<p>A platform ('Ulyssees') supports a signalling relay function (SRF), a number portability location register (NPLR), and a number portbaility database (NPDB). The signalling relay function receives signals from an MSC and routes as appropriate for number portability and with relevant protocol conversion. The relay translates a MAP operation between networks so that a call is routed directly from an MSC of an originating network to an MSC of the destination network.</p> |
