A wireless relay (120) serves User Equipment (UE) (110) over Proxy Mobile Internet Protocol (PMIP) tunnels. The wireless relay (120) receives a wireless network address from a wireless network (140) and a wireline network address from a wireline network (130). The wireless relay (120) receives a bearer request from a network controller (160) that identifies a gateway network address. The wireless relay (120) selects the wireless network address or the wireline network address responsive to the bearer request. In some examples, the wireless relay (120) selects the network address based on a UE ID. The wireless relay (120) generates and transfers a PMIP update that indicates the selected network address to the gateway network address. The wireless relay (120) receives a PMIP response. The wireless relay (120) exchanges user data over the wireless PMIP tunnel if the wireless network address was selected. The wireless relay (120) exchanges the user data over the wireline PMIP tunnel if the wireline network address was selected.
