Patent number: 7715849Abstract: The invention proposes a method for locating a network element, comprising the steps of obtaining (S1) the coordinates (xS, yS) of a second network element (BTS) to which the first network element (MS) is connected or attached; detecting (S2) a serving area (S), which is served by the second network element (BTS); detecting (S3) a propagation delay of the first network element with respect to the second network element (BTS); determining (S4) a propagation delay depending area (C), which is an area having a distance to the second network element (BTS) based on the propagation delay and a width based on the propagation delay; and forming (S5) an intersection area (I) of the serving area (S) and the propagation delay depending area (C); wherein a location estimate of the first network element (MS) is determined (S6) from the intersection area (I). Thus, an uncertainty area where a first network element is located can be reduced and the location accuracy can be improved.Type: GrantFiled: February 28, 2001Date of Patent: May 11, 2010Assignee: Nokia CorporationInventors: Maurizio Spirito, Ville Ruutu

Patent number: 7706814Abstract: The method generates a location estimate for a mobile station in a wireless communications network. The method includes receiving first measurement data relating to at least one radio link between the mobile station and a first site, and provides a first distance estimate of the mobile station from the first site based on the first measurement data. Second measurement data is received, relating to at least one radio link between the mobile station and a second site and provides a second distance estimate of the mobile station from the second site. First and second intersection points are determined between a circle centered at the first site of a radius corresponding to the first distance estimate, and a circle centered at the second site of the radius corresponding to the second distance estimate. The first and second intersection points lie on opposite sides of a line passing through the first and second sites.Type: GrantFiled: August 13, 2004Date of Patent: April 27, 2010Assignee: Nokia CorporationInventors: Eero Sillasto, Maurizio Spirito

Patent number: 7680501Abstract: A method of providing a location estimate for a mobile station in a wireless communications network. The method of providing the location estimate includes implementing, in parallel, a plurality of different location estimate generation methods, each location generation method generating a location estimate. The method of providing the location estimate also includes selecting one of the location estimates based on predetermined criteria.Type: GrantFiled: December 1, 2004Date of Patent: March 16, 2010Assignee: Nokia CorporationInventors: Eero Sillasto, Maurizio Spirito

Patent number: 7019693Abstract: The altitude of a communications device, which communicates with a communications system via at least one antenna, is estimated. The altitude estimation is based at least on altitude information of said at least one antenna. The altitude estimate of the communications device may be based on a two-dimensional location estimate for the communications device and on information representing three-dimensional location of said at least one antenna of said communication system. The two-dimensional location estimate and the altitude estimate may be sent to the communications device as location assistance information.Type: GrantFiled: February 24, 2004Date of Patent: March 28, 2006Assignee: Nokia CorporationInventor: Maurizio Spirito

Publication number: 20050255855Abstract: A method of generating a location estimate for a mobile station in a wireless communications network. The method includes receiving first measurement data relating to at least one radio link between the mobile station and a first site and using said first measurement data in a location calculation method with radio network data to provide a first preliminary location estimate. The method also includes receiving second measurement data relating to at least one radio link between the mobile station and a second site and using in the location calculation method with radio network data to provide a second preliminary location estimate. The method further includes determining the location estimate as the weighted mass center of the first and second preliminary location estimates.Type: ApplicationFiled: January 10, 2005Publication date: November 17, 2005Inventors: Maurizio Spirito, Eero Sillasto
