Claim Text:
1. A method of receiving geospatial positioning information, the method comprising: monitoring with a mobile device a first control channel from a first cell of a cellular communications system from a first base station; determining from information in a broadcast message on the first control channel of the first cell of the cellular communications system from the first base station, a first time that a first correction value will be sent from the first control channel and a second time that a second correction value will be sent from a second control channel from a second cell of the cellular communication system from a second base station; receiving with the mobile device the first correction value sent over the first control channel at the first time, the first correction value calculated by a first correction calculation device physically located at a first site of the first base station; receiving with the mobile device the second correction value sent over the second control channel at the second time, the second correction value calculated by a second correction calculation device physically located at a second site of the second base station; receiving with the mobile device a signal from a global navigation satellite system; and calculating with the mobile device a geospatial position of the mobile device based upon the signal from the global navigation satellite system and at least one of the first correction value and the second correction value.
