  • the alerts from the continuously repeating information pages can be very annoying to a user.
  • these alerts may be unavoidable using conventional selective call receivers. That is, these alerts cannot be selectively disabled while allowing alerts from other sources. Hence, the user accepts alerts from all sources or from none.
  • the repeated and unwanted pages can accelerate the depletion of the selective call receiver's power source, e.g., the battery.
  • the selective call receiver normally performs the following additional functions: 1) decode the message information, 2) store the decoded message information in memory, and 3) alert the user of the reception of the message.
  • These additional functions consume additional power from the power source, and the continuously repeating pages therefore significantly accelerate the depletion of the power source.
  • the repeated and unwanted pages typically consume precious memory in the selective call receiver which can be used for receiving and storing messages from the more important sources . In some selective call receivers, when memory is completely full with messages, newly arriving messages typically displace older stored messages.
  • the repeated and unwanted pages may cause an interim important message to be deleted from memory before the user has read it.
  • an emergency page may be lost due to the repeated and unwanted pages, resulting in serious consequences.

  • the recovered information signal from the demodulator 104 is coupled to a controller 105 which decodes the recovered information in a manner well known to those skilled in the art .
  • the controller 105 comprises a microcomputer, such as a Motorola, Inc.
  • the manufactured microcomputer e.g., MC68HC05C4, and has a signal processor performing the function of a decoder, which is normally implemented in both hardware and software.
  • the signal processor comprises an address correlator 116 and a message decoder 114, using methods and techniques known to those skilled in the art .
  • the address correlator 116 checks the recovered information signal from the output of the demodulator 104 for address information and correlates a recovered address information with a predetermined address information that is usually stored in the selective call receiver's non-volatile memory 107.
  • the function controller 118 invokes the message decoder 114 to decode the message information that is associated with the correlated address information.
  • Specific status information for each predetermined address information stored in the non-volatile memory 107 is organized in an address and status table in the non ⁇ volatile memory 107.
  • the status information associated with each predetermined address indicates to the function controller 118 whether the particular predetermined address information is currently enabled or disabled, and additionally what function or functions in the selective call receiver to invoke in response to correlating address information to an enabled predetermined address .
  • recovered address information that correlates with an enabled predetermined address information causes the function controller 118 to invoke the message decoder 114 to decode the message information and further to store the decoded message information in message memory 106. In this way, a user of the selective call receiver 100 can retrieve stored messages during normal use, while the selective call receiver typically only decodes messages that are associated with enabled predetermined addresses .
  • the selective call receiver 100 After receiving, decoding, and storing the message information in message memory 106, the selective call receiver 100 typically presents at least a portion of the stored message to a user, such as by a display 108, e.g., a liquid crystal display. Additionally, along with receiving, decoding, and storing the message, an alert is presented to the user via an output annunciator 110.

  • a support circuit 114 preferably comprises a conventional signal multiplexing integrated circuit, a voltage regulator and control mechanism, a current regulator and control mechanism, audio power amplifier circuitry, control interface circuitry, and display illumination circuitry. These elements are arranged to provide support for the functions of the selective call receiver 100 as may be requested by a user.
  • the function controller 118 can determined from the enabled or disabled status information 120 in the non-volatile memory 107 whether to conserve power upon detection of an address information. That is, when-a received and recovered address information correlates with a predetermined address in the non ⁇ volatile memory 107 the function controller 118 checks the status information corresponding to the correlated predetermined address information to determine whether that address is enabled. If the function controller 118 determines that the correlated predetermined address is not enabled then the message decoder 114 is not invoked. Further, the function controller 118 signals a power conservation module 122 to begin conserving power for the selective call receiver 100. The power conservation module 122 signals circuitry in the support circuit 114 to enter a low power mode .
  • a number of power consuming circuits may be directed to a low power or standby mode of operation. Additionally, the signal from the power conservation module 122 may signal, or strobe, the receiver circuitry 103 to a low power mode to conserve power. In this way, when a correlated address is not enabled, as indicated by the associated status information, the selective call receiver 100 may conserve power immediately, while not decoding an associated message and also not storing the message in message memory 106. Of course, the power conservation module 122 will re-enable the receiver and other circuits at some later time. Methods of power conservation strobing in selective call receivers are known to those skilled in the art.
  • the additional power conservation by not decoding and storing message information that is associated with a correlated address information based on an enable status stored in the selective call receiver 100, provides significant advantages over conventional selective call receivers. Specifically, by not decoding and storing the message information the selective call receiver 100 can significantly conserve power. This is particular advantageous when the disabled address information is continuously and repeatedly received by the selective call receiver 100. Further, the controller 105 can inhibit any alerts to the user via the output annunciator 110. By not alerting, again power conservation is maximized.
  • the status information 120 corresponding to each predetermined address information stored in the non-volatile memory 107, therefore, allows the controller 105 to disable functions in the selective call receiver 100, and to conserve power when a correlated address is determined disabled.
  • FIG. 2 illustrates an address and status table in the non-volatile memory 107, according to the preferred embodiment of the present invention.
  • Status information is organized for each predetermined address information.
  • the table comprises addresses 202, of which there are five 212, 222, 232, 242, 252, and status information corresponding to each of the addresses.

  • a user can modify the function status 206 and the enable status 204 for each address in the selective call receiver 100. This user configurability is a significant advantage not available in known selective call receivers. Some examples of user configuration are illustrated in the address status table. For example, the second address
  • the address status table 222 i.e., address 123458, in the address status table has an enable status 224, and an audible 226 alert type. That is, when the address correlator 116 detects the address 123458, the message decoder 114 will decode the message information associated with the correlated address and the function controller 118 will store the message in the message memory 106. Further, the controller 105 will alert the user via an audible alert . For the third address 232 in the address status table, the address is enabled 234 and a silent alert 236 will alert the user that a message associated with the address was received.
  • the fourth address 242 in the address status table has an enable status 244 with the function being a null function 246.
  • This status configuration allows the selective call receiver 100 to decode the associated message and store the message in message memory 106, while not alerting the user. Hence, the message is received and stored into memory 106, while the user is spared any type of annoying alert . At some future time the user would query the selective call receiver 100, such as via the input controls 112 and the display 108, and review any previously received messages, without having been alerted at the time of their reception.

This feature also could be configurable on a per address basis.
  • FIGs. 3, 4, and 5 constitute a flow diagram for configuring the status information 120 for the selective call receiver 100, in accordance with an embodiment of the present invention.
