Description

Directory architecture of multiple version package in mobile communication and method for downloading multiple version package using the same}

The present invention relates to multi-version package downloading in a mobile communication system, in particular a directory of multi-version packages in a mobile communication system capable of downloading different versions of a package from a base station manager to a base station controller and a base station. The present invention relates to a structure and a multi-version package downloading method using the same.

The mobile communication system is composed of a mobile terminal (mobile phone), a base transceiver station (BTS), a base station controller (BSC) and a mobile switching center (MSC). Its signal format is changed to be suitable for the wireless link and the wired link. The base station controller is a function of each element of the base station and an access means between cell operators, base station operation management, service state management of hardware and software in the base station, and call traffic. It performs monitoring functions such as allocation and configuration of resources for resource collection, collection of information on base station operation, base station operation, sub-devices related to monitoring and fixing. The switching center configures an access point for user traffic between the base station controller management and the mobile communication network and the mobile switching center of the general telephone network or the same mobile communication system.

Management of such a mobile communication system is performed by a base station manager (BSM), which is a programmable loading data (hereinafter referred to as a PLD) required for operating a mobile communication system and each network in the system. Application software running on the Network Element is downloaded to the base station controller and the base station.

In the current mobile communication system, one base station manager is connected to up to 12 base station controllers, and one base station controller is designed to be connected to up to 48 base station controllers, so that one base station manager is connected to up to 12 base station controllers and 576 base stations. It is responsible for downloading data (software) for.

Here, the PLD is static data that is hardly changed, such as hardware shape information, information resources, loading tables, system constants, etc., and is a database resident independently of a program in a certain area of the main memory for real time processing. The data is represented in a table form.

Hereinafter, a directory structure for downloading software in a base station manager of a mobile communication system according to the related art will be described with reference to the accompanying drawings.

1 is a diagram illustrating a directory structure for software downloading in a base station manager of a mobile communication system according to the prior art.

The directory for downloading different versions of a package from a base station manager (BSM) to a base station controller or base station is an executable file directory (EXEC) in which an executable application program for executing the base station manager exists. (20), a data directory (DATA) 30 in which data other than the execution application program exists, and an application directory (LDNGAPP) which stores application software to be downloaded as a directory under the data directory 30 ( 40) and a PLD directory (LDNGPLD) 50 which stores a PLD to be downloaded. At this time, the package directory (R1.0) 10 is a directory above the executable file directory 20 and the data directory (R1.0) 30.

In this case, the directory refers to a space separated from each other in order to store related files in a group. However, other unrelated files are stored in different directories so that they are not mixed.

The structure of a block information (blkinfo) file for software downloading in a base station manager of a conventional mobile communication system having such a directory structure is shown in FIG.

First, the block information (blkinfo) file 60 of FIG. 2 includes an application directory 40 under the data directory 30 and a PLD directory 50 among the directories under the package directory 10 in the directory structure shown in FIG. The block information (blkinfo) file 60 is a data file used to determine which application block (SOFTWARE) and PLD to download to the base station controller and each processor of the base station.

The block information (blkinfo) file 60 has a list of files to be downloaded to the base station controller and each processor of the base station, and each list includes three integer values called prmode (prmode1, prmode2, prmode3) and version information.

Here, one block information (blkinfo) file 60 is fixed to one application directory for storing files to be downloaded, and the block information (blkinfo) file 60 itself is also one version (R1.0.0 in FIG. 2). You can see that it is configured to only have a list of packages.

The base station manager having data in the file format as shown in FIG. 2 receives a software list request from the base station controller or any (optional) processor of the base station, and a block list of the block information (blkinfo) file 60; By referring to the prmode value, a list of files to be downloaded (loading table) to the processor is created, and the files written in the loading table are downloaded.

In the software downloading in the base station manager of the conventional mobile communication system as described above, the directory for storing the downloaded files is fixed to one, and the block information (blkinfo) file itself has only one version of the package list. Therefore, there is a problem in that the files of several versions of the package are stored together so that different versions of the files cannot be simultaneously downloaded to different base stations or base station controllers.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art, and includes a plurality of directories for storing applications of a package managed by a base station manager, and different versions of a plurality of application directories from respective application directories to respective base station controllers and base stations. The present invention provides a directory structure of a multi-version package and a multi-version package download method using the same in a mobile communication system capable of downloading a package.

According to one aspect of the present invention, the base station includes an executable file directory in which an execution application program for executing a base station manager exists, a data directory in which data except the execution application program exists, and a subdirectory of the data directory. A plurality of application directories storing application software including information files for different versions of packages to be downloaded from the manager to each of the plurality of base stations or base station controllers, and the targets of downloading as subdirectories of the data directory. It consists of a Programmable Loading Data (PLD) directory that stores Programmable Loading Data (PLD).

Preferably, the information file for the different versions includes a plurality of block information files including package name information, downloading directory information identifying a downloading directory, and annotation data about additional information, and blocks of the plurality of application directories. The information file consists of a package information file that provides information about the base station or base station controller to be optionally downloaded.

According to another aspect of the present invention for achieving the above object, the step of the base station manager receiving a software download request from the processor of the base station or the base station controller to retrieve the version information of the application software of the base station or base station controller to which the processor belongs; And a list of files to be downloaded to the base station or the base station controller which has requested the downloading from a plurality of application directories including information files of different versions of packages managed by the base station manager according to the search result. And the downloading of the files written in the list to the base station or the base station controller.

Hereinafter, a configuration and an operation according to an exemplary embodiment of the present invention will be described with reference to the accompanying drawings.

3 is a diagram illustrating a directory structure for software downloading in a base station manager of a mobile communication system according to the present invention.

The structure of the directory for software downloading in the base station manager of the mobile communication system according to the present invention may configure a plurality of application directories, which are directories for storing applications to be downloaded, so as to store applications of multiple versions. .

That is, as shown in Figure 3, the directory for downloading a different version of the package (package: general purpose program) from the base station manager (BSM) to the base station controller or the base station is a top-level package directory (R1.0) 110, An executable file directory (EXEC) 120 in which an executable application program for executing the base station manager exists as a directory under the package directory 110, a data directory DATA 130 in which data except for the executable application program exists, and , A plurality of application directories (LDNGAPP) 140a, ... 140n that store application software to be downloaded as a directory under the data directory 130, and a PLD that stores PLDs to be downloaded. Directory (LDNGPLD) 150, where each base station from a plurality of application directories 140a, ... 140n is created. In order to set the base station and the base station to download the software at the same time, the block information (blkinfo) file is composed of the same number of first to nth application directories 140a, ... 140n, A package information (PKGinfo) file is placed to determine which block information (blkinfo) file and application directory to download when downloading from each base station and base station controller.

FIG. 4A is a diagram showing the structure of a package information (PKGinfo) file for software downloading in a base station manager of the mobile communication system shown in FIG. 3, and FIG. 4B is a diagram showing the structure of a block information (blkinfo) file.

First, the package information (PKGinfo) file 160 as shown in FIG. 4A specifies which block information (blkinfo) file to refer to when downloading to each base station controller and the base station.

At this time, in the structure of the package information (PKGinfo) file 160, two digits such as 00, 01, 02, ... represents the base station controller of the corresponding number, 0000, 0001, 0002, 0100, 0101, 0102 The four digits represent the base station controller and the base station under the base station controller.

For example, 0000 represents base station 0 of base station controller 0, 0001 represents base station 1 of base station 0 controller, and 0002 represents base station 2 of base station controller 0.

In addition, 0100 represents base station 0 of the base station controller 1, 0101 represents base station 1 of the base station controller 1, and 0102 represents base station 2 of the base station controller 1.

The structure of the first and second block information (blkinfo) files 171 and 172 designated for each base station controller and the base station in the package information (PKGinfo) file 160 is basically a block information (blkinfo) file in the conventional downloading method. It is similar to the structure (60 in FIG. 2) except that it has three additional fields in the file header part.

That is, the structure of the first and second block information (blkinfo) files 171 and 172 as shown in FIG. 4B has a package name (#PKGNAME) and a downloading directory (#LDNGDIR) which are not present in the block information (blkinfo) file according to the prior art. You can see that three pieces of information have been added: comments and #COMMENT.

Here, the package name (#PKGNAME) at the top of the first and second block information files (171, 172) is an information area for writing the package name to distinguish the package, and the download directory (LDNGDIR) can be actually downloaded. This is an information area that writes the name of the application directory (LDNGAPP) that stores the files. Finally, the comment item is an information area that describes the characteristics and additional information of each package.

In the multi-version package downloading method in the mobile communication system of the present invention, the base station manager receives a software download request from a base station controller or any (random) processor of the base station, once the package information (PKGinfo) file 160 The base station controller or the base station to which the processor which requested the downloading request belongs is searched to determine which block information (blkinfo) file to obtain information related to downloading.

Next, a list (loading table) of files to be downloaded to the processor is created by referring to the block list and prmode value of the block information (blkinfo) files 171 and 172 determined from the package information (PKGinfo) file 160, and the loading table Download files created in. At this time, the application block to be downloaded is read from the application directory (one of 140a, ... 140n) specified in the application directory entry specified in the corresponding block information (blkinfo) file (one of 171, 172), and optionally to the base station or base station controller. Download

In this case, since the PLD files exist as separate files for the processors of each base station and the base station controller, the PLD files may be operated as one of the PLD directories 150 unlike the application directories 140a and 140n.

As described above, the present invention facilitates an operation experiment applying a new version of a package for a specific base station and a base station controller when a test package or a new package is applied when downloading a software from a base station manager to a base station and a base station of a mobile communication system. If there is a problem with the new version of the package according to the experimental results, it can be easily recovered with only the package information file, and if there is no problem, it is only necessary to manipulate the package information file when applying the new version of the package to all base stations and base station controllers. You can also update easily.
