Abstract: The present invention provides a data processing method, a node, a structure, and an apparatus. The method includes: receiving, by an aggregation node, a first non-access stratum message sent by user equipment UE, where the aggregation node includes at least two types of interfaces, and each type of interface is used to receive a first non-access stratum message of one radio access technology RAT type; converting, by the aggregation node, the first non-access stratum message into a non-access stratum message in a first format based on a RAT type of the first non-access stratum message, where the first format is a non-access stratum message transmission format supported between the aggregation node and a core-network control plane entity; and sending, by the aggregation node, the non-access stratum message in the first format to the core-network control plane entity.

Abstract: Embodiments of the present disclosure disclose a method, an apparatus, and a system for data transmission. The method includes: broadcasting, by a relay device, a first message, where the first message is used to indicate that the relay device supports data forwarding; receiving, by the relay device, a second message from a remote device, where the second message includes data of the remote device; and sending, by the relay device, the data to a core network device based on the second message. In the present method, after receiving the first message broadcast by the relay device, the remote device directly sends the data of the remote device to the relay device without establishing a connection dedicated for transmitting the data of the remote device between the remote device and the relay device, thereby reducing signaling and reducing power consumption of the remote device.

Abstract: An embodiment of the present disclosure discloses a method and device for managing a forwarding plane tunnel resource. The method includes sending a forwarding plane tunnel resource request message to a forwarding plane device, for enabling the forwarding plane device to allocate a forwarding plane tunnel resource based on the forwarding plane tunnel resource request message; acquiring the allocated forwarding plane tunnel resource from the forwarding plane device; and sending the acquired forwarding plane tunnel resource to a target network element, to establish a packet data network connection with the target network element. By adopting the present disclosure, the load balancing of the forwarding plane device is achieved, the signaling interaction between the control plane device and the forwarding plane device is reduced.

Abstract: The present invention provides a packet processing method and an apparatus. The method includes: determining a to-be-installed flow entry and packet sending information; and sending, to a switch, a flow entry installation message carrying the to-be-installed flow entry and the packet sending information, so that the switch obtains the to-be-installed flow entry and the packet sending information from the flow entry installation message, installs the flow entry, and sends a packet according to the packet sending information. In the present invention, a controller sends a flow entry installation message carrying a to-be-installed flow entry and a packet sending message, where the to-be-installed flow entry and a to-be-sent packet are simultaneously sent, so that a switch simultaneously receives the to-be-installed flow entry and the to-be-sent packet, and performs flow entry installation and packet sending, thereby reducing unnecessary signaling exchange, and improving efficiency of flow entry installation and packet sending.
