Abstract: A device and a method are provided. The device may include: a first encoder arranged to apply a first type encoding process on an input frame element to provide a first type encoded frame element; the input frame elements belong to an input frame; a second encoder arranged to apply a second type encoding process on the input frame element to provide a second type encoded frame element; wherein the first type encoding process differs from the second type encoding process by a degree of expected loss of data; a control circuit arranged to select a selected frame element out of the first and second type encoded frame elements; a memory unit arranged to store information about the selected frame element; and an output interface arranged to output the selected frame element.

Abstract: A method and corresponding device for maximum number of sessions restriction, featuring system performance monitoring, and ensuring that there is no degradation as a result of either receiving a new user or of other network parameter changing.
