Abstract

A method and apparatus to transmit data between a communication network and a mobile station just before prior to the mobile station switching from a fast data rate mode, such as digital mode, to a slow data rate mode, such as analog mode. The mobile station requests or the communication network transmits data prior to the mobile station entering the slow data rate mode, therefore eliminating the need to transmit data over a slow data rate mode, such as analog mode.

Claims

1. A mobile wireless communication station that operates in a first data rate mode and second data rate mode, comprising:

a processor for predicting when the mobile wireless communication station transitions between the first data rate mode and the second data rate mode;

a transmitter coupled to the processor, the transmitter for transmitting data before the mobile wireless communication station transitions between the first data rate mode and the second data rate mode;

a means for requesting data from a cellular communication network prior to the mobile communication station transitioning between the first data rate mode and the second data rate mode;

a means for requesting Global Positioning Satellite system data from the cellular communication network before transitioning; and

a means for requesting ephemeris data from the cellular communication network before transitioning.

2. The mobile wireless communication station of claim 1, further comprising a means for receiving ephemeris data from the cellular communication network before transitioning.
