Patent ID: 7443816

Claim:
A packet transmission method in which a plurality of packets having headers and different sizes are transmitted between a mobile station and a communication device via a base station communicating with said mobile station and connected to communication device through a network, comprising the steps of, for each packet: in the mobile station, recognizing the size of each packet to be transmitted; determining a transmission time of the packet between the mobile station and the base station calculated from a transmission condition for the transmission time of the packet between the mobile station and the communication device; determining a transmission rate for each packet based on the recognized size of said packet and on the determined transmission time so that the transmission rate is higher as the recognized size of the packet is larger; notifying the base station of the determined transmission rate; in the base station, allocating a radio resource for the transmission of the packet between the base station and the mobile station based on said transmission rate received from the mobile station; transmitting the packet between the base station and the mobile station using said allocated radio resource such that variations of the transmission time of the packet between the mobile station and a communication device are reduced.
