Abstract: This application provides a communications method, apparatus, and system, and a storage medium. In consideration that a synchronization signal and PBCH block (SSB) is introduced into a new radio (NR) system, the first physical cell identifier (PCI) corresponds to a first SSB, and the second PCI corresponds to a second SSB, the first access network device determines, based on the first PCI of the first cell and the second PCI of the second cell, that the first PCI conflicts with the second PCI. In this way, a PCI conflict corresponding to the SSB in the NR system can be detected. This helps eliminate or reduce PCI conflicts in an NR network, improve a success rate of terminal handover, and further reduce a call drop rate.

Abstract: This application provides a communication method and a communication system. A central unit (CU) obtains a quality of service (QoS) parameter of a QoS data flow and performs mapping the QoS data flow to a bearer based on the QoS parameter of the QoS data flow. The CU determines a QoS parameter of the bearer based on the QoS parameter of the QoS data flow and sends a context setup request message to a distributed unit (DU), wherein the context setup request message comprises the QoS parameter of the bearer, the QoS parameter of the QoS data flow and the mapping relationship between the QoS data flow and the bearer.

Abstract: This application provides a wireless connection control method relating to a base station system including a centralized unit and a distributed unit, wherein the centralized unit communicates with the distributed unit, and the distributed unit communicates with a terminal through an air interface. The method includes: first receiving, by the distributed unit, a first message sent by the terminal, where the first message is used to request to establish an air interface control plane connection for the terminal; then sending, by the distributed unit, the first message to the centralized unit; and then receiving, by the distributed unit, a second message sent by the centralized unit, where the second message is used to instruct to establish the air interface control plane connection between the terminal and the distributed unit. The method may implement wireless connection control in a 5G system when functions of a base station are separated.
