Sustainable Wireless Broadband Access to the Future Internet - The EARTH Project

Abstract: In a world of continuous growth of economies and global population eco-sustainability is of outmost relevance. Especially, mobile broadband networks are facing an exponential growing traffic volume and so the sustainability of these networks comes into focus. The recently completed European funded Seventh Framework Programme (FP7) project EARTH has studied the impact of traffic growth on mobile broadband network energy consumption and carbon footprint, pioneering this field. This chapter summarizes the key insights of EARTH on questions like ”How does the exploding traffic impact the sustainability?”, ”How can energy efficiency be rated and predicted?”, ”What are the key solutions to improve the energy efficiency and how to efficiently integrate such solutions?” The results are representing the foundation of the maturing scientific engineering discipline of Energy Efficient Wireless Access, targeting the standardisation in IETF and 3GPP, strongly influencing academic research trends, and will soon be reflected in products and deployments of the European telecommunications industry.

Methods, Device and Node for DRX of Data

Abstract: A method performed by a radio communication device for discontinuous reception, DRX, of data from a radio network node is disclosed. When information, indicating that data is scheduled to the radio communication device in a DRX cycle, is received ( 102, 104 (Y)) during an initial part of a DRX cycle, a receiver of the radio communication device is activated ( 110 ) at the time data is received and deactivated ( 110 ) when data is not received. When information is not received ( 104 (N)) or when the information indicates that no data is scheduled ( 108 (N)) during a remaining part of the DRX cycle, the receiver is kept ( 106 ) deactivated. A method performed by the radio network node for enabling DRX of data by the radio communication device is disclosed, as well as the radio communication device and the radio network node. Micro sleep during single time slices, such as time slots, is enabled.

Radio traffic detector, network node and methods for assisting handover

Abstract: It is presented a method arranged to assist a determination of mobile devices being candidates for handover. The method is performed in a radio traffic detector and comprises: measuring a received signal strength value on a predetermined frequency band; repeating the measuring during a time period; generating a message comprising a timestamp associated with the time period, and a plurality of message elements, wherein each message element is based on a respective received signal strength value for respectively different time instances within the time period; and transmitting the message to a network node to assist the determination of mobile devices being candidates for handover. By using measured received signal strength, uplink traffic can be detected without the need to decode the signals. Corresponding radio traffic device, network node and method are also presented.

Handling of information related to off-line base stations

Abstract: A method is provided in an access point (800) in a wireless communication system. When the access point temporarily does not have an operational backhaul connection (601),the access point receives information from a terminal. The access point provides the information to a messenger (604;605) for mechanical relaying to a service area of an access point having an operational backhaul connection.

Technique for providing content via a mobile communications network

Abstract: A technique of providing content via a mobile communications network to a user terminal is described. A method aspect of this technique comprises assigning, in a connection setup phase initiated by the user terminal, a content access limitation to the user terminal. The content access limitation restricts content access by the user terminal to content predefined on a network side. The method further comprises providing the predefined content to the user terminal. The method may be performed in connection with providing location-dependent information, such as map information, to the user terminal even when the user terminal cannot be authenticated in the mobile communications network.
