For making purpose of the present invention, technical scheme and advantage clearer, below with reference to the accompanying drawing preferred embodiment that develops simultaneously, the present invention is described in more detail.
Fig. 3 is the principle schematic that RRU realization of the present invention resets, and as can be seen from Figure 3, RRU mainly comprises with lower module:
Main control module: the operation and the state that are used for each module of control and management RRU, wherein, by the warm reset signal, control logic control module other all modules except that transport module among the RRU that reset, at this moment, main control module receives from the global reset signal of Logic control module and resets self; By the transport module reset command that sends to Logic control module, the control logic control module transport module among the RRU that resets.
Radio frequency power amplification modules: the wireless receiving and the sending function that are used to provide RRU.The resetting of radio frequency power amplification modules is subjected to the control of the global reset signal of Logic control module output.
Transport module: be used to provide between RRU and the base station and the transmission channel between RRU and the RRU, be used to transmit information such as data, clock.The resetting of transport module is subjected to the control of the transport module reset signal of Logic control module output.
Logic control module: be used to distinguish the reset command type of RRU, and produce different reset signals according to different reset commands, disparate modules resets among the control RRU.Be exactly specifically, when Logic control module receives from the hard reset order of reset button/reset switch or during from the warm reset order of main control module, Logic control module output global reset signal other all modules except that transport module among the RRU that reset, such as: the output global reset signal is given main control module and radio frequency power amplification modules, the control main control module, radio frequency power amplification modules and Logic control module reset separately self, here, will be collectively referred to as the Global reset order from the hard reset order of the button/reset switch that resets or from the warm reset order of main control module; When Logic control module receive from main control module or from network management center the transport module reset command time, Logic control module output transport module reset signal is given transport module, the transport module among the RRU that resets.
Above-mentioned hard reset order and provide by the attendant according to actual conditions from the transport module reset command of network management center, warm reset order and be respectively the main control module of RRU when detecting RRU and transport module and having fault from the transport module reset command of main control module, the reset command that sends.The method that produces reset command belongs to prior art, repeats no more here.What emphasize here is, resetting of transport module controlled separately, guarantees that transport module only under situation about self breaking down, just carries out reset operation.
Fig. 4 is the flow chart that RRU of the present invention resets, in conjunction with Fig. 3, between RRU1/ base station, RRU2 and the RRU3, realize chain networking communication by transport module separately, suppose that each RRU in the networking is in normal operating conditions, so, after the Logic control module among certain RRU was received reset command, the inventive method may further comprise the steps:
Logic control module is judged the type of the reset command that receives among the step 400:RRU, if the Global reset order then enters step 401; If the transport module reset command enters step 402.
In order to distinguish the type of different reset commands, the different input ports that Logic control module can be set receive different reset commands.Such as input port 0 corresponding hard reset order, input port 1 corresponding warm reset order, input port 2 correspondences are from the transport module reset command of main control module, and input port 3 correspondences are from transport module reset command of network management center etc.; Also can adopt the method for software to distinguish different reset commands.
Logic control module if detect reset command, then according to reset command place port, is determined the type of this reset command by the detection to different input ports.
Logic control module can adopt programmable logic device (EPLD), CPLD (CPLD), field programmable gate array (FPGA) chip to wait and realize.
In this step, the Global reset order comprises the warm reset order of sending by the hard reset order of reset button input and main control module etc.; The transport module reset command can be from main control module, or network management center.Among the present invention, whether Logic control module can real-time detection receive reset command.
By of the differentiation of this step to different reset commands, realized the control that resets separately to transport module among the RRU, guaranteed that under the situation that other module resets among the RRU, transport module still can normally provide communication.
Step 401: Logic control module output global reset signal, all modules among the RRU that resets except that transport module are returned step 400 afterwards.
From this step as can be seen, global reset signal main control module, radio frequency power amplification modules and the Logic control module self among the RRU that only reset, transport module still is in normal operating conditions, can continue normally to provide communication, thereby guarantees the proper communication of back level RRU and prime RRU.
Step 402: Logic control module output transport module reset signal, the transport module among the RRU that resets returns step 400 afterwards.
In step 401 and the step 402, different reset signals is by the different output port outputs of Logic control module, thereby disparate modules resets among the control RRU.
The above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.
