The present invention discloses an enhanced base station, which includes a Um interface functional module (1), a base station functional module (2), a controller functional module (3), and an A interface functional module (4), wherein the Um interface functional module (1), the base station functional module (2) and the A interface functional module (4) carry out the function of a BTS, and the controller functional module (3) and the A interface functional module (4) carry out the function of a BSC. The present invention also provides a method and a GSM system for realizing a flat mobile communication, wherein the enhanced base station carries out the functions of a BTS and a BSC in a conventional GSM system. Application of the present invention can decrease the number of devices for constituting the GSM system and the number of forwarding devices between a calling MS and a called MS, therefore reduce the time for service data transmission and improve the reliability of the transmission. |
