The present invention relates to a mobile communication system, and more particularly, to a femto base station installation method, a femto base station and a femto base station installation control apparatus applicable to self-configuration of a femto base station.

Recently, with the development of information communication and multimedia technology, the demand for new mobile communication service is increasing, and femtocell, which is a wired / wireless convergence technology, is in the spotlight due to the development of wired / wireless communication technology.

Femtocell is an ultra-compact mobile communication base station used indoors such as homes and offices, and it is attracting attention from telecommunication companies around the world in that it can solve the shadow area and use it as an indoor communication infrastructure for wired / wireless converged service. (3 rd Generation Partnership Project Long Term Evolution) and is included in the IEEE (Institute of Electrical and Electronics Engineers ) 802.16 standard is underway.

Femtocells integrate a femto base station, a compact, low-power access point, into a traditional Digital Subscriber Line (DSL), cable broadband connection, or fiber-optic gateway, allowing users to deploy the femto base station in their home or small business. It allows users to freely use wired / wireless communication with a mobile phone by connecting to a protocol-based broadband network, and can transmit mobile data from a base station to a femtocell directly without going through an indoor relay, thereby reducing the cost of network construction and reducing the frequency load. Reduce and improve call quality.

On the other hand, due to the requirement that the femtocell should not be installed at the optimal location designated by the mobile operator but should be directly installed and operated by the general user, the mobile operator cannot design the cell arrangement in advance. The femto base station itself should detect the environment and perform self-configuration and self-optimization.

In order to meet the above requirements, the 3GPP LTE standard provides a self-organizing network (SON: Self) including self-configuration, self-optimization, and self-healing of femtocells. -Organizing Network) is being standardized.

Self-configuring function collects and analyzes the parameters necessary for the initial operation of the base station when new or additional installation of the base station itself. To automate the procedure.

Self-optimization features utilize base station signal and traffic type information during base station operation and maintenance to control base station signal strength to minimize inter-base station interference, optimize random access channel (RACH), and radio link failure during handover Optimization of handover parameters to minimize), load balancing between adjacent base stations, and power savings to minimize unnecessary base station operating time. Here, the base station performs the above-described self-configuration and self-optimization function in cooperation with the configuration server (configuration server).

Self-healing is a function to identify the failure of the components that occur during the operation of the base station and to recover the elements that can be automatically repaired to solve the error or minimize the impact of the error. For example, the self-healing function monitors alarms generated when a femto base station failure occurs, collects additional information through measurement or inspection when an alarm occurs, and then performs a corresponding recovery operation when automatic recovery is possible. Includes skills.

The SON server 300 may include an installation region determining unit 310 and a self-organizing control unit 330.

The installation area determiner 310 determines an area in which the femto base station 200 is to be installed based on the region identification information transmitted from the femto base station 200, and provides the determination result to the self-configuring controller 330.

Here, the installation area determination unit 310 may extract the network identification information (PLMN ID) from the at least one area identification information transmitted from the femto base station 200 and provide it to the self-organizing control unit 330, the femto base station ( The location information transmitted from the 200 may be provided to the self-configuration controller 330. Alternatively, the installation area determination unit 310 determines the current location of the femto base station 200 from the IP address included in the message transmitted from the femto base station 200, and self-configured the location information of the determined femto base station 200 It may be provided to the control unit 330.

The self-organizing control unit 330 compares the network identification information of the femto base station 200 provided from the installation area determining unit 310 with the network identification information of the service provider or the communication network operator, and the femto base station 200 is located in a predetermined installation permission area. It determines whether the location, and based on the determination result transmits an installation control message for controlling whether or not the femto base station 200 is installed to the femto base station 200.

Alternatively, the self-configuration controller 330 determines whether the femto base station 200 is located in an area where the femto base station 200 can be installed based on the location information or the IP address of the femto base station 200 provided from the installation area determination unit 310, and then the determination result. Based on the control of whether the femto base station 200 may be installed.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined in the appended claims. It will be possible.
