Network Synchronisation of Devices in a D2D Cluster

摘要

The invention relates to an apparatus including at least one processor and at least one memory including a computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to: convey timing information parameters and information on statuses of validity timers of devices belonging to a device cluster and being in a network communication mode for network synchronization purposes to a master device of a device cluster, and obtain at least one re-source request for network synchronization from the master device of the device cluster on behalf of at least one device belonging to the device cluster and being in the network communication mode or in a network idle mode, and communicate with the master device of the device cluster for providing network synchronization.

1. An apparatus comprising:
at least one processor and at least one memory including a computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to:
obtain timing information parameters and statuses of validity timers of devices belonging to a device cluster and being in a network communication mode; monitor a need for uplink synchronization using the timing information parameters and/or the statuses, and if a need for network synchronization exists, control synchronization to a serving network node.
