process the first data according to the association relationship between the first port and the second port. Forwarding, so that there is no need for the server to set a special port for each call, the data transmission from the first terminal to the second terminal can be realized, and the multiplexing of public network ports can be realized.

In addition, when the second terminal sends data to the first terminal, the second terminal can send the second data to the server from the second port, so that the server forwards the second data to the first port of the first terminal according to the association relationship.
