Abstract: A pool of functional server nodes in a packet data network, and method of transferring a given mobile terminal from a current functional server node to a target functional server node in the pool. An interface enables each functional server node to control any, or a number of, radio network control nodes. When a transfer is desired, the pool selects the target functional server node and initiates a transfer of control responsibility for the given mobile terminal's connections from the current functional server node to the selected target functional server node. The control responsibility is then transferred to the selected target functional server node without interrupting service to the given mobile terminal.

Abstract: The invention relates to methods and arrangements for channel balancing of a wavelength division multiplexed optical signal. Channel balancing according to the invention is performed by using a resonator that provides a selection region in which a selected channel has a substantially increased poser density relative to channels out of resonance. The selected channel is attenuated a desired amount, i.e. a desired amount of power is removed therefrom, by adjusting the properties of the selection region. In a preferred embodiment, attenuation is achieved by adjusting the selection region such that destructive interference is obtained for the selected channel in a fiber carrying tile multiplexed optical signal.

Abstract: Apparatus, and an associated method, selectively transmits packets of message data between a sending and a receiving station. When a packet of message data is received at a receiving station, the receiving station acknowledges reception thereat of the packet with an acknowledgment response signal, transmitted back to the sending station. If the sending station fails to detect an acknowledgment response signal, a packet of activity-request data is sent to the receiving station. If the receiving station fails to acknowledge reception of the packet of activity-request data, a determination is made that the receiving station would be unlikely to be able to receive an additional packet of message data. A channel to be used to transmit the packet of message data can instead be reallocated for other purposes.
