METHOD FOR PROCESSING NETWORK CONGESTION, NETWORK DEVICE AND NETWORK SYSTEM

摘要

The present invention discloses a method for processing network congestion, a network device and a network system. The present method comprises: an access network device receives an indication message including an access control mode sent by a mobility management network element, wherein said indication message is sent after the mobility management network element acquires network congestion; the access network device rejects or delays the access of the terminal according to said indication message. The present invention can relieve the network congestion state and avoid the further deterioration of the network congestion.
