  s0 {. @) x. uIMS (IP Multimedia Subsystem) 是原本由3rd Generation Partnership Project (3GPP)所制定做為3G WCDMA 行動通訊的標準，但目前已經被3GPP2 (CDMA2000 網路) 及ETSI TISPAN (固接網路) 採為標準，ITU-T 亦將IMS 納為NGN 的標準，IMS 將會成為未來整合Internet、PSTN、Wireless 與xDSL 各種異質網路的服務控制平台，而IMS-based 的服務將以高度個人化的形式提供包含語音、文字、圖片和影像等任意組合的多媒體應用。
應用領域
各種IP 連線接取網路 (IP-CAN)網路及通訊設備系統中，使用者設備(User Equipment, UE)的註冊、Call Session 的建立與管理，以及各類型應用服務的觸發如OSA/Parlay Applications、IM Applications 及SIP Applications各種IP 連線接取網路 (IP-CAN)網路及通訊設備系統中，使用者設備(User Equipment, UE)的註冊、Call Session 的建立與管理，以及各類型應用服務的觸發如OSA/Parlay Applications、IM Applications 及SIP Applications
