Abstract:
1. A method of operating a radio access network comprising: using a resident radio receiver at a femto radio base station to acquire, over a radio interface, system information broadcast in a radio access network by scanning a surrounding macro coverage area of the femto radio base station for obtaining cell identify information for detected cells; using at least part of the system information for building, at the femto radio base station, a neighbor data structure comprising information for neighboring cells and adding the cell identity information to the neighbor data structure; measuring a signal strength for each detected cell to the neighbor data structure; adding a measured value of the signal strength for each detected cell to the neighbor data structure; transmitting the neighbor data structure, including the cell identity information and measured values for each detected cell, from the femto radio base station to a network node other than the femto radio base station and using the neighbor data structure for building a neighbor list at the other node; transmitting the neighbor list to the femto radio base station that measured the signal strength for the detected cells; and transmitting the neighbor list from the femto radio base station over the radio interface to a user equipment unit served by the femto radio base station.
