    • A user interface method and a mobile terminal is disclosed. If a finger touches and moves in a specific direction on a keypad having a touch sensor, a touch is detected by the touch sensor and a type of touch direction is identified by a control unit according to the angle of a touch direction. A screen of a display unit is partitioned into a plurality of blocks, and a screen highlight is located at a specific block. The control unit for moving the screen highlight on the display unit according to the type of the touch direction. A path of the screen highlight is set in one of a forward direction with continuous movement, a forward direction with discontinuous movement, a backward direction with continuous movement, and a backward direction with discontinuous movement. A user interface according to the present invention can include a pointer in the display unit, the pointer being controlled by linking a pointer position with a touch position.
    • 公开了用户界面方法和移动终端。 如果手指在具有触摸传感器的键盘上以特定方向触摸并移动,则触摸传感器检测到触摸,并且根据触摸方向的角度由控制单元识别触摸方向的类型。 显示单元的屏幕被划分为多个块,并且屏幕亮点位于特定块。 控制单元,用于根据触摸方向的类型在显示单元上移动屏幕高亮。 屏幕亮点的路径被设置为连续移动的向前方向之一,具有不连续移动的向前方向,具有连续移动的向后方向以及具有不连续移动的向后方向。 根据本发明的用户界面可以包括在显示单元中的指针,通过将指针位置与触摸位置相链接来控制指针。

    • Provided are an apparatus and method for ensuring fairness of user datagram protocol (UDP) data transmission in an Ethernet environment. Transmission control protocol (TCP) transmission rate calculator calculates a current TCP transmission rate based on amount of a TCP data stream transmitted in real time from a transmission apparatus and received by a reception apparatus. TCP transmission rate calculator calculates the optimum transmission rate on the basis of the received amount of a TCP data stream transmitted to the reception apparatus before UDP data transmission of the transmission apparatus is started. When UDP data is transmitted from a transmission apparatus to a reception apparatus, a TCP data stream for determining fairness is transmitted together, so that the apparatus and method can be simplified by adding only the TCP stream without an additional module for estimating a queuing delay time on the basis of a round-trip time (RTT) and so on.
    • 提供了一种用于确保在以太网环境中用户数据报协议(UDP)数据传输的公平性的装置和方法。 传输控制协议(TCP)传输速率计算器基于从发送设备实时发送并由接收设备接收的TCP数据流的量来计算当前TCP传输速率。 在传输装置的UDP数据传输开始之前,TCP传输速率计算器基于发送到接收装置的TCP数据流的接收量来计算最佳传输速率。 当从发送装置向接收装置发送UDP数据时,一起发送用于确定公平性的TCP数据流,从而可以仅通过添加TCP流来简化装置和方法,而不需要用于估计排队延迟时间的附加模块 基于往返时间(RTT)等。
