本技术规范旨在介绍移动系统的可能架构。本规范第3条包含支持移动服务所需的不同功能实体的定义。在第4条中，描述了PLMN的配置以及功能实体的组织；为了应对在不同国家可以想象的所有可能的实现，本文介绍的配置是最通用的。为了说明这一目的，本文给出了一些可能的配置示例。 本规范第5条对涉及的接口进行了简要说明，说明了所考虑组织的原则。

The purpose of this Technical Specification is to present the possible architectures of the mobile system. Clause 3 of this specification contains a definition of the different functional entities needed to support the mobile service. In clause 4, the configuration of a PLMN is described as well as the organisation of the functional entities; the configuration presented is the most general in order to cope with all the possible implementations which can be imagined in the different countries. To illustrate that purpose, some examples of possible configurations are presented. Clause 5 of this specification contains a brief description of the interfaces involved which shows the principle of the organisation considered.
