In a cellular mobile telecommunication system there is possibility to make change of base of calls in progress to other mobile telephone networks. The invention deals with a method to collect information necessary to make possible to make a change of base. Said information is collected without aid from the network operator in the second mobile telephone network. Necessary information is collected from the second mobile telephone network by measuring of signals. The following processing of the information aims at deciding which base stations in this second network which are so located that it is possible to make change of base to them. This means in most cases which base stations which, in the measured area, have sufficient signal strength to constitute candidate for change of base from base station in the delivering network. |
