Abstract: When triggering a handover request, a source network device requests a measurement indication from a target access network device using the handover request, where the measurement indication indicates the terminal device to measure a channel state of a target cell. In this way, the source network device sends the measurement indication to the terminal device using an RRC reconfiguration message. Then, the terminal device measures the specified channel state of the target cell based on the measurement indication, to obtain a measurement result, and then determines, depending on whether the measurement result meets a handover condition, whether to perform cell handover.

Abstract: The present invention discloses a wireless network access control method and an apparatus. The method includes: configuring, by a wireless network, an independent access control parameter for each network slice, so as to implement differential access control, by the network, on access to different network slices that is initiated by a terminal device. In addition, a core network or a radio access network initiates network slice overload control or a network slice access control parameter adjustment based on resource usage of each network slice in the network. By separately controlling and adjusting the access control parameter of each network slice, it is ensured that impact between network slices is minimized.

Abstract: This application provides a handover method that is based on DC, including: sending, by a source base station, a handover request to a target base station, where the handover request carries a target base station user equipment (UE) aggregate maximum bit rate (UE-AMBR) and/or network slice information of UE; and receiving, by the source base station, a handover request feedback sent by the target base station. A UE capability is coordinated between the source base station and the target base station, so that it is ensured that a technical effect of the UE capability is not exceeded during a DC-based handover. The coordination of the UE capability may be implemented by the source base station, or may be implemented by the target base station.
