h2. Problem Areas
* Routing Lookups for network elements
** Determine HLR IP/hostname by IMSI (to know which HLR to ask during GSUP SendAuthInfo + UpdateLocation)
*** could be static table / config file with ISMI prefix, like 334-42-001-0123456 where "001" is site/network name and "0123456" is the subscriber in that site/network
*** could use something like enum/DNS
** Determine HLR IP/hostname by MSISDN (to know which HLR to ask for current serving VLR/MSC IP/hostname)
*** could be static table / config file with ISMI prefix, like 52-123-012-3456 where "012" is a prefix for the given site/network and "3456" is the subscriber in that site/network. Probably too restrictive.
*** could use something like enum/DNS
* Routing Lookups for subscribers
** determine serving VLR/MSC IP/hostname by MSISDN: [[SendRoutingInfo]]
* Synchronization
** single-master multi-slave
*** subscriber data (MSISDN, IMSI, GPRS/SMS/Voice permission, Auth keys, ...)
** distributed
*** present location of subscriber (serving VLR/MSC)
h2. Unsorted
* [[NetworkLayout]]
* [[MulticastProposal]]
