Patch Set 1: Code-Review-1

(1 comment)

https://gerrit.osmocom.org/#/c/7059/1/src/libmsc/gsm_04_08.c
File src/libmsc/gsm_04_08.c:

Line 3683: 		return GSM48_REJECT_PROTOCOL_ERROR;
remember, this is the cause value as sent back to the MS.

What has the MS done wrong in terms of a "protocol error" in the messages it has sent in order to provoke this?  I think these cases are about some problem between MSC and VLR?  If yes, this cause value is not applicable.

Section 8 of TS 24.008 unfortunately is not very precise when it comes to all possible error cases/causes. However, Annex G of the same spec explicitly states that "protocol error" relates to an invalid message (sent by the MS in this situation).

Without comprehensive review I would argue that 17 (netwokr failure) is more applicable both here and a few lines below.
