User Profile Management for Personalized Telecom Service

Huan Wang; Xiaomin Shi; Yan Li; Heng Chang; Weiliang Chen; Jie Tang; Eduardo Martins

With the emergence of Information Communication Technology (ICT), enabling end users to take part in telecom service creation is critical for telecom operators. To stimulate the production of end user-generated services, the service platform should provide adaptation and personalization mechanisms to end users. We present a user profile repository approach that takes account of the personalization and adaptation of telecom service during creation and execution. It is shown how to interact with other components in order to enable creation, deployment and execution of services in a personalized way. We design the architecture of user profile repository, and implement a prototype to verify the functionality. We present how to use IETF XCAP (XML Configuration Access Protocol) protocol to handle user profiles data, and use SIP notification mechanism to subscribe user profiles data in the User Profile Repository.
