Abstract
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.
