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： This invention extends routing mechanisms that use link metrics for route selection so that: A link metric cross correlation vector is determined for all links, where each element in the vector corresponds to some other link, and reflects the change in the link metric value if a data flow would already use this other link. The invention further describes a specific embodiment where all cross-correlating links are adjacent to each other, i.e., they terminate or originate in a common node. A mechanism is described to create an extended routing graph. This extended graph permits the use of standard polynomial time algorithms that simultaneously construct the optimal route and find the optimal route metric (such as shortest-path algorithms) also for the adjacent link cross-correlating case.

摘要： The present invention relates to a method and arrangement for making a handover decision in a multi-access communication network comprising a core network (30) and at least one user terminal network (10) communicating with said core network (30) on at least two access paths (a, b) via at least two access networks (20a, 20b), whereby data sessions are routed on at least a first access path (a) via a first access network (20a) and a second access path (b) via a second access network (20b). A first set of criteria is determined by an Access Network control Function (ANF) (25a, 25b) for when a handover between said at least two access paths (a, b) should be performed and a report is sent to an Access Selection Function (ASF) (34) when at least one criterion of said first set of criteria is fulfilled. A second set of criteria is determined by a Connection Management Function (CMF) (14) for when a handover between said at least two access paths (a, b) should be performed and a report is sent to the ASF (34) when at least one criterion of said second set of criteria is fulfilled. The ASF (34) determines one or more data sessions of said at least one user terminal network (10) to be handed over based on the sent reports and directs a core network anchor (32) and a terminal anchor (12) to execute a handover by re-routing said determined data sessions from one access path (a, b) to an alternative access path (a, b).

摘要： The invention is directed towards determining an access node (14, 16) for a terminal (18) in a network (10) having one or more access nodes capable of providing access to the terminal based on one or more access technologies. Access node is selected through determining whether at least one network parameter provided by a network node (12, 14, 16) is required as input for the access node selection for the terminal. If it is determined that the at least one network parameter is required as input, the network parameter is obtained and an access node possibly together with access type for the terminal is selected at least based on said network parameter.

摘要： A wireless relay node (100) comprises a receiving side (110) and a transmitting side (120) adapted for concurrent reception and transmission of an information stream, and at least one of the two sides has multiple antennas for multi-antenna operation. In the internal design, the wireless relay node is further configured (130) for cancelling signal feedback from a multi-antenna dependent feedback channel from the transmitting side to the receiving side based on an N x M dimensional filter matrix (135) dependent on the multi-antenna dependent feedback channel, where at least one of N and M is greater than 1. In this way, self-interference cancellation of a multi-antenna dependent feedback signal from the output to the input of the wireless relay node is effectively obtained.
