Abstract
A method and system for improving interoperability of a radio network controller and a base station in cellular systems with downlink congestion control is disclosed. A message is sent from a base station to a radio network controller after the base station has discarded at least one transport block. The message sent to the radio network controller may be forwarded by the radio network controller to additional radio network controllers serving users affected by the discard of the at least one transport block.
Claims22
A method for communicating between a radio network controller and a base station comprising:
- monitoring transport blocks sent from a radio network controller to a base station;
- determining whether the base station has discarded at least one transport block sent from the radio network controller to the base station;
- and
- sending a block discard notification from the base station to the radio network controller when the determination is positive.
A system for improving interoperability of a radio network controller and a base station in cellular systems with downlink congestion control, the system comprising:
- a base station;
- and
- a radio network controller wherein the base station is adapted to send a block discard notification to the radio network controller, the block discard notification notifying the radio network controller that the base station has discarded at least one transport block.
A system as in 15 wherein the controlling radio network controller forwards the block discard notification to serving radio network controllers, the serving radio network controllers serving users affected by the at least one discarded transport block.
A base station for improving interoperability between a base station and a radio network controller cellular systems with downlink congestion control, the base station being adapted to send a block discard notification to the radio network controller.
A base station as in 20 wherein the block discard notification further comprises, for each transport channel that has sustained a discard of at least one transport block, the number of transport blocks which have been discarded during the specified interval of time.
A base station as in 19 wherein the block discard notification further comprises, for each transport channel that has sustained a discard of at least one transport block, the number of transport blocks processed.
