  • Patent number: 9706270
    Abstract: A method of routing packets between nodes of a packet switched network, the method comprising receiving a packet at a first node, the packet comprising routing information and payload data, sending said routing information to a second node in the routing path via a first transmission medium having a relatively high transmission speed, and sending said payload data to said second node via a second transmission medium having a relatively low transmission speed. Upon receipt of said routing information, said second node is able to prepare or begin preparation for onward routing of the packet in advance of receipt of said payload.

  • Patent number: 9596140
    Abstract: Methods and nodes for providing radio access to a communication network (314) for mobile terminals (T) at a local site (300). When a local transition unit (304) at the local site receives incoming signals from an antenna (302a) and associated radio head (302b) installed at the local site, the signals are converted into optical form and the local transition unit sends the signals in optical form over an optical link (306) to a central office (308) comprising a set of radio units (312). A central transition unit (310) at the central office converts the signals into a form adapted for reception by a radio unit. The central transition unit is further instructed by a control unit (316) to forward the signals to one of the radio units based on configuration data of the antenna/radio head. The configuration data has been registered at the control unit when received from the antenna/radio head over a control channel automatically at installation.

  • Patent number: 9509605
    Abstract: A method is provided performed by an access point for handling uplink communication in a communication system comprising the access point and a wire line network node connected via wire line to the access point. The method comprises receiving an encrypted and/or integrity protected packet data unit, PDU, from a user equipment (UE) wirelessly connected to the access point and detecting type of the received PDU, the type of PDU being any of a signaling radio bearer type or a data radio bearer type. The method further comprises encapsulating the received PDU by setting a header to the PDU, which header comprises an identity indicating the detected type of PDU and an identity indicating a source address and/or a destination address of the PDU, and sending the encapsulated PDU to the wire line network node. Provided is also a corresponding method performed in the wire line network node.

  • Patent number: 8681945
    Abstract: Method, arrangement and devices for calibration of a line driving device, such as a DSLAM, having a line port. The method comprises deriving of a first parameter vector, PVinf, for example Hinf. The parameter vector PVinf is derived by performing, at a first site, an echo measurement on the line driving device while the line port on said line driving device is open. The method further comprises calibrating the line driving device based on the first parameter vector PVinf and a second parameter vector PVref, which second parameter vector is based on information on echo measurements performed on at least one reference line driving device.

  • Publication number: 20130158922
    Abstract: Method, arrangement and network node/device for estimating a quantity related to impedance in a first frequency interval, D1, of a telecommunication transmission line where the transmission line has a length d. The method involves determining a quantity related to impedance of the telecommunication transmission line for at least two frequencies, f1D2 and f2D2, in a second frequency interval D2. The frequencies f1D2 and f2D2 should fulfil the condition that the line length d times the absolute value of the difference between a line propagation constant ?(f1)D2 and a line propagation constant, ?(f2)D2, is less than ?, i.e. abs(d*?(f1)D2?d*?(f2)D2)<?. The method further involves estimating a quantity related to impedance in the first frequency interval D1 based on the determined quantity related to impedance in the second frequency interval D2, where the estimating involves the fitting of a Puiseux series to the determined quantity related to impedance in frequency interval D2.
