摘要： This application provides a data transmission method, a terminal device, and an access network device, so that data can be transmitted between a terminal device and an access network device based on 1 st RRC signaling, without a need of establishing an RRC connection, and signaling overheads required for establishing a bearer for data transmission can be reduced. The method includes: sending, by a terminal device, a first indication to an access network device, where the first indication is used to indicate that the terminal device is to transmit data based on 1 st radio resource control RRC signaling to be sent by the terminal device to the access network device, and/or the first indication is used to indicate that the access network device is to transmit data based on 1 st radio resource control RRC signaling to be sent by the access network device to the terminal device; and transmitting the data between the terminal device and the access network device based on the 1 st RRC signaling.

摘要： Embodiments of this application provide a network handover method and a related device. The method includes: when receiving a user terminal handover request that is sent by a source radio access network node and that carries a target base station identifier, determining, by a source mobility management function entity based on the target base station identifier, to trigger inter-RAT network handover; sending a first message to a source session management function entity; receiving a second message sent by the source session management function entity, where the second message includes a session management context; and sending a relocation request to a target mobility management function entity, where the relocation request is used to instruct the target mobility management function entity to perform inter-RAT network handover on the user terminal. In this way, data continuity in an inter-RAT network handover process is ensured.

摘要： Embodiments of this application provide a data collection method and a communication apparatus. The method includes: receiving, from a terminal device, terminal device-side data of a service and slice information corresponding to the service; and determining, based on the slice information and the terminal device-side data of the service, terminal device-side data corresponding to the slice information. In this solution, when reporting the terminal device-side data of the service, the terminal device also reports the slice information corresponding to the service, so that the terminal device-side data can be associated with the slice information, and collection of the per-slice terminal device-side data is implemented.

摘要： Embodiments of the present invention disclose a communication method, apparatus, and system. The method includes: receiving indication information from an SMF network element, where the indication information indicates that downlink data of a first terminal device arrives at a core network side; and when an eDRX cycle of the first terminal device is greater than or equal to a first threshold, sending an eDRX parameter to a first access network device based on capability information of the first terminal device and capability information of the first access network device, where the first access network device is any access network device in a tracking area TA list of the first terminal device. In embodiments of the present invention, when downlink data of a terminal device arrives at the core network side, and an eDRX cycle of the terminal device is greater than or equal to the first threshold, an eDRX parameter is sent to an access network device based on capability information of the terminal device and the access network device. This can ensure that the access network device can determine a correct paging occasion, thereby ensuring correct paging of the terminal device.

摘要： This application provides a communication method and a communication apparatus. A first network element may obtain first REDCAP information from a terminal apparatus and subscribed second REDCAP information of the terminal apparatus. The first network element determines, based on the first REDCAP information and the second REDCAP information, whether to allow the terminal apparatus to use a service corresponding to the first REDCAP information. The first network element is an access network device or a core network device. Based on this solution, the first network element can verify, by using subscribed REDCAP information of the terminal apparatus, whether the service corresponding to the first REDCAP information can be used, to help ensure that the terminal apparatus uses only a service corresponding to the terminal apparatus, for example, help ensure that the terminal apparatus can use only a service of a first service type by using a REDCAP access technology, and cannot use a service of a second service type by using the REDCAP access technology.
