An automatic configuration method of an IP based RAS is provided to enable the IP based RAS to set L3 information automatically, thereby solving complexity in operation of the IP based RAS. An automatic configuration method of an IP(Internet Protocol) based RAS(Radio Access Station) comprises the following steps. The IP based RAS acquires GPS(Global Positioning System) location information by using a GPS receiver. The IP based RAS transmits an RAS configuration information request message including the acquired GPS location information to a DHCP(Dynamic Host Configuration Protocol) server(S303). The DHCP server has an IP address database for storing RAS configuration information mapped with an IP address of a system management apparatus for providing information necessary for RAS loading and IP address of the RAS and the GPS location information of the RAS. The DHCP server inquiries RAS configuration information of the RAS by using the GPS location information, received from the IP based RAS, as a key value(S304). The DHCP server returns the inquired RAS configuration information to the IP based RAS(S305). The IP based RAS performs RAS loading and services by using an IP address included in the RAS configuration information received from the DHCP server(S306).

When a request occurred, the base station management apparatus (BSM) or the base station controller (BSC) was able to distinguish from which base station a communication request.

However, since an IP-based base station applied to an IP-based network such as a mobile Internet system does not have base station-specific information such as base station-specific address or path information, the base station main processor board is replaced when the main processor is replaced or a failure occurs. The operator should connect in debug mode and input L3 (Layer 3) information such as IP address. Even if the existing method is applied, if the part with unique ID such as the backboard of the base station is replaced, the strap is reassigned by the operator. Work is required.

As such, the existing base station configuration method is very cumbersome because the operator has to deal with it manually, as well as a high possibility of error due to manual input and a long work time. It is necessary to improve the L3 information setting method to solve the problem.
