TELECOMMUNICATIONS SYSTEM AND METHOD

摘要

A telecommunications system is operable to provide a facility for mobile communications to a mobile node. The telecommunications system includes a packet radio network comprising a core network and a radio network. The core network and the radio network are 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. The mobile node is operable in accordance with a packet connection procedure for establishing a communications bearer for communicating the internet packets across the mobile radio network, to generate a packet data connection activation request. The packet data connection activation request is adapted to include a 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. The core network is operable 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 adapt 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. Through the inclusion of the service level identifier in the packet data connection request, the telecommunications system can give a relative priority to mobile nodes requiring a higher priority data transmission thereby reducing delays or interruptions in the transmission of data.
