摘要
Abstract
A method for efficiently transmitting location assistance information to an MS (mobile station) over a control channel with minimal impact on the capacity of the control channel. A location server provides a difference between satellite positions that have been computed using Almanac data and Ephemeris data. Sending only the difference between the positions and satellite clock corrections computed using the two different data types. The total amount of information to be transmitted to a MS is significantly reduced. Furthermore, by providing rate of change information, the method allows the location assistance information to remain valid for a relatively long time after it has been received by the MS.关键词
