Abstract

A method in a first user equipment (UE 1) connectable to a second user equipment (UE 2) via a communication network or via a direct radio communication link, of using a direct radio communication link for communication between the UEs is initiated when one of the UEs receives probe signaling information comprising a first probe token via the communication network. The UEs exchange probe signaling messages including a second and/or the first probe token at least partly according to the probe signaling information, such that one of the UEs can compare the probe tokens, generate a probing report and provide the probing report to the communication network, or to the opposite UE for evaluation in case of a successful comparison and such that a direct radio communication link can be used for communication with UE 2 in response to receiving instructions to use the second direct radio communication link from the entity by which the probing report was evaluated.
