Abstract
The present invention provides for directly routing an inbound call to a wireless user element through a servicing mobile switching center (MSC), instead of routing the call to a home MSC and on to the servicing MSC. To facilitate direct routing of a call to a servicing MSC, a tandem switch in the wireline network is given access to the home location register (HLR) database of the wireless network. As such, the tandem switch can determine the MSC servicing a user element, and then route the call to the servicing MSC directly, instead of via the home MSC.
