UE-SUBSTITUTE-UNIT OF A COMMUNICATION NETWORK

Techniques for communication in a communication system, comprising the following steps* providing domain units, wherein the domain units provide a functionality of the network for communication by means of network functions; wherein at least one of the domain units is represented by a UE having at least one UE-network-function, wherein the UE communicates with the network by means of a radio link;* providing a database within the network, wherein the domain units communicate via a communication link with the database, and wherein the domain units each retrieve data from the database and/or write data output obtained by their network functions into the database to execute their network functionality;* providing a UE-substitute-unit within the communication system having at least one of said UE-network-functions, said UE-substitute-unit at least temporarily substituting for said UE, which is temporarily not connected because of network interrupts, wherein the UE-substitute-unit executes the at least UE-network-functions and retrieves data from said database and/or writes data output obtained by the UE-network-function into said database.
