infoX-SMS: IRDB, SMs Without Calling Number

IRDB

The SMS system supports the IRDB service. The IRDB service provides the
refreshment service of operator list for roaming TDMA MSs. An IRDB delivery tool is
installed together with the SMS system. The delivery tool loads IRDB information list
from files and then sends the messages to the TDMA MSs as the flow specified by
EIA/TIA 136-730.

Note:
This function is applied in the TDMA network only and is applied in the current
network.

Supporting UCP 4.0

Connecting with the UCPGateWay, the SMS system processes ESME messages
which support the UCP protocol in the X.25 network or TCP network. The SMPP 3.4
protocol is adopted between the UPT and SMSC, and the UCP 4.0 protocol is
adopted between the UCPGateWay and ESME. The protocol contains the following
commands:

Session management: sending connection request SMs
Multiple address call input: sending SMs in batches
Submit Short Message: submitting SMs
Delivery Short Message: sending SMs
Delivery notification: status notification SMs
Modify Short Message: replacing SMs
Inquiry message: querying SMs
Delete message: deleting SMs
MT alert: status notification SMs

SMs Without Calling Number

Some devices do not carry a calling number when submitting the submit_sm
message through the SMPP interface. The SMS system can process the SM by
adding a called number according to the configuration.

Time Zone Features

The SMS system can process information of different time zones.

  • The SMS system can deliver SMs with time zone information, which guarantees that the time information in the SMs received by roaming subscribers is correct.
  • The SMS system can process MO SMs with time zone information.
