Description

[Detailed description of the invention] Pagers and radiotelephone devices field of invention TECHNICAL FIELD This invention relates to the paging industry and the cellular radiotelephone industry.

Background of the invention Paging systems are typically one-way wireless communication systems. pager Individuals wishing to communicate with users typically call a central telephone number and contact the central telephone number. Access paging controls. Central paging control is automatic or human It can be operated by an operator. If it's automatic, Callers key in the number assigned to the individual pager they wish to reach. - Manpower. Once that pager is accessed, the caller is paged Leave a voice message for the individual or display it on the pager's display. You can manually key in the phone number to be shown. Some systems also have both Allows both types of paging.

If the central paging control is operated by a human operator, the caller usually informs the operator of the pager number and message. operator then pages the individual, and the paged individual returns to the operator. Relay the message when you call.

Once paged, the individual must find a phone number to respond to the page. I have to get it out. This problem occurs when a paged individual uses a cellular radio phone. This can be solved by carrying it with you. The wireless telephone is used by a mobile user to connect to the cellular communication system. calls can be made or received anywhere within the area covered by the system's antenna. make it possible to do so.

One problem with radiotelephone communications is that the user of the radiotelephone typically makes outgoing calls. You pay not only for incoming calls, but also for incoming calls. That is true. If an unwanted call is made to the radiotelephone, , users of the wireless phone pay for it at a much higher rate than they receive the page. You have to. Therefore, the pager determines which telephone number the called party is calling the callback to. Screens incoming calls to determine which ones to call, thereby reducing charges for unwanted calls. Allows gold to be removed.

Although pagers solve some of the limitations of cellular radiotelephones and vice versa, This allows two to maintain contact while moving around an area. This creates the problem of carrying communication equipment. Therefore both cellular radiotelephones and pagers There is a need for a single device that combines advantages.

Summary of the invention The present invention includes pagers and wireless telephone devices, and includes wireless pagers and cellular wireless telephone devices. combine the calls into one unit, and the unit automatically Can receive multiple pages, communicate cellular phone calls, or turn off and communicate will not participate.

The user has three options to respond to the page using the keypad (127). It has a The recall button (RCL) displays the page on the device display. The CLEAR (CLR) button returns the page to the device display. clear from the scratchpad memory of the (SND) Button is the phone number of the page stored in the scratchpad memory. call the number. If the radiotelephone section (104) powers up without any response from the user. - If it is down, as long as the pager section (102) is powered up. The page data is stored on the microcomputer (121) stack for later use. is memorized. When the radiotelephone section (104) is powered up again, "PAGE" is displayed to notify the user that a page is waiting. page radio telephone section (102) is still powered up. Powering down the pager section (104) will output a unique tone. (102) is still on and therefore using power. indicate.

When the SND, CLR, or RCL button is activated (20 9), everything in the microcomputer stack (121) in the pager section All pages (i.e. phone numbers) are sent from the stack to the pager/phone interface. into the shift register (302) of the face circuit (108), one page at a time. will be moved. First, the memory pointer of the microcomputer (121) Set to indicate the first page of the tack. This page data is PGR Page data on the DATA line is cleared by the bidirectional PGRCLK line. By locking, it is transferred to the shift register (302). Once the page Once the data enters the shift register (302), the radiotelephone section (104) The page data on the data line (PHN DATA) from the shift register (302) for clocking data into the non-volatile memory of the microcomputer (124). The same clock line (PHN CLK) can be used for this purpose. PGRRE The SET line is then pulsed to move the memory pointer to the next page or first page. The next part of the page is moved and the memory transfer operation is repeated (each page has two ). The page data is in the wireless telephone section (104) When clocked into the non-volatile memory of character is removed. The page counter indicates that each page is in the radiotelephone section's memory. is decremented after being clocked in. This will continue until the page counter reaches zero. Continued.

Once the telephone number of each page is stored in the non-volatile memory of the wireless telephone section (104). Once activated, the activated button is processed (210) and the corresponding Decide what to do with the talk number. No matter which button is input The most recent phone number remains in the scratchpad memory in the wireless phone section. The remaining telephone numbers remain in the non-volatile memory. If SND Once the button is activated, the phone number in the scratchpad memory will be called. It will be revealed. If the CLR button is activated, the scratch pad will The phone number stored in non-volatile memory will be cleared for future calls. It remains for serving. If the RCL pu-sauspotan is activated, For example, scratchpad memory is displayed but not called. scratch pad Activate the RCL Button to change the different locations of the harpoon. It can be recalled by activating the number button.

Once all page data has been retrieved from the pager section (102), PAGER0N10FF line is 68HC11 type microcomputer (124 , ) is immediately pulsed high to toggle the D flip-flop (301). pager section (102), thereby turning off the pager section (102). this is a pager Clear the pages stored in the section's microcomputer (121) .
