Mobile Number Portability: lessons from Hong Kong, China

There's a piece Court Hears Fight Over Numbers Used for Cellphones in today's New York Times about the battle to introduce mobile number portability in the United States. There are perhaps some lessons to draw from Asia, particularly Hong Kong, China. In this "mobile-mad" economy, over 90% of the population has a mobile and it probably has the most highly competitive mobile market in the world with 6 providers for slightly less than 7 million people. A few years ago (March 1999), I happened to be in Hong Kong the day the regulator, OFTA, introduced mobile number portability (MNP). You could barely walk around with huge lines to switch mobile providers flowing out of the shops and stalls (today they also hawk broadband from street stalls but that's another story...). A key reason that no mobile provider has yet been able to dominate the market is due to the high subscriber churn facilitated by MNP. Before implementing MNP, OFTA commissioned a feasibility study and a cost benefit analysis. This study concluded "A wide range of consumers will benefit from the MNP in Hong Kong. Mobile subscribers will be able to switch operators and avoid the costs and inconvenience associated with a number change. Competition in the industry will be heightened as a barrier to switching is removed, further benefiting residential and business users.

ITU Overview and ENUM Presentation

Here's the presentation (PowerPoint, PDF) I made last week to the GAC at the Rio de Janiero ICANN meeting. It gives an overview of the ITU, changes in the telecom sector, its impact on the ITU, and ITU's activities related to IP-based networks and the Internet. I also made a presentation on ITU's perspectives on ENUM (Powerpoint, PDF) in an open ICANN session.

DNS Root server operators presentation

The DNS root server operators have published the presentation (PDF) they recently made to the GAC at the Rio de Janiero ICANN meeting. The presentation (along with the recent CRADA report on root server architecture changes) emphasizes that since November 2002, zone transfers to the set of 13 root servers are not done from a.root-servers.net but rather a hidden master server. As they put it: The "A" server is not special.

Impact of Worm on Root Name Service Argues for Anycasting

Daniel Karrenberg on the inpact of the SQL worm on DNS root name service: "A further tentative conclusion is that this data (again) supports the case for distributing root service across the Internet using IP anycasting." For more explanation of anycasting, see here More anycasting of the F root server, Anycasting the root name servers and Distributing the K-Root Service by Anycast Routing [via icann.blog.us].

More anycasting of the F root server

The Internet Software Consortium has announced they've come to agreement with the Spain Internet Exchange (EspaNix) to anycast the F root server in Madrid.  For more info on anycasting on this site, see Anycasting the root name servers and Distributing the K-Root Service by Anycast Routing. This follows on from their announcement in November 2002 to create F server mirrors in the Asia-Pacific region. Update: APNIC today (January 23, 2003) made a Call for Expressions of Interest for the support of APNIC Points Of Presence in the Asia Pacific region, including potentialhosting of instances of the F root server. APNIC has also provided a root server trial FAQ.
