The invention discloses an electric power IMS state presentation service flow control method and system in the technical field of electric power communication networks. The objective of the inventionis to solve the technical problems that after an SIP public protocol is adopted by an electric power IMS access network terminal in the prior art, a server generates a large amount of message signaling flow due to the fact that the state presents the total online characteristic of a service, a high-load condition occurs in an electric power communication network, and the performance of an IMS network is seriously influenced by electric power. The method comprises the following steps: acquiring release request information in response to a client release request; analyzing the obtained release request information to obtain client state information, and reporting the client state information to a state server; counting an updating time interval of the state information in a set time period; and controlling a state server to push state information to the subscription client in a delayed manner according to the updating time interval.
