Detailed Description
The following describes specific embodiments of the present invention in detail with reference to the drawings. It should be understood that the detailed description and specific examples, while indicating and illustrating the invention, are not intended to limit the invention.
The fifth generation mobile communication network (5th generation mobile networks,5G) base stations are divided into macro base stations and micro base stations, wherein the macro base stations are mainly used for outdoor coverage, and the micro base stations are mainly used for indoor scenes.
However, currently, if there are users of multiple operators in the same indoor area, for example, there are users of multiple operators in the same home, and the users of multiple operators all need network services. Then, the micro base stations belonging to different operators need to be deployed in the indoor area, namely the micro base stations need to be deployed repeatedly, which causes resource waste and poor user experience.
In order to solve the above problems, the embodiment of the invention provides a terminal access method based on a blockchain network. The block chain network is a alliance block chain network, the creator node is a different operator, and the creation block of the block chain network comprises the operator identity information and the operator public key of the different operator. When the block chain network is constructed, different operators sign the micro base station information list of the subordinate micro base station by using the private key of the operators, the signed micro base station information list is broadcast to the block chain network, and the accounting node of the block chain network stores the micro base station information list broadcast by the different operators into the block chain account book of the block chain network. The micro base station information list comprises micro base station identifiers, micro base station public keys and other information corresponding to the micro base stations of different operators. After the block chain network is constructed, the block chain network comprises a plurality of micro base stations belonging to different operators, namely, the micro base stations belonging to different operators are connected into a unified block chain network, and the different micro base stations can be communicated with each other based on the block chain network.
In addition, each micro base station has a macro base station arranged corresponding to the operator to which the micro base station belongs and is in signal connection with the macro base station. The micro base station is also connected to a network of a certain area, such as a home network, and is simultaneously signal-connected to a user terminal (e.g., a mobile phone) in the certain area network.
As a first aspect of the present invention, an embodiment of the present invention provides a terminal access method based on a blockchain network, where the method is applied to the foregoing micro base station, as shown in fig. 1, and the method includes the following steps:
step S101, responding to the first authentication registration request information of the user terminal, and generating and sending second authentication registration request information to the affiliated macro base station.
The user terminal may be a mobile terminal, such as a 5G mobile phone terminal. The second authentication registration request information includes a user identifier corresponding to the user terminal.
In one embodiment, the micro base station receives first authentication registration request information sent by a user terminal in a network area (such as a home network area); the first authentication registration request information includes, but is not limited to: the terminal identification of the user terminal, the user identification (such as a mobile phone number) corresponding to the user terminal and the authentication information corresponding to the user identification. The micro base station responds to the first authentication registration request information, and writes the micro base station identification of the micro base station in the first authentication registration request information to generate second authentication registration request information, namely the second authentication registration request information comprises the terminal identification of the user terminal, the user identification corresponding to the user terminal and the authentication information corresponding to the user identification, and also comprises the micro base station identification of the micro base station. And then, the micro base station sends the generated second authentication registration request information to the macro base station to which the micro base station belongs.
After receiving the second authentication registration request information sent by the micro base station to which the macro base station belongs, responding to the second authentication registration request information, and forwarding the second authentication registration request information to the core network to which the macro base station belongs, so that the core network to which the macro base station belongs can identify whether the user identifier contained in the second authentication registration request information belongs to the registered user identifier of the operator to which the macro base station belongs, namely, whether the user identifier is the user of the operator to which the core network belongs or not based on the second authentication registration request information. If the core network to which the macro base station belongs recognizes that the user identifier is a registered user identifier belonging to an operator to which the macro base station belongs, that is, the user identifier and the macro base station belong to the same operator, the core network performs authentication according to a current authentication flow and based on authentication information corresponding to the user identifier contained in the second authentication registration request information, and returns an obtained direct authentication result message to a subordinate micro base station through the macro base station, so that the subordinate micro base station determines whether to provide network access service for the user terminal based on the direct authentication result message. If the core network to which the macro base station belongs recognizes that the user identifier is not the registered user identifier of the operator to which the macro base station belongs, namely, the user identifier and the macro base station belong to different operators, the core network generates and sends user attribution abnormal information to the macro base station, and after the macro base station receives the user attribution abnormal information, the user attribution abnormal information is forwarded to the micro base station corresponding to the subordinate. The user attribution abnormal information comprises information that the user identification and the macro base station belong to different operators.
Step S102, receiving abnormal information of the user attribution returned by the affiliated macro base station in response to the second authentication registration request information.
The user attribution abnormal information comprises a terminal identifier, a user identifier corresponding to the terminal identifier and information that the user identifier and the macro base station belong to different operators.
Step S103, responding to the abnormal information of the user attribution, generating and broadcasting third authentication registration request information to the block chain network.
The third authentication registration request information comprises a user identifier corresponding to the user terminal, a terminal identifier of the user terminal and authentication information corresponding to the user identifier.
In one embodiment, the micro base station receives the user attribution abnormal information returned by the macro base station to which the micro base station belongs, and determines that the macro base station to which the micro base station belongs cannot execute the authentication process on the user identifier based on the user attribution abnormal information, so that the micro base station responds to the user attribution abnormal information to generate and broadcast third authentication registration request information to the blockchain network, and other micro base stations belonging to the same operator with the user identifier in the blockchain network perform the authentication process on the user terminal corresponding to the user identifier based on the third authentication registration request information.
In one embodiment, in order to prevent the illegal node in the blockchain network from impersonating itself to cause other nodes to have a benefit impaired, the micro base station signs the third authentication registration request information before broadcasting the third authentication registration request information to the blockchain network, for example, signs the third authentication registration request information by using its own private key of the micro base station, and the micro base station broadcasts the signed third authentication registration request information to the blockchain network.
Step S104, acquiring authentication passing messages broadcast by other micro base stations in the block chain network.
The authentication passing message is a message generated after the other micro base station performs an authentication process on the user terminal corresponding to the user identifier based on the third authentication registration request information and determines that the user terminal corresponding to the user identifier passes the authentication. It should be noted that the other micro base station and the user identifier belong to the same operator.
In one embodiment, the generation process of the authentication passing message specifically includes: after the other micro base stations acquire the third authentication registration request information in the blockchain network, firstly verifying whether the signature of the third authentication registration request information passes, for example, verifying whether the signature of the third authentication registration request information is the signature of the micro base station by using a pre-stored micro base station public key corresponding to the micro base station or a micro base station public key corresponding to the micro base station obtained by inquiring the blockchain network, if so, verifying that the signature passes, and if not, verifying that the signature does not pass. After the signature verification of the third authentication registration request information is passed, the other micro base stations extract authentication information corresponding to the user identification from the third authentication registration request information, and send the authentication information corresponding to the user identification to the core network of the operator to which the micro base stations belong through the macro base station to which the micro base stations belong, so that the core network of the operator to which the micro base stations belong carries out network authentication on the user identification corresponding to the user terminal based on the authentication information, thereby obtaining authentication result information of the authentication information corresponding to the user identification, and returning the authentication result information to the other micro base stations of the subordinate through the macro base station of the subordinate. If the authentication result information contains an authentication passing result, the other micro base station generates an authentication passing message based on the authentication passing result; the authentication passing message comprises a terminal identifier of the user terminal, a user identifier corresponding to the user terminal and an authentication passing identifier. After the other micro base stations generate the authentication passing message, the micro base station public key is utilized to sign the authentication passing message, and the signed authentication passing message is broadcasted to the block chain network.
Step S105, providing network access service for the user terminal through the message based on the authentication.
In one embodiment, the micro base station also needs to make the macro base station and the core network to which the macro base station belongs know that the user identifier corresponding to the user terminal has passed authentication. The micro base station sends the authentication passing message to the macro base station before providing network access service for the user terminal based on the authentication passing message, so that the macro base station forwards the authentication passing message to the core network, the core network provides network service for the user terminal based on the authentication passing message, and charges based on the provided network service.
In one embodiment, in order to facilitate management of the macro base station, the micro base station sends the authentication through message to the macro base station to which the micro base station belongs after attaching the micro base station identifier of the micro base station. After the macro base station receives the authentication passing message sent by the micro base station and attached with the micro base station identifier, extracting the terminal identifier of the user terminal, the user identifier corresponding to the user terminal, the micro base station identifier of the micro base station and the authentication passing identifier from the authentication passing message, and writing the terminal identifier of the user terminal, the user identifier corresponding to the user terminal, the micro base station identifier of the micro base station and the authentication passing identifier into a preset relation list. The relation list comprises the corresponding relation among the terminal identifier of the user terminal, the user identifier corresponding to the user terminal, the micro base station identifier of the micro base station and the authentication passing identifier.
In one embodiment, in order to ensure self security, before the micro base station sends the authentication passing message to the affiliated macro base station, firstly, verifying whether the signature of the authentication passing message passes, for example, by using a prestored micro base station public key corresponding to the other micro base station or a micro base station public key corresponding to the other micro base station obtained by inquiring a blockchain network, and verifying whether the signature of the authentication passing message is the signature of the other micro base station, if yes, then, the authentication passes, and if not, then, the authentication does not pass. After verifying that the signature of the authentication passing message passes, the micro base station performs a step of transmitting the authentication passing message to the macro base station to which it belongs.
In one embodiment, after the micro base station provides the network access service for the user terminal through the message based on authentication, when the user terminal performs communication and network service, the user terminal may send a user uplink message to the micro base station, and the micro base station receives the user uplink message of the user terminal and sends the user uplink message to the macro base station to which the micro base station belongs, so that the macro base station forwards the user uplink message to the core network to which the macro base station belongs. In contrast, for the user downlink message, the core network sends the user downlink message to the macro base station, the user downlink message includes the user identifier, the macro base station identifies the micro base station identifier corresponding to the user identifier according to the pre-stored relation list, and forwards the user downlink message to the corresponding micro base station according to the micro base station identifier, and then the micro base station receives the user downlink message forwarded by the macro base station from the affiliated core network, and sends the user downlink message to the user terminal, thereby providing communication and network service for the user terminal. In this process, the core network may charge the user terminal belonging to a different operator from itself, and then perform settlement with the operator to which the user terminal belongs.
Thus, it is achieved that the user terminal of one operator connects to a network (e.g. a 5G network) through the micro base station of another operator and uses network services.
The terminal access method based on the block chain network provided by the embodiment of the invention comprises the steps that the block chain network comprises a plurality of micro base stations belonging to different operators; firstly, generating and transmitting second authentication registration request information to a macro base station to which the second authentication registration request information belongs in response to first authentication registration request information of a user terminal; the second authentication registration request information comprises a user identifier corresponding to the user terminal; secondly, receiving user attribution abnormal information returned by the affiliated macro base station in response to the second authentication registration request information, wherein the user attribution abnormal information comprises information of attributing the user identifier and the macro base station to different operators; then, responding to the abnormal information of the user attribution, generating and broadcasting third authentication registration request information to the blockchain network; the third authentication registration request information comprises a user identifier corresponding to the user terminal; and then, acquiring authentication passing messages broadcast by other micro base stations in the blockchain network, wherein the authentication passing messages are generated after the authentication passing messages are generated by the other micro base stations after determining that the authentication of the user terminal corresponding to the user identifier passes, and the other micro base stations and the user identifier belong to the same operator. And finally, providing network access service for the user terminal through the message based on the authentication, thereby realizing that the same micro base station can provide network access service for users of different operators, saving micro base station resources and improving user experience. In practical application, by using the terminal access method provided by the embodiment of the invention, only one micro base station can be deployed in one home network area without deploying micro base stations of different operators, so that the resources of the micro base stations and the cost of the micro base stations are saved, and meanwhile, the micro base stations can provide 5G network access services for user terminals of different operators in the home network area, such as 5G mobile phone terminals, so that the user experience is improved, and the popularization and development of 5G services are promoted.
As a second aspect of the present invention, an embodiment of the present invention further provides a terminal access method based on a blockchain network, where the method is applied to a micro base station. Wherein the blockchain network includes a plurality of micro base stations belonging to different operators. As shown in fig. 2, the method comprises the steps of:
step S201, obtain third authentication registration request information broadcasted by other micro base stations in the blockchain network.
The third authentication registration request information is generated by other micro base stations based on the first authentication registration request information of the user terminal and sends second authentication registration request information to the macro base station to which the micro base station belongs, and the other micro base stations respond to the information generated by the user attribution abnormal information returned by the macro base station to which the micro base station belongs. The second authentication registration request information includes a user identifier corresponding to the user terminal. The user attribution anomaly information comprises information that the user identification and the macro base station belong to different operators. The third authentication registration request information includes a user identifier corresponding to the user terminal.
In one embodiment, in order to ensure self security, after the micro base station acquires the third authentication registration request information, it is verified whether the signature of the third authentication registration request information passes, for example, by using a pre-stored micro base station common key corresponding to other micro base stations or a micro base station common key corresponding to other micro base stations obtained by querying a blockchain network, if yes, it is verified whether the signature of the third authentication registration request information is the signature of the other micro base stations, if not, it passes. After verifying that the signature of the third authentication registration request information passes, the micro base station performs step S202 described below.
Step S202, based on the third authentication registration request information, the authentication process is carried out on the user terminal corresponding to the user identifier.
In one embodiment, the third authentication registration request information further includes authentication information corresponding to the user identifier. The step of the micro base station performing an authentication process on the user terminal corresponding to the user identifier based on the third authentication registration request information comprises the following steps: firstly, the micro base station extracts authentication information corresponding to the user identifier from third authentication registration request information, and sends the authentication information corresponding to the user identifier to a core network to which the micro base station belongs through the macro base station so that the core network to which the micro base station belongs can perform authentication based on the authentication information and generate authentication result information; and then, the micro base station receives authentication result information returned by the macro base station to which the micro base station belongs, and confirms whether authentication of the user terminal corresponding to the user identifier passes or not based on the authentication result information. Specifically, the authentication result information includes an authentication pass result or an authentication fail result. If the authentication result information contains an authentication failure result, the micro base station determines that the authentication of the user terminal corresponding to the user identifier is not passed; if the authentication result information contains an authentication passing result, the micro base station determines that the authentication of the user terminal corresponding to the user identifier passes.
Step S203, after determining that the authentication of the user terminal corresponding to the user identifier passes, generating and broadcasting an authentication pass message to the block chain network, so that other micro base stations can provide network access service for the user terminal based on the authentication pass message.
