Step 605: judge that the upper strata starts software and loads success? If then carry out step 606; Otherwise, carry out step 611, at this moment, RRU will get into debugging mode, launch the basis and start software and carry out fault and report.
Step 606: after the upper strata started the software loading success, whether the optical fiber link that RRU detects between this locality and the BBU successful synchronously? If then carry out step 607; Otherwise, carry out step 610.
Step 607:RRU obtains RRU ID, obtains the IP address from BBU, and foundation is connected with TCP/IP between the BBU.
Be specially: RRU detect between this locality and the BBU optical fiber link synchronously after; Obtain the RRU ID that BBU issues, obtain successfully after, RRU sends the broadcasting carry the self MAC address to BBU and sets up request message; BBU receives that back transmission broadcast request response message is to RRU; Carrying BBU in this broadcast request response message is each the RRU IP address allocated in the link, the corresponding RRUID in each IP address, and all RRU on the link are according to the RRU ID of self; In the broadcast request response message that receives, intercept and capture the one's own IP address that BBU distributes, and the IP address of BBU; And the IP address of IP address that is assigned to according to self and BBU, set up the TCP/IP link between RRU and the BBU.
After definite TCP/IP link establishment success, RRU begins to set up request message to the BBU sendaisle, and continues to implement to meet the access process of Ir protocol specification, repeats no more at this.
Does step 608:RRU judge that the TCP/IP link between this locality and the BBU sets up success? If then execution in step 609; Otherwise, execution in step 611.
Step 609:RRU sets up request to the BBU sendaisle, begins to get into normal access process.
Step 610:RRU judges whether operate as normal of corresponding light mouth under the situation of optical fiber link synchronization failure, promptly whether the transmitting-receiving luminous power of light mouth normal? If then carry out step 611; Otherwise, carry out step 604.
Step 611:RRU starts software through the basis that local BSP program loads the assigned address storage.
In the present embodiment; The basis of the last operation of RRU starts software; Preferable; Should comprise SI file, HL file and the FPGA file simplified according to predetermined manner, be used to accomplish functions such as basic optical fiber link is synchronous, TCP/IP foundation, FTP (File Transfer Protocol, FTP) download; Further, start the fail safe of software, prevent it and lose or error in data occurs in order to guarantee the basis, preferable, the basis is started the designated storage location of software predetermined fixed programming in RRU.
Did step 612: after the basis started the software loading success, RRU judge whether the optical fiber link between this locality and the BBU successful synchronously? If then carry out step 613; Otherwise, carry out step 618.
Step 613:RRU sets up the TCP/IP link between this locality and the BBU.
Be specially: RRU sends the broadcasting of carrying the self MAC address to BBU and sets up request message; BBU receives that back transmission broadcast request response message is to RRU; Carrying BBU in this broadcast request response message is each the RRU IP address allocated in the link, the corresponding MAC Address in each IP address, and all RRU on the link are according to the MAC Address of self; In the broadcast request response message that receives, intercept and capture the one's own IP address that BBU distributes, and the IP address of BBU; And the IP address of IP address that is assigned to according to self and BBU, set up the TCP/IP link between RRU and the BBU.
After getting into debugging mode; RRU may obtain the RRU ID that issues less than BBU owing to the link failure reason, and is therefore, preferable; In the present embodiment; RRU mails to BBU with the MAC Address of this locality, makes BBU distribute based on this MAC Address and issues corresponding IP address, to guarantee that RRU can get access to this IP address.
Certainly, if RRU can get access to the RRU ID that BBU issues, then also can be according to the mode of step 607 record, the RRU ID that obtains through this locality obtains the BBU IP address allocated, repeats no more at this.
Further, RRU also can adopt the identification information that other can unique identification RRU to obtain the BBU IP address allocated, does not describe one by one at this.
Does step 614:RRU judge that the TCP/IP link between this locality and the BBU sets up success? If then execution in step 615; Otherwise, execution in step 618.
Step 615:RRU adopts self-defining Indication message based on the TCP/IP link of having set up, and to the BBU notice, RRU breaks down, and has switched to debugging mode.
Step 616:BBU lands the RRU controlling platform and carries out troubleshooting after receiving the Indication message of RRU transmission.
If RRU does not have fault location function, after then BBU receives above-mentioned Indication message, it is presented to administrative staff; Administrative staff need be through BBU login RRU control desk; Carry out fault location, debugging, confirming the not reason of operate as normal of RRU, and provide correct fault solution through BBU; For example; When definite RRU is that RRU starts software from the upper strata that the BBU side is downloaded latest edition through the BBU indication because the upper strata starts that software disappearance, upper strata start that software version does not match or upper strata when starting software and being destroyed or the like all kinds of reasons and causing cisco unity malfunction, and after downloading successfully, switches to normal mode and restart; As, after downloading completion, can send self-defining mode switch message to RRU through BBU, make RRU switch to normal mode, the new normal access process of initiating of laying equal stress on.
If RRU has fault location function, after then BBU receives above-mentioned Indication message, it is presented to administrative staff; Administrative staff directly provide correct fault solution through BBU, for example, are because the upper strata starts that software disappearance, upper strata start that software version does not match or upper strata when starting software and being destroyed or the like all kinds of reasons and causing cisco unity malfunction when RRU confirms this locality; Notice BBU; Administrative staff start software through BBU indication RRU from the upper strata that the BBU side is downloaded latest edition, and after downloading successfully, switch to normal mode and restart, as; After downloading completion; Can send self-defining mode switch message to RRU through BBU, make RRU switch to normal mode, the new normal access process of initiating of laying equal stress on.
Does step 617:RRU judge whether this earth fault solves? If then return step 601; Otherwise, carry out step 618.
For example, after RRU judges that local upper strata of downloading latest edition starts software, can successful switch to normal mode? If then return step 601 and start software according to the upper strata of latest edition and restart; Otherwise, get into step 618.
Step 618; RRU confirms the access process execution failure of startup, rests on debugging mode, and the wait manual intervention is handled.
At this moment, RRU starts the access process failure under debugging mode, then can only rest on this stage, waits for artificial to the preliminary treatment of RRU proximal stem.
In sum; In the embodiment of the invention; Between the BBU of TD-SCDMA base station system and RRU, adopted a kind of fault handling method of design again; Be specially: thus when between BBU and the RRU because certain fault is set up after failure causes RRU to insert normal Ir passage, RRU can have cured the basis of programming in RRU through automatic loading and start software, between this locality and BBU, attempts setting up automatically special operational maintaining channel; Make the Operation and Maintenance control desk that BBU can long-range connection RRU, and then in time the RRU that breaks down is carried out fault location and fault eliminating.Like this, can improve the fault removal efficiency of RRU effectively, reduce the O&M cost of RRU, thus promoted greatly RRU in the net time, and then guaranteed effectively the stability of system to have ensured systematic function.
