A number of portable devices have been created that allow users to send and receive email over a wireless network while the user is on the go. These portable devices include Short Message Service (SMS)-enabled devices, two-way pagers, cellular phones with email service, and portable networked laptops or Personal Data Assistants (PDA) that use email.

  Method and System of an Email User Interface to Web Services and Web Applications with Session State

   Disclosed is a program that combines the Hypertext Markup Language (HTML) model with email technology by routing incoming emails to a web application server, parsing and processing the email messages, and sending formatted email responses back to the user. See figure for an example of one possible implementation of this infrastructure.

A persistent server-side session is maintained for each email thread, so that state information can be kept on the server between emails. A reference identification number (ID) is sent in the email subject along with a text message and a set of choices. The user receives this email on a portable device and sends a reply message containing a user selection. The subject field of the response email will retain the reference ID, which allows the server-side email processor program to load state information from the server-side session. The email is processed in accordance with the user selection.

The user starts a new session by sending a generic email to the server. Since the email is missing a valid reference ID, the server creates a new session and sends a menu of starting options back to the user. The subject field of the "main menu" email will contain a reference ID.

When an email is sent by the email processor, the email session information is stored in a hashtable, database, or other type of storage. The information can be retrieved using the reference ID as a lookup key. The session information consists of one or more name / value pairs. These pairs identify what options are to be executed when reply email is received.
