Abstract: Embodiments analyze crowd-sourced data to identify a moved or moving beacon. The crowd-sourced data for the beacon is grouped into a plurality of clusters based on spatial distance. Timestamps associated with the crowd-sourced data in the clusters are compared to select one of the clusters. The crowd-sourced data associated with the selected cluster is used to determine position information for the beacon.

Abstract: The present invention relates to a method and an arrangement in a communication network node (15) of achieving an optimal initial shaping rate for a new packet flow on a transport network between said communication network node (15) and a second communication network node (10) in a communication network system. The shaping rates of ongoing packet flows on said transport network are determined. And, based on said determined shaping rates of ongoing packet flows, an initial shaping rate for said new packet flow is selected so as to obtain a maximized fairness among all shaping rates.

Abstract: There is proposed a network system and the like achieving a packet relay transmission with high relay transmission efficiency according to Intermittent Periodic Transmit method (IPT). In order to achieve Intermittent Periodic Transmit in a mesh cluster, a communication control unit of a core node selects one of a plurality of communication units according to downlink priority and causes the selected communication unit to transmit a packet with a periodic interval. In order to transmit a packet from the core node to another slave node, a communication control unit of a slave node selects one of the communication units according to downlink priority, and in order to transmit a packet from a slave node to the core node, the communication control unit of the slave node selects one of the communication units according to uplink priority. Then, the communication control unit causes the selected communication unit to transmit the packet.

Abstract: Systems and methods of delegating a proxy node for content delivery to a wireless device are provided. A wireless device authenticates with a proxy node, and the proxy node provides to the wireless device a list of content stored on a first content node. If the wireless device requests a second content stored on a second content node, the second content node sends an attachment request to the proxy node, the proxy node associates the second content node with the proxy node, and the proxy node delivers the second content to the wireless device.

Abstract: Methods and apparatuses are disclosed that provide flexible use of a shared radio resource. An apparatus determines from monitoring signal energy on a shared radio resource whether other transmitters are present. A predetermined set of time division duplex (TDD) signaling patterns are identified. A correlation is performed between signal energy received on the shared radio resource and the predetermined TDD signaling patterns. The apparatus may then determine a TDD signaling pattern that may reduce or avoid interference with any other transmitters using the shared resource. The shared radio resource may be, for example, a shared frequency spectrum. Efficient allocation of radio resources among apparatuses such as radio transceivers, without fixed time references or predetermined patterns, may be obtained. The radio transceivers may be base stations or mobile user equipment in a wireless communications system. The apparatus may be an integrated circuit, a portion thereof, or chipset.

Abstract: A system and method for efficient transfer of backup data over multiple networks. A backup server and a client computer are coupled to one another via a network, such as a local area network (LAN). The backup server is coupled to at least one storage server via another network, such as the Internet. This storage server is coupled to another storage server via at least two networks, such as the Internet and a Fiber Channel connection. The at least two networks are discovered and initialized by the two storage servers. Two or more networks may be bonded together in a single logical communication channel for transferring backup data. In one embodiment, the backup data corresponds to a duplication operation. When two or more network channels are included in the logical communication channel, a load balancing scheme is used to assign backup data traffic to appropriate network channels.

Abstract: A method of optimizing scanning parameters for a plurality of channels in a wireless band includes identifying channels in the plurality of channels as overlapping channels and identifying channels in the plurality of channels as non-overlapping channels, wherein each of the non-overlapping channels transmits and receives signals at frequencies that do not overlap frequencies of other non-overlapping channels. Then scanning parameters for each channel are optimized in order to assign the scanning parameters to be normal scanning parameters or extended scanning parameters, the extended scanning parameters indicating longer scanning times used for scanning channels than that of the normal scanning parameters. Next each overlapping channel is scanned with a networked electronic device using the normal scanning parameters. The method also includes scanning each non-overlapping channel with the networked electronic device using the extended scanning parameters.

Abstract: In network-based uplink scheduling, users are scheduled by the network for uplink communication between a user side and a network side. In this context, the invention provides an efficient estimation of User Equipment (UE) buffer status on the network side such as at Node B (20), for each of a number of users (10), and determines an uplink scheduling priority order of the users based on the network-estimated buffer status information. The users (10) are allocated communication resources based on the determined uplink scheduling priority order. In this way, the UE buffer status may be considered in the uplink scheduling procedure without explicit UE buffer status reports (that would waste valuable uplink transmission resources) from the UE side. This means that efficient scheduling and optimal exploitation of the uplink transmission resources are ensured, with clearly improved system performance as a result.

Abstract: A method of performing congestion notification for a data transmission (10) from a sender (14) to a receiver (11) is described. Furthermore, nodes for such a transmission as well as methods of controlling such nodes are described. The data transmission involves a first node (12) and a second node (13) between said sender and receiver. The data packets pass from said second node to said first node towards said receiver. The method comprises: —sending (S82) a message (15) from said first node to said second node, said message relating to a decision on whether to notify said receiver of a congestion condition in said data transmission, —sending (S83) an explicit congestion notification (16) from said second node to said receiver if it is decided to notify said receiver of said congestion condition.
