5G NSA Method and Apparatus for Establishing Bearer in 5G NSA Environment

摘要

The present invention relates to a method for setting up a bearer in a 5G NSA environment, and an apparatus and system therefor, and a first base station providing Long Term Evolution (LTE) coverage and a first base station providing NR (New Radio) coverage according to an embodiment. 2 In a 5G Non-StandAlone (NSA) system including a base station, the bearer setting method includes the steps of receiving a service request message from a terminal through a mobility management entity (MME), the first base station, and the first base station. Checking whether a first base station is connected to the second base station and, as a result of the check, if the first base station is connected to the second base station, performing a measurement procedure with the terminal at the first base station; and The first base station may include determining whether the terminal is in a 5G service area based on the measurement procedure, and if the determination result is in the 5G service area, setting a 5G bearer through the second base station. have.
