    • A multimode antenna structure is provided for transmitting and receiving electromagnetic signals in a communications device. The communications device includes circuitry for processing signals communicated to and from the antenna structure. The antenna structure includes a plurality of antenna ports for coupling to the circuitry; a plurality of antenna elements, each operatively coupled to a different one of the antenna ports; and a plurality of connecting elements. The connecting elements each electrically connect neighboring antenna elements such that the antenna elements and the connecting elements are arranged about the periphery of the antenna structure and form a single radiating structure. Electrical currents on one antenna element flow to connected neighboring antenna elements and generally bypass the antenna ports coupled to the neighboring antenna elements such that an antenna mode excited by one antenna port is generally electrically isolated from a mode excited by another antenna port at a given desired signal frequency range, and the antenna structure generates diverse antenna patterns.

    • Embodiments of the present invention provide a method, system and computer program product for threshold activation of an audio teleconference. In an embodiment of the invention, a method for threshold activation of an audio teleconference is provided. The method includes receiving calls into a conference bridge for an audio conference and determining whether or not a threshold number of calls from corresponding callers have been received for the audio conference. The method also includes initiating the audio conference responsive to a threshold number of callers having called into the audio conference, but prohibiting initiation of the audio conference until the threshold number of callers have called into the audio conference.

    • The present invention relates to the technical field of wireless communications, is used for optimizing an energy saving mechanism, and provides a method for energy saving compensation, which method comprises: expanding, by a base station, a signal coverage area to form a new cell, when the energy saving activation requirements are met, so as to allow an energy-saving cell managed by the base station to switch users to the new cell and to activate the energy saving state; and when energy saving deactivation requirements are met, and if the energy-saving cell managed by the base station deactivates the energy saving state, then switching, by the base station, the users to the energy-saving cell and reducing the signal coverage area. The present invention optimizes currently available energy saving mechanisms and provides a solution capable of compensating the service loss of energy-saving cells.
