In a cellular network, femto base stations may be deployed to improve indoor coverage that cannot be accommodated by the macro base stations. However, to switch from the macro-tier to the femto-tier, a user equipment may be required to scan the whole femto radio spectrum, which is an expensive operation. We propose a cache scheme that may significantly speed up the macro-tier to femto-tier switching.
