• Greetings from HATS
• A message from Ministry of Internal Affairs

  NGN interoperability event by HATS (Harmonization of Advanced Telecommunication Systems), supported by ITU-T, was held on 11-12th July, 2012 in Japan. Interoperability between each NGN end-terminal product was put into effect to promote new NGN for Asian operators.

1. Category of equipment: VoIP, Video Conference, HDTV Conference, IP-FAX/Multi-Function Printer, and Data transfer services.
2. Reference Point : UNI (UNI2 of NGN service by NTT)
3. Reference Documents : Q.3900 series (Q.3900-Q.3906.1, Q.3931.1-Q.3931.4, Q.3945), Q.3948 (VoIP), Q.3949 (Video Conference) and HATS test scenarios.
4. Test contents : End-to-End Multimedia service interoperability testing.
5. Date : 11-13 July 2012
6. Location : CIAJ (Tokyo, Japan)
   3rd Fl., JEI Hamamatsucho Bldg., 2-2-12 Hamamatsucho, Minato-ku, Tokyo 105-0013

7. NGN Test Environment
   For the NGN tests, multiple environments were prepared so that connection tests could be performed in different environments. Tests were conducted in the following two connection configurations:
   1. External interconnection tests between NGN terminals via a NGN test environment (reference point UNI2)　[Terminal A --- Terminal B-2]
   2. Internal interconnection tests between NGN terminals via a HGW[Terminal A --- Terminal B-1]

9. Result
   IP phones, Content Transfer and IP-Fax have a 100% success rate for both internal and external connections.
   This high success rate is a result of feedback provided from last year's test results.
   Video phones achieved the following success rates:
   external connections 44%, internal connections 75%.
   The lower success rates of Video phones compared with other equipment was due to implementation differences between WiFi smart phones; between soft phones equipped with both SD and HD codecs; the methods used for video codec negotiation and video-to-audio fallback. The reasons for the low rates are still under study and will be reflected in future standards and test procedures.
