Traffic management in a hybrid femtocell/WLAN wireless enterprise network
A hybrid network controller may determine and/or communicate traffic management information for enabling setup and/or handoff of call and/or communication session among femtocells, access points and/or end-point devices. Traffic management information may comprise set-up instructions, handoff instructions, transmit power, neighbor list information, signal quality thresholds, frequency assignments, transmission time, code assignments and/or antenna pattern assignments. The hybrid network controller and/or an end-point device may control handoffs between a communication device external to the communication system and the femtocells, access points and/or end-point devices. Received signal strength, interference levels, SNR, signal path delay, power consumption, traffic loads, bandwidth usage and/or radio resource availability may be monitored and/or analyzed by the hybrid network controller. The hybrid network controller may assign time slots, codes, antenna patterns as well as a serving femtocell and/or AP for a set up and/or a handoff. The information may be communicated via wired, optical and/or wireless interfaces.
