METHOD AND SYSTEM FOR SETTING UP A MULTICAST OR BROADCAST TRANSMISSION

摘要

The present invention relates to a method and system for setting up a broadcast or multicast transmission to a plurality of terminal devices (10) via a first switching node (40) and a second switching node (30) of a data network, wherein an information indicating the number of connections required between the second switching node (30) and the plurality of terminals (10) is provided to the first switching node (40), so that the first switching node (40) may determine based on the provided information a number of connections to be set up between the first switching node (40) and the second switching node (30). Thereby, the number of connections between the first and second switching nodes can be equalized so as to re-duce signal duplication and parameter adaptation requirements at said second switching node (30).
