摘要： A quality of service (QoS) parameter processing method and a system, where the method includes a session management function device obtaining a core network (CN) packet delay budget (PDB) between a first access network device and a first user plane function device, and sending the CN PDB to the first access network device via a context update response message, where the first access network device is a target access network device serving a terminal device after a handover. After receiving the CN PDB, the first access network device determines an access network (AN) PDB between the terminal device and the first access network device based on the CN PDB and an end-to-end PDB between the terminal device and the first user plane function device, and then schedules an air interface resource between the terminal device and the first access network device based on the AN PDB.

摘要： A synchronization method and an apparatus are provided to meet a time precision requirement of an industrial factory in a scenario in which a mobile network is connected to an Ethernet network. In an embodiment, a first device determines seventh timestamp information by using timestamp information of receiving and sending packets in a mobile network, so that a second device calculates a time offset between the first device and the second device based on the seventh timestamp information and time points of receiving and sending packets in an Ethernet network, to perform time synchronization. In the method, impact of a transmission delay between the first device and the second device can be avoided, so that a time precision requirement of an industrial factory can be met in a scenario in which the mobile network is connected to the Ethernet network.

摘要： Embodiments of the present disclosure disclose a clock frequency detection method and apparatus. The method includes: dividing a known internal clock frequency range of the system into n frequency intervals, where each frequency interval is corresponding to a frequency detection module, and n is an integer greater than or equal to 2; obtaining a current internal clock frequency of the system, and using the current internal clock frequency as a reference clock frequency; selecting a frequency detection module corresponding to a frequency interval according to the reference clock frequency; and detecting, by the selected frequency detection module, a to-be-detected clock according to a frequency offset range of the reference clock frequency. By using the present disclosure, a risk that an internal clock of the system is attacked may be reduced, and system security may be improved.
