Description
Technical field
The present invention relates to wireless communication technology field, relate in particular to a kind of method and device of controlling remote radio unit (RRU) RRU remote upgrade.
Background technology
In the wireless access network applied environment, the covering of radiofrequency signal is normally by BBU (Building Baseband Unit on a large scale, baseband processing unit) and RRU (Remote Radio Unit, remote radio unit (RRU)) jointly complete, between BBU and RRU, need to connect with optical fiber, its interface, based on Ir (Interface between the RRU and the BBU), is called the Ir interface, and a BBU can support a plurality of RRU.
The geographical position that RRU distributes disperses, and quantity is large.Riding position is usually all more special, as roof, tower top, subway tunnel etc., therefore is not suitable for adopting near-end upgrading mode to be upgraded to RRU.Be connected with BBU because RRU has data path, therefore generally, adopt the remote upgrade mode, by BBU, RRU is carried out to batch upgrade.
The RRU networking mode is along with the unification of the Ir interface diversification that becomes, it is inevitable that different manufacturers, different model mixed networking have also become, while by BBU, RRU being carried out to batch upgrade, not only need to tackle multiple RRU networking scenario as star-like, chain, ring-like, mixed type networking mode etc., need to tackle the Multiple Type of a plurality of producers, the RRU of multiple types simultaneously, also need to support software, the firmware upgrade carried out for defect repair and Function Extension.
Based on the Ir interface, by BBU, RRU is carried out to batch upgrade and mainly contains following two kinds of modes at present:
As shown in Figure 1, a pair of RRU upgrading of employing mode mainly comprises the following steps:
Step S101, determine that in the time of need to carrying out batch upgrade to RRU, management station issues AKU to BBU, controls BBU and reset, and wherein BBU resets and makes the RRU service disconnection;
Step S102, after the RRU service disconnection, when again accessing, BBU sets up configuration messages to the RRU sendaisle, and this Path Setup configuration messages carries the new software version that AKU is corresponding;
Step S103, RRU determines whether to be upgraded according to the new software version received, and when as consistent as new software version and RRU self software version, determine and does not need upgrading, again accesses and finishes; When inconsistent, determine and need upgrading, and execution step S104;
Step S104, RRU notice BBU when to the BBU sendaisle, setting up the configuration response message need to download AKU;
Step S105, BBU sends to AKU the RRU that needs to download AKU, as by FTP (File Transfer Protocol, file transfer protocol (FTP)), AKU sent to RRU after receiving above-mentioned Path Setup configuration response message;
Step S106, RRU downloads result by AKU and notifies to BBU, and BBU, after the message that receives the version failed download, can resend, if reach transmission times, can report to the police;
Step S107, RRU, after successfully downloading AKU, utilizes AKU to be upgraded (comprising software upgrading and firmware upgrade), after upgrading, obtains new software version, after upgrading successfully, resets, can not re-accessing network after upgrading unsuccessfully;
Step S108, the RRU new software version of the rear use access BBU that resets, access successful execution RRU business.
Adopt the RRU upgrade method of this mode mainly to have following problem:
1) time out of service is long
Wireless access network is the network of directly serving the user, should as much as possible increase the RRU business and take the time.And according to above-mentioned RRU upgrade method, after resetting, control BBU can make the RRU service disconnection, therefore download AKU and write the RRU non-volatile memory medium from BBU, after the RRU service disconnection, carry out, therefore the time out of service of RRU business comprises: download AKU time, update time and reset after turn-on time again, the time out of service of RRU business is long.
2) can't carry out flow control
Due to the RRU that does not adopt new software version mass simultaneous upgrading after BBU resets, therefore often there will be a plurality of RRU simultaneously from the BBU file that downloads, cause in the short time taking a large amount of bandwidth, affect network stabilization.
3) colony's flow process is considered
Because each RRU is separate the upgrading, when carrying out cascade network, if it is not new software version that RRU not at the same level finds software version after BBU resets, can carry out the AKU download simultaneously, and the RRU of general upper level can fulfil the AKU download ahead of schedule, therefore other RRU that upper level RRU compares following cascade can reset in advance, and resetting in advance of upper level RRU can cause the RRU short time of following cascade to communicate by letter with BBU.Therefore, can again to BBU, send request and download the AKU instruction, cause AKU to duplicate download, thereby affect Network.
4) can't effectively monitor escalation process
Because upgrading is to be triggered by the access process again of RRU, accessed after only having the RRU upgrading, just can learn and upgrade successfully, if fault after the RRU upgrading is difficult for statistics, therefore can't carry out escalation process monitoring targetedly.
The RRU upgrade method more application of aforesaid way is used when the software of batch replacement RRU, is unsuitable for pointedly indivedual RRU being upgraded.
As shown in Figure 2, two pairs of RRU upgradings of employing mode mainly comprise the following steps:
Step S201, BBU obtains the AKU for RRU is upgraded, and to the RRU transmission download request instruction of needs upgrading, this download request instruction carries the new software version that AKU is corresponding;
Step S202, after RRU receives the download request instruction, according to the new software version received, determine whether to be upgraded, and notify BBU by the download request response message by definite result, when new software version as corresponding as this AKU is consistent with RRU self software version, determine and do not need upgrading, as inconsistent, determine and need upgrading;
Step S203, the download request response message that BBU returns according to RRU is determined, when RRU need to upgrade, AKU is sent to this RRU;
Step S204, RRU receives the AKU that BBU issues, and returns to AKU and download result;
Step S205, the AKU that BBU returns according to RRU is downloaded result, while determining the RRU failed download, can return to step S203 and resend AKU to reaching maximum number of times of transmission, determines and issues the version activation request to RRU when RRU downloads successfully;
Step S206, after RRU receives the version activation request that BBU issues, interrupt the RRU business and utilize AKU to be upgraded, and access again resets after upgrading.
Because the upgrading RRU most of the time is during downloading from BBU and writing the RRU non-volatile memory medium, this part time and RRU business are carried out and are not conflicted, adopt above-mentioned RRU upgrade method, this step is advanced to and the business parallel processing, the time out of service of RRU business comprises like this: lower update time and reset after turn-on time again, can effectively reduce time out of service.
The above-mentioned mode of directly controlling the RRU upgrading by BBU, carry out for specific RRU while being generally used for the RRU troubleshooting.Although can effectively reduce time out of service, there is following shortcoming in this RRU upgrade method:
1) be not suitable for batch upgrade.
Because RRU downloads AKU from BBU, be to carry out in the business of execution, therefore, be not suitable for downloading AKU from BBU in large quantity, if use the method batch upgrade, can cause a plurality of RRU to download AKU from BBU simultaneously, be easy to occur that BBU causes greatly service exception because of flow;
2) colony's flow process is considered
When carrying out cascade network, there will be equally foregoingly because upper level RRU resets in advance, and the RRU of following cascade fails to activate new software version, causes the RRU short time of following cascade to communicate by letter with BBU.Therefore, can again to BBU, send request and download the AKU instruction, cause AKU to duplicate download, thereby affect Network.
3) can't be monitored escalation process equally.
