  • IMS network identity management
    Patent number: 8499340
    Abstract: Methods and apparatus for enabling secure communications between a UE (user equipment) device operating though a packet-switched network and a 3rd party service outside of the user's home domain. The packet-switched network may be, for example, configured according and IMS architecture and use SIP control signaling. An identity server in the user's home domain is coupled with a proxy server or gateway and receives control messages, on which the identity server effects identity translation if needed. Translating messages targeted for the third party serve includes stripping user identifying information and adding a domain identifier to the message. It may also include adding an identity token. Where an identity token is not added, it may be provided upon request to a 3rd party service entity. Translating messages targeted for the UE includes adding a user identifier for home domain routing.

    Abstract: The method an apparatus described herein manages uplink resources to increase spectral efficiency and system capacity. According to one embodiment of the present invention, a base station may be assigned two or more downlink carriers for downlink transmission and two or more corresponding uplink carriers. In a multi-carrier mode, the base station may transmit signals on two or more downlink carriers to the same mobile terminal, and receive signals from the mobile terminal on one of the paired uplink terminals. The uplink carriers can be operated at different interference levels and the uplink traffic can be divided between the available uplink carriers based on the type of traffic and/or data transmission parameters. The mobile terminals may also be allowed to switch between the uplink carriers to improve overall efficiency.

  • Methods and Systems for Enabling User Activity-Aware Positioning
    Publication number: 20130190006
    Abstract: Techniques for using user equipment, UE, activity information, e.g., by a network node in a communications network are described. The network node can obtain the UE activity information, i.e., information associated with at least one of transmission activity and reception activity for a UE, and then use the UE activity information to configure a positioning function. Some examples of the positioning function are positioning method selection, measurement configuration and assistance data provisioning, reserving positioning resources, stopping the positioning session, delaying handover of the UE, deciding on a position session organization such as number of parallel measurements to be performed, and estimating an impact on battery lifetime.

  • Uplink Traffic Separation in an Edge Node of a Communication Network
    Publication number: 20130188491
    Abstract: For separating data traffic in an uplink (UL) edge node (100) of a communication network, UL one or more packet filters (110) are provided in the UL edge node (100). The packet filters (110) identify data packets in UL traffic from the UL edge node (100). Gating data associated with the packet filters (110) are evaluated, e.g. to derive gating control signals (GC1, GC2, GC3) of the individual packet filters (110). Depending on the evaluation of the gating data, the identified data packets are discarded.

  • DETECTION METHOD USING AN ELECTROCHEMICALLY-ASSISTED ALPHA DETECTOR FOR NUCLEAR MEASUREMENT IN A LIQUID MEDIUM
    Publication number: 20130186762
    Abstract: An in situ method for detecting alpha particles contained in a liquid medium, which uses a system which includes a counter-electrode and an alpha particle detector including a substrate made of an intrinsic semiconductor material sandwiched between two electrical contacts, wherein the contact intended to be in contact with the liquid medium is made of boron-doped diamond. By forming a particular electrolyte 8 and by causing a current to flow between counter-electrode and the boron-doped diamond contact in contact with the liquid medium, actinides or polonium present in the liquid medium may be concentrated on the boron-doped diamond contact, and by this means the detection limit of the alpha emitters may be lowered.

  • DETECTION OF EARLY INTER-RADIO ACCESS TECHNOLOGY (IRAT) HANDOVER TRIGGERING
    Publication number: 20130189988
    Abstract: A device detects poor coverage associated with a source radio access technology (RAT) with which the device is connected, and connects to a target RAT. The device also measures the source RAT for a time period after connecting to the target RAT, and sends, based on the measurements, one or more measurement reports to the target RAT, where the target RAT forwards the one or more measurement reports to the source RAT. Alternatively, or additionally, the target RAT may detect that the handover was triggered too early and may inform the source RAT or command the UE to return to the source RAT. The device further stops the measuring and the sending when the time period expires. In this way, IRAT handover parameters may be automatically or manually tuned to minimize the number of handovers triggered too early, which may result in a more efficient cell configuration.
