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 set of channels comprises one or more first channels associated with one or more first node properties and one or more second channels associated with one or more second node properties;
wherein the selection is based on at least one of the following;
the characteristics of the node and the state of the node;
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 of one or more information elements related to one or more properties of the node on the channel.
