Mechanism usable for validating a communication device for allowing usage of television radio bands/channels
View Patent ↗There is proposed a mechanism for validating a communication device such as a UE for allowing usage of television radio bands/channels (TVWS). An identification verification process of the communication device is performed by including a unique identification element into an integrity protected and ciphered message related to a radio resource connection reconfiguration procedure, the unique identification element identifying a certified communication device allowed to use radio resources of a television radio band. The message is transmitted to the communication network for performing an identification verification processing with a TVWS database. Furthermore, a mechanism for a handover scenario is provided where validating of the communication device for allowing usage of television radio bands/channels (TVWS) is performed.

if the received handover acknowledgment is positive, perform a handover procedure with the TVBD configured to perform as the target eNodeB, and
the TVBD configured to perform as the target eNodeB includes circuitry configured to
receive the handover request from the source eNodeB requesting the handover of the user equipment (UE);
receive a message from a TV white space (TVWS) database indicating whether the UE is a certified device allowed to use TVWS resources;
if the message from the TVWS database indicates that the UE is a certified device, transmit a positive handover acknowledgment to the source eNodeB; and
after performing a handover procedure, communicate with the UE using the LTE system.
8. The communication system according to claim 7 , wherein the circuitry of the TVBD is further configured to
