A wireless relay serves User Equipment (UE) over a wireless Proxy Mobile Internet Protocol (PMIP) tunnel and a wireline PMIP tunnel to a Local Mobility Anchor (LMA). The wireless relay receives a wireless network address, a wireline network address, and an LMA network address. The wireless relay receives a request for a UE bearer and selects the wireless network or the wireline network. A Media Access Gateway (MAG) in the wireless relay transfers a PMIP update to the LMA that indicates the wireless network address or wireline network address based on the selected network. The wireless relay wirelessly exchanges user data with the UE. The MAG exchanges the user data with the LMA over the wireless PMIP tunnel or the wireline PMIP tunnel based on the selected network.
