[0002] The 5th Generation Mobile Communication Technology (5G) signaling plane deep packet inspection (DPI) program requires the input of 5G core network signaling traffic.

[0035] Embodiment 1

[0036] Figure 1 A flowchart of a 5G signaling traffic deduplication method is provided for the first embodiment of the present invention. This embodiment is applicable to the case of repeatability detection of 5G signaling traffic. The method can be performed by a 5G signaling traffic deduplication device. The 5G signaling traffic deduplication device can be implemented in the form of hardware and / or software. The 5G signaling traffic deduplication device can be configured in an electronic device. Figure 1 As shown, the method includes:

[0037] S110. Obtain data packets in the 5G signaling traffic to be processed.

[0038] Among them, 5G signaling traffic may refer to the control plane signaling traffic in the core network of the 5G mobile network. The core network (CN) is an important part of the communication network, located in the center of the network, connecting different types of network nodes, such as base stations, data centers, servers, etc. Control plane signaling may refer to the information exchange method used to control and manage the communication process in the communication system. Control plane signaling may include: transmission control signaling, call establishment and release signaling, network management signaling, etc. A data packet may refer to a data unit in TCP / IP protocol communication transmission. A data packet can be understood as a message. A data packet may include: communication protocol, communication content, and address information of the sender and receiver.

[0039] Specifically, DPI obtains data packets in the 5G signaling traffic to be processed from the core network. DPI can be deployed in parallel with the actual communication network and access communication traffic, such as 5G signaling traffic, through equipment such as splitting, aggregation and shunting.

[0040] S120: Perform protocol feature recognition on the data packet to determine the target protocol feature corresponding to the data packet.

[0041] The target protocol feature may refer to all or part of the key information corresponding to the protocol in the data packet. For example, the target protocol feature may be used to characterize the transmission direction and the type of protocol used of the data packet.

[0042] Specifically, protocol feature recognition is performed on a data packet based on a pre-trained protocol feature recognition model, thereby determining a target protocol feature corresponding to the data packet based on an output of the model.

[0043] S130: Determine the target protocol data corresponding to the target protocol feature based on the preset feature transformation mode and the target protocol feature.

[0044] The preset feature conversion method may refer to a preset feature representation form conversion method. The target protocol data may refer to a target protocol feature represented in a data form.

[0045] Specifically, a hash algorithm is used to perform feature transformation on target protocol features to determine fixed-length data, namely, target protocol data.

[0046] On the basis of the above technical scheme, "determining the target protocol data corresponding to the target protocol feature based on a preset feature transformation method and the target protocol feature" may include: sorting each sub-feature in the target protocol feature based on a preset sorting method to determine the reference protocol feature corresponding to the data packet; performing feature transformation on the reference protocol feature based on a hash algorithm to determine the target hash value corresponding to the target protocol feature.

[0047] Among them, the preset sorting method may refer to a preset sub-feature arrangement order. The target protocol features composed of sub-features in different arrangement orders have different target hash values. Sub-features may refer to detailed features in a protocol. Sub-features may be used to form target protocol features. Reference protocol features may refer to protocol features arranged in a specific order. The target hash value may be understood as the target protocol data obtained by feature transformation using a hash algorithm.

[0048] Specifically, each sub-feature in the target protocol feature is sorted in reverse order to determine the reference protocol feature corresponding to the data packet, and the reference protocol feature is transformed based on the MD5 information digest algorithm to determine the target hash value corresponding to the target protocol feature.

[0049] S140. Determine the deduplication result corresponding to the 5G signaling traffic based on the target protocol data and the existing protocol data.

[0050] The existing protocol data may refer to the target protocol data generated by the non-repeated 5G signaling traffic according to the aforementioned steps. The deduplication result may be used to characterize the deduplication processing result of the 5G signaling traffic. The deduplication result may include: traffic has been deleted (i.e., traffic duplication has been deleted) and traffic has been transmitted (i.e., traffic has been transmitted without duplication).

[0051] Specifically, the target protocol data is compared with all existing protocol data. If the target protocol data is consistent with any existing protocol data, it indicates that the 5G signaling traffic is transmitted repeatedly. To avoid repeated transmission or generating XDR call records, the 5G signaling traffic can be deleted and the corresponding deduplication results can be generated. If the target protocol data is inconsistent with all existing protocol data, it indicates that the 5G signaling traffic is transmitted for the first time. The 5G signaling traffic can be transmitted, and the corresponding deduplication results can be generated, and the target protocol data can be stored and used as existing protocol data.

[0052] The technical solution of the embodiment of the present invention obtains data packets in the 5G signaling traffic to be processed; identifies the protocol features of the data packets to determine the target protocol features corresponding to the data packets; determines the target protocol data corresponding to the target protocol features based on the preset feature transformation method and the target protocol features; and determines the deduplication results corresponding to the 5G signaling traffic based on the target protocol data and the existing protocol data. Based on the target protocol data and the existing protocol data, only the key protocol information corresponding to the 5G signaling traffic is used to accurately and conveniently perform repeatability detection on the 5G signaling traffic and perform corresponding processing on the 5G signaling traffic based on the detection results, thereby obtaining accurate deduplication results, avoiding the use of the entire 5G signaling traffic for repeatability detection, and thus improving the deduplication efficiency of the 5G signaling traffic.

[0053] Embodiment 2

[0054] Figure 2 This is a flowchart of a 5G signaling traffic deduplication method provided in Embodiment 2 of the present invention. Based on the above embodiments, this embodiment describes in detail the process of determining the target protocol characteristics corresponding to the data packet. The explanations of the terms that are the same or corresponding to the above embodiments are not repeated here. Figure 2 As shown, the method includes:

[0055] S210. Obtain data packets in the 5G signaling traffic to be processed.

[0056] S220: Perform a preliminary analysis on the data packet to determine the target protocol type corresponding to the target protocol in the data packet.

[0057] The target protocol type may include, but is not limited to, Stream Control Transmission Protocol (SCTP), Packet Forwarding Control Protocol (PFCP), and an upgraded version of the General Packet Radio Service (GPRS) Tunneling Protocol (GTP v2). In the core network, the SCTP protocol is a transport layer protocol used in the 5G core network N2 interface, the PFCP protocol is an application layer protocol used in the 5G core network N4 interface, and the GTPv2 protocol is an application layer protocol used in the 5G core network N26 interface.

[0058] Specifically, DPI performs a preliminary analysis of the data packet to determine the target protocol type corresponding to the target protocol in the data packet. A data packet uses only one protocol.

[0059] S230: Perform protocol feature recognition on the data packet based on a feature recognition method corresponding to the target protocol type, and determine a target protocol feature corresponding to the data packet.

[0060] The feature recognition method may refer to a preset specific protocol feature recognition method corresponding to each target protocol type. For example, the number and specific content of sub-features recognized by different feature recognition methods are different.

[0061] Specifically, if the target protocol type is the SCTP protocol, the source IP and destination IP are identified from the IP layer, the source port, destination port, verification tag and checksum are identified from the transport layer SCTP (SCTP protocol header), and the transmission sequence number, stream identifier and sequence number are identified from the SCTP DATA, so as to use the identified sub-features to form the target protocol features.

[0062] If the target protocol type is the PFCP protocol, the source IP and destination IP are identified from the IP layer, the source port, destination port and checksum are identified from the transport layer UDP (PFCP protocol stack), and the version (Version), the type defining the message content (Message Type), the message length (Message Length) and the sequence number (Sequence Number) are identified from the application layer PFCP (PFCP protocol header), so as to use the identified sub-features to form the target protocol features.

[0063] If the target protocol type is the GTPv2 protocol, the source IP and destination IP are identified from the IP layer, the source port, destination port and checksum are identified from the transport layer UDP (GTPv2 protocol stack), and the version (Version), the type defining the message content (Message Type), the message length (Message Length) and the sequence number (Sequence Number) are identified from the application layer GTPv2 (GTPv2 protocol header), so as to use the identified sub-features to form the target protocol features.

[0064] S240: Determine the target protocol data corresponding to the target protocol feature based on the preset feature transformation mode and the target protocol feature.

[0065] S250. Determine the deduplication result corresponding to the 5G signaling traffic based on the target protocol data and the existing protocol data.

[0066] Based on the above technical solution, "determining the deduplication result corresponding to the 5G signaling traffic based on the target protocol data and the existing protocol data" may include: performing data comparison based on the target protocol data and the existing protocol data to determine the traffic status information corresponding to the 5G signaling traffic; processing the 5G signaling traffic based on the traffic status information to determine the deduplication result corresponding to the 5G signaling traffic.

[0067] Among them, the traffic status information can be used to characterize whether the currently transmitted 5G signaling traffic is repeated with the transmitted 5G signaling traffic.

[0068] Specifically, based on the aforementioned hash algorithm as an example, a data consistency comparison is performed based on the target hash value and the existing hash value, and the traffic status information corresponding to the 5G signaling traffic is determined based on the comparison result, so that the 5G signaling traffic can be processed accordingly according to the traffic status information, and the deduplication result corresponding to the 5G signaling traffic can be determined.

[0069] On the basis of the above technical solution, "determining the traffic status information corresponding to the 5G signaling traffic based on data comparison between the target protocol data and the existing protocol data" may include: if the target protocol data is the same as any existing protocol data corresponding to the target protocol type, then determining that the traffic status information corresponding to the 5G signaling traffic is a traffic duplication state; if the target protocol data is different from each existing protocol data corresponding to the target protocol type, then determining that the traffic status information corresponding to the 5G signaling traffic is a traffic separate state.

[0070] Among them, the advantage of this setting is that it can avoid comparing protocol data between different types of protocols, which may lead to inaccurate determination of traffic status information, and further improve the accuracy of 5G signaling traffic deduplication.

[0071] On the basis of the above technical solution, "processing the 5G signaling traffic based on the traffic status information and determining the deduplication result corresponding to the 5G signaling traffic" may include: if the traffic status information is a traffic duplication state, the 5G signaling traffic is deleted, and the deduplication result corresponding to the 5G signaling traffic is determined as the traffic has been deleted; if the traffic status information is a traffic separate state, the 5G signaling traffic is transmitted to the core service module to output the communication details list, and the deduplication result corresponding to the 5G signaling traffic is determined as the traffic has been transmitted.

[0072] The technical solution of the embodiment of the present invention determines the target protocol type corresponding to the target protocol in the data packet by performing preliminary analysis on the data packet; and performs protocol feature identification on the data packet based on the feature identification method corresponding to the target protocol type, so as to extract key protocol information, i.e., target protocol features, for different protocols, thereby further improving the accuracy of 5G signaling traffic deduplication.

[0073] The following is an embodiment of a 5G signaling traffic deduplication device provided in an embodiment of the present invention. The device and the 5G signaling traffic deduplication method in the above-mentioned embodiments belong to the same inventive concept. For details not described in detail in the embodiment of the 5G signaling traffic deduplication device, please refer to the embodiment of the above-mentioned 5G signaling traffic deduplication method.
