Abstract: A way of optimizing communication by minimizing the momentary overall radiated energy under constraints in respect to coverage and maintenance of communication with the users, is provided herein. Channel parameters are estimated from downlink and/or uplink communications or from user equipment messages and desirable gain factors are derived from the minimization. The optimization is reiterated continuously to dynamically adapt the communication system to varying conditions.

Abstract: A method for carrying out a handover procedure, following which a mobile terminal (MS) currently in communication with a first base station (BS), will communicate via a second BS. The method includes upon initiating a handover procedure, determining that the MS will receive all future IP packets via the second base station, following this determination and prior to establishing a connection between the MS and the second BS, forwarding all IP packets being addressed to the MS to the second BS, and buffering the received IP packets thereat, and upon establishing a connection between the MS and the second BS, forwarding the IP packets that were buffered at the second BS to the MS, wherein the buffered IP packets are delivered to the MS before delivering any packets addressed thereto along a new path extending to the second BS which does not include the first BS.

Abstract: A method is provided for carrying out a power saving procedure in a wireless subscriber terminal which is operative to receive at least two different services, each of which is characterized by one or more characteristics related to traffic demands associated with that service. The method comprises the following steps: classifying each of the at least two different services based on their traffic demand related characteristics into corresponding power saving classes, where there are at least two different power saving classes associated with the at least two different services; for each of the power saving classes, determining required listening windows and required sleep windows; exchanging messages between the base station and the subscriber's device for synchronizing parameters for carrying out the power saving procedure.

Abstract: A method and devices are provided to enable continuing a communication session currently carried by a mobile subscriber station (MSS) while switching from a first base station to a second base station. During the communication session that is being held with the MSS, a first Internet Protocol (IP) datagram is selected from among a plurality of IP datagrams associated with that communication session and received at a network gateway adapted to convey IP traffic received from the MSS. Following that selection and prior to establishing a connection between the mobile subscriber terminal and the second base station, IP datagrams that will be received at that network gateway after that first IP datagram had been received and which are addressed to the MSS, are backed up.

Abstract: A method and devices are provided to allow reducing interferences occurring in adjacent wireless communication networks. When a subscriber device experiences interferences resulting from the operation of an adjacent wireless network, it transmits an adjustment signal which serves as a request for adjustment, to the base station operative at the adjacent wireless communication network. The adjacent base station that receives the adjustment signal retrieves adjustment information therefrom, and based on the retrieved information will determine whether it should effect a change in its transmission that would result in reducing the interferences experienced at the subscriber device sending the adjustment signal.
