Abstract: A method for establishing a plurality of protocol data unit (PDU) sessions between a user equipment (UE) and a data network (DN) by the UE may comprise transmitting a message to establish the plurality of PDU sessions to at least one network function (NF) of a plurality of NFs, exchanging a signal to establish the plurality of PDU sessions among the UE, a radio access network (RAN), and the plurality of NFs based on the message, and establishing the plurality of PDU sessions between the UE and the DN according to predetermined priority and based on the signal, wherein each of the plurality of PDU sessions corresponds to a network slice (NS) for a particular service, wherein the message includes information about the particular service corresponding to the plurality of PDU sessions, and wherein the priority is determined based on the information about the particular service.

Abstract: The present disclosure relates to a 5G or pre-5G communication system for supporting higher data transmission rates beyond 4G communication systems such as LTE systems.

Abstract: The present invention relates to a method and an apparatus for managing the mobility of a terminal in a mobile agent according to a method for distributive mobility management, and the method according to one embodiment of the present invention comprises: a step for detecting a change in location information of a terminal according to the movement of the terminal and storing the changed location information in a first storage unit; a step for storing, in a second storage unit, an index of the first storage unit in which the changed location information is stored; and a step for transmitting, to another mobile agent, an index value stored in the second storage unit at a point in time at which a predetermined condition is satisfied, and initializing the second storage unit.

Abstract: The present 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). The present disclosure relates to a method and apparatus for selecting a mobility anchor (MA) in a mobile communication system. A method of operating a controller which selects an MA comprises: receiving a bearer configuration request signal from a terminal; acquiring load information for each of a plurality of MAs and mobility information of the terminal; and determining an MA of the terminal on the basis of the load information of each of the plurality of MAs and the mobility information of the terminal.
