Abstract
The invention relates to a method, a broadcast management centre, a router, a host and a system for performing broadcast in a point-to-point oriented packet-switched telecommunication network. The basic idea is to use multicast for parts of the transmission within said telecommunication network. The multicast technique is used to send broadcast data to a geographical broadcast group to which a network node belongs. The network nodes are configured to a certain geographical broadcast group by the broadcast management centre.

20. A method for broadcasting messages in a point-to-point oriented packet-switched telecommunication network, said network having a set of network nodes comprising a first router and at least one host serving at least one user, wherein the first router communicates with a broadcast capable server that provides broadcast data, said method comprising the steps of:
-
configuring the network nodes by a broadcast management centre for broadcast provisioning within a geographical broadcast group, said broadcast management centre ordering the network nodes to register to the geographical broadcast group;
sending, from said broadcast capable server, the broadcast data to the first router;
using multicast techniques on the transport layer to route the broadcast data from the first router to the at least one host belonging to the geographical broadcast group; and
using a broadcast technique to send the broadcast data from said host to the at least one user. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33)

34. A broadcast management centre for broadcast and/or multicast management in a point-to-point oriented packet-switched telecommunication network having a set of network nodes, wherein the set comprises a first router and at least one host serving at least one user and the first router communicates with a broadcast capable server providing broadcast data, said broadcast management centre comprising:
-
a configuration unit for configuration of the network nodes to a geographical broadcast group, wherein the network nodes are registered to the geographical broadcast group;
a communication unit for communicating with the network nodes; and
a receiving unit for receiving information on which basis the geographical broadcast group is determined.

35. A router adapted to perform multicast in a point-to-point oriented packet-switched telecommunication network having a set of network nodes, wherein the set comprises at least one router and at least one host serving at least one user and the first router communicates with a broadcast capable server providing broadcast data, said router comprising:
-
a configuration unit for configuring the network nodes in order to provide a geographical broadcast group, wherein the network nodes are registered to the geographical broadcast group;
a receiving unit for receiving data;
means for providing multicast techniques on the transport layer; and
a sending unit for sending the multicast data towards the host belonging to the geographical broadcast group. - View Dependent Claims (36)

37. A host adapted to perform broadcast in a point-to-point oriented packet-switched telecommunication network, wherein the host is connected on one side to at least one router and on the other side to at least one user, and wherein the host is configured by the broadcast management centre, said host comprising:
-
a receiving unit for receiving multicast data sent by means of a multicast technique on the transport layer from the router;
an association unit for association of the received multicast data to the broadcast data sent to the user;
means for providing broadcast technique to the user; and
sending unit for sending the data to the user.
