IM in the Fixed Environment
IM in the fixed environment is perhaps best exemplified by the likes of AOL, Microsoft, and
Yahoo, which each have a large base of IM users that
typically use IM on a fixed client, such as a laptop computer. Fixed IM includes a rich
User Interface (UI) experience and high bandwidth.
Characteristics of MIM
In a mobile environment, the user is constrained by bandwidth and the UI. However, the
user has the advantage of mobility. MIM users will desire to message with other MIM users
as well as fixed IM users on networks such as AOL, Microsoft and Yahoo. MIM allows users
to address messages to other users (via various bearers) using an alias (or user name) and
address book, allowing the sender to know when his/her "buddies" are available.
SMS versus MIM
SMS is a bearer that can be used for MIM. By itself, SMS does not include alias
capabilities nor does it allow for confirmation that the intended recipient is available.
Being transaction based (rather than session based), plain SMS (without MIM) does not
allow the send to have a high degree of confidence that the recipient will receive the
message in real-time. MIM allows the community of users to register as being presence
and/or available, allowing for more real-time text messaging and communications than would
be possible with traditional mobile messaging.
Future of MIM
Future MIM systems will be much more robust and pervasive, encompassing more valuable
functionality and including interoperability between IM systems.
Rich and Robust Presence
Future MIM systems will likely include rich and robust
Presence and Location Based Services capabilities,
which will enhance the system to be able to detect the presence, availability, and/or
location of fellow MIM users.
Interoperability and Inter-carrier Messaging
Future MIM systems will likely leverage network mediation to enable messaging between
MIM and fixed IM systems. This will be the key for much more wide scale adoption and
usage.
