Abstract: The disclosure relates to a pre-5th-generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-generation (4G) communication system, such as long term evolution (LTE). A method and an apparatus for managing radio access network (RAN) nodes in a communication network are provided. The method includes receiving tracking area identity (TAI) indicating locality, from added RAN nodes, determining whether locality of RAN nodes corresponds to primary or secondary serving localities of access and mobility management function (AMF), based on pre-stored TAI list, identifying relative AMF capacity (RAC) value for RAN nodes and transmitting RAC value to RAN nodes.

Abstract: Apparatus and method for controlling handover are disclosed. The solution comprises obtaining information on slices supported by surrounding base stations; obtaining information on overloaded slices used by the surrounding base stations; receiving a measurement report from a user terminal utilizing slices in communication; determining based on the measurement report that a handover is needed for the user terminal; selecting from the surrounding base stations a target base station for handover based on the measurement report, slices supported by the base stations and the information on overloaded slices.
