摘要： A telecommunications system is arranged to provide a mobile communications session to a mobile node using an internet protocol. The telecommunications system comprises a home packet data network which includes a home agent of the mobile node and a visited packet data network. One of the home packet data network or the visited packet data network includes a packet data gateway for controlling the communication of the internet packets to and from the home packet data network from and to the visited packet data network. The mobile node is arranged to communicate a correspondent node binding update internet packet to the correspondent node via the packet date gateway, when the mobile node changes affiliation from the home packet data network to the visited packet data network. The correspondent node binding update internet packet provides a care of address of the mobile node within the visited packet data network and a home address of the mobile node. The packet data network is arranged to store the home address of the mobile node in association with the care of address of the mobile node, to adapt the correspondent node binding update internet packet by replacing the care of address in the received correspondent binding update packet with the address of the packet data gateway, and to communicate the adapted correspondent binding update packet to the correspondent node. The correspondent node therefore receives a correspondent binding update with the packet data gateway as the care of address. Thus, when the correspondent node communicates with the mobile node using the care of address of the packet data gateway, the packet data gateway can adapt the received internet packets, replacing the packet data gateway's address as the destination address with the care of address of the mobile node. Therefore, although a route optimisation process has taken place the internet packets are still routed via the packet data gateway .

摘要： A telecommunications system provides an internet protocol multimedia communications session to a mobile user equipment. The system comprises an internet protocol multimedia subsystem including a call state control function operable to control the multimedia communications sessions, and a home subscriber server operable to provide information associated with the mobile user equipment for providing the communications session. A packet radio network is operable to provide a mobile communications facility to the mobile user equipment to support the multimedia communications session. The call state control function is operable in response to a request message from the mobile user equipment for the communications session to be established, to generate an authorisation token for the mobile user equipment in accordance with subscriber information representing a service to which the mobile user equipment has subscribed. The request from the mobile user equipment identifies that the communications session requested is for one of a group communications session sharing a communications resource, or a single communications session for which a communications resource is dedicated to the mobile user equipment. The authorisation token generated by the serving call state control function for communication to the mobile user equipment provides an indication that the mobile user equipment can use correspondingly one of a common communications bearer or a dedicated communications bearer via which the communications session can be supported. As such a plurality of mobile user equipment can request and receive a group multi-media communications session authorised through a token based authorisation procedure. The packet radio network can then allocate a group multi-media communications session, which shares a common packet communications bearer.

摘要： A telecommunications system for communicating internet packets between a mobile communications user equipment forming a correspondent node and a mobile node via an external packet data telecommunications network. The system comprises a packet radio network providing a plurality of packet data bearers for communicating internet packets with nodes attached to the packet radio network. Each of the bearers is defined with respect to a source address of the internet packets, the packet radio network including a gateway support node operable to provide an interface between the external network and, the packet radio network. The gateway support node (GGSN) is operable to detect (56) whether an internet packet is for providing a binding update to the correspondent node of a first source address of the mobile node to a care-of-address of the mobile node. If the internet packet is a binding update, the gateway support node allows (514) egress of internet packets sent from the correspondent node having the care-of-address of the mobile node as the destination address to the external network. By obtaining the care-of-address of the mobile node from the binding update and allowing egress of packets from the correspondent node having this care-of­-address as the destination address in internet packet headers, a measure of security is provided, which can prevent or at least hinder theft of service. Theft of service may occur if an unscrupulous user uses an unauthorised destination address for IP data packets sent from the mobile user equipment acting as correspondent node and having a legitimate address in the hop-by-hop extension field and an unauthorised address in the destination field address.

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.
