ABSTRACT:
A method and system for improved buffering during a flow control event, the system comprising: a mobile station having a mobile timer; a radio network communicating wirelessly with the mobile station and including: a base station; and a packet control function (PCF) capable of interrupting the flow of data to the wireless device during the flow control event; a packet data serving node (PDSN) communicating with the PCF and having a buffer to store data received for the mobile station during the flow control event, the buffer having a buffer timer; and a push function communicating with the PDSN and having a retry timer to indicate when to resend an unacknowledged packet; wherein the system coordinates the buffer timer with either the mobile timer or the retry timer to eliminate redundant messages.
