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

AG Projects NGN Signaling Forum 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

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

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

AG Projects NGN Signaling Forum Numbering and addressing in NGN Business models around ENUM

AG Projects NGN Signaling Forum For those who don't know NGN is the Internet

AG Projects NGN Signaling Forum Even if you dont agree with it

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

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

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

AG Projects NGN Signaling Forum And you migrate to all IP, SIP based communications

AG Projects NGN Signaling Forum Using the big, bad, ugly Internet

AG Projects NGN Signaling Forum No QoS, no guarantee, no central control, no regulation, no monopoly

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

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

AG Projects NGN Signaling Forum DNS is the only centralized resource on the Internet

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

AG Projects NGN Signaling Forum Internet is different than the PSTN

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

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

AG Projects NGN Signaling Forum , 0900, prepaid, IVR all together is just one application: VOICE

AG Projects NGN Signaling Forum On the Internet voice is just another application

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

AG Projects NGN Signaling Forum Do you use SIP today?

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

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

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

AG Projects NGN Signaling Forum In Internet you have connectivity and applications

AG Projects NGN Signaling Forum Voice is just another application

AG Projects NGN Signaling Forum Next to , web and others

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

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

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

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

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

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

AG Projects NGN Signaling Forum IMS is an example of such concept

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

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

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

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

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

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

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

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

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

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

AG Projects NGN Signaling Forum What assets do you have compatible with the Internet?

AG Projects NGN Signaling Forum Your customers, obviously!

AG Projects NGN Signaling Forum What can you offer them in the NGN context?

AG Projects NGN Signaling Forum 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

AG Projects NGN Signaling Forum Addressing and Numbering

AG Projects NGN Signaling Forum Address is a sticky product

AG Projects NGN Signaling Forum Sticky products means sticky customers

AG Projects NGN Signaling Forum You dont want to loose your address, right?

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

AG Projects NGN Signaling Forum NGN main addressing scheme is a SIP address

AG Projects NGN Signaling Forum You can use a number but is still a

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

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

AG Projects NGN Signaling Forum My identity is

AG Projects NGN Signaling Forum You can reach me by both and voice using SIP to

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

AG Projects NGN Signaling Forum You can reach me if you dial:

AG Projects NGN Signaling Forum From PSTN or Internet From the Internet

AG Projects NGN Signaling Forum Mapping E.164 telephone numbers to IP addressing schemes is called ENUM SIP

AG Projects NGN Signaling Forum 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

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

AG Projects NGN Signaling Forum ENUM has been only recently adopted by 3GPP

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

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

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

AG Projects NGN Signaling Forum 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

AG Projects NGN Signaling Forum 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.

AG Projects NGN Signaling Forum 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

AG Projects NGN Signaling Forum 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

AG Projects NGN Signaling Forum

End-user experience of number portability on IP

AG Projects NGN Signaling Forum Business models based on ENUM

AG Projects NGN Signaling Forum You can sell identities independent of the VoIP service

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