摘要
A method of using the existing radio resources to automatically determine the current cellular topology is described. Wireless base stations are placed into a mode where they can transmit a signal which can be received by all of the base stations in range of the transmitting base station. Each base station in the system serially broadcast a signal which is received by all other base stations within the range of the transmitting base station. Each of the receiving radios determines the RSSI (Received Signal Strength Indication) at which they received the transmitted signal. The RSSI values are used to determine which base stations are physically co-located into cells and then determine the relative locations of the cells to each other. A method is also described by which the wireless system monitors the mobility traffic of subscribers and makes use of this information to improve the operation of the system. As the user makes use of the mobility features of the system by making and receiving wireless calls, the mobility patterns of the users are tracked and fed into an algorithm which determines and updates to the central wireless configurations. Hence, over time the system is able to determine which cells are more likely to be involved in handover situations.
