Further partition of each layer as well as control flow of the system is presented afterwards . considered one of the most important parts of the dissertation , specification and implementation of two application - oriented protocols , called the nrdp ( network related dialogue request protocol ) and nakp ( network related protocol between layer a and k ) were discussed in detail 在對zhx - ums的服務調度分析部分中,劃分了a 、 k層各功能模塊,分析zhx - ums服務調度中各個功能模塊的調用關系,并且定義了該系統的服務調度控制流程和服務調度狀態機。
Based on the description of main functions and relationships among the layers , the author aimed at voice information related protocols through the interface of pstn in ums , and proposed to supply ums service by two application - oriented protocols , called the trdp ( telephone related dialogue request protocol ) and the takp ( telephone related protocol between layer a and k ) . in this project , the author was mainly involved in specification and implementation of the trdp and the takp 通過對各層的主要功能及層間關系的描述,針對ums涉及的pstn接口中的語音類信息,提出通過trdp (服務請求對話協議, telephonerelateddialoguerequestprotocol )和takp (輔助層與核心層間的通信協議, telephonerelatedprotocolbetweenlayeraandk )這兩個專用應用協議來實現ums對電話類終端的服務。
