METHDO, BASE STATION AND MOBILE TERMINAL FOR PROVIDING CS FALLBACK SERVICE FOR LOAD BALANCING

摘要

Described embodiments provide a method of a circuit switched (CS) fallback procedure at a first network providing only a packet switched (PS) service. A CS fallback procedure may be initiated upon a receipt of a call associated with a CS service. One of carriers assigned to a second network that provides a circuit switched (CS) service may be selected. Then, a second network cell mapped to a serving cell of the first network and using the selected carrier may be selected as a target cell. The user equipment may be handed over o to the selected second network cell in order to provide a requested CS service.
