Abstract: A solution for security negotiation during handover of a user equipment (UE) between different radio access technologies is provided. In the solution, the UE receives non-access stratum (NAS) security information and access stratum (AS) security information which are selected by the target system and then performs security negotiation with the target system according to the received NAS security information and AS security information. As such, the UE may obtain the key parameter information of the NAS and AS selected by a Long Term Evolution (LTE) system and perform security negotiation with the LTE system when the UE hands over from a different system, such as a Universal Terrestrial Radio Access Network (UTRAN), to the LTE system.

Abstract: This application provides an RRC connection resume method and apparatus. In the method, when a terminal moves to a target base station, the target base station may reselect, based on a capability and a requirement of the target base station, a first encryption algorithm and a first integrity protection algorithm that are used when the target base station communicates with the terminal, and send the first encryption algorithm and the first integrity protection algorithm to the terminal. On one hand, a security algorithm used for communication between the terminal and the target base station is flexibly selected. On the other hand, because the base station connected to the terminal changes, communication security can be improved by using a new encryption algorithm and integrity protection algorithm.

Abstract: A message protection method and an apparatus are disclosed. The method includes: When a terminal prepares to hand over from a first-standard system to a second-standard system, the terminal may not have a security context of the second-standard system after handover. Therefore, in the method of the present disclosure, the terminal performs integrity protection on a registration request message and a location update request message by using an integrity key in a security context of the first-standard system before handover. Both the registration request message and the location update request message are messages for triggering handover. Therefore, in the method, security protection is implemented on the message for triggering handover, thereby helping improve communication security.
