Communication Terminal Address Information Transmission

The patent applies preliminary action by having the primary communication facility transmit secondary address information (such as email addresses) along with primary address information during the connection setup phase. This allows the secondary address information to be available in advance at the called facility, eliminating the need for complex manual or electronic determination later when data transmission is needed.

The patent uses the connection signaling process as an intermediary mechanism to transfer secondary address information from the calling facility to the called facility. This intermediary transmission during call setup simplifies subsequent data transmission by providing the necessary address information through an existing communication channel, avoiding complex direct determination processes.

The patent implements universality by enabling communication facilities to handle multiple communication services (voice, data, email) through a unified architecture. The primary communication facility can initiate both voice calls and data transmissions, and the called facility can receive and process both types of communications using the same infrastructure and address information, thus achieving multi-functionality without proportionally increasing complexity.

The patent applies preliminary action by establishing the secondary address information during the initial connection setup phase, which enables subsequent flexible use of different communication services. This preliminary transmission of address information creates a foundation that simplifies later service switching and integration, allowing the system to handle multiple services without requiring complex real-time determination processes.
