  • Publication number: 20170257904
    Abstract: An access node (620) of the cellular network determines a correlation of an identifier of a user equipment (610) with an entry of a Pending Interest Table maintained by an Information Centric Networking node (670). The Pending Interest Table comprises an entry for each data object having a pending Information Centric Networking request (801) at the Information Centric Networking node (670). Based on the correlation, the access node (620) controls a connection of the user equipment (610) with the cellular network. This may involve deciding whether to release the user equipment (610) to idle mode or paging of the user equipment (610).

  • Publication number: 20170245228
    Abstract: A method (100, 200) in a synchronisation control unit is disclosed. The method enables synchronisation of a plurality of distributed devices with a network and comprises the steps of receiving a wireless synchronisation signal from a network node over a wireless channel (104, 204) and processing the received synchronisation signal (108, 208). The method further comprises transmitting the processed synchronisation signal to the plurality of distributed devices over a local connection which is different to the wireless channel over which the wireless synchronisation channel is received (120, 220). Also disclosed are a synchronisation control unit (300, 400) and a computer program product.

  • Publication number: 20170099685
    Abstract: The present disclosure relates to devices and methods for establishing and maintaining backhaul connections between small cell radio base stations and a core network. In particular it relates to methods using a client to manage the backhaul connection. According to one aspect, the method relates to receiving, from the small cell RBS, at least one message triggering the establishment of the wireless backhaul connection between the small cell RBS and the core network. The method further comprises deriving, from the at least one message, base station property information of the small cell RBS. The method further comprises sending, to a core network node, a connectivity request message, including the derived base station property information thereby enabling a selection of a packet gateway and/or a configuration for the small cell RBS in the establishment of the wireless backhaul connection.

  • Publication number: 20170055304
    Abstract: There is provided means for connecting a client node to a hub node in a wireless backhaul network. Network related operations, administration, and maintenance (OAM) system information is acquired by the client node. A wireless connection is established by the client node to a hub node. The hub node is selected based on the acquired OAM system information. A start up procedure for connecting the client node to the hub node is thereby provided.

  • Patent number: 9572158
    Abstract: Method and residential control node for enabling encrypted residential communication of user data between two wireless communication devices. The method comprises receiving a radio bearer mapping from a communication network node, establishing a connection with a first wireless communication device, in accordance with the radio bearer mapping, and establishing a connection with a second wireless communication device, in accordance with the radio bearer mapping. Furthermore, the method comprises obtaining a first key which is based on a key of the first wireless communication device, from the communication network node, and obtaining a second key which is based on a key of the second wireless communication device. Thereby, the residential control node is enabled to decrypt user data received from the first wireless communication device by the first key, and encrypting the user data by the second key, before sending the user data to the second wireless communication device.

  • Publication number: 20160309389
    Abstract: Embodiments presented herein relate to bearer handling, and particularly to a method, a network node, a computer program, and a computer program product for flexible bearer handling in a communications network. Packet data convergence protocol (PDCP) protocol data units (PDUs) are acquired. Individual PDCP PDUs are encapsulated into individual frames at at least one protocol layer above a bottom-most protocol layer. The individual frames are switched towards a packet switched network.

  • Patent number: 9009017
    Abstract: Embodiments of the present invention relate to an arrangement for analyzing transmission line properties. Measurement data providing means provide data of a first frequency dependent line property, line property calculation arrangement with model handling means, a Hubert transform handler and line property determination means calculate said first property based on model parameters, line resistance at 0 frequency, roc, a cut-off frequency, v, a line capacitance C? and a line inductance L?H. The line model handling means calculates the line inductance L(f) via a Hubert transform of a function of Q(f/v), wherein the function Q(f/v) relates the line resistance R(f) to roc as R(f)=roc·Q(f/v). The Hilbert transform values are calculated using a parameterized closed form expression for the Hubert transform or they are tabulated.
