Abstract: An intermediary node is adapted for receiving a sequence of packets from a server, wherein the intermediary node comprises a time estimator adapted for performing the following steps—resolving the sequence number (k) and time of arrival to the intermediary node for at least a plurality (q) of incoming packets; establishing the frame period of the incoming packets (T); establishing a sequence of normalized packet arrival times (ek) as corresponding to the established frame period (T); calculating the relative arrival time (rtrec, k) of the plurality (q) of incoming packets in relation to the normalized packet arrival times; creating a cumulative density function (CDF) for a given sequence of packets; and establishing the threshold value for the relative arrival time (rtPL) yielding the predefined packet loss (PL) based on the cumulative density function (CDF).

Abstract: According to embodiment of the present invention, there is provided a radio base station (20) and a corresponding method for estimating the quality of the uplink control channel. The method comprises measuring (32, 42) a quality parameter of the uplink data channel, and using (38, 50) this to estimate the quality of the uplink control channel. In one embodiment, measurements of the uplink control channel are taken and their reliability determined. If the reliability is low (i.e. below a threshold, or below the respective measurements taken on the uplink data channel), then measurements on the data channel are used instead of those made on the control channel to estimate the control channel quality.
Abstract translation: 根据本发明的实施例，提供了一种用于估计上行链路控制信道的质量的无线电基站（20）和相应的方法。 该方法包括测量（32,42）上行链路数据信道的质量参数，并使用（38,50）来估计上行链路控制信道的质量。 在一个实施例中，采用上行链路控制信道的测量并确定其可靠性。 如果可靠性低（即低于阈值，或低于在上行链路数据信道上进行的相应测量），则使用数据信道上的测量来代替在控制信道上进行的测量来估计控制信道质量。
