Hi,
Then, there is an issue with OsmoBTS when there are
too many phones are
trying to connect to it for LUR. I described this a while ago, but we haven't
had time to look more into it yet. So far we just used various workarounds to
solve it. We're looking into writing a BS power reduction algorithm, similar to
the one used in OpenBTS - If there is a severe congestion for LU's, BS will
reduce its power until the load doesn't stabilize. Then it'll slowly increase
the
power again, until it hits the LU congestion or hits the maximum specified
power.
Sure that this is a good idea? It will throw out all users at the edge of the coverage
area, maybe cause even more load, when those show up again with their accumulated
requests like call attempts, SMS, additional LU, and in fact I have never seen that
commercial networks do something like that.
Is there not some waiting queue defined in the standards, with some timers,
commanding the location updaters to wait for some period of time? Has
been a long time when I looked into this, but I mean to remember that even
OpenBTS does it this way.
Or am I totally wrong?
