Concatenated (Long) SMS Segmentation Information Always Encoded as Optional "sar_*" Parameters When Using a SSMN Node (Doc ID 1984495.1)

Applies to:

Oracle Communications Network Charging and Control - Version 5.0.0 to 5.0.2 [Release 5.0]
Oracle Solaris on SPARC (64-bit)


With the release of Oracle Network Charging and Control (NCC), a feature which allows operators to modify the outgoing Originating/Destination Type of Number (TON) and outgoing Originating/Destination Numbering Type Indicator (PI) in an Advance Control Services (ACS) Control Plan.

This is achieved by setting specific Profile Tags (SSMN Originating TON Override, SSMN Destination TON Override, SSMN Originating NPI Override, SSMN Destination NPI Override) which are then used by the Send Short Message Notification (SSMN) node which can be configured to copy the incoming SMS.

More specific information on this can be found in the NCC User Documentation or please feel free to contact Oracle Support.

A problem exists with this feature in NCC when the short message being processed is a long or concatenated SMS (multipart) with a Global Systems for Mobile (GSM) User Data Header (UDH) where the outgoing Short Message Peer to Peer (SMPP) SMS now has the segmentation information encoded in the following SMPP specific fields:

This can be seen, if a network trace is taken, as follows:



Although this is a valid encoding of these fields in SMPP, it is possible for downstream network elements to not correctly interpret these fields resulting in concatenated messages arriving at the recipients handset as discrete messages and/or out of order.


Installation of NCC to utlise the ability to set the outgoing TON/NPI and concatenated SMS traffic is triggering to NCC.
