Patent ID: 8761093

Claim:
A method of controlling discontinuous reception (DRX) in user equipment (UE) based on rate shaping by a wireless communication network, comprising: rate shaping traffic transmitted by the network using a modified token bucket rate shaping algorithm comprising: maintaining a token bucket counter (TBC) representing the number of tokens in a bucket; decreasing the TBC by the size of each packet passed for transmission by the network; increasing the TBC at a constant token rate; determining whether the TBC is positive or negative, wherein the duration the TBC is negative is the negative TBC value divided by the token rate; and if the TBC is positive, passing a data packet for transmission by the network; and if the TBC is negative, withholding a data packet from transmission by the network; and if the TBC is negative, directing a UE to enter a DRX mode in which the UE does not monitor a downlink control channel for downlink traffic for the duration the TBC is negative.
