Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a signaling interface association method, apparatus, computer equipment, computer-readable storage medium, and computer program product. Background Art

[0002] Signaling interfaces are used to control and manage the interaction between communication devices or systems. They do not transmit user data, but are used to control and manage sessions, mobility, security, resource allocation, and various network functions. Signaling interface association is an important means to achieve security assurance, efficient operation, and intelligent services. Through interface signaling association, operators can better ensure network security, manage network resources, improve user service quality, and develop new business opportunities.

[0003] In the related technology, IMSI (International Mobile Subscriber Identity), MSISDN (Mobile Station International Subscriber Directory Number) and IMEI (International Mobile Equipment Identity) in the user identifier are mainly used as association keys for signaling interface association.

[0004] However, when a signaling interface message does not carry IMSI, MSISDN or IMEI, the signaling interface is difficult to associate. Therefore, the signaling interface association method in the related technology is limited to specific signaling interfaces or in specific scenarios, and has poor applicability, resulting in poor signaling interface association effect. Summary of the invention

[0005] Based on this, it is necessary to provide a signaling interface association method, device, computer equipment, computer readable storage medium and computer program product that can realize multi-signaling interface association and improve the signaling interface association effect in response to the above technical problems.

[0006] In a first aspect, the present application provides a signaling interface association method, the method comprising:

[0007] Receiving a signaling message from a target interface, and parsing the signaling message to obtain a parsing result, wherein the parsing result includes user identification information;

[0008] If a corresponding global user node is found in the global user table according to the user identification information, the index list of the global user node is updated according to the user identification information, and the context information of the global user node is updated according to the parsing result.

[0009] By adopting the signaling interface association method provided in the embodiment of the present application, by creating a global user node and an index list of the global user node, it is possible to realize the association between multiple signaling interfaces based on multiple user identification information, which can not only improve the signaling interface association effect, but also improve the universality of the signaling interface association method.

[0010] In one embodiment, the method further comprises:

[0083] In one embodiment, as shown in FIG1 , a signaling interface association method is provided. This embodiment is illustrated by applying the method to a terminal. It can be understood that the method can also be applied to a core network, and can also be applied to a system including a terminal and a core network, and is implemented through the interaction between the terminal and the core network. In this embodiment, the method includes the following steps 102 to 104, wherein:

[0084] Step 102: Receive a signaling message from the target interface, and parse the signaling message to obtain a parsing result, wherein the parsing result includes user identification information.

[0085] In the embodiment of the present application, the target interface is the interface to be associated. Exemplarily, in the 5G registration process scenario, the target interface may include the N1 interface, the N2 interface, the N13 interface, and the N8 interface, or in the 4G / 5G switching process scenario, the target interface may include the S1-MME interface, the 4G-NAS interface, the S11 interface, and the N2 interface.

[0086] After receiving the signaling message from the target interface, the signaling message can be parsed to obtain user identification information from the signaling message. The user identification information may include but is not limited to the following information: IMSI / SUPI identification, IMEI / PEI identification, MSISDN / GPSI identification, GUTI / 5G-GUTI identification, MME-UE-S1AP / AMF-UE-NGAP identification, terminal PDN / PDU IP address identification, authentication RES hash value identification, switching source to destination code stream hash value identification, switching destination to source code stream hash value identification, SUCI hash value identification, S1-U-SGW / N3-UPF FTEID identification and other user identifications.

[0087] Step 104: if a corresponding global user node is found in the global user table according to the user identification information, the index list of the global user node is updated according to the user identification information, and the context information of the global user node is updated according to the parsing result.

[0088] In the embodiment of the present application, after the user identification information is parsed, the corresponding global user node can be searched in the global user table based on the user identification information. The global user table is used to record the created global user nodes, the global user nodes are used to store user context information, and the global user nodes have corresponding index lists, which are used to record the user identification information that can index the global user nodes.

[0089] In the case where the index list of the global user node includes the currently parsed user identification information, the global user node corresponding to the index list can be used as the found global user node, and the index list is updated based on the user identification information, and the context information of the global user node is updated according to the parsing result. For example, if the context information of the global user node includes the user identification context, the user identification information is saved in the user identification context of the global user node.

[0090] The above-mentioned signaling interface association method receives a signaling message from a target interface, and parses the signaling message to obtain a parsing result, wherein the parsing result includes user identification information. If a corresponding global user node is found in a global user table according to the user identification information, an index list of the global user node is updated according to the user identification information, and context information of the global user node is updated according to the parsing result. By adopting the signaling interface association method provided by the embodiment of the present application, by creating a global user node and an index list of the global user node, association between multiple signaling interfaces can be achieved based on multiple user identification information, which can not only improve the signaling interface association effect, but also improve the universality of the signaling interface association method.

[0091] In an exemplary embodiment, the parsing result may also include at least one of the following information: mobility information, session information, and security information; the context information may include at least one of the following information: user identification context, mobility context, session context, and security context.

[0092] In the embodiment of the present application, after parsing the signaling message of the target interface, the obtained parsing result may include user identification information, mobility information, session information and security information, and the corresponding context information of the global user node may include user identification context, mobility context, session context and security context. That is, when the parsing result includes user identification information, the user identification information may be stored in the user identification context of the global user node; when the parsing result includes mobility information, the user identification information may be stored in the mobility context of the global user node; when the parsing result includes session information, the session information may be stored in the session context of the global user node; when the parsing result includes security information, the security information may be stored in the security context of the global user node.

[0093] By adopting the signaling interface association method provided in the embodiment of the present application, fragmented contexts can be integrated through the global user node, thereby improving the signaling interface association effect.

[0094] In an exemplary embodiment, the above method may further include:

[0095] If no corresponding global user node is found in the global user table according to the user identification information, a global user node is created, the user identification information is written as index information into the index list of the global user node, and the context information of the global user node is updated according to the parsing result.

[0096] In an embodiment of the present application, if the corresponding global user node has not yet been created, the corresponding global user node cannot be found in the global user table based on the user identification information. At this time, the corresponding global user node can be created, and the user identification information can be written as index information into the index list of the global user node, and the context information of the global user node can be updated according to the parsing result.

[0097] Exemplarily, if after parsing the signaling message of the signaling interface 1, the corresponding global user node 1 is not found based on the user identification information obtained by parsing, then the global user node 1 can be created, the user identification information obtained by parsing is added to the index list corresponding to the global user node 1, and the user identification information, mobility information, session information, and security information obtained by parsing are added to the user identification context, mobility context, session context, and security context of the global user node 1. After subsequently parsing the signaling message of the signaling interface 2, the global user table can be searched based on the user identification information obtained by parsing. If the global user node 1 is found, the index list of the global user node 1 can be updated based on the user identification information obtained by parsing, and the user identification information, mobility information, session information, and security information obtained by parsing are added to the user identification context, mobility context, session context, and security context of the global user node 1, thereby realizing the association between the signaling interface 1 and the signaling interface 2 based on the global user node 1.

[0098] In an exemplary embodiment, the user identification information includes first user identification information, the first user identification information is information indexed to a global user node, and updating the index list of the global user node according to the user identification information includes:

[0099] If the user identification information includes second user identification information in addition to the first user identification information, the second user identification information is used as index information and added to the index list of the global user node.

[0100] In an embodiment of the present application, when the index list of a global user node is updated based on user identification information, user identification information not stored in the index list may be added to the global user node to implement an update of the index list of the global user node.

[0101] Exemplarily, after parsing the signaling message of signaling interface 2, user identification information 1 and user identification information 2 are obtained, and then a search is performed in the global user table based on user identification information 1 and user identification information 2. If global user node 1 is found, the user identification information 2 currently parsed can be added to the index list of the global user node 1.

[0102] By adopting the signaling interface association method provided in the embodiment of the present application, a global user node and an index list of the global user node can be created. Then, when associating multiple signaling interfaces, multiple user identification information can be added to the index list, and then the association between multiple signaling interfaces can be achieved based on the multiple user identification information and the global user node. This can not only improve the signaling interface association effect, but also improve the universality of the signaling interface association method.

[0103] In an exemplary embodiment, as shown in FIG. 2 , if the corresponding global user node is not found in the global user table according to the user identification information, creating a global user node may include steps 202 to 204, wherein:

[0104] Step 202, if no corresponding global user node is found in the global user table according to the user identification information, then determine whether the user identification information is of a specified type;

[0105] Step 204: When the user identification information is of a specified type, create a global user node.

[0106] In an embodiment of the present application, if the corresponding global user node is not found in the global user table according to the user identification information, it is determined whether the user identification information is a pre-set specified type, for example: a type list is pre-set, and only the identification types added to the list can trigger the creation of a global user node, such as adding IMSI and SUPI to the type list in advance, then when the user identification information is the IMSI or SUPI, a global user node can be created.

[0107] In this way, the signaling interface association method provided in the embodiment of the present application can avoid the creation of global user nodes with dynamic user identification information or user identification information that cannot clearly identify the user's true identity, which causes problems such as aging and failure of global user nodes and inability to locate the user's true identity. The creation of global user nodes is triggered by user identification information with good correlation, which can improve the association effect and efficiency.

[0108] In an exemplary embodiment, as shown in FIG. 3 , the method may further include steps 302 to 304, wherein:

[0109] In step 302, if the user identification information is not of the specified type, the user identification information is added to the context of the target interface;

[0110] In step 304, when there is a global user node update or a new global user node is created, the corresponding global user node is searched based on the context of the target interface, and when the corresponding global user node is found, the index list and context information of the global user node are updated based on the context of the target interface.

[0111] In an embodiment of the present application, if the corresponding global user node is not found in the global user table according to the user identification information, it can be determined whether the user identification information is a preset type of user identification information. If so, a global user node is created, and the user identification information is written as index information into the index list of the global user node, and the context information of the global user node is updated according to the parsing result; otherwise, the current parsing result can be saved in the context of the target interface, and after parsing the signaling message of other signaling interfaces, if a new global user node is created or the global user node update is triggered, it can be searched in the global user table based on the user identification information. If the global user node is indexed, the global user node can be updated according to the user identification information, including updating the index list and context information of the global user node.

[0112] In an exemplary embodiment, if for the same user, a global user node 1 is created based on user identification information 1, and a global user node 2 is created based on user identification information 2, then when the user identification information 3 is simultaneously indexed to multiple global user nodes, the multiple global user nodes can be merged, that is, the index lists corresponding to the multiple global user nodes can be merged, the user identification contexts of the multiple global user nodes can be merged, the session contexts can be merged, the mobile contexts can be merged, and the security contexts can be merged.

[0113] By adopting the signaling interface association method provided in the embodiment of the present application, a specified type of user identification information can be used to trigger the creation of a global user node, and the parsing results corresponding to user identification information of a non-specified type can be saved in the context of the target interface. The signaling interface association can be subsequently re-performed based on the context of the target interface, so that the global user node can be associated with multiple types of user identification information, which can not only improve the signaling interface association effect, but also improve the universality of the signaling interface association method.

[0114] In order to enable those skilled in the art to better understand the association process of multiple signaling interfaces, the embodiments of the present application are described below using two examples.

[0115] In Example 1, it involves processing multiple signaling interface associations for a 5G registration process, and the signaling interface association method in the embodiment includes the following steps a1 to a7.

[0116] In step a1, the N1 interface Registration Request message carried in the Initial UE Message of the N2 interface is parsed, and the 5GS mobile identity SUCI is saved. Due to the initial access, the global user node cannot be queried in the global user table through the SUCI hash value identifier.

[0117] In step a2, the NUDM-UEAU (Network User Data Management - UserEquipment Authentication) service message of the N13 interface is parsed to obtain the identity information IMSI, security information KAUSF and XRESSTAR, and the global user node 1 is created in the global user table using the IMSI identifier. The IMSI / SUPI identifier (IMSI) and the authentication RES hash value identifier (XRESSTAR) are added to the index list of the global user node 1, and the IMSI / SUPI identifier and the authentication RES hash value identifier are saved in the user identification context of the global user node 1, and KAUSF is saved in the security context of the global user node 1, as shown in Figure 4a.

[0118] In step a3, the N1 interface Authentication Response message carried in the Uplink NAS Transport message of the N2 interface is parsed, and the global user node 1 can be queried in the global user table using the authentication RES hash value identifier generated by the RES field carried by the message, and the MME-UE-S1AP / AMF-UE-NGAP identifier carried by the message and the SUCI hash value identifier obtained in the previous step 401 (the SUCI hash value identifier is associated with the MME-UE-S1AP / AMF-UE-NGAP through the association operation within the N2 interface, and the subsequent association operation within the interface will not be explained) are added to the index list of the global user node 1 respectively, and the MME-UE-S1AP / AMF-UE-NGAP identifier and the SUCI hash value identifier are saved in the user identifier context of the global user node 1, completing the signaling association of N1, N2 and N13, as shown in Figure 4b.

[0119] In step a4, the N1 interface Security Mode Command message carried in the Downlink NAS Transport message of the N2 interface is parsed, and the NAS encryption algorithm type carried is saved in the security context of the global user node 1, as shown in FIG. 4c;

[0120] In step a5, the N1 interface NAS message carried in the Uplink NAS Transport message of the N2 interface is parsed. First, the NAS decryption root key KNASenc of the AMF can be derived through the KAUSF and NAS encryption algorithm type of the terminal user stored in the global user node 1. Then, the NAS message can be decrypted into the Security Mode Command in combination with the uplink Sequence number of the NAS message. The IMEI / PEI identifier (IMEI) carried by it is indexed to the global user node 1, and the IMEI / PEI identifier is saved in the user identifier context of the global user node 1, as shown in Figure 4d;

[0121] In step a6, the NUDM-SDM (Network Data Management Function -Subscription Data Management) service message of the N8 interface is parsed, and the IMSI identifier carried by the message can be queried in the global user table to find the global user node 1, and the MSISDN / GPSI identifier (MSISDN) is added to the index list of the global user node 1, and the MSISDN / GPSI identifier is saved in the user identifier context of the global user node 1, completing the signaling association of N1, N2, N13 and N8, as shown in Figure 4e;

[0122] In step a7, the N1 interface Registration Accept message carried in the Downlink NAS Transport message of the N2 interface is parsed. First, the AMF NAS decryption root key KNASenc can be derived through the KAUSF and NAS encryption algorithm type of the terminal user saved in the global user node 1. The NAS message can be decrypted as Registration Accept in combination with the downlink Sequence number of the NAS message. The GUTI / 5G-GUTI identifier (5G-GUTI) carried by it is indexed to the global user node 1, and the GUTI / 5G-GUTI identifier is saved in the user identification context of the global user node 1, as shown in Figure 4f.

[0123] In Example 2, in the scenario involving multi-signaling interface association for processing a 4G attachment process and a 4G / 5G switching process, the signaling interface association method in the embodiment includes the following steps b1 to b7, wherein:

[0124] In step b1, the NAS interface Attach Request message carried in the Initial UE Message message of the S1-MME interface is parsed to obtain the EPS mobile identity identifier IMSI. If the global user node is not found in the global user table through the IMSI / SUPI identifier, a global user node 2 is created, and the IMSI / SUPI identifier is added to the index list of the global user node, as shown in Figure 5a;

[0125] In step b2, the NAS interface Authentication Response message carried in the Uplink NAS Transport message of the S1-MME interface is parsed, the MME-UE-S1AP / AMF-UE-NGAP identifier carried therein is added to the index list of the global user node 1, and the MME-UE-S1AP / AMF-UE-NGAP identifier is saved in the user identifier context of the global user node 2, as shown in FIG. 5b ;

[0126] In step b3, the Create Session Request message of the S11 interface is parsed to obtain identification information such as IMSI, MSISDN, IMEI, session information such as APN (Access Point Name) and PDN (Public Data Network) type, and mobile control information such as terminal location. The global user node 2 can be queried in the global user table using the IMSI identifier it carries, and the MSISDN / GPSI identifier (MSISDN) and IMEI / PEI identifier (IMEI) it carries are added to the index list of the global user node 2 respectively, and the MSISDN / GPSI identifier and IMEI / PEI identifier are saved in the user identification context of the global user node 2, and the session information such as APN and PDN type and mobile control information such as terminal location are saved in the session context and mobile control context of the global user node 2 respectively, as shown in Figure 5c;

[0127] In step b4, the Create Session Response message of the S11 interface is parsed to obtain identification information such as the terminal PDN / PDU IP address identifier, the S1-U-SGW / N3-UPF FTEID identifier, and session information such as the PDN IP, the S1-U-SGW tunnel, and the default bearer EPS ID. Through the internal association of the interface, the PDN / PDU IP address identifier (PDN IP) and the S1-U-SGW / N3-UPF FTEID identifier (S1-U-SGW FTEID) carried by it can be added to the index list of the global user node 2 respectively, and the PDN / PDU IP address identifier and the S1-U-SGW / N3-UPF FTEID identifier are saved in the user identification context of the global user node 2, and the session information such as the PDN IP, the S1-U-SGW tunnel, and the default bearer EPS ID are saved in the session context of the global user node 2, thereby completing the signaling association of S1-MME, 4G-NAS, and S11, as shown in Figure 5d;

[0128] In step b5, the NAS interface Attach Accept message carried in the Downlink NAS Transport message of the S1-MME interface is parsed, and the GUTI / 5G-GUTI identifier (GUTI) carried by it can be added to the index list of the global user node 2 through the internal association of the interface, and the GUTI / 5G-GUTI identifier is saved in the user identifier context of the global user node 2, as shown in Figure 5e;

[0129] In step b6, the Handover Required message of the S1-MME interface is parsed, and the hash value identifier (Source to Target Transparent Container) of the transparent code stream of the switching source station to the destination station carried by the message is added to the index list of the global user node 2, and the hash value identifier of the transparent code stream of the switching source station to the destination station is saved in the user identification context of the global user node 2, as shown in Figure 5f;

[0130] In step b7, the Handover Request message of the N2 interface is parsed, and the global user node 2 can be queried in the global user table using the hash value identifier (Source to Target Transparent Container) of the transparent code stream from the switching source station to the destination station. The subsequent user node related context update is not repeated here, thus completing the signaling association of S1-MME, 4G-NAS, S11 and N2.

[0131] In the related technology, signaling traffic is input into the diverter, and the diverter will divert the signaling traffic to the signaling-related device according to specific diversion rules. Since the diverter can generally only perform simple logical distribution, such as based on IP, port or protocol, it cannot perform user-based diversion. As a result, the multi-interface signaling of the same user cannot be diverted to the same signaling-related device.

[0132] As shown in FIG6 , the signaling interface association method provided in the embodiment of the present application may not distinguish between a single signaling association device networking or multiple signaling association device scenarios, and may use the same logic to process the signaling message involving a certain user input into the signaling association device and synchronize the user's context after processing the user synchronization information message involving the user from other signaling association devices, that is, it is not limited that the multi-interface signaling of the same user must be diverted to the same signaling association device. In an exemplary embodiment, the above method may also include:

[0133] After the context information of the global user node is updated, a context synchronization instruction is sent to the target signaling association device based on the context information of the global user node, and the context synchronization instruction is used to instruct the target signaling association device to perform signaling synchronization based on the context information of the global user node.

[0134] In an embodiment of the present application, a target signaling association device that receives a context synchronization instruction can obtain context information of a global user node from the context synchronization instruction, and obtain user identification information of a user based on the user identification context in the context information, and search for a corresponding global user node based on the user identification information, and when the corresponding global user node is found, update the context information and index list of the found global user node based on the context information.

[0135] 7 , the signaling association device in the embodiment of the present application may specifically include: a signaling receiving module 701 , a signaling parsing module 702 , a user information synchronization receiving module 703 , a signaling association and user information synchronization module 704 , and a user information synchronization sending module 705 .

[0136] Among them, the signaling receiving module 701 is used to receive input signaling traffic; the signaling parsing module 702 is used to parse and process signaling traffic; the user information synchronization receiving module 703 is used to receive user synchronization information messages; the signaling association and user information synchronization module 704 is used for signaling association and processing user synchronization information, and determining whether the user context needs to be sent outward; the user information synchronization sending module 705 is used to send user synchronization information messages.

[0137] As shown in FIG8 , a multi-signaling association device network is provided in an embodiment of the present application. When the signaling traffic exceeds the processing capacity of a single signaling association device, a multi-signaling association device network can be used. Assuming that the input signaling traffic is S1-MME interface and S11 interface signaling, the diverter adopts a simple diversion rule, for example, SCTP (Stream Control Transmission Protocol) traffic is diverted to signaling association device 1, and GTP (GPRS Tunneling Protocol) traffic is diverted to signaling association device 2. On signaling association device 1, when the S1-MME signaling of a specific user triggers a change in the user's context, signaling association device 1 sends the context information of the global user node corresponding to the user to signaling association device 2 through a context synchronization instruction. Similarly, on signaling association device 2, when the S11 signaling of a specific user triggers a change in the user's context, signaling association device 2 sends the context information of the global user node corresponding to the user to signaling association device 1 through a context synchronization instruction. In this way, the user context information of the same user in the signaling association device 1 and the signaling association device 2 will be kept synchronized, so that the user context information of the same user is concentrated in the same signaling association device, which can improve the utilization rate of data.

[0138] In order to enable those skilled in the art to better understand the embodiments of the present application, the embodiments of the present application are described below through specific examples.

[0139] 9, first, extract the user identification information and mobility information, session information, security information, etc. in the signaling message, where the user identification information includes but is not limited to an IMSI / SUPI identifier, an IMEI / PEI identifier, an MSISDN / GPSI identifier, a GUTI / 5G-GUTI identifier, an MME-UE-S1AP / AMF-UE-NGAP identifier, a terminal PDN / PDU IP address identifier, an authentication RES hash value identifier, a switching source to a destination code stream hash value identifier, a switching destination to a source code stream hash value identifier, a SUCI hash value identifier, an S1-U-SGW / N3-UPF FTEID identifier, and other user identifiers;

[0140] Secondly, using the extracted user identification information, searching or creating a global user node in the global user table, the global user node is used to store user context, the user context includes but is not limited to user identification context and mobility context, session context, security context and other information;

[0141] Again, the extracted user identification information is used to update the user identification context in the global user node, where the user identification context includes but is not limited to IMSI / SUPI identification, IMEI / PEI identification, MSISDN / GPSI identification, GUTI / 5G-GUTI identification, MME-UE-S1AP / AMF-UE-NGAP identification, terminal PDN / PDU IP address identification, authentication RES hash value identification, switching source to destination code stream hash value identification, switching destination to source code stream hash value identification, SUCI hash value identification, S1-U-SGW / N3-UPF FTEID identification and other user identifications, and all user identifications in the user identification context are indexed with the user node respectively, and it is recorded whether the user identification context is updated;

[0142] Next, the extracted mobility information, session information, and security information are used to update the mobility control context, session context, and security context in the global user node, respectively, and whether the mobility control context, session context, and security context are updated is recorded respectively;

[0143] Finally, if the user identification context, mobility control context, session context or security context is updated, a user context synchronization instruction is sent.

[0144] By using the signaling interface association method provided in the embodiment of the present application, when the global user node corresponding to a terminal is created, the subsequent signaling interface involving the terminal can use multiple user identification information as index key values ​​to find the global user node corresponding to the terminal with a high probability, and complete the context update of the terminal, that is, the purpose of multi-signaling association is achieved. Compared with the one-to-one key value pair of user identification in the related technology, the success rate of multi-signaling association can be greatly improved. In addition, the method and device of the present invention can cope with both small and large traffic scenarios. In actual measurements, in addition, for scenarios where some signaling interface messages are missing, the completeness of the terminal context can also be greatly improved.
