Abstract: An apparatus and method for detecting a data transmission mode of an access point (AP) in a wireless terminal is provided. When the AP switches the data transmission mode in a state where a Wi-Fi wireless link is connected between the AP and the wireless terminal or not, the AP transmits the mode switched information to the wireless terminal with the information carried on the arbitrary field in any one of the Beacon, Probe Response, Association Response messages, and the wireless terminal compares the mode switched information included in the transmitted message with the currently set data transmission mode, switches the mode, attempts re-connection to the AP in the switched mode, and performs the Wi-Fi wireless link connection with the AP. Thereby, it is possible to provide data telecommunication services without interruption.

Abstract: A base station controller and a base station in a wireless communication system transmit data using multi-frames according to frame offsets allocated to mobile terminals to which a call has been set up. During forward data transmission, the base station controller packetizes data to be sent to each mobile terminal for each frame offset to generate the multi-frames. Then, the base station controller calls a socket function to transmit the generated multi-frames to the base stations. The base station receiving the multi-frames from the base station controller performs demultiplexing to send associated data to an associated mobile terminal. During backward data transmission, the base station packetizes data received from each mobile terminal for each frame offset to generate the multi-frames. Then, the base station calls a socket function to transmit the generated multi-frames to the base station controller. The base station controller demultiplexes the multi-frames to send the data to a mobile switching center.

Abstract: A method and apparatus are provided for alarming upon occurrence of or expected occurrence of cell secession of a mobile station in a mobile communication system. A base station transceiver subsystem (BTS) receives power-related information transmitted from a mobile station, and analyzes the power-related information to determine whether a mobile station has seceded from a corresponding cell. The BTS transmits cell secession alarm information to a cell-seceded mobile station to enable the cell-seceded mobile station to perform a cell secession alarm operation to advise a subscriber of the cell-seceded mobile station of a possible call drop.
