Abstract

A system and method are disclosed for routing telephone calls directed to a wireless unit located in the wireless network to a landline device located in the landline network. The system utilizes a location register in the form of a service control point (SCP) located in the landline network to store certain information pertaining to landline numbers and respective routing numbers associated with landline devices. The SCP is functionally coupled to a Visitors'"'"' Location Register (VLR) as well as to a landline network element that facilitates the routing of communications to both landline devices and over to the MTSO and its associated Home Location Register (HLR) in the wireless network. The system provides for the registering of the wireless unit with the landline network by the dialing of an administrative number from a landline device and causes the VLR in the landline network to directly communicate with the HLR in the wireless network to keep both the landline and the wireless networks up to date as to the registration status and specific routing for the various subscribers. The system is thereby able to route calls efficiently and to alleviate the tromboning effect that often occurs when calls are redirected from a wireless unit to a landline device.
