A cell broadcasting service system includes: a terminal for generating a short message service (SMS) type message and a cell broadcasting service (CBS) type message; an SMS center for transmitting a CBS type message to a CB center when receiving the CBS type message from the terminal; and a CB center for broadcasting a received message to a corresponding range area by referring to broadcast range information of the message when receiving the message from the SMS center. By assigning a CB ID to a specific subscriber group (a small circles or a local group), a general subscriber can broadcast a short message in the position of the CB entity. In addition, various get-together information and local information can be easily provided to subscribers of a group located within a broadcast range, and more efficient and substantial information can be provided at a low cost.
