A packet radio network provides a facility for communicating internet packets to and/or from a mobile user equipment. The packet radio network comprises a gateway support node, a serving support node and a radio network controller. In response to a packet data protocol activation request message requesting a common packet data protocol context, the serving support node is operable in combination with the gateway support node to establish a common packet data protocol context in association with a common packet communications bearer. The common packet data protocol context is established to communicate internet protocol packets via the common packet communications bearer. The common packet communications bearer is shared with at least one other communications session and is formed by the gateway support node and the serving support node using a common tunnelling protocol bearer. Therefore a packet radio network is provided which can provide a common communications bearer which can be shared between different communications sessions. As a result high-speed broadband communications, such as HSDPA can be supported efficiently, because more than one communications session shares common communications resources. |
