Abstract: A method for processing of network communication between a telecommunications network and at least one user equipment includes: subscription data, session data and/or call state data required to be available to at least a first virtual network function instance are transmitted, by a shared database functionality, to the first virtual network function instance; in case of at least a change being applied to the subscription data, session data and/or call state data, the changed subscription data, session data and/or call state data or an updated version of the subscription data, session data and/or call state data is transmitted, by the first virtual network function instance, to the shared database functionality; and in case of a failure of and/or a transfer of the functionality of the first virtual network function instance, a second virtual network function instance resumes the functionality of the first virtual network function instance.

Abstract: A network protection entity for protecting a communication network against fraud messages includes: a physical interface comprising a connection trunk associated to the physical interface for receiving a communication message comprising a message source address and a port number. The communication message is directed to a destination within the communication network; a storage for storing a table appropriate for indicating a dedicated source address and a dedicated port number for the physical interface and the associated connection trunk; and a processor configured to retrieve the dedicated source address and port number from the storage and to compare the message source address with the dedicated source address and the port number with the dedicated port number. The processor is configured to discard the communication message if either the message source address differs from the dedicated source address or the port number differs from the dedicated port number.

Abstract: International-roaming-relevant data are exchanged between two roaming partner networks as part of a new communication relationship. From the start of this communication relationship, a logbook is maintained at least on the data-processing system of the first communication network in which logbook changes are entered that relate to the content of the local database. Based on entries in the logbook, the data-processing system recognizes in completely automatic fashion that a synchronization of data is required and implements this action between the internal network operator database and the data-processing system of the second communication network.

Abstract: Method for comparing network data, particularly roaming data and/or routing data, between at least two databases (3, 4), wherein a first database (3) is connected to a first data processing system (2) and the first data processing system (2) is associated with a first communication network (1). A second database (4) is connected to a second data processing system (5) and the second data processing system (5) is associated with a second communication network (6). The first and the second data processing system (2, 5) are connected by a communication connection (7, 8, 9). In the first database (3), network data located in data records are stored and are provided for comparison to the second database (4).
