Description

Technical Field

[0001] The present invention relates to the field of communication technologies, and in particular to a 5G message transmission method, device, electronic device, and storage medium. Background Art

[0002] In the 5G SA core network, data services use service-oriented interfaces to support online billing. Online billing provides quota management and usage reporting on demand based on billing information. Data communication between network elements and business support systems uses the HTTP / 2 protocol. Messages are sent in frames, and receiving messages on the server is a continuous process. Framed messages are cached on the server, occupying the server's heap memory. How to effectively combine the received framed messages into a complete message body, resend the failed framed messages and combine them with the successfully sent framed messages to form a complete message body, and immediately release memory brings great difficulties to development.

[0003] like Figure 1 As shown in the figure, in the existing online billing system, network elements send HTTP / 2 message requests in real time. HTTP / 2 messages are divided into header frames and data frames for transmission. After receiving the framed messages, the server needs to reassemble the framed messages and verify the integrity of the messages. This poses the following technical problems:

[0004] 1. Difficulty in assembling messages: The online billing system generates over 2 billion messages per day. After HTTP / 2 frames are sent, the number of framed messages received by the HTTP / 2 server increases exponentially. Quickly assembling framed messages is a major challenge.

[0005] 2. Difficulty in resending framed messages: Framed messages are cached in the server's private memory until the last frame is received, occupying the server's memory. If the memory is not released in time, the server will experience an OOM (Out of Memory) exception, resulting in message loss and subsequent message requests failing. This will cause the online billing system to be unable to provide normal services.

[0006] 3. Difficulty in message management: After the server successfully assembles a message, it must verify its integrity and validity and send data that complies with business specifications to the logic processing unit. Given the massive amount of messages generated daily, how to quickly determine the correctness of the messages and generate statistics on valid and invalid messages is a major challenge.

[0007] 4. Difficulties in operation and maintenance management: For the massive amount of messages received every day, after being processed by the online billing system, how to intuitively and effectively display the real-time processing indicator data of the messages and provide efficient operation and maintenance management and alarm notifications are essential functions.

[0021] All assembled complete messages are checked. If they are determined to be valid JSON strings, 5G service processing continues.

[0022] Otherwise, if it is judged to be an invalid message, an invalid status identification code is returned.

[0023] In one embodiment, if it is determined that the message is not the last frame, then continuing to receive the framed message specifically includes:

[0024] If it is determined that not all framed messages have been received within the preset delay threshold, the client is notified to send the missing messages; otherwise, the client continues to receive framed messages.

[0025] In one embodiment, it further includes:

[0026] After the framed message is assembled, the 5G online charging system executes the online charging rule processing and deletes the framed message from the cache in real time after the processing is completed;

[0043] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0044] In response to the shortcomings of the existing technology, the present invention proposes an assembly method for 5G message framing transmission based on the HTTP / 2 communication protocol, which adopts the Netty framework and Java NIO multiplexing as the communication processing framework, and designs a high-performance HTTP / 2 protocol server and client based on the TCP transmission protocol.

[0045] It should be noted that the Netty framework is an asynchronous, event-driven network application framework that supports the rapid development of maintainable, high-performance, protocol-oriented servers and clients. Java NIO is a Java-based synchronous, non-blocking I / O model and the foundation of I / O multiplexing. It has been increasingly used in large-scale application servers and has become an effective way to solve high-concurrency, large-scale connection, and I / O processing problems.

[0046] Figure 2 It is a flow chart of the 5G message transmission method provided by the present invention, such as Figure 2 Shown, including:

[0047] 101, receiving an HTTP / 2 message, and determining whether the current framed message in the HTTP / 2 message is the last frame message based on the structure;

[0048] 102. If it is determined to be the last frame message, assemble the framed message and check the integrity of the message.

[0049] Specifically, the 5G message transmission method proposed in the present invention is based on the HTTP / 2 interaction process between the client and the server, such as Figure 3 shown.

[0050] First, the client and the server establish an HTTP / 2 persistent connection. The server receives the client's HTTP / 2 request, assembles the framed message of the HTTP / 2 request, and then verifies the integrity of the HTTP / 2 message. Finally, the server filters out invalid information in the business and returns the processing results after the business is completed to the client. The whole process is as follows: Figure 4 shown.

[0051] If the current frame message is the last frame received, execute the following Figure 5 The judgment branch on the right in the assembly process of the 5G message framing transmission of the HTTP / 2 communication protocol shown in the figure assembles the message and verifies the integrity of the message.

[0052] The present invention proposes a method for HTTP / 2 message framing assembly and framed retransmission applied to 5G communications, so that the server can quickly assemble a complete message body after receiving the framed message, immediately release the memory space occupied by the message, and complete the validity and integrity verification of the message.

[0053] Based on the above embodiment, if it is determined that it is not the last frame message, the framed messages continue to be received.

[0054] Specifically, in Figure 5 In the assembly process of the 5G message framing transmission of the HTTP / 2 communication protocol shown, there is another judgment branch on the left. If it is determined that the current frame message is not the last frame received, the action of continuing to receive messages is executed until the complete message is received.

[0055] In the case of HTTP / 2 framed message transmission failure, the present invention notifies the client to resend the missing framed message by the server, and assembles it into a complete message body with the framed message already received by the server. The function of retransmitting the framed message is achieved through the active notification of the server.

[0056] Based on any of the above embodiments, the method further includes before step 101:

[0057] The structure for storing the HTTP / 2 message is constructed, wherein the structure includes the message unique identifier StreamId, the uniform resource locator identifier URI, the Header frame, the Data frame and the update time.

[0058] Specifically, the HTTP / 2 protocol divides messages into Header frames and Data frames. Through the StreamId identifier, a structure named Http5G is defined on the server side to store HTTP / 2 messages. This structure contains the Header frame and Data frame, the message unique identifier StreamId, the uniform resource locator URI, and the update time. The Http5G structure is as follows: Figure 6 shown.

[0059] The present invention improves upon the message structure of the prior art by adding more message identifiers, making it easier to identify framed messages and enabling the server to identify and verify messages when receiving them.

[0060] Based on any of the above embodiments, step 101 in the method specifically includes:

[0061] After establishing an HTTP / 2 persistent connection with the client, the client's IP address is verified, and the connection is maintained with the client with a valid IP address. The connection channel manager adds the persistent connections with all clients to the connection pool for management, and allocates independent storage space for each persistent connection. The storage space stores the message entity of the 5G message request;

[0062] Determine the stream message end identifier used by the message entity, and if the value of the stream message end identifier is true, the current frame message is the last frame message;

[0063] If the value of the stream message end flag is false, the current frame message is not the last frame message.

[0064] Specifically, after constructing the message structure, when the server program is started, the client actively establishes a TCP long connection with the server through a three-way handshake. After the connection is successfully established, the server verifies the client's IP to determine whether the client's IP is in the legal IP list. For illegal IP requests, the server actively disconnects the client. The server's connection channel manager adds all long connections between the client and the client to the connection pool for management, and allocates a storage space (HashMap) for each long connection to store the message entity of the 5G message request received from the client. The server receives the 5G message request sent by the client in real time, and isolates the resources of the long connections of each client through the connection pool.

[0065] Since an HTTP / 2 server can receive requests from multiple clients, a connection channel manager is added to the server to manage these clients. After the client creates a connection with the server, the server verifies whether the client's IP is legal. For illegal IPs, the server actively disconnects the client. For legal IPs, the server adds the created connection to the connection pool for unified management.

[0066] Here, the 5G message request is the client using the HTTP / 2 POST method type, and the message is a JSON type structure. When the server receives the message, it must verify the requested URI and use the URI parser to verify the correctness of the message URI. It continues to process URIs that comply with 5G business specifications, intercepts illegal requests through the message interceptor, and returns a status code of 400 to the client.

[0067] The present invention adds a method for assembling HTTP / 2 message frames in a framework, and realizes the function of assembling message frames by processing messages passing through the framework.

[0068] Based on any of the above embodiments, step 102 in the method specifically includes:

[0069] Search the storage space for all framed messages having the same message unique identifier StreamId by using the message unique identifier StreamId, and assemble all framed messages into a complete message;

[0070] All assembled complete messages are checked. If they are determined to be valid JSON strings, 5G service processing continues.

[0071] Otherwise, if it is judged to be an invalid message, an invalid status identification code is returned.

[0072] Specifically, it should be noted that a complete message body is uniquely identified by a StreamId and is divided into a Header frame and a Data frame. After receiving the message, the server determines the endOfStream message end identifier. If the value of endOfStream of the framed message is false, it means that all frames of the message have not been completely received. Then the server continues to receive and caches the received messages in a HashMap. If the value of endOfStream of the framed message received by the server is true, it means that all frames of a message from the client have been sent. The server identifies the frame by StreamId in the HashMap to find all other framed messages with the same StreamId, and assembles it into a complete message with all framed messages.

[0073] Since 5G messages are formatted in JSON, the server verifies the validity of the message body of each received complete message through the message manager. If it is a valid JSON string, 5G service processing continues; otherwise, the message is deemed invalid and a status code 400 is returned to the client. Each 5G online billing message is filtered to verify its validity and integrity. The message manager is used to determine whether the received message is a 5G service message. 5G online billing messages are divided into three packet types: initial packet (create), update packet (update), and release packet (release). They are identified by the URI in the HTTP / 2 message header. If the message received by the server does not fall into these three packet types, it is deemed invalid and the server responds to the client with a return code of 400, notifying the client that the requested message type is incorrect.

[0074] The present invention uses the JSON format for 5G online billing message packets, and verifies the integrity of the message packets after the server receives all framed message assemblies.

[0075] Based on any of the above embodiments, if it is determined that the message is not the last frame, then continuing to receive the framed message specifically includes:

[0076] If it is determined that not all framed messages have been received within the preset delay threshold, the client is notified to send the missing messages; otherwise, the client continues to receive framed messages.

[0077] Specifically, in the message structure, after receiving the message, the server determines the endOfStream stream message end identifier. If the value of endOfStream of the framed message is false, it means that all frames of the message have not been completely received. Then the server continues to receive and caches the received messages in the HashMap.

[0078] Furthermore, during the message reception process, network jitter, instability, or other reasons may cause incomplete message delivery. If the server discovers that a message has not been fully framed within a certain delay threshold, it must immediately notify the client to resend the remaining framed messages belonging to the message. The server adds a timed scanning thread to check the framed messages cached in the HashMap, verifying the message write time and comparing it with the delay threshold. For messages that exceed the delay threshold, the server notifies the client to resend the remaining framed messages of the message to form a complete message.

[0079] The present invention realizes the function of retransmitting framed messages by informing the client to resend the missing framed messages and assembling them into a complete message body with the framed messages already received by the server when the HTTP / 2 framed message transmission fails.

[0080] Based on any of the above embodiments, the further comprising:

[0081] After the framed message is assembled, the 5G online charging system executes the online charging rule processing and deletes the framed message from the cache in real time after the processing is completed;

[0082] The processing results are returned to the client through HTTP / 2 persistent connection.

[0083] Specifically, after the server-side message is successfully assembled, it is handed over to the service processing unit module of the 5G online billing system to execute rules such as service back-calculation, accumulated usage, and fee deduction. After the message is successfully processed, the server deletes the message from the cache in real time, freeing up memory space, reducing the impact of storage on the server program, and improving processing performance.

[0084] After the 5G online billing system completes service processing, the server returns service messages such as quota information and usage reports to the network element client via a persistent HTTP / 2 connection. The HTTP / 2 protocol requires that the same message request and response must be sent over the same connection channel. When the server returns a message to the client, it must match the message. The server uses the connection channel manager to find the transmission channel for the message in the connection pool and use that channel to return the message to the client.

[0085] The message manager used in the present invention provides a verification function for the validity and integrity of the message. The server determines the business processing unit that needs to be executed subsequently based on the return result of the message manager, and provides the output of multi-dimensional indicators of real-time message processing, which facilitates operation and maintenance personnel to quickly locate and solve problems.

[0086] The 5G message transmission device provided by the present invention is described below. The 5G message transmission device described below and the 5G message transmission method described above can be referenced to each other.

[0089] The present invention proposes a method for HTTP / 2 message framing assembly and framed retransmission applied to 5G communications, so that the server can quickly assemble a complete message body after receiving the framed message, immediately release the memory space occupied by the message, and complete the validity and integrity verification of the message.
