Abstract: A system that provides a content delivery service to a user in a mobile communication system is provided. The system receives, from an enhanced Node B (eNB), cell-specific capacity information that is determined based on cell-specific load state information of the eNB, determines a transfer rate for traffic to be transmitted to a User Equipment (UE) in each cell, based on the received cell-specific capacity information, and transmits the traffic to be transmitted to the UE in each cell to the eNB at the determined transfer rate.

Abstract: A method for transmitting data in a core cache server of a communication system, according to one embodiment of the present invention, comprises the steps of: receiving, from a source base station, a core cache search signal; selecting a relay core cache unit according to the received core cache search signal; and transmitting content data to a target base station through the selected relay core cache unit. A cache server for transmitting and receiving data in a communication system, according to another embodiment of the present invention, comprises: one or more core cache units for storing content data; a receiving unit for receiving, from a source base station, a core cache search signal; a control unit for selecting a relay core cache unit among the one or more core cache units according to the received core cache search signal; and a transmission unit for transmitting the content data to a target base station through the selected relay core cache unit. When the present invention is used, the source base station can continuously provide content to a terminal by transmitting session information and the content to a target base station during a handover of the terminal by using a logical interface between base stations in an LTE system, and in this case, a core cache function is additionally provided such that it is possible to smoothly provide the content to a base station even when moving to a server that does not have a cache function. Thus, backhaul costs caused by a handover are reduced and a user can be provided with improved quality of experience.
