The scope of this document is to specify the support of NBIFOM (Network based IP Flow Mobility) i.e. IP flow mobility based on network mobility protocols. This feature supports PDN connections that are simultaneously connected over 3GPP access (i.e. S5/S8 connection to a PDN GW) and a WLAN access (i.e. S2a or S2b connection to the same PDN GW).
