Abstract: In one aspect, a method in a packet-switched network for accessing a first subscriber is provided. A control server receives a message intended for the first subscriber of the packet-switched network. The control server inquires a topology database for information of how to reach the first subscriber according to the topology of the packet-switched network. A response having a topological path description is received by the control server. The message is transmitted to the first subscriber in accordance with the received topological path. Whereby, the first subscriber is assessable via a plurality of control servers in the packet-switched network.

Abstract: Short messages (SMS) or short messages containing images (MMS) are sent in a reliable, cost-optimized, and time-optimized manner to an IP-compatible terminal, e.g. a set-top box that is connected to a telecommunication network by expanding the functions of the distribution center for SMS/MMS messages and a registration entity for IP connections.

Abstract: In one aspect a system for transferring messages from a communication unit such as a phone, a cellular or mobile phone, a personal computer, a digital camera, or a digital video camera to other compatible systems such as digital set-top boxes, multimedia terminals, digital TV receivers or digital TVs is provided The system communication unit and a television device, by utilizing a base station in a wireless communications network, a communications provider connecting to the base station, a television network operator operating a television distribution network, and a television device.

Abstract: Disaster recovery of an IP network having a working area, which includes at least a switch for routing traffic through the IP network, is provided. A first mode (402) is provided wherein the working area is active and routes traffic through the IP network, a backup area that has a functionality to route the traffic through the IP network, the backup area is maintained in standby and IP addresses relating to the traffic are stored in a storage area. A second mode (406) is provided wherein, when the working area is inoperable due to disaster, the backup is activated such that the backup area routes the traffic through the IP network with the IP addresses stored in the storage area.
