There is known a telecommunication terminal with a miniature display for received, visually perceptible information, such as, for example, fax messages. In addition, a device is known for projecting computer images or TV images, the device comprising a so-called DMD chip (Digital Mirror Device). It is proposed to improve the aforedescribed telecommunication terminal (MS) by providing the terminal with projection means (DMD, FL) which can basically only be used for the device described above. In addition, the device described above is improved by being provided with an interface circuit for connection to a telecommunication terminal. Accordingly, the conventional means known in the field of computer technology and TV technology for projecting images are now used in or for a telecommunication terminal, especially in a mobile radio telephone (MS). With the received image data, images can be projected directly onto a projection screen, for example, onto a wall. Several people can view the images simultaneously. An output device, such as, for example, a printer for fax messages, is not required.

To facilitate routing changes, a telecommunications network (10, 10′, 10′″) includes a centralized network routing database (28) queried by each ingress switch upon receipt of a call by a calling subscriber (12). In response to the query, the network routing database returns to the querying switch the identity on the next (downstream) switch in the routing path. The querying switch then translates the switch identity to establish the link to that next switch. Because each querying switch makes the necessary translation of the next switch identity to make the link to the next switch, the centralized network database need not concern itself with the particular characteristics of the switch. To make global routing changes, only the network routing database need be updated, not each individual switch.

A method communicating data between a base station and a terminal device in a wireless telecommunications system, for example an LTE-based system. The wireless communication system uses plural frequency sub-carriers spanning a system frequency band. Physical-layer control information for the terminal device is transmitted from the base station using sub-carriers selected from across the system frequency band, for example to provide frequency diversity. However, higher-layer data for the terminal device is transmitted using only sub-carriers selected from within a restricted frequency band which is smaller than and within the system frequency band. The terminal device is aware of the restricted frequency band, and as such need only buffer and process data within this restricted frequency band during periods where higher-layer data is being transmitted. The terminal device buffers and processes the full system frequency band during periods when physical-layer control information is being transmitted.

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.

The present invention relates generally to telecommunications, and more specifically, to an improved operating system and apparatus for telecommunications networks. Currently, the majority of telecommunication services are provided over the Public Switched Telephone Network and Internet. Existing telephony systems suffer from a number of problems including system complexity, limited access and implementation of services on fixed hardware, which results in long time to bring new products to market. Internet applications cannot guarantee quality of service in the transmission. These systems are therefore inflexible and inefficient which limits their ability to carry new services. The invention provides a distributed and real-time operating system for use over varied telecommunications networks. As well, methods of implementing synchronized execution, fault tolerance and loading management over this network, are also described. The application of this operating system to existing networks allows new services to be provided.

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.
