为了解决上述难题,本发明实施例提供基于共享基站的终端接入方法。图1为本发明实施例提供的一种基于共享基站的终端接入方法。其中,共享基站指的是能够同时服务于多个运营商的基站,例如5G(5th generation mobile networks,第五代移动通信网络)共享基站。该共享基站是携号转网公告区块链网络中的节点,该携号转网公告区块链网络的节点还包括多个运营商的运营商系统。In order to solve the above problems, an embodiment of the present invention provides a terminal access method based on a shared base station. FIG. 1 is a terminal access method based on a shared base station provided by an embodiment of the present invention. Wherein, the shared base station refers to a base station capable of serving multiple operators at the same time, such as a 5G (5th generation mobile networks, fifth generation mobile communication network) shared base station. The shared base station is a node in the number portability transfer announcement blockchain network, and the number portability transfer announcement blockchain network nodes also include operator systems of multiple operators.

如图1所示,该基于共享基站的终端接入方法,包括以下步骤:步骤S101-步骤S103。As shown in FIG. 1 , the terminal access method based on a shared base station includes the following steps: Step S101-Step S103.

步骤S101、根据预先获取的用户终端的终端号码,从携号转网公告区块链网络中查询与终端号码对应的携号转网信息。Step S101, according to the pre-acquired terminal number of the user terminal, query the number portability information corresponding to the terminal number from the number portability transfer announcement blockchain network.

其中,用户终端例如可以是手机、IPAD等移动终端,终端号码例如可以是手机号码。携号转网公告区块链网络是各运营商共同构建的用于记录携号转网信息的区块链网络。该携号转网公告区块链网络的节点包括多个运营商系统、至少一个共享基站和至少一个用户终端。该携号转网信息是终端号码对应的当前运营商系统预先广播在携号转网公告区块链网络中的信息。Wherein, the user terminal may be, for example, a mobile terminal such as a mobile phone or an IPAD, and the terminal number may be, for example, a mobile phone number. The number portability transfer announcement block chain network is a block chain network jointly constructed by various operators to record the number portability transfer information. The nodes of the number portability transfer announcement blockchain network include multiple operator systems, at least one shared base station and at least one user terminal. The number portability transfer information is the information that the current operator system corresponding to the terminal number pre-broadcasts in the number portability transfer announcement blockchain network.

在一个实施方式中,终端号码对应的用户携号转入运营商系统的情况下,该运营商系统生成并广播该终端号码的携号转网信息至携号转网公告区块链网络,该携号转网信息用于公告该终端号码对应的用户已携号转入该运营商系统。该携号转网信息存储在该携号转网公告区块链网络的区块链账本中,能够被追溯查询。其中,携号转网信息包含终端号码和终端号码对应的当前运营商系统的标识信息。终端号码对应的当前运营商系统即为终端号码携号转入的运营商系统。In one embodiment, when the user corresponding to the terminal number transfers the number to the operator system, the operator system generates and broadcasts the number portability transfer information of the terminal number to the number portability announcement blockchain network. The number portability information is used to announce that the user corresponding to the terminal number has ported the number to the operator system. The number portability transfer information is stored in the blockchain account book of the number portability transfer announcement blockchain network, and can be retrospectively queried. Wherein, the number portability information includes the terminal number and identification information of the current operator system corresponding to the terminal number. The current operator system corresponding to the terminal number is the operator system to which the terminal number is ported.

在一个实施方式中,共享基站可以以预先获取的用户终端的终端号码作为索引,从携号转网公告区块链网络的区块链账本中查询与终端号码对应的携号转网信息。In one embodiment, the shared base station can use the pre-acquired terminal number of the user terminal as an index to query the number portability information corresponding to the terminal number from the blockchain ledger of the number portability announcement blockchain network.

在一个实施方式中,运营商系统每隔预设时间间隔广播自身对应的AMF列表至携号转网公告区块链网络中。其中,AMF列表包含该运营商系统的标识信息、多个AMF的标识信息和各AMF对应的位置信息。预设时间间隔可以根据具体实施场景进行配置,例如12小时。在本实施方式中,为了避免恶意节点冒充,运营商系统可以对该AMF列表进行私钥签名,然后广播经私钥签名后的AMF列表。In one embodiment, the operator system broadcasts its corresponding AMF list to the number portability transfer announcement blockchain network every preset time interval. Wherein, the AMF list includes identification information of the operator system, identification information of multiple AMFs, and location information corresponding to each AMF. The preset time interval can be configured according to a specific implementation scenario, for example, 12 hours. In this embodiment, in order to avoid masquerading as a malicious node, the operator system can sign the AMF list with a private key, and then broadcast the AMF list signed by the private key.

图2为本发明实施例提供的另一种基于共享基站的终端接入方法。在一个实施方式中,在上述步骤S101之前,即共享基站根据预先获取的用户终端的终端号码,从携号转网公告区块链网络中查询与终端号码对应的携号转网信息之前,如图2所示,基于共享基站的终端接入方法还包括:步骤S201和步骤S202。FIG. 2 is another terminal access method based on a shared base station provided by an embodiment of the present invention.

步骤S201、基于用户终端发起的小区搜索过程与用户终端建立连接,并获取用户终端的终端号码和终端位置。Step S201, establish a connection with the user terminal based on the cell search process initiated by the user terminal, and obtain the terminal number and terminal location of the user terminal.

在一个实施方式中,为了维护共享基站的基本功能、保障终端接入,共享基站基于用户终端发起的小区搜索过程与用户终端建立连接之前,还包括:In one embodiment, in order to maintain the basic functions of the shared base station and ensure terminal access, before the shared base station establishes a connection with the user terminal based on the cell search process initiated by the user terminal, it further includes:

步骤S202、接入携号转网公告区块链网络,并与多个运营商系统对应的AMF(接入和移动性管理功能实体)和SMF(Session Management Function,会话管理功能实体)建立连接关系。Step S202, accessing the number portability transfer announcement blockchain network, and establishing a connection relationship with AMF (Access and Mobility Management Function Entity) and SMF (Session Management Function, Session Management Function Entity) corresponding to multiple operator systems .

在一些实施例中,多个运营商系统对应的AMF和SMF可以通过各自的核心网或者光纤与共享基站可以建立连接关系。In some embodiments, AMFs and SMFs corresponding to systems of multiple operators may establish a connection relationship with a shared base station through respective core networks or optical fibers.

步骤S102、在查询到终端号码对应的携号转网信息的情况下,基于携号转网信息确定出终端号码对应的当前运营商系统。Step S102, if the number portability information corresponding to the terminal number is found, determine the current operator system corresponding to the terminal number based on the number portability information.

其中,携号转网信息包含终端号码和终端号码对应的当前运营商系统的标识信息,根据该标识信息即可以确定终端号码对应的当前运营商系统。Wherein, the number portability information includes the terminal number and identification information of the current operator system corresponding to the terminal number, and the current operator system corresponding to the terminal number can be determined according to the identification information.

步骤S103、基于预先获取的用户终端的终端位置和当前运营商系统对应的AMF列表,确定出目标AMF,并通过目标AMF为用户终端提供接入注册。Step S103: Determine the target AMF based on the pre-acquired terminal location of the user terminal and the AMF list corresponding to the current operator system, and provide access registration for the user terminal through the target AMF.

其中,当前运营商系统对应的AMF列表包含该当前运营商系统的标识信息、多个AMF的标识信息和多个AMF各自对应的位置信息。目标AMF指的是当前运营商系统对应的AMF列表中包括的与用户终端的终端位置对应的AMF。Wherein, the AMF list corresponding to the current operator system includes identification information of the current operator system, identification information of multiple AMFs, and location information corresponding to each of the multiple AMFs. The target AMF refers to the AMF corresponding to the terminal location of the user terminal included in the AMF list corresponding to the current operator system.

图3为本发明实施例提供的一种获取当前运营商系统对应的AMF列表的流程图。在一个实施方式中,在上述步骤S103之前,即基于预先获取的用户终端的终端位置和当前运营商系统对应的AMF列表,确定出目标AMF之前,如图3所示,还包括:步骤S301。Fig. 3 is a flow chart of obtaining an AMF list corresponding to the current operator system provided by an embodiment of the present invention. In one embodiment, before the above step S103, that is, before the target AMF is determined based on the pre-acquired terminal location of the user terminal and the AMF list corresponding to the current operator system, as shown in FIG. 3 , further includes: Step S301.

步骤S301、从携号转网公告区块链网络中获取当前运营商系统对应的AMF列表;或者,从本地信息中获取当前运营商系统对应的AMF列表。Step S301. Obtain the AMF list corresponding to the current operator system from the number portability transfer announcement blockchain network; or obtain the AMF list corresponding to the current operator system from local information.

需要说明的是,在一些实施场景中,共享基站可以在本地维护当前运营商系统对应AMF列表。在共享基站在本地维护当前运营商系统对应AMF列表的情况下,共享基站可以从本地信息中获取当前运营商系统对应的AMF列表。在共享基站在没有在本地维护当前运营商系统对应AMF列表的情况下,共享基站可以从携号转网公告区块链网络中获取当前运营商系统对应的AMF列表。It should be noted that, in some implementation scenarios, the shared base station may locally maintain the AMF list corresponding to the current operator system. In the case that the shared base station maintains the AMF list corresponding to the current operator system locally, the shared base station can acquire the AMF list corresponding to the current operator system from local information. In the case that the shared base station does not maintain the AMF list corresponding to the current operator system locally, the shared base station can obtain the AMF list corresponding to the current operator system from the number portability announcement blockchain network.

在一个实施方式中,在上述步骤S101之后,即根据预先获取的用户终端的终端号码,从携号转网公告区块链网络中查询终端号码对应的携号转网信息之后,还包括:在未查询到终端号码对应的携号转网信息的情况下,基于终端号码获取终端号码对应的初始运营商系统,基于预先获取的用户终端的终端位置和初始运营商系统对应的AMF列表,确定出目标AMF,并基于目标AMF为用户终端提供接入注册。In one embodiment, after the above step S101, that is, after querying the number portability information corresponding to the terminal number from the number portability transfer announcement blockchain network according to the pre-acquired terminal number of the user terminal, it also includes: If the number portability information corresponding to the terminal number is not found, the initial operator system corresponding to the terminal number is obtained based on the terminal number, and based on the pre-acquired terminal location of the user terminal and the AMF list corresponding to the initial operator system, determine the The target AMF provides access registration for the user terminal based on the target AMF.

其中,初始运营商系统对应的AMF列表可以采用如步骤S301描述的方式获取。Wherein, the AMF list corresponding to the initial operator system may be acquired in the manner described in step S301.
