Data transmission for mobile wireless communication devices

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.

1 . A method in a mobile wireless communication station operating in a first data rate mode and a second data rate mode, comprising: 
 predicting when the mobile wireless communication station transitions between the first data rate mode and the second data rate mode;    requesting data from a network prior to transitioning between the first data rate mode and the second data rate mode wherein said first data rate mode includes a higher data rate than said second data rate mode; and    receiving data from the network, at said higher data rate via said first data rate mode prior to the mobile wireless communication station transitioning between the first data rate mode and the second data rate mode in response to the request.
