A communication network system and related devices and method of monitoring in a mobile radio communications network environment direct communications between first and second mobile communication devices to provide to the network an indication of link-quality of the direct communication, wherein the network is arranged to configure at least one of the mobile radio communication devices with a link-quality parameter reference value, the said at least one mobile radio communications device can report to the network if it determines, relative to the said reference value, that the link-quality of the direct communication is insufficient, and if required the network can subsequently control communication between the said first and second mobile radio communication devices responsive to the reporting the received from the said at least one mobile radio communications device, or the network can employ the reporting from the said at least one mobile radio communications device for network planning/optimization purposes.

Communication system, apparatus and related methods of operation

The present invention provides for a wireless communication method and relaxed system and wireless terminal devices arranged for communication between first () and second () wireless terminal devices by way of direct communication, for example by way of a DD link, in a network environment, the method and system and, as appropriate, devices, being arranged to provide for the delivery of link-quality parameter information from at least one of the two terminal devices to the network for communications interaction by the network with communication between for the two terminals in direct communication.

Direct communication between mobile radio communication devices

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

A system is disclosed in which a UE-Relay receives, from a user communication device, a message requesting the provision of a communication link (e.g. a Layer 2 link) between the user communication device and a network serving the user communication device. The UE-Relay communicates with its core network, responsive to the received message, to establish the communication link from the user communication device to a base station remote from the UE-Relay; and relays data, between the user communication device and the base station using the communication link.

Relaying user communication device enabling RRC, NAS connections, user communication device, base station, system, method, and non-transitory computer readable medium storing a program

The present invention provides for a wireless communications method and related system and wireless terminal devices arranged for communication between first () and second () wireless terminal devices by way of direct communication, for example by way of a D2D link in a network environment, the method and system and, as appropriate, devices, being arranged to provide for the delivery of link-quality parameter information from at least one of the two terminal devices to the network for communications interaction by the network with communication between for the two terminals in direct communication.

A communication system is disclosed in which a relay communication device identifies a service to be received by at least one other communication device and also identifies the at least one communication device. The relay communication device maintains a mapping between services and the communication device(s) that need to receive that service. The relaying communication device receives service data using a broadcast/multicast bearer and forwards, using a respective device-to-device bearer, the service data to each communication device for which a respective mapping to that particular service is maintained.

Communication system

A communication system () is disclosed in which a relaying user device (UE-R) (-) obtains bit rate information (e.g. aggregate maximum bit rate, AMBR) for relaying data for another (relayed) user device (UE) (--). The obtention of said bit rate information may by receiving a message from the another (relayed) device, UE, for registering the UEto an application server, AS (PSCC). The registration message may comprise UEidentity, UE-R identity and information identifying a bit rate required by the UEwhile communicating via the UE-R (e.g. an AMBR parameter such as Relay-APN-AMBR). The UE-R sends the registration message received from the UEto a core network () node (e.g. a gateway device like a P-GW or S-GW, an MME, or a PCRF) comprising the information identifying a bit rate for relaying communication data for the UE (--) to which the bit rate information relates. The UE-R (-) relays data received from the UE (--) to a base station (), and relays data for the UE (--), received from the base station (), to the UE (--).

Controlling data rate at a relay UE (UE-R) for relaying traffic to and from a relayed UE

A communication system () is disclosed in which a core network node () generates configuration data including a first parameter for controlling data throughput (such as an aggregate maximum bit rate value) for a relaying user device (-) in dependence on whether or not the relaying user device (-) has a relaying connection with another user communication device (--). The core network node () transmits the generated configuration data to another network node () for managing communications with the relaying user device (-).
