  1. GSM-on-the-Netand FMC issues Lill Kristiansen based partly on paper from Ericsson review 1998 http://www.item.ntnu.no/~lillk/docs/gsm-on-the-net-1998046.pdf and partly on own work at Ericsson 1998-2001, GSM-on-the-Net viewed in 1998 and in 2007

  2. 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. GSM-on-the-Net viewed in 1998 and in 2007

  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.) GSM-on-the-Net viewed in 1998 and in 2007

  4. Evolution of IP Telephony to MultimediaPlayers, market Mobility/Wireless Integration Next Generation Converged Networks Integrated Services Data/Voice Integration /Multimedia Basic Voice Low-cost telephony /Mobile GSM-on-the-Net viewed in 1998 and in 2007

  5. 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. GSM-on-the-Net viewed in 1998 and in 2007

  6. ”Future proof” • The PBX market is changing rapidly, however, and sooner or later today’s 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”) GSM-on-the-Net viewed in 1998 and in 2007

  7. user and terminal mobility • Terminal mobility • A terminal can be moved around geographicallywithout 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 terminal’s capabilities. • (Registration via PC is not by using the SIM-card) GSM-on-the-Net viewed in 1998 and in 2007

  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 ”3+G” (3G-All-IP) is the new core ”3+G 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 viewed in 1998 and in 2007

  9. GSM on the Net: one user, several phones From Ericsson Review No 04, 1998 http://www.ericsson.se/review/pdf/1998046.pdf GSM-on-the-Net viewed in 1998 and in 2007

  10. A user’s 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.” ”Service architecture” GSM-on-the-Net viewed in 1998 and in 2007

  11. System topology - Next generation networks • Today • Separate Networks • Separate Users • Separate Services • Tomorrow • Separate Accesses • Same Core network • Same User on different accesses • Same Services Separate Services PLMN Data/IP Networks PSTN/ISDN CATV Separate users GSM-on-the-Net viewed in 1998 and in 2007

  12. System topology - Next generation networks • Today • Separate Networks • Separate Users • Separate Services • Tomorrow • Separate Accesses • Same Core network • Same User on different accesses • Same Services Servers Content Content Communication Control Access Gateways Access Gateways Backbone Network Access Access Access Users GSM-on-the-Net viewed in 1998 and in 2007

  13. Services User/subscriber database Home GK 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 GK I/f Registration via visiting GK to home GK Visited GK GSM-on-the-Net viewed in 1998 and in 2007

  14. For the operator, GSM on the Net offers: increased GSM traffic—new subscribers and lower churn Furthermore, the business user’s behavior pattern, in terms of calling frequency and call duration, will transfer to global use as well; profit margins—if supplied by the operator, system equipment (servers and phones) will boost profit margins through increased product sales and more service agreements; new services—the 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 work—the same “look and feel” wherever the system is accessed (whether the user is in the office, at a subsidiary, at home, or traveling); convenience—having 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-effectiveness—implementation 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); adaptability—the 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; scalability—flexible service and application design (server applications), easy-to-add base stations and handsets.

  15. More on business • GSM radio frequency is licenced • GSM operator stay in the value chain • Later: • Ratate this business chain with e.g. OBAN GSM-on-the-Net viewed in 1998 and in 2007

  16. Deployment • How to make ”boxes” out of the logical architecture • taking scalability and more into account GSM-on-the-Net viewed in 1998 and in 2007

  18. Large-company solution GSM-on-the-Net viewed in 1998 and in 2007

  19. ”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 • A research paper from 2002 (by Ericsson people): • Sharareh, A., Matteo, G., and Gianluca, T. 2002. Quantitative analysys for telecom/datacom software architecture. In Proceedings of the 3rd international Workshop on Software and Performance (Rome, Italy, July 24 - 26, 2002). WOSP '02.
