  • Publication number: 20170215228
    Abstract: Methods and apparatuses are provided for causing active hand-in of a device from a macrocell base station to a femto node, which can be an inter-frequency hand-in. The femto node can broadcast a beacon, which can be received and reported by a device to a source base station along with one or more parameters. The source base station can communicate a handover message to the femto node or a related femto gateway along with the one or more parameters. The femto node or femto gateway can disambiguate the intended target femto node based in part on the one or more parameters, which can include applying one or more filters. Applying the one or more filters may include applying an UL RSSI filter to the one or more femto nodes to determine whether presence of the device causes a rise in UL RSSI measured at the one or more femto nodes.

  • Patent number: 9717064
    Abstract: Methods and apparatuses are provided for avoiding membership verification for a non-closed subscriber group (CSG) user equipment (UE) communicating with a femto node advertising restricted access. A femto node or femto gateway can receive configuration information specifying to refrain from performing membership verification for UEs communicating with a femto node. Based on such information, the femto node or femto gateway can communicate registration information for a registration request received from a non-CSG UE without performing membership verification. Additionally or alternatively, femto nodes can register non-CSG UEs as CSG UEs to mitigate membership verification at femto gateways, request that femto gateways refrain from performing membership verification, and/or the like. In this regard, the femto node can use restricted access parameters for purposes other than restricting access.

  • Patent number: 9699712
    Abstract: Systems and methodologies are described that facilitate communicating PSC split information regarding neighboring cells. The PSC split information can be transmitted in one or more overhead messages selected based on network deployment. Where macro cells and femto cells provide PSC split information, which can be a PSC range for related cells, PSC list, etc., the information can be transmitted in a low priority overhead message since it can be obtained at a source cell. Where only femto cells or closed subscriber group (CSG) cells provide PSC split information, the information can be transmitted in a higher priority more frequently transmitted message. In this regard, the information is available at target cells since not all devices can access CSG cells. Thus, by providing the PSC split information in a more frequently transmitted message, devices can retrieve the PSC split information early on in communications to lower power consumption.

  • Patent number: 9681262
    Abstract: Techniques for supporting location services for a home Node B (HNB) and its user equipments (UEs) are disclosed. In an aspect, location services may be supported for a UE by having an HNB inter-work between user plane and control plane location solutions. In one design, the HNB receives a request for a location service for the UE and communicates (i) with a location server via the user plane location solution and (ii) with the UE via the control plane location solution to support the location service for the UE. The HNB inter-works between the user plane and control plane location solutions. In another aspect, a location server may be used to support assisted GNSS (A-GNSS) for HNBs and UEs. In one design, an HNB exchanges PCAP messages with the location server via an HNB GW and exchanges RRC messages with a UE to support a location service for the UE.

  • Patent number: 9641818
    Abstract: A digital camera is configured to display a continually updated preview image of an observed scene, wherein kinetic objects that appear in the observed scene do not appear in the continually updated preview image. An observed scene includes static objects and kinetic objects. The observed scene is recorded using a digital imaging sensor which forms part of a smartphone. A live camera feed results, the live camera feed comprising a plurality of frames, each depicting the observed scene at a specific time. A median color value is evaluated over m non-consecutive frames captured from the live camera feed. The median color values are used to generate an output feed that is displayed at a reduced frame rate as compared to the live camera feed. The resulting displayed scene includes the same static objects which appeared in the observed scene, but does not include the kinetic objects.

  • Patent number: 9609555
    Abstract: According to some wireless network standards the size of a neighbor cell list is restricted to a maximum size. The limited size of a neighbor cell list may not reflect the realities of a wireless network deployment, especially for deployments including numerous femto cells clustered in close proximity. Accordingly, as the concentration of macro cells and/or femto cells in an area increases, there lies a challenge to identify and communicate neighbor lists to user devices that reflect the arrangement of a particular portion of the deployment and the needs of the user devices. Various systems, methods and apparatus described herein are configured to provide a user device or a group of user devices a neighbor cell list that includes neighbor cell identifiers chosen from a candidate list.

  • Patent number: 9491672
    Abstract: A timer parameter used for transitioning between radio protocol states is adapted based on a change of a handover parameter. For example, as a direct result of a change in a handover parameter such as time-to-trigger, offset, or hysteresis, an inactivity timer that is used for switching an access terminal from a connected state to an idle state may be adapted. As another example, as a direct result of a change in a handover parameter, a radio link failure (RLF) timer that is used for switching an access terminal to an RLF state may be adapted.

  • Publication number: 20160205607
    Abstract: Systems and methods for handling undesirable inter-frequency cell changes are disclosed. A small cell base station receives a request to perform a cell change of a user equipment (UE) from a base station serving the UE to the small cell base station, wherein the base station serving the UE is operating on a different frequency than the small cell base station, receives, from the base station, parameters related to one or more previous cell changes performed by the UE, and determines whether or not the cell change is desirable based on the parameters related to the one or more previous cell changes.
