Beschreibung
Zusammenfassung:	FIELD: physics, communications. ^ SUBSTANCE: method involves a) checking information on home public land mobile network (PLMN) of target terminal (TT) in response to PL service query from user for TT PL in addressor gateway mobile terminal location centre (GMLC); b) checking information on guest network where TT is located, on the basis of home PLMN information, in home GMLC; c) defining whether guest network provides PLMN information assisting PL, using checked guest PLMN information; d) if guest PLMN does not provide PL assisting information, this information is deduced over home PLMN, using precise visit PLMN information on location; e) sending information assisting PL to TT; f) measurement of TT GPS pseudo-distance over TT, using PL assisting information, and measurement result transmission from TT to home PLMN; and g) calculation of TT position over home PLMN, using measured GPS pseudo-distance. ^ EFFECT: enhanced accuracy of location. ^ 48 cl, 15 dwg
