[0028] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] In the description of the invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] It should be noted that SIP (Session Initialization Protocol) is a multimedia communication protocol developed by IETF (Internet Engineering Task Force). SIP is an IP voice session control protocol originating from the Internet, which has the characteristics of flexibility, easy implementation and easy expansion.

[0031] Although the GB28181 protocol is an extension of the SIP protocol, there are also major differences.

[0032] Generally, the SIP protocol is used for end-to-end voice and video calls, so routing is mostly based on transactions or sessions (calls). Video surveillance equipment usually uses the national standard 28181 protocol for access.

[0033] As the scale of access to video surveillance equipment is growing explosively, the traditional single-point or active-standby signaling deployment methods can no longer meet actual needs. In addition, traditional signaling deployment systems are usually built based on the SIP protocol, mainly designed for end-to-end network (VOIP) telephones, and are difficult to meet the requirements of the national standard 28181 protocol.

[0034] In this regard, the present invention provides a signaling transmission system. The signaling transmission system provided by the present invention complies with the requirements of the national standard 28181 protocol, and maximizes access performance by separating access services from load balancing and forwarding transactions of the same device to the same application node, thereby better meeting the signaling deployment requirements between massive video surveillance devices.

[0035] Figure 1 This is one of the structural diagrams of the signaling deployment system provided by the present invention. Figure 1 The signaling deployment system provided by the present invention is described. Figure 1 As shown, the signaling deployment system includes: an access service module 101 and a load balancing module 102; the access service module 101 and the load balancing module 102 are communicatively connected.

[0036] The access service module 101 is used to forward the application request message to the load balancing module 102 when receiving the application request message sent by the target device.

[0037] It should be noted that, when a traditional SIP proxy receives a SIP message, it usually needs to parse the message header of the SIP message to obtain the next route, which reduces the load performance. The general four-layer load balancing is difficult to meet the transaction requirements of signaling messages.

[0038] Therefore, the signaling deployment system provided by the present invention separates access service and load balancing through the access service module 101 and the load balancing module 102, thereby maximizing the access performance.

[0039] Specifically, the target device is an electronic device that has successfully registered in the signaling deployment system. The signaling deployment system provided by the present invention can deploy the signaling sent by the target device.

[0040] It should be noted that the target device in the embodiment of the present invention may be a video surveillance device, or may be other electronic devices that require signaling deployment.

[0041] When there is a signaling deployment requirement, the target device may send an application request message to the access service module 101 in the signaling deployment system.

[0042] After receiving the application request message sent by the target device, the access service module 101 may forward the application request message to the load balancing module 102 in the signaling deployment system.

[0043] Optionally, in the embodiment of the present invention, the number of the access service modules 101 is one or more.

[0044] Optionally, the application request message sent by the target device in the embodiment of the present invention may be a SIP message and an HTTP message of the UDP protocol or the TCP protocol, thereby improving external integration and secondary development capabilities.

[0045] Among them, the UDP protocol (User Datagram Protocol) is a connectionless transport layer protocol in the OSI (Open System Interconnection) reference model, which can provide transaction-oriented information transmission services.

[0046] The TCP protocol (Transmission Control Protocol) is a connection-oriented, reliable, byte stream-based transport layer communication protocol.

[0047] The load balancing module 102 is used to receive application request messages, and forward the application request messages to the application service node 103 corresponding to the target device based on the identity identifier of the target device as a routing condition, so that the application service node 103 corresponding to the target device can process the application request messages based on the national standard 28181 protocol.

[0048] Specifically, the load balancing module 102 may receive an application request message sent by the access service module 101 .

[0049] After receiving the application request message, the load balancing module 102 may obtain the identity of the target device that sends the application request message by parsing the message header of the application request message.

[0050] After the load balancing module 102 obtains the identity of the target device, it can use the identity of the target device as a routing condition to forward the application request message to the application service node 103 corresponding to the target device, thereby achieving transaction processing of the same target device on the same application service node 103, and simplifying complex transaction logic.

[0051] After receiving the application service message forwarded by the load balancing module 102 , the application service node 103 corresponding to the target device may process the application service message based on the national standard 28181 protocol.

[0052] It should be noted that the application service node 103 corresponding to the target device may be predetermined based on prior knowledge and / or actual conditions; the application service node 103 corresponding to the target device may also be allocated to the target device by the signaling deployment system after the target device is registered in the signaling deployment system. The application service node 103 corresponding to the target device is not limited in the embodiment of the present invention.

[0053] Optionally, the number of the load balancing modules 102 in the embodiment of the present invention may be one or more.

[0054] Based on the contents of the above embodiments, the access service module 101 is constructed based on four-layer load balancing.

[0055] It should be noted that the four-layer load balancing usually uses the IP plus port method for routing forwarding; the seven-layer load balancing performs proxy forwarding based on the request URL address. The four-layer load architecture design is relatively simple, without the need to parse the specific message content, and the network throughput and processing power will be relatively high, while the advantages of the seven-layer load balancing are reflected in its multiple functions and flexible and powerful control.

[0056] Optionally, the access service module 101 in the embodiment of the present invention can be constructed based on four-layer load balancing, and can support TCP, UDP, TLS and other data packet access, and provide a variety of load strategies based on IP (Internet Protocol), such as polling, weight, hash (hash function, also known as hash), source address, etc.

[0057] Among them, TLS (Transport Layer Security) is a security protocol that aims to provide security and data integrity protection for Internet communications.

[0058] Based on the contents of the above embodiments, the load balancing module 102 is constructed based on seven-layer load balancing.

[0059] Optionally, the load balancing module 102 in the embodiment of the present invention can be constructed based on a seven-layer load balancing, can parse and process and distribute SIP messages and HTTP(s) messages, and can perform routing, cross-domain, real address and other processing.

[0060] The signaling transmission system in the embodiment of the present invention includes an access service module and a load balancing module that are communicatively connected. The access service module forwards the application request message received from the target user to the load balancing module. The load balancing module uses the identity identifier of the target device as a routing condition and forwards the application request message to the application service node corresponding to the target device, so that the application service node corresponding to the target device can process the application request message based on the national standard 28181 protocol. By separating the access service from the load balancing and forwarding the transactions of the same device to the same application service node for processing, the access performance can be maximized, and unlimited horizontal expansion between the signaling transmission system and the application service node can be achieved, which can better meet the signaling deployment requirements between massive video surveillance devices.

[0061] Based on the contents of the above embodiments, the access service module 101 is further configured to forward the registration request message to the load balancing module 102 when receiving the registration request message sent by any device.

[0062] Specifically, any device in the embodiments of the present invention may be an electronic device that requests the signaling deployment system provided by the present invention to perform signaling deployment. Any of the above devices may be a video surveillance device, or may be other electronic devices.

[0063] When any device that is not registered in the signaling deployment system has a signaling deployment requirement based on the signaling deployment system, the device may send a registration request message to a service access unit in the signaling deployment system.

[0064] After receiving the registration request message sent by the above device, the access service unit may forward the above registration request message to the load balancing module 102 .

[0065] Optionally, the registration request message sent by any device in the embodiment of the present invention may be a SIP message and an HTTP message of the UDP protocol or the TCP protocol.

[0066] The load balancing module 102 is also used to register any device when receiving and responding to a registration request message. After any device is successfully registered, any device is determined as a target device, and based on the number of target devices corresponding to each currently available application service node 103, the application service node 103 corresponding to the target device is determined.

[0067] Specifically, the load balancing module 102 may receive a registration request message sent by any device sent by the access service module 101 .

[0068] After receiving the registration request message, the load balancing module 102 may register the device in response to the registration request message.

[0069] Optionally, the load balancing module 102 may return an authentication request message to the device in response to the registration request message. After receiving the authentication request message sent by the load balancing module 102, the device may return an authentication confirmation message corresponding to the authentication request message to the load balancing module 102. After receiving the authentication confirmation message, the load balancing module 102 may authenticate the device based on the authentication confirmation message, and may confirm that the device is successfully registered if the authentication is successful.

[0070] After the load balancing module 102 confirms that the device is successfully registered, the load balancing module 102 may determine the device as a target device.

[0071] After the load balancing module 102 determines the above device as the target device, it can determine the currently available application service node 103 corresponding to the least number of target devices as the application service node 103 corresponding to the above target device based on the number of target devices corresponding to each currently available application service node 103.

[0072] Optionally, the load balancing module 102 may also obtain the identity and / or the number of channels of the target device, and may perform conditional judgment based on the identity and / or channel data of the target device, so as to determine the application service node 103 corresponding to the target device based on the result of the conditional judgment. For example, the application service node 103 corresponding to the target device associated with the target device may be determined based on the identity of the target device, so that the application service node 103 corresponding to the target device associated with the target device may be determined as the application service node 103 corresponding to the target device; or, the application service node 103 corresponding to the target device with the same number of channels as the target device may be determined based on the number of channels of the target device, so that the application service node 103 corresponding to the target device with the same number of channels as the target device may be determined as the application service node 103 corresponding to the target device.

[0073] In the embodiment of the present invention, after the access service module receives the registration request message sent by any device, the registration request message is forwarded to the load balancing module. After receiving the registration request message, the load balancing module registers the device. After the device is successfully registered, the device is determined as a target device, and based on the number of target devices corresponding to each available application service node, the application service node corresponding to the target device is determined, which can improve the security of the signaling deployment system.

[0074] Based on the contents of the above embodiments, the load balancing module 102 is further configured to update the corresponding relationship between the target device and the application service node 103 in the current period based on the activation information received in the current period.

[0075] Specifically, after each application service node 103 is started, it will periodically send activation information to the load balancing module 102 .

[0076] The load balancing module 102 may determine currently available application service nodes 103 and currently unavailable application service nodes 103 among the application service nodes 103 based on the activation information received in the current period.

[0077] After the load balancing module 102 determines the currently available application service node 103 and the currently unavailable application service node 103, it can cancel the correspondence between the currently unavailable application service node 103 and the corresponding target device, and allocate the target device corresponding to the currently unavailable application service node 103 to the currently available application service node 103, establish the correspondence between the above target device and the currently available application service node 103, thereby realizing the update of the correspondence between the target device and the application service node 103 of the current period.

[0078] Optionally, after the load balancing module 102 determines the currently available application service nodes 103 and the currently unavailable application service nodes 103, the corresponding relationship between the currently unavailable application service nodes 103 and the corresponding target devices can be released, and based on the number of target devices corresponding to each currently available application service node 103, the target devices corresponding to the currently unavailable application service nodes 103 can be allocated to one or more currently available application service nodes 103 with the least number of corresponding target devices, and a corresponding relationship between the above-mentioned target devices and the above-mentioned one or more currently available application service nodes 103 with the least number of corresponding target devices can be established.

[0079] The load balancing module in the embodiment of the present invention is also used to update the corresponding relationship between the target device and the application service node in the current period based on the activation information received in the current period, which can further improve the availability and deployment efficiency of the signaling deployment system.

[0080] Based on the contents of the above embodiments, there are multiple access service modules 101 and / or there are multiple load balancing modules 102.

[0081] Figure 2 This is the second structural diagram of the signaling deployment system provided by the present invention. Figure 2 As shown, there may be multiple access service modules 101 and multiple load balancing modules 102.

[0082] In the embodiment of the present invention, the number of access service modules 101 and / or load balancing modules 102 in the signaling deployment system is multiple, and the signaling deployment system can realize distributed cluster deployment of signaling, which can further improve the availability and deployment efficiency of the signaling deployment system.

[0083] Based on the contents of the above embodiments, when there are multiple access service modules 101, the access service modules 101 are constructed based on the four-layer load balancing and keepalived components.

[0084] It should be noted that, when there are multiple access service modules 101 in the signaling deployment system, the access service modules 101 can be constructed based on a four-layer load balancing, and configured with a keepalived component to achieve high availability in the active-standby mode and provide a unified virtual address access to the outside.

[0085] Among them, keepalived is a component similar to the layer3, 4&5 switching mechanism, which is what we usually call layer 3, layer 4, and layer 5 switching. Keepalived can be used to detect the status of the server to ensure high availability of the cluster.

[0086] Based on the contents of the above embodiments, the load balancing module 102 is also configured to store the identity of the target device and the number of channels in the shared memory.

[0087] Specifically, after the load balancing module 102 successfully registers the device in response to a registration request message sent by any device and determines the device as a target device, it can also obtain the identity and channel number of the target device and store the target identity and channel number in a shared memory.

[0088] It should be noted that the shared memory in the embodiment of the present invention may be a local memory or a cloud memory. The shared memory in the embodiment of the present invention is not specifically limited.

[0089] Optionally, the shared memory in the embodiment of the present invention may be a redis memory.

[0090] Among them, Redis (Remote Dictionary Server) is an open source log-type, Key-Value database written in ANSI C language, supporting the network, memory-based and persistent, and providing APIs in multiple languages.

[0091] Optionally, the load balancing module 102 may also send information such as the correspondence between the application service node 103 and the target device and / or the identity of the currently available application service node 103 to the shared memory for storage.

[0092] The load balancing module in the embodiment of the present invention is also used to store the identity of the target device and the number of channels in the shared memory, which can achieve smooth expansion of the signaling deployment system.

[0093] Figure 3 is a flow chart of the signaling deployment method provided by the present invention. The signaling deployment method described below and the signaling deployment system provided by the present invention described above can be referred to each other. Figure 3 As shown, the method includes: Step 301, when the access service module receives an application request message sent by a target device, the access service module forwards the application request message to a load balancing module.

[0094] Specifically, the target device is an electronic device that has successfully registered in the signaling deployment system. The signaling deployment system provided by the present invention can deploy the signaling sent by the target device.

[0095] It should be noted that the target device in the embodiment of the present invention may be a video surveillance device, or may be other electronic devices that require signaling deployment.

[0096] When there is a signaling deployment requirement, the target device can send an application request message to the access service module in the signaling deployment system.

[0097] After receiving the application request message sent by the target device, the access service module may forward the application request message to the load balancing module in the signaling deployment system.

[0098] Step 302: After receiving the application request message, the load balancing module forwards the application request message to the application service node corresponding to the target device based on the identity identifier of the target device as a routing condition, so that the application service node corresponding to the target device processes the application request message based on the national standard 28181 protocol.

[0099] Specifically, the load balancing module may receive an application request message sent by the access service module.

[0100] After receiving the application request message, the load balancing module can obtain the identity of the target device that sends the application request message by parsing the message header of the application request message.

[0101] After the load balancing module obtains the identity of the target device, it can use the identity of the target device as a routing condition to forward the application request message to the application service node corresponding to the target device, thereby achieving the completion of transaction processing for the same target device at the same application service node, and simplifying complex transaction logic.

[0102] After receiving the application service message forwarded by the load balancing module, the application service node corresponding to the target device may process the application service message based on the national standard 28181 protocol.

[0103] The embodiment of the present invention forwards the application request message sent by the target user to the load balancing module through the access service module. The load balancing module uses the identity identifier of the target device as the routing condition and forwards the application request message to the application service node corresponding to the target device, so that the application service node corresponding to the target device can process the application request message based on the national standard 28181 protocol. By separating the access service from the load balancing and forwarding the transactions of the same device to the same application service node for processing, the access performance can be maximized, and unlimited horizontal expansion between the signaling transmission system and the application service node can be achieved, which can better meet the signaling deployment requirements between massive video surveillance devices.
