Network connection recovery method and system

摘要

When a terminal device accesses through a communication network for the first time, a server device generates an identifier for use in reconnection of the terminal device with the communication network, and returns the identifier to the terminal device. If a connection between the terminal device and communication network is broken by a fault, the server device authenticates the terminal device using the identifier transmitted from the terminal device to recover said connection with another terminal device to which said terminal device had been connected immediately before the terminal device was disconnected from the communication network.
