Abstract
There is provided an improved solution for performing beacon broadcasting in a device-to-device communication network. The solution comprises selecting, by a node capable of entering a device-to-device communication network, a channel for broadcasting wherein the selection is based on at least one of the following: the characteristics of the node and the state of the node; and causing a broadcast of information related to at least part of the properties of the node on the selected channel.
Claims24
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.
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 by a sending node, one or more information elements related to one or more properties of the sending node, on a channel in a set of channels dedicated for advertising node properties of the sending node in the mobile communication network;
- and
- wherein an index or position of the channel used by the sending node within the set of channels is indicative to the receiving node of one or more properties of the sending node.
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 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.
An apparatus comprising:
- one or more processors and one or more memories including computer program code, the one or more memories and the computer program code being configured, with the one or more processors, to cause the apparatus to perform at least the following:
- selecting a channel from a set of channels dedicated for advertising node properties in a mobile communication network for device-to-device communication in the mobile communication network;
- wherein the selection is based on at least one of the following:
- the characteristics of the apparatus and the state of the apparatus;
- and
- wherein an index or position of the channel within the set of channels is indicative of one or more properties of the apparatus;
- and
- broadcasting of one or more information elements related to one or more properties of the apparatus on the channel.
An apparatus comprising one or more processors and one or more memories including computer program code, the one or more memories and the computer program code being configured, with the one or more processors, to cause the base station to perform at least the following:
- detect broadcasting, by a sending node, one or more information element relating to one or more properties of the sending node on a channel in a set of channels dedicated for advertising node properties of the sending node in a mobile communication network for device-to-device communication in the mobile communication network;
- and
- wherein an index or position of the channel used by the sending node within the set of channels is indicative to the apparatus of one or more properties of the sending node.
An apparatus comprising:
- one or more processors and one or more memories including computer program code, the one or more memories and the computer program code being configured, with the one or more processors, to cause the apparatus to perform at least the following:
- configure a set of channels in a cell of a cellular network dedicated for advertising properties of a node for device-to-device communication;
- and
- send information to the node about the configured channels;
- wherein selection of a channel in the set of channels by the node 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.
