Short Message Service
The Short Message Service (SMS) is a basic service allowing the exchange of short text messages between subscribers. The first short text message is believed to have been transferred in 1992 over signaling channels of a European GSM network.
Service Description
Developed as part of the GSM Phase 1 ETSI technical specifications, the Short Message Service (SMS) allows mobile stations and other network-connected devices to exchange short text messages.
SMS Use Cases
SMS was intended to be a means of exchanging limited amounts of information between two mobile subscribers. This limited capability has become a building block for the development of more compelling services ranging from the download of ringtones to professional applications such as remote monitoring or fleet tracking.
Consumer Applications Based on SMS
Person-to-Person Messaging: This is the original use case for which SMS has been designed. This use case relates to the exchange of a short text message between two mobile subscribers. With SMS, the two most well known predictive text input algorithms are T9 from Tegic and ZI from ZI corporation.
Information Services: This is probably one of the most common use cases in the machine-to-person scenario. With information services, weather updates and financial reports can be prepared by value-added service providers and pushed to mobile handsets with SMS.
Voice Message and Fax Notifications: This use case is widely supported in GSM mobile networks. This use case relates to the reception of messages containing notifications for voice messages and fax waiting in a remote message inbox.
Internet Email Alerts: With Email alerts via SMS, subscribers are notified that one or more Email messages are waiting to be retrieved. Such an alert usually contains the address of the message originator along with the message subject and the first few words from the Email message body.
Download Services: It has become popular for mobile subscribers to customize their mobile handset. This can be done by associating ringtones to persons in the phone contact directory.
Chat Applications: During a chat session, several users can exchange messages in an interactive fashion. All messages exchanged during a session are kept in chronological order in a chat history. In the chat history, messages sent from a recipient are differentiated from messages sent from other users. Several existing mobile chat applications are based on SMS for the transport of messages.
Smart Messaging: Smart Messaging is a proprietary service developed by Nokia. This service enables the exchange of various objects via SMS. This includes the transfer of Internet configuration
parameters, business cards for PIM updates, etc.
Corporate Applications Based on SMS
Vehicle Positioning: The Global Positioning System (GPS) is a technology for determining global positions on Earth. A GPS receiver coupled to a handset, built-in or as an accessory, can provide the location of a person or equipment. This location information can be formatted in a short message and sent to a remote server via SMS. The server interprets locations received from several handsets and displays them on associated geographical maps.
Remote Monitoring: Messages can transport information about the state of remote devices. For instance, system administrators can be notified by a short message that a server is running low of resources or that a fault has been detected on a remote computer.
Operator Applications Based on SMS
Operators have used SMS as a building block for enabling the realization of several services including the ones listed below.
SIM Lock: Operators sometimes require handsets to be locked and usable with only one specific SIM. After a minimal subscription period, the user may request the operator to deactivate the lock in order to be able to use the mobile handset with another SIM (from the same operator or from another operator). If the operator agrees on the lock being deactivated, then the operator sends a short message containing a code allowing the device to be unlocked.
SIM Updates: With SMS, operators can remotely update parameters stored in the SIM. This is performed by sending one or more messages with new parameters to a mobile device. In the past, operators have used this method for updating voice mail access numbers, customer service profiles (determining which network services are accessible to the subscriber), operator name for display in idle mode on the device screen, and address book entries.
Message Waiting Indicator: Operators have used SMS as a simple way to update message waiting indicators on the receiving handset. With this mechanism, a short message contains the type of indicator (voice mail, etc.) to be updated along with the number of waiting messages.
WAP Push: The SMS can be used as a bearer for realizing theWAP push. With this configuration, a WSP protocol data unit or the URI of the content to be retrieved is encoded in a short message and sent to the receiving device. Upon reception of such a message, the WAP microbrowser intercepts the message, interprets the pushed content, and presents the content to the subscriber.
