Hello Vasa
Thank you for your answer.
Now I am working on decoding of GSM MAP,so ExtensionContainer is defined in
(Digital cellular telecommunications system (Phase 2+);
Mobile Application Part (MAP) specification
(GSM 09.02 version 6.2.0 Release 1997))
Your explain I have understood, but now i don't have any particular data ( Private
data ) to encode,I mean that the data stream in fact such as:
VLR-Capability ::= SEQUENCE{
supportedCamelPhases [0] SupportedCamelPhases OPTIONAL,
extensionContainer ExtensionContainer OPTIONAL,
... }
My question is:can I ignore the extensionContainer in my decoding program?(if
so,another question about ASN.1&BER is come out: a SEQUENCE,only include one subtype,
at this time, will it ignore the tag (0x30 ) of SEQUENCE in encoding by "IMPLICIT"?)
just like this:
A ::= SEQUENCE{
B INTEGER
}
C A::={16}
the encode of C is: 02 01 10 or 30 03 02 01 10 ??
(IN GSM MAP,all types are "IMPLICIT" )
