Abstract
Abstract A method for providing a closed user group service in mobile communication network. The mobile stations belonging to a certain CUG group must save the correspondence message identifier(ID) before start of service. For assigning or cancelling a message identifier to a mobile station, teleservice identifier(TI) message in a point-to-point short message is used. The mobile stations receive the cell broadcast message and compares the message ID of the received message with the saved message ID in their storage device. If the message ID of the received message is equal to the saved message ID, the mobile stations belonging to the certain group display the message information on their own display panel. If not, the mobile stations do not display.
