  • Patent number: 9913206
    Abstract: A method and apparatus for searching for closed subscriber group (CSG) cells are described. A wireless transmit/receive unit (WTRU) transmits, to a network of CSG cells, a measurement/cell-search gap request message including a cause value having at least one bit that indicates whether the request message was transmitted due to a manual cell search command or a WTRU autonomous determination. The WTRU receives a measurement/cell-search gap allocation message from the network in response to the measurement/cell-search request message. The WTRU also may determine whether it has a discontinuous reception (DRX) gap that is long enough to read a master information block (MIB) and a system information block (SIB) of a neighboring CSG cell. If the DRX gap is not long enough, the WTRU may transmit a measurement/cell-search gap request message to the network, or autonomously tune away from a cell currently serving the WTRU to read the MIB and SIB.

    Abstract: A handover proactive association clearing support method and system supports minimizing handover times for at least one netsurfing end system, and optimizing a given market satisfaction function (MSF0) potentially depending on Internet-applications for whichever underlying HO technique, by potentially establishing pre-HO for free x/yz-, netsurfing x/yz-, and/or Sxyzj-association, called “clearing” them. An HO of an Ayz is optimal if its HO-time is “basically zero” and it complies with MSF0. The technical innovation of the method and system comprises for an Ayz determining any time its optimal HOs. This permanent predetermination of optimal HOs implies assessing permanently all parameters. Thus, when an Ayz must perform an HO, these pre-HO operations of the method/system would have already identified at least one optimal HO for it to a sharedIADx and/or an Sxyzj available to it and established the resp. x/yz-, netsurfing x/yz-, and Sxyzj-associations.

  • Patent number: 9351202
    Abstract: A method and an apparatus for serving high speed downlink shared channel (HS-DSCH) cell change are disclosed. A wireless transmit/receive unit (WTRU) receives pre-configured serving cell information for a target cell. The WTRU reports a measurement report and starts monitoring a high speed shared control channel (HS-SCCH) on the target cell. The WTRU may receive an HS-SCCH order over the target cell and/or a radio resource control (RRC) reconfiguration message over a source cell indicating a serving HS-DSCH cell change to the target cell. The WTRU may act upon all information elements of the RRC reconfiguration message in case that the RRC reconfiguration message is received prior to the HS-SCCH order, and act upon the pre-configured serving cell information in case that the HS-SCCH order is received prior to the RRC reconfiguration message.

  • Patent number: 9326268
    Abstract: The various embodiments include methods for managing how a DSDS mobile communication device that is accessing an arbitrary combination of any two mobile telephony networks processes paging collisions. The embodiment methods promote the control of the paging block rates for two distinct subscriptions, in which a subscription's paging block rate is the long-term percentage of its blocked paging messages over its total number of received paging messages. In the various embodiments, a mobile communication device may use a paging blocking bias to achieve a particular paging blocking rate. The paging blocking bias may be set or adjusted through various means to cause a first subscription to have a paging blocking rate that is less than, equal to, or greater than a paging blocking rate for a second subscription.

  • Patent number: 9319995
    Abstract: The present invention relates to a method and an apparatus for controlling the transmit power of a mobile station (UEX) served by a small cell (C1). In accordance with an embodiment of the invention, the method comprises the steps of, and the apparatus comprises means for, detecting a measurement event anticipating the forthcoming fulfillment of a handover condition towards a neighboring macro cell (C2) by the mobile station, and thereupon step-wise increasing the transmit power level of the mobile station so as to reach a transmit power target (P_Target) when the handover condition is eventually fulfilled by the mobile station. The transmit power target is for compensating for an estimated downlink path loss for the mobile station in the macro cell.

  • Patent number: 9215643
    Abstract: A mobile radio communication system having one or more relay stations and base stations, a gateway, an external device having a route selection function, and a policy control device which selects a main route and a sub route on the basis of residual resources in a radio communication device. The mobile station connected to one radio communication device can select another radio communication device having a large amount of residual resources as a new access point when the one radio communication device cannot be used, to prevent shortage of the radio resources. Also, it is possible to enable a process of selecting the radio communication device as a new access point to be omitted when switching one route to another by determining a sub route as the new access point when a main route is disconnected in advance, to shorten a service disconnection time.
