INTRODUCTION

General Description

The Short Message Service (SMS) allows the exchange of shortmessages between a mobile station and the wireless system, andbetween the wireless system and an external device capable oftransmitting and optionally receiving short messages. The externaldevice may be a voice telephone, a data terminal or a short messageentry system.

The Short Message Service consists of message entry features,administration features, and message transmission capabilities.These features are distributed between a wireless system and theSMS message center (MC) that together make up the SMS system. Themessage center may be either separate from or physically integratedinto the wireless system.

Short message entry features are provided through interfaces tothe message center and the mobile station. Senders use theseinterfaces to enter short messages, intended destination addresses,and various delivery options.

Message center interfaces may include features such as audioresponse prompts and DTMF reception for dial-in access from voicetelephones, as well as appropriate menus and message entryprotocols for dial-in or dedicated data terminal access. Mobilestation interfaces may include keyboard and display features tosupport message entry. Additionally, a wireless voice servicesubscriber can use normal voice or data features of the mobilestation to call an SMS system to enter a message.

An SMS Teleservice can provide the option of specifying prioritylevel, future delivery time, message expiration interval, or one ormore of a series of short, pre-defined messages.

If supported by the Teleservice, the sender can requestacknowledgment that the message was received by the mobile station.An SMS recipient, after receiving a short message, can manuallyacknowledge the message. Optionally, the recipient can specify oneof a number of pre-defined messages to be returned with theacknowledgment to the sender.

SMS administration features include message storage, profileediting, verification of receipt, and status inquiry capabilities.SMS administration is not within the scope of this standard.

The SMS transmission capabilities provide for the transmissionof short messages to or from an intended mobile station, and thereturn of acknowledgments and error messages. These messages andacknowledgments are transmitted to or from the mobile stationwhether it is idle or engaged in a voice or data call.

The wireless service provider may offer SMS transmission to itswireless voice and data customers only, or may provide an SMS-onlyservice without additional voice or data transmissioncapabilities.

This standard also provides for the broadcast of messages. Allavailable mobile stations on a Paging Channel or Primary BroadcastControl Channel can receive a broadcast message. A broadcastmessage is not acknowledged by the mobile station. BroadcastMessaging Services may be made available to mobile stations on aPaging Channel or Primary Broadcast Control Channel as well asmobile stations in a call on a Traffic Channel.
