Embodiment Construction

[0031] The core idea of ​​the present invention is: add transmission module reset command in the main control module of network management center and RRU respectively, distinguish various RRU reset command types through the logical control module of setting, separately control the reset of transmission module in RRU, in When the logic control module receives a hard reset or soft reset command, the logic control module resets all modules in the RRU except the transmission module; when the logic control module receives a transmission module reset command, the logic control module resets the transmission module in the RRU.

[0032] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and preferred embodiments.

[0033] image 3 is a schematic diagram of the principle of RRU reset in the present invention, from image 3 It can be ...

Abstract

The method includes following steps: adding reset command of transmission module to network management center and main control module of RRU respectively; using logic control module set up distinguishes each type of RRU reset command to control reset of transmission module in RRU respectively; when receiving hard reset or soft reset command, logic control module resets all other modules except transmission module in RRU; when receiving reset command for transmission module, logic control module resets transmission module in RRU. The invention discloses method and system for realizing RRU reset. Advantages are: reducing cost of RRU, and ensuring reliability of system.

Description

technical field [0001] The invention relates to a wireless base station system, in particular to a method and system for resetting a radio remote unit (RRU, RadioRemote Unit) in the base station system. Background technique [0002] In a wireless communication network, the wireless base station system can be a base station including a radio frequency module; it can also be a distributed base station in which the base station and the radio frequency module are separated. For a distributed base station, the separated radio frequency remote module is called RRU. Various forms of networking can be performed between RRUs, such as: star, chain, tree, etc. The wireless access network provides users with wireless access functions. A base station or RRU can cover a certain area and provide services for users in the covered area. RRUs at all levels are connected through transmission modules to realize communication with the base station. Figure 1a It is a schematic diagram of the cha...
