  • Publication number: 20120238268
    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 over an operating frequency of the macrocell base station, and the macrocell base station, and/or one or more network components, can identify the femto node based on one or more parameters reported by the device from receiving the beacon. The beacon can be transmitted at varying powers to ensure active hand-in triggering, mitigate interference and/or can be powered on and off for such purposes. In addition, a macrocell base station can regulate compressed mode periods during which a device can measure the femto node based on receiving information regarding device proximity to the femto node, or a device can generate proximity indication messages base on measuring the beacon signals, etc.

  • Publication number: 20110256875
    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.

  • Publication number: 20100120426
    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.

  • Publication number: 20100035601
    Abstract: Mobile user equipment (MUE) can be enabled to search for and camp on a preferred node, such as a home base node (HBN), in a battery-efficient manner even when currently camped on another node, such as a macro base node (MBN). When the MBN provides good channel quality, slow rate background intra- and inter-frequency searches can discover the preferred HBN that would otherwise not be discovered or would consume excessive power with continual searching. When channel quality is fair, slow rate background inter-frequency searches can result in timely switching to the preferred HBN. Location hints that indicate proximity of the preferred HBN can be used to trigger slow rate background searches. Neighboring cell searching of neighbor cell listing (NCL) when in channel quality is fair or poor are maintained to prepare for call reselections to available node.

  • Publication number: 20100029274
    Abstract: Systems and methodologies are described herein that facilitate improved cell search and selection in a wireless communication system. For example, a terminal as described herein can utilize one or more Closed Subscriber Group (CSG)-specific offset and/or hysteresis parameters as described herein to increase the amount of time on which the terminal is allowed to camp on a desirable cell. Additionally, specialized reselection timing can be employed as described herein to increase a delay associated with selecting a Home Node B (HNB) or Home Evolved Node B (HeNB) cell, thereby reducing power consumption associated with rapid cell reselection operations in a densely populated network environment. Further, a two-step reselection process can be performed as described herein in the context of selecting a frequency for cell reselection, thereby mitigating the effects of rapid reselection between cells and/or frequencies due to CSG cell prioritization.

  • Publication number: 20100027510
    Abstract: Systems and methodologies are described that facilitate performing idle handoff in a wireless communication environment. Signal quality of a pilot received from a base station can be measured, and a type (e.g., femto, macro, . . . ) of the base station from which the pilot is received can be identified. According to an example, when the type of the base station is identified as being a femto cell base station, the base station can be recognized as being either preferred or non-preferred. Further, a linger timer can be initiated when the signal quality of the pilot exceeds an entry threshold and the base station is identified as a femto cell base station. Moreover, idle handoff to the base station can be performed upon expiration of the linger timer as a function of at least one subsequent measurement of signal quality of the pilot received from the base station.

  • Publication number: 20100008323
    Abstract: A femto cell neighbor list message for a wireless communication system that includes the frequencies and pseudonoise offsets reserved for macro cells and femto cells is disclosed. When the user equipment discovers the femto cell, the user equipment can read the Femto Cell Identification Message and present the identification information to the subscriber. In absence of this knowledge, a manual femto cell search must search all frequencies and all pseudonoise offsets resulting in lengthy search times.

  • Publication number: 20090316649
    Abstract: Systems and methodologies are described that facilitate automatically configuring femtocells based at least in part on signals transmitted by other femtocells and macrocells. In particular, a femtocell can receive signals from neighboring cells, much like a mobile device, and determine communications parameters used. The parameters can be channel identifiers, pseudo-noise (PN) offsets, and the like. The femtocell can subsequently configure its communication parameters to vary from those detected in the neighboring signals, or to match those of neighboring signals where the parameters relate to the communications environment, for example. Thus, the femtocell self-configures to mitigate interference with surrounding femtocells and/or macrocells.

  • Publication number: 20090247170
    Abstract: Cellular network may introduce a large number of limited access/limited range (“small”) base stations deployed by end-users such as home base nodes (HNBs) or Femtocells that provide access to access terminals (ATs) or user equipment (UE) to a core network. A selective discovery approach enables UE to discover and to use a small base station without wasting power to discover an alien base station or to search when not within range of any open small base station. Discovery can entail location-dependent determination (e.g., macro base station triangulation, global positioning system, local broadcast channel, etc.) of being within range of an open femtocell whose identity was manually learned, accessed via a distributed neighbor list, etc. The UE can advantageously tolerate small changes in location without having to relearn the identity of the femtocell. The type of access afforded is advantageously communicated to end user via a display indicator.

  • Publication number: 20090238114
    Abstract: Systems and methodologies are described that facilitate cell search, selection, and reselection within a wireless communication network that includes a home node base station (home nodeB). A user equipment (UE) can detect a home nodeB and communicate such identification to a macro network that includes at least one node base station (nodeB). The detected home nodeB and nodeB can be hierarchically structured in order to prioritize connectivity with the home nodeB over the nodeB. Such prioritization can be implemented by broadcasting home nodeB parameters and macro nodeB parameters having identification information therewith.
