providing an indication of said instant device-to-device radio access resources to said user equipment for use within the at least one service coverage zone for device-to-device communications mode between said user equipment and at least one of the plurality of road side units, and/or between said user equipment and at least one other user equipment; and
providing an indication of said allocated instant device-to-device radio access resources to at least one neighboring road side unit within the at least one coverage service zone for use in coordination of resources with the at least one neighboring road side unit.
2. The method according to claim 1 , wherein the instant device-to-device based radio access comprises one to many broadcast based device to device communication using the allocated resources.
3. The method according to claim 1 wherein said allocated resources are associated with the at least one service coverage zone.
4. A method comprising:
causing, by a user equipment, a request to be sent to a network node for resource allocation for at least one service coverage zone in a coverage area of a first network, the first network comprising a plurality of road side units forming a synchronized sub-network, said plurality of road side units configured to provide the user equipment with at least one of instant device-to-device based radio access and cellular access, wherein the sub-network is associated with at least one cellular network which provides cellular access over the coverage area of the first network and wherein said request comprises service coverage zone and/or user context information;
receiving a first indication of allocated instant device-to-device radio access resources for use within the at least one service coverage zone for device-to-device based communications mode with at least one of the plurality of road side units, and/or with at least one other user equipment; and
providing a second indication of said allocated instant device-to-device radio access resources to at least one neighboring road side unit within the at least one coverage service zone for use in coordination of resources with the at least one neighboring road side unit.
5. The method according to claim 4 , wherein the instant device-to-device based radio access comprises one to many broadcast based device to device communication using the allocated resources.
6. The method according to claim 4 , wherein said first indication of the allocated instant device-to-device radio access resources comprises service coverage zone identity and instant radio access resource information.
7. 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:
receive a request from a user equipment for resource allocation for at least one service coverage zone in a coverage area of a first network, the first network comprising a plurality of road side units forming a synchronized sub-network, said plurality of road side units configured to provide the user equipment with at least one of instant device-to-device based radio access and cellular access, wherein the sub-network is associated with at least one cellular network which provides cellular access over the coverage area of the first network, and wherein said request comprises service coverage zone and/or user context information;
allocate instant device-to-device radio access resources for the user equipment for use within the at least one service coverage zone;
provide an indication of said instant device-to-device radio access resources to said user equipment for use within the at least one service coverage zone for device-to-device communications mode between said user equipment and at least one of the plurality of road side units, and/or between said user equipment and at least one other user equipment; and
provide an indication of said allocated instant device-to-device radio access resources to at least one neighboring road side unit within the at least one coverage service zone for use in coordination of resources with the at least one neighboring road side unit.
8. The apparatus according to claim 7 , wherein the instant device-to-device based radio access comprises one to many broadcast based device to device communication using the allocated resources.
9. The apparatus according to claim 7 , wherein said allocated resources are associated with the at least one service coverage zone.
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:
cause, by a user equipment, a request to be sent to a network node for resource allocation for at least one service coverage zone in a coverage area of a first network, the first network comprising a plurality of road side units forming a synchronized sub-network, said plurality of road side units configured to provide the user equipment with at least one of instant device-to-device based radio access and cellular access, wherein the sub-network is associated with at least one cellular network which provides cellular access over the coverage area of the first network and wherein said request comprises service coverage zone and/or user context information;
receive a first indication of allocated instant device-to-device radio access resources for use within the at least one service coverage zone for device-to-device communications mode with at least one of the plurality of road side units, and/or with at least one other user equipment; and
provide a second indication of said allocated instant device-to-device based radio access resources to at least one neighboring road side unit within the at least one coverage service zone for use in coordination of resources with the at least one neighboring road side unit.
