Localisation of preturbations in communication connections

摘要

The method involves operating a mobile terminal device (3) in mobile radio networks, where the device uses a mobile radio subscriber-identification-module (SIM) card for an access to the network. A home location register (HLR) of the SIM card, is placed in a primary mobile radio network (1). The device is operated in a secondary mobile radio network (2). Primary devices (6,7) are connected to secondary devices (8,9) for communication. An availability request and a capacity request are sent from primary to secondary devices, which manage the abidance of the device. An independent claim is also included for network nodes of a mobile radio network.
