ABSTRACT:
A radio network controller (RNC) application controls packet communications through base stations serving wireless remote stations. In the embodiments, the RNC stores each packet received for a wireless remote station in a buffer and maintains a BCN counter value representing the amount of buffered data. The RNC maintains a maximum accumulation timer (Timeracc), and it restarts an inter-packet arrival timer (Timerint) upon receipt of each packet for the station. The RNC initiates transmissions to the station in response to certain events, including expiration of either of the timers Timerintand Timeracc, and if the BCN counter value exceeds a threshold. However, the transmissions use either a dedicated channel cell-state or a forward access channel state, depending on which event triggered each transmission. The RNC also may instruct the remote station to return to the forward access channel state following communication in the dedicated channel cell-state.
