DETAILED DESCRIPTION

[0013] Example embodiments of the present disclosure provide a user subscription method of a distributed network, a user subscription device of a distributed network, a computer program product, and an electronic device, to provide a key prerequisite for implementing more reliable user service.
[0014] In an alternative embodiment, referring to Figure 1 Fig. 1 shows a schematic diagram of a data structure of each blockchain node in a blockchain network according to an example embodiment; Step S110, in response to a subscription request of a first user, generating user subscription information of the first user, and storing the user subscription information of the first user in a first subnet; a home network of the first user is the first subnet; Step S120, the user subscription information of the first user is sent to a second subnet in the distributed network to store the user subscription information of the first user through the second subnet; the second subnet is a backup network authorized by the first subnet; Step S130, the subscription storage information of the first user is uploaded to the blockchain network to complete the subscription of the first user.
[0015] Figure 1 In the method, by providing network-level user subscription information backup, the network disaster recovery capability can be enhanced; by uploading the subscription storage information of the first user to the blockchain network, the user subscription information can be traced while ensuring that the user subscription information is not excessively exposed, which can be well applied to the distributed network architecture.
[0016] It should be noted that the distributed network can include multiple subnets, and each subnet can deploy one (or multiple subnets share one) blockchain node, and these blockchain nodes can jointly form a blockchain network, such as Figure 2 The architecture diagram of the distributed network provided in the Figure 2 The number and deployment location of the subnets included in the distributed network are not limited to the case in These subnets can be core networks of specific regions or special networks of specific industries, and the present disclosure does not make specific limitations.
[0017]
[0018] The following will be specifically described for each step in Figure 1 .
[0019] In step S110, in response to the subscription request of the first user, the user subscription information of the first user is generated, and the user subscription information of the first user is stored in the first subnet; the home network of the first user is the first subnet.
[0020] Wherein, the first user can be a user who needs to open an account in the network, and when the home network of the first user is the first subnet, the first subnet can be initiated to trigger the user subscription logic and realize user subscription.
[0021] Wherein, the user subscription information defines the information details of the subscribed user, which can include but is not limited to user identity, network slice authority, rate control, communication security and other dimension information, and the present disclosure does not make specific limitations.
[0022] For example, as shown in the following JSON format user subscription information provided: { "imsi": "xxx", "slice": [{ "xxx": xxx }], "ambr": { "xxx": "xxx" }, "security": { "k": "xxx", "amf": "xxx", "opc": "xxx", "sqn": "xxx" } } Wherein, the IMSI represents an international mobile subscriber identity, which is a "digital identity card" globally uniquely identifying the user identity, and the network accurately locates the user's home place, matches the subscription rights and interests, and is the core basis for identity verification when roaming.
[0023] Wherein, the slice represents a network slice configuration, which can record the slice type and slice priority that can be used by the user, and determines whether the user can access the customized network service in a specific scenario.
[0024] Wherein, the AMBR represents an aggregated maximum bit rate, which is a rate control index of the network for the user, including "uplink rate upper limit" and "downlink rate upper limit", and can limit the network speed of the user in the scenarios such as call, download and live broadcast, and is a key to guarantee the fair allocation of network resources.
[0025] Wherein, the security is a security key set for the communication between the user and the network, which is the core guarantee to prevent data from being eavesdropped and identity from being forged, and can include fields "k", "amf", "opc" and "sqn". Among them, the field "k" and the field "opc" are the root keys pre-stored by the user and the home network, which are used to generate temporary encryption keys for calls and data transmission; the field "amf" is an authentication management domain parameter participating in the legality verification of the identity authentication process; and the field "sqn" is a sequence number, which can ensure the uniqueness of each communication authentication.
[0026] After generating the user subscription information of the first user, the first subnet can store the user subscription information of the first user in the private database of the first subnet.
[0027] In step S120, the user subscription information of the first user is sent to a second subnet in a distributed network for backup storage of the user subscription information of the first user by the second subnet; and the second subnet is a backup network authorized by the first subnet.
[0028] Optionally, the first subnet can determine one or more backup networks, i.e., the second subnet, from the multiple subnets of the distributed network according to the deployment policy information of the distributed network, which is not specifically limited in the present disclosure.
[0029] Specifically, the first subnet can send the user subscription information of the first user to the second subnet in the distributed network through a secure channel; after obtaining the user subscription information of the first user, the second subnet can store the user subscription information of the first user into the private database corresponding to the second subnet, so as to ensure that the user subscription information of the first user is not leaked.
[0030] Optionally, after storing the user subscription information of the first user, the second subnet can return a synchronization confirmation response to the first subnet, so that the first subnet knows that the user subscription information of the first user has been backed up.
[0031] The first subnet sends the user subscription information of the first user to the second subnet in the distributed network, so as to store the user subscription information of the first user through the second subnet, thereby realizing network-level backup of the user subscription information of the first user.
[0032] In step S130, the subscription storage information of the first user is uploaded to the blockchain network to complete the subscription of the first user.
[0033] Among them, the subscription storage information defines the storage address of the corresponding user subscription information. It can include but is not limited to user temporary identifier, home network anchor point, backup network redundancy, and other dimension information, which is not specifically limited in the present disclosure.
[0034] For example, as shown in the following JSON format subscription storage information provided: { "5G-GUTI": "xxxxxxxxxxxx", "homeNetwork": { "netID": "xxx", "ipEndPoint": {"ipv4Addr": "…","port": …}, }, "backupNetwork": [{ "netID": "xxx", "ipEndPoint": {"ipv4Addr": "…","port": …} }] } Wherein, the 5G-GUTI represents a 5G global unique temporary identity, which is a "temporary identity card" allocated by the network for the user, and is a "first identity certificate" for the user to initiate a service in the visited network during roaming.
[0035] Wherein, the homeNetwork represents a home network configuration of the user, containing the fields "netID" and "ipEndPoint".
[0036] Wherein, the backupNetwork represents a backup network configuration of the home network, containing the fields "netID" and "ipEndPoint". The "netID" represents a network unique identifier for quickly locating the network, and the "ipEndPoint" represents an IP address and port number.
[0037] Each subscription storage information includes, in addition to the unique identifier pointing to a specific user, the home network of the user and the backup network of the home network. Taking the subscription storage information of the first user as an example, it can contain but is not limited to: the identification information of the first user, the configuration information of the first subnet (the home network of the first user), the configuration information of the second subnet (the backup network of the home network of the first user), etc.
[0038] In order to ensure that the blockchain network can maintain traceability and anti-tampering capabilities for user subscription information that is not synchronized across the network, when uploading the subscription storage information of the first user to the blockchain network, the subscription hash value of the first user can also be uploaded.
[0039] In an optional implementation, the above uploading of the subscription storage information of the first user to the blockchain network to complete the subscription of the first user can be achieved by the following steps: determining the subscription hash value of the first user according to the user subscription information of the first user; determining the subscription storage information of the first user according to the source storage state and the backup storage state of the user subscription information of the first user; uploading the subscription hash value of the first user and the subscription storage information of the first user to the blockchain network.
[0040] Wherein, the subscription hash value of the first user is the hash value of the user subscription information of the first user.
[0041] Wherein, the source storage state refers to the storage state of the user subscription information of the first user in the home network (i.e., the first subnet). The backup storage state refers to the storage state of the user subscription information of the first user in the backup network authorized by the home network (i.e., the second subnet). For example, if it is detected that the user subscription information of the first user is stored in the first subnet and is backed up in the second subnet, the configuration information of the first subnet and the configuration information of the second subnet can be taken as the subscription storage information of the first user.
[0042] By uploading the subscription hash value of the first user and the subscription storage information of the first user to the blockchain network, tamper-proof and traceable effects can be provided in the case that the user key information is protected.
[0043] In an optional implementation, the first subnet is deployed with a corresponding blockchain node, and the uploading of the subscription hash value of the first user and the subscription storage information of the first user to the blockchain network to complete the subscription of the first user can be achieved by the following steps: uploading the subscription hash value of the first user and the subscription storage information of the first user to the blockchain network through the first subnet corresponding blockchain node to complete the subscription of the first user.
[0044] The first subnet corresponding blockchain node writes the subscription hash value of the first user and the subscription storage information of the first user into the transaction of the blockchain, and sends it to other blockchain nodes joined in the blockchain network to endorse the transaction. Based on the blockchain strategy, after a number of (such as more than half) blockchain nodes endorse the transaction, the blockchain network reaches a consensus on the block containing the transaction, and all blockchain nodes joined in the blockchain network add the corresponding block to the chain, and write the transaction into the state database to realize data synchronization.
[0045] After data synchronization, the first subnet corresponding blockchain node can return a transaction response to prompt that the first subnet has completed the user subscription.
[0046] As shown in Figure 3 , a data structure diagram of each blockchain node in the blockchain network is provided. Among them, US_Info represents the user subscription information of the first user, Hash(US_Info) represents the subscription hash value of the first user, and USDL_Info represents the subscription storage information of the first user.
[0047] As shown in Figure 4 , an interactive flowchart of user subscription is provided, which can specifically include the following steps: Step S401, the user system initiates a subscription request of a first user to a first subnet; Step S402, the first subnet generates and stores user subscription information of the first user in response to the subscription request of the first user; Step S403, the first subnet synchronizes the user subscription information of the first user to a second subnet; Step S404, the second subnet performs backup storage on the user subscription information of the first user; Step S405, the second subnet returns a synchronization confirmation response to the first subnet; At step S406, the first subnet determines a subscription hash value of the first user according to user subscription information of the first user, and writes the subscription hash value of the first user and subscription storage information of the first user into a transaction; At step S407, the first subnet uploads the transaction to a blockchain network. At step S408, the blockchain network returns a transaction response to the first subnet after reaching a consensus on the transaction. At step S409, the first subnet notifies the user system that the subscription of the first user is completed after receiving the transaction response.
[0048] Figure 4 In the steps, the first subnet is a home network of the first user, and the second subnet is a backup network authorized by the first subnet.
[0049] In the present disclosure, each subnet in the distributed network can participate in the blockchain network as a main body, and add its database network element as a blockchain node to the blockchain network. When a user accesses the network, the user system performs user subscription in the home network: the home network saves user subscription information containing important information in the private database of the home network and a few additional authorized backup networks, and includes a hash value of the user subscription information in a transaction. After the standard process of the blockchain network, the hash value is written to each node on the blockchain, which can provide tamper-proof and traceable effects in the case of protecting the user's key information.
[0050] In an optional implementation, the following steps can also be performed: in response to a non-access stratum registration request of a second user, if the first subnet stores user subscription information of the second user, obtaining the user subscription information of the second user; authenticating the second user according to the user subscription information of the second user; and if the second user is authenticated, performing non-access stratum registration for the second user.
[0051] The non-access stratum (NAS) registration request is used to trigger user non-access stratum registration, so that the user can use network services. The request message can contain a unique identifier (such as 5G-GUTI) of the corresponding user.
[0052] When the home network of the second user or the backup network authorized by the home network of the second user is the first subnet, the first subnet stores the user subscription information of the second user. At this time, the first subnet can obtain the stored user subscription information of the second user in response to a non-access stratum registration request of the second user. After obtaining the user subscription information of the second user, the information can be used to authenticate the second user to verify the legality of the second user. If the second user is authenticated, the second user can be registered for non-access stratum.
[0053] Through the above steps, the non-access layer registration of the user affiliated to the home location or the user affiliated to the backup network of the home location can be implemented.
[0054] In an optional implementation, the following steps can also be performed: in response to the non-access layer registration request of the third user, if the first subnet does not store the user subscription information of the third user, querying the subscription storage information corresponding to the third user from the blockchain network; obtaining the user subscription information of the third user according to the subscription storage information corresponding to the third user; authenticating the third user according to the user subscription information of the third user; and if the third user is authenticated, performing the non-access layer registration of the third user.
[0055] The non-access layer (NAS) registration request is used to trigger the non-access layer registration of the user, so that the user can use the network service. The request message can include but is not limited to the unique identifier (for example, 5G-GUTI) of the corresponding user.
[0056] When the first subnet is the visiting network of the third user, in response to the non-access layer registration request of the third user, if the first subnet does not store the user subscription information of the third user, the subscription storage information corresponding to the third user can be queried from the blockchain network according to the user identifier information of the third user.
[0057] The subscription storage information corresponding to the third user can include but is not limited to the identifier information of the third user, the configuration information of the third subnet (i.e., the home network of the third user), the configuration information of the fourth subnet (i.e., the backup network of the home network of the third user), and the like.
[0058] By querying the subscription storage information corresponding to the third user, the user subscription information of the third user is obtained according to the subscription storage information corresponding to the third user, so as to implement the non-access layer registration of the roaming user.
[0059] In an optional implementation, the first subnet is deployed with a corresponding blockchain node, and the above-mentioned querying of the subscription storage information corresponding to the third user from the blockchain network can be implemented through the following steps: querying the subscription storage information corresponding to the third user from the blockchain node corresponding to the first subnet according to the user identifier information of the third user.
[0060] When the subnet of the distributed network adds its own database network element as a blockchain node to the blockchain network, there is a corresponding relationship between the subnet and the blockchain node, and the first subnet obtains the subscription storage information corresponding to the third user by querying the blockchain node corresponding to itself, which is simple and easy to implement.
[0061] In an optional implementation, the obtaining of the user subscription information of the third user according to the subscription storage information corresponding to the third user can be implemented by the following steps: determining a third subnet from the distributed network according to the subscription storage information corresponding to the third user; the third subnet is a home network of the third user; and obtaining the user subscription information corresponding to the third user from the third subnet.
[0062] According to the subscription storage information corresponding to the third user, the home network of the third user, i.e., the third subnet, is determined, so as to obtain the user subscription information of the third user from the home network of the third user preferentially.
[0063] In an optional implementation, the following steps can also be performed: if the third subnet is abnormal, determining a fourth subnet from the distributed network according to the subscription storage information corresponding to the third user; the fourth subnet is a backup network authorized by the third subnet; and obtaining the user subscription information corresponding to the third user from the fourth subnet.
[0064] For example, if the third subnet is abnormal, such as network link interruption, UDM (Unified Data Management) network element abnormality, etc. According to the subscription storage information corresponding to the third user, the backup network authorized by the third subnet, i.e., the fourth subnet, is determined from the distributed network, so as to obtain the user subscription information corresponding to the third user from the fourth subnet, which can ensure the reliability of the service provided for the user.
[0065] If there are multiple authorized backup networks of the third subnet, any backup network can be selected to obtain the user subscription information corresponding to the third user, which is not limited in the present disclosure.
[0066] In an optional implementation, the following steps can also be performed: if the user subscription information corresponding to the third user is obtained from the fourth subnet, uploading the authentication record of the third user to the blockchain network.
[0067] The obtaining of the user subscription information corresponding to the third user from the fourth subnet indicates that the home network of the third user, i.e., the third subnet, can be abnormal, and the authentication record is uploaded to the blockchain network, so as to facilitate network abnormality positioning, management and maintenance.
[0068] In an optional implementation, before the third user is authenticated according to the user subscription information of the third user, the following steps can also be performed: querying the subscription hash value corresponding to the third user from the blockchain network; and performing integrity verification on the user subscription information of the third user according to the subscription hash value corresponding to the third user.
[0069] According to the user identification information of the third user, the blockchain node corresponding to the first subnet is queried for the signing hash value corresponding to the third user, so that the user signing information of the third user obtained from the third subnet or the fourth subnet is subjected to integrity verification according to the signing hash value corresponding to the third user, so as to prevent data tampering and further ensure the accuracy of the authentication result.
[0070] It should be noted that, in actual application, in order to simplify the processing, the signing hash value corresponding to the third user and the signing storage information can be simultaneously queried from the blockchain node corresponding to the first subnet according to the user identification information of the third user, and the present disclosure does not make specific limitation thereto.
[0071] Exemplarily, as shown in Figure 5 , a roaming user authentication interaction flowchart is provided, which can specifically include the following steps: Step S501, the third user initiates a non-access layer registration request of the third user to the first subnet; Step S502, the first subnet responds to the non-access layer registration request of the third user, and queries the signing storage information corresponding to the third user from the blockchain network; Step S503, the blockchain network returns the signing storage information corresponding to the third user to the first subnet; Step S504, according to the signing storage information corresponding to the third user, the third subnet is determined from the distributed network, so as to complete the authentication of the third user by interacting with the third subnet; wherein the third subnet is the home network of the third user; the user signing information corresponding to the third user is obtained from the third subnet; Step S505, if the interaction with the third subnet is timed out, the fourth subnet can be determined from the distributed network according to the signing storage information corresponding to the third user, so as to complete the authentication of the third user by interacting with the fourth subnet; wherein the fourth subnet is the backup network authorized by the third subnet; Step S506, if the authentication of the third user is completed by interacting with the fourth subnet, the current authentication record of the third user is uploaded to the blockchain network.
[0072] Under the distributed network architecture, when the third user accesses the visited network (the first subnet), the visited network (the first subnet) queries the signing storage information thereof through the blockchain, locates the storage position of the user signing information of the third user, so as to complete the authentication of the third user, which can realize the acquisition of the user signing information while avoiding the excessive exposure of the user signing information.
