  • Patent number: 11665598
    Abstract: A method for batch handover authentication and key agreement oriented to a heterogeneous network generally includes the following steps: A, system establishment and participant registration: users participating in authentication register on the LTE-A network to obtain their respective identity information; B, access authentication: when a large number of users request access to the WLAN, the target network WLAN is discovered by using the ANDSF, and the leader sends a complete group authentication message to the AAA server of the WLAN to request identity authentication; if the authentication succeeds, the AAA server of the WLAN returns an identity authentication response; C, if the authentication fails, the continued execution of the protocol is terminated. The method effectively realizes batch authentication of users during handover from the LTE-A network to the WLAN, and thus has high authentication efficiency, small signaling overheads, and high security.
