Abstract

The embodiment of the invention discloses an access network selection method, a system and communication equipment. The method comprises steps: in response to acquisition of user access information, real-time network state information is acquired from a network awareness analysis system; static policy configuration information is acquired from an ANDSF (Access Network Discovery And Selection Function); and according to the acquired information, access network selection is carried out on the user. The embodiment of the invention can effectively prevent conflicts between an operator strategy for the ANDSF and a dynamic strategy for a PCC (Policy and Charging Control).

Description

technical field [0001] The present invention relates to the field of intelligent pipes, in particular to a method and system for selecting an access network, and a communication device. Background technique [0002] The current access network selection is mainly through the interaction between the network discovery and selection function device (AccessNetworkDiscoveryAndSelectionFunction, ANDSF) and the terminal, using the operator policy in the ANDSF to select the target access network for the terminal, and then realize the intelligent coordination of network access. The selection for the access network is mainly based on static configuration. [0003] The policy and charging rule function device (PolicyControlandChargingRulesFunction, PCRF) includes policy control decision-making and flow-based charging control functions. Input of application function (ApplicationFunction, AF). Among them, the AF mainly provides services, user information and application layer session in...
