20110053599 | SYSTEM, APPARATUS, AND METHOD FOR HANDOVER PROCEDURE - A method for a handover procedure comprises detecting a status of a backhaul connection between an original femto base station and a backbone network, and sending a handover request message including a reason code and/or flag to at least one mobile station served by the original femto base station, then the at least one mobile station re-associates with at least one base station other than the original femto base station. | 03-03-2011 |

20130045745 | Method for Reducing the Handover Frequency by a Communication Device in Femtocell Networks - A method for reducing the handover frequency by a communication device in femtocell networks includes the steps: measuring the radio signal strength by a communication device and storing the information of the serving base station into a cache memory; checking whether the stored information in the cache memory is classified as “femtocell” or not; if so, deleting the macrocell's information from the measurement report by the communication device and transmitting this to the serving base station; when the radio link failure occurred, checking whether the stored information in the cache memory is classified as “femtocell” or not; if so, initiating a timer; detecting an available femtocell before the timer expires; transmitting a call reestablishment request message to the available femtocell for rebuilding the link. | 02-21-2013 |

20130045748 | METHOD FOR REDUCING THE HANDOVER FREQUENCY BY A FEMTO GATEWAY IN FEMTOCELL NETWORKS - A method for reducing the handover frequency by a femto gateway in femtocell networks includes the steps: receiving a measurement report from a communication device by an initial femtocell; transmitting a relocation required message to a femto gateway by the initial femtocell if the signal strength thereof is below a threshold; ignoring the relocation required message and enabling the timer by the femto gateway after receiving the relocation required message; determining whether the cell ID included in the call reestablishment request message is classified as “femtocell” or not by the femto gateway before the timer expires; if so, rebuilding the link to the femtocell in response to the cell ID by the femto gateway. | 02-21-2013 |
