Transport Layer Protocol Selection over Ga Interface
Benefits
This new support provides facility to configure the transport layer protocol for Ga interface
on AGW (GSNs). Now operator can run Ga interface on TCP as well.
on AGW (GSNs). Now operator can run Ga interface on TCP as well.
Description
Currently Ga interface between AGW and GTPP server was supported with UDP as default
transport layer protocol. To provide connection-oriented session on Ga interface, new
configurable feature is to select between UDP and TCP as transport layer protocol for Ga
interface. For more information refer

NSAPI Encoding in Diameter
In the earlier releases, the GGSN was encoding ASCII format of the NSAPI in decimal
format. NSAPI values of 0 to 9 were encoded in single byte, but values above 10 were
encoded as 2 bytes, which lead to faulty message in the OCS.
format. NSAPI values of 0 to 9 were encoded in single byte, but values above 10 were
encoded as 2 bytes, which lead to faulty message in the OCS.
Now the ASCII format of the NSAPI is encoded in hexadecimal format to restrict the values
to one byte.
to one byte.
For example, earlier the value of 10 was encoded as 0x30 0x31 in the byte stream. Now it is
encoded as 0x41 in byte stream representing the hexadecimal value A.
