Network-Based IP Flow Mobility (NBIFOM); Stage 3
The present document specifies the procedures of network-based IP flow mobility (NBIFOM). NBIFOM is based on network mobility protocols (i.e. GTP or PMIP) which is performed between 3GPP access and WLAN access network as specified in 3GPP TS 23.161 [2].
NOTE: IP flow mobility based on PMIP is not supported in this release of the specification.
