Description

电信设备服务端与客户端进行通^f言的方法技术领城本发明涉及通信技术领域,尤其涉及一种电信设备服务端与客户端进行通信的方法。 Telecommunication device for the server and the client is made through ^ f TECHNICAL collar city present invention relates to communication technologies, and particularly to a method of telecommunication device communicating with the server client. 背景技木MML (Man Machine Language,即人才几界面语言)命令是在电信领域内广泛使用的命令体系,负责实现支持MML的客户端同服务器的有效通信,如运用于交换机或智能网设备的维护、管理等。 Background wood technology MML (Man Machine Language, that is, a few people Interface Language) command is a command system widely used in the field of telecommunications, the customer is responsible for implementing effective communications support MML end with a server, such as a switch or apply maintenance intelligent network devices and management. MML命令的基本形式如下示例:ADD VPN GRP: GRPID=8888888888, PROVINCE=03, SERVAREA =03075501, GRPTYPE=0, GRPNAME-My Group;上例中ADD VPN GRP称为命令字或操作码(Command Code ),业务操作码多数为三段式,由动词+业务名+操作对象构成,操作码用于唯一标识一个操作。 MML command basic form is as follows Example: ADD VPN GRP: GRPID = 8888888888, PROVINCE = 03, SERVAREA = 03075501, GRPTYPE = 0, GRPNAME-My Group; the embodiment ADD VPN GRP called a command or operation code word (Command Code) , mostly three-stage operational code, name service consists verb + + operation target, the operation code used to uniquely identify an operation. 冒号必须紧跟着操作码,即使没有后续的^:也必须有冒号。 Colon must be followed by an operation code, even if there is no subsequent ^: must have colon. 冒号后面跟随一系列的操作参数,形式为字段名称和值的对,即Named Value,各員之间用逗号分割,参数分必选和可选两种。 After a colon following a series of operating parameters in the form of field names and values, i.e. Named Value, divided by commas between the members, the required and optional parameters of two kinds of points. MML命令中参数的顺序是随意的,没有先后之分。 MML command in the order parameter is random, no particular order. MML命令的操作结果同样以MML的形式返回,这类MML称为ACKMML (MML命令响应),其形式为:ACK: ADD VPN GRP: RETN=0, DESO成功; Result MML command also returns in the form of MML, such MML referred ACKMML (MML command response), which is in the form of: ACK: ADD VPN GRP: RETN = 0, DESO successful;

在利用MML命令作为业务接口进行通信的服务端与客户端业务系统中,当服务端业务逻辑升级的时候,就会要求所有客户端跟随逬行升级,否则就会造成接口不兼容,导致业务无法开展。 In the end as a business service interface to communicate with the client using the MML command system business, when the server-side business logic of an upgrade, it will require all clients to follow Peng line upgrade, otherwise it will cause the interface is not compatible, can not lead to business carried out. 目前在电信领域内, 服务端和客户端业务系统大多数由不同公司开发完成,因此接口上的变动需要各方协调完成,经常耗费大量的人力物力。 Currently in the field of telecommunications, services and client most complete business systems developed by different companies, so the changes on the interface requires the parties to coordinate the completion, often spend a lot of manpower and resources. 如图1所示为在服务端运行新旧两套业务系统结构示意图,现有技术大多数系统采用在服务端和客户端分别利用新、旧不同版本业务逻辑的两套业务系统分别运行新、旧两套业务,如:在服务端既有Vl.O版本的业务,又有V2.0版本的业务,而不同版本采用不同的^^务名来实现, 分别通过新、旧版本MML命令与新、旧版本客户端进行通信。 Shown as a schematic system configuration of the old and new sets of services running on the server side, most prior art systems employ a server and the client, respectively the use of the new and old versions of the business logic of the two different business systems are running the old and new two sets of business, such as: both Vl.O version of the business, but also in business V2.0 version of the server, and different versions of different business name ^^ be achieved, namely the adoption of new, old and new versions of MML command the old version of the client to communicate. 这种新、旧业务同时运行的方法存在以下弊端:1、 增加了服务端的负担,这对于瘦客户肥服务的系统尤其明显, 两套业务系统会使得服务器不堪重负。 This new, there is the old method of running the business at the same time the following drawbacks: 1, increasing the burden on the server, which is particularly evident for fat thin client system service, two business systems will make the server overwhelmed. 2、 增加了维护工作,对于在旧版本的业务逻辑中发现的缺陷,不仅要在新版本中修改,同时仍旧要修改旧版本。 2, increased maintenance work, for defects found in older versions of the business logic, not only to modify the new version, but still want to modify the old version. 3、 客户端无法实现业务的平滑升级,由于采用新旧版本两套独立的业务系统,客户端要么是新版本的,要么是旧版本,无法实现在大部分是旧版本的情况下,使用新版本的部分功能。 3, clients can not achieve a smooth upgrade services, the use of the old and new versions of two independent business systems, client or the new version, either the old version, can not be achieved in most cases is the old version, the new version Some of the features. 4、 对服务端,如果新、旧业务数据库表结构不同,则无法实现共用数据库。 4, on the service side, if the old and new business different database table structure, you can not achieve a shared database. 现有技术也可采用在新业务中仍旧保留旧业务接口的方法实现,如图2所示, 一个服务实际上提供两套协议,在服务端只运行新版本业务逻辑,并提供新、旧版本协议接口,分别通过新、旧版本MML命令与新、旧版本客户端进行通信。 The method of the prior art may also be employed still keep the old service interface implemented in the new service, shown in Figure 2, a service is actually provided two sets of protocol, only the new version running service logic on the server side and new, old version protocol interface, respectively, to communicate through the new and old versions of MML command with the new and old versions of the client. 这种新业务系统保留旧业务接口的方法无疑也会增加服务端的开发工作,因为服务端必须要利用很多的判断来鉴别MML命令的版本。 This method of new business systems to keep the old interface will no doubt increase business development server, because the server must use a lot of judgment to identify the version of the MML command.

而且当客户端升级到新版本后,原来的旧接口又要乂人服务端剥离,增加了复杂度,从而导致开发成本的上升。 And when the client upgrade to the new version, the original old server interfaces but also stripped Yi in person, increase the complexity, resulting in increased development costs. 当要求兼容的旧版本不止一个的时候,实现起来相当困难。 When asked compatible with older versions of more than one time, very difficult to implement. 发明内容本发明所要解决的技术问题是:克服现有的利用MML语言进行通信的客户端与服务端在升级时实现困难、成本高的缺点,提供一种电信设备服务端与客户端进行通信的方法,方便客户端与服务端的升级,从而节约客户端与服务端的开发成本,并实现对客户端的平滑升级。 The present invention solves the technical problem: to overcome the existing use of MML language for client and server communication is difficult to achieve when you upgrade, the high cost disadvantages and to provide a telecommunications device server to communicate with clients the method, easy to upgrade client and server, thereby saving development cost client and server, and to achieve smooth upgrade client. 本发明为解决上述技术问题所采用的技术方案为: 这种电信设备服务端与客户端进行通信的方法,其特征在于:它包括以下步骤:在采用协议命令各字段顺序不受限制的协议进行通信的电信设备的服务端与客户端,服务端采用新版本业务处理逻辑,并提供相对于所述业务处理逻辑独立的协议版本转发进程;利用所述的转发进程在服务端与客户端通信时,对服务端的新版本协议命令与各客户端的旧版本协议命令进行相互转换。 Aspect of the present invention to solve the above technical problem is as follows: This method for communicating with a telecommunication device for the client server, characterized in that: it comprises the following steps: each command sequence field in the protocol unrestricted use of the protocol server telecommunication device communicating with a client, the server uses a new version business logic, and provides service processing logic with respect to the protocol version independent forwarding process; forwarding process utilizes the service and the client side communication , the new version of the server protocol commands with the old version of the client protocol commands from one into another. 所述的协议命令为人机界面语言(MML)命令。 The man-machine interface protocol command language (the MML) command. 各个不同的客户端配置不同的终端标识,服务端建立这些终端标识与协议版本的对应关系,进行通信时,服务端根据终端标识取得协议版本,由所述的转发进程根据终端标识的不同进行不同的转发处理。 When the various different configuration of the client terminal identification, the server identification and the establishment of these terminals correspondence between protocol version, for communication, the server identifier acquisition protocol version according to the terminal, by the forwarding process for the terminal identification according to various different forwarding. 所述的转发进程将各客户端发出的旧版本协议命令转换为与服务端相应的新版本协议命令。 The forwarding process to convert older versions of each protocol command is sent by the client and server corresponding new version of the protocol commands. 对于新版本协议命令新增的参数,由所述的转发进程增加,取值按服务端业务逻辑取适当的缺省值;对于新版本协议命令删除的参数,由所述的转发进程删除。 For the new version of the protocol commands the new parameters, the increase by the forwarding process, the value of the default values ​​by taking appropriate server-side business logic; the parameters for the new version of the protocol command to delete, delete the forwarding of the process. 对于新版本协议命令值域发生缩小的参数,由所述的转发进程对超过新版本范围的值在新版本协议命令的值域范围内进行等价替换处理,赋予一个值域范围内最接近的值。 For the new version of the protocol command occurs narrow range of parameter values ​​exceeds the range of the new version of equivalents may be substituted within the range of values ​​processed in the new version of the protocol by forwarding the command according to the process, within a range imparting closest range value. ;对于新版本协议命令值域发生扩大的参数,转发进程不作处理。 ;

下面4艮据附图和实施例对本发明作进一步详细说明:为了最大限度的节省客户和开发方的成本,同时实现业务的平滑升级,本发明通过在服务端进行MML接口协议版本转换来解决兼容问题, 使得兼容逻辑和业务逻辑分离,服务端只采用新版本业务逻辑。 According to figures 4 and following gen embodiments of the present invention will be further described in detail: In order to maximize cost savings and the client side of the development, while achieving a smooth upgrade service, the present invention MML protocol version on the server side interface conversion solved by compatible issues, making compatible logic and business logic, server-side business logic using only the new version. 如图3所示为本发明进行MML接口协议版本转换的系统结构示意图,在服务端提供MML接口协议版本转发器,转发器提供独立的转发进程,与业务逻辑分离,转发器进程对外提供统一的服务名。 FIG system structure diagram MML protocol version interface converter is shown in FIG. 3 of the present invention, there is provided a repeater MML interface protocol version on the server, the repeater provides forwarding process independent, separate from the business logic, the repeater processes provide external unified Service Name. 服务端业务系统采用新版本业务逻辑,MML接口协议版本转发器将月k务端的新版本MML命令与各客户端的不同版本的MML命令进行转换。 Server business systems using the new version of the business logic, MML protocol version of the interface transponders different versions of the new version of the business end of the month k MML command with each client MML command to convert. 转发器进程针对新、旧版本协议的不同之处进行转换,消除不兼容的地方。 Transponders for different process to convert the old and new version of the protocol, the elimination of incompatibilities. 这里充分利用了MML命令的特点,MML命令一般由一个命令码跟随若干参数名称与参数值的对组成,MML命令不同的情况包括: 参数名称不同、增加或减少了某些参数、参数值的取值范围不同等。 Here full use of the characteristics of MML command, a MML command is typically a command code following the name of a number of parameters and the parameter values ​​of the composition, where the different MML commands include: different parameter name, increase or decrease of certain parameters, the parameter values ​​takes different range like. 由于MML命令参数的顺序是随意的,没有先后之分,因此不同版本的这些MML命令不同的情况都可通过MML接口协议版本转发器对MML 命令进行修改来实现。 Since the order of MML command parameter is random, no particular order, so Different versions of these cases MML command can be modified to implement the interface protocol version by MML MML command to a repeater. 由于修改本身并不会消拟艮多处理时间,因此采用这种方式处理兼容问题不会影响系统的整体性能。 Since the modified proposed Gen itself does not draw a multi-processing time, thus treated in this manner does not affect the compatibility of the overall system performance. 如要客户端与服务端都为新版本的协议命令,则转发器不需进4亍协议转换处理。 To both client and server versions of the protocol for the new command, the transponder does not need right foot into 4 protocol conversion process. 当客户端发出旧版本的协议命令到服务端时,转发过程如下:1、 对于新版本MML命令新增的参数,由转发器增加,取值按服务端业务逻辑取适当的缺省值。 When the client sends a protocol command to the old version of the server, the forwarding process is as follows: 1, the new version of the new parameters MML command, increases by the repeater, the value taken by an appropriate default value of the business logic server. 2、 对于新版本MML命令删除的参数,由转发器进行删除。 2, the parameters for the new version of the MML commands to delete, delete the transponder. 3、 对于新版本MML命令值域发生缩小的参数,由转发器对超过新版本范围的值进行等价替换处理,赋予一个值域范围内最接近的值。 3, the new version of the MML command parameters have narrow range of values ​​exceeding the range of the new version of equivalents may be substituted processed by the repeater, the nearest value in a given value range. 4、 对于新版本MML命令值域发生扩大的参数,转发器不作处理。 4, for expanding the parameters of the new version of the MML command range occur, the transponder not be processed. 5、对于新版本MML命令的ACK响应命令中值域的增加,转发器进行等价替换处理,赋予一个值域范围内最接近的值。 5, a new version of an ACK command MML command in response to increasing values, the forwarder equivalent replacement process, imparting a closest value within the range of values. 当服务端发出新版本协议命令到旧版本客户端时,转发过程与上述过程相反,具体如下:1、 对于新版本MML命令新增的参数,由转发器对新增参数进行删除。 When the server issues a new version of the protocol commands to older clients, the forwarding process is opposite to the above process, as follows: 1, the new version of the MML command the new parameters, new parameters by the deletion of the transponder. 2、 对于新版本MML命令删除的参数,由转发器增加,取值按客户端业务逻辑取适当的缺省值。 2, the parameters for the new version of the MML command to remove by the transponder increases, the value of the client business logic by taking appropriate default value. 3、 对于新版本MML命令值域发生缩小的参数,转发器不作处理。 3, the new version of the MML commands narrow range of parameters occur, the transponder will not be processed. 4、 对于新版本MML命令值域发生扩大的参数,由转发器对超过旧版本范围的值进行等价替换处理,赋予一个值域范围内最接近的值。 4, the new version MML command parameter range expansion occurs, the old version of the value exceeds the range of equivalents may be substituted processed by the repeater, the nearest value in a given value range. 转发器提供客户端版本可配置功能,允许客户端通过在消息中提供附加信息来发送不同版本的MML命令。 Transponder can be configured to provide client version feature allows clients by providing additional information in the message to send different versions of the MML command. 如图3所示,各个不同的客户端配置不同的终端标识,终端标识是MML接口协议的一个标准组成部分,用于唯一地标识一个客户端,转发器维护一张表,表中记录了终端标识和协议版本的对应关系,此表的内容可配置。 3, the various client configuration different terminal identifier, terminal identifier is a standard part of MML interface protocol, used to uniquely identify a client, repeater maintains a table, the table records the terminal correspondence between the identifier and the protocol version, the contents of this table can be configured. 客户端发送消息到转发器后,转发器根据终端标识取得协议版本,根据终端标识的不同进行不同的兼容处理。 The client sends a message to the transponder, the transponder is achieved in accordance with the terminal identification protocol version, compatible with different processing depending on the identifier of the terminal. 由于分离了兼容逻辑,在服务端只需保留新的服务端业务版本,通过转发器进行桥接转发,实现了协议兼容,降低了开发成本,而且由于终端标识与客户端的对应表是可配置的,升级时,对转发表进行相应地修改即可使转发器对MML命令进行不同的转换。 Due to the separation of the compatible logic, the server simply to keep the new server version of the service, bridged forwarded through the repeater, it implements the protocol compatible, reduces development costs, and because the terminal identifier and the client correspondence table is configurable, when you upgrade, to be adapted accordingly forwarding to the transponder for different conversion MML commands. 本发明允许客户端在大部分逻辑为旧业务的情况下使用新功能,实现了客户端的平滑升级。 The present invention allows the client to use the new features in the case of most of the logic for the old service, to achieve a smooth upgrade client. 除对MML命令外,本发明还适用于协议命令各字段顺序不受限制的协议,因为顺序不受限制,则不会有新旧版本因字段顺序不一致造成的不兼容。 In addition to the MML command, the present invention is also applicable to each protocol command protocol field order is not limited because the order is not limited, new and old versions because there will not be caused by inconsistent field order incompatible.
