Title: (EN) GPS assistance messages in cellular communications networks and methods therefor
(ZH) 蜂窝通信网络中的GPS辅助消息及其方法
Abstract: front page image
(EN) GPS assistance message and data issue identifiers for transmission to GPS enabled mobile stations (104) in cellular communications networks (100) and methods therefor. The GPS data issue identifiers indicate whether GPS data, for example corresponding ephemeris and almanac data, stored at the mobile station (104) requires updating. In the exemplary 3rd generation (W-CDMA/UMTS) architecture, the GPS assistance message is a System Information Block (SIB), and the GPS ephemeris data identifier and corresponding satellite identifier is encoded in a value tag included in a Master Information Block (MIB).
