  • Patent number: 8787306
    Abstract: Providing for centralized access management to diverse types of mobile network access points is described herein. By way of example, network components can generate a system determination list (SDL) for a user terminal (UT) that is customized to access capabilities of the UT and/or current position of the UT. The SDL can be employed by the UT to determine which network access points to camp on, handoff to, or the like. The network components can include a network database that maintains UT subscriber and related home Femto cell information, or such information can be maintained at a network operator's home location register. In some aspects, the information can be obtained over the air from the UT or from a base station serving the UT.

  • Publication number: 20140199998
    Abstract: Providing for distributed access point management for access to a mobile network is described herein. By way of example, an interface application maintained at a Femto cell base station (BS) can facilitate initial power up and/or acquisition for a Femto user terminal (UT). Upon start-up, a bootstrap process is utilized by the Femto cell to provision the UT with an SDL establishing at least one BS as high priority within a particular geographic area (GEO). Thus, when the Femto UT is within the GEO, the UT is more likely to acquire, camp on and/or handoff to the preferred BS. When outside the GEO, a serving access point can provision the Femto UT OTA with a custom SDL suited to another GEO having a different high priority access point. By implementing access point management at distributed access points, expensive network equipment can be mitigated or avoided.

  • Patent number: 8781435
    Abstract: Systems and methods for identifying an address of a femto node during handoff of an access terminal from a femto node to a macro node. In one embodiment, the femto node assigns a unique identifier to the access terminal. The access terminal passes the unique identifier to the macro node. The macro node partitions the unique identifier to determine the address of the femto node. In another embodiment, the femto node registers its address with a domain name system. The macro node queries the domain name system to obtain the address of the femto node. In another embodiment, the macro node sends the unique identifier to a proxy. The proxy partitions the unique identifier to determine the address of the femto node.

  • Publication number: 20140094173
    Abstract: Systems and methodologies are described that facilitate distributing and/or utilizing a Closed Subscriber Group (CSG) Identifier (ID) that identifies a CSG corresponding to a base station and a CSG indication that distinguishes between the base station permitting access to members of the CSG and permitting access to members and non-members of the CSG. For instance, the CSG ID can uniquely identify the CSG corresponding to the base station. A mobile device can receive the CSG ID and the CSG indication from the base station. Further, the received CSG ID can be compared to CSG IDs included in an allowed CSG list to recognize whether the mobile device is a member or a non-member of the CSG. Moreover, a preference for selecting the base station as compared to a disparate base station can be generated as a function of the received CSG ID and CSG indication.

  • Publication number: 20140045495
    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: 20140016529
    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: 8477606
    Abstract: A service for Public Safety (PS) and Law Enforcement (LE) users on commercial wireless networks which assure them access to packet data services. The service request is application based. The applications that are for official use, by the PS/LE users, could have a reserved priority level associated with them. The reserved priority level could be higher than a normal commercial user. The network could use the priority to distinguish users, and dynamically allocate and optimize network resources. The network could use priority level information to perform access, admission, and congestion control. The PS/LE user could use the official applications while on duty and un-official ones while off duty, thus, additionally freeing up network resources. The PS/LE users could then use advanced commercial packet data services, without the need for a private network, while at the same time making it feasible for commercial networks.

  • Patent number: 8467304
    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: 20120309394
    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 for disambiguating a target femto node. 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. Additionally, the femto node can broadcast multiple beacons to assist in disambiguation of the target femto node. Also, where complete disambiguation is not possible, the femto gateway can prepare multiple femto nodes for hand-in.
