ABSTRACT:
An Applications Processor (14) including a centralized database system is used in a wireless location system (WLS). The APs14may be used to manage resources in the WLS, including signal collection systems (SCSs10) and TDOA location processors (TLPs12). Each AP14contains a database containing triggers for the WLS. The WLS can be programmed to locate only certain pre-determined types of transmissions. When a transmission of a pre-determined type occurs, then the WLS is triggered to begin location processing. Each AP14also contains applications interfaces that permit a variety of applications to securely access the WLS. These applications may access location records in real time or non-real time, create or delete certain types of triggers, or cause the WLS to take other actions. Each AP14is also capable of certain post-processing functions.
