Abstract
A packet radio data network, comprising at least one gateway node (GGSN), at least one node in service (SGSN), connected to the gateway node, a plurality of radio access nodes (RAN), connected to the node in service (SGSN), such that the packet radio network transports packet data from an external packet data network, comprising an Internet Service Provider (ISP), to mobile stations (MS) attached wirelessly to radio access nodes (RAN), such that the gateway node comprises a functional routing capability for tunnel transmission of IP data streams to a mobile station, through the hitch point given from the mobile station to a radio access node (RAN), so that the node in service is involved in PDP context activation procedures that allow a given mobile station to carry out a switched communication in packets with l The external network of packet data, and allowing the loading of such communication, characterized in that at least the gateway node, subsequently to the activation of the multipoint or multi-point PDP context, establishes at least a first tunnel of multiple broadcast (GTPT1 - GTPT4, GTPT10 - GTPT35) between the gateway node and at least one node in service, so that the multiple broadcast tunnel that carries the IP data streams belongs to at least two mobile stations belonging to a common multiple broadcast group, the node in service comprises mobility and security management functions for mobile stations, and because the first multiple broadcast tunnel comprises combined IP data streams belonging to a plurality of multiple broadcast groups .
