Method and device for establishing routing table

Abstract

The invention discloses a method and device for establishing a routing table, comprising: a first AP generates a routing information table corresponding to the UE according to the access of a user equipment UE; the first AP reports the routing information corresponding to the UE to the first AP previous hop The node of the previous hop is another AP or a macro station. Through the solution of the present invention, when the UE accesses the wireless access point, the wireless access point is triggered to establish a routing information table based on the AP information of the wireless access point and the UE ID, and the APs on multiple paths maintain their own routes respectively. Information table, in the process of data transmission, the node performs routing selection according to the routing information table maintained by itself, without routing through IP, reducing the packet header overhead of the data packet, and routing can be selected through the analysis of the bottom layer, without the need to go through the upper layer. The IP address is obtained by 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 method and device for establishing a routing table. 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 ca...

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
