Abstract
A mobile terminal receives a class identifier and receives a broadcast message with a backoff period definition for multiple classes of mobile terminals. The mobile terminal applies the class identifier to the backoff period definition to determine a backoff interval for the mobile terminal. The mobile terminal sends, to a base station, a radio resource control (RRC) connection request using the calculated backoff interval. Different backoff intervals are assigned to different classes of mobile terminals to control network access congestion at the base station.
