Abstract:
1. A method for message waiting notification comprising: paging a mobile station at a first transmission power level over an air interface from a radio access network, to alert the mobile station of an incoming call for the mobile station; detecting failure of the paging; maintaining in data storage at the radio access network a set of data that identifies the mobile station and that specifies a failure-time indicative of when the failure of the paging occurred; receiving a message waiting indicator into the radio access network from a messaging system, for transmission of the message waiting indicator via the air interface from the radio access network to the mobile station, the message waiting indicator having a message waiting indicator time; thereafter transmitting from the radio access network to the mobile station a message waiting indicator, and, responsive to having detected the failure of the paging, performing the transmitting of the message waiting indicator at a second transmission power level greater than the first transmission power level; and conditioning the performing of the transmitting at the second transmission power level on a determination that a message waiting indicator time is within a threshold time of the failure-time.
