  • Patent number: 8060113
    Abstract: A location visit detail service, typically provided by a wireless carrier to a subscriber includes a portable wireless device, a location identification means and a central processor. The central processor periodically receives location data generated by the location identification means. The central processor data transforms the location data into time and position data pairs that identify the location of the portable wireless device at a particular time. Through a geographic information system database, the position data is converted to street address data. The details data is provided by the wireless carrier to the subscriber, which can use the details data to provide a summary report describing the activity of the service person. This summary report can be used for preparation of bills or for gathering statistics on (individual or group) service person efficiency. Alternatively, the wireless carrier can prepare the report that is then transmitted to the subscriber.

  • Patent number: 7711102
    Abstract: A Service Control Point (SCP) has a call list associated with the main telephone number of a called party. When a calling party attempts to contact the called party by calling the main number, but cannot reach the main number, a Service Switching Point (SSP) fires a trigger. One trigger is a T_No_Answer trigger, which is fired in response to a call to the main number that is not answered within a predefined number of rings. Another trigger is a T_Busy trigger that is fired in response to a call to the main number that is made when the main number is busy. Each trigger causes the SCP to access the call list and to cause the SSP to ring an alternative telephone number associated with the main telephone number. If this attempt to reach the called party also fails, then the SSP again fires the trigger and an attempt is made to connect the calling party to the next number on the call list.

  • Patent number: RE41692
    Abstract: A system for obtaining location data of calling parties for telephone calls provides location data for display by a called device. Through reception of the name, telephone number, or other calling party identifier as is done through the conventional caller ID service, the called device formulates a query to a database containing location data for calling parties. Existing advanced intelligent network infrastructure may be used to provide caller ID data to the called device, and the called device uses this caller ID data to formulate the query to the database. Additionally, the called device may have access to multiple databases containing location data and may detect an appropriate database to query based upon analysis of the caller ID data that has been received.
