Abstract: PROBLEM TO BE SOLVED: To provide a wireless global positioning system that can decide a position of a wireless mobile communication device without GPS capability without disturbing reception of a satellite signal. SOLUTION: The wireless positioning system determines the location of a wireless mobile communication device from reliable position measurements and wireless network downlink measurements. The wireless network downlink measurements obtained are then used in conjunction with a database for pattern matching or contour matching. The difficulty of building and maintaining that database is alleviated by using those network downlink measurements associated with the reliable position measurements to populate the database, such as GPS measurements or those obtained through enhanced based positioning technique (EOTD). The increased database accuracy subsequently improves the quality of position location measurements from the wireless network.

Abstract: PROBLEM TO BE SOLVED: To obtain an auxiliary system which mostly prevents costs and limitation in a conventional system, which decides the position of a wireless terminal, which is low-cost as compared with a conventional wireless terminal, which can receive a weak signal as compared with the conventional wireless terminal, and which realizes the wireless terminal capable of deciding the position quickly as compared with the conventional wireless terminal. SOLUTION: A task of signal acquisition and signal processing which are required by a conventional wireless terminal is divided into a wireless terminal 501 and an auxiliary system 505. Especially, a condition which is required normally from the conventional wireless terminal is shifted to the auxiliary system 505. The auxiliary system 505 provides information useful for the wireless terminal 501 through a wireless communication link 504. The auxiliary system 505 acquires information regarding the astronomical ephemeris of, a satellite, it processes the information partially, and it transmits the information to the wireless terminal 501 in a form which is useful for the wireless terminal 501.

Abstract: PROBLEM TO BE SOLVED: To realize a wireless communication system that uses position information to transfer specific information to a person carrying a mobile unit. SOLUTION: The wireless communication system has a controller 301 that receives information denoting the position of a wireless communication device (mobile unit) and a memory that stores information identifying the mobile unit and instruction information corresponding to the information. Upon the receipt of information denoting meeting the position requirement of the mobile unit geographically relating to a remote position (e.g. the position of the mobile unit is within a distance designated from the remote position), the controller 301 outputs information to the mobile unit on the basis of the stored instruction information. The controller 301 compares the position information of the mobile unit with the stored position information of the remote position so as to discriminate when the mobile unit meets the geographical relation.

Abstract: PROBLEM TO BE SOLVED: To provide a system and a method that executes actions on the basis of position. SOLUTION: The wireless electrical communication system uses a location or position information, to start action on behalf of a person who is moving. Upon the receipt of positional information of a wireless mobile body, the system compares it with positional information storing the remote position such as that of a residence or the like. When the moving person approaches the residence and reaches a certain distance from the residence, the system transmits a signal to a controller in the residence, to perform the action or instructs to perform the action.

Abstract: A wireless terminal and auxiliary system are disclosed that enable the wirel ess terminal to determine its location based on signals transmitted from navigation satel lites. In particular, the tasks of signal acquisition and signal processing required of a wireless terminal in the prior art are divided between the wireless terminal and the auxiliary system in ac cordance with the illustrative embodiment. The auxiliary system assists the wireless terminal by acquiring information about the satellites' ephemerides, by partially processing it an d by transmitting the partially processed information to the wireless terminal in a form that is u seful to the wireless terminal. The wireless terminal then uses the partially processed informatio n from the auxiliary system to assist the wireless terminal in acquiring the ranging signals from the navigation satellites quickly and when they are weak.

Abstract: The invention is directed towards a method for estimating a PRN synchronization and Doppler shift of a satellite signal at a reference location within a cell and sector of where a wireless terminal or WAG client is located. The estimates are based on information conveyed by a GPS signal acquired by an auxiliary system or WAG server, which may be at a location different from the wireless terminal or WAG client. The PRN synchronization and Doppler shift estimates are also based on some reference time, which is a time that is sufficiently far into the future to allow the WAG client to demodulate and decode the PRN synchronization and Doppler shift estimates from an assisting message transmitted by the WAG server and to use such estimates to acquire GPS signals, wherein the assisting message indicates the PRN synchronization and Doppler shift estimates.

Abstract: A wireless telecommunications system uses location or position information o f a wireless mobile unit to initiate the sending of location-specific informatio n to travelers. As position information is received, it is compared to prestored position information of a remote location, such as an airport. As the traveler approaches the remote location, and gets within a certain distance the remote location, information such as airline arrival information is retrieved and sent to the wireless mobile unit of the travele r. Thus, useful information tied to the position of the wireless mobile unit, such as airlin e or traffic information for example, is obtained.
