This paper introduces a mobile agent based implementation of a modified TINA access session to support personal mobility and retailer selection. The presented design allows users to access services according to their personal profiles even though they are visiting a foreign domain. The market of retailers, content and connectivity providers is envisioned to be open and competitive to the extent that the user is able to choose the service offer suiting his needs in the most optimal way in each session. The key innovations are the implementation of specialized user agents and the extension of access sessions with retailer selection sequences. Within the design, the TINA user agent is replaced by several specialized mobile agents.
