  • Patent number: 10158765
    Abstract: Services are provided based on the locations, rather than the NPA.NXX identifiers, of called and calling parties. Party location based services can be provided to the called party, to the calling party, or both. Services can include an indication of the location of each party. Services also can include an indication of charges as determined by the location of the parties, rather than the NPA.NXX identifiers. Services can be provided if the parties are using a mobile communications devices, such as a cellular phone, wireline systems (e.g., landline phones), or a combination thereof. In an example configuration, location can be provided in a hierarchy of various levels of accuracy/precision. Different levels can be representative of different resolutions of geography. An example system for facilitating party location based services includes a signaling system number 7 (SS7) network.

  • Patent number: 8898770
    Abstract: A method and apparatus for accessing contact records in an electronic device with multiple operation perimeters is provided. When accessing contact records from within one operation perimeter, only contact information accessible from that operation perimeter is retrieved. An option is provided to also access contact records of an alternative operation perimeter. If the alternative operation perimeter has a higher security level than the current operation perimeter, a password or other authorization may be required. The contact records may be accessed, for example, to find information for an outgoing communication, to identify information associated with an incoming communication, or to edit a contact record.

  • Patent number: 8559608
    Abstract: A location of a calling party is provided to a called party. The location can be provided if the calling party is using a mobile communications device or a wireline system. The location of the calling party can be provided in a hierarchy of various levels of accuracy/precision representative of different geographies provided by a service provider. The choice of levels for each received call or all received calls can be configurable by the called party. The called party may subscribe to a service that provides the location information. The called party may have the option to receive location information on a per call basis. The calling party may be asked for consent. Location information can be provided for any appropriate type of call, such as, for example, voice calls, text based calls (e.g., SMS messages), or the like. In an example configuration, the SS7 network is utilized.
