Abstract :
Nowadays wireless Mobile positioning and IM (Instant Messaging) have been widely applied worldwide, but by far there are no public researches or applications which combine the two above together. In this paper we present a new approach of location service system which realizes location-based mobile IM chatting functions. We design and develop this system on the platform of J2ME/Servlet, first apply LL-TOA (the uplink time of arrival) of base station for positioning the mobile phone, and then employ the WTK (J2ME Wireless Toolkit) to display the interface and achieve the IM function based on the user´s location. This system provides a brand-new experience of location and communicating services, and brings a high economic and market prospect.
