Method of managing terminal and controlling interference in small base station

摘要

A method of managing a terminal and controlling an interference in a small base station is provided. The small base station, including: an access preamble control unit to assign a unique preamble for each terminal registered in the small base station; a transmitting/receiving unit to receive a random access request message from each of the terminals through the unique preamble, to transmit a reply message to each of the terminals, and to receive information about each of the terminals and a Radio Resource Control (RRC) connection request Message from each of the terminals in response to the reply message; and a terminal verification unit to verify whether each of the terminals is a registered terminal using the information about each of the terminals.

1. A small base station, comprising: an uplink resource control unit to allocate to all terminals a preamble index for a random access for a physical layer or a scheduling identifier that are in the small base station for the random access process or a Radio Resource Control (RRC) connection when each of the terminals are registered in the small base station, before RRC connection of each of the terminals; a transmitting/receiving unit to receive a random access request message from each of the terminals using the preamble index or the scheduling identifier, to transmit a reply message to each of the terminals for the random access, and to receive terminal information about each of the terminals and a RRC connection request message from each of the terminals in response to the reply message; and a verification unit to verify whether the small base station provides service to each of the terminals using the terminal information about each of the terminals, wherein the transmitting/receiving unit makes the RRC connection with each of the terminals in response to the RRC connection request message, when the small base station provides service to each of the terminals.
