GSM-on-the-Net and FMC issues

GSM-on-the-Netand FMC issues

• Lill Kristiansen
• based partly on paper from Ericsson review 1998

  -1998046.pdf
• and partly on own work at Ericsson 1998-2001,

Background

• from the paper
• The handling and sharing of information is of
  vital importance to the business world.
• To this end, many companies have installed a
  local area network (LAN) to make in-house
  networking and communication more efficient.
• Internet/intranet, e-mail and databases are a few
  examples of applications and entities accessible
  from a LAN.

3
Why? in 1998

• IP-telephone was emerging (mostly on PCs)
• VoIP but also shared applic. video
• Ericsson strong position in public GSM
• wanted the GSM-UMTS-track to continue
• GSM-on-the-net was targeted towards the
  enterprise market
• intergration/convergence with databases (address
  books, customer relations etc.)

Former technology for enterprises

• In DECT, all user services reside in the PBX,
  while all wireless-related services (for example,
  roaming and handover) are handled by a mobility
  server.
• In the case of GSM, new features are introduced
  in the macro network in order to support typical
  office services. (proffnett etc.)
• For example, home zones make it possible to
  distinguish between external calls and calls made
  in the office virtual private networks (VPN)
  support private numbering plans.

6
Future proof

• The PBX market is changing rapidly, however, and
  sooner or later todays solutions, which are
  based on proprietary hardware and a
  circuit-switched environment, will be replaced by
  PBXs operating according to the Internet protocol
  (IP).
• Clearly, therefore, a sustainable, long-term
  solution for GSM in the office will have to be
  based on IP. (future proof)

7
user and terminal mobility

• Terminal mobility
• A terminal can be moved around geographicallywitho
  ut losing contact with the system.
• User mobility
• A user can opt to access GSM on the Net
  indifferent ways.
• Regardless of whether a phone or a PC is chosen
  as a means of access, the system will keep track
  of the user and the terminals capabilities.
• (Registration via PC is not by using the
  SIM-card)

8
FMC several generations

• Steinara pketches a solution to add a SIMcard
  reader to add fixed phones to integrate with GSM
• This will make fixed voice an access technology
  into GSM
• GSM will be the core system
• we can call this 2G FMC
• No so in GSM-on-the-Net! There a new generation
  of services 3G (3G-All-IP) is the new core
  3G FMC
• access antagonistic system
• Core system is future proof IP allowing for MMoIP
  / XoIP (anything over IP),
• today partly called VVoIP
• PSTN, GSM, LAN are all access technologies
• each with some restrictions
• GSM good mobility but not VVoIP
• PC XoIP and good UI, but only nomadic mobility
  (unless WLAN with handover support is added as
  well)
• Issue session handover, in particular from IP to
  the GSM-part
• If GSM-on-the-Net is deployed publicly Then it
  is IMS (and 2G GSM may play a smaller part in the
  system over time)

GSM on the Net one user, several phones

Service architecture

• A users service profile is stored in the service
  node, not in each type of access. (access
  antagonistic)
• This means that all specified services are
  available to users, no matter what type of
  terminal they use to access the system.
• Keeping track of terminal capabilities that may
  limit this.
• However, the man-machine interface or
  limitations in bandwidth in the chosen access may
  reduce or inhibit the use of some services.

Virtual Home Environment (input to ETSI Tiphon)

• The user may log on from anywhere
• Visited GK control his own resource
• The visited GK contact home GK and routes the
  call (but not necessarily the media) via the home

Benitif box (selling arguments)

• For the operator, GSM on the Net offers
• increased GSM trafficnew subscribers and lower
  churn
• Furthermore, the business users behavior
  pattern, in terms of calling frequency and call
  duration, will transfer to global use as well
• profit marginsif supplied by the operator,
  system equipment (servers and phones) will boost
  profit margins through increased product sales
  and more service agreements
• new servicesthe provision of convergence
  services will generate more revenue.
• Examples include service packages, which can be
  tailored to suit individual organizations and
  vertical market applications.

• For the user enterprise mainly, end-users
  partly, GSM on the Net offers
• freedom at workthe same look and feel wherever
  the system is accessed (whether the user is in
  the office, at a subsidiary, at home, or
  traveling)
• conveniencehaving GSM integrated into the office
  gives the convenience of one phone and one
  number. The same phone is used, regardless of
  user whereabouts, within or outside of the
  office
• cost-effectivenessimplementation costs are low
  because existing PCs and LANs are used.
  Similarly, operation costs are low thanks to
  low-tariff, local traffic (through local
  switching) differentiated user authorization
  available resources for administration (for
  example, the IT support team) adaptabilitythe
  system is a smoothly fitting part of the existing
  network environment (and applications) and can
  easily be expanded and improved with respect to
  capacity, functional content, and quality
• scalabilityflexible service and application
  design (server applications), easy-to-add base
  stations and handsets.

More on business

• GSM radio frequency is licenced
• GSM operator stay in the value chain
• Later
• Ratate this business chain with e.g. OBAN

Deployment

• How to make boxes out of the logical
  architecture
• taking scalability and more into account

PS postscript

• Many press releases around 98-2000 about the
  system (trials around the world).
• No press release to close down the system (such
  press releases normally are not produced)
• Architecture went into IMS
