Abstract: In the scheduling method of the present invention, scheduling grant messages for a user equipment are transmitted beginning in any time slot of a frame for a channel so long as the scheduling grant message does not exceed the frame. The scheduling grant message indicates user equipment is approved to transmit on an uplink dedicated channel. This downlink transmission and subsequent uplink dedicated channel transmission have a timing relationship such that no more than one user equipment will begin transmitting on a respective uplink dedicated channel at a time.

Abstract: A system for allocating bandwidth resources among various mobile stations which are wirelessly connected to a base station. The length of the data queue in each mobile station is determined and information regarding that length is placed in a field in the outgoing data packet. When it is received in the base station, this field is decoded and the queue length information used to allocate bandwidth resources among the mobile station connections. This allows a very quick response to data queue lengths and accordingly better service.

Abstract: In general, techniques are described for adaptively applying network acceleration services within an intermediate network device. In particular, the intermediate network device comprises a classifier module that receives network traffic and a servicing engine. The servicing engine applies the network acceleration services to the network traffic in accordance with a service configuration and monitors the application of network acceleration services to determine whether the application of each of the network acceleration services improves the efficiency with which the network traffic is serviced. The servicing engine then dynamically adapts the service configuration to alter the application of the network acceleration services based on the determination. Thereafter, the servicing engine applies the network acceleration services to the network traffic in accordance with the dynamically adapted service configuration to more efficiently service the network traffic.
