A mobile communication system is a system that services voice and data over a wireless communication network. The mobile communication is realized by transmission and reception of radio signals by a mobile terminal to and from a radio base station and transmission and reception of wire signals by the radio base station to and from a network connecting to a communication target. Mobile telecommunication systems include wireless links between mobile stations, which may be mobile telephones, pagers, computers, etc., and a base station of the mobile telecommunication system. Mobile communication service systems may be classified into synchronous mobile communication systems and asynchronous mobile communication systems. Asynchronous mobile communication systems are classified into WCDMA (wideband code division multiple access) systems and UMTS (universal mobile telecommunications system) which has been adopted as European Standard (ES). Synchronous mobile communication systems accurately establish synchronization with all base stations by employing GPS satellites. Global positioning system (GPS) is a system for detecting a current location by receiving a radio wave transmitted from a satellite. A wireless communication terminal with a GPS satellite signal receiver receives information on its current location from a GPS satellite, and transmits the location information to a GPS server of a wireless communication service provider. Synchronous mobile communication systems, such as second-generation CDMA systems, are serviced in Korea and the USA, and CDMA2000, which has been adopted as American National Standard. A mobile communication system is generally constructed of a base station and a plurality of mobile stations communicating with each other via the base station. A mobile communication system includes a plurality of base stations which are distributed over the service area. Signals transmitted by the mobile units are received by a base station and often relayed to a mobile switching center (MSC). The MSC in turn routes the signal to a public switched telephone network (PSTN) or to another mobile station. A mobile communication terminal selects one of the base stations, which has the best condition for communication and acquires the selected base station to enable radio communication.
