Embodiment Construction

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0028] After research, the inventor found that in the prior art, the reason why the CPU load of the gateway network element is too large is that the gateway network element needs to serve as the application layer gateway function of the management and maintenance message, that is, the gateway network element receives the management and maintenance message. After the message is sent, the payload of the message must be parsed to identify the NE ID and then encapsulate...

Abstract

The invention discloses a DCN configuration method, a gateway network element and a data communication system. The gateway network element transmits a broadcast message having the IP address of a network management server to a non-gateway network element in a management area. The network element mark registration information transmitted by the non-gateway network element after the broadcast message is sent is acquired. A public network IP address and a private network IP address for device management are distributed by the non-gateway network element, and a NAT mapping table is formed and stored. The NAT mapping table is registered in the network management server. The message exchange between the non-gateway network element and the network management server can be achieved based on the NAT mapping table. When the message exchange is conducted between the network management server and the non-gateway network element, the gateway network element only needs to conduct a NAT conversion on the message. Accordingly, the CPU load of the gateway network element is reduced, the network element number in the management area is effectively increased and the forwarding efficiency of the message in the management area is improved.

Description

technical field [0001] The present invention relates to the technical field of communication, and more specifically, relates to a data communication network configuration method, a gateway network element and a data communication system. Background technique [0002] The backhaul bearer between the mobile base station and the wireless core equipment is carried by the fixed network equipment. In order to realize the remote deployment of the wireless backhaul, the existing technology adopts the data communication network (Data Communication Network, DCN) system to provide the network equipment with the communication function of management access and management control information, so that the network management server center can complete the communication of each Remote deployment and management of devices. [0003] A DCN system network is composed of a network management server, gateway network elements, non-gateway network elements and the connecting lines or networks betwe...
