TABLE 1 Exemplary Backhaul Characteristics Backhaul Technology Latency (one way) Throughput Fiber Access 1 10-30 ms 10M-10 Gbps Fiber Access 2 5-10 ms 100-1000 Mbps DSL Access 15-60 ms 10-100 Mbps Cable 25-35 ms 10-100 Mbps Wireless Backhaul 5-35 ms 10 Mbps-100 Mbps
For example, existing solutions for handovers between cellular base stations rely on signaling and data forwarding over an X2 interface (see, for example, 3GPP TS 36.423 v11.2.0 September 2012) between base stations. However, the X2 interface may require traversal on a pseudo-wire connection for uplink and another traversal for downlink. This produces a tromboning effect due to multiple traversals of the backhaul infrastructure, which not only increases delay but also increases the amount of bandwidth consumed in the backhaul network. Such increased bandwidth in turn increases the cost of the leased backhaul facilities.

1. A method at a small cell access point of a network for offloading a wireless device in a macro cell of the network, the method comprising:
adding the small cell access point to the wireless device using control signaling received over the radio link signaling connection, the adding comprising:
signaling over the radio link signaling connection to determine whether the small cell access point has capacity to service the wireless device;
receiving a pairwise master key from the base station, the pairwise master key being randomly generated at the base station upon said adding
authenticating the wireless device using the pairwise master key and data from the association request; and
establishing a backhaul connection between the small cell access point and a traffic interchange point for user plane traffic;

2. The method of claim 1, wherein the small cell access point communicates with wireless devices over an 802.11 interface.
using information within the association preparation message to bind user plane traffic for the wireless device from-the traffic interchange point to the small cell access point.
4. The method of claim 1, further comprising signaling to the base station of the macro cell over the radio link signaling connection once authentication is complete.
5. A small cell access point for offloading a wireless device in a macro cell, the small cell access point and the macro cell being part of a network, comprising:
wherein the small cell access point is configured to:
add the small cell access point to the wireless device using control signaling received over the radio link signaling connection, the adding comprising:
receiving a pairwise master key from the base station, the pairwise master key being randomly generated at the base station upon adding;
establish a backhaul connection between the small cell access point and a traffic interchange point for user plane traffic;
6. The small cell access point of claim 5, wherein the small cell access point is further configured to:
receive an association preparation message from the base station of the macro cell; and
