Tripathy,
Same rule..
9F8118 : 1001 1111 1000 0001 0001 1000
First 2 bit : tag class (UNIVERSAL / APPLICATION / CONTEXT-SPECIFIC /
PRIVATE)
next 1 bit : primitive/constructed
if 1 byte tag(tag value is less than 31, i.e., max 30) : next 5 bit is
value.
(For instance, the tag for MIN, 0x88(1000 1000) tag value is 8)
if 2 bye tag(tag value range 31 ~ 127) : next 5 bits filled with all 1.
next 7bits of 1 byte(except first 1 bit) is value.
(For instance, the tag for SMS_NotificationIndicator, 0x9F6D
SMS_NotificationIndicator ::= [109] OCTET STRING,
See X.218, X.209 and X.600 series for more detail.
