摘要： According to a method and an apparatus in embodiments, in a redirection scenario, a target network device receives, from a terminal device, a first measurement result obtained in a source cell, and configures carrier aggregation CA and/or dual connectivity DC for the terminal device based on the first measurement result. In this way, a network side obtains a measurement result in advance, which reduces a latency between configuring, by a network side device, a measurement configuration for a terminal device after redirection and receiving a measurement result from the terminal device, so that the network side can configure proper CA and/or MR-DC for the terminal device earlier.

摘要： A communication method and apparatus are provided. The method includes: A terminal device sends first data to a network device through a first cell group in an activated state. The terminal device receives a first message from the network device, where the first message is used to deactivate the first cell group. The terminal device changes a state of the first cell group from the activated state to a deactivated state based on the first message of the network device. If the terminal device receives no success acknowledgment of the first data and/or there is second data that has not been transmitted in the first cell group, the terminal device retransmits the first data and/or sends the second data to the network device through a second cell group in an activated state. According to the method and the apparatus, a data loss caused by deactivation of a cell group can be avoided, thereby ensuring lossless data transmission.

摘要： This application provides a cell access method and apparatus. A terminal device can receive RMSI of a cell of a second carrier and BWP information in a cell of a first carrier, and then may learn, based on the RMSI and the BWP information, related information for accessing the cell of the second carrier, to access the cell of the second carrier without first accessing the cell of the first carrier and then being handed over to the cell of the second carrier. This helps implement quick access to the cell of the second carrier and ensures services and performance of the terminal device.

摘要： This application provides a communication method and an apparatus, to resolve a problem that a terminal device may fail to normally communicate with a network side when an SCG is suspended and a link problem occurs in an MCG or signal quality of the MCG deteriorates, so that communication reliability is improved. The communication method and the apparatus are applicable to a communication system of any dual connectivity architecture, such as EN-DC, NGEN-DC, NE-DC and NR-DC. The method includes: When detecting that a link problem occurs in an MCG or signal quality of the MCG is less than a signal quality threshold, a terminal device resumes a suspended SCG, to resume communication between the terminal device and a network side. The MCG is managed by a master node, and the SCG is managed by a secondary node. Further, after the SCG is resumed, the terminal device may send second indication information to the master node via the secondary node. The second indication information is used to indicate the link problem occurring in the MCG or indicate that the link problem occurs in the MCG, to help the master node resume the MCG, so that communication reliability is further improved.

摘要： This application discloses a communication method, including: An access network device generates a candidate conditional handover configuration group, and sends the candidate conditional handover configuration group to a terminal, where the candidate conditional handover configuration group includes one or more candidate conditional handover configurations, and the one or more candidate conditional handover configurations correspond to a flight-related parameter of the terminal; and the terminal obtains a current flight parameter, and determines a target conditional handover configuration from the candidate conditional handover configuration group based on the current flight parameter, where the target conditional handover configuration is used to determine a second cell that the terminal expects to access. In this process, because the candidate conditional handover configuration group generated by the access network device to which a first cell belongs corresponds to the flight-related parameter, the terminal obtains the target conditional handover configuration in the candidate conditional handover configuration group based on a matching result between the current flight parameter and the flight-related parameter. In this way, accuracy of obtaining the target conditional handover configuration is improved, and efficiency of handover to the second cell is improved.

摘要： This application provides a communication method and an apparatus. The method may include: A terminal device determines height information, where a first parameter is related to the height information. The terminal device receives configuration information from a first network device, where the configuration information includes a correspondence between the height information and the first parameter.

摘要： This application provides a cell handover method and a communication apparatus and system, to prevent a terminal device from being handed over to a false access network device. When triggering a handover request, a source network device requests a measurement indication from a target access network device by 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 by 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. Because integrity protection is performed on the RRC reconfiguration message, the false access network device cannot tamper with the RRC reconfiguration message. In this way, the terminal device can determine that the measurement indication is from a genuine target access network device, so that the terminal device can measure a signal of a genuine target cell. Therefore, the terminal device is not handed over to the false access network device.
