Technology, the Internet and the Demand for NANP Numbers J. Scott Marcus Senior Advisor for Internet Technology Office of Strategic Planning and Policy Analysis, FCC The opinions expressed are my own, and do not necessarily reflect the views of the FCC or any of its commissioners.
Technology, the Internet and the Demand for NANP Numbers • Factors that might decrease demand for numbers • Factors that might increase demand for numbers • The transition to the brave new world
Factors That Might Decrease Demand • Huge interest in Voice over IP (VoIP) • Conventional phone numbers? • Use of SIP addresses? • What is a phone call? • VoIP -> Everything over IP • Telephone -> intelligent device • Decreasing relevance of geography to numbers. • Short messages (SMS)
Factors That Might Increase Demand • A multiplicity of services. • Wired, wireless, Internet, … • Substitution of calls, but not of services. • ENUM – a mapping from telephone numbers to electronic services • Associates a subscriber’s phone number with a ranked list of Internet-based services that can be used to reach him/her. • ENUM requires no changes to the North American Numbering Plan, nor to international E.164 numbering.
How Does ENUM Work? • The design of ENUM is based on the Internet’s Domain Name System (DNS). www.fcc.gov www.amazon.com www.harvard.edu • Instead of .com or .gov, ENUM uses .e164.arpa • The DNS works from right (most significant) to left (least significant), unlike phone numbers. • Consequently, ENUM entries look like this: 1.1.6.0.8.1.4.2.0.2.1.e164.arpa to represent (202) 418-0611
ENUM and Numbering • ENUM uses existing NANP numbers. It does not necessarily imply any change at all to the rate of number exhaustion. • The mapping from phone numbers to individuals is not one-to-one in either direction. • Wireline – call a PLACE • Wireless – call an INDIVIDUAL • Will people simply use phone numbers that they already have? • Will people demand new individual numbers?
In the Long Run • Will phone numbers become less important over time? • Or will they simply take on a somewhat different meaning?
The transition to the brave new world • In what time frame do the factors that might decrease the emphasis on numbers operate? • In what time frame do the factors that might increase the emphasis on numbers operate? • What are the impacts on numbering as we migrate from the old world to the new?
