Abstract
Systems and methods are provided for positioning determination for mobile devices. A system includes: a database configured to store positioning data associated with one or more base stations in a network, and a data management component configured to compare the parameters with one or more parameter thresholds, and update the positioning data based at least in part on the comparison of the parameters and the parameter thresholds. The updated positioning data is used for positioning determination of a mobile device.
Claims20
A system for positioning determination for mobile devices, the system comprising:
- a database configured to store positioning data associated with one or more base stations in a network;
- and
- a data management component configured to compare the parameters with one or more parameter thresholds and update the positioning data based at least in part on the comparison of the parameters and the parameter thresholds;
- wherein the updated positioning data is used for positioning determination of a mobile device.
A system for positioning database management, the system comprising:
- a database configured to store positioning data, the positioning data associating position information of a location with an identifier of a wireless station for providing wireless connection at the location and a signal characteristic received at the location;
- and
- an apparatus configured to:
- determine whether an update condition for triggering an update for a group of the positioning data associated with a wireless station is satisfied;
- apply, when the update condition is satisfied, one or more cluster calculations to select one or more clusters that contain junk data to be removed from the group of the positioning data in order to increase the accuracy of positioning data;
- and
- store the updated positioning data;
- wherein the group of the updated positioning data is used for a server-based positioning system to determine the position information of a wireless device.
A method for positioning database management, the method comprising:
- determining whether an update condition for triggering an update for a group of the positioning data associated with a wireless station is satisfied, the positioning data associating position information of a location with an identifier of a wireless station for providing wireless connection at the location and a signal characteristic received at the location;
- applying, when the update condition is satisfied, one or more cluster calculations to select one or more clusters that contain junk data to be removed from the group of the positioning data in order to increase the accuracy of positioning data;
- and
- storing the updated positioning data;
- wherein the group of the updated positioning data is used for a server-based positioning system to determine the position information of a wireless device.
A system for determining a position information of a wireless device, the system comprising:
- one or more processors configured to:
- receive a position request from a wireless device that receives an identifier and a specific characteristic of a wireless signal from a specific wireless station;
- identify the specific wireless station using the identifier to retrieve a group of positioning data from a database;
- select a subset in the group of positioning data using the specific characteristic;
- and
- determine position information of the wireless device using the selected subset of positioning data.
