Abstract

An apparatus and method of mapping a short message service (SMS) information from a first communications system to a corresponding message in a second, different cellular system is claimed. SMS information having a format required by the first communication system is received. The SMS information is mapped into a format required by the second communication system. Additional information is appended, if necessary, or information is removed as being extraneous information, if necessary, as required by the second communication system.

wherein the means for appending or removing further comprises means for determining a size of a destination address field in the received SMS information, and wherein the means for appending or removing is configured to append or not append based on the size of the destination address field.

10. The apparatus as set forth in claim 9, wherein said first cellular communications system is a CDMA system.

11. The apparatus as set forth in claim 10, wherein said second cellular communications system is a GSM system.

12. The apparatus as set forth in claim 10 wherein the second cellular communications system is an iDEN system.

23. The apparatus as set forth in claim 9, wherein the means for appending or removing is further configured to append if the size of the destination address is less than a predetermined length.

24. The apparatus as set forth in claim 9, wherein the means for appending or removing is further configured to determine a size of a parameter length in the received SMS information, and wherein the means for appending or removing is further configured to append if the size of the destination address is less than the size of the parameter length.
