Hello
I want to decode the ANSI MAP Authentication Directive Invoke message in wireshark-1.0.6.
But the wireshark shows two missing parameters errors. They are as follows
1.BER Error: Missing field in SET class:CONTEXT(2) tag:77 expected
2.BER Error: Missing field in SET class:CONTEXT(2) tag:182 expected
But according to the section 2.2 of the spec.
http://www.3gpp2.org/Public_html/specs/X.S0004-540-E_v2.0_070723.pdf
here there are two mandatory parameters for the message AUTHDIR.
1. Electronic serial number
2. MSID(i.e MIN/IMSI)
That i have already given in my message.
Then why wireshark shows tag:77 and tag:182 errors?
That means it considers two extra parameters as mandatory. Plz suggest what is the problem with it?
For parameters the spec is
http://www.3gpp2.org/Public_html/specs/X.S0004-550-E_v2.0_070723.pdf
Similarly when i want to decode ANSI MAP Feature Request Invoke message, it shows 5 missing parameters errors. They are as
follows
BER Error: Missing field in SET class:CONTEXT(2) tag:1 expected
BER Error: Missing field in SET class:CONTEXT(2) tag:6 expected
BER Error: Missing field in SET class:CONTEXT(2) tag:7 expected
BER Error: Missing field in SET class:CONTEXT(2) tag:2 expected
BER Error: Missing field in SET class:CONTEXT(2) tag:134 expected
But according to the section 2.20 of the spec.
http://www.3gpp2.org/Public_html/specs/X.S0004-540-E_v2.0_070723.pdf
here there are 3 mandatory parameters for the message FeatureRequest.
1.Digits(Dialed)
2.Electronic serial number
3. MSID(i.e MIN/IMSI)
That i have already given in my message.
Then why wireshark shows the above tag errors? Plz suggest.
I have attached the traces for the above two messages.
Plz suggest what is the problem with the above two messages in wireshark-1.0.6.
