1. A method for providing an ad-hoc network, wherein at least one group of mobile devices operating as a device-to-device cluster having a currently elected cluster head device, the method comprising:
configuring, in a network apparatus for the device-to-device cluster, a cluster-specific cell-level radio network temporary identifier C-RNTI on the basis a content-sharing service request being received from a device within the device-to-device cluster, wherein the cluster-specific cell-level radio network temporary identifier C-RNTI is used to identify the device-to-device cluster as a virtual radio access user responsible for transmission between a serving base station and the currently elected cluster head device on behalf of the device-to-device cluster.
