MO-Based GSM SMS NP

The MO-Based GSM SMS NP feature provides network information to the Short Message Service Center (SMSC) for subscribers using the GSM network. This information allows the SMSC to select a protocol to deliver SMS messages to the called party.

The MO-Based GSM SMS NP feature:

  • Intercepts SMS messages after they have undergone Prepaid Short Message Service Intercept (PPSMS) and Portability Check for Mobile Originated SMS (MNP SMS) processing and before they reach the SMSC

    Note:

    The MO-Based GSM SMS NP feature does not require the PPSMS or MNP SMS features to be enabled.
  • Decodes the TCAP/MAP message destination address and performs lookup in the number portability (NP) database
  • Modifies the destination address in the TCAP message with directory number (DN) porting information
  • Relays the message to the SMSC

The SMSC uses the DN porting information to determine whether to forward the message to other operators or to process the message for an in-network subscriber.

The MO-Based GSM SMS NP feature applies to ForwardSM SMS MSUs with ITU TCAP/MAP for either ITU or ANSI MTP messages.
