Abstract: A communication method, including, when a terminal device is in an idle mode or an inactive mode, a first control plane functional entity that obtains access network information of the terminal device and sends context information of the terminal device to an access network device corresponding to the access network information. Therefore, when the terminal device is in the idle mode or the inactive mode, the first control plane functional entity obtains the access network information of the terminal device and pre-sends the context information of the terminal device to the access network device corresponding to the access network information. When the terminal device needs to transmit data, the terminal device does not need to wait for the process of transmitting the context information of the terminal device, thereby facilitating reducing a delay.

Abstract: A data transmission method may include: receiving, by a core network node, a first packet from user equipment UE or an application server AS; translating the first packet according to non-Internet Protocol IP data transmission information, to obtain a second packet; and sending the second packet using a data transmission channel. The embodiments of the present application further provide a related data transmission device and system. In the embodiments of the present application, a scenario in which a sending party and a receiving party support different protocols is supported by means of packet translation. In addition, performing packet translation according to specific non-IP data transmission information may strengthen negotiation capabilities of the two parties, so that the solution has stronger operability and better practicality.

Abstract: In accordance with an embodiment, the application discloses a communication method, an apparatus, and a system, and relates to the communications field, to help a terminal device in an RRC-inactive state perform a mobility-triggered TAU. The method includes the operations of: in response to determining that a TAI of a location of a terminal device in an RRC-inactive state does not belong to a TAL of the terminal device, switching, by the terminal device, to a CM idle state; sending, by the terminal device, a registration request message to an AMF by using a target RAN node, where the registration request message is used to request to allocate a TAL to the terminal device; and receiving, by the terminal device by using the target RAN node, a registration accept message sent by the AMF, where the registration accept message includes the allocated TAL. Embodiments of this application are applied to a scenario in which the terminal device moves between registration areas.

Abstract: A data processing method and apparatus, and a terminal device are described. The method includes: receiving, by a mobility management device, uplink data sent by a terminal device by using a NAS message, and determining, based on a processing capability of the mobility management device, whether the mobility management device is overloaded; and when the mobility management device is overloaded, instructing, by the mobility management device, the terminal device to transmit the uplink data through a user plane. The data processing method and apparatus may improve communication quality, especially when a bearer between the mobility management device and a service device is not set up, the bearer does not need to be first set up and then released, saving signaling and resources.
