ISO/IEC前言

ISO(国际标准化组织)是由各个国家标准化机构(ISC)的成员体)联合组成的一个世界性组织。该组

织通过其各个技术委员会进行国际标准的制定工作。凡是对于已设有技术委员会的某一专业感兴趣的

每一个成员体，都有权参加该技术委员会。与ISO有联系的官方和非官方国际组织也可参与国际标准

的制定工作。IS()与国际电工委员会(IEC)在电子技术标准化的所有方面都进行密切合作。

各个技术委员会提出的国际标准草案，须先分发给各成员体表决通过后，再由ISO理事会批准为

国际标准。根据ISO工作导则，国际标准至少需要投票成员体的75写赞成。

国际标准ISO/IEC10021-6是由ISO/IEC)TCI信息技术第一联合技术委员会制定的.

目前,ISO/IEC10021在信《息技术文本通信面向信报的文本交换系统》总标题下，包括以下7

个部分:

—第1部分:系统和服务概论;

—第2部分:总体结构;

—第3部分:抽象服务定义约定;

—第4部分:信报传送系统:抽象服务定义和规程;

—第5部分:信报存储器:抽象服务定义。

—第6部分:协议规范;

—第7部分:人际信报系统。

附录A和附录B是本标准的组成部分，附录C、附录D和附录E仅提供参考信息。

引言

本标准是一组面向信报的文本交换系统(MOTIS)的标准之一。

MOTIS提供用户之间基于存储一转发的信报交换。由一个用户(发方)提交的信报通过信报传送系

统(MTS)传送，并投递给一个或多个其他用户(收方)。用户可以与NITS直接交互，也可以经信报存储

器间接交互。

NITS由多个信报传送代理(MTA)组成，MTA传送信报，并将信报投递给期望的收方。

本标准由CCITT和ISO/IEC联合开发，等价的CCITT文件是CCITTX.419,

第一篇引言

1范围

本标准规定远程用户代理和NITS之间所用的MTS访问协议((P3).提供对GB/T16284.4中定义

的NITS抽象服务的访问。

本标准也规定远程用户代理和信报存储器(MS)之间所用的MS访间协议((P7).提供对

GB/T16284.5中定义的MS抽象服务的访问。

本标准还规定MTA之间所用的MTS传送协议(P1)，提供GB/T16284.4中定义的NITS分布式

操作。

GB/T16284.2标识了定义信报处理系统其他方面的其他标准。

本标准的第二篇说明MHS访问协议((P3和P7)。第6章提供MHS访问协议的概述;第7章定义

MTS访问协议((P3)的抽象语法;第8章定义MS访问协议((P7)的抽象语法;第9章定义MHS访问协

第二篇信报处理系统访问协议规范

6MHS访问协议概述

6.1MHS访问协议模型

GB/T16284.4的第6章描述信报传送系统(MTS)的抽象模型，以及MTS向MTS一用户提供的

MTS抽象服务。

GB/T16284.5的第6章描述信报存储器(MS)的抽象模型，以及MS向MS一用户提供的MS抽象

服务。

本章描述抽象服务的用户和抽象服务的提供者作为分布在不同开放系统中的应用进程来实现时，

如何由OSI通信的实例来支侍MTS抽象服务和MS抽象服务。

在OSI环境中，应用进程之间的通信用表示服务的一对应用实体AE之间的通信来表示。应用实体

的功能被细化成一组一个或多个应用服务元素(ASE),AE之间的交互通过使用ASE提供的服务来描

述。

有三种应用服务元素支持对MTS抽象服务的访问，每一种都支持抽象模型中MTS用户和MTS

之间配对的一种端口类型.信报提交服务元素(MSSE)支持提交端口的服务;信报投递服务元素

(MDSE)支持投递端口的服务，信报管理服务元素(MASE)支持管理端口的服务;MSSE,MDSE和

MASE是非对称的ASE，即MTS用户ASE和MTSASE分别作为MTS抽象服务的顾客和提供者。

类似的.有三种应用服务元素支持MS抽象服务的访问，信报提交服务元素(MSSE)支持间接提交

端口，信报索取服务元素(MRSE)支持索取端
