Abstract:
1. A telecommunications system for providing a facility for mobile communications to a mobile node, the system comprising: a packet radio network comprising a core network and a radio network, the core network being arranged to communicate internet packets to and from the radio network in accordance with a location of the mobile node within the packet radio network, and the radio network being arranged to communicate the internet packets received via the core network to and from the mobile node from and sent to a radio access interface, the core network and the radio network being arranged to communicate the internet packets in accordance with a current configuration of routing and communications resources of at least one of the core network and the radio network, established in accordance with the location of the mobile node, wherein the mobile node is arranged to generate a packet data connection activation request in accordance with a packet connection procedure for establishing a communications bearer for communicating the internet packets across the mobile radio network, a service level identifier being inserted in a field of the packet data connection activation request, the service level identifier representing a priority to be afforded to communicating internet packets to or from the mobile node with respect to the internet packets received from other mobile nodes, and to communicate the packet data connection request to the core network of the packet radio network, wherein the core network is arranged to establish a communications bearer to and from the mobile node via the core network and the radio network in accordance with the packet data connection request, and to alter the current configuration of routing and communications resources of at least one of the core network and the radio network following a change of location of the mobile node with a relative priority determined in accordance with the service level identifier, wherein the routing configuration and communications resources include providing the core network with a routing area, to which internet packets are routed to and received from so that the internet packets can be communicated to and received from the mobile node, and in response to a routing area update request received from the mobile node, the core network is arranged to process the routing area update request in accordance with the requested priority represented by the service level identifier, wherein the core network comprises at least one serving packet radio system support node and a packet radio system gateway support node, and the routing area update request received from the mobile node includes an intra serving packet radio system support node routing area update.
