Embodiment Construction

[0024] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0025] figure 1 A system architecture of a multi-relay wireless communication network according to an embodiment of the present invention is shown. The backbone of the entire wireless communication network system is composed of multiple relay nodes arranged in a specific topology, and the relay nodes are also called relay communication nodes (RCN for short). During network communication, data is forwarded sequentially between network nodes, forming a multi-hop path. The network topology is formed when the physical connection is established between the relay nodes, and the network topology assigns a value generated in increasing order to the RCN joining the network according to the direction of topology expansion as the node ID (identific...

Abstract

The invention discloses a multi-relay wireless communication system and a method for realizing IP (Internet Protocol)-based air interface for the same. The method comprises the following steps of: allocating node identifier information for each relay node, and obtaining a private IP address of each relay node according to the node identifier information of each relay node; and performing PPP (Peer-Peer Protocol) link negotiation according to the private IP address of the relay node, building an IP communication link between the two neighboring relay nodes, and performing data communication through the built IP communication links. The method realizes the TCP / IP (Transmission Control Protocol / Internet Protocol)-based network data transmission of the air interface, really realizes the protocol standardization, bears various wireless data services by IPs and performs the multi-hop transmission, avoids the inter-protocol conversion and reduces the system overhead.

Description

technical field [0001] The invention relates to the communication field, in particular to a multi-relay wireless communication system and a method for realizing IP-based air interface of the system. Background technique [0002] With the attention of Internet of Things technology, wireless communication technology has also developed rapidly. Wireless communication technology and its applications have become one of the most active research fields in information science and technology today. Among them, the public network transmission technology represented by GSM\CDMA, 3G, LTE, etc., and the private network transmission technology represented by WiMAX, WiFi Mesh, etc. are the most popular wireless communication technology applications. [0003] From the perspective of network topology, the existing wireless communication technologies are mostly point-to-multipoint star or mesh structures. These technologies can meet the needs of regional coverage. There are certain deficien...
