Abstract
Methods for grouping MTC devices in MTC networks are proposed. One of the proposed methods includes grouping femto MTC devices into femto groups and grouping macro MTC devices into macro groups, where each of the assigned groups has its granted interval for delivering MTC messages. In the proposed method, it may detect network overload of each group or unsuccessful access request of each device, and statistically count consecutively accumulated number of occurrence of the CN overload of each group or accumulated number of occurrence of unsuccessful access request retries of each device. The group numbers, cycle time, and access probability of the macro groups or the femto groups may be adjusted according to the aforementioned accumulated numbers. In addition, the macro groups or the femto groups are merged or split according to determination based on the statistical counts.
