Abstract: A mobile network component comprises a mobile management entity, MME, a software defined network controller, SDNC. The SDNC is configured to link to MME so as to establish directly Ethernet, MPLS or GRE based internet protocol with mobile QoS priorities mapped into Ethernet, MPLS or GRE transport priorities, IP, communications between evolved node b, eNB, SDN switch, and internet.

Abstract: A method and an arrangement maintain end-to-end synchronization on a telecommunications connection transmitting data in frames substantially in real time and using synchronized end-to-end encryption, wherein at least a part of the telecommunications connection is a packet-switched connection, in which case the reproduction delay of the data to be transmitted can be increased by adding one or more extra frames to the frame string being transmitted, wherein the arrangement defines, based on the number of received frames, an initialization vector value corresponding to a frame received at the receiving end of the telecommunications connection and used in decrypting the frame, adjusts the reproduction delay to mark the frame to be added to increase the reproduction delay as an extra frame, and defines the initialization vector value to count only the frames not marked as extra frames in the number of received frames.

Abstract: A method and an arrangement for maintaining end-to-end synchronization on a telecommunications connection transmitting data in frames substantially in real time and using synchronized end-to-end encryption, wherein at least a part of the telecommunications connection is a packet-switched connection (PDN), in which case the reproduction delay of the data to be transmitted can be increased by adding one or more extra frames (72) to the frame string (75) being transmitted, wherein the arrangement comprises means (MS, TE) for defining on the basis of the number of received frames an initialization vector value corresponding to a frame received at the receiving end of the telecommunications connection and used in decrypting the frame, and means (GW, TE) for adjusting the reproduction delay that are arranged to mark the frame to be added to increase the reproduction delay as an extra frame, and the means (MS, TE) for defining the initialization vector value are arranged to count only the frames not marked as extra

Abstract: The invention relates to a method for warming up a spare process in parallel with an active process in a replicated real-time switching system, in particular in a telephone exchange. The switching system comprises an active control unit (WP) having, permanently or when necessary, a replicating hot-standby spare unit (SP) connected to a common internal message bus, so that the spare unit performs the same processes as the active control unit in parallel. In accordance with the invention, the operation of the active process (.sigma..sup.WO) to be replicated is temporarily frozen in the active control unit (WP) when the process has no tasks to be performed, the other processes of the active control unit simultaneously being kept in operation. After this a spare process (.sigma..sup.SP) is created to the spare unit (SP), and the state data (.sigma..sup.WO) of the active process is loaded into the spare process. Provided that no new tasks have come in during this time to the active process (.sigma..sup.

Abstract: A system architecture offering service includes a Connection Management, a Service Management, and a Communication Session Management. A special adaptation software forms a description of the logical configuration of the communication between parties of the service, and a description of the status of the connection organs, which describes the physical connection between the subscribers or subscriber and a legacy exchange. In response to a system service request by a telecommunication network the Service Management gives a description of the desired communication status which corresponds to the requested service of the communication status, and the description of the state of the connection organs. The Communication Session Management determines what kind of communication status corresponds to the given connection status, utilizing the description of the status of the connection organs that has been transmitted to it.
