Description

Method for configuring RRU device, RRU device, intermediate device, and computer storage medium

Technical field

The present invention relates to the field of communications, and in particular, to a method for configuring a radio remote unit (RRU) device, an RRU device, an intermediate device, and a computer storage medium.

Background technique

A wireless cellular system generally includes a core network and an access network. The access network part is currently 2G, 3G, 4G or 5G in the pre-research stage. The main deployment methods are the base station processing unit (BBU) and the RRU distributed base station.

Due to the increase in the construction and operation and maintenance costs of the computer room in recent years, the application mode of the industry has a tendency to place the BBU more and more concentrated. The concentration of BBU has spawned new concepts such as cloud base stations and baseband pools. Since BBUs are centralized, they need to share baseband resources and can smooth business fluctuations in different coverage areas. At the same time, due to the rapid development of wireless communication standards in recent years, most operators operate 2G, 3G and 4G wireless networks at the same time. For this application scenario, various wireless device vendors have introduced multi-mode BBU and RRU devices. The connection relationship of the radio access network part is more and more complicated.

Currently, the configuration data of the BBU and the RRU are configured on the U2000 and delivered to the BBU. The device type, the connection relationship between the devices, the service type running on the device, and the service parameters are fixed. .

If the device finds that there is any inconsistency with the configuration after startup, it will report the alarm and wait for the background personnel to change the configuration or reinstall it on site. In addition, if a port of the BBU device fails, or the RRU device is replaced with a different type of device, the data of the site needs to be reconfigured. As the baseband pool becomes larger, these configuration tasks will become more cumbersome.
