Abstract: A communication method enables a base station to allocate a radio resource to a data packet of a time sensitive networking (TSN) network in a scenario in which the TSN network transmits the data packet through a 5G network. The method includes: obtaining, by an access network device, a first traffic pattern, and allocating a radio resource to a first traffic based on the first traffic pattern. The first traffic pattern includes time information of the first traffic with respect to a first clock. The first clock is a clock used by a first network. The access network device belongs to the first network. The time information includes a time point and/or a period at/in which a data packet of the first traffic arrives at the first network.

Abstract: This application discloses a communication method and apparatus. The method includes: A terminal device receives, in a first cell, configuration information of at least one candidate cell from an access network device; and selects a second cell when a radio link of the first cell meets a first condition (that is, a problem occurs on the radio link of the first cell). If the second cell belongs to the at least one candidate cell, the terminal device is handed over from the first cell to the second cell, and communicates with the access network device in the second cell based on configuration information of the second cell.

Abstract: This application provides a data transmission method and a communication apparatus. The data transmission method includes: A terminal device receives first information from a first access network device, where the first information indicates the terminal device to be handed over and connected to a second access network device. The terminal device sends a first data packet to the second access network device after the terminal device successfully accesses the second access network device, where the first data packet is a data packet that has been sent by the terminal device to the first access network device before the terminal device successfully accesses the second access network device.

Abstract: Embodiments of this application provide an information indication method and apparatus. The method includes: A CP indicates, to a UP by using first information, a maximum number of EHC contexts that can be established by the UP for UE, a DRB of the UE, or a PDU session of the UE in a downlink direction, so that the UP can establish a proper number of EHC contexts for the UE, the DRB of the UE, or the PDU session of the UE in the downlink direction based on the maximum number. This resolves a problem that a UP in an access network device in a split architecture cannot establish a proper number of EHC contexts for the UE because the UP does not know a capability of the UE.

Abstract: A data transmission method and an apparatus. A first core network device obtains a transmission mode of a first service. The transmission mode of the first service is an acknowledged mode or an unacknowledged mode. The first core network device indicates a transmission mode of a first QoS flow to an access network device. The first QoS flow belongs to the first service. According to the method, the access network device can obtain the transmission mode of the first service from the core network device. When a data packet loss or transmission failure occurs, the access network device and a terminal device may determine, based on the transmission mode of the service, whether reliability of unidirectional transmission needs to be improved or reliability of bidirectional transmission needs to be improved.
