A method for improving accuracy of estimation of a location of a mobile device, said mobile device registered with a network of a first operator, which comprises: i) triggering the mobile device to measure RF signals broadcasted by one or more base stations of other operator(s); ii) using said measured RF signals in estimating the location of the mobile device. A method is also provided for determining by the mobile network of a first operator the location of a base station belonging to the network of a second operator, which comprises: - by a network entity of the first operator, collecting a plurality of measurements of at least one RF frequency of the second operator reported by at least one mobile device registered with the mobile network of the first operator whose location is known or determinable using a location method; and - estimating the location of said base station belonging to the network of a second mobile operator from said measurements of at least one RF frequency.
