Detailed Description
The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.
A fifth generation mobile communication network (5th generation mobile networks, 5G) base station is divided into a macro base station and a micro base station, wherein the macro base station is mainly used for outdoor coverage, and the micro base station is 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 the multiple operators all need network services. Then, the micro base stations belonging to different operators need to be deployed in the indoor area, that is, the micro base stations need to be deployed repeatedly, which causes resource waste and poor user experience.
In order to solve the above problem, an embodiment of the present invention provides a terminal access method based on a block chain network. The blockchain network is a alliance blockchain network, the originator nodes are different operators, and the founding blocks of the blockchain network comprise operator identity information and operator public keys of the different operators. When the block chain network is constructed, different operators respectively use own private keys of the operators to sign the micro base station information lists of the subordinate micro base stations, the signed micro base station information lists are broadcasted to the block chain network, and the accounting nodes of the block chain network store the micro base station information lists broadcasted by the different operators and belonged to the block chain information lists in a block chain account book of the block chain network. The micro base station information list comprises micro base station identifications corresponding to micro base stations of different operators, micro base station public keys and other information. 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 to a unified block chain network, and different micro base stations can be in communication 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 micro base station. The micro base station is also connected to a network in a certain area, such as a home network, and is in signal connection with a user terminal (such as a mobile phone) in a 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 block chain network, where the method is applied to the micro base station, and as shown in fig. 1, 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 macro base station.
The user terminal may be a mobile terminal, such as a 5G mobile phone terminal. The second authentication registration request message 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 message includes but is not limited to: the terminal identifier of the user terminal, the user identifier (e.g. mobile phone number) corresponding to the user terminal, and the authentication information corresponding to the user identifier. The micro base station responds to the first authentication registration request information, writes the micro base station identification of the micro base station in the first authentication registration request information, and generates second authentication registration request information, namely the second authentication registration request information comprises the micro base station identification of the micro base station besides 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 then, the micro base station sends the generated second authentication registration request information to the macro base station.
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 can identify whether the user identifier included in the second authentication registration request information belongs to the registered user identifier of the operator to which the core network belongs based on the second authentication registration request information, that is, identify whether the user identifier is the user of the operator to which the core network belongs. If the core network to which the macro base station belongs identifies that the user identifier is a registered user identifier belonging to an operator to which the core network belongs, namely the user identifier and the macro base station belong to the same operator, the core network performs authentication according to the 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 identifies that the user identifier is not the registered user identifier of the operator to which the core network 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 receiving the user attribution abnormal information, the macro base station forwards the user attribution abnormal information to the corresponding subordinate micro base station. The user attribution abnormal information comprises information that the user identification and the macro base station belong to different operators.
And step S102, receiving user attribution abnormal information returned by the macro base station responding to the second authentication and registration request information.
The user attribution abnormal information comprises a terminal identification, a user identification corresponding to the terminal identification and information that the user identification and the macro base station belong to different operators.
Step S103, responding to the user attribution abnormal information, generating and broadcasting third authentication registration request information to the block chain network.
The third authentication registration request information includes 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 exception 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 perform the authentication process on the user identifier based on the user attribution exception information, so that the micro base station generates and broadcasts third authentication registration request information to the block chain network in response to the user attribution exception information, so that other micro base stations belonging to the same operator as the user identifier in the block chain 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 damage the benefits of other nodes, 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 broadcasts the signed third authentication registration request information to the blockchain network.
Step S104, obtaining the authentication passing message broadcast by other micro base stations in the block chain network.
The authentication passing message is a message generated after the authentication of the user terminal corresponding to the user identifier is determined to pass by the authentication passing message of the user terminal corresponding to the user identifier, which is performed by the other micro base station based on the third authentication registration request information. It should be noted that the other micro base station and the subscriber identity belong to the same operator.
In one embodiment, the process of generating the authentication passing message specifically includes: after acquiring the third authentication registration request information in the blockchain network, the other micro base stations first verify whether the signature of the third authentication registration request information passes, for example, 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 querying the blockchain network, verify whether the signature of the third authentication registration request information is the signature of the micro base station, if so, the verification passes, and if not, the verification 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 identifier from the third authentication registration request information, and send the authentication information corresponding to the user identifier to the core network of the operator to which the micro base stations belong through the macro base station to allow the core network of the operator to perform network authentication on the user identifier corresponding to the user terminal based on the authentication information, so that authentication result information corresponding to the user identifier is obtained, and the authentication result information is returned to the other subordinate micro base stations through the subordinate macro base station. If the authentication result information contains an authentication passing result, the other micro base stations generate 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. And after the other micro base stations generate the authentication passing message, signing the authentication passing message by using the public key of the micro base station, and broadcasting the signed authentication passing message to the block chain network.
Step S105, based on the authentication, the user terminal is provided with the network access service through the message.
In one embodiment, the micro base station further needs to make the macro base station and the core network know that the user identifier corresponding to the user terminal has been authenticated. Before the micro base station provides the network access service for the user terminal based on the authentication passing message, the micro base station sends the authentication passing message to the macro base station to allow the macro base station to forward the authentication passing message to the core network, so that the core network provides the network service for the user terminal based on the authentication passing message, and the charging is carried out based on the provided network service.
In one embodiment, in order to facilitate management by the macro base station, the micro base station adds the authentication passing message to its own micro base station identifier and sends the authentication passing message to the macro base station to which the micro base station belongs. After receiving the authentication passing message which is sent by the micro base station and is added with the micro base station identification, the macro base station extracts the terminal identification of the user terminal, the user identification corresponding to the user terminal, the micro base station identification of the micro base station and the authentication passing identification from the authentication passing message, and writes the terminal identification of the user terminal, the user identification corresponding to the user terminal, the micro base station identification of the micro base station and the authentication passing identification into a preset relation list. The relation list comprises the corresponding relation of the terminal identification of the user terminal, the user identification corresponding to the user terminal, the micro base station identification of the micro base station and the authentication passing identification.
In one embodiment, in order to ensure the security of the micro base station, before the micro base station sends the authentication passing message to the macro base station to which the micro base station belongs, it is first verified whether the signature of the authentication passing message passes, for example, by using a pre-stored public key of the micro base station corresponding to the other micro base station or a public key of the micro base station corresponding to the other micro base station obtained by querying a block chain network, whether the signature of the authentication passing message is the signature of the other micro base station is verified, if so, the verification passes, and if not, the verification does not pass. And after verifying that the signature of the authentication passing message passes, the micro base station executes the step of sending the authentication passing message to the macro base station to which the micro base station belongs.
In one embodiment, after the micro base station provides the network access service for the user terminal through the message based on the 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. On the contrary, for the user downlink message, the core network sends the user downlink message to the macro base station, the user downlink message includes a 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 core network to which the micro base station belongs, and sends the user downlink message to the user terminal, thereby providing communication and network service for the user terminal. It should be noted that, in this process, the core network may perform charging for the user terminal belonging to a different operator from itself, and then perform settlement with the operator to which the user terminal belongs.
Up to this point, it is realized that a user terminal of one operator connects to a network (e.g. a 5G network) through a micro base station of another operator and uses a network service.
The terminal access method based on the block chain network provided by the embodiment of the invention, wherein the block chain network comprises a plurality of micro base stations belonging to different operators; firstly, responding to first authentication registration request information of a user terminal, and generating and sending second authentication registration request information to a macro base station to which the user terminal belongs; the second authentication registration request information comprises a user identifier corresponding to the user terminal; secondly, receiving user attribution abnormal information returned by the macro base station responding to the second authentication registration request information, wherein the user attribution abnormal information comprises information that the user identification and the macro base station belong to different operators; then, responding to the user attribution abnormal information, 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; and then, acquiring an authentication passing message broadcast by other micro base stations in the block chain network, wherein the authentication passing message is a message generated by the other micro base stations performing an authentication process on the user terminal corresponding to the user identifier based on the third authentication registration request information and after determining that the user terminal corresponding to the user identifier passes the authentication, and the other micro base stations and the user identifier belong to the same operator. Finally, the network access service is provided for the user terminal through the message based on the authentication, so that the same micro base station can provide the network access service for users of different operators, the micro base station resources are saved, and the user experience is improved. 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 micro base station resources and micro base station cost are saved, and meanwhile, the micro base station can provide 5G network access service for user terminals of different operators in the home network area, such as 5G mobile phone terminals, so that user experience is improved, and 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 block chain network, where the method is applied to a micro base station. Wherein the blockchain network comprises a plurality of micro base stations belonging to different operators. As shown in fig. 2, the method comprises the steps of:
step S201, obtaining third authentication registration request information broadcast by other micro base stations in the blockchain network.
And the third authentication registration request information is generated by other micro base stations responding to the user attribution abnormal information returned by the macro base station to which the other micro base stations belong after the other micro base stations generate and send the second authentication registration request information to the macro base station to which the other micro base stations belong based on the first authentication registration request information of the user terminal. The second authentication registration request message includes a user identifier corresponding to the user terminal. The user attribution abnormal information comprises information that the user identification and the macro base station belong to different operators. The third authentication registration request message contains a user identifier corresponding to the user terminal.
In one embodiment, in order to ensure the security of the femto base station, after obtaining the third authentication registration request message, the femto base station verifies whether the signature of the third authentication registration request message passes through, for example, by using a pre-stored public key of the femto base station corresponding to another femto base station or a public key of the femto base station corresponding to another femto base station obtained by querying a block chain network, and verifies whether the signature of the third authentication registration request message is the signature of the other femto base station, if so, the verification passes, and if not, the verification does not pass. After the micro base station verifies that the signature of the third authentication registration request message passes, the following step S202 is performed.
Step S202, based on the third authentication registration request information, the authentication process is performed on the user terminal corresponding to the user identifier.
In one embodiment, the third authentication registration request message 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 includes: firstly, the micro base station extracts authentication information corresponding to the user identification from the third authentication registration request information, and sends the authentication information corresponding to the user identification to the core network through the macro base station to which the micro base station belongs so that the core network to which the micro base station belongs can authenticate based on the authentication information and generate authentication result information; 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 the authentication of the user terminal corresponding to the user identification 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 identification does not pass; and if the authentication result information contains an authentication passing result, the micro base station determines that the user terminal corresponding to the user identification passes the authentication.
Step S203, after determining that the user terminal corresponding to the user identifier passes the authentication, generating and broadcasting an authentication passing message to the blockchain network, so that other micro base stations provide network access service for the user terminal based on the authentication passing message.
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.
