The invention discloses a
system, a device and a method for multi-
network integration. The
system comprises an application gateway
server and a unified account management
server, wherein the application gateway
server is used for resolving
a domain name in an access request sent from a
client to an application
system, acquiring an
authentication notification based on the acquired resolved address, and establishing a communication connection between the
client and the application system based on the notification; the unified account management server is used for performing
authentication on anaccount corresponding to the resolved address, and notifying the application gateway server if the
authentication is passed. The method comprises the following steps of: resolving the
domain name in the access request sent from the
client to the application system, acquiring the authentication notification based on the acquired resolved address, and establishing the communication connection between the client and the application system. The system, the device and the method for the multi-
network integration can overcome the defects of incapability of uniformly accessing and managing multiple networks, complex account
application procedure, poor safety, low efficiency and the like to realize uniform access and management of the multiple networks, simplify the account
application procedure,and improve the safety and the efficiency.
