Problems solved by technology

[0008] In multi-hop communication, the complexity of the network increases, how to route the data of the previous hop to the next hop, the routing mechanism based on IP is currently used more often, and the routing mechanism based on IP will bring a large packet header overhead, which needs to be analyzed The IP address can only be obtained at the upper level, and the data analysis efficiency is low

Embodiment Construction

[0058] In order to facilitate the understanding of those skilled in the art, the present invention will be further described below in conjunction with the accompanying drawings, which cannot be used to limit the protection scope of the present invention. It should be noted that, in the case of no conflict, the embodiments in the present application and various manners in the embodiments can be combined with each other.

[0059] see figure 1 , the present invention proposes a data transmission method, the method comprising:

[0060] Step 110, when the first node receives the data packet for the UE, select the second node of the next hop according to the routing information corresponding to the UE;

[0061] Step 120, the first node encapsulates the data packet;

[0062] Step 130, the first node sends the encapsulated data packet to the next-hop second node.

[0063] In step 110, the data packet for the UE refers to a data packet to be sent to the UE or a data packet sent from...

Abstract

The present invention provides a method and device for a data transmission device. The method includes: when a first node receives a data packet for a terminal UE, selecting a second node of the next hop according to routing information corresponding to the UE; The data packet is encapsulated; the first node sends the encapsulated data packet to the second node of the next hop. Through the solution of the present invention, through the solution of the present invention, the corresponding routing information is established for the UE, and the APs on multiple paths maintain their own routing information tables respectively. During the data transmission process, the node maintains the routing information of the UE according to itself. Routing through the table does not need to be routed through IP, which reduces the header overhead of the data packet. The routing can be selected through the underlying parsing, and the IP address does not need to be obtained through the high-level parsing, thus effectively improving the efficiency of data transmission.

Description

technical field [0001] The invention relates to the field of data communication, in particular to a data transmission device method and device. Background technique [0002] In the wireless communication system, the ultra-dense network UDN (Ultra Dense Network) is one of the core technologies of 5G. Through the large-scale deployment of wireless access points, the access distance of users can be greatly reduced, thereby improving user throughput and regional coverage. Throughput (bps / km2) is a key technology to meet the capacity requirements of 5G systems. [0003] For wireless access points, since its main purpose is to meet the needs of high-traffic coverage, there are certain problems in ultra-dense networking scenarios where wireless nodes access macro stations through a one-hop wireless path: [0004] First of all, macro stations generally work at low frequency points to provide wide-area coverage, and the bandwidth of macro stations is not very large, which cannot mee...
