    • A method uses a relay station to assist processing of requests from user ends. The relay station acquires and monitors channel resource information received from a base station. Upon receiving a request from the UEs via the channel resource, the relay station sends the request received to the base station if it detects no response from the base station to the request. An apparatus uses a relay station to assist processing of requests from UEs. A channel resource acquisition unit acquires channel resource information from the base station. A user monitoring unit monitors the channel resource acquired by the channel resource acquisition unit and for receiving requests sent from the UEs. A base station monitoring unit monitors response from the base station to the requests upon receiving the requests sent from the UEs. A transmitting unit sends the request to the base station when no response from the base station to the request is detected.
    • 一种方法使用中继站来帮助处理来自用户端的请求。 中继站获取并监视从基站接收到的信道资源信息。 在经由信道资源从UE接收到请求时,如果中继站检测到没有从基站到请求的响应,则将所接收的请求发送到基站。 一种装置使用中继站来帮助处理来自UE的请求。 信道资源获取单元从基站获取信道资源信息。 用户监视单元监视由信道资源获取单元获取的信道资源,并用于接收从UE发送的请求。 基站监视单元在接收到从UE发送的请求时监视从基站到请求的响应。 当没有检测到来自基站的响应时,发送单元将该请求发送到基站。

    • Systems and methods of perceptual quality monitoring of video information, communications, and entertainment that can estimate the perceptual quality of video with high accuracy, and can be used to produce quality scores that better correlate with subjective quality scores of an end user. The systems and methods of perceptual quality monitoring of video can generate, from an encoded input video bitstream, estimates of one or more quality parameters relating to the video, such as the coding bit rate parameter, the video frame rate parameter, and the packet loss rate parameter, and provide these video quality parameter estimates to a predetermined video quality estimation model. Because the estimates of the video quality parameters are generated from the encoded input video bitstream as it is being received, the systems and methods are suitable for use as QoE monitoring tools.
    • 视频信息,通信和娱乐的感知质量监控的系统和方法可以高精度地估计视频的感知质量,并且可以用于产生与最终用户的主观质量得分更好相关的质量分数。 视频的感知质量监视的系统和方法可以从编码的输入视频比特流中产生与视频相关的一个或多个质量参数的估计,例如编码比特率参数,视频帧速率参数和分组丢失 速率参数,并将这些视频质量参数估计提供给预定的视频质量估计模型。 因为视频质量参数的估计在编码的输入视频比特流被接收时产生,所以系统和方法适合用作QoE监视工具。
