Claim One:
1. A user behavior analysis (UBA) method for use in a UBA system associated with a communication network, wherein the UBA system comprises a UBA cloud server, a first UBA subnode and a second UBA subnode, the UBA cloud server is associated with an analysis and decision making layer of the network, and the first and the second UBA subnodes are associated with a probe layer of the network, wherein the UBA cloud server is disposed external to the first and the second UBA subnodes and the UBA cloud server is able to identify network content unrecognizable by the first and the second UBA subnodes, the method comprising: receiving, by the UBA cloud server, a network content identifier in key Internet access information extracted by the first UBA subnode from a user's Internet access information, wherein the network content identifier is reported by the first UBA subnode when no behavior record matching the key Internet access information is found in a local behavior knowledge base of the first UBA subnode; acquiring, by the UBA cloud server, the network content corresponding to the network content identifier; extracting, by the UBA cloud server, a keyword from the network content; updating a behavior knowledge base of the UBA cloud server by using the extracted keyword; and delivering, by the UBA cloud server, the updated behavior knowledge base or updated content of the behavior knowledge base to the first UBA subnode and at least the second UBA subnode, so as to update the local behavior knowledge base of the first UBA subnode and the second UBA subnode.
