Abstract
A device, method and system are provide which permits the methodology used to make the position determination to change dynamically in connection with achieving a position fix of a desired accuracy.
Claims20
A method of obtaining a position of a mobile station comprising:
- (a) determining the position of the mobile station using a first scheme of position determination, wherein the first scheme of position determination is based upon GPS, trilateration, server assisted GPS, cell identification, enhanced signal strength, angle of arrival, forward link trilateration, advanced forward link trilateration, fingerprinting or a combination thereof;
- and
- (b) if the determining does not yield an acceptable position result, repeating said determining using at least one further scheme of position determination different from said first scheme in at least one repetition until (i) a repetition returns an acceptable position result or (ii) a threshold number of available position-determining schemes have been used.
An apparatus configured to obtain a position of a mobile station comprising:
- means for determining the position of the mobile station using a first scheme of position determination, wherein the first scheme of position determination is based upon GPS, trilateration, server assisted GPS, cell identification, enhanced signal strength, angle of arrival, forward link trilateration, advanced forward link trilateration, fingerprinting or a combination thereof;
- and
- means for repeating said determination if the determination does not yield an acceptable position result using at least one further scheme of position determination different from said first scheme in at least one repetition until (i) a repetition returns an acceptable position result or (ii) a threshold number of available position-determining schemes have been used.
An apparatus configured to obtain a position of a mobile station comprising:
- a processor configured to:
- determine the position of the mobile station using a first scheme of position determination, wherein the first scheme of position determination is based upon GPS, trilateration, server assisted GPS, cell identification, enhanced signal strength, angle of arrival, forward link trilateration, advanced forward link trilateration, fingerprinting or a combination thereof;
- and
- repeat said determination if the determination does not yield an acceptable position result using at least one further scheme of position determination different from said first scheme in at least one repetition until (i) a repetition returns an acceptable position result or (ii) a threshold number of available position-determining schemes have been used.
1 more element
A non-transitory computer-readable medium containing instructions stored thereon, which, when executed by an apparatus configured to obtain a position of a mobile station, cause the apparatus to perform operations, the instructions comprising:
- at least one instruction to determine the position of the mobile station using a first scheme of position determination, wherein the first scheme of position determination is based upon GPS, trilateration, server assisted GPS, cell identification, enhanced signal strength, angle of arrival, forward link trilateration, advanced forward link trilateration, fingerprinting or a combination thereof;
- and
- at least one instruction to repeat said determination if the determination does not yield an acceptable position result using at least one further scheme of position determination different from said first scheme in at least one repetition until (i) a repetition returns an acceptable position result or (ii) a threshold number of available position-determining schemes have been used.
