Abstract:
1. A user equipment connected to a first mobile service network providing packet-switched domain services, comprising: a first communications protocol module for communicating with the first mobile service network; a circuit switch tunneling control module for establishing a circuit service tunnel, via the first mobile service network, from the user equipment to an interworking node of a second mobile service network providing circuit-switched domain services, wherein the interworking node is connecting the second mobile service network to the first mobile service network; and a circuit switch tunneling data module for transmitting a circuit service tunneling message for the second mobile service network via the circuit service tunnel, wherein the circuit switch tunneling control module further receives a measurement request from the second mobile service network, performs a pilot measurement on the first mobile service network, and transmits a measurement result obtained from the pilot measurement to the second mobile service network.
