Context Awareness Service Value Chain

Telecommunication industry from birth to today has gone a hundred years of development. The traditional voice service can not satisfy the communication requirements of users, so all kinds of new business (value-added services) came into being. With the social and technological progress and development, as well as the improvement of people's income level and cultural quality, demand to value-added telecom services from various users is higher and higher.User'demands to telecommunications services show diverse and personalization trend. Although telecom operators have made many efforts to introduce various telecom value-added services, unfortunately, the current value-added services are not effectively meet user needs; of course, they do not bring expected profits to operators. Under this circumstance, new services are urgently needed to guide consumer demand, stimulate business volume, and promote revenue growth, among which the mobile information service is one of the main trends.Context awareness service is one kind of mobile information services. It utilizes intelligent terminals and intelligent network to peiceive user's context, and executes user data mining and predicts user behavior through intelligent computing. Ultimately it provides users with personalized and accurate information services. It is a fusion of different industries. It can effectively meet individual needs of different users and make people's lives easier. Context awareness is right the research object of this paper.There are eight chapters in this paper. Research background and research contexts are introduced in Chapter 1. Chapter 2, Chapter 3, Chapter 4, Chapter 5, Chapter 6 and Chapter 7 are all the core of the paper. A novel context awareness service dicision method based on the description of context awareness service is proposed in Chapter 2. Users' perceived value-oriented value chain model of context awareness service is described in Chapter 3. From the management perspective, some studies on context awareness service value chain are conducted in Chapter 4, Chapter 5, Chapter 6 and Chapter 7 including partner choosing, investing, profit distribution and task allocation. General summary is given in Chapter 8, the last chapter.Chapter 1 is "Introduction". It introduces the background and reason of studying on context awareness service, and establishes context awareness service as the research object of the paper. The first section introduces research background from two aspects:context awareness service and context awareness service value chain. The second section reviews the current research status of context awareness service and value chain respectively. The third section states the main contents and innovation of the paper. Basic framework and structure of the paper are described in the fourth section. Chapter 2 is "Context awareness service". This chapter covers two aspects:the first, the concept description of context awareness service is given, and an application example of context awareness service is proposed; the second, a new context awareness service decision method is put forward based on rough set theory and fuzzy theory.Chapter 3, "Context awareness service value chain". The first section does some deep analysis on the concept of value chain. The second section introduces the basic idea of modeling. Users'value in context awareness service is examined in the third section. The fourth section describes the specific process of modeling. The structure patterns are classified in the last part.Chapter 4, "Choosing of members of value chain". Firstly, an index system is established to evaluation the member enterprises of value chain. Secondly, differ weights are endowed through AHP, and then fuzzy comprehensive evaluation method is applied to conduct evaluation. Lastly, a numerical example is given to illustrate the choosing method.Chapter 5, "Investment game of the value chain". The first section establishes a game model of investment to the value chain among member enterprises. The second section discusses the game model under two conditions. The third section solves the model according to particular case. The fourth section analysis the two solutions and some meaningful conclusions are given in the last section.Chapter 6 is "Profit distribution of the value chain". This chapter mainly focuses on the value chain profit distribution problem. The first section gives the model assumption. A number of principles of income distribution are summarized in the second section. The third section describes some classical methods of profit distribution and makes a comparative analysis. The fourth section constructs a model of profit distribution based on cooperative game theory, and does some improvement to Shapley Value method, supported by a simulation example.Chapter 7 is "Task allocation of value chain". The first section briefly introduces the basic theory, and the second section establishes a specific task allocation model of context awareness service value chain, and gives practical task allocation program, supplemented by a simulation example in the third section.Chapter 8, "Summary and prospects", is a concise summary of the paper including research achievements and research deficiencies of the paper as well as some future research directions.
