The ranking criteria of a serving or neighbor cell, or a reselection timer in a wireless transmit/receive unit (WTRU), is adjusted based on how a serving cell signal measurement, (e.g., signal strength, signal quality), compares to a plurality of thresholds over a time interval. In another method, cell ranking criteria is adjusted based on a hysteresis value and a scaling factor when a maximum number of reselections is exceeded and a high mobility factor is detected. Furthermore, a method of reporting cell signal measurements is disclosed, whereby a time-to-trigger time (TTT) interval is started when the neighbor cell signal measurement rises above a reporting range threshold.

| 20160192248 | METHOD AND APPARATUS FOR FACILITATING A BEACON-ASSISTED HANDOVER TO A HOME NODE-B FOR USERS ON AN ACTIVE CALL - 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. | 06-30-2016 |
