Abstract
A method and system is disclosed for locating a mobile radio terminal in a radio communications network. The method makes use of additional positional constraints provided as a result of unreported cells. In one form of the invention, a likely reason for a particular cell not being reported is determined and an associated probability term is determined for use in a position location model. The invention also relates to a system for implementing the method.
Claims28
A method for locating a mobile radio terminal in a radio communications network, the method comprising:
- identifying a set of cells about an approximated location of the mobile radio terminal;
- identifying at least one cell in the identified set that is unreported by the mobile radio terminal, the remaining cells in the identified set being reported;
- and determining a location of the mobile radio terminal on the basis of the at least one unreported cell.
A system for locating a mobile radio terminal in a radio communications network, the system comprising:
- means for identifying a set of cells about an approximated location of the mobile radio terminal;
- means for identifying at least one cell in the set of identified cells that is unreported by the mobile radio terminal, the remaining cells in the identified set being reported;
- and means for determining a location of the mobile radio terminal on the basis of the at least one unreported cell.
