Background

In recent years, with the rapid development of wireless communication technology, a large number of communication devices are applied to each communication system, and devices such as a base station, a wireless repeater, a fiber repeater and the like are distributed to each position which needs signal coverage, and due to the large number and wide distribution, for the operation conditions of the devices, a device operator needs to know the real-time operation condition, and a device manufacturer needs to know the field operation condition to perform some remote device maintenance, so that it is necessary to provide a management system for centrally managing the devices distributed in various places, and for the management of the devices, the common practice in the communication field is roughly divided into several types: firstly, the SNMP protocol is utilized for remote management, the scheme is mainly applied to early products, the operation needs to be managed by special SNMP supporting software, secondly, a special management protocol is developed, all equipment is monitored in a centralized mode, and the method is relatively universal at present.

In the above two schemes, only some basic application layer information is provided, which is required for an operator to know some basic device operation conditions, but once the device is abnormally operated, the operator can only be informed to perform fault removal, the device manufacturer can maintain the device fault on the operation field, usually except for remote upgrade, the operator goes to the device field to perform field maintenance, however, the environment of the device field is very bad, and the device is very difficult to operate, but the abnormal operation state of many devices can only be captured on the field, sometimes, the operator needs to last for a long time in order to capture the abnormal operation LOG on the field, thus, time and energy are wasted, and the efficiency is low.

And S2, after the CAU system is started, dialing is carried out through the built-in wireless module, and the INTERNET is connected.

And S3, when the dialing is successful, the virtual private network module starts to send a virtual service request to the ISP intermediate service provider.

S4, after ISP intermediate service provider receives the network request of virtual private network user, it distributes IP address (such as 10.0.0.8) of each virtual private network to CAU according to the account number of requirement.

S5, the CAU receives the IP address (10.0.0.8) assigned by the ISP to complete the networking of the northbound interface.

S6, when the user wants to access the CAU, the user can get another virtual private network IP address (10.12.168.10) through the PC which can be connected with the network, the VPN dialing program and the account number provided by the ISP intermediate service provider, wherein the interconnection of the IP address and the CAU IP address is provided by the ISP service provider.

Second, the near-end unit is interconnected with the far-end unit
