Fast notification access channel for realtime users in egprs networks

摘要

A Fast Notification Access Channel is used in a system for multiplexing users on a shared cellular packet data traffic channel in a cellular packet data network system. The system includes a mobile station having a mobile station control system. The mobile station control system transmits packet data on the shared packet data traffic channel to a base station until it reaches an inactive period and upon having additional data to transmit transmits a notification signal to the base station, the notification signal uniquely identifying the mobile station on the shared cellular packet data traffic channel. A network control system is operatively associated with the base station. The network control system allocates uplink on the shared packet data channel to the mobile station after receiving the notification signal until the mobile station reaches the inactive period.
