摘要： Embodiments of this application provide a communication method, an apparatus, and a system. In this solution, after determining that a connection failure occurs, a terminal device records and sends a first report. The first report includes cell information of a first logical cell, or the first report includes a PLMN identifier of a first logical cell and cell information of a second logical cell. The first logical cell includes a source logical cell and/or a failed logical cell in which the connection failure occurs. The second logical cell includes a 1st logical cell that shares a same physical cell with the source logical cell and/or a 1st logical cell that shares a same physical cell with the failed logical cell. Based on this, a connection failure rate of the terminal device in a RAN sharing scenario can be reduced, and a handover success rate can be improved.

摘要： 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.

摘要： 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.

摘要： The embodiments of the present invention provide a base station, a network controller, and a forward handover method. The base station includes a first base station to which a target cell of user equipment belongs and a second base station to which the user equipment belongs, where the second base station includes: a second processor and a second transceiver, the second processor generates a forward handover indication, and the second transceiver sends the forward handover indication to the first base station, so that when receiving an RRC re-establishment request message of the user equipment, the first base station acquires context information of the user equipment from the second base station according to the forward handover indication. In the foregoing manner, the user equipment can independently select a target cell, and overcomes a disadvantage of violating a basic criterion in the prior art that mobility management is determined and controlled by a network.

摘要： The present disclosure relates to communication methods and apparatuses. In one example method, a communication device performs listen before talk (LBT) detection. The communication device sends first information based on a target event, where the first information includes detection information of the LBT detection. The target event includes any one of that the LBT detection has a potential risk, that a communication process between the communication device and a network device has a potential risk, that the LBT detection fails, and that the communication process between the communication device and the network device fails. The communication process between the communication device and the network device is performed based on the LBT detection.
