ABSTRACT:
Disclosed herein is a mechanism to help improve message waiting notification. In accordance with the mechanism, when a RAN transmits an MWI to a mobile station after unsuccessful call setup paging of the mobile station, the RAN will transmit the MWI at a higher power level than the RAN used for transmitting the call setup paging. Using a higher transmission power specifically for the MWI should help the MWI reach the mobile station, particularly in a scenario where a reason for call setup paging failure was noise on the air interface. Consequently, the disclosed mechanism should help improve user experience by increasing the likelihood that mobile stations will receive and process MWIs soon after the associated voice mail messages are left.
