Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Provided are an access and mobility management function (AMF) and a method performed by an AMF, including receiving, from a terminal, a registration request message for a protocol data unit (PDU) session including information on a requested slice associated with the PDU session; determining whether the requested slice is allowed and whether the requested slice is for a network slice admission control (NSAC); if the requested slice is allowed for the terminal and is for the NSAC, determining whether the requested slice is exempt from the NSAC for the PDU session; and if the requested slice is exempt from the NSAC for the PDU session, transmitting, to the terminal, a registration accept message as a response to the registration request message.

Abstract: A method and device for providing an exemption from a network slice bitrate limitation are provided. A method performed by an access and mobility management function (AMF) in a wireless communication system supporting bitrate limitation for a network slice is provided. The method includes receiving, via a radio access network (RAN) from a user equipment (UE), information a first message including cause information associated with allowable maximum bitrate (MBR) for the UE, and determining, based on the cause information, whether to transmit information related to an exemption of the bitrate limitation to the RAN.
