Abstract

The present disclosure relates to a communication method and system for converging a 5G communication system for supporting higher data rates beyond a 4G system with an IoT technology. 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, healthcare, digital education, smart retail, security and safety services. The present disclosure provides a scheme for efficiently operating an UP connection of a session in case where a terminal has a plurality of sessions in a mobile communication system, such as a 5G system, having a network structure in which an AMF for mobility management and an SMF for session management are separated from eachother. Through the present disclosure, a terminal (UE) can optimize a non-access stratum (NAS) signaling message, and can perform data transmission / reception with low latency.

Description

Technical field [0001] The present disclosure relates to a method for efficiently managing UP connection resources of PDU sessions in a cellular wireless communication system. Background technique [0002] In order to meet the demand for wireless data traffic, which is increasing after the commercialization of 4G communication systems, efforts have been made to develop improved 5G or pre-5G communication systems. Therefore, a 5G or pre-5G communication system is also referred to as an ultra-4G network communication system or a post-LTE system. In order to achieve high data rates, it has been considered to implement a 5G communication system in an ultra-high frequency (mmWave) frequency band (for example, such as a 60 GHz frequency band). [0003] In order to reduce the propagation loss of radio waves in the ultra-high frequency band and increase the transmission distance of radio waves, beamforming, massive MIMO, full-dimensional MIMO (FD-MIMO), array antennas, analog beams for 5G...
