Abstract: A wireless communication device that has one or more applications resident on a computer platform, a wireless communication interface, a display, and a user interface that, at least, appears on the display and through which a user of the wireless communication device interacts with the computer platform. The display is configured to be selectively controlled by the specific user interfaces of one or more applications resident on the computer platform, and the one or more applications and/or an arbiter that is resident on the computer platform will determine which user interface of the one or more applications resident on the computer platform controls the display based upon a predetermined criteria when the user interfaces compete for control of the display.

Abstract: A wireless communication device that dynamically escalates media transmission handling on the resident computer platform operating system through passing priority data bundles that include media directly from an application programming interface to the wireless communication interface. The application programming interface generates an outgoing priority data bundle including media, and a media handler directs the outgoing priority data bundle directly to the wireless communication interface for transmission without handling of the outgoing priority data bundle by other software layers of the operating system. The same priority handling can be done with incoming data bundles received at the wireless communication interface and being sent to an application programming interface.

Abstract: A system, method, and wireless communication device for sharing media in a group communication among a plurality of wireless communications devices, such as among a Push-to-Talk (PTT) group. A wireless communication device that is a member of the communication group can send group-directed media, such as graphics, multimedia and applications, to other members of the communication group, either during a ongoing PTT communication, or independently therefrom. In one embodiment, a group communication computer device stores information on communication groups on the wireless communication network that includes the member wireless communication devices of one or more communication groups, and receives group-directed media from a sending wireless communication device sends the group-directed media either directly to the other member wireless communication devices of the communication group or stores the group-directed media such that the other member devices can access and download the group-directed media.
