Abstract
The disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). A method for processing a network slice by a packet data network gateway control plane (PGW-C) in a wireless communication system is provided. The method includes receiving a session create request message from a mobility management entity (MME), identifying whether information indicating that a user equipment (UE) supports a slice quota-based operation is included in the session create request message, and transmitting, to the MME, a session create response message configured based on a result of the identification.
Claims12
A method for processing a network slice by a session management function and packet data network gateway control plane (SMF+PGW-C) in a wireless communication system, the method comprising:
- identifying that a network slice admission control is supported in case of evolved packet core (EPC) interworking, wherein the network slice admission control is associated with at least one of a maximum number of user equipments (UEs) per network slice in EPC and a maximum number of protocol data unit (PDU) sessions per network slice in the EPC;
- and
- selecting, by the SMF+PGW-C, a single network slice selection assistance information (S-NSSAI) associated with a packet data network (PDN) connection during PDN connection establishment in the EPC, wherein the network slice is identified by the S-NSSAI.
A session management function and packet data network gateway control plane (SMF+PGW-C) in a wireless communication system, the SMF+PGW-C comprising:
- a transceiver;
- and
- a processor coupled with the transceiver and configured to control to:
- identify that a network slice admission control is supported in case of evolved packet core (EPC) interworking, wherein the network slice admission control is associated with at least one of a maximum number of user equipments (UEs) per network slice in EPC and a maximum number of protocol data unit (PDU) sessions per network slice in the EPC;
- and
- select, by the SMF+PGW-C, a single network slice selection assistance information (S-NSSAI) associated with a packet data network (PDN) connection during PDN connection establishment in the EPC, wherein the network slice is identified by the S-NSSAI.
