Abstract
A mobile station is configured to transmit a first location registration related signal addressed to a first exchange to a radio network controller, so as to perform location registration to both the first exchange and a second exchange, when operating in first network operation mode. The mobile station includes a controller configured to transmit a second location registration related signal addressed to the second exchange to the radio network controller, so as to perform the location registration to the second exchange without passing thorough the first exchange, when the mobile station operates in the first network operation mode and when the mobile station receives an access restriction signal for the first exchange from the radio network controller.
