Network Nodes, Devices and Methods Therein for Enabling Device to Device Communication

A method in a second device for enabling device to device, D2D, communication with a first device, which first device is served by a first public land mobile network and the second device is served by a second public land mobile network, comprising;

• transmitting to a first network node of the first public land mobile network, via the second public land mobile network, a request for permission for the second device of roaming to the first public land mobile network enabling the D2D communication, which request requests access to a resource controlled by the first network node of the first public land mobile network, and wherein the request comprises an identity of the first public land mobile network.

(canceled)

A method in a second network node for enabling device to device, D2D, communication between a first device and a second device, which first device is served by a first public land mobile network comprising a first network node and the second device is served by a second public land mobile network comprising the second network node, the comprising:

• receiving from the second device, a request for permission for the second device of roaming to the first public land mobile network enabling the D2D communication, which request requests access to a resource controlled by the first network node of the first public land mobile network, and wherein the request comprises an identity of the first public land mobile network;
• and
• transmitting to the first network node, the request or a permission request, from the second device, for permission for the second device of roaming to the first public land mobile network, which permission request requests access to a resource controlled by the first network node of the first public land mobile network.

A first network node for enabling device to device, D2D, communication between a first device and a second device, which first device is configured to be served by a first public land mobile network comprising the first network node and the second device is configured to be served by a second public land mobile network, comprising:

• a receiving circuit configured to receive, from the second device, via the second public land mobile network, or from the first device, a request for permission for the second device of roaming to the first public land mobile network enabling the D2D communication, which request requests access to a resource controlled by the first network node of the first public land mobile network;
• and
• a deciding circuit configured to decide whether to grant the request based on a position related information of the second device and/or the first device.

(canceled)

A second device for enabling device to device, D2D, communication with a first device, which first device is configured to be served by a first public land mobile network and the second device is configured to be served by a second public land mobile network, comprising;

• a transmitter configured to transmit to a first network node of the first public land mobile network, via the second public land mobile network, a request for permission for the second device of roaming to the first public land mobile network enabling the D2D communication, which request requests access to a resource controlled by the first network node of the first public land mobile network, and wherein the request comprises an identity of the first public land mobile network.
