Overview

You may need to know how to implement a blacklist so some subscribers do not receive SMS messages.

Information

There are two options for implementing blacklists:

• Use a routing list associated with routing tables: This is the easiest way to implement, but it is managed via GUI, and does not support too many entries. Both ranges and complete MSISDNs can be added to these lists.
• Use AutoBlackList (ABL) or Non-Provisionable Service (NPS): NPS is a simple flag service that can be set for subscribers in the SPF DataBase. Then, it is associated with routing rules to actually block the messages. With this option, the MSISDN's can be inserted into the blacklist via SOAP commands. Only complete MSISDNs are supported. With AutoBlackList, a SOAP command can be used to block MSISDNs permanently or only for a specific time. After that, it is automatically deleted. Although this option is more flexible and supports several entries, you must be aware that:
  • The product already contains a SOAP interface, so the integration work is on the customer's side with SMSC.
  • It would require a new project for PS services so that some PS hours get allocated for designing, configuring, testing, and rolling out this functionality.
