Abstract

This article provides a mechanism to enable a user to query his/her past IM sessions. Most IM systems allow the user to save chat sessions locally. This article describes a way to aggregate IM data saved at multiple client devices to support the above queries. To enable this, the IM server keeps track of client devices (e.g. PCs, laptops, cell phones, PDAs, etc) its users have used in past. This information could be a tuple that includes userid, machine-type, machine-address, IM-session-start-time, and IM-session-end-time.

Method for Supporting Queries on Instant Messaging Sessions

IM systems now allow users to have multiple simultaneous login sessions. For example, a user could be logged in from a work machine and a lab machine at the same time. This raises interesting problems as illustrated by the example below.

Consider John Doe who goes on a lunch break while being logged on at his work machine. The IM server will continue to deliver all IMs to John Doe's work machine. During the lunch break, John Doe wants to have IM access by logging on using a cell phone/PDA. Current IM systems can deliver IMs to multiple devices. However, current IM systems do not provide any support if John Doe wants to check IMs that have already been delivered at his work machine.

The above problem occurs because of the inability of existing IM software to support queries on a user's recent history of IM chat sessions. This problem is not unique to cases where a user has multiple simultaneous login sessions. As described below, this problem occur even in other situations:
* A user wants to quickly access past IM sessions delivered to one machine from a remote machine. For example, accessing userid/password delivered to a work machine from the lab.

* A user logs in from another device to check IMs delivered to him/her on another machine.

* A user wants to review past ICT polls/broadcasts.
* An IM client window is closed by mistake.

The problem is illustrated in the figure below.
