After the global trend of telecommunication liberalization in the 90s, mobile service market in West Europe, North America, Japan and Korea are moving from a rapid-growing stage to a mature stage. With the fierce market competition, the ARPU¡]Average Revenue Per User¡^coming from the voice service of mobile communication is gradually declining, and the whole market is facing a dilemma of price wars. Meanwhile, with the development of communication technology, Mobile Data Services have been launched progressively around the world. To prevent from becoming the victims like those in the internet bubbles again, every mobile communication service operator uses the differential market strategies as counterplots. This research is based on the viewpoint of changing business game taken from the co-opetition theory that was proposed by Braudenburge and Nalebuff in 1996. This research intended to explore the current status and the trend of global mobile communication services, and the market co-opetition strategies of leading companies. Furthermore, this research compares the global status with the related domestic environment and proposes a model of market strategy in this industry for our country and some suggestions for future development to change the business game of the industry. The result of this research suggests that the pure competition between mobile service providers and Value-Net players shall no longer exist, and shall be replaced by another relationship of mutually compensate cooperation and simultaneously both competition and cooperation. If those domestic operators could follow the co-opetition model to change the element of business game properly and to shape correct market strategies, it will very possibly be positively beneficial to the development of our mobile communication industry in this country.

Owing to the fast progress of mobile communication technologies and the ubiquity of mobile networks, users can communicate with each other anytime and anywhere as long as they carry their smart and tiny mobile phones. This convenient communication service is quite popular and gradually joins in the people¡¦s life. Nevertheless, lots of attacks, such as the men-in-the-middle attacks and the replay attacks, are seriously threatening the security of the mobile networks and affecting the quality of the service simultaneously. Many security mechanisms for mobile communication have been introduced in the literature. Among these mechanisms, authentication plays a very important role in the entire mobile network system and acts as the first defense against the attackers since it can ensure the correctness of the identities of communication entities before they engage in any other communication activities. Therefore, to guarantee the quality of this advanced service, an efficient (especially, user efficient) and secure authentication scheme is urgently desired. In this thesis, we will propose a robust authentication scheme for mobile communication systems. Not only does the proposed scheme achieve mutual authentication, but also it greatly reduces the computation and communication cost of mobile users as compared with the existing authentication schemes.

Abstract Competition is the leading role for traditional concept, telecommunication industry also take competition as the thinking aspect in early days. In the time of digit convergence, competition is not only found in local but in global and technology is not belonged to single company any more. The thinking of competition has not coped with the market in the future and should take the thinking of co-opetition for the strategy development. The technology of 3rd Generation mobile communication can bring telecommunication industry new opportunities by providing customers the multiple services with higher speed such as data transmission, mobile business and multimedia A/V. This research discusses the strategy management of the industry for mobile communication in the time of digit convergence by studies of competitive strategy, value-chain of industry, co-opetition theory and analysis of industry status. After summarizing the related documents, literatures and the result of interviewing the specialists in this field, we have some conclusions listed as below: 1.To have the synergy, the technology between mobile wideband and wireless wideband must operate complementarily. 2.To adapt the uncertainty of digit convergence, the service providers of mobile communication should develop co-opetition strategy. 3.Should actively take the predomination for the technology standard of the industry. 4.The thinking of building the network for mobile communication should focus on the total solution of long-term evolution for network equipments. 5.The strategy of differential service is the essential strategy for the tendency of integrating fixed mobile convergence.

After China reform in 1979, telecommunication industry in Mainland China develops speedy, especially in mobile communication market. At present mobile telephone in Mainland China exceed 40 million. Mainland China is the third market in global mobile telephone market. The mobile communication equipment corporations that's worldwide to know, such as Motorola¡BNokia¡BEricsson etc. They have entry Mainland China to establish agencies in 1980s. Those corporations start a great quantity invest and set up sole venture or joint venture companies in 1990s. This study is to analyze mobile communication market in Mainland China and understands the mobile communication equipment corporations' business strategies. How they entry Mainland China and what is the factor influence they entry.
