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 invention provides a data transmission device method and device. The method comprises the steps that when a first node receives a data packet for terminal UE, the second node of the next hop is selected according to routing information corresponding to the UE; the first node packages the data packet; and the first node sends the packaged data packet to the second node of the next hop. According to the invention, corresponding routing information is established for the UE; APs on a number of paths maintain the respective routing information table; in a data transmission process, the node carries out routing selection according to the routing information table of the self-maintained UE without routing through an IP; the packet header spending of the data packet is reduced; routing selection can be carried out through analysis at the bottom; an IP address is acquired without high-level parsing; and the data transmission efficiency is effectively improved.

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...
