Abstract
The present disclosure relates to a 5G or 6G communication system for supporting higher data transmission rates. The present invention suggests a method for requesting data usage updates from SMF/PCFs in charge of S-NSSAI/DNN when an access and mobility management function (AMF) receives a session creation request for same S-NSSAI/DNN, a method for requesting data usage updates from PCFs in charge of S-NSSAI/DNN when a unified data repository (UDR) receives a query request for same S-NSSAI/DNN, and a method for selecting same PCF for S-NSSAI and DNN.
Claims20
A method of operating a first session management function (SMF) in a wireless communication system, the method comprising:
- receiving, from an access and mobility management function (AMF), a session management (SM) context creation request message including a policy control function (PCF) identification (ID):
- transmitting, to a first PCE, a policy creation request message based on the SM context creation request message:
- and
- receiving, from the first PCF, a first response message to the policy creation request message.
A first session management function (SMF) in a wireless communication system, the first SMF comprising:
- a transceiver:
- and
- a processor coupled to the transceiver,
- wherein the processor is configured to:
- receive, from an access and mobility management function (AMF), a session management (SM) context creation request message including a policy control function (PCF) identification (ID),
- transmit, to a first PCF, a policy creation request message based on the SM context creation request message, and
- receive, from the first PCF, a first response message to the policy creation request message.
