Anti-high concurrency NB-IOT network communication method and system

The invention discloses an anti-high concurrency NB-IOT network communication method and system. The method comprises the steps of obtaining a control instruction; issuing a paging message according to the control instruction; completing capacity optimization of a paging channel according to the paging signal; and receiving the paging message through the paging channel after capacity optimization,and executing the control instruction according to the paging message. According to the technical scheme of the invention, the capacity of the paging channel is optimized and improved, and the accesscapacity of a base station is optimized, so that the high-concurrency instruction issuing success rate is greatly improved, the problems of time delay and packet loss caused by issuing instructions by a large number of clients at the same moment are solved, hardware investment does not need to be increased, and a lot of cost is saved. The method is further popularized to an NB-IOT downlink high-concurrency application sce
