In the existing technical scheme, a kind of simple proposal is arranged, this technical scheme is not considered the software arrangements situation of the original operation of these NodeB10, directly NodeB 10 all software modules is all sent to each NodeB 10.That is to say, will download to the base station, original file in the coverage base station after the All Files packing.
The problem of this scheme is that the file of not revising also will be downloaded, and has prolonged download time, and influence is even more serious under the lower situation of bandwidth.
Except above-mentioned software upgrading scheme, also have a kind of scheme, promptly before the edition upgrading, the engineer packs the file that upgraded in advance, and downloads to the base station, original file in the coverage base station.
The problem of this scheme is, need safeguard a database at OMC, be original version information situation in each base station therein, and the version information in this database is strictly consistent with the actual version information in each base station, if inconsistent may causing omitted important file, or repeated downloads unnecessarily.But if communication failure just may make version information in the database and actual different.
Summary of the invention
In view of this, main purpose of the present invention is to provide the method for upgrading base station in a kind of communication system, and feasible efficient to a plurality of upgrading base stations is improved.
For achieving the above object, the invention provides the method for upgrading base station in a kind of communication system, comprise following steps:
Each file that operation maintenance center will upgrade breaks into a upgrade software bag, wherein gathers version information, length and the side-play amount in this upgrade software bag of each file that will upgrade, writes first file of this upgrade software bag;
Operation maintenance center indicates at least one base station to be upgraded to obtain first file of upgrade software bag from this operation maintenance center;
The version information of current each file of version information and this locality in first file is compared in the base station, and downloads the file that needs are upgraded according to the length and the side-play amount of each file that writes down in comparative result and first file from operation maintenance center;
The base station loads downloaded files.
By relatively finding, the main distinction of technical scheme of the present invention and prior art is, elder generation sends to the base station to the version information of each file in the upgrade software bag, and the version information of the version information that relatively receive the base station and local each file is only downloaded the file that this locality does not have or version is different.
The upgrade software bag is a complete version, when generating the upgrade software bag, automatically gather version, size, date and the information such as skew of these files in software kit of the All Files that needs packing, write a file, and this document is added the upgrade software bag as first file.
Difference on this technical scheme, brought comparatively significantly beneficial effect, promptly because the file that this locality does not have or version is different is only downloaded in the base station, so download the method for All Files relatively, the actual needs downloaded files can significantly reduce, thereby has improved downloading efficiency.
Because version relatively carries out in each base station, the local version information that is obtained must be correct, and with respect to the scheme by the version information in each base station of upgrading control device centralized maintenance, the possibility of makeing mistakes reduces greatly.
Because version comparison, file in download are selected, initiation download etc. mainly handled by finishing each base station, with respect to the mode that focuses on by upgrading control device, we can say that the present invention is a kind of " distributed " treatment system to a certain extent, the burden of upgrading control device is lighter, can realize that a large amount of base stations upgrades simultaneously.
Because the upgrade software bag is a complete version, so as long as the equipment development merchant goes out the upgrading requirement that a upgrade software bag just satisfies the communication system of a plurality of different editions.Because stipulated the wherein deposit position of each file version information, so the upgrading control device of each communication system can be obtained version information easily.

Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with accompanying drawing.
Generally speaking, principle of the present invention is, upgrading control device sends to remote sub-system with the version information of each file in the upgrade software bag, and the version information of the version information that remote sub-system is relatively received and local each file is only downloaded the file that this locality does not have or version is different.By making remote sub-system only download the file that this locality does not have or version is different, download the method for All Files relatively, the actual needs downloaded files can significantly reduce, thereby has improved downloading efficiency.
According to the method flow of upgrading remote subsystem in the communication system of a preferred embodiment of the present invention as shown in Figure 3.This embodiment is applied to mobile communication system, and in particular, this preferred embodiment realizes in WCDMA.Wherein, above-mentioned upgrading control device is OMC in the WCDMA system; Remote sub-system is NodeB.Certainly, remote sub-system of the present invention is not limited to NodeB, just as a common example technical scheme is described with NodeB in the present embodiment.
As shown in Figure 3, at first, in step 310, OMC need pack to upgrade software, wherein when generating the upgrade software bag in advance, automatically gather version, size, date and the information such as skew of these files in software kit of the All Files that needs packing, write a file, and this document is added the upgrade software bag as first file.
Then, in step 320, OMC indicates file transfer protocol (FTP) (the File Transfer Protocol of the master control borad of at least one NodeB to be upgraded from OMC, abbreviation " FTP ") first file in the server download and upgrade software kit, content wherein is the version information of each file in the upgrade software bag, and this file can be described as " description document " again in the present invention.Information in " description document " is except the version information of each file, also comprise the skew (original position of each file apart from the skew of upgrade software packet header) of each file in the upgrade software bag, those of ordinary skill in the art can understand, the offset information that file has been arranged, NodeB just can optionally have been downloaded needed file.According to principle of the present invention, OMC can be a plurality of NodeB upgradings simultaneously, and the software version among these NodeB can be identical or different.
It is pointed out that the upgrade software bag can be the complete software version of NodeB, in this case, as long as the equipment development merchant goes out the upgrading requirement that a upgrade software bag just satisfies the communication system of a plurality of different editions.Because stipulated the wherein deposit position of each file version information, so the upgrading control device of each communication system can be obtained version information easily.
In addition, version information can be one of following or its combination in any: the last modification time of version number, file size and file, as long as can correctly identify identical file.
After this, in step 330, NodeB Main Processor ﹠ Timing unit arrives internal memory with the data read in the file, and according to the data in the internal memory, the version information of the version information of relatively receiving and local current each file, and download the file of needs upgrading from MOC according to comparative result.
Specifically, this step can be divided into the version information that following substep: NodeB relatively receives and the version information of local current each file, if the local file of the same name that does not have in the upgrade software bag is then downloaded from upgrading control device (OMC); If local have file of the same name in the upgrade software bag but the version information difference is then downloaded from upgrading control device (OMC).Otherwise, if local file of the same name is arranged in the upgrade software bag, and the version information unanimity, then skip this document, continue more next file.
Thus, by in sending to the upgrade software bag of NodeB Main Processor ﹠ Timing unit, carrying the version information of each file, skip in view of the above the file that does not have renewal, only download the file that was updated.
It is pointed out that in this step because version relatively carries out at each NodeB, the local version information that is obtained must be correct, with respect to the scheme by the version information among each NodeB of OMC centralized maintenance, the possibility of makeing mistakes reduces greatly.
For the file in the download and upgrade software kit optionally, except needs are known the length of wanting downloaded files original position (apart from the skew of upgrade software packet header), file, also require ftp server to want to support breakpoint transmission, REST order just, because redirect realizes by this FTP order, otherwise just can not skip over which file not down, can only progressive download.
At last, in step 340, NodeB loads downloaded files.
This shows, in the present embodiment, because mainly handling by each remote sub-system, version comparison, file in download are selected, initiation download etc. finish, with respect to the mode that focuses on by upgrading control device, we can say that the present invention is a kind of " distributed " treatment system to a certain extent, the burden of upgrading control device is lighter, can realize that a large amount of remote sub-systems upgrades simultaneously.
Though by with reference to some preferred embodiment of the present invention, the present invention is illustrated and describes, those of ordinary skill in the art should be understood that and can do various changes to it in the form and details, and without departing from the spirit and scope of the present invention.
