FIELD: physics, communication. ^ SUBSTANCE: invention is related to the field of wireless data transmission networks. Substance of invention consists in the fact that location identification (LI) and location detection (LD) are processed as separate and independent processes. LI is realised by means of the first set of network objects. Information on location may be placed into cash-memory for further disclosure to any number of applications. LD is realised by means of the second set of network objects. LI uses the first safety procedure for authentication, authorisation and receipt of the first session key used for LI. LD uses the second safety procedure for authentication, authorisation and receipt of the second session key used for LD. For mobile station under roaming, LI may be realised by means of service network, and LD may be realised by means of home network. ^ EFFECT: higher accuracy of location identification and provision of mobile stations with information on location. ^ 43 cl, 21 dwg, 4 tbl |
