TOPS COUNCIL

• Chair Bill Smith, Chief Product Development
  Technology Officer, BellSouth Telecommunications
• The TOPS Council identified sixteen (16) industry
  priorities five of which were deemed critical
• Mobile Wireless Services (MWS)
• Voice over Internet Protocol (VoIP)
• Wide Area Ethernet (WAE)
• Security Issues (Security)
• Data Interchange (DI)
• The TOPS Council established expert Focus Groups
  for each critical priority to determine
• where industry standards are needed to address
  these priorities
• where efficiencies can be gained in the
  standardization processes

MWS FG Work Program

• Examine and comprehensively define assigned
  priority (Mobile Wireless Services)
• Flesh out its underlying issues
• Identify technical and operational component
  work-programs currently working on convergence
  issues for Mobile Wireless Services
• From the information collected
• Establish a work-plan assessing key aspects of
  MWS
• Determine the best SDO work-programs to continue
  efforts
• Set milestones and timelines to complete
  standardization work
• Where items are not being addressed in existing
  standards work, recommend initiating necessary
  work-programs in a specific standards developer
• Where overlaps and redundancies are discovered,
  recommend the focusing of industrys limited
  resources in the most appropriate standards and
  corresponding standards bodies

Mobile Wireless Servicesand Convergence

• End users want their familiar, personalized
  services, regardless of how they access the mode
  of communications.
• End user expectations results in a requirement
  that services offer the same touch and feel
  regardless of access method.
• End user gains a comfort level supported by
  consistent security, QoS, reliability,,,,,,etc.

6
How to reach the user Comfort Level?

• This user Comfort Level can only be fulfilled
  through convergence of wireline, PCS/cellular and
  WiFi networks and services
• Convergence in terms of interoperability of
  networks, in terms of various core services and
  in terms of network attributes (such as AAA,
  security, QoS, service management and control,
  reliability, regulatory requirements, etc.)

One Network View

• The User-centric Experience

8
Assessment (Overview)

• One Network View
• Focus is needed on standardization of seamless
  features and services across wireline, cellular
  and WiFi networks
• Specific recommendations are needed regarding
  architectures and protocols
• Initial concentration of efforts are important in
  two major service categories
• Voice
• Presence/Messaging
• Expected Outcome
• Industry support and execution of identified
  elements and recommended actions should allow
  for, Carrier Grade converged feature and
  service solutions.

Network Differentiators
The one-network (the converged-network)
perspective must find a way to accommodate the
different expectations associated with different
networks.
10
Convergence Observations

• Momentum among SDOs for convergence within the
  wireless domain is apparent.
• Key developers working within this space such as
  3rd Generation Partnership Project (3GPP), 3GPP2,
  ITU-T, and Open Mobile Alliance (OMA) have
  created liaisons and transferred certain efforts
  across groups to coordinate appropriate
  work-programs
• The path of convergence for the interconnection
  of common services regardless of interface
  technology or infrastructure is not so apparent,
  but is essential

11
Convergence Recommendation

• To forge convergence between wireline and
  wireless platforms
• work needs to start immediately within a NGN
  forum/group with a global perspective -- such as
  a Partnership Project, a Joint Experts Group or
  the ITU.
• ATIS should play a leading role in the
  establishment of this group.
• ATIS (and its committees such as T1S1 T1P1)
  should support and monitor the work of this new
  group

12
Voice Services

• Voice is the baseline service for convergence
• Key Voice Services Recommendations
• The IMS model developed within 3GPP should be the
  basis for future wireline/wireless convergence
  work and ATIS should support 3GPP in the
  development of modifications and extensions to
  achieve convergence
• Protocol extensions to SIP should continue within
  the IETF. ATIS committees should serve to
  expedite IETF acceptance of relevant IETF Drafts

13
Presence

• It is useful to be able to determine the status
  and /or availability of a particular party prior
  attempting to establishing communications with
  that party

14
Presence - An Enabler for Convergence of Advanced
Services

• Presence enhances user productivity
• To be most useful, presence and presence-enabled
  services require a common look and feel and thus
  a need for convergence across networks
• Presence with Preference enables services such as
  Instant Messaging, Instant Voice, Instant Video,
  Instant Conference, Instant Notification.
• The real value of these services will be realized
  when they are offered in a bundle and integrated
  with other advanced applications yet to be
  developed over a converged network

Presence Recommendation

• Industry adopt SIP/SIMPLE as a primary mechanism
  for management Presence information
• It is also proposed to support SIP/SIMPLE as the
  primary means to support Presence across networks
  (i.e. as the inter-carrier Presence protocol)

17
Next Steps

• Next Steps
• Finalize recommended actions necessary to provide
  industry with a roadmap towards network
  convergence
• Establish meaningful working relationships with
  industrys standards developers (world-wide) to
  move critical work-programs forward
• Monitor the progress of industrys work-programs
  and its resolution of recommended actions
• Provide appropriate support to achieve
  implementable, end-to-end standards and solutions
  towards network convergence.
