services
Services
  • ALL 3GPP IMS Services
  • Plus
    • Emergency calling (112 etc.)
      • for all terminals/users
    • Existing PSTN/ISDN services
      • for legacy only
    • Interoperability with 3GPP IMS
    • Interworking to PSTN/ISDN
      • both TDM and replacement scenario
    • Future Services e.g. streaming (RTSP)
      • e.g. Video on Demand, broadcast services

system components
System Components
  • Customer Networks & Terminals
    • Diverse Customer Networks supporting multiple diverse terminals
    • “shared terminal use” as well as exclusive
  • Access Networks
    • re-using existing deployments
      • xDS,LWireless Lan, Corporate Lan, cable networks, 3GPP GPRS
  • Core Network
    • IP Based transport network + IMS
  • Interconnect

constraints
Constraints
  • Existing Customer Networks
    • Hubs, Routers, WLAN
  • Existing Customer Terminals
    • PC’s; PDA’s; Phones;
    • lack of regulation & diversity
  • Access Networks already deployed
    • xDSL, backhaul to ISP’s; V5 fibre
    • Concentrators, multiplexors
  • Core Network
    • 3GPP IMS based, minimal changes
  • Interconnect
    • other NGN; 3GPP IMS; Internet; PSTN/ISDN

TISPAN-3GPP Workshop - Sophia-Antipolis

requirements overview 1
Requirements Overview 1
  • All 3GPP IMS services;
    • extended/adapted for fixed-line terminals;
  • Conversational and non conversational services;
  • Support for existing PSTN/ISDN terminals;
    • partial or wholesale replacement of existing core infrastructure;
  • Regulatory Requirements
    • e.g. Emergency calling from any access;
  • Interworking at the NNI;
  • Mobility: nomadicity of users and devices;

TISPAN-3GPP Workshop - Sophia-Antipolis

requirements overview 2
Requirements Overview 2
  • Secure and trustworthy environment;
  • Support for a wide range of QoS-enabled services;
  • Managed network
    • high availability;
  • Flexible framework
    • service innovation & standardisation minimal;
  • Third party service provider support;
  • Flexibility
    • to support an ever-increasing variety of terminals with diverse capabilities.

TISPAN-3GPP Workshop - Sophia-Antipolis

mobility
Mobility
  • User Mobility
    • Moving to different physical locations and using a terminal
    • Requires unique identity
  • Terminal Mobility
    • the ability to move to different physical locations and provide the user with their services
  • Authentication
    • User Authentication (by core) for services
      • Identification of user
    • Terminal Authentication (by access network) for connectivity
      • Device capabilities

TISPAN-3GPP Workshop - Sophia-Antipolis

pstn isdn replacement
PSTN/ISDN Replacement
  • Supporting Existing Customers and Equipment
    • including existing access
  • Maximum common equipment
  • PSTN/ISDN Services ONLY
    • But interoperable with IMS (voice) services
  • Interconnect to existing (TDM-based) PSTN/ISDN
    • for all NGN customers (voice only)

TISPAN-3GPP Workshop - Sophia-Antipolis

pstn isdn service re use
PSTN/ISDN Service Re-use

(PSTN/ISDN Simulation)

  • NGN Customers
    • Existing (similar) services
      • divert, voice mailbox, “CLI” etc.
    • Not Identical to PSTN
    • Different invocation/ergonomics
      • To take advantage of new network and terminal capabilities
  • True PSTN/ISDN Services
    • Not available, but interworked.

TISPAN-3GPP Workshop - Sophia-Antipolis
