Combined with the application of OOD in formal specification of distributed multimedia system, a scheme building on ground of LOTOS/QTL (or Esterel/QL) and adopting the idea of OOD has been given. This method can be used to construct time model and synchronization model in distributed multimedia systems.

结合对面向对象技术在分布式多媒体的形式化描述中应用的方法分析，本文提出了一种以LOTOS/QTL或Esterel/QL为基础，融合面向对象技术的形式化描述方案，该方案可用于建立分布式多媒体系统的时间模型和同步模型。

Firstly, the basic concept and convention about formalized stand language LOTOS is introduced, and, the language was improved and extended by adding discrete time domain and time operator to confirm its syntax and semantics rules. Then, a special multimedia synchronization system and implement algorithm is proposed by anatomizing multimedia synchronization problems in distributed environment.

The invention further relates to another method of realizing welcome messages, which comprises the steps of acquiring a message indicating whether the user identification registers for a multimedia message service or not when the user identification is not the local user identification; and sending the welcome media message according to the user identification when the user identification registers for the multimedia message service.

本发明还涉及另一种实现欢迎消息的方法，当所述用户标识不是本地用户标识时，获取所述用户标识是否注册了多媒体消息服务业务的信息；当所述用户标识注册了多媒体消息服务业务时，执行根据所述用户标识发送欢迎多媒体消息。

TheAdvancestoIP Multimedia Subsystem architecture, built on the 3rd Generation Partnership Project 2 (3GPP2)'s Multimedia Domain, supports both IMS/MMD and non-Session Initiation Protocol services. In terms of network operation, A-IMS as extensions to IMS/MMD enhances the IMS/MMD network security with the addition of Security Operation Center, posture agent, etc. Some parts of the A-IMS framework are still under development sUCh as terminal support for the posture agent, security information exchange, and security policy definition.

改进的IP多媒体子系统基于3GPP2的多媒体域架构，包含了所有IP多媒体子系统/多媒体域业务功能，并增加了对非会话发起协议应用的支持；从网络运营的角度，针对IMS/MMD网络安全提出了一些扩展和补充，如增加了安全操作中心和姿态代理等，使IMS/MMD网络的安全性得到了较大改进。A-IMS仍处于框架性描述阶段，还有很多细节尚不明确，如终端对姿态代理的支持能力、安全信息交换的内容、安全策略的具体定义等，有待于进一步研究。
