Problems solved by technology

However, in the case of dual-registration interworking, since terminal mobility is supported by the connection procedure between the terminal and the network without transmitting the inter-eNB handover signal, it is difficult to apply general communication technology to this

Abstract

The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates beyond a 4th-Generation (4G) communication system such as Long Term Evolution (LTE). The embodiments in the present disclosure allow to transfer remaining data between different base stations in a dual-registration interworking process, which provides terminal mobility between 4G and 5G networks without a data loss. Further, it provides the terminal mobility with no data loss without changing 5G and 4G base station implementation through addition of a simple function of new equipment, such as SMF and UPF. Further, it supports different QoS and forwarding path units in the 5G and 4G networks without changing 5G and 4G base station functions. Further, it exempts additional function implementation costs for re-ordering in a terminal and a network through in-order delivery of packets to the terminal without changing the packet order during 4G-5G network movement.

Description

technical field [0001] The present disclosure relates to an apparatus for providing a service without data loss during a terminal moving between 5G and 4G mobile communication systems and an operating method thereof. Background technique [0002] In order to meet the demand for wireless data traffic that has increased since the deployment of 4G communication systems, efforts have been made to develop improved 5G or quasi-5G communication systems. Therefore, the 5G or quasi-5G communication system is also called "super 4G network" or "post-LTE system". [0003] 5G communication systems are considered to be implemented in higher frequency (mmWave) frequency bands (eg, 60GHz frequency band) in order to achieve higher data rates. In order to reduce the propagation loss of radio waves and increase the transmission distance, beamforming, massive multiple-input multiple-output (MIMO), full-dimensional MIMO (FD-MIMO), array antennas, analog beamforming, large scale antenna technol...
