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.
