Pervasive services will meet demands and expectations from all aspects. The topic has become a favorite for research in Beyond Third Generation (B3G), Next Generation Network (NGN) and Next Generation Internet (NGI) fields. The concept of the pervasive services comes from pervasive computation and B3G. Their features include pervasiveness, mobility, transparency, QoS-guarantee, customization, adaptiveness, push, security, easiness, variety and time-to-market. 3GPP, OMA and the B3G research program of the European Union (EU) have conducted a lot of research work about the different features of pervasive services. The current hot topics in the pervasive services research include context awareness and service enabling.展开更多

It has exposed many defects and shortcomings. For examples, the mechanism of using ports to distinguish services is inflexible and dangerous with the emergence of various services; the current Internet architecture does not make use of the close relationship between network resources and services, but simultaneously maintains two processing systems for the resources and services respectively, wasting both subscribers’ time and network resources; the Internet class of services granularity is not fine enough, failing to meet personalized and diversified user demands. In order to solve these problems, this paper discusses the mechanisms and key technologies for pervasive services in the new-generation Internet. The paper focuses on the definition, classification and identifier design of personalized and diversified user services. The service identifier design fulfills the unified identifier and processing of various network services, discovers the close relationship between services and resources, and can offer personalized and diversified services according to users’ demands.展开更多
