2. AG Projects NGN Signaling Forum - 2006 Telecom Signaling Networks and Service Forum January 17, 2006 Amsterdam

3. AG Projects NGN Signaling Forum - 2006 I am a bachelor of electrical engineering Member of ETSI ENUM task force Member of management board of OpenSER project Co-chair of ISOC NL SIP Working group Founder of AG Projects I am Adrian Georgescu

4. AG Projects NGN Signaling Forum - 2006 AG Projects delivers simple SIP and ENUM solutions that delivers today what IMS promises it will deliver tomorrow

5. AG Projects NGN Signaling Forum - 2006 The opinions expressed in this presentation belong to myself, my company and most of my friends

6. AG Projects NGN Signaling Forum - 2006 Numbering and addressing in NGN Business models around ENUM

7. AG Projects NGN Signaling Forum - 2006 For those who don't know NGN is the Internet

8. AG Projects NGN Signaling Forum - 2006 Even if you dont agree with it

9. AG Projects NGN Signaling Forum - 2006 All IP means the Internet full stop.

10. AG Projects NGN Signaling Forum - 2006 From the old PSTN ONLY the E.164 numbering plan remains

11. AG Projects NGN Signaling Forum - 2006 SS7, ISDN, MTP, SCP, SP, TCAP, ISUP, MAP, IN all go away

12. AG Projects NGN Signaling Forum - 2006 And you migrate to all IP, SIP based communications

13. AG Projects NGN Signaling Forum - 2006 Using the big, bad, ugly Internet

14. AG Projects NGN Signaling Forum - 2006 No QoS, no guarantee, no central control, no regulation, no monopoly

15. AG Projects NGN Signaling Forum - 2006 Internet, a dumb network Its role is merely to deliver packets from A to B

16. AG Projects NGN Signaling Forum - 2006 The services (applications) are performed at the edge and not in the center

17. AG Projects NGN Signaling Forum - 2006 DNS is the only centralized resource on the Internet

18. AG Projects NGN Signaling Forum - 2006 DNS (Domain Name System) provides naming and addressing for the Internet

19. AG Projects NGN Signaling Forum - 2006 Internet is different than the PSTN

20. AG Projects NGN Signaling Forum - 2006 In PSTN the intelligence is at the center and the end- device is dumb

21. AG Projects NGN Signaling Forum - 2006 This why you still get only voice after 100 years of innovations

22. AG Projects NGN Signaling Forum - 2006 0800, 0900, prepaid, IVR all together is just one application: VOICE

23. AG Projects NGN Signaling Forum - 2006 On the Internet voice is just another application

24. AG Projects NGN Signaling Forum - 2006 Dont negate it, on you laptops you have more then voice

25. AG Projects NGN Signaling Forum - 2006 Do you use SIP today?

26. AG Projects NGN Signaling Forum - 2006 Because of the laptop software policy of your employer it could be that you never experienced voice over IP

27. AG Projects NGN Signaling Forum - 2006 Not knowing how Internet works, is an ingredient of going bankrupt

28. AG Projects NGN Signaling Forum - 2006 Internet is based on the end-to-end principle, all services may be offered anywhere and can be accessed from everywhere

29. AG Projects NGN Signaling Forum - 2006 In Internet you have connectivity and applications

30. AG Projects NGN Signaling Forum - 2006 Voice is just another application

31. AG Projects NGN Signaling Forum - 2006 Next to email, web and others

32. AG Projects NGN Signaling Forum - 2006 Voice and other communications do not need a service provider at all, they are applications. –Jon Peterson, ITU-IETF NGN Workshop, Geneva, May 2005

33. AG Projects NGN Signaling Forum - 2006 Actually, there is plenty to do for an operator if you dont clutch at penny per minute anymore

34. AG Projects NGN Signaling Forum - 2006 Replace your marketing department and you will see how competitive and innovative you become

35. AG Projects NGN Signaling Forum - 2006 Internet intelligence is at the edge, this opens the competition with any new entrant

36. AG Projects NGN Signaling Forum - 2006 You most important technical assets today (your signaling point presence on the SS7 network) is not anymore a critical advantage

37. AG Projects NGN Signaling Forum - 2006 Today some work hard on copying PSTN concepts over an Internet infrastructure

38. AG Projects NGN Signaling Forum - 2006 IMS is an example of such concept

39. AG Projects NGN Signaling Forum - 2006 Technically complicated, appealing for decision makers who still try to lock users in a walled garden Very good for the vendors

40. AG Projects NGN Signaling Forum - 2006 Differentiation in price become less and less an argument in a flate-rate services model

41. AG Projects NGN Signaling Forum - 2006 Paying for two networks PSTN and Internet is expensive, migrating to an all IP network should be cost effective

42. AG Projects NGN Signaling Forum - 2006 But you cannot keep the benefits for yourself, you must share them with your customers

43. AG Projects NGN Signaling Forum - 2006 You should not pay to migrate to IP if all you can offer is an old voice service

44. AG Projects NGN Signaling Forum - 2006 You cannot maintain your todays revenues while offering only voice and paying for migration to IP

45. AG Projects NGN Signaling Forum - 2006 Innovation is the only possible driving force for new revenues, voice should be only one of the possible services

46. AG Projects NGN Signaling Forum - 2006 And innovation happens only at the edge, so dont build a walled garden

47. AG Projects NGN Signaling Forum - 2006 Building walled gardens does not justify the costs and limit the innovation at the edge, the basic principle that boosted the Internet

48. AG Projects NGN Signaling Forum - 2006 By the time you finish building up your walled garden, the customers will be safely outside. Adrian Georgescu

49. AG Projects NGN Signaling Forum - 2006 What assets do you have compatible with the Internet?

50. AG Projects NGN Signaling Forum - 2006 Your customers, obviously!

51. AG Projects NGN Signaling Forum - 2006 What can you offer them in the NGN context?

52. AG Projects NGN Signaling Forum - 2006 Internet Access (Copper, Fibber, Wireless) Identity (SIM card) Terminals (devices and software) Presence (Integration between communication and business) Digital identity and certificate management Addressing and Numbering Connection to and from PSTN

53. AG Projects NGN Signaling Forum - 2006 Addressing and Numbering

54. AG Projects NGN Signaling Forum - 2006 Address is a sticky product

55. AG Projects NGN Signaling Forum - 2006 Sticky products means sticky customers

56. AG Projects NGN Signaling Forum - 2006 You dont want to loose your e-mail address, right?

57. AG Projects NGN Signaling Forum - 2006 Some accept to loose their telephone numbers and get new ones because of the geographic nature of numbering resources

58. AG Projects NGN Signaling Forum - 2006 NGN main addressing scheme is a SIP address User@Domain

59. AG Projects NGN Signaling Forum - 2006 You can use a number but is still a number@domain Number@Domain

60. AG Projects NGN Signaling Forum - 2006 A telephone number is just another attribute of the SIP address

61. AG Projects NGN Signaling Forum - 2006 You can have more than one telephone number mapped to a SIP address

62. AG Projects NGN Signaling Forum - 2006 My identity is ag@ag-projects.com

63. AG Projects NGN Signaling Forum - 2006 You can reach me by both email and voice using SIP to ag@ag-projects.com

64. AG Projects NGN Signaling Forum - 2006 I want to be reachable also from PSTN or IP devices with 12 keys

65. AG Projects NGN Signaling Forum - 2006 You can reach me if you dial: +31208005169 +40317105169ag@ag-projects.com

66. AG Projects NGN Signaling Forum - 2006 +31208005169 +40317105169ag@ag-projects.com henry@mci.com From PSTN or Internet From the Internet

67. AG Projects NGN Signaling Forum - 2006 +31208005169 +40317105169ag@ag-projects.com Mapping E.164 telephone numbers to IP addressing schemes is called ENUM SIP

68. AG Projects NGN Signaling Forum - 2006 ENUM is defined by the Internet Engineering Task Force (IETF) in RFC3761 as: the mapping of Telephone Numbers to Uniform Resource Identifiers (URIs) using the Domain Name System (DNS) in the domain e164.arpa

69. AG Projects NGN Signaling Forum - 2006 The purpose of ENUM is to enable the convergence between the PSTN and the Internet and enable new applications based on E164 numbers

70. AG Projects NGN Signaling Forum - 2006 ENUM has been only recently adopted by 3GPP

71. AG Projects NGN Signaling Forum - 2006 ENUM is used today by VoIP operators. Eithout it, calls between their islands will still go through PSTN

72. AG Projects NGN Signaling Forum - 2006 Without ENUM there is no way you can address a subscriber from one IMS domain to another one Because any number on IP is Number@DomainNumber@Domain The Domain part can be looked up only by an ENUM query

73. AG Projects NGN Signaling Forum - 2006 ENUM allows you to point a numbering resource to its network hosts and specify which protocol can be used to connect SIP,H323, SS7, Email, more than 15 are standardized today

74. AG Projects NGN Signaling Forum - 2006 Number portability on PSTN Current telephone number portability works with limited success and dependent on regulatory in each country VoIP Providers depend on SS7 IN database for number portability, is slow expensive and not Internet ready It takes 3 months to port my number from KPN to Vodafone Porting numbers between mobile and fixed operators is still a dream Cannot port numbers from one country to another

75. AG Projects NGN Signaling Forum - 2006 Number portability on IP By simply pointing the website name to the new IP address of the server you are done When you move your website from one hosting provider to another you get a new IP address but you do not change the name of your website On the Internet you already have portability. Without maybe being aware, everybody is using it, the DNS.

76. AG Projects NGN Signaling Forum - 2006 You dont send a fax You dont wait for 3 months You do it yourself when you want and how you want Number portability on IP There is no regulatory, agency or government office that intermediates the changes in the DNS. Internet is much more cost effective than PSTN, there are no administrative barriers that hinders the porting process

77. AG Projects NGN Signaling Forum - 2006 Number portability on IP SIP protocol: maps the phone IP:port to a SIP address ENUM protocol: maps the E.164 number to a SIP address SIP with ENUM combine the logic of uniting the identity (from both Internet and PSTN) with the access, the device and the service Voice over IP is another Internet application, so we can use the same principles that apply for web and e-mail

81. AG Projects NGN Signaling Forum - 2006 Business models based on ENUM

82. AG Projects NGN Signaling Forum - 2006 You can sell identities independent of the VoIP service

83. AG Projects NGN Signaling Forum - 2006 Connect VoIP islands (ENUM exchange) Sell DID numbers worldwide Enable video and IM for enterprises Number portability solution (can replace COIN)
