Abstract
The invention relates to a method for supporting location determination of a mobile station, in which method location data are stored in and deleted from a memory, each location data item describing the location of the mobile station measured at a given measuring moment. Furthermore, in the method, a distance parameter and/or a target level corresponding to the distance parameter is determined at least for some of the stored location data; and deletion of the location data is at least partly based on the distance parameter and target level.
Claims17
A method for managing location measurement data, the method comprising:
- for at least one mobile station, determining and maintaining in a memory, multiple mobile-specific location records such that the multiple mobile-specific location records indicate a location history of the mobile station in question;
- for each of the mobile-specific location records, assigning a corresponding optimization parameter;
- using the assigned optimization parameters to choose which mobile-specific location records of the mobile station are to be deleted from the memory and deleting the chosen mobile-specific location records;
- wherein the optimization parameter comprises at least one of:
- a distance parameter that favours weighted deletion of mobile-specific location records corresponding to locations between which the mobile station has moved least;
- and
- an age parameter that favours weighted deletion of old mobile-specific location records.
Equipment for managing location measurement data, the equipment being arranged to determine and maintain in a memory multiple mobile-specific location records for at least one mobile station such that the multiple mobile-specific location records indicate a location history of the mobile station in question, wherein the equipment is further arranged to assign a corresponding optimization parameter for each of the mobile-specific location records and use the assigned optimization parameters to choose which mobile-specific location records of the mobile station are to be deleted from the memory and delete the chosen mobile-specific location records, wherein the optimization parameter comprises at least one of a distance parameter that favours weighted deletion of mobile-specific location records corresponding to locations between which the mobile station has moved least, and an age parameter that favours weighted deletion of old mobile-specific location records.
