A wireless communication terminal is configured for enabling a user to receive and transmit video images as well as receive and transmit audio or speech signals associated with the user of the terminal and another user at, for example, a remote location. The received video image is obtained from a video image signal received over a radio frequency communications link established between the wireless communication terminal and a cellular base station. This received video image is displayed in a video image display conveniently associated with the wireless communication terminal. The transmitted video image signal may be that of the user of the terminal, of a scene within the field of view of the video camera or of text either coupled to the terminal through one of many well known data interfaces, or an image of text as captured by the camera. This transmitted video image signal is obtained from a video camera associated with the wireless communication terminal and then transmitted over the radio frequency communications link established between the wireless communication terminal and the cellular base station for displaying in a remotely located video image display. |

DETAILED DESCRIPTION Shown in FIG.
1 is a schematic representation of a mobile radio telephone communication configuration which illustratively includes a mobile telephone switching office (MTSO) 100 adapted to link a wireless communication terminal or mobile radio telephone set 200 into a regional or nationwide telephone network (not shown).
A cellular base station 102, coupled to the MTSO 100 via a bi-directional voice and data communication link 103, is arranged to be in radio frequency communication with the mobile radio telephone set 200 via a radio frequency (RF) antenna 104.
Also shown in schematic form is a cellular communications service provider center 105 adapted to be coupled to the MTSO 100 via another bidirectional voice and data link 106.
The service provider center 105 includes, inter alia, a telephone private branch exchange (PBX) 107, and a service attendant station 108 coupled to the PBX 107.
The telephone switching office, base station 102, and PBX 107 all may be part of an Autoplex.
RTM.
1000 system such as that described in U.

As shown, the mobile radio telephone set 200 comprises a handset unit 201 with an RF antenna 202, a keypad 203 and a dial display 204.
The mobile radio telephone set 200 also comprises a portable base unit 205 that is shown illustratively connected to the handset unit 202 by way of a cord 207 for providing the necessary data transfer between these two units.
Alternatively, a cordless radio frequency video link may be used in communications between the handset unit 201 and the portable base unit 205.
As appreciated by those skilled in the art, such technique is known and presently available commercially in many remote video monitoring systems, an example of which is the video-based baby monitor available from Fisher-Price.
Included in the portable base unit 205 is a display 210 for showing a received visual image and also a camera 211 for capturing a visual image for transmission to a remote display device (not shown) through the radio frequency communication with the cellular base station 102
