Internetworking between a next generation core and an evolved core package

摘要

A device of a NextGen user device (NG UE) has one or more baseband processors for decoding a message indicating whether an N26 interface exists between a NextGen core (NGC) and an evolved packet core (EPC), and for initiating a A session continuity mobility method when the NG UE is to be shifted from the NGC to the EPC, the mobility method depending on whether the N26 interface exists or not. The message can be stored in a memory.
