Abstract

Both paging and cellular radiotelephone functions can be combined in a small, lightweight, single device by sharing most circuitry. The apparatus can receive paging signals simultaneously with radiotelephone signals because of dual receivers (105 and 110). When the paged party receives a page, an alert tone, a vibration, a visual indication, or a voice message is used to alert the party. Information extracted from the paging signal can be stored in memory (101) for later use. The paged party can select among messages stored in memory. If a message contains a telephone number, the paged party can call that number using the radiotelephone function at the touch of a button. The apparatus'"'"'s keypad (102) can be used to program the paging function receiving frequency, identification code and type of paging system.

Claims

1. An integrated paging and radiotelephone apparatus with integral keypad for entering data, comprising:

a) first receiving means for receiving radiotelephone signals;

b) second receiving means for receiving paging signals;

c) transmission means for transmitting radiotelephone signals;

d) electro-audio transducer means, coupled to the first and the second receiving means, for generating an indication in response to the radiotelephone signals or the paging signals, the electro-audio transducer coupled to the first receiving means through first controllable gating means and the second receiving means by second controllable gating means;

e) a shared memory for storing data from the integral keypad and the received paging signals;

f) a processor, directly connected to the first receiving means, the second receiving means, the transmission means, and the first and second controllable gating means, for producing radiotelephone control signals and controlling the first and second controllable gating means;

g) first indicating means for displaying information corresponding to the received paging signals and the radiotelephone control signals; and

h) second indicating means for announcing the received paging signals and the received radiotelephone signals.

2. The apparatus of claim 1 wherein the second indicating means is vibrating means.

3. The apparatus of claim 1 and further including antenna means coupled to the first receiving means, the second receiving means, and the transmission means.

4. An integrated paging and radiotelephone apparatus comprising:

a) first receiving means for receiving radiotelephone signals;

b) second receiving means for receiving paging signals;

c) transmission means for transmitting radiotelephone signals;

d) electro-audio transducer means, coupled to the first and the second receiving means, for generating an indication in response to the radiotelephone signals or the paging signals, the electro-audio transducer coupled to the first receiving means through first controllable gating means and the second receiving means by second controllable gating means; and

e) a processor, directly connected to the first receiving means, the second receiving means, the transmission means, and the first and second controllable gating means, for producing radiotelephone control signals and controlling the first and second controllable gating means.
