Abstract

The invention provides a method and device for controlling updating of software of a dual-mode radio remote unit (RRU). In the method, the RRU is reset and sends channel establishment requests to two standard bandwidth based units (BBU), only the BBU for triggering the software to update is informed to check software version, and the BBU for not triggering the software to upgrade enables a software version check result cell to be arranged as conformity when channel establishment responses are sent. The method and device for updating and controlling the software of the dual-mode radio remote unit can avoid ping-pong phenomena caused by updating of the RRU software.

Description

technical field

[0001] The invention relates to mobile communication technology, in particular to a software update control method and device for a dual-mode radio frequency remote unit (RRU). Background technique

[0002] In the current mobile communication network, in order to support both TD-SCDMA and LTE networks, a dual-mode network is introduced. In the scenario of a dual-mode network, there are two standard baseband units (BBUs) at the base station, that is, a standard-A BBU and a standard-B BBU, which share a multi-mode RRU, and the RRU supports both systems at the same time.

[0003] In practical applications, TD-SCDMA and LTE networks will upgrade the software version on the RRU side independently according to their respective needs. According to the existing agreement, after the software upgrade on the RRU side, the RRU will reset. After the reset, the RRU will send a channel establishment request to each BBU. Whether the RRU software version information carried...
