Embodiment Construction

[0077] The basic idea of ​​the present invention is: when the network side determines that the random access load exceeds the set threshold, it releases access control adjustment parameters to the terminal to adjust the terminal's access control; before the terminal initiates random access, it obtains Access control adjustment parameters, the terminal uses the access control adjustment parameters to adjust its own original access control parameters, and then performs access control according to the adjusted parameters. Wherein, the terminal obtains the access control adjustment parameter from the network side before initiating random access, which means that the terminal can obtain the access control adjustment parameter from the network side before generating an event that triggers random access; After the incoming event, and before starting the random access process, access control adjustment parameters are obtained from the network side.

[0078] The network side can send t...

Abstract

The invention discloses a method for adjusting terminal access control. The method comprises that: network side releases an access control and adjustment parameter; and the terminal adjusts an access control parameter according to the access control adjustment parameter obtained from the network side before initiating random access and carries out access control according to the adjusted access control parameter. The invention further discloses a system for adjusting the terminal access control. In the invention, when a random access load exceeds a set threshold, random access control adjustment can be carried out on a set terminal, or a terminal group, or the like. The random access control on the terminals is realized by releasing the access control adjustment parameter to the terminals, thereby reducing the load of the current random access, guaranteeing the success rate of the terminal random access, and promoting service quality of a system.

Description

technical field [0001] The present invention relates to a terminal random access control method, in particular to a terminal access control adjustment method and system based on a machine-to-machine communication (M2M, Machine to Machine) system. Background technique [0002] Human-to-human communication (H2H, Human to Human) refers to the communication achieved by people through the operation of equipment. The existing wireless communication technology is developed based on H2H communication, while machine-to-machine communication (M2M, Machine to Machine) broadly The definition of Internet of Things is networked applications and services centered on the intelligent interaction of machine terminals. M2M is based on intelligent machine terminals and uses various communication methods as access means to provide customers with informatization solutions to meet customers' informatization needs in monitoring, command and dispatch, data collection and measurement. [0003] M2M b...
