Claim of US Patent No. 9,119,218

1. A method for controlling Machine Type Communication (MTC) equipment to access network, in which an access grade or an access
priority is set for an MTC equipment or an MTC group or an MTC service, and a corresponding access parameter is configured
by the network according to the access grade or the access priority; the method comprising:
notifying the access parameter to the MTC equipment or the MTC group or configuring the access parameter onto the MTC equipment
or the MTC group;

initiating, by the MTC equipment or the MTC group, an access request according to the access parameter;
wherein the access parameter comprises an access probability or/and a waiting time; and the step of initiating by the MTC
equipment or the MTC group the access request according to the access parameter comprises:

generating, by the MTC equipment or the MTC group, a random number randomly before initiating the access request, and comparing
the random number with the access probability of the MTC equipment or the MTC group, when the random number is less than or
not greater than the access probability, initiating the access request, otherwise, the access request is not initiated;

when the access parameter contains the waiting time, regenerating a random number after the waiting time expires, and comparing
the regenerated random number with the access probability, when the regenerated random number is less than or not greater
than the access probability, initiating the access request;

when the access parameter does not contain the waiting time, not initiating the access request any more.
