The invention discloses a registration method. The method comprises the following steps: receiving a registration request message broadcasted by a card-free terminal to acquire a temporary identity label and a private network address carried in information; sending a private network address request message carrying the temporary identity identifier to a first SMF, receiving a private network address returned by the first SMF; if the private network address obtained from the registration request message is consistent with the private network address returned by the first SMF, sending the registration request message; the temporary identity identifier obtained from the registration request message is different from the existing temporary identity identifier; if so, broadcasting a first public network address request message carrying the block chain identifier and the private network address of the card-free terminal in the first block chain, and receiving a first public network address response message broadcasted by a first UPF, obtaining a public network address carried in the first public network address response message, establishing and storing a mapping relationship among the temporary identity identifier, the private network address and the public network address, signing the mapping relationship by using a private key pair, and broadcasting a distribution message carryingthe mapping relationship in the first block chain. Therefore, the card-free UE can be addressed when being called.
Description
technical field [0001] The invention relates to the field of communication technology, in particular to a registration method and device. Background technique [0002] In the prior art, a UE (User Equipment, user equipment) such as a mobile terminal relies on a SIM (Subscriber Identity Module, subscriber identity card) to normally access a 5G (fifth-generation, fifth-generation mobile phone system) network. In 5G session management, the UE will have a formal network identity, and the 5G session management has a complete calling and addressing process for the UE using the SIM card. However, when the cardless UE accesses the 5G network in a certain way, the network identity of the cardless UE is user-defined. If the SMF (Session Management Function, session management function) is the public network allocated by the cardless UE If the address (Internet Protocol Address, Internet Protocol address) is a private address, the call cannot be completed.
