Thanks, Qin I wonder what the rationale is for this. Why would a phone that's already on the Internet connect to the visited network rather than the home network. Is that because of concerns about bandwidth and latency? Anyway, is there a use case for ERP in those cases?

Here are two example use cases adopted by 3GPP.Thes two use cases only work for roaming scenario. In both use cases,IKE negotiation happens between WLAN UE and Packet Data Gateway(PDG) or Tunnel Termination Gateway (TTG). Both PDG and TTG are deployed in 3GPP visited Network. Also we have two cases where IKE is used with the home network belows. Both PDG and TTG are deployed in the 3GPP home netwrok. These two cases only work for non-roaming scenario.
