Translated fromChinese技术领域technical field
本发明涉及一种网络管理系统，尤其涉及一种网管系统中实现对前台数据配置的方法。The invention relates to a network management system, in particular to a method for realizing configuration of foreground data in the network management system.
背景技术Background technique
配置管理是电信等网络管理系统的一项重要功能，它根据业务需求对网络设备和网络资源进行定义和初始化。Configuration management is an important function of network management systems such as telecommunications. It defines and initializes network devices and network resources according to business requirements.
在现有的系统中，进行配置管理的第一种方法是采取人机命令的方式，操作维护人员通过OMC(操作管理中心，Operate Manager Center)下发人机命令到前台，前台解析命令并操作相关的前台数据库表，实现数据的配置。In the existing system, the first method of configuration management is to adopt man-machine commands. Operation and maintenance personnel send man-machine commands to the front desk through OMC (Operate Manager Center), and the front desk parses the commands and operates them. Relevant front-end database tables to realize data configuration.
这种方式的缺点是大大增加了前台的运行工作量，由于配置逻辑都是在前台实现，增加了前台的代码量，不利于前台的运行稳定，降低了前台工作效率。同时，与后台成熟的关系型数据库系统(DBMS)相比，前台嵌入式数据库功能相对简单，例如，不能很好的提供事务操作的功能，一旦配置过程中出现数据异常，恢复正确的数据比较困难。The disadvantage of this method is that it greatly increases the workload of the front desk. Since the configuration logic is implemented in the front desk, the amount of code in the front desk is increased, which is not conducive to the stable operation of the front desk and reduces the work efficiency of the front desk. At the same time, compared with the mature relational database system (DBMS) in the background, the function of the embedded database in the foreground is relatively simple. For example, it cannot provide the function of transaction operation very well. Once a data exception occurs during the configuration process, it is difficult to restore the correct data. .
第二种方法是把前台配置数据先传送到后台，在后台转化成数据库格式，如DBF文件，然后编辑这些数据库文件，再转换成前台数据格式，传送到前台保存。The second method is to transfer the front-end configuration data to the back-end first, then convert it into a database format, such as a DBF file, and then edit these database files, and then convert it into a front-end data format, and then send it to the front-end for storage.
这种方法的缺点是每次进行数据配置的时候都要把前台数据先传送到后台，不够方便。而且由于一次配置数据一般涉及很多文件，对于大型通讯系统(例如GSM)，后台在编辑DBF等格式的文件时很难保证数据的正确性和对事务的完整操作。The disadvantage of this method is that the foreground data must be transmitted to the background every time data configuration is performed, which is not convenient enough. And because one configuration data generally involves many files, for large-scale communication systems (such as GSM), it is difficult to ensure the correctness of data and the complete operation of transactions when editing files in formats such as DBF in the background.
发明内容Contents of the invention
本发明所要解决的技术问题在于提供一种网管系统中实现对前台数据配置的方法，能够在减轻前台工作量的同时，充分利用后台关系型数据库系统的强大功能，使配置数据更加可靠。The technical problem to be solved by the present invention is to provide a method for configuring front-end data in a network management system, which can reduce the workload of the front-end and make full use of the powerful functions of the back-end relational database system to make the configuration data more reliable.
为了解决以上技术问题，本发明提供了一种网管系统中实现对前台数据配置的方法，包括以下步骤：In order to solve the above technical problems, the present invention provides a method for implementing front-end data configuration in a network management system, comprising the following steps:
(a)后台数据库模拟前台数据库系统创建相关配置表，并创建待传输数据表和前后台数据库对应关系表，以及用于实现配置逻辑的自定义存储过程；(a) The background database simulates the front-end database system to create related configuration tables, and creates the corresponding relationship table between the data table to be transmitted and the front-end and back-end databases, and a custom stored procedure for implementing configuration logic;
(b)操作维护人员下发数据配置请求；(b) Operation and maintenance personnel issue data configuration requests;
(c)网管程序收到数据配置请求后，调用相关的自定义存储过程，生成配置数据；(c) After the network management program receives the data configuration request, it calls the relevant custom stored procedure to generate the configuration data;
(e)操作维护人员发送数据同步请求；(e) The operation and maintenance personnel send a data synchronization request;
(f)网管程序收到数据同步请求后，根据所述待传输数据表读取要传输的配置表的数据，依据所述前后台数据库对应关系表进行数据转换后，与前台交互，把数据传送到前台；(f) After the network management program receives the data synchronization request, it reads the data of the configuration table to be transmitted according to the data table to be transmitted, and after performing data conversion according to the corresponding relationship table of the front and back databases, interacts with the front desk to transmit the data to the front desk;
(g)前台接收配置数据，在接收完成后，把数据保存到前台数据库中。从而完成对前台的数据配置。(g) The foreground receives the configuration data, and saves the data in the foreground database after receiving. Thus completing the data configuration of the foreground.
为了实现增量同步和整表同步两种方式，上述方法中：所述步骤(c)中还将修改过的配置表在所述待传输数据表中的标记置为“需传输”状态；所述步骤(e)中，操作维护人员可发出增量同步或整表同步的请求；所述步骤(f)中，当网管程序接收到增量同步的请求后，只读取待传输数据表中传输标记为“需传输”状态的配置表数据，而在收到整表同步的请求后，读取待传输数据表中所有配置表的数据。In order to realize the two modes of incremental synchronization and full table synchronization, in the above method: in the step (c), the mark of the modified configuration table in the described data table to be transmitted is set to "need to transmit" state; In the above step (e), the operation and maintenance personnel can send a request for incremental synchronization or full table synchronization; in the above step (f), after the network management program receives the request for incremental synchronization, it only reads the Transfer the configuration table data marked as "need to transfer", and read the data of all configuration tables in the data table to be transferred after receiving the request for synchronization of the entire table.
在一个后台数据库对应于多个前台模块且需有选择地进行数据配置时，所述步骤(e)中，操作维护人员还从网管终端选择要进行数据配置的网元并下发，网管程序根据所述网元从待传输数据表中选取与其相关的配置表。When a background database corresponds to multiple foreground modules and data configuration needs to be selectively performed, in the step (e), the operation and maintenance personnel also select the network element to be configured with data from the network management terminal and issue it, and the network management program according to The network element selects a configuration table related to it from the data table to be transmitted.
由上可知，本发明方法在后台数据库成熟的大型关系型数据库系统中，采用自定义过程来实现配置逻辑，可以很好的实现事务等功能，降低错误的概率。而且，由于配置逻辑是由在后台数据库中实现，因而减轻了前台的负担，提高了前台工作效率。可以在网管系统中实现对电信等网络设备和网络资源的高效配置。It can be seen from the above that the method of the present invention uses a self-defined process to implement configuration logic in a large-scale relational database system with a mature background database, which can well implement functions such as transactions and reduce the probability of errors. Moreover, since the configuration logic is implemented in the background database, the burden on the front desk is reduced and the work efficiency of the front desk is improved. Efficient configuration of telecommunications and other network equipment and network resources can be realized in the network management system.

具体实施方式Detailed ways
下面以个人便携电话系统(PHS)系统的网管系统为例，详细介绍本发明的实施方法。Taking the network management system of the personal portable telephone system (PHS) system as an example, the implementation method of the present invention will be introduced in detail below.
PHS系统是成熟发展的一种个人移动通讯系统，从技术体制上是一种有线接入网技术和移动切换技术相结合的产物，属于2.5G的移动通讯产品。PHS网管系统是PHS系统的一个子系统。本实施例中，PHS网管系统为标准客户机/服务器结构，后台数据库采用Microsoft SQL Server，操作维护人员使用图形用户界面(GUI)终端通过PHS网管服务器(即后台服务器)访问SQL Server数据库。后台系统和前台系统之间通过TCP/IP协议通信。The PHS system is a mature personal mobile communication system, which is a combination of wired access network technology and mobile switching technology in terms of technical system, and belongs to 2.5G mobile communication products. The PHS network management system is a subsystem of the PHS system. In this embodiment, the PHS network management system is a standard client/server structure, and the background database adopts Microsoft SQL Server, and the operation and maintenance personnel use a graphical user interface (GUI) terminal to access the SQL Server database through the PHS network management server (i.e. the background server). Communication between background system and foreground system through TCP/IP protocol.
首先，SQL Server数据库模拟前台数据库表结构创建相关配置表，所谓模拟是指二者的结构(如字段名称、字段类型、字段长度等)几乎一致。但是，由于前后台数据库的类型不同，也可能存在不一致的问题，这时需要在传送之前加以数据格式转换。First, the SQL Server database simulates the table structure of the foreground database to create related configuration tables. The so-called simulation means that the structures (such as field names, field types, field lengths, etc.) of the two are almost the same. However, due to the different types of front-end and back-end databases, there may also be inconsistencies. In this case, data format conversion is required before transmission.
在数据配置过程中，后台数据库上要根据操作维护人员的配置请求，在后台数据库上完成配置逻辑。在同步时，还需确定需传输哪些表和传输到哪些前台模块，以及根据前后台数据库配置表的对应关系进行数据转换。During the data configuration process, the background database should complete the configuration logic on the background database according to the configuration request of the operation and maintenance personnel. When synchronizing, it is also necessary to determine which tables need to be transferred and which front-end modules to transfer to, and perform data conversion according to the corresponding relationship between the front-end and back-end database configuration tables.
本实施例中，后台数据库安装的时候创建了用于实现配置逻辑的自定义存储过程。这些自定义存储过程可以根据操作维护人员下发的配置请求，用软件自动完成对所有相关数据库中数据的相应修改，完成配置逻辑，其可靠性要高于对数据库文件的编辑。In this embodiment, a custom stored procedure for implementing configuration logic is created when the background database is installed. These custom stored procedures can automatically modify the data in all related databases by software according to the configuration requests issued by the operation and maintenance personnel, and complete the configuration logic. Its reliability is higher than that of editing database files.
PHS网管系统数据配置包括整表同步和增量同步两种类型，整表同步是把后台数据库全部配置表的数据同步到前台，一般在开局时使用，增量同步是同步自上次同步以来修改的表的数据，增量同步涉及的数据比较少，一般在系统运行维护时使用。PHS network management system data configuration includes two types of full table synchronization and incremental synchronization. Full table synchronization is to synchronize the data of all configuration tables in the background database to the foreground. It is generally used at the beginning of the deployment. Incremental synchronization is to synchronize changes since the last synchronization. Incremental synchronization involves less data, and is generally used during system operation and maintenance.
为了确定同步时需传送的表，后台数据库在安装的时候创建了待传输数据表send_table，对其数据初始化时写入了后台数据库中涉及配置数据的表名Tablename，以及网元号(代表前台模块号)和是否需要传输的标记IsSend，传输标记用于识别配置表是否为“需传输”状态。send_table表的结构如表1所示，但本发明并不局限于此。In order to determine the table to be transmitted during synchronization, the background database created the data table send_table to be transmitted during installation, and wrote the table name Tablename involving configuration data in the background database and the network element number (representing the front-end module) when initializing its data. No.) and the flag IsSend of whether transmission is required, and the transmission flag is used to identify whether the configuration table is in the state of "transmission required". The structure of the send_table table is shown in Table 1, but the present invention is not limited thereto.
表1，待传输数据表(send_table)Table 1, the data table to be transmitted (send_table)
为了反映前后台数据库中配置表的对应关系，以及表与表之间的结构对应关系，本实施例的PHS网管系统数据库在安装时，创建了反映前后台数据库对应关系的关系表table_book，数据初始化时将前后台涉及配置数据的数据库表信息写入该表中，网管服务器程序根据表table_book进行数据转换和表的对应。本实施例的table_book表的结构如表2所示，包括后台表名、后台表字段名、后台表字段类型和长度，以及相对应的前台表名、前台表字段名、前台表字段类型和长度等字段。但该表只是一个示例，其中的字段也可以根据情况省略或增加。In order to reflect the correspondence between the configuration tables in the front-end and back-end databases, and the structural correspondence between the tables, the PHS network management system database of this embodiment created a relational table table_book reflecting the correspondence between the front-end and back-end databases when it was installed, and the data was initialized At this time, the database table information related to the configuration data of the front and back is written into the table, and the network management server program performs data conversion and table correspondence according to the table table_book. The structure of the table_book table of the present embodiment is as shown in table 2, comprises background table name, background table field name, background table field type and length, and corresponding foreground table name, foreground table field name, foreground table field type and length and other fields. But this table is just an example, and the fields in it can also be omitted or added according to the situation.
表2，前后台数据库对应关系表(table_book)Table 2, front and back database correspondence table (table_book)

步骤140，PHS网管服务器接收PHS网管终端发来的配置请求，处理后调用后台数据库相应的自定义存储过程，把配置数据写入后台数据库SQLServer相应的表；
步骤150，后台数据库把修改过的配置表在待传输数据表send_table中对应的isSend字段设置为1，以便在增量同步时查询哪些表是修改的；
步骤160，操作维护人员在数据配置完成后，从PHS网管终端选择网元(即数据传输到的前台模块)，下发数据同步请求；
步骤170，PHS网管服务器分析数据同步请求的类型，如果是整表同步，执行步骤180a，如果是增量同步，执行步骤180b；
步骤180a，从send_table取出所选网元对应的全部配置表，依据前后台数据库的对应关系表table_book，将取出的数据在PHS网管服务器的内存中转化为前台可以接收的数据；
步骤180b，从send_table表中取出所选网元对应的变动表(isSend等于1的表)，依据前后台数据库的对应关系表table_book，将取出的数据在PHS网管服务器的内存中转化为前台可以接收的数据；
步骤190，PHS网管服务器向前台发送数据同步请求，在得到应答后，以TCP/IP协议向前台传送配置数据；
步骤200，前台先将接收到的配置数据写入前台数据库临时表；
步骤210，在数据传送完成，PHS网管服务器向前台发送数据存盘请求；
步骤220，前台把前台数据库临时表的数据拷贝到前台数据库实际表中，数据同步结束。
本发明方法在网管系统的后台数据库中模拟前台数据库系统创建相关配置表，后台数据库使用自定义存储过程来实现配置逻辑，在配置数据全部生成后，通过后台到前台的数据同步来实现对电信等网络设备和网络资源的配置。因而采用本方法，能节省前台有限的CPU、内存等资源，提高前台的工作效率，同时，能充分利用后台关系型数据库系统的强大功能，使配置数据更加可靠。通过使用这种方法，操作维护人员可以通过OMC的图形化终端对网络进行灵活、高效的配置，并可以保证数据完整性，同时对系统负荷影响极小。The method of the present invention simulates the foreground database system in the background database of the network management system to create related configuration tables. The background database uses a custom storage process to realize the configuration logic. Configuration of network devices and network resources. Therefore, this method can save limited resources such as CPU and memory in the foreground, and improve the work efficiency of the foreground. At the same time, it can make full use of the powerful functions of the background relational database system to make the configuration data more reliable. By using this method, the operation and maintenance personnel can configure the network flexibly and efficiently through the graphical terminal of the OMC, and can ensure data integrity with minimal impact on the system load.
虽然本发明实施例是以PHS网管系统为例，但本发明方法可适用于各类网管系统中，当然该网管系统的后台要与前台系统相连。Although the embodiment of the present invention takes the PHS network management system as an example, the method of the present invention is applicable to various network management systems, and of course the background of the network management system must be connected with the foreground system.
