A communications system is provided. A network device controls the setting up of a device to device communication link, as sent between a device in the core network and the base station(s) servicing the relevant mobile devices, including disclosure of the common security information for two mobile devices to communicate securely over the direct device to device communications link.

Core network, user equipment, and communication control method for device to device communication

The invention provides for a wireless communications terminal (), and related system and method, for wirelessly communicating with a network (). The terminal () is arranged to transmit, as part of a wireless connection establishment procedure for forming a wireless connection between the terminal () and the network (), wireless-connection establishment signalling () including a small-data indicator to indicate to the network () that transmission of an amount of data below a threshold value is required from the terminal () by way of the wireless connection to the network ().

Wireless network device and user equipment, and method and system for wireless communication

User equipment for wireless network communication, method of operating same, network device for wireless communication and wireless communication system

A system is disclosed in which a communication device provides measurement reports to a communication network. The communication device connects to a cell of the network and receives configuration data for at least one relay specific trigger event for triggering measurement reporting for at least one relay cell operated by a relay device for the base station. The communication device performs measurements and sends a measurement report to the communication network when the trigger event has occurred.

Communication device and a method thereby, a base station and a method thereby, and a system

A mobile device () configured to provide relay capabilities in a communications system () by communicating network-level mobile device relaying capabilities and radio-level mobile device relaying capabilities from the mobile device () to a communications node () of the communications system () so that the mobile device () can relay communications between the communications node () and another mobile device (). User subscription information related to relaying is also disclosed.

Mobile communications device and system

The invention relates to a method for relaying a communication in a network, wherein a user equipment (UER) relays a communication between a network node entity (eNB) and a target entity (UET), the method including the steps, generating a logical channel at least between the user equipment relay (UER) and the target entity (UET), and assigning at least one identifier (LC_ID_R) to said logical channel, and upon reception from the network node entity (eNB), at the user equipment relay (UER), of data received with said identifier (LC_ID_R), the user equipment relay (UER) forwards the received data to the target entity (UET).

Optimized user equipment supporting relay communication, and related method

Wireless network device and user equipment, method and system for wireless communication that provides an indicator for operating in a small data transmission mode

The invention provides for a wireless communications terminal (), and related system and method, for wirelessly communicating with a network (). The terminal () is arranged to transmit, as part of a wireless connection establishment procedure for forming a wireless connection between the terminal () and the network (), wireless-connection establishment signaling () including a small-data indicator to indicate to the network () that transmission of an amount of data below a threshold value is required from the terminal () by way of the wireless connection to the network ().

Wireless communication terminal and method for wireless communication that incorporates a small-data indicator for establishing wireless connection with a network

A mobile communications system is described in which the network configures a mobile relay node that is mounted in a moving vehicle (such as a train) with expected tracking area information for the route along which the vehicle is expected to travel. UEs associated with the mobile relay node are provided with the list and do not perform tracking area updates if the movement of the vehicle corresponds to the stored list. Where advance knowledge of the route is not available, the mobile relay node is configured with a fixed tracking area and a fixed radio cell so that associated UEs do not detect a change in the tracking area or in the radio cell and so do not perform tracking area updates towards the network or the network does not need to control the UEs mobility while having a radio connection with the network.
