| 1. A method for controlling a wireless communications system, comprising:
selecting a plurality of base station routers, at least one of said base station routers being adapted to operate as a primary
foreign agent and at least one of said base station routers being adapted to operate as a secondary foreign agent, wherein
the secondary foreign agent is capable of communicating with a mobile device and the primary foreign agent is capable of communicating
with a network, wherein selecting a plurality of base station routers further comprises forming an active network set from
the selected base station routers, periodically adding a base station router to the active network set based on a characteristic
of communications between the base station router and the mobile device, and periodically removing a base station router from
the active network set based on a characteristic of communications between the base station router and the mobile device;
selecting one of said base station routers to operate as the primary foreign agent; and
communicating to at least a portion of the base station routers information indicative of the base station router that is
selected to operate as the primary foreign agent.
