             IP Multimedia in Next Generation Mobile Networks:
                    Services, Protocols and Technologies
   
           Special Issue of IEEE Personal Communications Magazine


   One of the most exiting and challenging aspects of next generation
   mobile networks is the provision of IP Multimedia services, similar to
   those recently emerged on the Internet. Currently, both in commercial
   and academic arenas, a great effort is under way to develop, test and
   standardize, the technologies that would enable the efficient, secure
   and cost-acceptable provision of IP Multimedia services in the next
   generation mobile networks. Such services would ultimately migrate the
   Internet to the wireless world and would satisfy the demand for
   sophisticated, valuable and user-friendly wireless IP services.

   Doubtless, the advanced radio technology of third-generation (3G)
   systems is the leading technology that paved the way to the mobile
   multimedia era. However, the advanced radio technology alone is not
   sufficient to provide true multimedia services. In fact, when
   considering a mobile IP multimedia system, the radio technology is an
   important but, yet, a small part of the entire system. Other enabling
   technologies, such as, session management protocols, confidentiality
   and integrity protection schemes, end-to-end quality of service (QoS),
   traffic management, service control platforms, billing, etc. are also
   crucial components of a mobile IP multimedia system. This special
   issue is devoted to these components and aims at providing a
   comprehensive review of their recent and emerging development. In
   general, the main objective of this special issue is to address the
   Protocols and Technologies used in next generation mobile networks for
   enabling the IP Multimedia services. Additionally, the Services
   themselves will be considered. In this context, papers are solicited
   reporting on representative topics, such as:
     * IP Multimedia Services on next generation mobile networks (such as
       VoIP)
     * Challenges and solutions for IP Multimedia services on next
       generation mobile networks
     * Architectures for IP Multimedia services on next generation mobile
       networks
     * IP Multimedia protocols (e.g. SIP, RTP, RTCP) and their deployment
       in mobile networks
     * Techniques for improving the efficiency of multimedia protocols in
       wireless environments
     * Interworking with the Internet and other multimedia architectures
       (such as H.324, H.321)
     * Interworking with legacy networks (such as PSTN, ISDN, GSM, etc)
     * Techniques for provisioning of QoS
     * Security threads and techniques for security provision
     * Service control platforms and interfaces
     * Video and metadata encoding schemes for wireless multimedia
     * Wireless multimedia applications
     * Standardization activities
     * Performance studies

   All submissions should adhere to the style of IEEE Personal
   Communications Magazine. Guidelines for prospective authors can be
