Abstract:
1. A method for scheduling a packet transmitted to a user terminal from a base station, the base station supporting a wireless access and a network connection of the user terminal, the method comprising: a) determining multimedia service types provided by the base station, selecting a given scheduling algorithm corresponding to the respective multimedia service types based on quality of service for the respective multimedia service types, determining a transmission order of packets by applying the selected scheduling algorithm to the packets received through the network, forming a transmit wait queue, determining an amount of data allocation for each service available in a current frame in consideration of data service rates for the respective multimedia service types and a total number of packets queued for each service and selecting packets corresponding to the determined amount of data allocation for each service according to a scheduling algorithm applied for each service and storing packet information in the transmit wait queue; and b) allocating radio resources to the packets queued in the transmit wait queue, determining the size of transmittable data, generating a protocol data unit (PDU) based on the size of the transmittable data, and generating frame data formed of a plurality of PDU bursts, wherein the multimedia service types include a real-time service, a non-real-time service and a best-effort service.
