Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The terms "comprises" and "comprising," and any variations thereof, in the description and claims of this invention, are intended to cover non-exclusive inclusions, e.g., a process or an apparatus that comprises a list of steps is not necessarily limited to those structures or steps expressly listed but may include other steps or structures not expressly listed or inherent to such process or apparatus.
Fig. 1 is a flowchart of a method for a 5G user terminal to access a 5G network according to an embodiment of the present application, where as shown in fig. 1, the method includes:
and step 101, accessing the 5G user terminal equipment to the block chain through the wifi network.
The 5G user terminal device referred to in this embodiment may be exemplarily understood as a 5G device without a SIM card, such as a 5G handset without a SIM card, but is not limited to a 5G handset.
The blockchain referred to in this embodiment is a blockchain maintained by multiple operators, a temporary identity registration server of each operator accesses the blockchain and records and maintains the latest public keys of all the operators in the blockchain, 5GUE or other terminal devices may be accessed into the blockchain as nodes of the blockchain, and the blockchain may be used to record registration information of each node in the blockchain and transaction information between each node.
For example, fig. 2 is a schematic structural diagram of a communication system provided in an embodiment of the present application, and in the system shown in fig. 2, a device UE may be understood as a 5G user terminal device in the embodiment. Each operator is connected to the blockchain as a blockchain node. The temporary identity registration server and the User plane network element function Unit (UPF) of the operator access to the blockchain, the temporary identity registration server records and maintains public keys of the operators, 5G UEs with SIM cards or 5G UEs without SIM cards can both be connected to the blockchain through wifi, and the 5G UEs with SIM cards or the 5G UEs without SIM cards have unique identity identifiers (such as mobile phone numbers) on the blockchain.
After 5G UE is started, searching available 5G operator networks, detecting whether an SIM card is installed in the local machine, if the SIM card is not detected, inputting a first prompting message to a user to inquire whether the SIM card is used for accessing the 5G network in a temporary identity, if the user selects to access the 5G network in the temporary identity, prompting the user to connect wifi, connecting the wifi to a block chain through the wifi, and simultaneously displaying the searched 5G operator networks to the user in a list form so that the user selects the 5G network of the operator to be accessed from the list.
Still taking fig. 2 as an example, after the user selects the operator to access, whose 5G user terminal device has connected to the blockchain through the wifi network, the 5G user terminal device carries a pre-generated public key of the temporary identity in a registration application and sends the registration application to a 5G base station gNB of an operator network to which a user is accessed, the gNB sends the registration application to a Mobility Management Function (AMF), the AMF detects that the registration application does not carry a user hidden Identifier (SUCI) (the SUCI cannot be generated because the 5G user terminal device does not have a SIM card), and then does not initiate an authentication application to a unified data Management Unit (UDM), but notifies a Session Management Function (SMF), allocates a first IP address to the 5G subscriber terminal device, and sending the second IP address of the temporary identity registration server to the 5G user terminal equipment. And the gNB forwards the registration application to the temporary registration server.
It is understood that this is by way of illustration and not by way of limitation. For example, in some embodiments, the registration application may further include an International Mobile Equipment Identity (IMEI) number of the 5G user terminal device, or to prevent the IMEI number from being leaked, a hash value of the public key of the Temporary Identity of the 5G user terminal device and the IMEI number may be calculated, and the calculated hash value is carried in the registration application as a Globally Unique Temporary UE Identity (GUTI).
For example, in some scenarios, the first message may include not only the public key of the temporary identity of the 5G ue, but also the IMEI or GUTI of the 5G ue.
The information in the first message can be signed by a private key of the temporary identity of the 5G user terminal equipment and then broadcast to the temporary identity registration server. After receiving the first message, the temporary identity registration server firstly verifies the digital signature in the first message by using the public key in the registration application, and if the verification is passed, further compares the public key in the registration application with the public key in the first message, or when the public key in the registration application and the first message comprise the IMEI or GUTI of the 5G user terminal equipment, compares the IMEI or GUTI in the registration application with the IMEI or GUTI in the first message.
And step 104, the 5G user terminal device establishes connection with the temporary identity registration server based on the second IP address, so that the temporary identity registration server registers for the 5G user terminal device when the public key in the registration application is consistent with the public key in the first message.
Illustratively, after the SMF allocates the first IP address to the 5G user terminal device, the default gateway address is the address of the UPF, and the 5G user terminal device starts a browser to access the second IP address, thereby establishing a connection with the temporary identity registration server. Meanwhile, when the public key in the registration application is consistent with the public key in the first message, the temporary identity registration server registers for the 5G user terminal equipment, and the 5G user terminal equipment performs service formulation and online payment by means of the temporary identity registration server. And meanwhile, recording the registration information, the payment information and the service information of the 5G user terminal equipment on a block chain account book. The data interaction between the 5G user terminal equipment and the temporary identity registration server in the processes of registration, business formulation, online payment and the like is signed by adopting a private key of the 5G user terminal equipment, or a session key can be generated according to the private key and a public key of the 5G user terminal equipment for confidentiality to carry out encryption communication.
After the 5G user terminal equipment finishes payment, the temporary identity registration server adds the temporary identity, the access authority and the time limit of the 5G user terminal equipment in the UDM.
And 105, the 5G user terminal equipment accesses the 5G network of the operator after the registration is finished.
In this embodiment, the 5G user terminal device accesses the blockchain through the wifi network, and carries the public key of its own temporary identity in the registration application after accessing the blockchain to send to the 5G base station of the operator, the 5G base station forwards the registration application to the temporary identity registration server in the blockchain, and notifies the SMF to allocate the first IP address for the 5G user terminal device, and pushes the second IP address of the temporary identity registration server to the 5G user terminal device, and at the same time, the 5G user terminal device also carries the public key of its own temporary identity in the first message to send to the temporary identity registration server, and establishes connection with the temporary identity registration server according to the second IP address of the temporary identity registration server, so that the temporary identity registration server registers for the 5G user terminal device after comparing the public key in the registration application to be consistent with the public key in the first message, and the 5G user terminal equipment can access the 5G network after the registration is finished. The scheme provided by the embodiment can allow the user without the SIM card to safely access the 5G network and use part of services of the 5G network.
