A communication network comprises a plurality of subnetworks including a first subnetwork and a second subnetwork. Each subnetwork is assigned at least one predefined Quality of Service class according to at least one Service Level Agreement. The Quality of Service classes of the subnetworks are managed by a central Quality of Service manager. The communication network further comprises a radio access network with a plurality of radio access entities. A method for controlling radio access resources in the communication network includes: transmitting, by the central Quality of Service manager, information relating to a Quality of Service class of the first subnetwork to a first radio access entity for radio access to the first subnetwork.

A method for optimizing network spectrum utilization of a wireless communications network utilizing a radiofrequency spectrum includes determining, by a processor, spectrum resources at a location by determining the properties of the communication nodes and the utilization of bandwidth by all priority classes of user terminals in a defined area. Future geo-located contextual network needs for users terminals of a plurality of priority classes in the defined area is predicted by the processor based on historical profiles. The use of the radiofrequency spectrum is optimized by the processor based on the priority classes of the user terminals and the future geo-located contextual network needs of the user terminals in the defined area.

Contextual and predictive prioritization of spectrum access

A method for network controlled optimization of hybrid access traffic management for a residential user connected via a hybrid access home gateway, which provides at least two different network links with different technology to a core network, wherein the core network has a connection to the internet, wherein in the core network a Hybrid Access Server is located, includes: extracting by the Hybrid Access Server one or more of the following information: Network link availability, Network link utilization, Quality of Service information with respect to the services requested from the home gateway; and selecting networks links, network traffic routing, and/or service routing by the Hybrid Access Server in communication with the hybrid access home gateway and/or other components in the network.

A method of controlling electronic data transmission between a mobile communication device located in a movable or moving vehicle and a mobile communication network includes obtaining at least one of location data and movement data relating to the current position of the vehicle. At least one of location data and movement data relating to a predicted position of the vehicle is calculated based on the at least one of location data and movement data relating to the current position of the vehicle. A current capacity situation of the mobile communication network is determined and a future capacity situation of the mobile communication network is predicted. Network and service parameters associated with a mobile communication system are dynamically adapted based on the current position and the predicted position of the vehicle and on the current capacity situation and the predicted future capacity situation of the mobile communication network.

Method and system for proactive and dynamic cross-layer optimization of data transmission to vehicles

A method for wireless data transmission between a transmitter and a receiver includes modulating signals onto an electromagnetic carrier wave in a frequency range between 0.1 and 10 terahertz, and transmitting the carrier wave by the transmitter and focusing the transmitted carrier wave in the direction of the receiver. The transmitter is aimed towards the receiver by an adjusting system using a wireless communication link between the transmitter and the receiver so as to provide automatic aiming.

A method and a system is provided for optimizing the throughput of a TCP flow from a TCP source to a TCP destination in a wireless network with the path of the flow encompassing a wireless link between a wireless transmitter and a wireless receiver. The throughput is optimized by using link-layer mechanisms at the wireless transmitter which are adaptive to the instantaneous TCP dynamics of the TCP flow. In particular, a cross-layer approach is disclosed which serves to tunnel information of TCP congestion control dynamics directly from the TCP based transport layer to the data link-layer which selects in response to these information modulation and/or coding schemas to transmit TCP segments via data link-layer blocks with improved TCP throughput.
