Abstract: In an example, a wireless communication system and apparatuses thereof are described. In an example long-term evolution (LTE) network, a first base station hands over a connection to a second base station. The first base station may be a (femto) home eNodeB (HeNB) or (macro) eNodeB. The second base station may also be a HeNB or eNodeB connected to a different gateway. The first base station may send “Handover Request” on an X2 connection, identifying the gateway that the second base station is connected to as the correct gateway. After sending a “Handover Request Acknowledgement,” the second base station correctly establishes a tunnel to a connected gateway device.
