The proposed SELFNET project will design and implement an autonomic network management framework to achieve self-organizing capabilities in managing network infrastructures by automatically detecting and mitigating a range of common network problems that are currently still being manually addressed by network operators, thereby significantly reducing operational costs and improving user experience. SELFNET explores a smart integration of state-of-the-art technologies in Software-Defined Networks (SDN), Network Function Virtualization (NFV), Self-Organizing Networks (SON), Cloud computing, Artificial intelligence, Quality of Experience (QoE) and Next-generation networking to provide a novel intelligent network management framework that is capable of assisting network operators in key management tasks: automated network monitoring by the automatic deployment of NFV applications to facilitate system-wide awareness of Health of Network metrics to have more direct and precise knowledge about the real status of the network; autonomic network maintenance by defining high-level tactical measures and enabling autonomic corrective and preventive actions against existing or potential network problems. SELFNET is driven by use cases designed to address major network management problems including Self-protection capabilities against distributed cyber-attacks, Self-healing capabilities against network failures, and Self-optimization to dynamically improve the performance of the network and the QoE of the users. SELFNET is designed within this economic and business context to substantially reduce operational costs of network operators by automating a significant number of current labour-intensive network management tasks. Therefore, SELFNET directly addresses the Strand Network Management challenge highlighted by the EC.


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.

A communication system architecture is provided, having an aggregator, arranged to centralize the access units and coordinate the radio signals of access units of different types digitally, and remote radio units configured to be modularly connectable to different types of radio elements that correspond to the access units and arranged to communicate with the aggregator digitally. Radio signals are scheduled and delivered with respect to the types of the access units and of the radio elements, and the aggregator is further arranged to handle distribution and combining of the radio signals digitally. The aggregator further comprises a controller arranged to continuously optimize communication with respect to the access units and user mobile communication devices by applying a decision process to cost functions that depends on communication parameters to derive specified dynamically changing parameters, and to manage the aggregator dynamically with respect thereto.

Provided herein is a dynamically coordination of a distribution of radio signals via distributed remote radio units, with respect to changing numbers and locations of user equipment. A distributing and combining unit combines uplink radio signals from the remote radio units and distributes downlink radio signals from the access unit according to dynamically changing specified criteria. A measurement unit measures performance indicators of the communication between the remote radio units and the mobile communication devices into a matrix of performance indicator values, calculates cost functions therefrom and generates output execution parameters by applying a decision process based on the calculated cost function. Communication criteria are dynamically updated according to the generated output execution parameters and the process is continuously iterative. The invention allows incorporating smart capabilities into legacy networks without any major physical changes of the network.


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.


A method and devices are provided to enable operation while experiencing reduced interference of at least two base stations in a wireless network wherein at least one of base stations is deployed in a femto deployment configuration and at least one of the others is deployed in a different deployment category. The method comprises preventing the usage of at least one radio resource selected from among sub-carriers comprised within a radio channel and/or time-domain resource, from one of the at least two base stations.


A method device and system are provided for managing a wireless local area network comprising a plurality of station units (STAs), where each of the plurality of station units is adapted to wirelessly communicate with one or more access points. The method device and system comprises affecting power control over air time request packets transmitted by respective station units from among the plurality of STAs towards one of the one or more access points, so that all air time request packets are received at said access point at substantially the same Signal to Noise Ratio (SNR), and wherein said power control does not affect packets carrying payload data that proceeds the air time request packets transmitted by the respective station units.
