MACHINE TYPE COMMUNICATION AGGREGATOR APPARATUS AND METHOD

摘要

The present disclosure proposes introducing a multi-tier network topology where some of the MTC devices will play a second role as data aggregators, consolidating data from several other nearby devices and hence reducing the impact on the mobile network. Different radio access technologies (RATs), like Wi Fi or LTE, can be used to aggregate data. Also different Radio Access Networks (RANs) can be used to connect the MTC aggregators to the MTC Application Server. Four aspects of a machine-type- communication aggregator apparatus and method are disclosed: (1) The LTE Mobile Network is used as the backhaul and LTE is also used for aggregator RAT; (2) The LTE Mobile Network is used as the backhaul and Wi Fi is used for aggregator RAT; (3) Mobile Relay based aggregation; and (4) Multi-tier hierarchical aggregators. Limiting overhead impact on the LTE uplink is taught by the disclosure.
