In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

FIG. 2 is a schematic flowchart of a method for implementing real-time communication based on the World Wide Web provided by an embodiment of the present invention. As shown in FIG. 2 , the method for implementing real-time communication based on the World Wide Web in this embodiment may include:

201. The proxy device detects a session request message of a WWW-based real-time communication initiated by a terminal, where the session request message includes a bandwidth requirement.

Wherein, the session request message of the WWW-based real-time communication initiated by the terminal is a session request message initiated by the terminal to another terminal through the Web server.

For example, the session request message is a request message specified in the Session Description Protocol (English: Session Description Protocol, SDP for short), such as an offer message.

The terminal sends the session request message to request to establish a streaming media service with another terminal. The session request message includes a bandwidth requirement, wherein the bandwidth requirement included in the session request message is the bandwidth requested by the terminal for the streaming media service to be established. Usually, the session request message may also include service flow information such as service type, service port, and terminal IP address.

Wherein, the agent device is a real-time communication (English: Web Real-timecommunication, WebRTC for short) agent based on the World Wide Web. The WebRTC agent can be implemented by using a main board installed with WebRTC software. For example, the mainboard on which the WebRTC software is installed may be set in a wireless local area network (English: wireless local area network, WLAN for short) controller. The WLAN controller is usually used to manage and control a wireless access point (English: accesspoint, AP for short) device, and provide service configuration for the wireless access point device. The WLAN controller may be an access controller (English: Access Controller, AC for short) complying with Request for Comments (English: Request for Comments, RFC for short) 5415.

In one embodiment of the present invention, after the terminal connects to the network through a wireless access point device, the terminal creates streaming media session information on the terminal through a browser, such as allocating media session ports, audio and video encoding formats, etc. After that, the terminal Send a session request message to another terminal through the web server. The proxy device detects a session request message initiated by the terminal to another terminal through the web server, obtains the service flow information included in the session request message, and further obtains the bandwidth requirement included in the service flow information.

202. The proxy device determines whether the bandwidth requirement included in the session request message is greater than the bandwidth requirement included in the user subscription configuration information of the terminal, if the proxy device determines that the bandwidth requirement included in the session request message is less than or equal to the terminal Step 203 is executed if the proxy device determines that the bandwidth requirement included in the session request message is greater than the bandwidth requirement included in the user subscription configuration information of the terminal, then step 204 is executed.

Wherein, the user subscription configuration information is the user subscription configuration information configured for the terminal by the network operator when the terminal signs a contract with the network operator. For example, after the terminal successfully registers with the network operator on the network, the proxy device may, for example, obtain the authentication, authorization and accounting (English: Authentication Authorization Accounting, AAA) server of the network operator or the home subscriber server (English: Home Subscriber Server, The user subscription configuration information corresponding to the terminal is obtained and stored in HSS for short, where the user subscription configuration information includes the bandwidth requirement. Usually, the bandwidth requirement included in the user subscription configuration information refers to the maximum bandwidth that can be authorized to the terminal user. .

For example, if the bandwidth requirement included in the user subscription configuration information is 512 kilobits per second (English: kilobit per second, kbps for short), assume that the bandwidth requirement included in the service flow information initiated by the terminal is 1 million bits per second (English: megabit per second, Mbps for short), it can be determined that the bandwidth requirement included in the service flow information is greater than the bandwidth requirement included in the user subscription configuration information of the terminal. If the bandwidth requirement in the user subscription configuration information is 1 Mbps and the bandwidth requirement in the service flow information is 512 kbps, it can be determined that the bandwidth requirement included in the service flow information is smaller than the bandwidth requirement included in the user subscription configuration information of the terminal.

203. The proxy device sends the session request message to another terminal through the Web server.

If the proxy device determines that the bandwidth requirement included in the session request message initiated by the terminal is less than or equal to the bandwidth requirement included in the user subscription configuration information of the terminal, the proxy device sends the session request message to another terminal through the WEB server;

Optionally, the proxy device creates a temporary session state information table on the proxy device, and saves the bandwidth requirement included in the session request message into the temporary session state information table. Usually, in practical applications, in addition to the session request message In addition to saving the included bandwidth requirements in the temporary session state information table, the proxy device can also save other service flow information included in the session request message, such as service type, service port and terminal IP address, into the temporary session state information table middle.

204. The proxy device modifies the bandwidth requirement included in the session request message so that the bandwidth requirement included in the session request message is less than or equal to the bandwidth requirement included in the user subscription configuration information, and transmits the modified session request message through the Web The server sends to another terminal.

When it is determined that the bandwidth requirement included in the session request message initiated by the terminal is greater than the bandwidth requirement included in the user subscription configuration information of the terminal, the proxy device may modify the bandwidth requirement included in the session request message so that the session request message The bandwidth requirement included in is less than or equal to the bandwidth requirement included in the user subscription configuration information.

Optionally, the proxy device creates a temporary session state information table on the proxy device according to the modified session request message, and saves the bandwidth requirement in the modified session request message into the temporary session state information table, Usually, in practical applications, in addition to saving the bandwidth requirements in the modified session request message into the temporary session state information table, the proxy device can also store other service flow information included in the modified session request message, such as The service type, service port and IP address of the terminal are stored in the temporary session state information table.

205. The agent device detects a reply message of the real-time communication based on the World Wide Web that is responded by another terminal.

Wherein, the response message of the WWW-based real-time communication initiated by the other terminal is a pre-response or response message sent by the other terminal to the terminal through the Web server.

For example, the reply message is a kind of reply message stipulated in the session description protocol, such as a Pre-answer or answer message.

The response message includes the bandwidth requirement responded by the other terminal, and further, the response message also includes other service flow information responded by the other terminal, such as the IP address of the other port, the service type answered by the other terminal, the service port and other information.

In one embodiment of the present invention, after the proxy device sends the session request message or the modified session request message to another terminal, the other terminal creates streaming media session information on the other terminal through a browser, such as assigning a media session For another example, according to the service flow information in the received session request message, according to the service type included in the service flow information, select a voice and video coding format that supports the service type, if there are multiple Voice and video coding format, according to the priority of the preset voice and video coding format information, give priority to using the voice and video coding format with the highest priority, or choose a voice and video coding format among multiple supported voice and video coding formats. Afterwards, another terminal replies a pre-response or response message to the terminal through the web server.

In the implementation of the embodiment of the present invention using a proxy device to create a temporary session state information table, the proxy device detects a pre-response or response message sent by another terminal to the terminal through a Web server; the pre-response or response message includes another terminal response The bandwidth requirements and other service flow information; usually, the bandwidth requirements of the other terminal response will not exceed the bandwidth requirements contained in the session request message sent by the proxy device to the other terminal.

Assuming that the bandwidth requirement included in the pre-reply or reply message is inconsistent with the bandwidth requirement included in the temporary session state information table, the proxy device updates the The bandwidth requirement in the temporary session state information table, for example, assume that the bandwidth requirement included in the session request message initiated by the terminal is 1 Mbps, and assume that the proxy device detects that the bandwidth requirement included in the session request message initiated by the terminal does not exceed the user subscription of the terminal The bandwidth requirements included in the configuration information, if the maximum bandwidth requirement of another terminal is 512Kbps, when the bandwidth requirement in the pre-reply or response message sent by another terminal to the terminal is 512kbps, the proxy device The included bandwidth requirement updates the bandwidth requirement in the temporary session state information table created on the proxy device, that is, the proxy device updates the bandwidth requirement in the temporary session state information table created on the proxy device to 512Kbps.

In practical applications, if the session request message initiated by the terminal includes multiple service types, and the other terminal only responds to part of the service types, the proxy device updates the The business type in the created temporary session state information table, so as to release the resource space of the proxy device in time.

206. The proxy device sends the response message to the terminal.

After receiving the response message, the terminal updates the streaming media session information on the terminal, such as saving the IP address of the other terminal, the service port of the other terminal, the service flow information answered by the other terminal, the audio and video codec format, and the like. The terminal uses the modified streaming media session information to communicate according to the updated streaming media session information through the browser.

Optionally, besides the bandwidth requirement, the above session request message or response message also includes the IP address of the terminal, the IP address of another port, service type, service port and so on. Optionally, the proxy device can further obtain the service type in the session request message or the response message, configure the service quality level information corresponding to the service type, and then send the service quality level information corresponding to the service type to the terminal The wireless access point device connected, so that the wireless access point device sets the priority corresponding to the quality of service level information according to the service quality level information, so that the wireless access point device detects the service from the terminal After the flow, according to the service type included in the service flow information, determine the service quality (English: quality of service, referred to as QoS) level corresponding to the service type, and then mark the corresponding priority of the service flow, so that it can be realized according to the service Flow priority scheduling, for example, high-priority service packets are transmitted first, and low-priority service packets are transmitted later, ensuring the quality of service (QoS) of different service flows.

In the embodiment of the present invention, the proxy device monitors the session request message sent by the terminal to another terminal, and determines the session request message included in the session request message according to the bandwidth requirement included in the session request message and the bandwidth requirement included in the user subscription configuration information of the terminal. whether the bandwidth requirement included in the user subscription configuration information of the terminal is greater than the bandwidth requirement included in the terminal’s user subscription configuration information; if so, modify the bandwidth requirement included in the session request message so that the bandwidth requirement included in the session request message is smaller than the terminal’s user subscription configuration The bandwidth requirements included in the information; thus, it is possible to dynamically adjust the bandwidth requirements in the service flow information initiated by the terminal according to the bandwidth requirements included in the user subscription configuration information of the terminal, so that the real-time communication service based on the World Wide Web between the terminal and another terminal It will not be affected, and the continuity of the streaming media session between the terminal and another terminal is guaranteed.

502. The WebRTC proxy sends the session request message or the modified session request message to the terminal.

503. The WebRTC proxy detects the pre-response message returned by the terminal.

Specifically, after receiving the session request message or the modified session request message, the terminal creates streaming media session information on the terminal through the browser, for example, assigning a session port; for example, according to the session request message or the modified session request The business flow information in the message obtains media information such as voice and video supported by another terminal, and selects the media information used in this session. Optionally, if the terminal supports multiple voice and video encoding formats, select a voice according to user instructions Video encoding format. Then, send a pre-response message to another terminal through the web server.

After the WebRTC proxy detects the pre-response message returned by the terminal, if the bandwidth requirement in the pre-response message returned by the terminal is inconsistent with the bandwidth requirement in the temporary session state information table on the WebRTC proxy, the WebRTC proxy updates according to the bandwidth requirement in the pre-response message Bandwidth requirements in the temporary session state information table on the WebRTC proxy.

506. The WebRTC proxy detects the response message sent by the terminal to another terminal through the Web server.

Assuming that the terminal accepts the session request according to the user instruction, the terminal can be triggered to send a response message to another terminal through the Web server.

After the WebRTC agent detects the response message returned by the terminal, if the bandwidth requirement in the response message returned by the terminal is inconsistent with the bandwidth requirement in the temporary session state information table on the WebRTC agent, the WebRTC agent updates the WebRTC agent according to the bandwidth requirement in the response message Bandwidth requirements in the temporary session state information table on the proxy. Usually, the WebRTC agent can also save other service flow information in the response message, such as the service type, service port and terminal IP address of the terminal response, into the temporary session state information table.

507. The WebRTC proxy sends the response message to another terminal.

508. The other terminal updates the streaming media session information on the other terminal according to the response message.

For example, save the IP address and service port of the terminal, as well as the audio or video codec formats supported by the terminal. For another example, suppose the terminal only responds to part of the service flow information, and another terminal deletes other parts according to the part of the service flow information answered by the terminal business flow information.
