Described embodiments provide a method and apparatus for redirecting user equipment from a current serving cell of a first network to a corresponding target cell of a second network in a heterogeneous overlay network environment. A current serving base station of the first network may receive signal quality measurements from user equipment coupled to the current serving cell of the first network. Based on the received signal quality measurements, the current serving base station may determine whether signal quality of the user equipment is lower than predetermined reference quality based on at least one of the received signal quality measurements. When the signal quality of the user equipment is lower than the predetermined reference quality, the current serving base station may redirect the user equipment from the current serving cell of the first network to the corresponding target cell of the second network.
