Abstract: A method for use in a mobile communication system for estimating the location of a target mobile station (MS), N, which includes receiving signals from the target MS at a plurality of receivers 1, 2, 3 in different locations and calculating the location of the target MS from information obtained from the received signals, wherein at least one of the receivers is a searching MS 1 and wherein the calculation of location is carried out by the searching MS. The method may involve the target MS and the searching MS or MSs communicating by a direct mode of operation (DMO) link. The searching MSs may conveniently have GPS attachments 1a, 2a, 3a. A mobile station which may be used as the target MS or as a searching MS is also disclosed.
