Oracle Communications Convergent Charging Controller - Version 6.0.1 and later
Information in this document applies to any platform.


On Oracle Communication Convergent Charging Controller (OC3C) Applications, 6.0.1 version, it is observed that Messaging Manager (MM) truncates the last character of inbound SMPP when GSM 7-bit is used. 

Consider the below sample xmsTrigger.log which shows that the MM missing the last character of the Short Message Service (SMS) when Global Systems for Mobile communications (GSM) 7-bit is used:

2018/03/08 23:53:59 69 [27798] genericSM virtual voidxms::SMSRequest::setUserDataAndUserDataHeader(const unsigned char*, size_t,xms::AvailableAlphabets, bool, bool)
2018/03/08 23:53:59 599 [27798] genericSM virtual voidxms::MessageRequest::setUserDataAndUserDataHeader(const unsigned char*,uint_t, xms::AvailableAlphabets, bool, bool)
2018/03/08 23:53:59 605 [27798] genericSM 9 characters in alphabet GSM7Bit equates to 8 octets
2018/03/08 23:53:59 683 [27798] genericSM Storing userData as alphabetGSM7Bit length is: 8

As per the Short Message Peer to Peer (SMPP) specifications, the message length value is the number of octets for the user data.

MM internally stores the characters in UTF8 (8-bit character set) and it loses the last character.
