  • Network Node, Methods Therein, Computer Programs and Computer-Readable Mediums Comprising the Computer Programs, for Keeping Wireless Devices in Active Mode
    Publication number: 20170367048
    Abstract: Method performed by a network node (110) for keeping wireless devices (140) served by the network node (110) in active mode. Each of the wireless devices has a value for a first condition. The network node (110) determines whether each of the wireless devices has the value for the first condition among a number of highest values for the first condition. The first condition is associated with a need to be in active mode. The number of highest values for the first condition corresponds to a maximum amount of wireless devices allowed to be in the active mode simultaneously. The network node (110) updates a register, so that the wireless devices (140) in the register have the highest values for the first condition, according to the maximum amount. The network node (110) keeps the wireless devices (140) in the updated register in active mode.

  • Method and device for improving the transmission efficiency in a communication system with a layered protocol stack
    Patent number: 9800687
    Abstract: In a method for improving the transmission efficiency in a communication system with a layered protocol stack, data packets are processed on an upper protocol layer. Data packets are forwarded to a lower protocol layer for transmission and the transmission is performed with variable channel access delays. The upper protocol layer is notified by the lower protocol layer when a transmission is started to allow a synchronization of timers in the upper protocol layer. If a layer performs a scheduling of data packets for the transmission, a rescheduling is performed alternatively or in addition during a channel access delay. Devices and software programs embodying the invention are also described.

  • Systems and methods for selecting a network access system
    Patent number: 9681362
    Abstract: A system according to some embodiments of the invention includes (1) a component (e.g. ANDSF) that provides a cell selection rule to a UE and (2) a component (e.g. an access node) that provides the UE with information about the load in the cell currently utilized by the UE. This enables the UE to determine whether to leave the cell, which may be a 3GPP cell, and use a different cell, which may be a non-3GPP cell, by applying the cell selection rule in conjunction with its knowledge about the load of the cell.

  • Method and arrangement for route cost determination and selection with link cost interaction
    Patent number: 9674073
    Abstract: 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.
