Abstract
(EN)
According to one embodiment, a communication terminal is described comprising a communication subsystem configured to send a first connection request to a first mobile radio communication core network, upon reception of a redirection instruction from the first mobile radio communication core network to a second mobile radio communication core network, try to connect to the second mobile radio communication core network and upon unsuccessful connection to the second mobile radio communication core network, send a second connection request to the first mobile radio communication core network indicating that the communication terminal has already been redirected to the second mobile radio communication core network.
