Abstract: 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.

Abstract: A technique evaluates overlapping request intervals, and from them determines a temporal reporting interval that satisfies requirements for all that overlap. The temporal reporting interval represents a temporal trigger used to best support multiple triggers on the same target, without modification or support by the target mobile. Disclosed embodiments relate to an example of location requests wherein multiple users, by chance, request location triggered services on the same target mobile during the same time period. To minimize the usage of mobile and network resources, the present invention reduces the number of active triggers on a target mobile subjected to multiple requests (e.g., location requests from multiple tracking applications).

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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. 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.
