A circuit service tunneling system is provided. The circuit service tunneling system has a first and a second mobile service network, and a user equipment. The first mobile service network provides packet-switched domain services and the second mobile service network provides circuit-switched domain services. An interworking system in the second mobile service network interconnects the first mobile service network with the second mobile service network, by connecting to a mobility management entity in the first mobile service network, to enable the first mobile service network to provide the circuit-switched domain service to the user equipment via the second mobile service network.
