Abstract:
1. A method for a network application function unit (NAF) of a third generation wireless communication network to verify validity of a user, comprising: receiving an application request message containing a transaction identifier (TID) from a user equipment device (UE) of the user, checking whether there is information of the TID stored in the NAF; wherein if the BSF finds the TID inquired by the NAF, the BSF returns to the NAF a response message of success containing the information of the TID and the term of validity of the TID, and the method further comprises: storing the information of the TID and the term of validity of the TID in the response message and making normal communications with the UE; or if the BSF fails to find the TID inquired by the NAF, the BSF returns to the NAF a response message of failure, and the method further comprises: instructing the UE to perform a bootstrapping authentication with the BSF.
