A mobile station communicates with both a cellular network, by which it is assigned a mobile identification number, and to a cordless cellular base station utilizing the same cellular frequency range and communications protocol. The cordless cellular base station is preferably connected to a public switched telephone network and is assigned a landline number. The cordless cellular base station acts as a conduit between the mobile station and the public switched telephone network. When the mobile station comes within range of a cordless cellular base station, it deregisters automatically from the cellular network and register with the cordless cellular base station. Once the mobile station is communicating with the cordless cellular base station, the cordless cellular base station communicates with the cellular network to instruct the cellular network to route all calls for mobile identification number to the cordless cellular base station's landline number. In addition, all calls placed on the mobile station are sent through the cordless cellular base station to the public switched telephone network. When the mobile station severs contact with the cordless cellular base station, the mobile station registers with the regional cellular base station of the regional cellular network. The cordless cellular base station then sends a network forwarding cancellation message to the cellular network to cancel the forwarding of calls for the mobile station's identification number. Once the mobile station is registered with the regional cell, calls to the mobile stations identification number are directly routed by the cellular network to the mobile station.

Embodiments of the present invention relate to a method, apparatus and system for providing personal audio alert messages (PAAM) to a called party and a calling party during a call connection. In response to a call origination by the calling party, a PAAM database may be queried. One ore more personal audio alert message (PAAM) strings may be received from a database in response to the query. A first PAAM string, from the one or more PAAM strings identifying the called party to the calling party, may be returned. The call may be routed to the called party. A second PAAM string and a third PAAM string may be returned, from the one or more PAAM strings, to the called party in the routed call. The call is connected if the called party accepts the call.

A system and method are provided for using Local Number Portability (LNP) and the public switched telephone network (PSTN) trunks as virtual loop-around trunks. Present invention LNP structures and processes redirect calls to avoid the creation of loop-around trunks from calls generated in the local exchange carrier (LEC) requiring services such as prepaid caller and calling party pays. A virtual trunk switch is created using a Switch Control Point (SCP). Telephone numbers requiring special services are ported and stored in a LNP database. Numbers requiring special services are flagged with a LRN that identifies a special service switch which is either an SSP or an SCP. The LRN initiates communication between the local exchange switch and the special service switch. Once engaged, the special service switch protocols create the trunk links. By monitoring these trunk links, the special service switch is able to monitor the in-band communications, and so provide the special services. Similar processes are provided using the LNP to insert either a Service Switching Point (SSP) or an Intelligent Peripheral (IP) in the network trunk to provide services with a fewer number of switch connections.
