Abstract:
A centralized database system for use in a wireless location system that determines the geographical locations of mobile wireless transmitters, the wireless location system including signal collection systems, location processors for processing digitized RF data provided by the signal collection systems, and a centralized database system for managing resources in the wireless location system, the centralized database system comprising: a computer; a database; and a plurality of software processes for managing the wireless location system, providing interfaces to external users and applications, and storing location records and configuration information; wherein the wireless location system is capable of independently detecting and demodulating wireless transmissions, and a single wireless transmission can be detected and demodulated at multiple SCS's within the wireless location system; and wherein, when the wireless location system detects and successfully demodulates the same transmission multiple times at multiple SCS's, a plurality of prescribed criteria are used to select one demodulating SCS and antenna to use in the process of determining whether to trigger and initiate location processing, said plurality of criteria including the following criterion: an SCS/antenna collocated at a cell site to which a particular frequency has been assigned is preferred to another SCS/antenna.
