Abstract:
A method and apparatus of optimizing transitioning between EVDO and CDMA 1X systems in a hybrid access terminal, the method having the steps of: preventing a reconnect data call from being sent from the hybrid access terminal. The preventing step including checking whether a transition between an EVDO and a CDMA 1X system is successful; and if not blocking the data call, and/or checking whether an EVDO received signal strength indication is greater than or equal to a receiver sensitivity on the hybrid access terminal; and if yes, allowing the hybrid access terminal to connect to the EVDO system, and/or delaying a connection timer for connecting to the EVDO system and/or applying fast dormancy to the hybrid access terminal in an EVDO state.
