Problems solved by technology

[0006] However, this method of transferring through the BBU has two defects: the BBU under the network management system needs to download and store the upgrade package regardless of whether it involves related upgrades, which often brings an additional storage burden to the BBU, resulting in an increase in the BBU cost. ;Secondly, it will also bring a lot of extra network data to the network, increasing the load of the network

Embodiment 1

[0035] figure 2 Shows a step diagram of the method of the present invention, including:

[0036] A method for upgrading distributed small base stations includes the following steps:

[0037] Step 1: Upgrade the management equipment to deploy a new software upgrade package;

[0038] The upgrade management device is responsible for managing the deployment of all RRU upgrade packages. The upgrade packages of different RRU equipment manufacturers are not the same, so they need to be arranged separately.

[0039] Step 2: The upgrade management device encapsulates the version number, manufacturer ID, and mandatory upgrade ID of the upgrade package into an upgrade prompt message;

[0040] The version number is an important identification of the software, which can facilitate the viewing and identification of the current state of the software, and is a necessary content for the management of the software. The upgrade packages of different manufacturers are not inconsistent. In order to distin...

[0061] image 3 Shows a structural block diagram of the system of the present invention, including:

[0062] A distributed small base station upgrade system, including: upgrade management equipment, baseband unit BBU, radio remote unit RRU:

[0063] The upgrade management device includes a deployment unit: for deploying a new software upgrade package, and encapsulating the version number, manufacturer ID, and mandatory upgrade ID of the upgrade package into an upgrade prompt message to broadcast to the subordinate BBU; the issuing unit: for After receiving the upgrade request message, make a differential upgrade package according to the version number of the RRU, and then send it to the corresponding BBU in the upgrade request message;

[0064] The upgrade management device is responsible for managing the deployment of all RRU upgrade packages. The upgrade packages of different RRU equipment manufacturers are not the same, so they need to be arranged separately.

Abstract

The invention discloses an upgrading method and system of a distributed small base station. During upgrade of planed deployment base station software, upgrade packages are identified and distinguishedthrough version numbers, manufacturer identifications, and forced upgrade so that the upgrade efficiency is improved. Before an upgrade operation of an RRU, transmission and reception upgrade promptmessages are only adopted among upgrade management equipment, a BBU and the RRU, and repeated downloading of the upgrade packages is avoided; besides, after confirmation of upgrade, only a differential package is downloaded so that the network burden is alleviated.

Description

Technical field [0001] The present invention relates to the field of wireless communication technology, in particular to a method and system for remote upgrade of small base stations. Background technique [0002] With the rapid development of the mobile Internet, data traffic has maintained a rapid growth trend in recent years. [0003] The network brings greater pressure. According to analysis, more than 60% of 4G network services occur indoors, and it is expected that the proportion of indoor services in the 5G network era will further increase in the future. Possible construction plans for indoor signal coverage include outdoor coverage indoor methods, traditional DAS systems, indoor fiber distribution systems, and distributed small base stations. [0004] Among them, in terms of distributed small base stations, the existing 4G distributed small base stations can support 5G NR through transformation methods, using CAT6A network cables or live optical cables, which is relatively...
