  • Patent number: 7894814
    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.
    Type: Grant

  • Patent number: 7130628
    Abstract: Systems and methods are presented in which a routing number for telecommunication environments are stored in both a wireless network and a landline network. By storing the routing number at both the wireless network and the landline network, a “tromboning” effect is reduced, thereby providing greater efficiency.
