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.

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 and a related apparatus are disclosed. The method is performed by a local MBMS functional entity, and includes obtaining local MBMS bearer information by using an interface between the local MBMS functional entity and an MBMS functional entity in a core network, after receiving application layer data sent by a local application server, determining a local MBMS bearer information matching the application layer data, and sending the application layer data based on the local MBMS bearer information matching the application layer data.

Abstract: A communication method and a communications apparatus are disclosed. The method is performed by a control plane function entity and includes: obtaining a correspondence between address information of a user plane function entity and a user plane capability supported by the user plane function entity; receiving a request message from an application server, where the request message is used to request to establish a session for a first service and includes service information of the first service, and the service information includes at least one of broadcast area information and service type information; determining address information of a target user plane function entity based on the correspondence and the service information; and establishing a session connection to the target user plane function entity based on the address information.

Abstract: A data transmission method provided in embodiments of the present application includes: determining, by a mobility management entity MME, that user equipment UE changes from an unreachable state to a reachable state; sending, by the MME, a request message to a serving gateway SGW; receiving, by the MME, downlink data sent by the SGW; and sending, by the MME, the downlink data to the UE. In this way, when the UE changes to a reachable state for downlink data, the MME requests the SGW to send the downlink data, and the MME then sends the downlink data to the UE, thereby avoiding loss of the downlink data caused by delivery of the downlink data to the UE that is in an unreachable state, and improving real-time accuracy of transmission.
