Abstract
A method for providing M2M data includes parameterizing M2M data subscriptions by parameters representing a data item to be subscribed, a required period, and a weight; determining, for all of the M2M data subscriptions, a schedule for retrieving data from a front end based on the importance of the data items such that when the actual period with which data updates for a data item can be provided is larger than the required period for the data item a penalty value is added to the weight; modifying the schedule based on the updated weights for retrieving data for the data items such that an overall penalty is minimized and/or an overall actuality of the cached data is maximized; and retrieving data items from the front end and caching the retrieved data from the front end by a back end.
