Harald Welte fdd3ccbc02 cbsp: Reject CBSP WRITE for emergency if emergency already active 
From 3GPP TS 48.018:

If only the New Serial Number IE, and not the Old Serial Number IE, is
included in the WRITE-REPLACE message,then the BSC shall interpret the
message as a write request, i.e. a broadcast request of a new emergency
message without replacing an ongoing emergency message broadcast.

Only one emergency message at the time can be broadcasted in a cell. If
a write request is received for a cell where an emergency message
broadcast is currently ongoing, the write request is considered as
failed.
