Abstract
The invention relates to a remote microwave outdoor unit upgrading method which comprises the following steps: (1) identifying whether software version of an outdoor unit (ODU) needs to be upgraded through an indoor unit (IDU), establishing stable communication link between IDU and ODU, and starting the upgrading process through the IDU; (2) splitting the ODU software upgrade package through the IDU, starting to transmit monitoring software upgrade package to ODU, and realizing interaction confirmation in the upgrading process; and (3) performing the software validity check through the ODU, backing up the original program, and switching a new program. The upgrading method has the characteristics of high upgrading efficiency and the capacity of reducing the upgrading cost and upgrading difficulty, the whole software upgrading process is controllable and the upgrading success rate is improved due to the check and breakpoint transmission function of each package in the upgrading function, effective management of the version is realized, the original version operation can be realized under abnormal conditions, and the safety and reliability of the upgrading function are ensured. The ODU is generally mounted on an iron tower with the height of 30m, and when function upgrading is involved, the upgraded software of the ODU can be safely and reliably provided by using the method.
Description
Technical field
The present invention relates in microwave transmission system, a kind of method of giving outdoor unit (ODU) software upgrading by indoor unit (IDU), is specifically related to a kind of microwave outdoor unit remote upgrade method.
Background technology
In microwave transmission system, be generally divided into indoor unit (IDU) and outdoor unit (ODU), outdoor unit is placed on base station iron tower, is highly generally more than 30 meters, and IDU is connected by IF cable with ODU, and network management monitoring information is also by this link transmission.When ODU breaks down or when ODU function renewal needs ROMPaq, by upper tower, approaching ODU comes upgrade maintenance very inconvenient, for this reason, a kind of method of giving ODU remote upgrade that the present invention introduces, can by IDU, carry out software upgrade job very easily to ODU at machine room, convenient is the function upgrading of ODU.
Summary of the invention
The problem existing for solving background technology, the invention provides a kind of microwave outdoor unit remote upgrade method, comprises the following steps:
Step (1), IDU identification ODU software version need upgrading, and IDU starts to set up stabilized communication with ODU and links, and IDU starts the flow process of upgrading;
Step (2), IDU split ODU software upgrade package, start to send monitoring software AKU to ODU, and the mutual confirmation in escalation process adopts every bag verification, and every bag is confirmed mode;
Step (3), ODU carry out software efficiency verification, and backup original program, switches new procedures.
The identification of IDU described in step (1) ODU software version needs upgrading, and IDU starts to set up stabilized communication with ODU and links, and IDU starts the flow process of upgrading, and further comprises following content:
when IDU receives the steering order to ODU upgrading, and when IDU detects the current software version of ODU and the ODU non-uniformity of software versions of the interior storage of IDU, IDU sends test packet test and ODU communication link stability, if communication success ratio is greater than 95%, prepare to send software upgrade package (step 104) to ODU, prepare to ODU upgrade software (step 101,102);
2. IDU detects the ODU software version of storage in the current software version of ODU and IDU when consistent, the IDU flow process (step 103) that stops upgrading.
IDU described in step (2) splits ODU software upgrade package, starts to send monitoring software AKU to ODU, and realizes the mutual confirmation in escalation process, further comprises following content:
iDU sends the essential information of software upgrade package to ODU, comprise the fileinfo of ODU AKU, the check code of upgrading data packet, AKU size, the magnitude of load (step 105) of each packet after AKU splits;
2. ODU receives after the essential information of the software upgrade package that IDU sends, and checks the fileinfo of AKU; If fileinfo is legal, ODU starts software upgrade package and receives flow process, the transmission (step 107) that notice IDU prepares upgrading data packet; If fileinfo is illegal, ODU stops upgrading, and notice IDU file is illegal, and flow process (step 106) stops upgrading;
3. IDU receives after the information after ODU prepares, and sends successively in order packet (step 111);
If 4. ODU receives sequence number packet check code and do not mate, notice IDU resends certain sequence number packet (step 112, step 113, step 114);
If 5. ODU receives packet sequence number and do not mate with AKU sending order, notice IDU sends appointed sequence number packet (step 115, step 116, step 117);
If 6. ODU is due to abnormal end upgrading in escalation process, next time, while again upgrading, notice IDU was since the sequence number upgrading (step 108, step 109, step 110) of interruption last time.
Described in step (3), ODU carries out software efficiency verification, and backup original program, switches new procedures, further comprises following content:
1., after ODU reception AKU completes, it has received all packets (step 118) notice IDU;
oDU integrates by sequence number all upgrading data packet, and calculation check code, if information when check code starts with upgrading is consistent, notice IDU AKU successfully receives; Otherwise notice IDU upgrade file is preserved unsuccessfully, and upgrading need to restart (step 118, step 119, step 120, step 121);
after ODU AKU verification succeeds, by original program backup, prepare to be switched to new procedures;
oDU moves new procedures, unsuccessful if ODU starts new procedures, automatically switches to original program operation, and reports ODU updating result (step 122, step 123, step 124) to IDU.
Compared with prior art, advantage of the present invention is:
1. by IDU, to ODU software, upgrade, can realize efficient, the safe upgrading to ODU;
2. escalation process whole process is controlled, adopts every bag verification, every bag to confirm mode, guarantees the reliability of upgrading;
3. adopted breaker point continuous transmission method, if communication link breaks down, ODU can preserve the successful packet information that last time, IDU sended over, and as the starting point of same upgrade file next time, improves upgrading efficiency;
4. the new early version backup of ODU program, abnormal if new ROMPaq occurs, can revert to legacy code operation, guarantee the security of software upgrading.
