Abstract:
Embodiments provide an apparatus, a method and a computer program for scheduling a data transmission. The apparatus 10 is operable for scheduling data transmissions to a mobile transceiver in a mobile communication system. The apparatus 10 comprises means for determining 12 a delay between a transmission of a first data packet and a transmission of a next data packet to the mobile transceiver, the delay depending on an acknowledgement packet received from the mobile transceiver for the first data packet. The apparatus 10 further comprises means for scheduling 14 data transmissions to the mobile transceiver based on the delay.
Abstract:
A vehicle messaging transmission method, a vehicle messaging transmitter, a vehicle messaging reception method, a vehicle messaging receiver, an infrastructure node method, and infrastructure node and computer program products are disclosed. The vehicle messaging transmission method, comprises: detecting a vehicle event; and transmitting both a vehicle-to-vehicle message over a vehicle-to-vehicle radio link, the vehicle-to-vehicle message identifying the vehicle event and a vehicle-to-infrastructure message over a vehicle-to-infrastructure radio link, the vehicle-to-infrastructure message identifying the vehicle event. In this way, rather than periodically transmitting location messages, instead messages are only transmitted when a particular event occurs. This helps to reduce the volume of messages since the messages are only transmitted when an event occurs. Also transmitting a vehicle-to-vehicle message enables messages to be transmitted quickly, with reduced latency. Furthermore, because the messages are only sent when an event occurs, privacy and security concerns are reduced. As will be explained in more detail below, transmitting a vehicle-to-vehicle message enables other vehicles which receive the message to receive that message quickly and to respond rapidly to the event, whilst the vehicle-to-infrastructure message can be used to authenticate the validity of the vehicle-to-vehicle message and provide additional assurance to the receiving vehicle that the message is genuine.
Abstract:
Embodiments provide methods, computer programs and apparatuses 10, 30 for a base station transceiver 100 and a relay station transceiver 300 in a mobile communication network 400, which comprises the base station transceiver 100, a mobile transceiver 200 being associated with the base station transceiver 100 and a relay transceiver 300 being associated with the base station transceiver 100. The base station transceiver apparatus comprises a receiver 12 for receiving information on a handover request from the mobile transceiver 200, the information on the handover request indicating that the mobile transceiver 200 is in a situation in which a reception quality of the signals of the relay transceiver 300 would allow a re-association of the mobile transceiver 200 to the relay transceiver 300. The base station transceiver apparatus 10 further comprises a scheduler 14 for scheduling, subsequent to the reception of the handover request, the mobile transceiver 200 for transmission from the base station transceiver 100 to the mobile transceiver 200 on a radio resource on which transmission of the relay transceiver 300 is suspended. The apparatus 30 for the relay transceiver comprises a reception unit 32 for receiving information on a resource assignment from the base station transceiver 100 and a scheduling unit 34 for scheduling the mobile transceiver 220 for transmission or reception on a radio resource which is indicated in the information on the resource assignment.
Abstract:
The control module (16) of the apparatus is operable to relay data packets of the data service between the mobile transceiver (200) and the data server (300). The control module (16) is further operable to determine a control data packet for the data service between the data server (300) and the mobile transceiver (200). The control data packet is intended to maintain a connection established between the data server (300) and the mobile transceiver (200). The control module (16) is further operable to provide a reply data packet for the control data packet to the data server (300) without relaying the control data packet to the mobile transceiver (200), and/or generate and provide the control data packet to the data server (300).

Abstract:
The invention relates to a method for establishing a connectionless bearer service and a method for forwarding data packets in a connectionless bearer service. The data packet has a virtual access network identifier in the header data. The virtual access network identifier defines a unique data path from a source to a destination of the data packet and vice versa. The invention further relates to a network node for forwarding data packets based on a virtual access network identifier received with the data packets and by using a forwarding table for forwarding the data packets.
