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 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： A cell reselection parameter is transmitted on one carrier frequency for a defined period of time to cause access terminals operating on that carrier frequency to more aggressively search for access points on at least one other carrier frequency. For example, a femto cell operating on one carrier frequency may transmit a broadcast channel including a cell reselection parameter such as Sintersearch on another carrier frequency that is used by a macro cell. Here, the value of the cell reselection parameter (e.g., Sintersearch) is chosen so that the access terminals will more aggressively conduct inter-frequency searches. In addition, the cell reselection parameter is transmitted for a period of time that ensures that a nearby access terminal will receive the parameter during its wakeup interval.
