Classification: CPC H | IPC H

Claim 5:
6. A network node for a wireless communication network, the network node configured to provide location assurance services for verifying a location of data stored on at least one storage device within at least one cell area served by the network node, the network node comprising:
a communication interface; and
processing circuitry, the processing circuitry configured to:
cause the communication interface to communicate with at least one location assurance gateway located in a data center within the at least one cell area for location information, the location information being used to verify a location of the data stored on the at least one storage device, the communication of the network node with the at least one location assurance gateway including transmitting, to the at least one location assurance gateway, at least one code, the at least one code being the location information used to verify the location of the data and each of the at least one code being configured to be unique to the at least one cell area as compared to other cell areas of the wireless communication network, the at least one code being a sequence of codes, each of the sequence of codes being configured to be unique to the one cell area as compared to other cell areas of the wireless communication network, each of the codes in the sequence of codes being configured to be unique to a time period, as compared to other time periods associated with a predetermined periodic interval at which each of the codes in the sequence of codes is communicated, and storing the at least one code in a database associated with the network node;
receive a user-requested location verification request of the data stored on the at least one storage device, the user-requested location verification request including at least one code, the verification being performed by comparing at least one code from a user-requested location verification request to the at least one code stored in a database associated with the network node, the location being verified when the at least one code from the user-requested location verification request matches the at least one code stored in the database associated with the network node;
compare the at least one code from the user-requested location verification request to at least one code stored in the database associated with the network node;
in response to the user-requested location verification, communicate at least one indication of a location of the at least one location assurance gateway corresponding to the at least one code from the user-requested location verification request; and
broadcast each of the at least one code by the at least one network node as a short message service-cell broadcast, SMS-CB, message within the at least one cell area at a predetermined periodic interval.
