Abstract [en]

In the future, mobile users will have the possibility to use a variety of wireless access networks simultaneously making the vision "Always best connected" come true. The Internet Protocol (IP) will most likely be the least common divisor allowing service providers to deploy services in a unified way regardless of access network type (being wired or wireless). The 3GPP-led development of the IP Multimedia Subsystem (IMS) is a promising step towards the vision. However, there are a number of obstacles along this way forward. Various deployment difficulties related to already installed base of user and infrastructure equipment and service providers protecting their old investments are the most common obstacles. In addition to those reasons, somewhat conservative regulatory authorities, short-comings in digital rights management, multiple standardization bodies proposing non-aligned solutions, as well as non-uniformed and non-optimized use of radio spectrum do not improve the speed of change.Our research is performed within the area of seamless real-time multimedia distribution in heterogeneous wireless access networks with a user-centric and end-to-end system approach. Having proposed various extensions to Mobile IP (MIP) including multihoming and port-based handling of flows, as well as solutions for global connectivity in ad hoc networks we now present a combined architecture using both MIP and Session Initiation Protocol (SIP) for mobility management where MIP is used for TCP connections and SIP is used for UDP traffic carrying real-time multimedia streams of data.
