A method for assisting in a cell re-selection procedure in a cellular communication system comprises obtaining (S) of information comprising radio conditions and/or user equipment population related to at least a serving cell and optionally also related to at least one neighbor cell to the serving cell. The obtained information is compared (S) with a criterion for enforced cell re-selection procedure. If the criterion for enforced cell re-selection procedure is fulfilled by the obtained information, an enforcement of, or an action for increasing the probability for causing, a cell re-selection procedure of at least one user equipment within the serving cell is initialized (S). Devices for performing such a method are also disclosed.

Cell re-selection procedure assistance and devices

An acoustic horn has an acoustic impedance matched with impedances of an ear and a driver. The acoustic horn can be used in an electroacoustic transducer including the driver, and the acoustic horn. The electroacoustic transducer is particularly well-suited for use in portable device such as a radiotelephone, pager, or other device.
