探討「次世代網路」之發展與監理

Probe into development and regulation of ''Next Generation Networks''

自從通訊業者引進次世代網路（NGNs）後，此一新技術的網路接取架構與傳統電信有很大差異，因此，監管者著手研究並想透過修改法規加以適應。對此，經過分析國內外監管制度規章後，約可濃縮成三個主要軌跡，分別是；解除管制的競爭市場、網路接取之管理及網路產權分離等三項。就第一項而言，我們要分析的是，由於NGN接取技術持續進步，是否會因此擴張其市場力量。再就第二項而言，本文就一些特定國家之實例，分別驗證其技術、市場和監管者態度等型態。經過研究後發現，首先，在接取網路上，其市場力量有增強之趨勢。其次，在網路基礎設施佈建上，是否鼓勵網路擴建或是維持業務競爭，兩者之間產生了相互抵換（trade-off）之窘境，至今仍懸而未決。第三項，我國亦可參考。最後，如將國外NGN監管的例子印證於國內，發現我國較偏向美國制度但卻缺乏市場競爭配套機制，有必要未雨綢繆加以補強。

As Next Generation Networks（NGNs）which are much different from traditional telecommunications in access network architectures have been introduced by many communication operators, regulators worldwide have embarked on reviewing and amending relevant laws in order to adapt to such developments. By analyzing both domestic and foreign regulatory systems, we can identify three key courses: deregulation and competition, management of access networks, and separation of network ownership. With regard to the first issue, we focus on the analysis whether the market power of NGN has been strengthened along with the progress of related access technologies. As for the second issue, this article identifies the developments of technologies, markets and regulators' stands in some specific countries. The key finding is that NGN's market power has been increased, especially in access networks. Lastly, with respect to the construction of network infrastructure, it remains to be an unsolved issue whether regulators should encourage network expansion or service competition. Third issue, our country can also consult. In comparison with other countries, Taiwan's regulations over NGN are similar to the US's, but lack relevant measures to safeguard market competition. Hence, there is a must to take precautions to improve the situation.
