FutureComm 2010: LTE and RCS FutureComm 2010: LTE and RCS Presentation Transcript

  • Sagi Subocki
    Products Manager,
    Head of IMS Segment
    October 2010
    LTE – The Future of IMSRCS – Advanced Interoperable Services
  • Agenda
    Introduction to LTE
    The VoLTE initiative
    LTE and IMS
    RADVISION IMS Development solution
    Rich Communication Suite
    RADVISION RCS Developer Solutions
  • LTE - Introduction
    LTE (Long Term Evolution) – foundation of 4G
    All IP and Higher Bandwidth, low latency.
    Enhances existing 3G UMTS
    Efficiently supports multi-antenna technologies (MIMO).
    High bandwidth—up to 20 MHz.
    Scalable, LTE can operate in the existing 5-MHz UMTS frequency bands, or in even smaller bands.
  • LTE – the end of Circuit Switch
    LTE is an all-IP mobile network
    No support for ‘traditional’ CS domain voice
    New Voice and SMS solutions required
  • The future of operators
    Top 25 LTE Operators Will Reach Over 200 million LTE Subscribers by 2015 
    CAPEX spending to reach $14 billion in 2015
    - Maravedis research
  • Operators today face real challenges
    Future of  voice service usage:
    Migration of customers towards mobile
    VoIP solutions over their data networks
    The App Store:
    Services that run on the network are
    not controlled by the network operator.
    LTE:
    All about IP connectivity. Need a solution for
    traditional voice and SMS services.
    Significantly improves network's quality – operators are becoming "dumb" data pipes
    Operators need to be able to provide new services and stay relevant!
  • The Solution - IMS
    The enabler for operators to continue to be the service provider of all services over LTE.
    Reliable, QoS, Secure,
    Service Continuity, Roaming.
    IMS will materialize –
    the operators simply have
    no other choice.
  • VoLTE - Voice over LTE
    IMS profile
    Started as “One Voice”
    Initiative of 18 operators and handset vendors
    GSMA adopted it
    Work continues on the initial “One Voice” draft
    Renamed to “VoLTE”
    IMTC IMS Activity Group was selected by “OneVoice” initiative to develop VoLTE test specification.
  • VoLTE - Introduction
    VoLTE profile defines a minimum mandatory set of features in order to guarantee an interoperable, high quality IMS-based telephony service over LTE access networks
    Voice and SMS in first stage - fast to fight new options for mobile VoIP
    “smart pipe” vs “dumb pipe”

  • How Will Networks Migrate to LTE?
    Networks will not switch overnight from GSM and 3G to LTE.
    Operators will need to provide service continuity
    VCC = Voice Call Continuity
    SMS
    Need to integrate new technologies to stay relevant
    Operators making the move with different approaches.
  • IMS - Introduction
    IP Multimedia Subsystem
    Designed to provide flexible multimedia services anytime and everywhere
    Part of the core network, with interfaces to other subsystems in the network
    Technical specifications by GPP/3GPP2/TISPAN/Packet Cable and others
    Enables to ensure secure, reliable, interoperable, roamed, services with QoS
  • How?
    An architecture for IP based next generation service and call control
    Layered, functional architecture
    Open application development framework
    Common authentication, authorization and accounting framework
    Common media control and network management functions
    An architecture that will be used in all networks
    Cellular
    Fixed carrier networks
    WiMax networks
    Packet Cable networks
    LTE
  • IMS is happening now!
    By 2011 80% of surveyed service providers will run voice over IMS (Infonetics).
    Common IMS – Adopted by Cellular (3GPP/3GPP2), LTE, Fixed Line (TISPAN), Cable (PacketCable 2.0), and WiMAX
    A wide basic set of IMS standards which are identical to all networks.
    Each access network has its own unique "flavor" added on top of it.
  • Key to IMS Application Success
    Compliancy to the standards
    Ensures interoperability
    Easy deployment
    “Worry-free” roaming
    Smooth evolution to IMS SIP
    Ability to add new IMS Services
  • IMS Compliancy Challenges
    Many new network entities
    Many new protocol requirements
    New interfaces
    Different access networks each behaving differently – Cellular, Wireless, Fixed Line, Cable, LTE, WiMAX
    New standards constantly added upon and revised
  • New Services in IMS Release 9
