FIELD: technology for determining position of mobile stations in cell communication networks, in particular, auxiliary messages of global positioning system for mobile stations, transferred to cell phones, and methods for realization of same.
SUBSTANCE: identifiers of GPS ephemerid data output indicate whether renewal of GPS data is needed, for example, of appropriate ephemerid data and anthology data, stored in mobile station (104). In architecture of wideband multi-access with code division of channels of universal mobile telecommunication system (W-CDMA/UMTS) of 3-d generation, auxiliary GPS message is represented by a block of system information (SIB), and GPS ephemerid data identifier and appropriate satellite identifier are encoded in value sign, included in setting information block.
EFFECT: decreased power consumption of mobile stations, resulting in increased resource of same.
