Description

Technical Field

[0001] The present invention belongs to the field of remote information transmission technology, and in particular to a remote file transmission method, device and electronic equipment based on the SIP protocol. Background Art

[0002] GB28181 is a Chinese national standard, "Technical Requirements for Information Transmission, Exchange and Control of Public Security Video Surveillance Networking Systems" (GB / T 28181-2016). This standard proposes an interconnection framework and specification for video surveillance systems in the public security field, solving the compatibility and interoperability issues of video surveillance equipment between different manufacturers and different platforms. The implementation of GB28181 is of great significance to the standardization and standardization of my country's video surveillance industry, as well as public security protection and smart city construction. It not only improves the utilization rate of video surveillance resources, but also provides a standardized data source interface for intelligent video analysis and big data applications.

[0003] The control signaling layer in the GB28181 protocol uses the SIP (Session Initiation Protocol) protocol for device registration, deregistration, heartbeat maintenance, session establishment and control, etc. The SIP transmission method can be implemented based on UDP and TCP, but most traditional devices only support UDP transmission. The current video transmission network built based on the GB28181 protocol, because the network layer construction mostly performs MTU slicing on the message, there will be information truncation and reorganization problems for hypertext and file control operations of devices that exceed the MTU fragment length. The current SIP protocol stack does not support data reorganization at the application layer. For such operations, the device hypertext and file control operations designed based on the GB28181 protocol need to design interfaces separately to implement multi-page design at the application layer, which greatly increases the design of the SIP architecture.

[0004] Therefore, when constructing a video transmission platform based on GB28181 implemented in the SIP protocol, a universal method for remotely controlling hypertext and file transmission of video terminal devices is urgently needed to simplify the transmission of hypertext and files in the SIP system. Summary of the invention

[0045] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only 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.

[0046] In video surveillance scenarios based on SIP (Session Initiation Protocol), remote transmission of hypertext (such as HTML) and files has practical application value, and can realize remote interaction, file transmission and management functions in video surveillance scenarios. The SIP protocol is mainly used to establish, modify and terminate multimedia sessions. In video surveillance scenarios, SIP can not only support the transmission of audio and video data, but also assist in the transmission of files and texts.

[0047] The present invention provides a remote file transmission method, device and electronic device based on the SIP protocol through the following embodiments, which enables a video terminal device and a source platform to complete remote file transmission based on a standard SIP protocol framework.

[0048] See also Figure 1 An embodiment of the present invention describes a remote file transmission method based on the SIP protocol from the perspective of a SIP server, comprising the following steps:

[0049] Step S110: Receive a first file delivery instruction sent by a source end using a first communication method, where the first file delivery instruction at least includes a first file storage address.

[0050] In this step, the first file storage address points to the address (such as URL or network path) of the storage location of the target file, and the terminal can access and download the target file through this address. The source end, such as the operation and maintenance platform or the control end, sends a file remote transmission instruction to the target terminal through the SIP server. The source end does not send the target file itself, but sends the storage address of the target file, and forwards the instruction to the terminal through the SIP server. Therefore, the source end will carry the file storage address of the target file in the instruction. In this way, the source end can remotely send hypertext and files such as view library configuration files and long text configuration information to the terminal.

[0051] In a further embodiment, the first file delivery instruction may also include information such as file type or format, file size, checksum, etc., to ensure that the terminal can correctly identify and process the file, or verify the integrity of the file.

[0052] Step S120: Send a second file sending instruction to the terminal using a second communication method according to the first file sending instruction, wherein the second file sending instruction at least includes the first file storage address, so that the terminal obtains the target file from the first file storage address.

[0053] In this step, the SIP server parses key information, especially the first file storage address, from the first file distribution instruction, and constructs a second file distribution instruction based on the parsed information, wherein the instruction content at least includes the storage address of the target file, and sends the second file distribution instruction to the terminal through the second communication method, so that the terminal can obtain the file from the file storage address specified by the source end according to the instruction.

[0054] This embodiment issues instructions through the SIP server transferring files, which can flexibly adapt to the access requirements of various terminal devices, and has a clear process and is easy to expand.

[0055] In a further embodiment, the first communication mode and the second communication mode can be selected according to specific network requirements, and they can be the same communication protocol or different communication protocols, and the selection of these communication protocols can be SIP MESSAGE method, HTTP method, push protocol, etc. Exemplarily, the first communication mode adopted by the source end is HTTP REST method, so that the SIP server reads instruction information from a stable and reliable HTTP RESTFUL long connection, and the second communication mode adopted by the SIP server can select the MESSAGE method in the SIP protocol to establish a short connection for instant messaging.

[0056] In a further embodiment, the source end may also carry a first notification request in the first file delivery instruction, that is, complete notification enabling. When the instruction carries a notification request, the SIP server needs to notify the source end of the file reception result of the terminal, that is, the first response information.

[0057] Similarly, the SIP server may carry a second notification request in the second file distribution instruction sent to the terminal, so that the terminal needs to return the file reception result of the remote transmission process, ie, second response information, to the SIP server.

[0058] It is understandable that if the first file delivery instruction does not carry a notification request, the SIP server can still carry a notification request in the second file delivery instruction, and the SIP server can receive the file reception result returned by the terminal but does not need to notify the source end. If both the first file delivery instruction and the second file delivery instruction carry a notification request, the SIP server can generate a first response message based on the file reception result returned by the terminal and then notify the source end.

[0059] For example, Figure 2 As shown, it illustrates an interactive process of remote file transmission based on the SIP protocol provided by an embodiment of the present invention, including the following session flow:

[0060] Step S201: The source end sends a first remote hypertext and file delivery command to the SIP server, where the command is carried using the HTTP REST method.

[0061] Step S202. After receiving the first remote command to send the hypertext and file, the SIP server returns a SIP response message 200 OK to the source end;

[0062] Step S203: The SIP server sends a second remote hypertext and file delivery command to the terminal, and the command is carried in the SIP MESSAGE method.

[0063] Step S204: After receiving the command, the terminal returns a SIP response message 200 OK.

[0064] Step S205: The terminal obtains the hypertext and files from the HTTP server from the address specified by the source, and the transmission method adopts HTTPS.

[0065] Step S206: After the terminal completes the hypertext and file transmission, since the second remote hypertext and file transmission command in step S203 is configured with completion notification enable, the terminal needs to send a file reception notification to the SIP server.

[0066] Step S207: The SIP server replies a SIP response message 200 OK to the terminal.

[0067] Step S208: The first remote hypertext and file command is configured with completion notification enabled, and the SIP server notifies the source end of the file reception result.

[0068] Step S209: The source end replies a SIP response message 200 OK to the SIP server.

[0069] In a further embodiment, the source end may request the terminal to collect the target file through the SIP server, and the terminal stores the requested file to a designated address, and the source end may subsequently access it from the designated address.

[0070] Specifically, Figure 3 As shown, an embodiment of the present invention describes a remote file transmission method based on the SIP protocol from the perspective of a SIP server, comprising the following steps:

[0071] Step S310: Receive a first file request instruction sent by the source end using a third communication method, where the first file request instruction at least includes a second file storage address.

[0072] In this step, the second file storage address points to the address (such as URL or network path) of the storage location of the target file, and the terminal can upload the target file requested by the source end through this address. Similarly, the target file is not directly transmitted between the source end and the terminal, but the source end informs the file storage address, the terminal uploads the target file according to the specified address, and the source end searches from the specified address to complete the source end remotely collecting the hypertext and files collected by the terminal.

[0073] In a further embodiment, the first file request instruction may also include information such as a request identifier, a file type, and a priority level.

[0074] Step S320: Send a second file request instruction to the terminal using the fourth communication method according to the first file request instruction, the second file request instruction at least including a second file storage address, so that the terminal stores the file requested by the source end to the second file storage address.

[0075] In this step, the SIP server parses key information from the first file request instruction, especially the second file storage address, and constructs a second file request instruction based on the parsed information, wherein the instruction content at least includes the file storage address, and sends the second file request instruction to the terminal via the fourth communication method, so that the terminal can upload the file at the file storage address specified by the source end according to the instruction.

[0076] In a further embodiment, the third communication mode and the fourth communication mode can be selected according to specific network requirements, and can be the same communication protocol or different communication protocols. The communication protocols can be SIPMESSAGE method, HTTP method, push protocol, etc.

[0077] Similar to the above embodiment, the source end may also carry a third notification request in the first file request instruction, that is, completion notification enablement. When the instruction carries a notification request, the SIP server needs to notify the source end of the file upload result of the terminal, that is, the third response information.

[0078] Similarly, the SIP server may carry a fourth notification request in the second file request instruction sent to the terminal, so that the terminal needs to return the file upload result of the remote transmission process, ie, fourth response information, to the SIP server.

[0079] It is understandable that if the first file request instruction does not carry a notification request, the SIP server can still carry a notification request in the second file request instruction, and the SIP server can receive the file upload result returned by the terminal but does not need to notify the source end. If both the first file request instruction and the second file request instruction carry a notification request, the SIP server can generate response information based on the file upload result returned by the terminal and then notify the source end.

[0080] For example, Figure 4 As shown, it illustrates an interactive process of remote file transmission based on the SIP protocol provided by an embodiment of the present invention, including the following session flow:

[0081] Step S401: The source end sends a first remote hypertext and file collection command to the SIP server, where the command is carried using the HTTP REST method.

[0082] Step S402: After receiving the first remote hypertext and file collection command, the SIP server returns a SIP response message 200 OK to the source end;

[0083] Step S403: The SIP server sends a second remote hypertext and file collection command to the terminal, and the command is carried in the SIP MESSAGE method.

[0084] Step S404: After receiving the command, the terminal returns a SIP response message 200 OK.

[0085] Step S405: The terminal uploads the hypertext and files to the HTTP server from the address specified by the source, and the transmission method adopts HTTPS.

[0086] Step S406: After the terminal completes the transmission of the hypertext and the file, since the second remote collection of hypertext and files command in step S403 is configured with completion notification enabled, the terminal needs to send a file upload notification to the SIP server.

[0087] Step S407: The SIP server replies a SIP response message 200 OK to the terminal.

[0088] Step S408: The first remote collection of hypertext and files command is configured with completion notification enabled, and the SIP server notifies the source end of the file upload result.

[0089] Step S409: The source end replies a SIP response message 200 OK to the SIP server.

[0090] The following further illustrates the remote file transmission method based on the SIP protocol provided by the embodiment of the present invention through the log collection control and subscription process of the operation and maintenance platform and the terminal device.

[0091] like Figure 5 As shown, an embodiment of the present invention provides a method for implementing remote log upload control and subscription based on the SIP protocol, which is divided into log upload control and log upload subscription, including the following session process:

[0092] (1) Log upload control

[0093] Step S501. The operation and maintenance module sends a terminal log upload control command to the SIP platform through the Restful interface.

[0094] Step S502: The SIP platform sends the terminal log upload control command to the terminal device via the SIP signaling of the GB28181 protocol.

[0095] Step S503: The terminal device uploads the terminal device operation status log to the HTTP server via the HTTPS interface.

[0096] Step S504: After the terminal device completes uploading the log, it notifies the SIP platform.

[0097] Step S505: The operation and maintenance module asynchronously checks the relevant logs on the HTTP server.

[0098] (2) Log upload subscription

[0099] Step S506. The operation and maintenance module sends a terminal log upload subscription command to the SIP platform through the Restful interface.

[0100] Step S507: The SIP platform sends the terminal log upload subscription command to the terminal device via the SIP signaling of the GB28181 protocol.

[0101] Step S508: The terminal device periodically uploads the terminal operation status log to the HTTP server through the HTTPS interface according to the setting rules of the subscription command.

[0102] Step S509: After the terminal device completes uploading the log, it notifies the SIP platform.

[0103] Step S510: The operation and maintenance module asynchronously checks the relevant logs on the HTTP server.

[0104] The above embodiments provide a remote file transmission method based on the SIP protocol, which is implemented based on the standard SIP protocol architecture. In the implementation of the service interface, terminal devices of different manufacturers do not need to reconstruct the original national standard architecture. They only need to add a calling framework in the service device interface of the device. The remote hypertext and file transmission between the source end such as the operation and maintenance platform, the control end, etc. and the terminal device such as the camera, the intelligent monitoring terminal, etc. is realized based on the SIP protocol. The source end sends the file storage address to the terminal through the SIP server, so that the terminal obtains the target file according to the file storage address or uploads the file for the source end to query, thereby significantly reducing the workload of the platform implementation, and is promotable between devices of different manufacturers and different platforms.

[0105] The server mentioned above may be a server implemented based on the SIP protocol in each embodiment of the present invention. The server may be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, CDN, and big data and artificial intelligence platforms.

[0106] The disclosed method can be implemented by various devices, so the present invention also discloses a remote file transmission device based on the SIP protocol corresponding to the method, and a specific embodiment is given below for detailed description.

[0108] An instruction receiving module 602 is used to receive a first file sending instruction sent by a source end using a first communication method, where the first file sending instruction at least includes a first file storage address;

[0109] The instruction sending module 604 is used to send a second file sending instruction to the terminal using a second communication method according to the first file sending instruction, and the second file sending instruction at least includes the first file storage address, so that the terminal obtains the target file from the first file storage address.

[0110] In a further embodiment, the instruction receiving module 602 further performs the following process:

[0111] A first file request instruction is received and sent by a source end using a third communication method, where the first file request instruction at least includes a second file storage address.

[0112] In a further embodiment, the instruction sending module 604 further performs the following process:

[0113] A second file request instruction is sent to the terminal using a fourth communication method according to the first file request instruction, the second file request instruction at least including a second file storage address, so that the terminal stores the file requested by the source end to the second file storage address.
