2. The apparatus of claim 1 , further comprising causing the apparatus to:

obtain a request from a public safety network to provide access for public safety users and assistance for public safety usage over a service area of interest.

3. The apparatus of claim 1 , wherein the commercial user device is selected based on a suitable service area, location and capability information.

4. The apparatus of claim 1 , further comprising causing the apparatus to:

control the mobile relay agent and/or the mobile relay and device-to-device operations for public safety usage.

5. The apparatus of claim 1 , wherein the public safety device is selected among the public safety devices which have roamed and got access to a commercial network.

6. The apparatus of claim 1 , wherein the public safety device is selected among the public safety devices which have roamed and got access to a commercial network and wherein the public safety device uses the commercial network for communicating with its command centre or server in a public safety network.

7. The apparatus of claim 1 , wherein the configuring further comprises causing the apparatus to:

configure a selected device to broadcast information to public safety users to enable them to get access to public safety services.

8. The apparatus of claim 1 , further comprising causing the apparatus to:

couple the public safety device selected to operate as a mobile gateway for public safety usage to a commercial network for backhauling via the user device to operate as a mobile relay agent for public safety usage.

9. The apparatus according to claim 1 , wherein the commercial user device is selected and configured to operate as the mobile relay agent for public safety usage.

10. An apparatus comprising:

at least one processor and at least one memory including a computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to:

request mobile backhaul services from a commercial network, and

obtain a configuration message from the commercial network to operate as a mobile relay and/or a mobile gateway for public safety usage, wherein the mobile backhaul services are provided by the commercial network and by using commercial resources, and device-to-device communications for the public safety usage are provided by using public safety resources.

11. The apparatus of claim 10 , wherein the configuration message is originated from a public safety network or from a request made by the public safety network.

12. The apparatus of claim 10 , further comprising causing the apparatus to:

use the commercial network for communicating with its command centre or server in a public safety network.

13. The apparatus of claim 10 , further comprising causing the apparatus to:

broadcast information to public safety users to enable them to get access to public safety services.

14. The apparatus of claim 10 , the apparatus comprising a user device of the commercial network or a public safety network, when configured to operate as the mobile relay and/or the apparatus comprising a user device of the public safety network, when configured to operate as the mobile gateway.

15. The apparatus according to claim 10 , wherein the apparatus is a commercial user device.

16. A method comprising:

selecting and configuring a commercial user device to operate as a mobile relay agent for public safety usage and/or a public safety device to operate as a mobile relay and/or a mobile gateway for public safety usage;

allocating a public safety specific spectrum to device-to-device communications for the public safety usage, and

providing mobile backhaul services by using commercial resources, wherein the mobile backhaul services are provided by a request obtained from the public safety device or a public safety network.

17. The method of claim 16 , further comprising:

obtaining a request from a public safety network to provide access for public safety users and assistance for public safety usage over a service area of interest.

18. The method of claim 16 , wherein the commercial user device is selected based on a suitable service area, location and capability information.

19. The method of claim 16 , further comprising:

controlling the mobile relay agent and/or the mobile relay and device-to-device operations for public safety usage.

20. The method of claim 16 , wherein the public safety device is selected among the public safety devices which have roamed and got access to a commercial network.

21. The method of claim 16 , wherein the public safety device is selected among the public safety devices which have roamed and got access to a commercial network and wherein the public safety device uses the commercial network for communicating with its command centre or server in a public safety network.

22. The method of claim 16 , wherein the configuring further comprises:

configuring a selected device to broadcast information to public safety users to enable them to get access to public safety services.

23. The method of claim 16 , further comprising:

coupling the public safety device selected to operate as a mobile gateway for public safety usage to a commercial network for backhauling via the user device to operate as a mobile relay agent for public safety usage.

24. The method according to claim 16 , wherein the commercial user device is selected and configured to operate as the mobile relay agent for public safety usage.

25. A method comprising:

requesting mobile backhaul services from a commercial network, and

obtaining a configuration message from the commercial network to operate as a mobile relay and/or a mobile gateway for public safety usage, wherein the mobile backhaul services are provided by the commercial network and by using commercial resources, and device-to-device communications for the public safety usage are provided by using public safety resources.

26. The method of claim 25 , wherein the configuration message is originated from a public safety network or from a request made by the public safety network.

27. The method of claim 25 , further comprising:

using the commercial network for communicating with its command centre or server in a public safety network.

28. The method of claim 25 , further comprising:

broadcast information to public safety users to enable them to get access to public safety services.

29. The method according to claim 25 , wherein the method is performed by a commercial user device.
