Abstract: In a wireless data communication network, a mobile terminal is reconnected to a contents provider, when a connection established between the mobile terminal and the contents provider is interrupted or after a completion of the downloading of contents, by using return address information and contents address information including addresses of the contents provider and a web page including information relating to the downloaded contents, respectively. A WML (wireless markup language) script including the contents address information and the return address information is provided to the mobile terminal before initiating the downloading of the contents. In this way, the mobile terminal can easily be reconnected to the contents provider when the connection established between the mobile terminal and the contents provider is interrupted due to network congestion or the mobile terminal leaving the service coverage area.

Abstract: In a method for setting up theme pictures and bells of a mobile telecommunication terminal, contents data stored in a storage unit of the mobile telecommunication terminal are retrieved based on a user's setting of a theme picture and a bell. A selection window is provided to the user to select the retrieved contents data. It is to determine whether the contents data selected in the selection window are VOD contents. If the contents data are the VOD contents data, at least one among video and audio data including the VOD contents data is decoded. A setup window is provided to determine whether the theme pictures include the decoded audio data. A speaker of the mobile telecommunication terminal is controlled on or off based on a user's setting of the setup window when the theme pictures are set up.

Abstract: In a method for providing a video data streaming service, a server determines whether an occupancy is below a first threshold or is equal to or greater than a second threshold, the occupancy representing the amount of data occupying a queuing buffer of a terminal and the first threshold being less than the second threshold. If the occupancy is not below the first threshold, the server provides the data streaming service at a predetermined service bit rate which is less than the current service bit rate. If the occupancy is equal to or greater than a second threshold, the server provides the data streaming service at a predetermined service bit rate which is greater than the current service bit rate.
