Title:
強化されたセルアイデンティティの適応的な測位における適応的なポリゴンの計算
Document Type and Number:
Japanese Patent JP5102346
Kind Code:
B2
Abstract:
A method for provision of position determination assisting data in a cellular communication network comprises establishing (204) of a cell relation configuration for a user equipment. The cell relation configuration comprises cell identities of cells, in which signals fulfill a specific radio condition criterion when received. The method further comprises performing (206) of a high-precision position determination for the user equipment. The establishing and performing steps (204, 206) are repeated a plurality of times. Positioning points belonging to the same cell relation configuration are clustered (208) and a polygon is associated (212) with each result cluster. The association (212) comprises encompassing of a result cluster by a polygon, altering of the polygon corners along defined paths to improve a predetermined criterion, and counteracting that polygon corners are gathering at a minor portion of a circumference. The method finally comprises creating (212) of position determination assisting data comprising a relation between the cell relation configurations and the polygon.
