Abstract: The present invention relates to a wireless mobile communication system, and more particularly, to a method of transmitting data to mobile terminals in the wireless mobile communication system capable of transmitting multicast data. In order to solve the aforementioned problems in the prior art, a method of transmitting data to mobile terminals in a mobile terminal communicating with a network through which multicast data are transmitted. The method of the present invention comprises the steps of transmitting a requesting frame to the network for requesting the multicast data when the start of a multicast service is recognized through an upper layer of the mobile terminal; receiving a response frame from the network in response to the request frame; and receiving the multicast data from the network.

Abstract: The present invention relates to a wireless communication data transmission method considering the number of terminals requesting services. The present invention provides a wireless communication base station for use in a network where a multicast service is received from a network entity and is provided to at least one or more terminals in contention-based channel access mode of a wireless communication. The base station comprises a storage unit for storing terminal information including the number of terminals which have joined the multicast service, and a priority determining unit for setting a user priority of a data frame to be transmitted using the terminal information. According to the present invention, a priority of data to be transmitted is determined in consideration of the number of serviced terminals, and thus, the data can be reasonably transmitted.

Abstract: An apparatus and method for controlling data communication in a wireless local area network (LAN) can check a remaining power level of a host computer battery and determine a data transmission characteristic such as a data transfer speed and/or power save mode period based on the checked battery power, and then adjust the current data transfer speed or power save mode period according to the determined value. For example, a controller of a wireless LAN can transmit information corresponding to the determined transmission characteristic to an access point or another station. Therefore, a station of the wireless LAN card can reduce or prevent power of the battery from being abruptly diminished because of use of the wireless LAN.

Abstract: A user authentication method for a remote control apparatus and a remote control apparatus using this method are provided. If a user inputs information for user authentication after having inputted a command for control of a controlled device, this information is compared with the corresponding user authentication information stored. If the user authentication is successful, it is determined whether a secondary authentication is required. If a secondary authentication is required, authentication data, as well as control data corresponding to the user's command, are transmitted to the controlled device. The controlled device operates in accordance with the received control data, if the authentication with the received authentication data was successful. The method and apparatus allow individual setting of a communication device for each controlled device.
