Abstract
A modified token bucket algorithm in a rate shaper in a wireless communication network allows for the 'borrowing' of tokens, creating the possibility of a token debt, or a token bucket with a negative Token Bucket Counter (TBC) value. In this modified token bucket algorithm, an incoming packet is passed along so long as the TBC is positive, even if the packet must 'borrow' some tokens, driving the TBC negative. Subsequent incoming packets are stalled until the TBC reaches a positive value. The token bucket refills at a known rate; accordingly, the duration of traffic stalling, when the TBC is negative, is known. During this time, the UE is forced into DRX mode, saving battery power by not monitoring DPCCH for traffic that has been halted. The DRX, or sleep, mode may be invoked in several ways.
