摘要： A position determination method in a mobile unit uses the telephone number of a wireline telephone and a reverse phone-book operation for determining the location of a mobile unit. In one embodiment, a method for determining the location of a mobile unit using a telephone number of a wireline telephone in the vicinity of the mobile unit includes receiving at a server the telephone number transmitted from the mobile unit using wireless communication through a data network, retrieving an address associated with the telephone number in the server, and retrieving a location of the mobile unit based on the address. The server may provide location-relevant information using the location information. The system and method of the present invention provides a low cost solution to position determination in wireless hand-held devices and can be used to supplement the conventional positioning systems.

摘要： Presented is a method and apparatus for selectively using a local area network and a wide area network in a hybrid network system. A mobile unit receives information, for example positioning information from Global Positioning System satellites. Upon receiving information, the mobile unit associates the information with either a WAN category or a LAN category. Information in the WAN category are transmitted to a WAN computer via a wide area network and information in the LAN category is transmitted to a LAN computer via a local area network. A user may specify which network he wants to use. Alternatively, the mobile unit may be programmed with criteria by which it can categorize the received information. The WAN computer and the LAN computer may be coupled, allowing a user to access the LAN computer via the WAN or the WAN computer via the LAN.

摘要： An in-vehicle system comprises a location unit, a frequency selection unit, and a receiving unit. Frequency tuning data is loaded into the selection unit. The frequency tuning data includes a radio signal reception area for each unique frequency in the tuning data. The location unit determines the system location and passes the location information to the frequency selection unit. The selection unit selects tuning data for a particular frequency having a signal reception area that encompasses the present vehicle location, and passes the selected data to the receiving unit. The receiving unit uses the selected tuning data to tune the radio signal.

摘要： A positioning information distribution system for distributing positioning information through a data network is described. In one embodiment, the system distributes satellite information from a global positioning system (GPS). The system includes an information processing station connected to a data network accessible by wireless communication, a receiving station including a GPS receiver, and a mobile unit including a GPS receiver and a wireless receiver. The information processing station collects GPS satellite information from the receiving station and transmits the satellite information to the mobile unit using wireless communication. Alternately, a network of receiving stations are provided. The mobile unit can obtain the satellite information from the information processing station for determining its measured position, even when the mobile unit is roaming in an urban area and is not able to observe the GPS satellites for the lengthy observation period needed to acquire the satellite information itself.

Under one method, a server that is accessible over the wide area network through a wireless communication link is provided. Then, in a vehicle, an apparatus is provided to collect, over a data bus in the vehicle, data relating to an operation of the vehicle. The data received from the data bus is then communicated to the server over the wireless communication link. Based on the data received at the server, the maintenance-related services is then initiated. The operation data of the vehicle can be collected from various subsystems of the vehicle, such as a brake sub-system, an engine sub-system and various sensors located at various subsystems of the vehicle. Under one mode of operation, the data collected from these subsystems are reported to the server at pre-determined time intervals. In one embodiment, the apparatus of the invention includes a positioning apparatus for determining a location of said vehicle from received ranging signals. Such signals can be received from a global position system (GPS) or a ranging system based on triangulation, such as those used in cellular telephone systems.

摘要： System and methods for determining and disseminating current traffic information and/or route information are presented. For example, in accordance with one embodiment of the present invention, traffic condition information is collected from mobile units that provide their location or position information. The traffic condition may be determined, for example, based on the difference between the velocity of each mobile unit and the speed limit corresponding to their location. Furthermore, the fastest routes between two locations may be determined and provided based on historical and/or current conditions and provided to a mobile unit. In accordance with another embodiment of the present invention, route information may be utilized to determine whether a mobile unit (e.g., associated with a vehicle) is allowed or prohibited from traveling along a certain route.
