Feature Description

PCF needs to be aware of UE location, RAT type, access type, and other details to provision relevant policies during the PDU session life cycle. To facilitate this, during PCF initiated policy update procedure, the SMF sends "UeCampingRep" attribute in the response message based on the triggers enabled by PCF.

The SMF sends the UeCampingRep to PCF as per the Table 5.5.2.2-2 defined in 3GPP specification 29.512. When validation of all the PCF provided rules succeed, the SMF sends the UeCampingRep in the update response message to the PCF.

If validation of any of the rules fail, then the SMF sends the ueCampingRep in “PartialSuccessReport” as defined in 4.2.3.2 section of 3GPP specification 29.512.

The fields in the "UeCampingRep" IE are populated based on the following triggers set by PCF.

  • Access type (AC_TY_CH)

  • RAT change (RAT_TY_CH)

  • User location change (SAREA_CH)

  • PLMN Change (PLMN_CH)

The SMF supports the following attributes:

  • accessType

  • ratType

  • servingNetwork

  • userLocationInfo

Important

The SMF currently does not support the ueTimeZone attribute.
