Here is a comprehensive and highly practical guide to SMS and MMS interworking in GSM, TDMA, and CDMA mobile communications systems. This cutting-edge book gives you the knowledge needed to plan SMS or MMS interworking both commercially and technically. You learn how to implement SMS or MMS services with interworking, pre-paid SMS or MMS services, and mobile location services. Moreover, this unique reference helps you develop software for SMS and MMS centers.

The book offers you various solutions to number portability and provides methods for barring the inbound SMS to prevent spamming. Including numerous solved examples, this authoritative reference helps you gain an in-depth understanding of the key concepts presented. From standard procedures for SMS in GSM and IS-41 networks, to algorithms for the creation and maintenance of numbering plans, this book is your single resource for all the SMS and MMS details you need for your work in the field.
