摘要： The present invention relates to quality-based scheduling of data in wireless networks. In this scheduling, quality information representing the degree of decodability of previously transmitted but not correctly received and not successfully decoded data packets is estimated in receiving communications nodes. This quality information is reported back to the node that transmitted the packet. The quality information will be used by the transmitting node when scheduling subsequent data transmissions. In this scheduling process, at least one of selection of: i) receiving node(s), to which a second data packet is to be forwarded; ii) a type of the data in the second packet; and/or iii) a data flow, to which the second packet belongs, is performed based on the quality information.

摘要： Packets may be routed in a heterogeneous communications network as follows: for a set of packets comprising at least one packet to be transmitted from a sending node, said sending node being able to handle communication according to at least two access technologies,—selecting in a selection unit in the sending node an access technology for use when transmitting the set of packets,—selecting a receiving node in the network to which to transmit the set of packets among nodes in the network that are able to handle said selected access technology—transmitting the set of packets to the selected receiving node using the selected access technology. Alternatively, a set of packets may be transmitted to one or more nodes using at least two different access technologies. Depending on the transmission quality, one node may be selected to forward the set of packets.

摘要： A method implemented in an anchor base station configured performing a proxy operation at an anchor base station in which the anchor base station acts as a proxy between a second S-GW or an MME node and a self-backhauled base station. The method includes receiving a data packet destined for the user equipment and mapping the received data packet from an incoming General Packet Radio Service (GPRS) Tunneling Protocol (GTP) tunnel to an outgoing GTP tunnel. The method also includes receiving a control message and modifying elements of the control message while copying other elements in the control message and forwarding the control message between the self-backhauled base station and the second S-GW or MME node.

摘要： The object of the present invention is to provide a mechanism for a more efficient carrier search. The object is achieved by a method for sending a signal in a first node. The first node communicates with a second node via radio communication, which radio communication is performed by multi carrier transmission. The first node uses a carrier, being associated with a frequency range. The method comprises the step of transmitting an end-marker signal within or close to the frequency range. The end-marker signal is intended to be received and used by the second node for identifying the frequency range of the used carrier.

摘要： A true cross-layer integration of functions is provided on several protocol layers within a network, thus providing a unified approach to Quality of Service (QoS) provisioning in a multihop network. In the unified approach, connections are preferably determined by integrated optimization of a given objective function with respect to connection parameters on at least three protocol layers within the network. Preferably, the optimization involves routing (path selection), channel access as well as adaptation of physical link parameters. By incorporating physical connection parameters together with properly designed constraints, the issue of interference can be carefully considered. It is thereby possible to determine connection parameters that ensure substantially non-interfering communication with respect to existing connections as well as the new connection.

摘要： In accordance with the invention, signal information representative of a first set of information to be transmitted more than one time over at least one link is stored as a priori known signal information. This could be previously received and/or, detected information, own transmitted information or otherwise available relevant signal information in the node. Signal information representative of a second set of information is received, wherein a transmission of the first set of information interferes with the reception of the second set of information. In spite of the interference, at least part of the second set of information can still be successfully be detected by exploiting the received signal information and at least part of the previously stored a priori known signal information. The information is detected by interference cancellation based on the received signal information and relevant parts of the a priori known information. The set of priori known signal information is preferably updated by continuously storing newly detected information.

摘要： A method and apparatus for supporting a purchase of content over a public communication network from a content provider (404) to a customer (400) using an access operator for communication. The content provider receives a purchase request for content from the customer over the public network (102). The requested purchase is validated by a transaction router (406) which identifies the access operator and checks whether the operator approves the requested purchase. The content provider then delivers content to the customer if the purchase has been validated. Finally, the customer can be charged for the purchase by the access operator. The transaction router acts as a common payment mediator between plural operators and content providers, such that only one trusted relationship needs to be established with the transaction router for each operator and each content provider, respectively.
