Embodiment Construction

[0038] FIG. 1 is a schematic block diagram of an exemplary cellular communication system in which enhanced Matrix positioning according to an embodiment of the present invention is implemented. The cellular communication system may for example be a conventional GSM system or a WCDMA system supplemented according to the invention.

[0039] The system includes a plurality of mobile terminals 110 , 120 and 130 . Mobile terminals 110, 120 and 130 may be conventional mobile terminals. At least some of them support Matrix. Each Matrix enabled mobile terminal 110 includes an OTD measurement component 111 adapted to perform OTD measurements and a positioning component 112 adapted to manage communications with a cellular communication network to support positioning of the mobile terminal 110 and other mobile terminals.

[0040] The system further includes a cellular communication network.

[0041] The cellular communication network comprises a plurality of base stations 201, 202, 20...

Abstract

A positioning of a mobile terminal is of a type, which comprises evaluating measurements on received signals by a plurality of mobile terminals 110,120,130. The signals are transmitted by a plurality of base stations 201-205 of at least one cellular communication network. For supporting a positioning of a mobile terminal, mobile terminals 110,120,130 that are suitable for performing such measurements are determined based on available location data for mobile terminals. The location data is available independently from a positioning of the indicated type.

Description

technical field [0001] The invention relates to a method for supporting positioning of a mobile terminal. The positioning is of the type comprising the evaluation of measurements by mobile terminals of received signals transmitted by base stations of at least one cellular communication network. The invention equally relates to a corresponding mobile positioning center, a corresponding cellular communication network, a corresponding cellular communication system, a corresponding software code and a corresponding software program product. Background technique [0002] A known positioning method that has been standardized by the 3rd Generation Partnership Project (3GPP) for the Global System for Mobile communications (GSM) is the Enhanced Observation Time Difference (E-OTD) method. In the 3GPP standard for Wideband Code Division Multiple Access (WCDMA) based systems, E-OTD is called Observed Time Difference of Arrival (OTDOA). The E-OTD / OTDOA method is also supported by the S...
