  "title": "Cellular telephone, personal digital assistant with dual lines for simultaneous uses",
  "abstract": "The present invention includes a method and apparatus for a handheld personal communications device capable of simultaneous wireless voice communications service and wireless data communications service. The invention includes providing wireless voice communications service to a first line of a handheld personal communications device and simultaneously providing wireless data communications service to a second line of the handheld personal communications device.",
  "claims": [
    "7. A handheld personal communication device capable of simultaneous wireless voice communication and wireless data communications comprising: a housing; a first wireless radio transceiver disposed within the housing for operative voice communication across a first communication channel and for operative data communication across a second communication channel; a sensor operatively connected to the first wireless radio transceiver for transducing voice sound information; a speaker operatively connected to the first wireless radio transceiver for producing voice sound information; an intelligent control operatively connected to the first wireless radio transceiver for sending and receiving data; and a display operatively connected to the processor capable of displaying a visual representation of data received over the second communications channel; wherein the second communication channel provides for receipt of wireless data to provide wireless web access simultaneously with voice communication.",
    "8. A method for providing wireless voice communication service to a handheld personal communication device, comprising: providing wireless voice communication service to a first line of the handheld personal communication device; simultaneously providing wireless voice communication service to a second line of the handheld personal communications device; charging for the voice communication service to the first line; and charging for the voice communication service to the second line.",
    "9. The method of claim 8 wherein the wireless voice communication service is selected from the set comprising PCS, CDPD, AMPS, and GSM.",
    "10. The method of claim 8 wherein the first line is associated with a first communications channel and the second line is associated with a second communications channel.",
    "11. The method of claim 8 further comprising the handheld personal communication device.",
    "12. A method for providing wireless communication service to a handheld personal communication device, comprising: providing wireless communication service to a first line of the handheld personal communication device; simultaneously providing wireless communication service to a second line of the handheld personal communication device while providing wireless communication service to the first line of the handheld personal communication device; charging for the wireless communication service to the first line; and charging for the wireless communication service to the second line.",
    "13. The method of claim 12 wherein the wireless communication service to the first line is a voice communication service.",
    "14. The method of claim 13 wherein the wireless communication service to the second line is a data communication service.",
    "15. The method of claim 12 wherein the handheld personal communication device is a phone.",
    "16. A method of providing communication service to a phone, comprising: simultaneously providing a first and second channels of communication to the phone and charging for both communications over the first channel and communications over the second channel.",
    "17. The method of claim 16 wherein the first channel provides for wireless web access and the second channel provides for voice communications."

  "description_excerpt": "The present invention relates to personal communications systems such as those that combine the functionality of a personal digital assistant with wireless voice communications, such as cellular phones or satellite phones.\n\nRecently, numerous efforts and attempts have been made to combine cellular phones with personal digital assistants. Although the terms cellular phone and personal digital assistant are used throughout, it is to be understood that both terms should be construed broadly. Cellular phones include satellite phones and other technologies for providing wireless voice communications. PDA is used to refer to handheld computers which have become known as personal digital assistants, handheld devices with organizer functions, and similar type devices. For example, Smart phones, or other cellular phones that offer wireless web services are considered to have PDA functionality.\n\nNumerous attempts have been made to combine wireless voice services with wireless data services such as wireless web access services. Advances in the field have provided for the creation of devices that contain the functionality of a PDA with wireless voice communications. Problems remain in such combinations.\n\nCurrently, such solutions that combine PDA functionality with cellular phones suffer from a number of problems that do not occur when separate devices are used. One of the greatest problems recognized by the Applicant is that these prior art solutions do not provide for wireless data services to be used simultaneously with wireless voice services.",
