    • A quality of service (QoS) securing apparatus and method using a communication protocol are provided. The method of securing a QoS of a mobile terminal that receives data while the mobile terminal moves from a first network to a second network includes generating a datagram congestion control protocol (DCCP) packet including information about link characteristics of the second network, and transmitting the DCCP packet to a transmission side. When the mobile terminal of a reception side moves to a new network, the reception side sends a transmission side information on changes in link characteristics of the reception side, and the transmission side transmits data according to the changed link characteristics, thereby securing a QoS of data communication between the reception side and the transmission side.
    • 提供了使用通信协议的服务质量(QoS)保护装置和方法。 在移动终端从第一网络移动到第二网络的过程中确保接收数据的移动终端的QoS的方法包括生成包括关于第二网络的链路特性的信息的数据报拥塞控制协议(DCCP)分组,并且发送 DCCP数据包发送到发送端。 当接收侧的移动终端移动到新网络时,接收侧发送关于接收侧的链路特性的变化的发送侧信息,并且发送侧根据改变的链路特性发送数据,从而确保 接收侧和发送侧之间的数据通信。

    • A method of adaptively updating a first recommended user group list of a first user connected to a network, in which a predetermined number of second users are selected from the first recommend user group list that is a list of users having a high similarity to the first user in consuming contents. A predetermined number of third users having a high similarity to the first user is selected from second recommend user group lists respectively of the selected second users possess. The first recommend user group list is updated to include the selected third users. As the preference of a user changes, the recommend user group may be reconfigured with updated recommend users by reflecting a corresponding preference. Also, quality contents can be provided by recommending a user of a corresponding terminal with the contents preferred by other users in the updated recommend user group list.
    • 一种自适应地更新连接到网络的第一用户的第一推荐用户组列表的方法,其中从第一推荐用户组列表中选择预定数量的第二用户,该第一推荐用户组列表是与第一用户组具有高相似性的用户列表 用户在消费内容。 分别从所选择的第二用户拥有的第二推荐用户组列表中选择与第一用户具有高相似性的预定数量的第三用户。 第一个推荐的用户组列表被更新为包括所选择的第三个用户。 随着用户的偏好改变,可以通过反映相应的偏好来重新配置推荐用户组与更新的推荐用户。 此外,可以通过向更新的推荐用户组列表中的其他用户优选的内容推荐相应终端的用户来提供质量内容。

    • A method and apparatus for predicting content preferences of an active user with reference to content preferences of other users that are similar to those of the active user, the method including: measuring similarity ratios of the active user and other users using an overlapping ratio of use of content items commonly used between the active user and the respective other users; generating a recommender list for the active user based on the measured similarity ratios; and predicting a preference rating of the first user with respect to an unused content item based on a preference rating of an other user included in the recommender list with respect to the unused content item. Accordingly, the similarity ratio between the users can be accurately measured so that reliability of a preference rating prediction system can be increased.
    • 一种参考与其他用户相似的活动用户的内容偏好来预测活动用户的内容偏好的方法和装置,所述方法包括:使用重叠的使用比率来测量活动用户和其他用户的相似比 在活动用户和相应的其他用户之间通常使用的内容项目; 基于测量的相似性比例生成活动用户的推荐者列表; 以及基于关于所述未使用的内容项目的所述推荐者列表中包括的其他用户的偏好评级来预测所述第一用户相对于未使用内容项的偏好评级。 因此,可以精确地测量用户之间的相似度,从而可以提高偏好评级预测系统的可靠性。
