  • Publication number: 20130084864
    Abstract: Systems and techniques for handover management in wireless communication networks. An apparatus, such as a base station, receives information relating to load conditions and computes handover threshold information based on the information relating to the load conditions. The information relating to the load conditions may comprise information received from other base stations, and the base station may in turn share its own information. Information may be shared through direct communication between base stations, or may be managed by a controller. Handover thresholds may be set for user devices based on the load metric information.

  • Publication number: 20130084865
    Abstract: Systems and techniques for managing the use of almost blank subframes in wireless communication systems. Base stations in a wireless network monitor load information affecting network nodes. Load information may be in the form of load metric information. The load information may be exchanged between system elements, and an almost blank subframe proportioning may be updated by one or more of the base stations, and information relating to the updated proportioning. The updated almost blank subframe proportioning may be used in scheduling and load metric calculation, as well as almost blank subframe patterning. Updating of almost blank subframe information and load metric information may be performed iteratively.

  • Patent number: 8401574
    Abstract: A method and apparatus for managing delivery of information in a wireless network (100) includes bearer plane information handlers (110, 111), each of which maintains a database of paging controller associations (200). Each paging controller association is an association of an idle mobile device to a last known paging controller of that idle mobile device. The apparatus also includes paging controllers (115-118), each of which is associated with at least one paging area (130-133). For each paging area, the paging controller maintains a database of all base transmitters of the paging area that are associated with the paging controller (310) and maintains a database of other selected paging controllers that control base transmitters in the paging area (315). Using these resources, the method uses location notification messages and paging responses to deliver bearer plane information to a mobile device (125) that has been idle.

  • Patent number: 8374153
    Abstract: Various embodiments are described to enable improved inter-network/inter-technology handover of mobile devices. A network device (131, 132) collects dynamic information corresponding to mobile devices (101, 102), such as wireless measurement information at the device's location, and/or information corresponding to wireless network nodes (121-124), such loading levels/loading distributions. The network device then sends some or all of the dynamic information collected and/or statistical information generated from the dynamic information collected to a neighboring network information server (150) for access by other communication networks. By maintaining dynamic and/or statistical information in a neighboring network information server, such information can be made available to all the communication networks in a given region. One potential benefit to making this information available is improved inter-network handoff decision-making.

  • Publication number: 20120153387
    Abstract: Techniques are disclosed for forming transistor devices having source and drain regions with high concentrations of boron doped germanium. In some embodiments, an in situ boron doped germanium, or alternatively, boron doped silicon germanium capped with a heavily boron doped germanium layer, are provided using selective epitaxial deposition in the source and drain regions and their corresponding tip regions. In some such cases, germanium concentration can be, for example, in excess of 50 atomic % and up to 100 atomic %, and the boron concentration can be, for instance, in excess of 1E20 cm?3. A buffer providing graded germanium and/or boron concentrations can be used to better interface disparate layers. The concentration of boron doped in the germanium at the epi-metal interface effectively lowers parasitic resistance without degrading tip abruptness. The techniques can be embodied, for instance, in planar or non-planar transistor devices.
