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

A kind of microwave outdoor unit remote upgrade method

Technical field

The present invention relates in microwave transmission system, one kind passes through indoor unit（IDU）To outdoor unit（ODU）Software upgrading Method, and in particular to a kind of microwave outdoor unit remote upgrade method.

Background technology

In microwave transmission system, indoor unit is generally divided into（IDU）And outdoor unit（ODU）, outdoor unit is placed on base Stand on steel tower, generally more than 30 meters of height, IDU is connected with ODU by IF cable, and network management monitoring information is also by this link Transmission.When ODU breaks down or ODU function renewals need ROMPaq, by the close ODU of upper tower come upgrade maintenance very not It is convenient, for this purpose, a kind of method to ODU remote upgrades that the present invention is introduced, can very easily give ODU in machine room by IDU Carry out software upgrade job, the convenient function upgrading for ODU.

The content of the invention

To solve the problems, such as background technology, the invention provides a kind of microwave outdoor unit remote upgrade method, bag Include following steps：

Step（1）, IDU identification ODU software versions need upgrading, IDU and ODU begins setting up stabilized communication and links, and IDU is opened Begin upgrading flow process；

Step（2）, IDU split ODU software upgrade packages, start to ODU send monitoring software AKU, in escalation process Interaction confirms to be verified using often bag, often bag validation testing；

Step（3）, ODU carry out software efficiency verification, back up original program, switch new procedures.

Step（1）Described in IDU identification ODU software versions need upgrading, IDU and ODU begins setting up stabilized communication and links, IDU starts flow process of upgrading, and further includes herein below：

When IDU is received to the control instruction of ODU upgradings, and IDU is detected in the current software version and IDU of ODU During the ODU non-uniformity of software versions of storage, IDU sends test data bag test and ODU communication link stability, if communicated into Power is more than 95%, then prepare to send software upgrade package to ODU（Step 104）, prepare to give ODU upgrading softwares（Step 101, 102）；

2. IDU detect ODU current software version it is consistent with the ODU software versions of IDU memory storages when, IDU stop rise Level flow process（Step 103）.

Step（2）Described in IDU split ODU software upgrade packages, start to send monitoring software AKU to ODU, and realize Interaction confirmation in escalation process, further includes herein below：

IDU sends the essential information of software upgrade package, including the fileinfo of ODU AKUs, upgrading data packet to ODU Check code, AKU size, AKU split after each packet magnitude of load（Step 105）；

2. ODU is received after the essential information of the software upgrade package of IDU transmissions, checks the fileinfo of AKU；If Fileinfo is legal, and ODU starts software upgrade package and receives flow process, notifies that IDU prepares the transmission of upgrading data packet（Step 107）； If fileinfo is illegal, ODU stops upgrading, notifies that IDU files are illegal, stops upgrading flow process（Step 106）；

3. IDU is received after the information after ODU prepares, and sends packet successively in order（Step 111）；

If 4. ODU receives serial number data bag check code mismatch, notify that IDU resends certain serial number data bag（Step Rapid 112, step 113, step 114）；

If 5. ODU receives packet sequence number and mismatches with AKU transmission order, notify that IDU sends appointed sequence number number According to bag（Step 115, step 116, step 117）；

If 6. ODU when next time upgrades again, notifies IDU from last time because abnormal end is upgraded in escalation process Disconnected sequence number starts upgrading（Step 108, step 109, step 110）.

Step（3）Described in ODU carry out software efficiency verification, back up original program, switch new procedures, further include with Lower content：

1. ODU is received after the completion of AKU, and it has received all packets to notify IDU（Step 118）；

ODU is integrated to all upgrading data packets by sequence number, and calculates check code, if when check code starts with upgrading Information is consistent, notifies that IDU AKUs are properly received and finishes；Otherwise notify that IDU upgrade files preserve failure, upgrading needs again Start（Step 118, step 119, step 120, step 121）；

After the verification success of ODU AKUs, original program is backed up, preparation is switched to new procedures；

ODU runs new procedures, if ODU to start new procedures unsuccessful, automatically switch to original program operation, and to IDU Report ODU updating results（Step 122, step 123, step 124）.

Compared with prior art, it is an advantage of the invention that：

1. upgraded to ODU softwares by IDU, it is possible to achieve efficient to ODU, safe upgrading；

2. escalation process whole process is controllable, using often bag verification, often bag validation testing, it is ensured that upgrading reliability；

3. breaker point continuous transmission method is employed, if communication link breaks down, ODU can preserve last time IDU and send over Successful packet information, as the starting point of next same upgrade file, improve and rise a stage efficiency；

4. the new early version backup of ODU programs, if exception occurs in new ROMPaq, can revert to legacy code operation, protect The security of card software upgrading.
