Privacy Based Access to Parlay X Location Services

Next generation networks (NGN) stipulate an open access of core networks, which were previously closed. Service-oriented architecture (SOA) is a promising way to provide the access to third party providers. So, web services, as the prevalent realisation of SOA, constitute a standard middleware between service providers and cellular networks. However the spread of new innovative services run into the problem of the privacy of personal data. Indeed, service providers will hold more and more sensitive information and users are suspicious for revealing their personal data to unauthorized and unwanted parties. Henceforth, current web service standards lack of a clear solution for providing privacy policy. We suggest that the open access of operator networks to third parties goes with the respect of the privacy policy of users. In this paper, we propose to add to parlay X gateway a novel privacy Web service, which is responsible for managing and ensuring privacy of users. To validate our solution, we apply it to location services (LCS), which is a major capability provided by 2G and 3G cellular networks.
