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 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

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 (-).

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 the logical channel, and upon reception from the network node entity (eNB), at the user equipment relay (UER), of data received with the identifier (LC_ID_R), the user equipment relay (UER) forwards the received data to the target entity (UET).

Optimized user equipment replaying

An access rights management system is presented in which a mobile device may be allowed to access corporately held data in a flexible manner but in which the security and integrity of the data is maintained. The mobile device is provided with a rights adjustment module which modifies the access rights for locally stored corporate data in dependence on the connectivity of the mobile device with a corporate server.
