Hi,

Thanks for your assistance.

So far from my analysis, this is what I have got:

After the BTS sends Location Update Accept message to the MS,  the MS
responds with a MM status message saying
"Invalid Mandatory Information".

In a working case, the MS should respond with a TMSI Reallocation Complete
message which is not happening.
