`ABSTRACT
`
`A communications architecture for enabling IP-based
`mobile communications includes a Local Service Function
`(LSF) component configured to serve as an IP-based serving
`area networkfor a set of x-Access Networks, and a Network
`Service Function (NSF) component configured to serve as
`an IP-based home network by managing a MN’s subscrip-
`tion and associated profile so that the MN is authorized to
`use the resources of the LSF. An x-Access Network (xAN)
`is interconnected to the LSF and NSF for providing hetero-
`geneous Layer 2 access for MNsirrespective of access
`technology.
