US 7,720,482 B2 · Method and apparatus for transitioning between EVDO and CDMA 1X systems using redundant data call blockings

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.

Dependent claims

A method in a hybrid access terminal, including a processor and associated memory storing executable computer code, for optimizing transitioning between Evolution Data Only (EVDO)and Code Division Multiple Access (CDMA) 1X systems in a hybrid access terminal comprising the steps of:

a. executing computer code in the processor to detect a transition between Code Division Multiple Access (CDMA) 1X and EVOLUTION DATA ONLY (EVDO);
b. executing computer code in the processor to check whether the transition between the CDMA 1X and EVOLUTION DATA ONLY (EVDO) system is successful;
and if not,
c. executing computer code in the processor to block a reconnect data call from the hybrid access terminal.
