ies can apply and gain the license from regulatory agencies. Basic service operation is under strict control of the government. For any basic service operator, the state-owned equity interest or shares shall not con- stitute less than 51%. Mobile voice and infrastructure services are largely classified as basic services. The number of MNOs in the market is determined by the government through licensing system. As the representative of the most important stakeholder, the government can interfere directly into the companies' operations, when it is necessary. Consequently, the competition in basic service market is controlled by the gov- ernment. All the basic operators are mainly state-owned companies. The two MNOs-China Mobile and China Unicom-were started in the 1990s during the telecom reform. China Mobile was in the absolute leading position with 69.4% market share at the end of 2007 [10]. The two strong nationwide MNOs left no room for MVNOs to survive in the market. In May 2008, the Chinese government started a new round reconstruction of the telecom industry for granting 3G licenses. It is expected that three MNOs will still be functioning after the recon- struction. In contrast, more effective competition system would have been estab- lished in VAS field. By the end of 2007, over 22,000 VAS licenses were granted by the regulatory agencies in China [10]. To access customers and necessary infra- structure, these VAS companies must cooperate with basic operators and provide various information services through the networks. 13.4.1.3 South Korea The policy of South Korea government has gradually changed for selecting opera- tor. When South Korea government announced the first bid for selecting national operators in 1992, they also set the rules themselves. However, later in 2000 and in 2001, South Korea government implemented a transparent bid procedure. VAS are open for competition and market. M&A between operator and CP including even broadcasting station is legally possible. Service Delivery Platforms Basica
