Network nodes, a user equipment and methods therein for enabling D2D communication

摘要

A method performed by a network node for enabling network-assisted Device-to-Device, D2D, communications between user equipments configured to be in a wireless telecommunications network is provided, wherein the network node is configured according to a Radio Access Technology, RAT, that cannot be used for D2D communications. The network node determines D2D assistance information to enable network-assisted D2D communications by the network node. The network node then transmits the D2D assistance information to at least one user equipment. A user equipment, another network node and methods performed therein are also provided.

1. A method performed by a network node to enable network-assisted Device-to-Device (D2D) communications between user equipments configured to be in a wireless telecommunications network, wherein the network node is configured according to a Radio Access Technology (RAT) that cannot be used for D2D communications, the method comprising:
determining D2D assistance information to enable network-assisted D2D communications by the network node, wherein the determining further comprises determining that connectivity for at least one user equipment to a core network node is available via the network node, wherein the core network node provides assistance to applications and/or services of D2D communications in the at least one user equipment, and wherein the core network node is separate from the network node; and transmitting the D2D assistance information from the network node to the at least one user equipment, wherein transmitting further comprises transmitting an indication of the connectivity to the at least one user equipment as part of the D2D assistance information.
