Abstract
A mobile terminal, which is registered to either a first mobile communication network or a second communication network, determines whether it is possible to register to the first mobile communication network on the basis of control information received from the second mobile communication network. Then, the mobile terminal attempts to register to the first mobile communication network a predetermined number of times in a case that it is determined that it is possible to register to the first mobile communication network.
