Provided are an in-memory management system and method using user traffic. According to embodiments thereof, traffic bandwidth is monitored for an ERP user who has left an LAN coverage area, by using an OpenFlow-based SDN WAN, and loading or unloading of a table partition set, an SQL Plan cache, and an SQL view cache in an in-memory is managed depending on a result of monitoring, so that the in-memory can be efficiently managed. The user traffic for the ERP user and the user can be monitored through the local network, and loading or unloading of table partitions of the in-memory can be managed on the basis of the monitored user traffic so that the in-memory can be managed regardless of Internet access. Data transmission rate and security can be enhanced because distributed communication is performed over an LAN and a WAN for each user and each ERP user.

In-memory management system and method using user traffic

The present invention discloses a power control apparatus and method in a wireless communication system. According to the present invention, among FUE units neighboring to an MUE unit of a victim cell, an FUE unit of an aggressor cell may be derived on the basis of information on RSRP of the FUE unit registered in a closed subscriber group, and a threshold interference value of the FUE unit. Also, power of the derived FUE unit of the aggressor cell may be gradually decreased until an interference of the MUE unit of the victim cell becomes greater than a predefined threshold interference value, and an SINR of the FUE unit of the aggressor cell becomes equal to or greater than a target SINR. Accordingly, CCI can be reduced in a heterogeneous network environment, data transmission speed can be improved, and latency time can be reduced by reducing feedback time.
