it will give a response to the SC.
<TP-UDL>: Number of bytes occupied by the “user data” domain. If the value is 0, the
“User data” domain does not exist.
<TP-UD>: The “user data” domain may include “user data header”. If it includes the
header (namely, the value of bit6 in byte0 is 1), the value of TP-UDL is equal to the
length filled in the “User-Data-Header” plus the length of “User-Data”. The value of
TP-UDL depends on the specific coding mode. If it is a 7-bit default code, it indicates
that there are a total of how many septets; if it is a 8-bit code, it indicates there are a
total of how many Octets; if it is a UCS2 code, the TP-UDL still means a total of how
many Octets; if there are compressed 7-bit or 8bit or UCS2 codes, the TP-UDL
indicates there are a total of how many Octets after compression. The specific
representation structure in the “User data” domain is shown in the following diagram:
