Abstract: A communication method and apparatus are provided, 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 a 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.

Abstract: The present disclosure relates to communication methods and communication apparatus. In one example method, a centralized unit user plane (CU-UP) obtains a first service feature of a service. The first service feature includes one or more of the following: data that indicates whether the service is a periodic service, a periodicity corresponding to the service when the service is a periodic service, a service packet size corresponding to the service, a service model corresponding to the service, or scheduling time of the service. Then, the CU-UP sends the first service feature to a centralized unit control plane (CU-CP). Next, the CU-CP may send the first service feature to a distributed unit (DU).

Abstract: Example cell measurement methods and apparatus are described. One example method includes obtaining, by a first network device, a first paging parameter of a cell served by a second network device. The first paging parameter is used to indicate a first time domain position at which a terminal device monitors a paging message from the second network device. The first network device sends a reference signal based on the first paging parameter. A time domain position of the reference signal is determined based on the first time domain position.

Abstract: Embodiments of this application provide a communication method, apparatus, and system. The method includes: A terminal device receives first information from a first network device or a second network device, and determines, based on the first information, that it is allowable that the terminal device sends MDT information to the first network device. When it is allowable that the terminal device sends the MDT information to the first network device, the terminal device sends the MDT information to the first network device. This prevents the terminal device from sending the MDT information to the first network device immediately after obtaining the MDT information and avoids disclosure of a network coverage status, thereby effectively and securely using the MDT information.

Abstract: The present disclosure relates to communication methods and network devices. In one example method, a first network device receives a first message sent by a second network device, where the first message is used to notify whether the first network device configures a default data radio bearer (DRB), and the first network device and the second network device are network devices that provide a multi-connectivity service for a same terminal device. The first network device determines, based on the first message, whether to configure the default DRB.

Abstract: The present disclosure relates to communication methods and communications apparatus. In one example communication method, a terminal device obtains measurement configuration information, where the measurement configuration information is used to indicate a target frequency for which logged minimization of drive tests (logged MDT) measurement is performed by the terminal device. The terminal device performs the logged MDT measurement for the target frequency.

Abstract: Example communications systems, methods and network devices are described. One example method includes sending a first message by a first access network device to a core network device to enable the core network device to send a second message to a second access network device, where the first message includes an identity of the second network device. The first message is used to request for X2 transport network layer (TNL) configuration information of a third network device, and the third network device is a network device that has established an X2 connection to the second network device. The first network device receives the X2 TNL configuration information of the third access network device from the second access network device. Therefore, a network device connected to a control plane of a core network can obtain TNL addresses of more network devices that are not connected to the control plane of the core network.

Abstract: The present disclosure relates to mode switching methods, data flow splitting methods, and apparatus. One example mode switching method includes generating, by a first device, first indication information, where a packet data control protocol (PDCP) entity in the first device is connected to at least two radio link control (RLC) entities in a second device, and sending, by the first device, the first indication information to the second device, where the first indication information is used to indicate that transmission between a first RLC entity in the at least two RLC entities and the PDCP entity in the first device is to be canceled. The second device stops the transmission between the first RLC entity and the PDCP entity based on the first indication information.

Abstract: The embodiments of the present disclosure disclose a small data transmission method and a related device and system. The method may include: broadcasting, by a base station, a paging message, where the paging message carries UE identifiers of a plurality of to-be-paged user equipment UE and small data sent to at least one of the to-be-paged UEs, and the small data is data whose data volume is less than a preset data volume threshold. In the present disclosure, small data may be sent to to-be-paged UE while the base station pages the UE, to reduce signaling and time overheads for sending the small data and improving communication efficiency.
