    Alcatel demonstrates IMS services over WiMAX network

    -

    Alcatel today announced that it has achieved a world first by demonstrating the delivery of IMS (IP Multimedia Subsystem) based services over a WiMAX radio access network. The objective of the demonstration was to show that the multi-access capability of Alcatel’s IMS solution can, today, be extended into the broadband wireless domain using IP WiMAX technology. The live demonstration took place at Alcatel’s premises in Vélizy, near Paris, France. Peter Jarich, principal analyst of wireless infrastructure at Current Analysis attended this world first.

    The  demonstration  utilized  key  components  of  Alcatel’s  IMS  solution connected over three different access technologies: DSL, 3G/UMTS and WiMAX. This  demonstration clearly showed  that the IMS promise of rich multimedia
    services  delivered  over  any  kind  of  access  is  now  a  reality. As a consequence,  early  WiMAX  adopters  will instantly be able to communicate with  all  of  their  friends  and  associates connected via DSL or 3G/UMTS
    worldwide.

    Through  a  dynamic  address book, the three end-users participating in the demonstration  were  able  to access their buddy lists and presence, whilst communicating  with  each  other  via  text,  voice and video communication modes.  The  demonstration  scenario  included typical IMS services such as
    community   management   functions   combined  with  audio-video  and  data messaging,  as  well  as  video  telephony, push-to-speak and push-to-show, which provided a rich IMS user experience.

    The  demonstration  validated  the robustness of the key building blocks of Alcatel’s   complete  IMS  solution,  in  particular  Alcatel’s  softswitch (Alcatel  5020  Softswitch,  including  CSCF), subscription server (Alcatel 1430  MDS,  including  HSS),  advanced SIP application server (Alcatel 5350 IAS)  and service-aware edge access node (Alcatel 7720 ABC). It also showed how  Alcatel’s  IMS solution can optimize the IP Quality of Service as well as satisfy the most stringent policy enforcement requirements.

    “WiMAX,  as  an  IP-based  network, holds a lot of promise in terms of cost efficiencies,  scalability,  etc.,”  stated  Jarich.  “At the same time, IP  opens  up  a  growing ecosystem of novel applications and IMS is the way to tap into that. Alcatel’s demonstration signals that it understands operator demands whilst helping operators to understand that IMS will be best driven by  the growth of the addressable market of IMS users beyond traditional 3G or fixed line services.”

    “By bringing together IMS-based applications and WIMAX, Alcatel is making a vision  of  the future become reality while demonstrating its leadership in delivering converged, user-centric multimedia applications over any type of
    broadband  network,”  declared  Marc  Rouanne,  chief  operating officer of Alcatel’s  mobile  communications activities. “Today’s world first IMS over WiMAX  demonstration also highlights the potential brought about by full IP
    technologies,  as  well  as  Alcatel’s ability to quickly integrate leading edge  end-to-end  solutions.  Alcatel’s  IMS  solution  is  ready to enable operators  to  deliver  user  centric  rich  communications services whilst putting more value into their networks.”

    This  demonstration  was  part  of  Alcatel’s  global  IMS  program,  whose objective  is  to provide the market with a complete open, multi-access and application-rich IMS solution that supports Alcatel’s vision of a converged fixed and mobile user-centric world.
