 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)
