Abstract

The invention discloses a call addressing method, comprising: receiving a call request, and if the called number carried in the call request is a non-standard number, broadcasting a first internetwork carrying the called number in a first block chain Protocol IP address request message, the called number is the temporary identity of the called end, and the first IP address response message broadcasted by the public node in the second blockchain and the first blockchain is received, wherein the second blockchain is the called party's temporary identity. The blockchain of the network of the second operator to which the calling terminal belongs. The second operator is different from the operator to which the device belongs, obtains the IP address in the response message of the first IP address, and forwards the call request according to the IP address. The call addressing method provided by the embodiment of the present invention can provide the addressability of the cardless UE when being called, and improve the communication convenience of the cardless UE.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a call addressing 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 (SubscriberIdentity Module, subscriber identity card) to normally access a 5G (fifth-generation, fifth-generation mobile phone system) network, and once it accesses the 5G network In , the UE will have a formal network identity, and the 5G session management has a complete calling and addressing process for UEs using SIM cards. However, when the cardless UE accesses the 5G network in a certain way, the network identity of the cardless UE is user-defined, and generally it can only initiate calls or access externally, but cannot be called or addressed. Therefore, the development of cardless UE is greatly restricted. SUMMARY OF THE INVENTION [0003] To this end, the present invention provides a call...
