The R520 is capable of sending and receiving SMS messages and linked messages.

¥ With the Short Message Service, a user can send text messages containing up to 160 charac-

ters to and from GSM mobile stations

¥ With the linked SMS, the user can link several SMS messages together to create a longer

A Service Centre (SC) acts as a a storage and forwarding centre. The R520 also supports using

SMS as a bearer type for connecting to WAP.

SMS consists of two basic services:

¥ Mobile Originated SMS (from a mobile station to an SMS-C)

¥ Mobile Terminated SMS (from an SMS-C to a mobile station)

For Mobile Originated SMS, an SMS message is sent from a Mobile Station to the SMS-C

where it is forwarded to its destination. This can be another Mobile Station, or a terminal in the

Þxed network.

A Mobile Terminated SMS is when an SMS message is forwarded from the SMS-C to a Mobile

Station. When the Mobile Station receives the message, it returns a delivery report saying the

transfer was successful.
