Abstract
Abstract A paging receiver is disclosed which is compatible with transmissions from analog or digital paging transmitters. The paging receiver has a command structure which permits it to be dynamically programmable to change its functionality including programming of the channels which the paging receiver is to receive. The programmability of the channels permits the paging receiver to be used for making national, regional, remote area, local area, and sublocal area pages, and pages to a group in the local area and to switch from channels which are heavily used during peak paging times to lesser used channels. The paging receiver transmits the paging receiver identification code digits in an order of increasing significance which significantly lessens power consumption for all paging receivers tuned to a particular channel for determining if a page is to be received which prolongs paging receiver battery life. The paging receiver displays the place of origin of pages as either being of local origin or from other areas. The paging receiver antenna is continuously tunable to permit compensation for variation in antenna gain caused by environmental factors which can seriously degrade signal strength.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
200 words
A RF paging receiver for receiving and displaying a place of origin of a page as either originating from an area in which the page is received or originating from another area which is displaced from the area in which the page is received, the page containing a paging receiver identification code identifying the paging receiver, a command controlling display of the place of origin of the page as being either from the area in which the page is received or from the another area, a decoding process used for decoding the page and display of characters within the page comprising: (a) a RF tuner for receiving the commands; (b) a display for displaying a place of origin of a page as either originating from the area in which the page was received or originating from the another area and for displaying the characters within the page accompanying the command; and (c) a controller, coupled to the RF tuner, for decoding the at least one command accompanying the page, controlling the decoding of the page in accordance with the decoded command, the display of the place of origin of the page and the display of the page on the display.
Claim 2
Dependent Claim
200 words
A RF paging receiver for receiving and displaying a place of origin of a page as either originating from an area in which the page is received or originating from another area which is displaced from the area in which the page is received, the page containing a paging receiver identification code identifying the paging receiver, a command controlling display of the place of origin of the page as being either from the area in which the page is received or from the another area, a decoding process used for decoding the page and display of characters within the page comprising: (a) a RF tuner for receiving the commands; (b) a display for displaying a place of origin of a page as either originating from the area in which the page was received or originating from the another area and for displaying the characters within the page accompanying the command; and (c) a controller, coupled to the RF tuner, for decoding the at least one command accompanying the page, controlling the decoding of the page in accordance with the decoded command, the display of the place of origin of the page and the display of the page on the display.
Claim 3
Dependent Claim
59 words
A RF paging receiving in accordance with claim 1 wherein: the command is a local numeric display command causing the display to display that the page originated in the area in which the page was received and the controller in response to the decoded command decoding the page as a numeric page, and the display displaying a numeric page.
Claim 4
Dependent Claim
59 words
A RF paging receiver in accordance with claim 1 wherein: the command is a local alphanumeric display command causing the display to display that the page originated in the area in which the page was received and the controller in response to the decoded command decoding the page as an alphanumeric page, and the display displaying an alphanumeric page.
Claim 5
Dependent Claim
64 words
A RF paging receiver in accordance with claim 1 wherein: the command is a non-local alphanumeric display command causing the display to display that the page originated in the another area displaced from the area in which the page was received and the controller in response to the decoded command decoding the page as an alphanumeric page, and the display displaying an alphanumeric page.
Claim 6
Dependent Claim
64 words
A RF paging receiver in accordance with claim 1 wherein: the command is a non-local numeric display command causing the display to display that the page originated in the another area displaced from the area in which the page was received and the controller in response to the decoded command decoding the page as a numeric page, and the display displaying a numeric page.
Claim 7
Dependent Claim
146 words
A RF paging receiver in accordance with claim 1 wherein: (a) the paging receiver is programmable by a command broadcast to the tuner to store a destination code for controlling reception of pages originating from the another area, pages originating from the another area being transmitted with a destination code as a first character in the page, the destination code signifying that the page originated in the another area and further comprising; (b) a memory for storing the programmed destination code; (c) the paging receiver has a battery which provides operating power to the paging receiver; and (d) the controller compares each page which is received with the stored destination code to determine if a mismatch exists between any transmitted destination code in the page and any stored destination code and if a mismatch exists causes the RF tuner to cease receiving power from the battery.
Claim 8
Dependent Claim
164 words
A RF paging receiver in accordance with claim 6 further comprising: (a) a memory for storing a paging receiver identification code which identifies the paging receiver and wherein: (b) each command has the paging receiver identification code transmitted after the destination code with digits of the paging receiver identification code being transmitted in an order of increasing significance of the digits; and (c) the controller compares the transmitted paging receiver identification code with the stored paging receiver identification code, if a mismatch is found between a transmitted paging receiver identification code digit and a stored paging receiver identification code digit, the control causes the RF tuner to immediately cease receiving power from the battery and if a match is found between all the transmitted and stored paging receiver identification code digits causes the decoding of digits in the page and the display to display the origin of the page as being from the another area and to display the decoded digits of the page.
Claim 9
Dependent Claim
108 words
A paging receiver in accordance with claim 7 wherein: (a) channel programming commands are transmitted to the paging receiver to specify a change in at least one channel to be received by the paging receiver; and further comprising; (b) a channel memory for storing channels to be received by the RF tuner; and wherein (c) the controller decodes at least one channel programming command and causes the storage of the change in at least one channel specified in the at least one decoded channel programming command in the channel memory and causes the RF tuner to change reception of at least one channel stored in the channel memory.
Claim 10
Dependent Claim
19 words
A paging receiver in accordance with claim 8 wherein: the destination code is programmed with the channel programming command.
