Embodiment Construction

[0043] Various aspects are now described with reference to the figures. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of one or more aspects. It may be evident, however, that these aspects may be practiced without these specific details.

[0044] As further described herein, various aspects related to generating a beacon at a femto node operable to initiate hand-in of a device from a macrocell base station are presented. Although described with respect to femto cells, it should be appreciated that the concepts of the present application may be utilized in conjunction with substantially any low power base station (eg, H(e)NB, pico or micro cell node, relay node, etc.). Additionally, while active mode hand-in is contemplated, this application may also utilize additional terms such as handover, and both terms are intended to broadly encompass substantially any hand-in or handover me...

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.

Description

[0001] Claiming priority under 35 U.S.C. §119 [0002] This patent application claims the benefit of U.S. Provisional Application No. 61 / 418,589, filed December 1, 2010, entitled "APPARATUS AND METHODS FOR HAND-IN TO A FEMTO NODE," and filed December 10, 2010, entitled Priority to U.S. Provisional Application No. 61 / 422,119 for "APPARATUS AND METHOD FOR PERFORMING HAND-IN TO A FEMTOCELL," both of which are assigned to the assignee of this application and are hereby incorporated by reference . technical field [0003] In general, the following description relates to wireless network communication, and specifically, the following description relates to hand-in of device communication between base stations. Background technique [0004] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, data, and so on. A typical wireless communication system may be a multiple-access system capable of supporting communication w...
