Abstract: Embodiments of this application relate to the field of communication technologies, and provide a timing method for dealing with a link exception and an apparatus. A specific solution is as follows: receiving a first synchronization packet from a first terminal device; receiving a second synchronization packet from a second terminal device or a server; and if the first synchronization packet and the second synchronization packet belong to a same TSN domain, determining a to-be-forwarded synchronization packet in the first synchronization packet and the second synchronization packet. In this way, if the to-be-forwarded packet is the first synchronization packet, the first synchronization packet is forwarded, and the second synchronization packet is filtered. Embodiments of this application are used to improve timing precision in a timing process of the TSN device for the 5GS.

Abstract: A communications method and apparatus are provided. The method includes: A first access network device sends a first message to a core network device, where the first message is used to indicate to suspend one or both of a first PDU session and a second PDU session. The first PDU session and the second PDU session are PDU sessions that are established as requested by a same terminal, and are used to transmit a duplicated data packet. According to the method, when a condition for implementing reliable transmission is not met, the core network device can be indicated to suspend the PDU session. In this way, a PDU session does not need to be re-established, and signaling overheads for establishing the PDU session are saved.

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.
