Whether step S810, user select to upgrade, if upgrading then select upgraded version in memory is coordinated other functional module by control module, carry out version and upload.
Step S812, version upload and finish, and the user can pass through the eRRU management devices, send order and activate version.
Step S814, the eRRU edition upgrading activates and finishes, and disconnection of eRRU management devices and eRRU are connected, and finish management.
Step S816, the control module of eRRU sends edition upgrading information notice eBBU, the version information of eBBU database synchronization eRRU.
Present embodiment has been realized eRRU is carried out the edition upgrading operation, has reduced O﹠M cost.
Fig. 9 is according to the flow chart of the light mouth fault solution of the embodiment of the invention, as shown in Figure 9, comprising:
Step S902, eBBU are connected disconnection with eRRU, alarm appears in the light mouth.This moment, control module switched to eRRU the radio management pattern.
Step S904 sets up wireless connections by secured fashion.
Whether step S906 carries out the loopback test order to the eRRU transmission to the light mouth, test its related software system and move normally.
Step S908, eRRU sends test result to the eRRU management devices by down going channel.
Step S910, the diagnostic module of eRRU management devices is analyzed the result, and according to failure strategy storehouse output function reply, according to the operation reply, eRRU is managed.
For example: when the FPGA version operation exception that detects eRRU, can advise restarting the FPGA version, and suggestion is presented on the control panel, the operator can send reset command according to suggestion, also can not carry out this suggestion operations, withdraw from the suggestion page, carry out other operation or the like.
Step S912 if fault solves, disconnects connection, finishes management.
Step S914, eRRU sends to eBBU with debugging log, and synchronizing information, light mouth fault solve and finish.
Realized in the present embodiment that to the troubleshooting of eRRU light mouth similarly, if eRRU and eBBU employing is the cable connected mode, the processing mode that the cable connection is broken down is identical with the method for present embodiment.
Need to prove, can in computer system, carry out in the step shown in the flow chart of accompanying drawing such as a set of computer-executable instructions, and, though there is shown logical order in flow process, but in some cases, can carry out step shown or that describe with the order that is different from herein.Need to prove that this method and device can be applied to the on-the-spot beginning debugging of engineering staff, website regular maintenance and development and testing personnel and transfer occasions such as survey.
The present invention carries out the management devices of remote servicing, configuration and failure diagnosis to eRRU by wireless connections.But automatic or manual switch mode (radio management pattern/normal mode of operation), the operate as normal to former eRRU does not constitute influence like this, can save the power consumption of eRRU simultaneously again; By easy operation, adopt the generation strategy reply of failure strategy storehouse, assist the engineering staff to safeguard eRRU, reduce human intervention, improved to transfer and surveyed efficient, reduced O﹠M cost.
