ABSTRACT:
A mobility management analysis architecture for call management. Systems and methods are provided for routing of a landline-mobile and mobile-mobile call using a switching network (landline or mobile originating) to serve effectively as the “GMSC/tandem” switching layer for the mobile network, as well as for mobile-mobile calls using an originating switch. When a landline switch issues an local number portability (LNP) query, the response to the query can be intercepted by a preliminary mobility management platform that determines a location routing number (LRN) for a visited mobile switching center (V-MSC) to which a destination mobile handset is currently attached. The LRN for that V-MSC is returned in the LNP response to the switch, which then routes the call to the serving V-MSC based on the LRN. The V-MSC then performs the GMSC (gateway mobile switching center) functionality, for example, for that particular call.
