We should aim at implementing later releases, so the question is rather 'do we want rel 4, rel 5, rel 7' and not 'do we want rel 98 or 99'. As all the later releases >= R99 use the two upper bits as sequence numbers, the question is simple: simply use the >= R99 definition.

Nice, I like simple ;)

IIRC, there is a bit somewhere where the GPRS core network (SGSN) indicates to the MS whether it is a R98 or R99 core network. I think we have to make sure to set this bit right, and apart from that use the >= R99 definitions.

Daniel / Max, have you come across that bit yet?

Thanks!
