Abstract: A method and apparatus of an AMF controller in a wireless communication system are provided. The method and apparatus include: registering a first SIM based on a first registration request message and registering a second SIM based on a second registration request message which has a GUTI for the first SIM. Further, the method and apparatus include: receiving at least one of downlink data and signaling information for the second SIM when a N1 NAS is in CM-Connected state for the first SIM, and transmitting a NAS message indicating at least one of the downlink data and the signaling information for the second SIM over the N1 NAS connection of the first SIM.

Abstract: An apparatus and method for scanning Radio Access Technology (RAT) of a User Equipment (UE) registered in a first cell in a cellular communication network is provided. The method includes performing a Non-Access Stratum (NAS) procedure for establishing a call, disabling, if the NAS procedure fails, capability of the UE to connect to the first cell, checking information relating to neighboring cells in the network, and selecting at least one RAT included in the information relating to the neighboring cells, and scanning a second cell operating in the at least one RAT based on the information relating to the neighboring cells.

Abstract translation: 提供了一种用于扫描注册在蜂窝通信网络中的第一小区中的用户设备（UE）的无线接入技术（RAT）的装置和方法。 该方法包括执行用于建立呼叫的非接入层（NAS）过程，如果NAS过程失败，则禁用UE连接到第一小区的能力，检查与网络中的相邻小区有关的信息，以及在 包括在与相邻小区有关的信息中的至少一个RAT，以及基于与相邻小区有关的信息来扫描在至少一个RAT中操作的第二小区。
