METHOD AND APPARATUS FOR ESTIMATING AVAILABLE BANDWIDTH FOR EACH USER EQUIPMENT IN MOBILE COMMUNICATION SYSTEM

摘要

A method for estimating an available bandwidth for each User Equipment (UE) in a mobile communication system comprises: a process of receiving estimated bandwidth information for at least one UE from an enhanced node B; a process of checking whether the estimated bandwidth information is received from a Medium Access Control (MAC) layer constituting said enhanced node B, or received through a Radio Link Control (RLC) layer or a Packet Data Control Protocol (PDCP) layer; a process of updating channel quality information using said estimated bandwidth information if it is checked that said estimated bandwidth information is received through the MAC layer; a process of updating an average value weighted with respect to the number of bytes of the bandwidth served by said enhanced node B using the estimated bandwidth information if it is checked that said estimated bandwidth information is received through the RLC or PDCP layer; and a process of calculating the bandwidth currently available by at least one UE using the updated channel quality information or the average value weighted with respect to the number of the bytes of the served bandwidth, and then transmitting the calculated bandwidth to a server.

1. A method of estimating an available bandwidth of each User Equipment (UE) in a mobile communication system, the method comprising:
receiving estimated bandwidth information for at least one UE from an enhanced node B; identifying whether the estimated bandwidth information is received from a Medium Access Control (MAC) layer constituting the enhanced node B, or through a Radio Link Control (RLC) layer or a Packet Data Control Protocol (PDCP) layer; updating channel quality information by using the estimated bandwidth information if the estimated bandwidth information is received through the MAC layer; updating a weighted average value for a number of bytes of the bandwidth served by the enhanced node B by using the estimated bandwidth information if the estimated bandwidth information is received through the RLC or PDCP layer; and calculating a currently available bandwidth of the at least one UE by using the weighted average value for the updated channel quality information or the number of the bytes of the served bandwidth, and then transmitting information on the available bandwidth to a server.
