Embodiment Construction

[0021] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0022] The core idea of ​​the present invention is: when the RRU is reset and sends channel establishment requests to the BBUs of the two standards, only the BBU that triggers the software upgrade is notified to check the software version, and the BBU that does not trigger the software upgrade sends the channel establishment response The software version checking result cell of the channel is set to "consistent version", so that the RRU will not be triggered to update the software due to the inconsistency of the checking result carried in the channel establishment response, thereby avoiding the ping-pong phenomenon of the RRU software update. At the same time, due to High-level communication between the two standard BBUs is not required, s...

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...
