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 packet data network gateway control plane (PGW-C) in a wireless communication system, the method comprising:
- 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.
A method for processing a network slice by a user equipment (UE) in a wireless communication system, the method comprising:
- identifying whether the UE supports slice quota-based operation;
- transmitting, to an MME, a packet data network (PDN) connection request message for accessing a 4th-generation (4G) network based on a result of the identification;
- and
- receiving, from the MME, a PDN connection reject message configured in response to the PDN connection request message.
A packet data network gateway control plane (PGW-C) configured to process a network slice in a wireless communication system, the PGW-C comprising:
- a transceiver;
- and
- a processor coupled with the transceiver and configured to control to:
- receive a session create request message from a mobility management entity (MME),
- identify whether information indicating that a UE supports a slice quota-based operation is included in the session create request message, and
- transmit, to the MME, a session create response message configured based on a result of the identification.
A user equipment (UE) configured to process a network slice in a wireless communication system, the UE comprising:
- a transceiver;
- and
- a processor coupled with the transceiver and configured to control to:
- identify whether the UE supports slice quota-based operation,
- transmit, to a mobility management entity (MME), a packet data network (PDN) connection request message for accessing a 4th-generation (4G) network based on a result of the identification, and
- receive, from the MME, a PDN connection reject message configured in response to the PDN connection request message.
