Abstract

In a radio display pager, a message and a call number of a message destination are transmitted from a speaker in the form of an audible frequency data signal to a paging network. Receiving a transmission radio wave emitted from the network, the pager extracts therefrom a call number and a message to compare these items with the ID call number of the pager, or with the call number of the message destination stored in its memory. When a match results, the call number of the message destination and the message are displayed on an LCD. This guarantees confirmation of the contents of the call number and the message sent from the pager and transmission thereof from the paging network.

Claims

1. A radio paging device having a function of confirming the correctness of a transmitted page, the radio paging device having a device reception address enabling the radio paging device to selectively receive messages from a paging network, comprising:

first means responsive to a completion of a transmission of a transmitted page signal from said radio paging device to said paging network and subsequent receipt of a received page signal from said paging network, the transmitted page signal comprising a given destination address and a given message, said first means being for making a first decision, based on a received destination address extracted from said received page signal from the paging network, concerning whether said received page signal has a destination address which is the same as said device reception address of said radio paging device or the same as said given destination address of said transmitted page signal;

second means responsive to a negative result of said first decision for returning to an operation of accepting a page input;

third means responsive to an affirmative result of said first decision for making a second decision on whether said received page signal has a destination address which coincides with said given destination address and for making a third decision on whether a received message extracted from said received page signal coincides with said given message;

fourth means responsive to a negative result of said second decision for executing an ordinary operation for receiving a page addressed to the radio paging device; and

fifth means responsive to affirmative results of both of said second and third decisions for informing the user of the radio pager device of the correctness of said transmitted page signal.

2. A radio paging device as defined in claim 1, wherein said first means for making a first decision comprises:

a memory area for storing a station address such that the radio paging device is permitted to receive a page having said station address as said destination address;

means operative prior to said transmission of said page for storing said destination address of said page in said memory area; and

means responsive to said completion of said transmission for making a test to see if said received destination address is found in said memory area.

3. A radio paging device as defined in claim 1, wherein said fifth means for informing said user of said correctness of said transmitted page comprises:

means for displaying said given destination address, said given message, and an indication of said correctness of said transmitted page.

4. A radio paging device as defined in claim 3, wherein said fifth means for informing said user of said correctness of said transmitted page further comprises:

means for providing a sound alert.

5. In a radio display pager having a pager reception address enabling the radio paging device to selectively receive messages from a paging network, a method for confirming the correctness of a transmitted page, comprising the steps of:

in response to a completion of a transmission of a transmitted page signal from said radio paging device to said paging network, the transmitted page signal comprising a given destination address and a given message, making a first decision, based on said received destination address extracted from a received page signal from the paging network, concerning whether said received page signal has a destination address which is the same as said pager reception address of said radio paging device or the same as said given destination address of said transmitted page signal;

in response to a negative result of said first decision, returning to an operation of accepting a page input;

in response to an affirmative result of said first decision, making a second decision on whether said received page signal has a destination address which coincides with said given destination address and making a third decision on whether a received message extracted from said received page signal coincides with said given message;

in response to a negative result of said second decision, executing an ordinary operation for receiving a page addressed to the radio display pager; and

in response to affirmative results of both of said second and third decision, informing the user of the radio paging device of the correctness of said transmitted page signal.

6. A method as defined in claim 5, wherein the radio display pager is provided with a memory including an area for storing a station address such that the radio display pager is permitted to receive a page having said station address as said destination address, and wherein said step of making a first decision comprises the steps of:

storing said destination address of said page in said memory area prior to said transmission of said page; and

in response to said completion of said transmission, making a test to see if said received destination address is found in said memory area.

7. A method as defined in claim 5, wherein the step of informing said user of said correctness of said transmitted page comprises the step of:

displaying said given destination address, said given message, and an effect to said correctness of said transmitted page.

8. A radio paging device as defined in claim 7, wherein said step of informing said user of said correctness of said transmitted page further comprises the step of:

providing a sound alert.
