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 101, the 5G user terminal equipment accesses the block chain based on the SIM card of the first operator network installed by the user terminal equipment.
The 5G user terminal device referred to in this embodiment is installed with the SIM card of the first operator network, but is not installed with the SIM cards of other operator networks. The 5G user terminal equipment is connected to the 2G/3G/4G/5G network of the first operator through the SIM card of the first operator network, and further connected to the block chain.
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, an operator server or other terminal devices can be accessed into the blockchain as nodes of the blockchain, and the blockchain can be used for recording registration information of each node on the blockchain and transaction information between each node.
For example, fig. 2 is a schematic structural diagram of a communication system provided in this embodiment, in the system shown in fig. 2, a device UE may be understood as a 5G user terminal device (hereinafter referred to as a 5G UE) in this embodiment, a SIM card of an operator a is installed in the 5G UE, and a block chain is accessed through a network of the operator a (i.e., a first operator network in this embodiment), and the operator a and other operators are also used as block chain nodes and connected to the block chain. In fig. 2, the 5G base station gNB, the User Plane network Function Unit (UPF), the mobility Management Function unit (AMF), the unified data Management Unit (UDM), and the Session Management Function unit (SMF) are all devices in the operator B network to which the User wants to Access, and the 5G UE does not have the SIM card of the operator B installed therein. The temporary identity registration server and a user plane network element Function Unit (UPF) of the operator B access to the blockchain, and the temporary identity registration server records and maintains public keys of operators in the blockchain.
After 5G UE is started, searching available 5G operator networks, detecting whether the SIM card is installed in the local computer, inquiring whether a user accesses the 5G networks of other operators by a temporary identity after detecting the SIM card of the operator A, meanwhile, searching other 5G operator networks by the 5G UE, and presenting the other operator networks to the user in a list form so that the user selects the operator network to be accessed from the list. The network of operator B selected by the user in the scenario shown in fig. 2 (the operator network selected by the user to be accessed is hereinafter simply referred to as the second operator network).
Still taking fig. 2 as an example, in fig. 2, the user selects to access the second operator network of the operator B, the 5G user terminal device carries the pre-generated public key of the temporary identity in the operator B in the registration application to be sent to the 5G base station gbb of the second operator network to which the user wants to access, the gbb sends the registration application to the AMF, the AMF detects that the registration application does not carry the user hidden Identifier (sui) (since the 5G user terminal device does not have the SIM card of the operator B, the SUCI in the operator B cannot be generated), and then the SMF does not initiate an authentication application to the UDM, but notifies the SMF to allocate the first IP address of the 5G user terminal device in the operator B to the 5G user terminal device, and sends the second IP address of the temporary identity registration server to the 5G user terminal device. Meanwhile, the gNB forwards the registration application to the temporary registration server, and forwards the public key of the temporary registration server to the 5G user terminal equipment.
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 block chain, so that the temporary identity registration server in the block chain receives the first message.
After receiving the first message, the temporary identity registration server verifies the digital signature in the first message by using the public key of the temporary identity of the 5G user terminal equipment carried in the registration application, if the verification is passed, the public key in the registration application is further compared with the public key in the first message, and even when the registration application and the first message comprise the IMEI and/or the GUTI of the 5G user terminal equipment, the IMEI and/or the GUTI in the registration application is also compared with the IMEI and/or the 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 when the public key in the registration application of the temporary identity registration server is consistent with the public key in the first message, temporary identity registration is performed for the 5G user terminal device in the second operator network.
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. And meanwhile, when the temporary identity registration server verifies that the public key in the registration application is consistent with the public key in the first message, registering the 5G user terminal equipment in the second operator network, and making a service and paying on line by the 5G user terminal equipment by means of the temporary identity registration server. And the temporary identity registration server records the registration information, the payment information and the service information of the 5G user terminal equipment on the block chain account book.
In this embodiment, data interaction between the 5G user terminal device and the temporary identity registration server during registration, service formulation, online payment and the like is signed by using a private key of the 5G user terminal device, or for confidentiality, a session key may be generated according to the private key and a public key of the 5G user terminal device to perform encryption communication.
Further, after the 5G user terminal device finishes payment, the temporary identity registration server adds the temporary identity, the access right and the time limit of the 5G user terminal device in the UDM.
It should be noted here that in this embodiment, the 5G ue includes two IP addresses, where one of the two IP addresses is an IP address of the 5G ue in the first operator network, and is assumed to be Ipa; the other is the IP address of the 5G subscriber terminal device in the second carrier network, which is assigned by the SMF to the 5G subscriber terminal device, which is assumed to be Ipb. Wherein, before the registration is successful, the 5G user terminal equipment uses Ipa except accessing the temporary identity registration server. After successful registration, the 5G subscriber terminal device may use either of Ipa and Ipb, for example, in one scenario, considering that the 5G subscriber terminal device is installed with a SIM card of the first operator, Ipa may be set to a high usage priority and Ipb may be set to a low usage priority.
And 105, the 5G user terminal device accesses the 5G network of the second operator after the registration is completed.
In this embodiment, the 5G user terminal device accesses the block chain through the SIM card of the first operator network installed by itself, and carries the public key of the temporary identity in the second operator network after accessing the block chain in the registration application, and sends the public key to the 5G base station of the second operator network to which the user wants to access, the 5G base station forwards the registration application to the temporary identity registration server in the block chain, 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, meanwhile, the 5G user terminal device also carries the public key of the temporary identity in the first message through the SIM card of the first operator network installed by itself, sends the first IP address 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, after the public key in the registration application is compared with the public key in the first message, the temporary identity registration server performs temporary identity registration for the 5G user terminal equipment in the second operator network, and then the 5G user terminal equipment can access the 5G network after the registration is completed.
