Abstract:
1. A method of wireless communications, comprising: determining whether one or more fallback conditions are present before or during establishing a data session with a first data service via a first data system; and prohibiting further attempts to establish a data context to access the first data service via the first data system based on the determination of the presence of at least one of the one or more fallback conditions; wherein one of the one or more fallback conditions indicates an occurrence of a hard fallback failure or an occurrence of a soft fallback failure; wherein when the one of the one or more fallback conditions indicates the occurrence of the hard fallback failure, the first data service comprises an evolved high rate packet data (eHRPD) service, and the hard fallback failure comprises an authentication failure; and wherein when the one or more fallback conditions indicates the occurrence of the soft fallback failure, the first data service comprises the eHRPD service, and the soft fallback failure comprises a link control protocol (LCP) negotiation procedure failure.
