Abstract

According to an aspect of the present invention, there is provided an interworking method between networks of a user equipment (UE) in a wireless communication system, including: performing a first interworking procedure for changing a network of the UE from a 5-generation core network (5GC) network to an evolved packet core (EPC) network, wherein, when an interface between the 5GC and the EPC networks does not exist, the performing of the first interworking procedure includes: receiving a first indication from an access and mobility management function (AMF) of the 5GC network; and performinga handover attach procedure in the EPC network based on the first indication.

Description

technical field [0001] The present invention relates to wireless communication, and more particularly, to an interworking method between networks and an apparatus used for the method. Background technique [0002] A mobile communication system has been developed to provide voice services while ensuring user activity. However, the mobile communication system expands the area to data service as well as voice, and currently, resource shortage phenomenon is caused due to explosive increase of traffic and use requires higher speed service, and as a result, a more developed mobile communication system is required. [0003] The requirements of the next-generation mobile communication system mainly need to support the accommodation of explosive data services, an epoch-making increase in the transmission rate of each user, a significant increase in the number of connected devices, very low end-to-end delay, and high energy efficiency. To this end, various technologies have been rese...
