Abstract

The invention belongs to the technical field of wireless communication and discloses a terminal autonomous network selection system and a method of wireless heterogeneous network. The terminal detectsand obtains service node information by using ANDSF to form a service node list of the terminal. The terminal obtains the RMI of each node in the service node list by using pilot signal measurement and carrier sensing. The terminal triggers the feature learner, inputs the measured RMI of each node to the feature learner, and outputs the measured RMI as an evaluation value of the link quality of each node. The terminal uses 802.11 u standard and ANDSF to obtain the load information of each node in the service node list. The terminal triggers the policy learner, inputs the obtained link qualityevaluation value and load information of each node to the policy learner, and outputs the obtained link quality evaluation value and load information to the policy learner to select an access node for the terminal. The terminal records the selected node and updates and records the network selection benefit. The invention overcomes the shortcomings of additional signaling overhead and delay causedby adopting server assistance or network assistance.
