| 20090310559 | Seamless Handover of a Mobile Station from a Macro Base Station to a Privately Accessible Femto Base Station - In an embodiment, a method is provided that includes receiving a handover request for a mobile station to be handed over to a macro base station. Identification information for the mobile station is received. The identification of the mobile station is compared with stored association information that includes identification information of a femto base station, and identification information for a particular mobile station. The method further includes identifying that the mobile station identification information matches the identification information for an associated mobile station using the stored association information. The information regarding the associated femto base station is transmitted to the associated mobile station. | 12-17-2009 |
| 20090310568 | Seamless Handover and Load Balance Between Macro Base Stations and Publicly Accessible Femto Base Stations - The teachings of the present disclosure relate to seamless handover between macro base stations and publicly accessible femto base stations that includes scheduling a null period in a femto base station's communications activity. The method also includes monitoring mobile station activity during the null period at the femto base station. A candidate mobile station is identified based on the monitoring. An identifier of the candidate mobile station is transmitted from the femto base station to a macro base station. The identifier may be used to initiate handover of service of the candidate mobile station from the macro base station to the femto base station. | 12-17-2009 |
| 20090312019 | Mobile Station Assisted Seamless Handover to a Femto Base Station - According to an embodiment, a method is provided. The method includes identifying a femto base station of a wireless network as the home femto base station for a mobile station served by the wireless network. The connection parameters for the home femto base station may be stored at the mobile station. A home macro base station may be identified and associated with the home femto base station. Identification information for the home macro base station may be stored at the mobile station. Association information of the home femto base station with the home macro base station may be stored at the mobile station. | 12-17-2009 |
| 20090312024 | Seamless Handover Between Macro Base Stations and Publicly Accessible Femto Base Stations - The teachings of the present disclosure relate to seamless handover between macro base stations and publicly accessible femto base stations that includes determining the location of each of a plurality of femto base stations in the coverage area of a macro base station. A plurality of groups according to the locations of the particular femto base stations are created. The groups are a subset of the plurality of femto base stations. Finally, identification information for one or more of the groups of femto base stations is transmitted to a mobile station in the coverage area of the macro base station. | 12-17-2009 |
