Abstract
A technique is provided for allocating publicly accessible IP addresses to an initiating mobile device to establish peer-to-peer session-based instant messaging with a target mobile device residing on a separate network without the need for using an instant messaging registration or log-in server to provide presence information. Session-based instant messaging communications between mobile devices are established by transmitting necessary address information through page-based messaging services that utilize the underlying digital mobile network databases and services to resolve the identification and location of the mobile devices.
