The present invention is directed to licensing data structures for telecommunication systems. The data structures comprise (a) a lock setting or status to permit the contents of the license file for an operational feature to take precedence over the corresponding translation information for the operational feature or to be used as a default setting if there is not corresponding translation information for the operational feature; (b) first and second value settings for an operational feature to permit a value associated with the operational feature to be set anywhere in the range defined by the first and second value settings; and (c) a right-to-use field for an operational feature that is separate from a setting field for the operational feature to provide flexibility in altering the setting field without deleting the operational feature. The present invention further provides a methodology for providing temporary licenses having different features enabled/disabled than a permanent license.
