Radio transceiver having fixed calling capacity
First Claim
1. In a cellular, communication system comprised of a plurality of base stations coupled to a wireline network having fixed sites connected thereto, a radio transceiver having transmitter circuitry operative to transmit a fixed number of call sequences to a base station of the cellular communication system to effectuate thereby telephonic communication between the radio transceiver and fixed sites of the wireline network associated with the call sequences transmitted by the transmitter circuitry, the combination with the transmitter circuitry of:
- means forming a first memory location for storing a first call sequence therein;
means for initiating transmission by the transmitter circuitry of the first call sequence stored in the first memory location;
means forming a second memory location for storing a second call sequence therein; and
means for initiating transmission by the transmitter circuitry of the second call sequence stored in the second memory location only after effectuation of telephonic communication between the radio transceiver and the first fixed site and termination of telephonic communication therebetween.

Abstract
A cellular phone having a fixed calling capacity limiting use of the phone to emergency situations. Two call sequences are stored in memory permitting telephonic communication with only the two fixed sites associated with the two call sequences. Telephonic communication must be effectuated with a first fixed site, and then terminated, prior to effectuation of telephonic communication with a second fixed site. Telephonic communication with a second fixed site is permitted during a predetermined, limited time period.

14. A radio transceiver operative in a cellular communication system comprised of a plurality of base stations coupled to a wireline network having fixed sites connected thereto, each of the fixed sites being associated with a particular call sequence, said radio transceiver comprising:
-
transmitter circuitry for generating and transmitting a modulated signal; means forming a first memory location for storing a first call sequence therein; means for supplying a signal representative of the first call sequence stored in the first memory location to the transmitter circuitry to initiate transmission of a modulated signal representative of the first call sequence, thereby to effectuate telephonic communication with the first fixed site; means forming a second memory location for storing a second call sequence therein; means for supplying a signal representative of the second call sequence stored in the second memory location to the transmitter circuitry to initiate transmission of a modulated signal representative of the second call sequence, thereby to effectuate telephonic communication with the second fixed site only after effectuation of telephonic communication between the radio transceiver and the first fixed site and termination of telephonic communication therewith; and means for supplying power to the transmitter circuitry. - View Dependent Claims (15, 16)

17. In a radio transceiver having transmitter circuitry and receiver circuitry, and operative in a cellular communication system comprised of a plurality of base stations coupled to a wireline network having fixed sites connected thereto, a method for effectuating, sequentially, telephonic communication between the radio transceiver and first and second fixed sites, the first and second fixed sites being associated with first and second call sequences, respectively, said method comprising the steps of:
-
storing a first call sequence in a first memory location; storing a second call sequence in a second memory location; initiating transmission of the first call sequence stored in the first memory location by the transmitter circuitry of the radio transceiver to effectuate thereby telephonic communication between the radio transceiver and the first fixed site; terminating telephonic communication between the radio transceiver and the first fixed site; and initiating transmission of the second call sequence stored in the second memory location by the transmitter circuitry of the radio transceiver to effectuate thereby telephonic communication between the radio transceiver and the second fixed site only after effectuation of the telephonic communication between the radio transceiver and the first fixed site and termination of telephonic communication therebetween. - View Dependent Claims (18)
