Access IP Multimedia Services
The IMS (IP Multimedia Subsystem) is the future §trend that will merge the Internet with the cellular §world. However, a majority of legacy devices today §and future lack coherent support for next generation §networked multimedia services. The goal of this book §is to find a way to access IMS services for non-IMS §devices, especially for the mobile phone devices. In §this book, we proposed a browser-based IMS System §Architecture for the non-IMS devices to access IMS §services. The system architecture mainly focuses on §portable non-IMS devices, but it is also compatible §with fixed devices. Besides, we also proposed §several technical solutions to the problems in §security, provisioning, identity management, inter-§working, and device management. To evaluate the §architecture we implemented three IMS use cases: IMS §Registration, Presence service, and Page mode §Instant Message. Based on the testing result, we §validate the possibility of the system architecture. §The work also outlines a roadmap for future §potential works and system extensions.
