摘要： Methods and apparatus that enable a wireless femtocell to operate in its designated frequency so as to minimize interference between the wireless femtocell and neighboring base stations (and other femtocells or nomadic cells). In one exemplary embodiment, the femtocell cell comprises a UMTS (Universal Mobile Telecommunications System) femtocell which has the ability to scan the air interface in a manner similar to that associated with a UE in order to identify unallocated resources within the wireless network, and subsequently request access for the unallocated resources. Business methods useful in combination with the aforementioned methods and apparatus are also disclosed.

摘要： A method and mobile communication device that reduce communication interruption time when a base station stops operating are described. The mobile communication device is wirelessly connected to a cell operated by a base station. The method includes determining a fallback cell, obtaining parameters to quickly establish a wireless connection to the fallback cell, determining that the base station is stopping operation, and using the parameters to quickly establish a wireless connection to the fallback cell. Also described are a base station and method for the base station to reduce communication interruption time. The method includes determining that the base station is stopping operation, switching to a backup power source if the base station is stopping operation due to loss of power, and transmitting a message to the mobile communication devices connected to the base station that they should switch to a fallback cell, since the base station is stopping operation.
