WIPO Patent Application WO/2021/235887
Kind Code:
A1
Abstract:
The present disclosure relates to a communication method and device in a wireless communication system supporting network slicing, and, according to an embodiment of the present disclosure, a method performed by a terminal in a wireless communication system supporting network slicing comprises steps in which: a terminal transmits a session establishment request message for a first network slice through a first access network; a session establishment rejection message is received through the first access network from a network entity for managing a session for the first network slice; and handover to a second access network, which is the preferred access network of the terminal, is determined if the session establishment rejection message includes, as the cause of rejection of the session establishment request, information that indicates the number of sessions exceeding the maximum number of sessions for the first network slice.
