  • Patent number: 9338710
    Abstract: A method is implemented in an anchor eNodeB of a network, where the anchor eNodeB communicates with a self-backhauled eNodeB via a radio interface and where the network further includes another eNodeB. The method includes determining whether a user equipment (UE) is being handed off from the first self-backhauled eNodeB to the other eNodeB. The determining is based on: receiving (820) a message from the self-backhauled eNodeB via the radio interface instructing the anchor eNodeB to stop delivering packets that are destined for the UE, or sniffing (1 105, 1 1 10, 1 1 15) into one or more messages sent from the self-backhauled eNodeB to the other eNodeB to identify that the UE is being handed off from the self-backhauled eNodeB to the other eNodeB. The method further includes storing (1 120), based on the determination of whether the UE is being handed off, received packets intended for the UE: and forwarding (1 120) the stored packets to the other eNodeB via a transport network for delivery to the UE.

  • Publication number: 20160105915
    Abstract: The present invention relates to methods and apparatus for enabling an establishment of a connection between a wireless device and a core network via an access node of a standalone LTE RAN using an unlicensed frequency band. The method performed by the access node comprises transmitting a broadcast message in a cell served by the access node. The message indicates that the access node supports connectivity to at least one core network associated with another RAN than the standalone LTE RAN. The method also comprises receiving a request to attach from a wireless device in the cell, for establishing a secure connection for user data between the wireless device and a target core network via the access node. The method further comprises transmitting a request to a target core network node to establish the secure connection.

  • Patent number: 9215615
    Abstract: A method is disclosed that can be performed in at least one network node which provides wireless communications service for user equipment nodes (UEs). The method includes detecting uplink interference at an interfered network node. Responsive to the uplink interference, an uplink transmission having a defined configuration is initiated from a UE, which is served by a serving network node. The uplink signal is detected using the defined configuration at the interfered network node. The UE is identified responsive to the detected uplink signal as being a contributor to the uplink interference. An uplink transmission by the UE and/or by another UE served by the serving network node is controlled to reduce uplink interference.

  • Publication number: 20150334566
    Abstract: There is provided a method of authenticating a public land mobile network (PLMN) to a mobile station (MS). The PLMN provides a circuit switched access network to the MS, and the MS and a trusted service, TS, have established a security context. The initiation of a voice call or initiation of sending or receiving of a pushed message by the MS (S10.1) is detected, and the TS generates a response authentication token using a session identifier and the security context (S10.7). The TS sends a response comprising the response authentication token to the MS such that the response is delivered to the MS over a signalling channel of the PLMN using a mobile subscriber integrated services digital network-number (MSISDN) associated with the subscriber or subscription to direct the message (S10.9). The MS authenticates the response using the response authentication token, the security context, and the session identifier (S10.12) in order to authenticate the PLMN.

  • Patent number: 9191851
    Abstract: A telecommunications node (28) comprises a communication interface (36) and a parameter controller (40). The node (28) acquires timing advance (TA) information and angle of arrival (AoA) information through the communication interface (36). The timing advance (TA) information and angle of arrival (AoA) information are based on uplink signals received over a radio interface (32) from one or more wireless terminals (30) that are involved or have been involved in handover. The parameter controller (40) uses the timing advance (TA) information and the angle of arrival (AoA) information to make a determination of size and shape of a cell of a radio access network.

  • Publication number: 20150312383
    Abstract: A method and apparatus for handling Multipath Transmission Control Protocol, MPTCP, signaling in a communications network. The communications network includes a first node hosting an MPTCP proxy function, and a second node in a second access network. The second node receives from a mobile terminal an attachment request. The second node then sends a message to a remote database and receives a response, the response including an identity of the first node. An MPTCP data path can then be redirected from the second access network to the MPTCP proxy function. Even in cases where the MPTCP proxy function is located at or between the PDN Gateway and the mobile terminal, the second access can be made aware of the location of the MPTCP proxy function and route MPTCP data traffic accordingly.
