To realize ubiquitous computing, data should be able to be accessed from anywhere at anytime. However, for security purpose, we need to encrypt the data so that the attackers cannot obtain any information from the server. Nevertheless, the user should be able to use keywords to search and retrieve required data. To
The aim of service discovery is to discover services based on preferences given by service consumers. Many approaches are using keyword based syntactic methods and recent approaches are using semantic Web technology to enhance service discovery.

The session initiation protocol (SIP) is widely used as the signaling protocol for various services in the ubiquitous environment of the home network. SIP is a text-based protocol with characteristics of unordered and verbose headers, variable-size message, case-insensitive keyword etc., which imposes challenges for
sending a simple keyword query to the hotspot (BlueInfo Pull). The BlueInfo hotspot requests the service from the origin server in the Internet and relays the response to the mobile device, possibly after adaptation for mobile viewing. The usability of BlueInfo Pull in comparison to a mobile phone browser is demonstrated
. Simultaneously, it generates a personal context-aware dictionary dynamically from the keywords gotten via some APIs in the Internet. Currently, the information of user's context is also provided by NGN. In this paper, we explain the overview of our proposal and prototype implementation in Japanese.
