Claim of US Patent No. 9,338,133

1. One or more tangible non-transitory computer-readable media having computer-useable instructions embodied thereon for a
method of selecting an optimum security gateway, the method comprising:
connecting to a default security gateway;
locating appropriate macrocells based on a discovery function executed by the default security gateway;
determining the best security gateway for the appropriate macrocells, wherein the best security gateway is identified based
on the distance from a picocell connected to the default security gateway having backhaul traffic to offload to the appropriate
macrocells connected to the best security gateway;

disconnecting from the default security gateway;
connecting to the best security gateway for the appropriate macrocells;
updating a routing table based on the best security gateway selected for the picocell;
selecting at least two or more macrocells as the appropriate macrocells for the best security gateway; and
altering available capacity for the selected macrocells upon receiving the backhaul traffic, wherein the backhaul traffic
is distributed among two or more macrocells associated with the best security gateway but the default security gateway is
selected as the best security gateway if the available macrocells are unable to offload the backhaul traffic.
