Abstract
A packet radio network comprising a gateway support node, a serving support node and a radio network controller provides a facility for communicating internet packets with mobile user equipment. The gateway support node provides a packet data protocol context for controlling communication of internet packets between the packet radio network and mobile user equipment via a packet communications bearer. The serving support node connected to the gateway support node controls communications between the gateway support node and mobile user equipment forming the packet communications bearer. The radio network part provides a radio access bearer for communicating internet packets via a radio access interface with mobile user equipment. In response to a request message, the serving support node with the gateway support node establishes a common packet data protocol context with a packet communications bearer to communicate packets. The common packet communications bearer is shared with another communications session and formed by gateway support node and serving support node using a common tunnelling protocol bearer.
