Realization of personal mobility services in various situations

When an open and global telecommunication environment is realized on the distributed processing environment, there will be, actually, various situations for end users to utilize services. For instance, an end user may have to make access to services from a legacy system which does not support such a new environment, or from a domain that is closed with respect to its security policy. However, from the point of view of flexibility and scalability of service provisions, and from the business standpoints, realizations of personal mobility service in such situations are very important subjects. In this paper, we apply TINA to a promising networking architecture, and describe the realization and prototype implementation of personal mobility service
