Abstract: Mobile LMUs can be used in a Wireless Location System to provide detection coverage in areas lacking adequate receiver coverage. The mobile LMUs can be used to detect the radio frequency (RF) transmissions from wireless handsets and devices over a period of time to permit determination of their location. The mobile LMU's time, position, and velocity is calculated and transmitted to a SMLC along with any transmissions received from wireless devices. The SMLC analyzes and resolves the Doppler component of the wireless device while compensating for the Doppler component of the mobile LMU. The position and velocity of the wireless device can be compared with real-time imagery taken by the mobile LMU platform to accurately determine the location of the wireless device. To enhance the mobile LMU's ability to detect a signal of interest, which may be very weak and/or corrupted by noise, a process may be employed whereby the low power mobile terminals' signals are received at receiving sites and stored in memory.

Abstract: Method and systems are employed by a wireless location system (WLS) for locating a wireless device operating in a geographic area served by a wireless communications system. An exemplary method includes monitoring a set of signaling links of the wireless communications system, and detecting at least one predefined signaling transaction occurring on at least one of the predefined signaling links. Then, in response to the detection of the at least one predefined network transaction, at least one predefined location service is triggered.

Abstract: A centralized database system is used 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 includes 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.

Abstract: In multi-user operating systems, set-up files that are present locally have to be processed each time a user logs in at a computer, in order to undertake settings at the computer which optimally configure the further operating of the user using his user programs. If an update of a user program is now fed in, it is also necessary to change the associated set-up file. This change to a set-up file is now carried out on a net-wide basis and automatically on the basis of the set-up mechanism.

Abstract: A system and method provides multiple sequential call-forwarding transfers to a sequence of C-numbers within a conventional cellular radio communications system by providing a unique identifier for each call and enabling a home location register (HLR) to coordinate and disseminate multiple calls made to the same mobile station. The HLR stores, within a subscriber database, a sequence of C-numbers on a call-forwarding priority list to which calls are to be forwarded in the event a call cannot be completed to the mobile station. Each C-number is associated with sets of unique identification numbers and time stamps. When an incoming call is received at an originating mobile switching center (MSC), a transfer-to-number request message, containing a unique number identifying the request, is transmitted from the MSC to the HLR containing the subscriber database. In response, the HLR analyzes the request, searches the C-number priority list, and transmits to the MSC, the optimum C-number for completing the call.
