Step S902:MTC device can receive the message I and message II of network side broadcast, meeting after receiving at work This two parts content is updated and stored inside it.

Step S903:When MTC device has access demand, it will be according to itself current access grade and in being stored in The message I in portion content determines applicable urgency calculation criterion, and the access urgency of itself is calculated according to this criterion.

Step S904:Its is tight according to itself access grade and the message II for being stored in inside Content inspection for MTC device Anxious degree whether be more than place access grade it is current allow access urgency.If greater than step S905 will be continued, otherwise continue Step S906.

Step S905:MTC device is initiated access request and accessed, then flow terminates.

Step S906:The delay stand-by period of MTC device access grade according to where being stored in its in the message II of inside, A random value is produced within this delay stand-by period of zero-sum, delay wait is carried out in the time of this random value;Waiting time, MTC device can continue to the message I and II of network side broadcast and update storage;Delay terminates, and MTC device goes to step Continue to carry out downwards at S903.

In summary, can effectively solve a large amount of variety classes MTC devices in network to be present the invention provides one kind and connect Enter the method that network produces congestion.This method is during congestion control is implemented, the comprehensive actual motion for having taken into account network side Situation and the various actual conditions at MTC device end.This method accesses network congestion methods phase with MTC device of the prior art Than major advantage is that the access demand situation of a large amount of MTC devices in identical access grade is to go to calculate according to certain criterion Urgency rather than determined by generation random number, this can avoids the MTC device of urgent need due to caused random Number is bad and loses the situation of access chance and occurs.In addition, the method for the present invention can also be to the difference in identical access grade MTC device is managed collectively using urgency, improves the autgmentability of system.Finally, can also be according to the real-time shape of network Condition adjusts the urgency calculation criterion of different access grades, to improve the laser propagation effect of network.
