<p>A method for network access is provided, including: the central policy decision function building up a relationship between the user and the related distribution or access policy function based on the user routing information sent by the distribution or access policy function and the information of the distribution or access policy function. A system for network access is also provided. In the process of the user performing network access, the relationship between the user and the A-RACF of the current network he or she stays in is dynamically built up in the SPDF, which is to say, the topology relationship between the SPDF and the A-RACF is dynamically built up. Thus, when the AF sends a resource request to the SPDF, the SPDF can find the A-RACF the SPDF belongs to based on the relationship between the user and the A-RACF, so that the automatic topology discovery between SPDF and A-RACF can be implemented and the normal user network access can be ensured.</p> |
