PACKET RADIO COMMUNICATIONS SYSTEM

摘要

A packet radio communications system communicates internet packets to and/or from mobile user equipment. The system comprises a core network comprising a plurality of packet data networks, each including network communications elements operable to communicate internet packets using an internet protocol transport plane, and a common gateway support node. The gateway support node is operable to route the internet packets via communications bearers established through the packet data networks using the network communications elements. The system includes a plurality of radio access networks connected by the internet protocol transport plane to the core network components of the packet data networks for communicating the internet protocol packets to and/or from the mobile user equipment. Each of the radio access networks is operable to provide radio access bearers for communicating the internet packets to and/or from the mobile user equipment.

1. A packet radio communications system for communicating internet packets to and/or from one or more mobile user equipment, the system comprising
a core network comprising a plurality of packet data networks, each including network communications elements operable to communicate internet packets using an internet protocol transport plane, and a common gateway support node, the gateway support node being operable to route the internet packets to and from the mobile user equipment via one or more packet data communication bearers established through the packet data networks using the network communications elements, a plurality of radio access networks connected by the internet protocol transport plane to the network communications elements of the packet data networks for communicating the internet protocol packets to and/or from the mobile user equipment, each of the radio access networks being operable to provide radio access bearers for communicating the internet packets to and/or from the mobile user equipment, a packet service control subsystem function comprising an access network part and a non-access network part, the access network part being arranged to control a selection of the radio access networks for communicating the internet packets via the radio access bearers and the non-access network part being arranged to control the communication of the internet packets via the communications bearers using the network communications elements of the packet data networks by activating a packet data communication bearer suitable for supporting a communication session corresponding to the communication of the internet packets to and/or from the mobile user equipment, wherein at least one of the plurality of packet data networks is arranged to operate in accordance with a different telecommunications standard than the other packet data networks and wherein the packet service control subsystem function is operable to provide different qualities of service (QoS) implementations in establishing the packet data communication bearers which are then used to forward the internet packets according to the quality of service (QoS) as requested in one or more headers of the internet packets.
