Abstract
A network terminal, e.g., LTE or 5G, can connect to a home network via a serving network. The terminal can have a terminal identifier (TID), such as an IMEI or other PEI, and a network subscriber can have a subscriber identifier (SID), such as an IMSI or other SUPI. In some nonlimiting examples, a network node can determine that a SID and a TID are authorized for joint use and, in response, transmit authorization information. In some nonlimiting examples, a network node can receive an attach request having verification data and encrypted identification data. The network node can receive decrypted identity data and determine that the identity data corresponds with the verification data. In some nonlimiting examples, the terminal can send an attach request comprising encrypted SID and TID data, and a cryptographic hash, to a network node.
