Method and user equipment device for registering in wireless communication system
A user equipment (UE) can perform dual registration with different radio access technology (RAT) system. The UE registers with a core network of a second system independent of a first system while maintaining registration with a core network of the first system. The UE transmits, to the second system, first information indicating that the UE has the registration with the first system when connecting to the second system. One of the first and second systems may be a LTE system using a first radio access technology (RAT), and the other one may be new RAT system using a second RAT different from the first RAT.
