rrc message for example it may extend the measurement report message or define a new rrc message the subsequent procedures are very similar to those in the explicit method using a non access layer message and thus the detailed description thereof is omitted in addition to the activation or deactivation of the extra low power consumption state as stated above there are still many scenarios where the mtc device will always dynamically activate various features based on the measurement mechanism or certain events and inform the network for example the mtc device used for medical sensing will transmit only a small amount of data to the user of the mtc device periodically in general scenarios however if an emergent event occurs the priority alarm feature may be activated and the mtc device may transmit an emergent alarm message to the network as well as a large amount of detected medical data therefore the mtc device needs to actively inform the network of activation or deactivation of its priority alarm feature it is apparent that the explicit methods for activation or deactivation of the extra low power consumption feature may also be used for activation or deactivation of other features fig4 illustrates schematic diagrams of the structure of the mtc device according to embodiments of the present invention in fig4 a a schematic diagram of a general mtc device 400 with the feature activation deactivation function of the present invention is illustrated the mtc device 400 includes a first.
