摘要： Systems, methods, and devices are described for supporting macrocell-to-femtocell hand-ins of active macro communications for mobile devices. An out-of-band (OOB) link is used to detect that a mobile device is in proximity of a femtocell. Having detected the mobile device in proximity to the femtocell, an OOB proximity detection is communicated to a femtocell gateway disposed in a core network in communication with the macro network to effectively pre-register the mobile device with the femto-convergence system. When the femtocell gateway receives a handover request from the macro network implicating the pre-registered mobile device, it is able to reliably determine the appropriate target femtocell to use for the hand-in according to the pre-registration, even where identification of the appropriate target femtocell would otherwise be unreliable. Some embodiments may also handling registering the mobile device after a handover request has occurred, including tiered approaches.

摘要： Systems, methods, devices, and computer program products are described for supporting macrocell-to-femtocell hand-ins of active macrocell communications for a mobile device. A mobile device may perform an out-of-band (OOB) search for the femtocell, the OOB search triggered by a proximity detection configuration command from the macrocell. The mobile device may wirelessly communicate with a located femtocell via an OOB link, and receive femtocell information from the femtocell via the OOB link. The mobile device may transmit the received femtocell information to the macrocell. The macrocell may generate instruction for a mobile device search based on the femtocell information. The macrocell may transmit such instructions to the mobile device for an in-band search for the femtocell.

摘要： 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.

摘要： Methods and apparatus for performing femto cell access and paging control for a wireless access terminal (e.g. a cell phone handset) within a network of multiple femto cell components (e.g. HNBs) and an access control component (e.g. a mobile operator's core network). One method comprises storing a first group association of femto cells, using common characteristic (e.g. a Closed Subscriber Group ID), storing a second group association among access terminals (e.g. defining which access terminals belong to which Closed Subscriber Group), and authorizing access to an access terminal to all of the femto cell components belonging to the first group. The access terminal may receive pages from any or all of the femto cells belonging to the group. Residential and enterprise deployments may be co-located.
