    • A user equipment (UE) and method of improving video call quality during handover are generally described. After determining that handover has started (306), the UE may suspend (308) frame transmission and store the frames. After determining that handover has completed (310), the UE may discard (312) frames whose age exceeds a predetermined percent of a latency deviation computed from a real-time transport control protocol report. The UE may determine whether transmission of the remaining frames would exceed a delay proportional to a video frame interval multiplied by an uplink bandwidth for a cell to which the UE is connected or a maximum bitrate of a guaranteed bitrate bearer multiplied by a typical period for a non-access stratum bandwidth and discard frames in order of decreasing age until neither the bitrate nor the delay is exceeded by the transmission.
    • 通常描述用户设备(UE)和在切换期间提高视频通话质量的方法。 在确定切换已经开始(306)之后,UE可以暂停(308)帧传输并存储帧。 在确定切换已经完成(310)之后,UE可以丢弃(312)其年龄超过从实时传输控制协议报告计算的等待时间偏差的预定百分比的帧。 UE可以确定剩余帧的传输是否将超过与视频帧间隔相乘的延迟与UE连接的小区的上行链路带宽相乘的延迟,或者保证比特率承载的最大比特率乘以一个典型周期, 非接入层带宽和丢弃帧按照时间递减的顺序排列,直到传输不超过比特率和延迟。

    • A data communication network (1;10;100), includes a transmitting node (200); a receiving node (300); and a connection (400) between the transmitting node (200) and the receiving node (300) The receiving node (300) is arranged to process data received from the transmitting mode via the connection (400). The network further includes a first measuring unit (350) which is connected with a measuring input (351 ) to the receiving node (300). The first measuring unit can determine a first parameter value forming a measure for the data processing capacity of the receiving node (300). A calculator (370) has an input (371 ) connected to an output (352) of the measuring unit (350) and can derive from the first parameter value a second parameter value forming a measure for the transmission rate of data from the transmitting node (200) to the receiving node (300). A transmission control unit (230) has a transmission control input (231 ) connected to a calculator output (372) and a transmission control output (232) connected to the transmitting node (200). The transmission control unit (230) can control a transmission of data via the connection (400) based on the determined measure for the transmission rate.

    • A method of communication of conversational data signals, especially voice signals, between transceiver terminals (A, B) over a radio link, especially a bluetooth link, capable of full-duplex transmission of conversational data packets in alternate directions within a pair (T1 to T16) of time slots. Local conversational activity is detected at each of the terminal (A, B). Any conversational activity signal (VAD) sent from the other terminal (B, A) is detected, the conversational activity signals (VAD) sent from the other terminal being indicative of the detected local conversational activity at the other terminal (B, A). The reception and transmission is controlled in response to the detected conversational activity signals from the other terminal (B. A). Controlling the reception and transmission comprises at least partially disabling reception means at the terminal (A, B) if remote conversational activity is not detected from received conversational activity signals, at least partially disabling the transmission means of the terminal (A, B) in the absence of detected local conversational activity, and generating audible comfort noise at the terminal (A, B) from a locally generated comfort noise signal if remote conversational activity is not detected from the received conversational activity signals.

    • A communication device comprising an internal power source, receiver means for receiving signals transmitted from the base station, and processing means selectively responsive to an interrogation signl received from a base station to generte a data signal fro transmission to the base station. The receiver means comprises a first receiver element and a second receiver element, the first receiver element having lower power consumption than the second receiver element does when energised. At least during a standby state of the device, the internal power source energises the first receiver element so as to detect the presence of a entergised from the internal power source. The first receiver element is responsive to detection of a received signal to trigger an active state of oepration of the communication device in which the internal power source energises the second receiver element so that the second receiver element is selectively responsive to a characteristice of the signal received to actuate the processing means. The invention is applicable to access control systems, especially to cehicle access control systems, and also to tyre pressure monitoring systems.
