This application relates to a subscription data management method, apparatus, and system. The method includes: a first network element receives, from a second network element, a request message for subscription data; obtains a security token of a terminal device, where the security token is used to verify permission to obtain the subscription data; provides the security token for a blockchain, and queries the blockchain about the subscription data; and if verification succeeds, obtains address information of the subscription data from the blockchain, and sends the address information of the subscription data to the second network element. In the method, the permission to obtain the subscription data is determined by using the blockchain, so that when a subscribed network device does not participate, a visited network device can still obtain the subscription data.

Subscription data management method and apparatus

A blockchain-based roaming transaction method includes sending, by a first network device, a charging data record file to a second network device; publishing, by the first network device, a currency statement to a blockchain; and receiving, by the first network device feedback information of the charging data record file from the second network device.

Blockchain-based roaming transaction method and apparatus

A data sharing method includes that a first network element receives a user data policy from a terminal device. The first network element obtains user information of the terminal device according to the user data policy. The first network element sends the user information of the terminal device to a second network element according to the user data policy.

Data sharing method, device, and system

A subscriber identity management method, a device, and a system. The method includes: a network device that receives a first message from a terminal device, where the first message includes a first subscriber identity number of the terminal device; the network device sends a second message to a blockchain handling function network element, where the second message includes the first subscriber identity number of the terminal device and is used to query routing information of subscriber data associated with the first subscriber identity number; and the network device receives, from the blockchain handling function network element, the routing information of the subscriber data associated with the first subscriber identity number, where the routing information is used to address the subscriber data associated with the first subscriber identity number.
