The SMS (short message service) provides a mechanism for
transmitting short messages to and from mobile phones. The service
makes use of a short message service center (SMSC), which
acts as a store-and-forward system for short messages. The wireless
network provides for the transport of short messages between the
short message service centers (SMSC) and wireless phones.
In contrast
to previous text message services such as alphanumeric paging, the
SMS (short message service) is designed to provide guaranteed
delivery of messages to the destination. Temporary failures are identified,
and the short message is stored in the network until
the destination becomes available.
The SMS (short message service) is
characterized by out-of-band packet delivery and low-bandwidth message transfer. An
active mobile phone is able to receive or submit a
short message at any time, independent of whether or not
a voice or data call is in progress.
Initial applications
of the SMS (short message service)) focused on eliminating
alphanumeric pagers by permitting two-way general-purpose messaging and notification services,
primarily for voice mail. As technology and networks matured, a
variety of services have been introduced, including electronic mail and
fax integration, paging integration, interactive banking, and information services such
as stock quotes.
