[0020] The message processing method applied to a distributed cluster system provided in the embodiment of the present application can be applied to Figure 1 In the application environment shown, the terminal 102 communicates with the server 104 through a network. The data storage system 106 can store data that the server 104 needs to process. The data storage system 106 can be integrated on the server 104, or placed on the cloud or other network servers.

[0021] The server 104 is a distributed cluster system composed of multiple physical servers. The system includes an upper domain, a lower domain, and a cache middleware. The upper domain communicates and interacts with at least one upper platform, the lower domain communicates and interacts with at least one lower device, and the cache middleware communicates and interacts with the upper domain and the lower domain. On the server 104, the SIP request message sent by the upper platform is obtained through the upper domain, and the SIP request message is sent to the lower domain; the SIP request message is forwarded to the corresponding lower device through the lower domain, and the lower device generates a first response message based on the SIP request message; the key information of the first response message is stored through the cache middleware; the key information corresponding to the SIP request message is queried in the cache middleware through the upper domain, and the key information is assembled to generate a second response message of the SIP request message.

[0023] In one of the embodiments, the lower-level domain is also used to obtain the second request header of the first response message; parse the second request header to extract the second target information of the first response message; obtain the first target information of the upper-level platform, replace the second target information of the second request header with the first target information, and send the replaced second request header to the cache middleware; the key information includes the replaced second request header.

IoT devices may be smart speakers, smart TVs, smart air conditioners, smart car devices, projection devices, etc. Portable wearable devices may be smart watches, smart bracelets, head-mounted devices, etc.

[0025] In an exemplary embodiment, Figure 2As shown, a message processing method applied to a distributed cluster system is provided. Figure 1 The server side in is taken as an example to illustrate, including the following steps 201 to 204.

[0026] Step 201: Obtain a SIP request message sent by the upper-level platform through the upper-level domain, and send the SIP request message to the lower-level domain.

[0027] Among them, the upper-level domain receives the SIP request message sent by the upper-level platform, uses the Jani-sip protocol stack to parse the SIP request message, obtains the request header of the SIP request message, modifies the device parameter information of the request header according to the lower-level device corresponding to the SIP request message, and uses the SipProvider interface of the Jani-sip protocol stack to send the modified SIP request message to the lower-level domain.

[0028] Step 202: forward the SIP request message to a corresponding lower-level device through the lower-level domain, and the lower-level device generates a first response message based on the SIP request message.

[0029] Specifically, the lower-level domain forwards the SIP request message to the corresponding lower-level device according to the replaced request header, and the lower-level device receives the SIP request message, parses and responds, and generates a first response message.

[0030] Step 203: storing key information of the first response message through the cache middleware.

[0031] Specifically, the key information includes at least one data information in the request header and request body of the first response message. According to the upper-level platform corresponding to the first response message, the lower-level device modifies the second target information in the request header or request body of the first response message, and caches the modified request header or request body of the first response message in the cache middleware.

[0032] Step 204: query the cache middleware for the key information corresponding to the SIP request message through the upper domain, assemble the key information, and generate a second response message to the SIP request message.

[0033] Specifically, the upper domain constructs a response query task according to the refresh mechanism, and the function of the response query task is to query the cache middleware for the request header of the lower-level device corresponding to the SIP request message. If the request header is found, the relevant data information is extracted and assembled to generate the second response message of the SIP request message.

[0034] In the above-mentioned message processing method applied to the distributed cluster system, the original sending mechanism of the SIP protocol stack is adjusted. By bypassing the SIP protocol stack's processing of requests, responses, transactions and dialog boxes, that is, bypassing the management of the SIP session state, the SIP message sending method without session state is realized, and the problem of cross-platform SIP service message interaction is solved.

[0035] In one embodiment, step 202 forwards the SIP request message to the corresponding lower-level device through the lower-level domain, and specifically includes the following contents: The method comprises the steps of: obtaining a first request header of the SIP request message through the lower-level domain; parsing the first request header to extract first target information of the SIP request message; obtaining second target information of the lower-level device, replacing the first target information with the second target information, and forwarding the replaced SIP request message to the corresponding lower-level device.

[0036] Among them, the first target information of the SIP request message includes the user information of the upper-level platform. If the lower-level domain needs to forward the SIP request message containing the first target information directly to the lower-level device, it involves the issue of cross-platform authority security. The traditional forwarding method is that the lower-level domain reassembles the original SIP request message sent by the upper-level platform, generates a new text protocol and sends it to the corresponding lower-level device, including a series of operations such as initiation, establishment, modification, and termination of the SIP session. The processing flow is complicated and affects the system service performance. Therefore, in this embodiment, by obtaining the second target information of the lower-level device, that is, the user information of the lower-level platform, the first target information is replaced with the second target information, and the replaced SIP request message is forwarded to the corresponding lower-level device, bypassing the management of the session life cycle to implement the SIP session-free message sending method, thereby improving the efficiency of the system message transmission response and simplifying the message processing process.

[0037] It should be noted that, in addition to the user information, the first target information of the SIP request message and the second target information of the first response message also include other information in the request header. For example, if the SIP request message or the first response message is an invite request, the first target information or the second target information also includes the from information, to information, contact information, and subject information in the request header. For another example, if the SIP request message or the first response message is a message request, the first target information or the second target information also includes the from information and to information in the request header.

[0038] In one embodiment, after the lower-level device generates a first response message based on the SIP request message in step 202, the method further includes the following contents: Obtain the second request header of the first response message through the lower-level domain; parse the second request header to extract the second target information of the first response message; obtain the first target information of the upper-level platform, replace the second target information of the second request header with the first target information, and send the replaced second request header to the cache middleware; the key information includes the replaced second request header.

[0039] More specifically, the replaced second request header corresponding to the SIP request message is queried in the cache middleware through the upper domain, and the replaced second request header is extracted and assembled to generate a second response message to the SIP request message.

[0040] Furthermore, the second response message is sent to the corresponding upper platform through the upper domain using the SipProvider interface of the Jani-sip protocol stack.

[0041] Among them, after the lower-level device generates the first response message based on the SIP request message, the lower-level domain parses the first response message to obtain the second request header of the first response message. Since the second request header is the data information required by the upper-level platform, the lower-level domain replaces the second target information representing the lower-level device in the second request header with the first target information representing the upper-level platform, and sends the replaced second request header to the cache middleware, waiting for the query of the upper-level domain, bypassing the management of the session life cycle to implement the SIP session-free message sending method, so that the SIP protocol stack is only responsible for encoding or parsing the incoming message, simplifying the SIP message processing mechanism.

[0042] In one embodiment, step 202 forwards the SIP request message to the corresponding lower-level device through the lower-level domain, and further includes the following contents: The method comprises the steps of: obtaining a first request body of the SIP request message through the lower-level domain; parsing the first request body to extract third target information of the SIP request message; obtaining fourth target information of the lower-level device, replacing the third target information with the fourth target information, and forwarding the replaced SIP request message to the corresponding lower-level device.

[0043] In one embodiment, after the lower-level device generates a first response message based on the SIP request message in step 202, the method further includes the following contents: When the key information is a request body, the second request body of the first response message is obtained through the lower-level domain; the second request body is parsed to extract the fourth target information of the first response message; the third target information of the upper-level platform is obtained, the fourth target information of the second request body is replaced with the third target information, and the replaced second request body is sent to the cache middleware; the key information includes the replaced second request body.

[0044] It should be noted that the third target information of the SIP request message and the fourth target information of the first response message are replacement information including the request body. If the SIP request message or the first response message is an invite request, the third target information and the fourth target information are o, c, and m field information in the request body; if the SIP request message or the first response message is a message request, the third target information and the fourth target information are DeviceID information in the request body.

[0045] In a preferred embodiment, a message processing method applied to a distributed cluster system is provided, which specifically includes the following steps: Step 1: The upper-level domain obtains the SIP request message sent by the upper-level platform, and uses the SipProvider interface to send the SIP request message to the lower-level domain.

[0046] Step 2: The lower-level domain obtains the first request header of the SIP request message; parses the first request header to extract the first target information of the SIP request message; obtains the second target information of the lower-level device, replaces the first target information with the second target information, and forwards the replaced SIP request message to the corresponding lower-level device.

[0047] Step 3: The lower-level device generates a first response message based on the SIP request message.

[0048] Step 4: The lower-level domain obtains the second request header of the first response message; parses the second request header and extracts the second target information of the first response message; obtains the first target information of the upper-level platform, replaces the second target information of the second request header with the first target information, and sends the replaced second request header to the cache middleware.

[0049] Step 5: The upper domain searches the cache middleware for the replaced second request header corresponding to the SIP request message, extracts the replaced second request header for assembly, and generates a second response message to the SIP request message.

[0050] Step 6: The upper domain uses the SipProvider interface of the Jani-sip protocol stack to send the second response message to the corresponding upper platform.

[0051] In this preferred embodiment, by bypassing the Jani-sip protocol stack's processing of requests, responses, transactions, and dialog boxes, and bypassing the management of the session life cycle, a SIP message sending method without session state is implemented, thereby achieving concise and efficient cross-platform SIP service message interaction.
