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.

Aspects are disclosed for facilitating a hand-in to a femto cell. An identifier is assigned to a femto cell in which the identifier is based on a scrambling parameter and a timing parameter. A relationship between the identifier and the femto cell is then communicated. In another embodiment, a user equipment report is received, which includes attributes related to a signal broadcast by a femto cell. An identifier associated with the femto cell is ascertained from an attribute included in the report. The femto cell is then identified based on the identifier. In a further embodiment, a timing parameter is received, and a scrambling parameter is set. A signal including the scrambling parameter is then broadcast according to an offset related to the timing parameter. In yet another embodiment, a femto cell is detected during an active call. An identifier associated with the femto cell is then ascertained and reported.

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.

Techniques are described herein for updating proximity information associated with a femtocell in a wireless communication system. An example of a method described herein includes identifying a location within a wireless communication network, associating the location with a femtocell for which proximity information relating to position of the femtocell is maintained, performing at least one search for the femtocell, and updating the proximity information maintained for the femtocell based on results of the at least one search. Another example of a method described herein includes obtaining a report of proximity information relating to a femtocell, identifying one or more network devices for which the proximity information is relevant, and communicating proximity information update signaling to the one or more network devices.

Methods and apparatuses are provided that facilitate providing access point measurements to restricted access points. Restricted access points can lessen restrictions to allow devices to register with the restricted access point for providing measurements thereto. Additionally or alternatively, access point measurements can be provided to a minimization of drive tests (MDT) server for providing to the restricted access points. Thus, restricted access points can obtain the access point measurements for performing enhanced interference management or other functionality based at least in part on the measurements.
摘要:
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.

摘要:
Access terminals are provisioned to conduct intra-frequency, inter-frequency, and inter-RAT measurements and report physical layer identifiers of detected cells. The provisioning may involve cycling through all or a portion of a defined superset of physical layer identifier one subset at a time. In addition, the physical layer identifiers may be prioritized to improve the search procedure. Measurement report messages (including physical layer identifiers of the detected cells) are received at an access point as a result of the provisioning. A neighbor cell list for the femtocell is maintained based on the received measurement report messages and, optionally, other information. This other information may related to, for example, one or more of: physical layer identifier information received from access terminals that register with the access point, physical layer identifier information received via network listen operations, information regarding co-located cells, or physical layer identifier information received from a network entity.
