[中文适用范围]： 此服务定义符合 [1] 标准。它定义了一种服务类型，本文称为消息服务。消息服务是一种 UPnP 服务，允许控制点使用电话服务器 (TS) 或电话客户端 (TC) 提供的消息功能。它在 UPnP 网络中提供电话（例如智能手机、IP 电话、VoIP 网关等）的全部消息功能，并充当 TS。此外，或者作为替代方案，充当 TC 的设备可以通过 UPnP 电话提供消息服务。此服务为控制点提供以下功能：页面模式消息（例如电子邮件、短信、彩信等）：通知收到消息、阅读消息、发送消息、删除消息。会话模式消息（例如即时消息、短信等）：通知收到消息、在会话中检索和发送消息、创建、修改或关闭消息会话。文件传输会话，用于近乎实时地传输文件。此服务不提供以下功能：连接到远程服务器以发送或接收消息（例如，WAN 端）；向最终用户呈现消息通知和消息；配置消息服务帐户以连接到远程服务器； [外文原描述]： ISO/IEC 29341-26-12:2017 is compliant with [1]. It defines a service type referred to herein as Messaging service. The Messaging service is a UPnP service that allows control points to use the messaging features provided by a Telephony Server (TS) or a Telephony Client (TC). It provides in the UPnP network the overall set of messaging capabilities of a phone (e.g., smartphone, IP phone, VoIP gateway, etc.), as the role of a TS. Additionally, or as an alternative, a device with the role of a TC can provide the Messaging service via UPnP Telephony. This service provides the control points with the following functionalities: - Page Mode Messaging (e.g., e-Mail, SMS, MMS, etc.): notification of incoming messages, reading messages, sending a message, deleting a message. - Session Mode Messaging (e.g., Instant Messaging, SMS, etc.): notification of incoming messages, retrieving and sending the messages within a session, creating, modifying or closing a messaging session. - File transfer session, to transfer the files in near real time. This service does not provide the following functionalities: - Connection to a remote server for sending or receiving the messages (e.g., WAN side); - Rendering of message notifications and messages to the end user; - Configuring the Messaging service with account for connecting to remote servers;
