1. A method of load balancing for a second network in a wireless communication system, the method comprising:
the second network receiving a first cause or a packet-switched establishment cause included in a radio resource control (RRC) connection request message from a mobile device when the mobile device is moved from a first network to the second network; and the second network not redirecting the mobile device back to the first network when the second network receives the first cause and redirecting the mobile device back to the first network when the second network receives the packet-switched establishment cause; wherein the first network is an E-UTRAN (Evolved UMTS Terrestrial Radio Access Network) and the second network is a UTRAN (UMTS Terrestrial Radio Access Network); wherein the first cause is a circuit-switched (CS) establishment cause, an Inter-RAT cell changed order or a value designed for redirection.
