Methods and arrangements for direct mode communication

摘要

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.

1. A method, implemented in a first user equipment connectable to a second user equipment via a communication network or via a first direct radio communication link, of using a second direct radio communication link for communication between the first and second user equipment, the method comprising:
transmitting, via a network node of the communication network, probe signaling information to the second user equipment, the probe signaling information comprising a first probe token; exchanging, according to the probe signaling information, probe signaling messages including at least one of a second and the first probe token with the second user equipment over the first direct radio communication link; comparing the first and the second probe token; generating a probing report; evaluating the probing report or providing the probing report to the network node or a different node of the communication network or to the second user equipment for evaluation in case of a successful comparison; wherein the probing report is based on content exchanged via the probe signaling messages; using the second direct radio communication link for communication with the second user equipment in response to obtaining instructions to use the second direct radio communication link from an entity by which the probing report was evaluated.
