Title: Method for assigning channel in imt-2000 system
Inventor: OH SE JONG
IPC: H04W72/10
Filed: 1998-11-18
Abstract: PURPOSE: A method for assigning channel in IMT-2000 system is provided to offer a packet service to more users using a limit resource by processing an over-packet using a method for assigning and using a common channel when the over-packet is occurred when transmitting a packet. CONSTITUTION: It is identified as to whether an over-traffic is existed. A prior sequence of a delayed packet is identified when the over-traffic is existed. The over-packet is stored in a CLASS_1 queue of a common traffic channel when the delayed packet data is a packet data sensitive to a delay. The over-packet is stored in a CLASS_2 queue of the common traffic channel when the delayed packet data is a packet data insensitive to a delay. The packet data stored in the CLASS_2 queue is processed and transmitted after the packet data stored in the CLASS_1 queue is processed and transmitted. It is judged as to whether a state of the over-packet is continuous during a delay time(Td). A band of the common traffic channel is varied when the state of the over-packet is continuous during the delay time(Td).
