Claim 0:
1. A method of data communication between an access network and a core network, the method comprising:
receiving, by a first wireless access gateway (WAG) in the access network, a first data packet corresponding to a first data flow transmitted from a user equipment (UE), wherein the access network resides outside of the core network, and wherein the core network is a central part of a mobile network to which the first WAG provides direct connectivity;
forwarding, by the first WAG, the first data packet to the core network;
receiving, by a second WAG in the access network, a second data packet transmitted from the UE;
in response to receiving the second data packet, the second WAG determining an identity of the first WAG;
in response to determining the identity of the first WAG, establishing a GPRS Tunneling Protocol (GTP) tunnel connection between the first WAG and the second WAG;
after establishing the GTP tunnel connection, receiving by the second WAG a third data packet corresponding to the first data flow transmitted from the UE;
transmitting, by the second WAG to the first WAG via the GTP tunnel connection, the third data packet; and
forwarding, by the first WAG, the third data packet to the core network.
