An online database of mobile country codes (MCCs) and mobile network codes (MNCs), defined by Recommendation ITU-T E.212: The international identification plan for public networks and subscriptions, is the latest addition to ITU-T’s International Numbering Resources (INR database).
MCCs are used to identify mobile telephony installations in wireless telephone networks and are used in combination with MNCs to uniquely identify network operators. The new database also provides listings of shared international mobile telephony codes, and MCC+MNC configurations used extra-territorially (MCC+MNC assigned to an operator in one country, but used in another through the establishment of a foreign base station by that operator).
Slaheddine Maaref, Tunisie Telecom: “In the past, authoritative MCC+MNC information was available only through ITU-T’s Operational Bulletin. The online database is thus a welcome addition to ITU-T’s services; offering me information of a quality and accuracy comparable to that of the Bulletin, but with the added benefits of real-time updates to its content and an ability to select and export only the information I am looking for.”
Access to the database is a membership benefit available only to ITU Member States and ITU-T Sector Members.
The database is navigable through such search criteria as codes, countries/regions or network operators. Search results can be exported to MS Word or Excel files, and can be bookmarked as favourites in one’s Internet browser.

Geneva, 14 July, 2011 - ITU is pleased to announce that the world’s newest nation, the Republic of South Sudan, has today been assigned the international dialling code 211, following the country’s formal recognition as a UN Member State.

The fledgling South Sudan Ministry of Telecommunications and Postal Services welcomed the new code, which has particular resonance for South Sudan’s citizens as representing the year in which South Sudan gained independence (2011), the date of its referendum (which took place in the first day of the first month of 2011), and a symbol of good fortune. The number had been specifically requested following a special Council of Ministers Resolution.

Reinhard Scholl, Deputy to the Director of ITU’s Telecommunication Standardization Bureau has taken a seat on the Internet Corporation for Assigned Names and Numbers (ICANN) board.

Annually, in rotation, ETSI, ITU-T and W3C appoint one non-voting liaison (TLG, Technical Liaison Group) to the ICANN Board. ICANN is responsible for the global coordination of the Internet's system of unique identifiers. These include domain names (like .org, .museum and country codes like .UK), as well as the addresses used in a variety of Internet protocols.

At ICANN’s 30th International Public Meeting in Los Angeles, Internet pioneer Vint Cerf's term as Chairman of ICANN’s Board came to an end. He was succeeded by Peter Dengate Thrush, a New Zealand lawyer and former President of InternetNZ.

The news follows a recent announcement on collaboration towards standards for the multilingual Internet made during the Internet Governance Forum.

A standardized way to identify next-of-kin (or other emergency contact) in a mobile handsets’ directory, for use in case of emergency, has been sent for next level approval by Study Group 2 in May 2008.

Currently emergency service workers searching for contact information for the next-of-kin to an injured person have no commonly understood way of identifying that person’s details. Increasingly the directory of the injured person’s mobile handset is used, since it usually contains the names and numbers of next-of-kin. However, there is no standard way to distinguish these contacts from all other entries in the mobile handset directory.

A prefix to those contacts to be dialed in case of emergency is one solution. International standards must be useable by anyone, regardless of language or script. This requirement has been met by using Arabic numerals (the digits 0 through 9) since they are known by all users around the world.

The owner of a mobile handset can indicate contacts to be dialled in case of emergency by formatting the name in the form “0nx”, where “n” is a digit from 1 through 9 and “x” is any meaningful descriptive character string (e.g. “Anna” or “spouse” or “安娜”). In the interface it would be displayed as “01Anna” or “01spouse” or “01安娜”. This descriptive string is used for the “contact name” in the mobile handset directory; the actual number of the person to call in case of emergency is used for the corresponding “contact number”.

Once this standard is approved and widely implemented by individual mobile users around the world, any emergency service worker can look at the mobile handset directory and quickly identify entries tagged by the user as contact persons to call in case of emergencies.

“Emergency contact number notation” stands on the runway to take off as a new clause in ITU-T Recommendation E.123, which currently specifies, among other things, the familiar +41 22 123 456 notation for telephone numbers and other information commonly displayed on business cards.

Following up on advice from ITU-T Study Group 2 (see previous story), the Director of TSB has assigned E.164 country code 888 to the United Nations Office for the Coordination of Humanitarian Affairs (OCHA) for the purpose of facilitating the provision of an international system of naming and addressing for terminals involved in disaster relief activities in an area of a country that has been cut off from the national telecommunications system of that country.

This separate, alternate naming and addressing system will continue in operation until such time as normal telecommunications can be restored and the disaster location is once more part of the national telecommunications infrastructure. The use of any numbering resource will therefore be relatively short lived and the resource may be re-used at a later date for another location.

Subsequent digits of the codes (for example, identification codes under the E.164 code) will be allocated and administered by OCHA.

The numbering resources are assigned solely for the use of UN emergency responders and not for other purposes. The commercial aspects of the use of the numbering resource will be negotiated between OCHA and the appropriate operators and service providers. In addition, the Mobile Network Code (MNC) 88 under the E.212 shared Mobile Country Code 901 has been assigned to OCHA for the same purposes.

Study Group 2 has recommended the allocation of the international dialing code 888 to the UN for use in disaster relief situations.

It means that in cases where the telecoms infrastructure is down, UN teams can quickly get a communications system up and running for use in coordination. The recommendation was made following a request from the United Nations Office for the Coordination of Humanitarian Affairs (OCHA). The Director of ITU's Telecommunication Standardization Bureau (TSB) will study the recommendation from Study Group 2 to allocate the code.

Study Group 2’s February meeting saw work continue on harmonizing numbering resources for child helplines.

SG 2 is looking at the issue following a request from Child Helpline International (CHI). CHI is a global network of telephone helplines and outreach services for children and young people.

Specifically SG 2 is looking at the logistics of providing a global number. It previously conducted a survey which discovered that a wide range of numbers are in use globally and that there is support in many countries for studying a more harmonized solution.

A review process will be an initial assessment of all of the various options for introducing childrens’ helplines. The fundamental question is whether a single number can be deployed worldwide. Other issues include how regulators will handle migration from existing services and who pays for the services.

At an early December meeting of ITU-T's Study Group 2 agreement on the allocation of a high-revenue international short message service (SMS) number to two international organisations for the purpose of fundraising was made. An official announcement in ITU-T's Operational Bulletin will be made following the decision of the Director of the Telecommunication Standardization Bureau.

The number +979 0767 was granted following a request from the United Nations International Children Emergency Fund (UNICEF) and the International Federation of the Red Cross and Red Crescent Societies (IFRC). It will allow the two organizations to launch relief campaigns across national boundaries, and will encourage regular donations by introducing a recognisable and non-changing number. The 767 portion of the number spells out SOS.

Texting emerged as a popular way to contribute to relief efforts during fundraising for the earthquake in Bam, Iran, 2003 and the 2004 Asian tsunami.

Until 1998, the ITU Global directory contained information both about ROAs that were Sector Members and non-Sector Members, but it now only contains information relating to ROAs that are Sector Members.

The consequence of there not being a published list of all ROAs (including those that are non-Sector Members) might limit the assistance such information can have on, for example, the bilateral exchange of information related to numbering changes or on introducing new international numbering resources.

The status of ROA is used within certain ITU-T Recommendations, e.g. E.118, E.164.1, E.169.1, E.169.2, E.212, Q.708, X.121 as a criterion regarding assignment of international numbering resources. Such a list would assist in the administration of international numbering resources and would facilitate the exchange of information between ROAs, for example, on numbering changes.

A consolidated list of Recognized Operating Agencies (ROAs) has been set up, derived from the responses received to TSB Circular 24 of 8 April 2005 and an individual communication was published in the ITU Operational Bulletin under the heading "Changes in Administrations/ROAs and other entities or Organizations".

In that Resolution, the sovereign right of each country to regulate its telecommunications, as expressed in the basic instruments of ITU, was reaffirmed. In this regard, each country has the right to authorize, prohibit or regulate call-back practices. National regulatory measures must be respected by other countries within the limits of their own legislation, and the recognized operating agencies (ROAs) and administrations concerned must communicate and collaborate.

To facilitate this collaboration, a draft guideline has been prepared under which ITU is to collect information once a year on the positions adopted by each country in respect of call-back practices within its territory and disseminate the findings by the most effective method. Administrations and ROAs receiving this information must take all necessary steps to prevent call-back practices from being supplied to countries which prohibit them. The TSB has circulated the questionnaire each year since 1996. The results were disseminated by a TSB Circular.
