- In a base station of an IEEE 802.16 Wireless MAN-based portable Internet system, a forward packet scheduling method and apparatus is provided. The portable Internet system portable Internet service includes a user terminal AT for providing a portable Internet service, a base station AP for supporting an inter-user terminal wireless access and network connection, and a packet access router PAR for performing a mobility control and packet routing function of each user terminal AT. The forward packet scheduler includes a packet-based subsidiary scheduling part for considering a real-time service and a user-based scheduling part for ensuring fairness and increasing system efficiency (throughput). After finishing the 2-step scheduling, the generated frame data are transmitted though a physical layer to a wireless user terminal. Therefore, with such a structure, the forward packet scheduling method may guarantee a maximum of system efficiency and fairness according to each user's QoS requirements, and may also guarantee a delay performance for a real-time service.
