METHOD AND NETWORK ELEMENT FOR FORWARDING MULTICAST MESSAGES |
摘要 |
The present invention relates to a method and network element for forwarding a multicast message received from an external packet data network (PDN) to subscribers (MS) of a packet radio network, wherein a subscriber-specific information defining multicast messages to be received by the subscribers is stored in a network element (GGSN) of the packet radio network. Based on this subscriber-specific information, a point to point connection is established between the multicast content provider of the multicast message and a subscriber having joined the corresponding multicast group. The subscriber may request a list of available multicast groups from the network element and may inform the network element of the multicast messages he wants to listen to by using a point to point context activation. Thus, the network element which may be a gateway GPRS support node plays an arbitrator role for multicast messages. Thereby, only minor changes of standard network elements are required.
