TTA NGN Testbed Construction afoot between Korea, China and Japan The Next-Generation Network (NGN) Working Group Meeting of the China/Japan/Korea (CJK) Standards Meeting was held in Beijing, China over two days June 24 and 26 to further cooperation on IT standards This CJK Standard Meeting is a conference operated jointly by the Korean Telecommunications Technology Association (TTA), China CCSA, and Japan TTC. At this fourth NGN WG meeting, concrete strategies were discussed in relation to constructing a testbed between the three countries. To briefly summarize the Meeting's main decision, after first building a testbed between Korea and China for the construction of a stable testbed, Japan since agreed to take part. The three nations agreed to decide during next meeting how this would come about and the contribution of each to the project. Moreover, the three countries agreed to base the utilization of the testbed and examine the results derived from it according to international standards. Korea plans to make the most of this arrangement to get its verified technology accepted as an international standard. The next 5th CJK NCN WG Meeting will be held in Seoul in December 2005, where concrete discussions on the proposed testbed structure plus test methods and items between the three nations will take place. Korean DMB means creation of new applications The Korean TTA announced that TTA ground wave DMB standard formulated in 2004 for domestic multimedia cellular mobile broadcast was adopted as the Europe Standard (ETSI) as of June 29, this year. The title of the adopted standard is Digital Audio Broadcasting, DMB Video Services (ETSI TS 102 428) and it can be downloaded from the ETSI homepage ( The adoption as the Europe Standard has great significance that it is the first case that a Korean broadcasting technology has succeeded in being the subject of international standardization. An official at TTA involved in terrestrial-wave DMB international standardization process said: "Since Korea technology has been accepted as a standard, this means it's going to be easier for the domestic industry to make inroads into oversea markets". The biggest reason behind the acceptance of terrestrial-wave DMB technology as an international standard lies in that Korea presented a service through which it is possible to create new applications. Being first with ground wave DMB technology means Korea has a good chance for it to be accepted by other countries looking to implement the same type of service. For instance, Bayern Broadcasting Commission of Germany began its pilot service in March 2005 based on the Korean ground wave DMB standard, which will likely lead to the commercialization of Korean DMB in Germany once the service comes to an end. Since Korean DMB will be used to broadcast the opening ceremonies and some of the games of the 2006 World Cup, it will likely make an impact on the foreign visitors who visit Germany next year. The TTA established 5 standards in relation to DMB data broadcasting. The DMB data service breaks down into PAD (Program Associated Data) and NPAD (Non-PAD). PAD can be utilized to provide a slide show accompanied by music, while NPAD offers services such as traffic information as well as a downloadable audio and video service. The TTA official said the standards that have been adopted permit full-scale DMB data broadcasting. TTA nails down second stage of 2.3GHz WiBro standard In late June 2004, the TTA enacted the first stage of the WiBro standard that supports a transmission speed of 30Mbps. As part of an effort to win international standardization, the TTA revised the first stage of the standard for harmonization with IEEE 802.16 on December 2004. Since the enactment of the first stage WiBro standard, the TTA has been pursuing the second stage standardization of 2.3GHz WiBro. By getting a standard proposal adopted at this time, it will serve to boost the commercialization of the WiBro service due to come on stream in the first half of next year. The 3GPP2 Conference under the auspices of the TTA The 3GPP2 (3rd Generation Partnership Project 2) Conference was held on June 20-30 at the Intercontinental Seoul under the auspices of the TTA. An "evolution workshop" was held June 27-28 at the conference for the purpose of discussing standards for the fourth-generation mobile communication system. The TTA official said that corresponding measures to support fourth-generation technology development such as network structure, and wireless connection norms since IMT-2000 were widely discussed. He added that representatives of institutions such as ITU, WWRF and CJK were present to announce their agendas as to how they would proceed. In addition, a total of 250 attendees including standardization experts from bodies such as Korea's TTA, TIA from the U.S., CCSA from China, plus TTC and ARIB from Japan. They also included company experts on mobile communication standards and representatives of 4 technical subcommittee conferences such as the cdma2000 technology subcommittee meeting and the wireless connection technology subcommittee meeting. ___________________________________________________________
