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.

Method and device for providing content in mobile communication system

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.

Method and apparatus for controlling traffic transfer rate based on cell capacity in mobile communication system

A terminal, a method for operation of the terminal, and a method of interworking in a wireless communication system including an advanced network and a legacy network are provided. The method for operating the terminal includes monitoring a paging channel of the legacy network for a data paging message and a Circuit Switched (CS) paging message, when the terminal is in an idle state, receiving one of the CS paging message and data paging message, establishing a connection with the legacy network corresponding to the received one of the CS paging message and data paging message, wherein a CS voice connection is established with the legacy network if the CS paging message is received and a Packet Switched (PS) data connection is established with the legacy network if the data paging message is received, and performing a handover to the advanced network from the legacy network, if the PS data connection is established with the legacy network.

Terminal, method for operating the terminal, and method for interworking in wireless communication system including 3GPP LTE network and 3GPP legacy network
