h1. Wiki 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 {{child_pages}} * [[NetworkLayout]] * [[MulticastProposal]] * [[Procedures]]
