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 for broadcasting from a set of channels dedicated for advertising node properties in the device-to-device communication network; and
selecting an occasion from a set of occasions for applying the channel;
wherein the occasion is selected based on one or more properties of the channel in relation to requirements of the node, andwherein an index or position of the channel within the set of channels is determined based on the selected occasion for applying the channel and independent from the 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.

10. A method comprising:
-
detecting, by a receiving node of a mobile communication network supporting device-to-device communication for direct communication between at least two devices in the mobile communication network; broadcasting, from a sending node, of one or more information elements on a channel in a set of channels dedicated for advertising node properties of the sending node in the mobile communication network and on an occasion dedicated for applying the channel selected from a set of occasions for applying the channel, wherein the occasion dedicated for applying the channel is selected based on properties of the channel and requirements of the sending node; and receiving, by the receiving node, one or more information elements on the channel, wherein the channel is using an index or position determined based on the occasion dedicated for applying the channel and independent from the node properties of the sending node. - View Dependent Claims (11, 12, 13, 14)

15. A method, comprising:
-
configuring a set of channels in a cell of a cellular network dedicated for advertising properties of a node for device-to-device communication; and
informing the node about the configured channels;wherein selection of a channel in the set of channels by the node is based on an occasion dedicated for applying the channel selected from a set of occasions for applying the channel, and wherein selection of the occasion dedicated for applying the channel is based on properties of the channel in relation to requirements of the node; and wherein the index or position of the channel within the set of channels is determined based on the occasion dedicated for applying the channel and independent from the one or more properties of the node. - View Dependent Claims (16, 17, 18)
