Method and system for managing data

An M2M frontend (FE), comprising:

• one or more processors that collectively provide a plurality of filtering modules, each of the filtering modules configured to implement one or more of a plurality of filters so as to perform data filtering by:
• a) calculating, for each of the plurality of filters, a threshold Quality of Information (QoI) value,
• b) receiving, from one of a plurality of devices, M2M data of a particular category,
• c) selecting a filter corresponding to the category of the received M2M data,
• d) applying a filtering function of the selected filter to the received M2M data so as to provide a forwarding decision for the received M2M data, and
• e) performing, based on the forwarding decision, forwarding the received M2M data to an M2M backend (BE) or discarding the received M2M data,
• wherein each of the plurality of filters of the M2M FE provides a QoI assessment method, wherein each of the plurality of filters has a different QoI assessment method, a different calculated threshold QoI value, and a different number of thresholds.

A machine-to-machine (M2M) system, comprising:

• an M2M backend (BE);
• one or more devices configured to communicate with the M2M BE via an M2M frontend (FE);
• and
• the M2M frontend, including one or more processors that collectively provide a plurality of filtering modules, each of the filtering modules configured to implement one or more of a plurality of filters so as to perform data filtering by:
• a) calculating, for each of the plurality of filters, a threshold Quality of Information (QoI) value,
• b) receiving, from one of the plurality of devices, M2M data of a particular category,
• c) selecting a filter corresponding to the category of the received M2M data,
• d) applying a filtering function of the selected filter to the received M2M data so as to provide a forwarding decision for the received M2M data, and
• e) performing, based on the forwarding decision, forwarding the received M2M data to the M2M backend (BE) or discarding the received M2M data,
• wherein each of the plurality of filters of the M2M FE provides a QoI assessment method, wherein each of the plurality of filters has a different QoI assessment method, a different calculated threshold QoI value, and a different number of thresholds.
