Abstract: A communication network that includes a first sub-network (101) and a second sub-network (103) each supporting separate multicast domains. A first interface network element (111) includes a multicast receiver (201) for receiving multicast data packets. A transmit translation processor (203) generates unicast data packets by replacing a multicast address of the multicast data packets by a unicast address. A unicast transmitter (207) forwards the unicast data packets to a second interface network element (113) over a unicast communication link (119). The second interface network element (113) comprises a unicast receiver and a receive translation processor (303) which generates multicast data packets by replacing a unicast address of the unicast data packets by a multicast address. The multicast data packets are then fed to the second sub-network (103).

Abstract: A method (200) for asynchronous live video transmission over a communication network which comprises the receipt of individual requests from a video client for the transmission of a single frame which has not previously been transmitted. Requests specify the encoding parameters (I-frame periodicity, quantisation and resolution) determined by the video client. Frames of live video are captured (204) and encoded (206) according to the parameters specified in the request. The parameters may be changed in response to available bandwidth. Retransmission of lost or corrupted frames may be requested with changed parameters. A rolling buffer may be used to store frames after encoding.

Location data may be sent to the mobile station, or another mobile station can request the location of the mobile station. An emergency message may be conveyed to a mobile station or a location query may be sent.

Abstract: A user terminal (109) for use in a mobile communication system (100) which includes a processor (102, 311, 312) operable to monitor data intended to be sent via a communication resource (PDCH) of the system to another terminal (119) and to detect whether the intended data transmission conforms with one or more pre-defined rules defining well behaved data transmission and, if the violation of one or more of the rules is detected, to initiate a procedure to determine if the data transmission is allowed to proceed. The procedure may include producing an alert signal for sending to a processor (112) of an infrastructure (101) of the system. A processor (112) for use in an infrastructure (101) of the mobile communication system (100) is operable to receive an alert signal from the user terminal (109), to determine whether or not the intended data transmission is allowed to proceed and to issue a response signal for sending back to the user terminal indicating a result of the determination.

Abstract: Disclosed is a method for using mobile communication systems for the control of the movement of mobile objects. The system comprises a control station which receives from mobile stations location information relating to a current location of the stations, the mobile stations being carried by the mobile objects. The control station detects from the location information received that one of the mobile stations is approaching the current location of another of the mobile stations and issues an alert signal to either or both of the mobile stations to indicate an alert condition related to the detected approach. The processor of the central control may calculate a probability that a collision will occur and issues a warning then the probability reaches a preset threshold and a second more urgent warning when a second higher threshold is past. The warning may be issued based on the distance between the mobile stations. The mobile station may send a time index and speed data to the control station. The mobile objects may be land vehicles eg trains, waterborne eg ships or airborne.

Abstract: A data communication system (100), which is capable of supporting multicast data delivery, comprises a router (110) for routeing at least one data packet between two or more networks, the data communication system (100). The router (110) comprises a processor (210) to receive and decode at least one multicast data packet and translate a multicast address of the decoded at least one multicast data packet into one or more unicast addresses. In this manner, the provision of a processor to translate a multicast address of the decoded at least one multicast data packet into one or more unicast addresses allows a simple unicast-capable host to receive and deal with multicast addressed packets in contrast to requiring all hosts being multicast-capable. Furthermore, it allows reuse of legacy equipment (i.e. unicast-only hosts can still be used in a multicast environment).

The control station may automatically issue the alert signal based on a prediction of a probable collision. The first mobile station may be carried on a train or ship or other transport vehicle and the second mobile station may be a radio of a user who is located in the intended path of the train or ship or other vehicle. Also described is a control station, a mobile station and a method for use in the system.
