The present invention relates to selection of sites of a communication system for measurement units that are for measuring a feature of wireless signals so that the location of a wireless station may be determined based on the measurement. Each measurement unit provides a measurement coverage. In the method a first set of information is defined, said first set relating to sites that are possible locations for the location measurement units and to the coverage provided by the site if it is provided with a measurement unit. A second set of information is defined that relates to signalling environment within the sites. Based on the defined first and second sets of information, a third set of information is defined, said third set associating each site with access entities of the communication system. Based on the third set of information, appropriate sites can be selected for the location measurement units.

Provision of location service apparatus

A telecommunications system comprises a first transmitter unit situated at a first, known location; a second transmitter unit situated at a second, unknown location; a first receiving unit at a third, known location arranged to receive signals from the first and second transmitter units; and a second receiving unit at a fourth, known location arranged to receive signals from the first and second transmitter units, wherein the said signals received by the first and second receiving units are usable to ascertain the location of the second transmitter unit.
