[0035] This embodiment provides a message transmission method based on the Session Initiation Protocol (SIP), which is used for any one service node in the SIP signaling service cluster, wherein the SIP signaling service cluster includes at least two service nodes. Figure 2This is a flowchart of the message transmission method based on the session initiation protocol in this embodiment, as follows: Figure 2 As shown, the process includes the following steps:

[0036] Step S210: After receiving the service request distributed by the service gateway, the service request is converted into a first session initialization protocol instruction, and then the first session initialization protocol instruction is sent to the session initialization protocol interaction object. At the same time, the first session initialization protocol instruction is stored in the distributed cache middleware.

[0037] The Session Initiation Protocol (SIP) signaling service cluster includes at least two service nodes, which may include a load balancer, such as Nginx, HAProxy, or Linux Virtual Server. The service gateway can receive service requests from web or mobile clients. These service requests may be related to services such as video recording list queries. The SIP interaction object can be a device conforming to the GB / T 28181 standard, such as a network camera or network video recorder. The distributed caching middleware can provide high-performance, high-availability, and high-capacity caching access capabilities, such as Redis, Memcached, or Couchbase. It should be noted that any service node in the aforementioned SIP signaling service cluster can be a specific service node determined through load balancing within the SIP signaling service cluster.

[0038] Specifically, the business gateway forwards the business request sent by the client to the Session Initiation Protocol (SIP) signaling service cluster. Through load balancing within the SIP signaling service cluster, the request is then forwarded to a currently healthy service node with relatively low load. This service node converts the business request from the business gateway into a first SIP instruction. This first SIP instruction includes a start line, a header, and a body. The start line represents the request and response, the header contains a series of header fields, and the body contains content related to the business request; for example, the header fields could be Via, From, or Call-ID. Subsequently, the service node sends this first SIP instruction to the SIP interaction object and simultaneously stores it in a distributed cache middleware.

[0039] Step S220: After receiving the receive response sent by the session initialization protocol interaction object for the first session initialization protocol instruction, the first session initialization protocol instruction is removed from the distributed cache middleware. After receiving multiple second session initialization protocol instructions sent by the session initialization protocol interaction object in sequence, the multiple second session initialization protocol instructions are stored in the distributed cache middleware respectively. The second session initialization protocol instruction is the instruction generated by the session initialization protocol interaction object after performing business processing on the business request.

[0040] After receiving the first session initiation protocol instruction, the session initiation protocol interaction object sends the received response to the service node executing step S210. Based on this response, the service node executing step S210 removes the first session initiation protocol instruction from the distributed cache middleware.

[0041] After processing a business request, the session initiation protocol interaction object generates a second session initiation protocol instruction. This instruction is then sent to the session initiation protocol signaling service cluster. Through load balancing, the cluster distributes the instruction to a healthy service node with relatively low load. This service node then stores the instruction in a distributed cache middleware. In this way, each second session initiation protocol instruction generated by the session initiation protocol interaction object after processing a business request can be stored in the distributed cache middleware. The service node used in each operation can be different.

[0042] Step S230: Based on the protocol header content of the second session initialization protocol instruction, determine and read the second session initialization protocol instructions stored in the same batch in the distributed cache middleware.

[0043] The service node stores the second session initialization protocol instruction in the distributed cache middleware by using the header content of the second session initialization protocol instruction as the key and the body content of the second session initialization protocol instruction as the value to form a key-value pair. Specifically, the service node stores the second session initialization protocol instruction in the distributed cache middleware by using the device code and instruction service code in the header content of the second session initialization protocol instruction as the key and the body content of the second session initialization protocol instruction as the value to form a key-value pair.

[0044] Multiple second session initialization protocol instructions generated by the session initialization protocol interaction object after processing the same business request have the same protocol header content and belong to the same batch; multiple second session initialization protocol instructions generated by the session initialization protocol interaction object after processing different business requests have different protocol header content and do not belong to the same batch.

[0045] Therefore, based on the device code and instruction service code in the protocol header of the second session initial protocol instruction, the second session initial protocol instructions in the same batch stored in the distributed cache middleware can be determined and read.

[0046] The reading method can be either timed fetching or asynchronous notification. Timed fetching involves reading the same batch of second session initial protocol instructions stored in the distributed cache middleware at regular intervals, which is completed by a timed task. Asynchronous notification involves obtaining the number of second session initial protocol instructions sent by the session initial protocol interaction object based on the protocol header content of the second session initial protocol instructions. When the service node determines that the session initial protocol interaction object has finished sending, the service node directly reads the same batch of second session initial protocol instructions stored in the distributed cache middleware.

[0047] Step S240: Convert the second session initialization protocol instructions read from the same batch into a request result and send the request result to the business gateway.

[0048] After the service node reads the second session initialization protocol instructions in the same batch, it performs business processing on the read second session initialization protocol instructions in the same batch according to the business request, obtains the request result, and sends the request result to the business gateway.

[0049] Specifically, after the service node reads the second session initialization protocol instructions in the same batch, it can sort the read second session initialization protocol instructions in the same batch according to the business request, and send the sorted result to the business gateway, which then sends the result to the client.

[0050] Through the above steps S210 to S240, compared with related technologies, this application, after receiving a service request distributed by the service gateway, converts the service request into a first session initialization protocol instruction by any service node in the session initialization protocol signaling service cluster, sends the first session initialization protocol instruction to the session initialization protocol interaction object, and simultaneously stores the first session initialization protocol instruction in the distributed cache middleware; after receiving the receive response sent by the session initialization protocol interaction object for the first session initialization protocol instruction, the first session initialization protocol instruction is removed from the distributed cache middleware, and after sequentially receiving multiple second session initialization protocol instructions sent by the session initialization protocol interaction object, the multiple second session initialization protocol instructions are stored in the distributed cache middleware respectively; the second session initialization protocol instruction is the instruction generated by the session initialization protocol interaction object after performing business processing on the service request; based on the protocol header content of the second session initialization protocol instruction, the same batch of second session initialization protocol instructions stored in the distributed cache middleware is determined and read; the read same batch of second session initialization protocol instructions are converted into request results and sent to the service gateway. It can break the strong binding relationship between the session initiation protocol interaction object and the session initiation protocol signaling service node, reduce the difficulty of horizontal expansion of the session initiation protocol signaling service, and increase the device capacity of a single service node.

[0051] In one embodiment, storing the first session initiation protocol instruction to a distributed cache middleware includes:

[0052] Using the header content of the first session initialization protocol instruction as the key and the body content of the first session initialization protocol instruction as the value, a key-value pair is formed and stored in the distributed cache middleware; the distributed cache middleware stores session initialization protocol instructions corresponding to different protocol header contents.

[0053] Specifically, the service node uses the request code in the header of the first session initial protocol instruction as the key and the protocol body of the first session initial protocol instruction as the value to form a key-value pair, and stores the first session initial protocol instruction in the distributed cache middleware.

[0054] By storing the first session initialization protocol command in a distributed cache middleware, the service node can resend the first session initialization protocol command if it fails to do so.

[0055] In one embodiment, moving the first session initiation protocol instruction out of the distributed cache middleware includes:

[0056] Based on the header content of the first session initialization protocol instruction, determine the session initialization protocol instruction to be removed from the distributed cache middleware, and remove the session initialization protocol instruction to be removed from the distributed cache middleware.

[0057] Specifically, the service node determines the session initialization protocol instruction to be removed from the distributed cache middleware based on the request code in the protocol header of the first session initialization protocol instruction, and removes the session initialization protocol instruction to be removed from the distributed cache middleware.

[0058] By moving the initial protocol instruction of the first session out of the distributed cache middleware, the distributed cache middleware can have more storage space.

[0059] In one embodiment, the multiple second session initialization protocol instructions stored in the distributed caching middleware are all stored with the same protocol header content corresponding to the multiple second session initialization protocol instructions as the key and the protocol body content corresponding to each second session initialization protocol instruction as the value.

[0060] Specifically, the multiple second session initialization protocol instructions stored in the distributed caching middleware are all stored with the device code and instruction service code in the same protocol header content corresponding to the multiple second session initialization protocol instructions as keys, and the protocol body content corresponding to each second session initialization protocol instruction as values.

[0061] By storing the same protocol header content corresponding to multiple second session initialization protocol instructions as the key and the protocol body content corresponding to each second session initialization protocol instruction as the value, these multiple second session initialization protocol instructions can be associated.

[0062] In one embodiment, the message transmission method based on the session initiation protocol may further include:

[0063] If no receive response is received from the session initiation protocol interaction object, the first session initiation protocol instruction stored in the distributed cache middleware is read according to the protocol header content of the first session initiation protocol instruction, and the first session initiation protocol instruction is resent to the session initiation protocol interaction object until a receive response is received from the session initiation protocol interaction object.

[0064] Specifically, if the service node does not receive a receive response from the session initialization protocol interaction object within the set time range, it is considered that the service node has not received a receive response from the session initialization protocol interaction object. Based on the request code in the header of the first session initialization protocol instruction, the service node reads the first session initialization protocol instruction stored in the distributed cache middleware. According to the retry policy, the service node resends the first session initialization protocol instruction to the session initialization protocol interaction object until a receive response is received from the session initialization protocol interaction object. The retry policy can specify the number of retries and the retry interval.

[0065] By reading the first session initialization protocol instruction stored in the distributed cache middleware according to the protocol header content of the first session initialization protocol instruction, and resending the first session initialization protocol instruction to the session initialization protocol interaction object until a receive response is received from the session initialization protocol interaction object, the situation where the service node fails to send the first session initialization protocol instruction can be resolved.

[0066] This embodiment also provides a session initiation protocol signaling service cluster 30, such as Figure 3 As shown, it includes at least two service nodes 302, which are used to execute the message transmission method provided in any of the above embodiments. This Session Initiation Protocol (SIP) signaling service cluster 30 can decouple the strong binding relationship between the SIP interaction object and the SIP signaling service node, reducing the difficulty of horizontal scaling of the SIP signaling service and increasing the device capacity of a single service node.

[0067] In one embodiment, the service node 302 includes a message aggregation module 303 and a message retry module 304. The message aggregation module 303 is used to aggregate session initialization protocol instructions in the same batch and can associate multiple session initialization protocol instructions in the same batch. The message retry module 304 is used to resend session initialization protocol instructions and can resolve the situation where the session initialization protocol instructions fail to be sent.

[0068] Among them, the message aggregation module 303 is responsible for determining and reading the same batch of second session initial protocol instructions stored in the distributed cache middleware according to the protocol header content of the second session initial protocol instructions; and is responsible for converting the read second session initial protocol instructions of the same batch into request results and sending the request results to the business gateway.

[0069] The message retry module 304 is responsible for storing the first session initialization protocol instruction in the distributed cache middleware; and for performing different processing based on the response of the session initialization protocol interaction object to the first session initialization protocol instruction. Specifically, when the session initialization protocol interaction object sends a receive response to the first session initialization protocol instruction, this module removes the first session initialization protocol instruction from the distributed cache middleware; when the session initialization protocol interaction object does not send a receive response to the first session initialization protocol instruction, this module first reads the first session initialization protocol instruction from the distributed cache middleware and then resends the first session initialization protocol instruction.

[0070] This embodiment also provides a message transmission system 40 based on a session initiation protocol, such as... Figure 4 As shown, it includes a distributed caching middleware 41, a service gateway 42, and a session initiation protocol signaling service cluster 30 provided in the above embodiments.

[0071] This embodiment also provides an electronic device including a memory and a processor, the memory storing a computer program and the processor being configured to run the computer program to perform the steps in any of the above method embodiments.

[0072] Optionally, the electronic device may further include a transmission device and an input / output device, wherein the transmission device is connected to the processor and the input / output device is connected to the processor.

[0073] Optionally, in this embodiment, the processor can be configured to perform the following steps via a computer program:

[0074] S1, after receiving the business request distributed by the business gateway, converts the business request into a first session initialization protocol instruction, sends the first session initialization protocol instruction to the session initialization protocol interaction object, and stores the first session initialization protocol instruction in the distributed cache middleware.

[0075] S2, after receiving the receive response sent by the session initialization protocol interaction object in response to the first session initialization protocol instruction, the first session initialization protocol instruction is removed from the distributed cache middleware, and after receiving multiple second session initialization protocol instructions sent by the session initialization protocol interaction object in sequence, the multiple second session initialization protocol instructions are stored in the distributed cache middleware respectively; the second session initialization protocol instruction is the instruction generated by the session initialization protocol interaction object after performing business processing on the business request;

[0076] S3, based on the protocol header content of the second session initial protocol instruction, determine and read the same batch of second session initial protocol instructions stored in the distributed cache middleware;
