Patent ID: 7626932

Claim:
An apparatus, comprising: a processor configured to measure a traffic situation in an internet protocol-based communication network based on traffic situation data, wherein part of the traffic situation data is topology and routine data from a core internet protocol network and part of the traffic situation data is traffic load information from a radio network, and control a traffic flow based upon the measured traffic situation from the core internet protocol network and the radio network, wherein the processor is configured to transmit data via frame protocol frames on an interface between a radio network controller and a base station, wherein the frames comprise information to support flow control between the radio network controller and the base station or a node B, and the frames comprise at least one of an identifying field that identifies a number of a medium access control high speed data unit in the frame, an indicating field that indicates a buffer status of one or more radio network controller buffers and informs the base station or node B how much data belonging to the same traffic flow is still left in the radio network controller, a containing field that contains a user equipment identity type and a common transport channel priority indicator, and a buffer data indicating field that indicates a number of radio network controller buffers from which data has been applied into the frame.
