Problems solved by technology

[0004] According to the existing IR (Open Interface between the RRU and the BBU, the interface between the open BBU and the RRU) standard protocol, in order to achieve the above purpose, it is necessary to configure the message through the RRU parameter, that is, reconfigure the IQ data channel resources, delete this The IQ data channel resources occupied by the standard, but the IQ data channel resources occupied by other standards are reserved, and a combination of one or more cell configuration messages (cell deletion) is used to achieve the above purpose. When multiple carriers of the wireless standard are established on the RRU , to construct the above message combination, the implementation is more complicated

Embodiment Construction

[0063] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0064] refer to figure 1 , figure 2 , propose an embodiment of the method for releasing RRU resources by the IR interface of the present invention,

[0065] image 3 It is an example of resource allocation on the BBU and RRU under normal conditions. This embodiment includes two preferred implementation modes, which are not limited to the above two preferred implementation modes in practical application, and other implementation modes that can be considered by those skilled in the art are also applicable:

[0066] Method 1: No confirmation of the IR resource release request message, the processing steps are as follows:

[0067] A wireless standard control entity of the BBU, such as the TD-SCDMA standard control entity, detects an abnormality and decides to release the existing TD-SCDMA resources on the RRU; or th...

Abstract

The invention discloses a method, a device and a system for an IR (Interface between the RRU and the BBU) interface to release RRU (Radio Remote Unit) resources. The method comprises the steps that a BBU (Base Band Unit) transmits a resource release request message to the RRU; the resource release request message carries a wireless type to be released; and the RRU releases resources of the wireless type according to the resource release request message. According to the method, the device and the system for the IR (Interface between the RRU and the BBU) interface to release RRU (Radio Remote Unit) resources provided by the invention, a simple method for releasing RRU resources is provided, namely the existing IR industrial standard protocols are extended and the IR resource release request message is added.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, device and system for releasing RRU resources by an IR interface. Background technique [0002] At present, with the TDD (Time Division Duplexing, Time Division Duplex) LTE (Long Term Evolution, Long Term Evolution) standard and TD-SCDMA (Time Division-Synchronous Code Division Multiple Access, Time Division Synchronous Code Division Multiple Access) standard wireless frequency band resource planning, A dual-mode RRU (Radio Remote Unit, remote radio module) supporting both TDD LTE and TD-SCDMA has emerged. There are many forms of dual-mode RRU, or support multiple frequency bands, different frequency bands support different wireless standards, or support a frequency band, this frequency band can support both TDD LTE standard and TS-SCDMA standard, and this frequency band may also be Broadband frequency band, LTE carrier and TD-SCDMA carrier can exist at the same time,...
