Message generating device for communication system, has number of identifications that are assigned to communication terminal, which is registered in communication network by using identifications

摘要

The device has a number of identifications that are assigned to a communication terminal. The communication terminal is registered in the communication network by using the identifications. Identifications are combined to an identification-group. A communication terminal is registered in the communication network, under identifications in the identification-group, where a message (101) is provided as an information message, by which the communication terminal is signalized. An independent claim is also included for a method for operating a communication system.
