LAC 0 / paging to all BTS - OpenBSC

Hi Zecke,

I've been reviewing some of your patches:

     [paging] Use one of the two reserved LAC to page every BTS

     For the on-waves.com MSC case we want to page every BTS reached
     of the network. Our gsm_subscriber entry does not have a LAC
     entry set and defaults to zero. Use the reserved 0x0000 to
     indicate that we want to use every bts in the network.

     This will influence the paging code to start and stop paging. 
The problem is that in the current code, we use LAC == 0 to indicate that the
subscriber has sent an IMSI DETACH message, i.e. switched his phone off.

You are now redefiniing the LAC 0 to something like the opposite case, which
I don't particularly like.  Is there some alternative solution?

Regards,
