Abstract: Embodiments of this application provide a configuration method and apparatus. When indicating, by using an RRC connection release message, a terminal to enter an inactive state from a connected state, a network device may include, in the RRC connection release message, a configuration parameter allocated to the terminal in the inactive state. That is, the terminal receives the radio resource control RRC connection release message sent by the network device, where the RRC connection release message includes first information used to indicate a target configuration parameter. In this way, the terminal may enter the inactive state based on the RRC connection release message, and determine a context parameter of the inactive state based on the first information, so that the configuration parameter is properly allocated to the terminal in the inactive state.

Abstract: 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.
