Abstract
The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Specifically, disclosed is a method and apparatus for efficiently configuring and applying a policy associated with a roaming user equipment (UE) when an edge computing service is provided via a HR session or an LBO session.
Claims20
A method performed by a first session management function (SMF) entity of a home public land mobile network (HPLMN) in a mobile communication system, the method comprising:
- transmitting, to a policy control function (PCF) entity of the HPLMN, a first message for requesting an offloading policy for a visited public land mobile network (VPLMN), the first message including a serving network identifier of the VPLMN and information indicating that a protocol data unit (PDU) session of the VPLMN supports a home routed session breakout (HR-SBO);
- and
- receiving, from the PCF entity of the HPLMN, a second message including the offloading policy for the PDU session.
A method performed by a policy control function (PCF) entity in a mobile communication system, the method comprising:
- receiving, from a first session management function (SMF) entity of a home public land mobile network (HPLMN), a first message for requesting an offloading policy for a visited public land mobile network (VPLMN), the first message including a serving network identifier of the VPLMN and information indicating that a protocol data unit (PDU) session of the VPLMN supports a home routed session breakout (HR-SBO);
- and
- transmitting, to the first SMF entity of the HPLMN, a second message including the offloading policy for the PDU session.
A first session management function (SMF) entity of a home public land mobile network (HPLMN) in a mobile communication system, the first SMF entity comprising:
- at least one processor;
- and
- at least one memory, communicatively coupled to the at least one processor, storing instructions executable by the at least one processor individually or in any combination to cause the first SMF entity to
- transmit, to a policy control function (PCF) entity of the HPLMN, a first message for requesting an offloading policy for a visited public land mobile network (VPLMN), the first message including a serving network identifier of the VPLMN and information indicating that a protocol data unit (PDU) session of the VPLMN supports a home routed session breakout (HR-SBO), and
- receive, from the PCF entity of the HPLMN, a second message including the offloading policy for the PDU session.
A policy control function (PCF) entity in a mobile communication system, the PCF entity comprising:
- at least one processor;
- and
- at least one memory, communicatively coupled to the at least one processor, storing instructions executable by the at least one processor individually or in any combination to cause the PCF entity to
- receive, from a first session management function (SMF) entity of a home public land mobile network (HPLMN), a first message for requesting an offloading policy for a visited public land mobile network (VPLMN), the first message including a serving network identifier of the VPLMN and information indicating that a protocol data unit (PDU) session of the VPLMN supports a home routed session breakout (HR-SBO), and
- transmit, to the first SMF entity of the HPLMN, a second message including the offloading policy for the PDU session.
