摘要:
Locating satellites (e.g., GPS) are culled into a sub-plurality based largely on dwell time within an inverted cone above a relevant site in communication with a wireless device. A first inverted cone having a first base angle is defined above a first site, a second inverted cone having a second base angle is defined above a second site. If the second site is farther from an equator of Earth than the first site, then the second inverted cone is made to have a base angle larger than a base angle of the first inverted cone. If the first site is farther from the equator of Earth than the second site, then the first inverted cone is made to have a base angle larger than a base angle of the second inverted cone. The span of the inverted cone over the site closest to the equator may be limited.

A geometric shape (e.g., an inverted cone) is computed above a given ‘reference point’ defined from locations of cell sites OTHER than the cell site currently servicing a given wireless device, to provide a best-guess as to a near-future location of a mobile wireless device. Locating satellites (e.g., GPS) are culled into a preferred group and communicated to mobile devices within a particular region (e.g., serviced by a particular base station). The culled locating satellites may select those visible, or more preferably those locating satellites currently within a cone of space above the relevant base station are selected for communication by a mobile device within the service area of the base station. Thus, cell sites other than the one in use by the relevant wireless device may be specifically used to determine a reference point for culling the ephemeris information used to expedite Assisted GPS location determinations.

Locating satellites (e.g., GPS) are culled into a preferred group having a longest dwell time based on a time passing through an ellipsoid arc path through a cone of space, and communicated to mobile devices within a particular region (e.g., serviced by a particular base station). The locating satellites may be culled into a prioritized list. Each satellite is assigned an order of precedence based on a remaining dwell time within a primary inverted cone. Thus, a number ‘N’ of satellite's ephemeris data may be used, along with a preferred ‘order of precedence’ for secondary satellites to be used as backups as necessary.

The culled locating satellites may select those visible, or more preferably those locating satellites currently within a cone of space above the relevant base station are selected for communication by a mobile device within the service area of the base station. Alternatively, a minimum set of locating satellites may be selected based on, e.g., being not only within an arbitrary cone of space normal to the base station, but also projected to remain within that cone of space for the longest period of time, i.e., having the longest dwell time, based on a calculated ellipsoid arc path through a cone of space.

Locating satellites (e.g., GPS) are culled into a preferred group having a longest dwell time based on a time passing through an ellipsoid arc path through a cone of space, and communicated to mobile devices within a particular region (e.g., serviced by a particular base station). The culled locating satellites may select those visible, or more preferably those locating satellites currently within a cone of space above the relevant base station are selected for communication by a mobile device within the service area of the base station. The inverted cone of space may be defined for each antenna structure for any given base station, and each has 360 degrees of coverage, or less than 360 degrees of coverage, with relevant locating satellites. Thus, cell sites may be specifically used as reference points for culling the ephemeris information used to expedite Assisted GPS location determinations.
摘要:
A radar/laser emission detector is augmented with a cellular communications capability to provide the capability to share emission detection information amongst drivers to give other drivers even more advanced warning. A network of a plurality of cellular augmented radar/laser emission detector devices may be formed, each having the capability to source the location of radar or laser emission detections to others requesting access to such information, and each being warned when within a proximity of a recent radar or laser emission detection reported by at least one of the plurality of hybrid radar/laser detector devices. A local area, mobile area wireless network (MAWN) is formed in a cellular network to share radar/laser detection information among drivers. Mobile Position Centers (MPCs) are provided in ANSI-41 networks and Gateway Mobile Location Centres (GMLCs) (GSM networks), to determine other members that are proximate to a device that is detecting radar emission.
摘要:
A cellular alarm notification signal is received wirelessly from an alarming vehicle, and a position of a cellular transceiver of the alarming vehicle is requested and provided to police, security, emergency personnel, and/or surveillance cameras. A vehicle alarm notification is sent directly to the owner of a particular vehicle immediately upon alarm, or to the police, or to building security to dispatch an investigative team, or to a building surveillance company to activate or monitor a relevant security camera. In addition to the alarming status of the vehicle, the cellular alarm notification cellular call may provide a position of the alarming vehicle to the notified party, obtained through appropriate location services provided in a wireless system to satisfy requirements for responding in a personal emergency to a requesting public safety access point (PSAP).
摘要:
Cellular network technology is combined with a vehicle alarm to provide direct wireless notification of a vehicle alarm event over a cellular system to the owner or other interested party of a vehicle. A vehicle alarm notification is sent directly to the owner of a particular vehicle immediately upon alarm, or to the police, or to building security to dispatch an investigative team, or to a building surveillance company to activate or monitor a relevant security camera. In addition to the alarming status of the vehicle, the cellular alarm notification cellular call may provide a position of the alarming vehicle to the notified party, obtained through appropriate location services provided in a wireless system to satisfy requirements for responding in a personal emergency to a requesting public safety access point (PSAP). This real time alarm notification cellular call may be in lieu of, or additional to, sounding of an horn.
