from BTS to BSC?
i suggest to use two queues:
* IMM.ASS messages which grant access
* IMM.ASS messages which reject access
the first queue should have higher priority, because giving access to
mobile stations will sooner or later resolve the rach flood.
another suggestion is to use a stack, rather than a fifo. this will
ensure that latest assigned/rejected channels are handled first. we
don't need to consider how long the mobile will wait for the
assign/reject message, so we don't need to define a specific stack size.
the latest messages will always be sent out early enough. the stack
should have a limit, so oldest messages are dropped, if new messages are
added. i still have no good solution for the maximum stack size.
