    Abstract: The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. The present disclosure discloses a method for controlling and paging a user equipment (UE). In the method, an access network node receives mobility level information of a UE; and the access network node performs handover control and/or measurement control and/or paging for the UE according to mobility level information of the UE. Provided with the present disclosure, system resources can be saved and overall system performance can be improved. The present disclosure further provides a method and device for selecting a core network for a User Equipment (UE) by an enhanced Long Term Evolution (LTE) base station. The method comprises the steps of: establishing a radio resource control (RRC) connection to a UE; selecting a core network corresponding to the UE according to a preset condition; receiving a response message transmitted by the corresponding core network; and, transmitting a RRC configuration message to the UE to configure or reconfigure a user plane for the UE. The method of the present disclosure can select a proper core network for a terminal, so that a UE in 5G can use the features of 5G to increase the amount of user data and the utilization rate of network frequency.
