At least one peer in the peer-to-peer network has a call center function added to it, and a check is then carried out by way of a search algorithm to determine whether a called subscriber is or is not registered in the peer-to-peer network. If the called subscriber is registered, an IP address is first of all determined for that subscriber, and a check is then carried out to determine whether the call center service has been activated for this subscriber. An incoming call is then diverted to a peer with a call center function, and is not passed on to the called subscriber until contact is made with the peer with the call center function. Otherwise, if the subscriber is not registered in the peer-to-peer network, further entries for the called subscriber are first of all checked in the peer-to-peer network. If there is an entry for an active call center service, an address of a peer with a call center function is sought, and the incoming call is then forwarded directly to that peer with the call center function. | 01-14-2010 |

20090016213 | METHOD FOR EFFICIENTLY TREATING DISTURBANCES IN THE PACKET-BASED TRANSMISSION OF TRAFFIC - The present disclosure relates to methods for efficiently treating disturbances in the packet-based transmission of traffic by means of a routing protocol and routing entities. According to an exemplary embodiment, a message signaling the non-availability of a neighboring routing entity is inspected. Once the message signaling the non-availability of a neighboring routing entity is received, a test message for verifying the information is sent. If the non-availability is confirmed upon inspection, the system deduces that there is a failure of the connection to the neighboring routing entity. The routing entity then occasions a change in routing in order to circumvent the failed connection. This configuration reduces the operations required for fault recovery in the network and protects the system from false error messages generated to disturb the network. | 01-15-2009 |

20080225833 | Apparatus For Guaranteeing the Availability of Subscribers in Communication Networks Over Network Boundaries - According to prior art, for example, when danger or environmental catastrophe are imminent, the population is warned by information guided via the communication network. This type of warning is however limited when the communication network consists of a plurality of sub-networks and the (warning) information must thus be transmitted over network boundaries to the subscriber The invention solves this problem in that a warning profile is associated with each route/transit switching centre trunk group. The association is carried out during the establishment of the route/transit switching centre trunk group, and is updated as required as changes of the network configuration. Each network transition implicitly thus has one such warning profile. | 09-18-2008 |

20080198741 | Method for Providing Alternative Paths as a Rapdid Reaction to the Failure of a Link Between Two Routing Domains - The present disclosure relates to a method for providing substitute routes in rapid response to the failure of a link between two routing domains in a packet-oriented network. After the failure of a link has been identified, substitute routes are provided for routes which have been interrupted by said failure by locally selecting alternative routes and propagating messages along the substitute routes. In order to provide substitute routes, an inter-domain router checks whether the router contains a substitute route. If there is no substitute route, a request message is transmitted to at least one adjacent inter-domain router and the transmission of at least one substitute route is thus requested. If there is a substitute route in the adjacent inter-domain router, the inter-domain router making the enquiries is informed of this in a response message. The present disclosure thus results in the improved provision of substitute routes in response to disruptions in inter-domain routing. | 08-21-2008 |
