Abstract
The subject matter disclosed herein relates to a system and method for reducing an initial position uncertainty of a mobile station. In one example, although claimed subject matter is not so limited, a process to improve an initial position estimate comprises identifying the locations of a serving cell and at least one other landmark proximate to a receiver and determining an initial estimate of the location of the receiver based, at least in part, on the identified locations of the serving cell and the at least one other landmark.
Claims29
A method, comprising:
- identifying locations of a serving cell and at least one other landmark proximate to a receiver;
- determining an initial estimate of a location of said receiver based, at least in part, on said identified locations;
- and
- processing one or more satellite positioning system (SPS) signals received from one or more satellite vehicles (SVs) based, at least in part, on said initial estimate.
A method, comprising:
- estimating a location of a mobile station based, at least in part, on one or more satellite positioning system (SPS) signals received at said mobile station contemporaneously with communicating with a serving cell;
- and
- updating a location of at least one landmark other than said serving cell in a database maintained at said mobile station based, at least in part, on said estimated location.
An article comprising a storage medium comprising machine-readable instructions stored thereon which, when executed, are adapted to:
- identify locations of a serving cell and at least one other landmark proximate to a receiver;
- determine an initial estimate of a location of said receiver based, at least in part, on said identified locations;
- and
- process one or more satellite positioning system (SPS) signals received from one or more satellite vehicles (SVs) based, at least in part, on said initial estimate.
An article comprising a storage medium comprising machine-readable instructions stored thereon which, when executed, are adapted to:
- estimate a location of a mobile station based, at least in part, on one or more satellite processing system (SPS) signals received at said mobile station and contemporaneously communicate with a serving cell;
- and
- update a location of at least one landmark other than said serving cell in a database maintained at said mobile station based, at least in part, on said estimated location.
A mobile station, comprising:
- a receiver to receive one or more satellite positioning system (SPS) signals, said mobile station being adapted to:
- identify locations of a serving cell and at least one other landmark proximate to the receiver;
- determine an initial estimate of a location of said mobile station based, at least in part, on said identified locations;
- and
- processing the one or more SPS signals based, at least in part, on said initial estimate.
The mobile station of claim 29, wherein said mobile station is further adapted to determine uncertainty of location information associated with the serving cell and the at least one other landmark.
A mobile station, comprising:
- a receiver to receive one or more satellite positioning system (SPS) signals, said mobile station being adapted to
- estimate a location of the device based, at least in part, on the one or more signals received at said mobile station from the one or more GNSS transmitters contemporaneously with communicating with a serving cell;
- and
- update a location of at least one landmark other than said serving cell in a database maintained at said mobile station based, at least in part, on said estimated location.
