标准范围

ISO/IEC 21989:2002规定了短消息服务(SMS)。SMS使用户能够向另一用户发送和接收短消息(SMS)。该服务基于GSM 03.40。ISO/IEC 21989:2002中描述的服务中心功能等于GSM 03.40中服务中心的功能。因此，为了与GSM网络的互操作，只需要实现QSIG接口。注1不排除与其他空中接口的互操作，但超出了本国际标准的范围。注2短消息服务是一种特殊的基本服务，但在本文档中以补充服务的形式描述。根据ETS 300 387中描述的方法，补充服务规范分三个阶段产生。ISO/IEC 21989:2002包含SMS的阶段1和阶段2规范。阶段1规范指定了PISN用户所看到的服务。阶段2规范标识了服务中涉及的功能实体以及它们之间的信息流。

ISO/IEC 21989:2002 specifies the Short Message Service (SMS).

SMS enables a user to send and receive Short Messages (SMs) to and from another user.

This service is based on GSM 03.40. The Service Centre functionality described in ISO/IEC 21989:2002 is equal to the functionality of a Service Centre in GSM 03.40. Thus, for interoperability with a GSM network, it is only necessary to implement a QSIG interface.

NOTE 1 The interworking with other air interfaces is not precluded, but is outside the scope of this International Standard.

NOTE 2 The Short Message Service is a special kind of basic service but is described in this document in the style of a supplementary service.

Supplementary service specifications are produced in three stages, according to the method described in ETS 300 387. ISO/IEC 21989:2002 contains the stage 1 and stage 2 specifications of SMS. The stage 1 specification specifies the service as seen by users of PISNs. The stage 2 specification identifies the functional entities involved in the service and the information flows between them.
