Abstract: A method for the switchover of a mobile terminal device from a first radio network of a mobile radio system to a second radio network is described. The switchover is carried out on the basis of a CS fallback mechanism, and whereby, on the basis of the switchover, the mobile terminal device logs on to a base station of the second radio network in order to establish a connection. In conjunction with the log-on, the mobile terminal device transmits a notification pertaining to the CS fallback mechanism to the base station, and the base station registers the log-on of the terminal device as a function of the notification. Moreover, a base station and to a mobile terminal device for carrying out the method are also described herein.

Abstract: There is provided a method for a mobile communication device registering in second radio cell of a mobile communication network based on a deactivation of a first radio cell in which the mobile communication device was located. An exemplary method comprises determining a random time interval by the mobile communication device. An expiration of the random time interval is determined starting from a predetermined point in time. The exemplary method also comprises registering in the second radio cell, when the expiration of the random time interval has been determined.

Abstract: There is provided a method that relates to the setting up and/or maintaining of a connection between a machine-to-machine (M2M) device and a mobile communication network. In order to be able to adapt the connection management to the requirements of the M2M device, the M2M device may transmit an indication that it is an M2M device to the mobile communication network. At least one network node of the mobile communication network controls the setting up and/or the maintaining of the connection based on the indication. The network node may route a request for setting up the connection to a further network node based on the indication.
