In 301-302, a terminal UE sends a QoS guarantee request to an SP, the SP sends the guarantee request to an AF, and the AF generates a token.

In 303-306, transmitting the token to a RAN (Wireless Access Network, radio Access Network) side in the dedicated load establishing process includes: the AF sends the token to the PCRF through the AAR and receives the feedback of the PCRF, the PCRF sends the token to the MME and the S/PGW through the RAR, the MME and the S/PGW send the dedicated bearer establishment request to the RAN and carry the token, and then the dedicated bearer establishment operation between the UE and the network in step 307 may be performed.

In 309-310, the AF delivers the token to the terminal through the guarantee response.

In some embodiments, 303 and 309 may be performed synchronously, not sequentially.

In 311, the UE carries the token to directly request for security from the RAN side, and obtains the permission after the RAN verification is passed, so that the subsequent terminal and the RAN side can directly interact with each other to obtain a security procedure.

In some embodiments, the RAN-side authentication procedure may be as shown in fig. 4.
