Patent ID: 8467358

Claim:
A Radio Access Network (RAN), wherein the RAN communicating with a Mobile Station (MS) of a first network and a Core Network (CN) of a second network comprises: an air interface protocol stack for the first network; a CN interface protocol stack for the second network; and a Mobile Agent (MA), connected to an access layer of the air interface protocol stack for the first network and an access layer of the CN interface protocol stack for the second network, and configured to match and forward signaling messages and data sent by the MS of the first network and the CN of the second network; wherein the access layer of the air interface protocol stack for the first network comprises an access layer of an air interface control-plane protocol stack for the first network and an access layer of an air interface user-plane protocol stack for the first network; the access layer of the CN protocol stack for the second network comprises an access layer of a CN control-plane protocol stack for the second network and an access layer of a CN user-plane protocol stack for the second network; and the MA comprises: a control-plane MA, connected to the access layer of the air interface control-plane protocol stack for the first network and the access layer of the CN interface control-plane protocol stack for the second network, and configured to match and forward the signaling messages sent by the MS of the first network and the CN of the second network; and a user-plane MA, connected to the access layer of the air interface user-plane protocol stack for the first network and the access layer of the CN interface user-plane protocol stack for the second network, and configured to match and forward the data sent by the MS of the first network and the CN of the second network.
