Description

BACKGROUND OF THE INVENTION [0001] 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. [0002] Recently, 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. [0003] Numerous attempts have been made to combine wireles...

[0011] The invention is an apparatus and method that provides for a handheld wireless communications device capable of simultaneous wireless voice communications and wireless data communications. One aspect of the device provides for a device containing both cellular phone functionality and PDA functionality with dual lines. This provides for a user to simultaneously talk on a cellular phone while accessing data such as the web over a wireless data communication service.

Problems solved by technology

Problems remain in such combinations.

Currently, 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.

This is problematic, as an operator of the device may want to talk to someone over the wireless phone while simultaneously accessing wireless data services such as the web.

Because a shared line is used, both the wireless voice services and the wireless data services are not simultaneously accessible.

Furthermore, this inability to simultaneously access wireless voice and wireless data services may negatively effect service providers in that only one such service is being used although a user may desire to use both services simultaneously.

Therefore, problems in the art remain.
