A.6 Charging Characteristics in P-GW

32.2513GPPCharging managementPacket Switched (PS) domain chargingRelease 17Telecommunication managementTS

The P-GW shall apply Charging Characteristics to its IP-CAN bearers. It shall either apply the SGSN/S-GW/ePDG supplied parameters, or it may be configured to ignore the SGSN/S-GW/ePDG supplied Charging Characteristics in any combination of the following cases:

– visiting case, i.e. the subscriber belongs to a different PLMN;

– roaming case, i.e. the subscriber belongs to same PLMN and the SGSN/S-GW/ePDG belongs to a different PLMN;

– home case, i.e. the subscriber belongs to the same PLMN as the SGSN/S-GW/ePDG and P-GW; or

– unconditionally, i.e. it always ignores the SGSN/S-GW/ePDG supplied parameters.

If the P-GW ignores the parameters supplied by the SGSN/S-GW/ePDG, it shall nevertheless accept the IP-CAN session request. It shall then apply its own pre‑configured Charging Characteristics as appropriate, i.e. the home, visiting or roaming behaviour. The P-GW shall support the configuration of one set of default Charging Characteristics (i.e. home, visiting, roaming) for each of its supported APNs.
