9.3. SMS: Short Message Services

 Short Message Services (SMS) is a feature-rich GSM service. The Enfora Enabler LPP G
module can perform the following tasks:
 Sending and receiving binary messages of up to 160 characters (7-bit characters)
 Sending and receiving text messages of up to 140 bytes (8-bit data)
 Submitting a SMS Protocol Data Unit (PDU) to a SMSC (Short Message Service Center) and
storing a copy of the PDU until either a report arrives from the network or a timer expires
 Receiving a SMS PDU from a SMSC
 Returning a delivery report to the network for a previously received message
 Receiving a report from the network
 Notifying the network when the module has sufficient memory capacity available to receive one or
more SMS messages (after the module had previously rejected a message because its memory
capacity was exceeded)

9.4. SIM Operation

9.4.1. Provisioning the SIM

The SIM can support optional features or services. Most operators typically configure the SIM to
send/receive voice calls and to receive SMS; however, some may require an additional tariff to
enable the SIM to send SMS. The transmission of circuit switched and GPRS data are also
additional services that may be required to allow the service:
 Mobile-originated (MO): allows making a service request (such as, making a call or sending an
SMS)
 Mobile-terminated (MT): allows receiving a service request (such as, receiving a phone call or an
SMS)
 The GSM SIM can have multiple telephone numbers.
It is imperative for the Enfora Enabler LPP G module that the SIM be configured for the optional
services that are required for the application.

9.5. GPRS Services Supported by the Enfora Enabler LPP G Module

The Enfora Enabler LPP G module supports the following GPRS (modes of operation) that must be
enabled by the operator:
 GPRS Packet Connectivity (MO and MT) with Both Dynamic and Static IP option
 GPRS SMS (MO and MT): uses the IP (Dynamic or Static) set by the operator
 Multiple APN Setting
 Quality of Service Options
