1. A method comprising:
- selecting, by a node of a mobile communication network supporting device-to-device communication for direct communication between at least two devices, a channel from a set of channels dedicated for advertising node properties in the mobile communication network;
wherein the selection is based on at least one of the following;
the characteristics of the node and the state of the node; and
wherein an index or position of the channel within the set of channels is indicative of one or more properties of the node; and
broadcasting, by the node, of one or more information elements related to one or more properties of the node on the channel.
