摘要

隨著行動通訊網路技術的快速發展，人們透過智慧型行動裝置能夠隨時隨地的享用網路上各式的服務。在整合多元的網路環境的次世代網路（Next Generation Network；NGN）中，以All-IP 網路為基礎架構的IP多媒體子系統（IP Multimedia Subsystem；IMS）是多媒體應用服務的整合平台。同時物聯網時代的來臨，人們生活周遭存在了許多具連網功能與多媒體處理能力的設備。使用者想透過擁有的設備享用IMS相關服務，但如果這些設備未裝置USIM（UMTS Subscriber Identity Module）卡是無法享用IMS平台之相關的多媒體服務。以通話為例，於撥打/接聽電話時，只侷限於具有USIM卡的智慧型行動裝置能夠使用。無法將此通話隨著使用者的移動，轉移至使用者的所在地，並依照使用者的個人喜好，而隨心所欲地轉換參與通話的設備。為了解決IMS通話服務，能夠接續在IMS設備與非IMS設備之間的問題，本論文基於在用戶管理網域中，設置Gateway的方式，來協助IMS設備與非IMS設備建立媒體會談與會談轉移，以達到「IMS設備與非IMS設備會談移動」。

With the rapid development of mobile communication network technology, people can receive various services on the network anytime and anywhere through smart mobile devices. In the Next Generation Network (NGN), the IP Multimedia Subsystem (IMS) based on the All-IP network is an integrated platform for multimedia application services. At the same time, the advent of the Internet of Things has created many devices with capabilities of networking and multimedia processing around people’s lives. Users want to enjoy IMS-related services through their devices, but these devices do not equip with a UMTS Subscriber Identity Module (USIM) card, so they cannot enjoy the multimedia services related to the IMS platform. Taking a voice call service as an example, when dial/ answer a call, it can only be used by a smart mobile device with a USIM card. It is not possible to transfer this call to other user’s devices without a USIM card. To solve the IMS call service and continue the issues between IMS devices and none-IMS devices. To achieve “Session Mobility between IP multimedia Subsystem Devices and Non-IP Multimedia Subsystem Devices”, this thesis adopts a Gateway-based method for media session establish and session transfer on IMS devices and non-IMS devices.
