Hi,
I think the first part of the patch is incorrect:
3GPP TS 24.080 version 7.2.0 Release 7:
For messages transmitted via CS domain the following applies:
- When the radio connection started with a core network node of earlier than
R99, bit 8 shall be set to 0 and bit 7 is
reserved for the send sequence number in messages sent from the mobile station.
In messages sent from the
network, bits 7 and 8 are coded with a "0". See 3GPP TS 24.007 [4].
- When the radio connection started with a core network node of R'99 or later,
bits 7 and 8 are reserved for the
send sequence number in messages sent from the mobile station. In messages sent
from the network, bits 7 and 8
are coded with a "0". See 3GPP TS 24.007 [4].
For messages transmitted via PS domain the following applies:
- No sequence number shall be used. Bits 7 and 8 shall be coded with a "0". See
3GPP TS 24.007 [4]. If a
sequence number is received on the network side it shall be ignored.
I'll try to check in the last part of the patch tonight together with updated
comments.
Regards
Anders
