I found that the MS previous LAC was of 2G network. When it enters a 3G network it requests for location update.And the LU was rejected with cause “no suitable cell available”. Some 1 can please explain this? 24th July 2009 at 05:12 #58160 PanGuest Dear, RNP2! See subscription restriction in HLR. It is subscription dependent cause (any regional zone or RAT restrictions for that MS). 24th July 2009 at 15:17 #58161 RNP2Guest Thanks Pan Author Posts Viewing 3 posts - 1 through 3 (of 3 total) The forum ‘Telecom Design’ is closed to new topics and replies.
