Abstract
Disclosed is a method of calculating a geospatial position by a mobile device by monitoring with the mobile device a first control channel from a first cell of a cellular communications system; monitoring with the mobile device a second control channel from a second cell of the cellular communications system at the same time as the first cellular control channel; receiving with the mobile device a first correction value sent over the first control channel; receiving with the mobile device a second correction value sent over the second control channel; receiving with the mobile device a signal from a global navigation satellite system; calculating with the mobile device the geospatial position based upon the signal from the global navigation satellite system and at least one of the first correction value and the second correction value.

21. 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; determining from a past observation of a message on the first control channel of the first cell of the cellular communications system, 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; receiving with the mobile device the first correction value sent over the first control channel at the first time; receiving with the mobile device the second correction value sent over the second control channel at the second time; 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. - View Dependent Claims (22, 23, 24, 25, 26, 27)

28. A mobile device for receiving geospatial positioning information, the mobile device comprising:
-
a processor configured by a non-transitory machine readable medium to perform operations of; monitoring with a mobile device a first control channel from a first cell of a cellular communications system; determining from a past observation of a message on the first control channel of the first cell of the cellular communications system, 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; receiving with the mobile device the first correction value sent over the first control channel at the first time; receiving with the mobile device the second correction value sent over the second control channel at the second time; 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. - View Dependent Claims (29, 30, 31, 32, 33, 34)

35. A non-transitory machine-readable medium that stores instructions which when performed by a machine, cause the machine to perform operations comprising:
-
monitoring with a mobile device a first control channel from a first cell of a cellular communications system; determining from a past observation of a message on the first control channel of the first cell of the cellular communications system, 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; receiving with the mobile device the first correction value sent over the first control channel at the first time; receiving with the mobile device the second correction value sent over the second control channel at the second time; 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. - View Dependent Claims (36, 37, 38, 39, 40)
