  • Patent number: 8718018
    Abstract: A user equipment (UE) is provided which reduces uplink signaling overhead in the process of reporting inter-frequency measurement results over a RACH. For measurement reporting, the UE receives an SIB including a cell information list for non-used frequency cells and a threshold from an RNC, compares signal strengths of signals received from the non-used frequency cells with the threshold, and acquires at least one inter-frequency cell ID indicating at least one non-used frequency cell having signal strength exceeding the threshold from the cell information list. The at least one inter-frequency cell ID is included in a RACH message as measurement result information for the at least one non-used frequency cell, and transmitted to the RNC. The RNC determines that the cell corresponding to the inter-frequency cell ID has signal strength exceeding the threshold.

    Abstract: A method and terminal for association update are provided. When the terminal performs location area update to a MSC/VLR via a GERAN/UTRAN, if it has performed combined update or CSFB attachment in an EPS network via E-UTRAN, then it sets a combined update indication which indicates the EPS network requires combined update when the terminal returns to the E-UTRAN from the GERAN/UTRAN; when the terminal moves to a registered tracking area of the E-UTRAN, it determines whether the combined update indication has been set or not, if yes, it initiates combined TAU and LAU to an MME. After receiving a location update request from the MME, the MSC/VLR updates stored association information and re-establishes SGs association with the MME. Accordingly, a terminal has a control module for association update, which comprises a combined update indication setting determination unit, a combined update setting unit and a combined update initiation determination unit.

    Abstract: Methods, apparatuses, and computer program products are disclosed for facilitating a beacon-assisted handover from a macro network to a femto cell during an active call. A femto cell management system assigns a unique identifier to a femto cell, which the femto cell utilizes to broadcast a beacon at a frequency different than the operating frequency of the femto cell. A wireless terminal receives a control message from the macro network directing the wireless terminal to scan particular frequencies. The wireless terminal subsequently provides a report to the macro network identifying attributes ascertained from the scan, which includes attributes associated with the beacon. The macro network then performs a handover from the macro network to the femto cell as a function of the attributes.

The ban signal is based on the acquired base station data and may induce at least one communication device to stop communicating with the targeted base station. In addition, the method includes controlling communications associated with the at least one communication device via the mobile base station mimicking system.

  • Patent number: 8676216
    Abstract: Methods and apparatuses are provided for determining one or more parameters of an access point that can be set or adjusted to mitigate interference to other access points. A rise-over-thermal (RoT) threshold can be set at an access point based on one or more parameters, such as pathloss measurements, location of the access point, etc., such that interference from devices communicating with the access point can be mitigated. In addition, a noise floor, RoT threshold, etc., can be adjusted based on determining a transmit power difference, out-of-cell interference, and/or similar measurements.

  • Patent number: 8676193
    Abstract: Systems and method are presented for a wireless Base Station (BS) of a host Operator to allow access to its Radio Access Network (RAN) by both Subscriber Stations associated with the host Operator and Subscriber Stations associated with other Operators, in which the first set of Subscriber Stations are connected by a general backhaul channel to the host Operator's Core Network data source, and the second set of Subscriber Station are connected by dedicated backhaul channels to Core Network data sources of the other Operators. In this manner, the host Operator provides partial roaming to the second set of Subscriber Stations, which use the host Operators RAN and wireless BS, but not the host Operator's network infrastructure.

  • Patent number: 8676160
    Abstract: A method and an apparatus control a UE that supports a dual mode for controlling power consumption. A wireless local area network (WLAN) modem of a user equipment (UE) automatically turns on when the UE detects that the UE has entered into an area (e.g. home) that employs a home network including a femto Node B and a WLAN access point (AP). The method and apparatus may also determine whether a femto identifier received from a Node B of a home network is an identifier registered in a WLAN turn-on list stored in the UE. If the femto identifier is registered in the WLAN turn-on list, the WLAN modem of the UE is turned on.

  • Patent number: 8676215
    Abstract: A method is provided a wireless system for providing an interference suppression zone in a portion of the macro cell coverage area bordering the small-cell coverage area for a small cell, but outside that small-cell coverage area. The transmission power of a UE located within the interference suppression zone is minimized to minimize the inter-cell interference to the small cells. The invention methodology further operates to enhance the redirection/redistribution methods of the art for UEs located in the interference suppression zone, further reducing macro to small cell interference. In further embodiments of the invention, methods are provided for determining the scope of an interference suppression zone and for determining proximity of an UE to the interference suppression zone.

    Abstract: A method and apparatus for handling a call transfer from a circuit switched access network to a packet switched access network. A Mobile Switching Center Server receives a notification that a call for a terminal requires handover from a circuit switched access network to a packet switched access network. The MSC Server determines whether the terminal is currently registered in an IMS network and/or whether the MSC Server is registered such that it can perform handover from the circuit switched access network to the packet switched access network. If so, then return Single Radio Voice Call Continuity is invoked to perform a handover of the call from the circuit switched access network to the packet switched access network. If not then the MSC Server invokes error handling procedures.
