Abstract: There are provided measures for satellite coverage change handling. Such measures exemplarily include, at a network entity managing a first cell of a mobile network and a second cell of said mobile network, the first cell covering a geographical area, and the second cell covering said geographical area, maintaining assignment of a first satellite beam corresponding to a first passing satellite to said first cell, a first satellite beam coverage of said first satellite beam overlapping with said geographical area, determining entrance of a second satellite beam coverage of a second satellite beam corresponding to a second passing satellite into said geographical area, assigning said second satellite beam to said second cell, and deciding to trigger handover of a terminal located within said second satellite beam coverage within said geographical area and served by said first cell to said second cell.

Abstract: A method and apparatus are provided for determining the quality of a speech transmission, including temporal clipping, delay and jitter, using a carefully constructed test signal (300) and digital signal processing techniques. The test signal that is to be transmitted through a speech transmission system (100) is created (700). Then the test signal is transmitted through the speech transmission system such that the speech transmission system creates an output signal that corresponds to the input signal, as modified by the speech transmission system (702). The test signal includes multiple segments (500) of speech signals interleaved with periods of silence. The periods of silence vary in duration according to a predefined pattern. Each segment of speech signals includes multiple predefined speech samples or symbols (400, 402, 404, 406, 408, 410, 412, 414) interleaved with a plurality of silence gaps. The speech samples have a common period of duration, but the silence gaps do not.

Abstract: A method and apparatus for providing call admission control in a packet network such as an internet protocol (IP) network are provided. More particularly, a terminating endpoint of a logical connection on a packet network, e.g. an IP network, is provided with the ability to make a decision on whether to accept or reject an incoming call based on quality of service (QoS) indicator based on QoS metrics. These metrics indicate quality of service levels for specific logical connections and are accumulated over specified time periods.

Abstract: A maintenance component of an apparatus in one example employs one or more packets that are communicated over an active packet connection to evaluate the active packet connection.
