Abstract:
A method for spatially locating a mobile station in a cell of a mobile radio network, said cell being of the type controlled by a base station with an omnidirectional antenna, said cell being divided into a plurality of angular sectors centered on said base station, said method comprising:allocating a separate location signal element to each angular sector;said mobile station sending a signaling packet carrying all location signal elements for said cell;for each angular sector, modifying the signaling packet sent by the mobile station before it is received by said omnidirectional antenna, said modifying being specific to said each angular sector;determining, from the modified signaling packet received by said omnidirectional antenna, the modification made; anddeducing, from said modification made, the angular sector in which said mobile station is located.
