Claim:
1. A method of estimating an available data rate of a user equipment (UE) by an enhanced node B in a mobile communication system, the method comprising: obtaining bandwidth information estimated from at least one layer of the enhanced node B, and identifying the obtained bandwidth information; when the identified bandwidth information comprises channel quality information, updating a parameter related to a channel status based on variation of the channel quality information, wherein the variation of the channel quality information is obtained from a difference value between the channel quality information and a previous channel quality information; when the identified bandwidth information comprises served data rate information, updating an amount of data served by the served data rate information; and determining an available data rate of the UE using at least one of the updated parameter and the updated amount of data, and transmitting information on the determined available data rate to a server.
