The present invention provides a method, a system, and a device for correlating user-associated information in a network attachment subsystem, including: a Network Access Configuration Function entity, NACF, transmits the user-associated information 1 containing predetermined correlation information to a Connectivity Session Location Function entity, CLF, a User Access Authorization Function entity, UAAF, transmits the user-associated information 2 containing predetermined correlation information to the CLF, and the CLF correlates dynamically the user-associated information 1 with the user-associated information 2 in accordance with the predetermined correlation information. In the present invention, the CLF may correlate the user-associated information transmitted from the UAAF and the Network Access Configuration Function entity dynamically. Therefore, the present invention may avoid the procedure of statically configuring partial correlation information in the CLF, and may simplify the user-associated information correlating process. The present invention provides a practical, convenient, quick and simplified method for correlating user-associated information for roaming/nomadic Customer Premises Equipments, and thereby attains the purpose of enhancing flexibility of the user-associated information correlation method and improving the user-associated information correlation mechanism.
