This annex provides a profile description for PS domain online charging in a roaming context, targeting IOT simplification between Operators, while allowing accurate charging models for data usage. GSMA defined RCS services, Video over LTE, some Internet’s application (e.g. Peer to Peer etc.) requiring online charging control of data usage in roaming are examples of the use cases for deployment of such dedicated profile.

This profile relies on a sub-set of capabilities amongst all those defined within this specification for PS domain online charging. Information to be exchanged over Gy and over Gyn is provided as a sub-set of the full message content.

A dedicate profile is designed for each of the following reference points:

– Gy between OCS residing in HPLMN and PCEF located in PGW VPLMN, as per Evolved 3GPP Packet Switched Domain Roaming Architecture for local breakout defined in TS 23.401 [208].

– Gy between OCS residing in HPLMN and PCEF located in IP-Edge fixed broadband access owned by a Convergent fixed-mobile VPLMN, for Non Seamless WLAN Offload (NSWO) 3GPP UEs traffic defined by annex S of TS 23.203 [215].

– Gyn between OCS residing in HPLMN and TDF located in VPLMN for Local Breakout Roaming, as per "Overall PCC architecture for roaming with PCEF in visited network (local breakout)" defined in TS 23.203[72].

– Gyn between OCS residing in HPLMN and TDF owned by a Convergent fixed-mobile VPLMN, for Non Seamless WLAN Offload (NSWO) 3GPP UEs traffic defined by annex S of TS 23.203 [215].
