Abstract

The invention discloses a method and device for controlling adaptive optimization switching for a heterogeneous converged wireless network. The method comprises the following steps: selecting a sensitivity control mode; periodically monitoring network state information of a user terminal and processing the network state information of the user terminal; confirming the current scene of the user terminal according to the processed network state information of the user terminal; confirming a sensitivity parameter value of the user terminal according to the current scene of the user terminal; performing a normalizing operation on all alternative network attributes of the user terminal according to the confirmed sensitivity parameter value; confirming a score of each alternative network by adopting a multi-attribute decision strategy according to a result of the normalizing operation; sorting on the basis of the scores; and confirming a target network, to which a mobile terminal is switched, according to a sorting result and a judging system. According to the method, the ping-pong vertical switching caused in a moving process of the user terminal during is reduced and the user experience for service quality is promoted.
