Abstract
When a mobile station (UE) is camping on a system of the LTE scheme, a function (EMM) is configured to transmit a service request signal including a “CSFB” to an MME; the NNE is configured to transmit setup information including a “CSFB” to an eNB in response to the service request signal transmitted by the function (EMM); the eNB is configured to transmit, to a function (AS), instruction information instructing to select a cell in a system of the WCDMA/GSM scheme in response to the setup information transmitted by the MME; the function (AS) is configured to select the cell in the system of the WCDMA/GSM scheme in accordance with the instruction information transmitted by the eNB; and the function (MM) is configured to set up circuit switched communications via the cell in the system of the WCDMA/GSM scheme selected by the function (AS).
