Disclosed are methods and communication devices for annunciating of missed message alerts, and more particularly for annunciating of missed message alerts according to detection of environmental conditions.
Mobile communication devices, such as cellular telephones, are transported to different locations by their users. In many locations, an incoming communication alert may be audible over the ambient noise. However, there are other locations where an incoming communication alert may not be audible over the ambient noise. For example, in an office building an incoming communication alert is most likely audible. In contrast, on a street having substantial automobile traffic, an incoming communication alert may not be audible over the ambient noise.
To overcome ambient noise for an incoming communication alert, various schemes have been used. For example, increasing the volume of a call annunciator may overcome ambient noise. However, adding additional sound to the ambient noise may not be desirable or actually audible, in particular depending upon the distance between the user and the device. Also, in the event that the ambient noise is persistent, receiving a voice communication while ambient noise is high and attempting to carry on the communication may not be practical since voice communication may be difficult when ambient noise is high.
In a noisy environment an audio signal such as a ring tone to indicate an incoming communication may not be heard by a user if the device's currently selected ringer volume control for the ringtone is lower than the ambient noise. If an incoming communication is not answered or accessed by the user, the device generally generates an otherwise audible missed call alert signal that ends after a predetermined period of time. However, in the noisy environment, an audio signal for a missed call alert may not be heard by the user and thus the user will not be alerted to the missed call. It may be beneficial for the device to postpone generating a missed call alert signal at least until the first quiet period after the missed call. By waiting until the ambient or environmental noise is reduced, an audio alert can become audible to a user. Since the user can benefit from the first quiet period and can be alerted to the missed message alert as soon as it is audible above the ambient noise, a user need not check the display device of the device for missed messages while or after being in a noisy environment. Additionally, it may be beneficial to wait until the ambient noise level of a noisy environment is reduced to carry on a voice communication.
Described are methods and devices for receiving a missed message signal, detecting an ambient noise level, determining whether the ambient noise level is at least at a predetermined ambient noise threshold value based on the detected ambient noise level. When the ambient noise level is determined to be at least at a predetermined ambient noise threshold value the methods and devices include processing missed message alert data of the missed message signal for annunciation of missed message alert data. Processing can include storing the missed message alert data to wait for the ambient noise level to be low enough so that an annunciation of the missed message is audible over the ambient noise. Annunciation of a message alert can be, for example, by audio signal output when the ambient noise is low enough that the alert may be heard by the user.

The mobile communication device 102 can receive and transmit communication by one or more transceivers 104 via a network provider 106, phone to phone, or in any transmission manner.
The network provider 106 may transmit a communication such as a voice communication signal to the mobile communication device 102, however, the user of the device 102 may not answer the call. In that event, the network provider 106 may send a missed call alert signal to the mobile communication device 102, for example, once a message is left in voice mail. Alternatively, the missed message signal can be generated by the mobile communication device. In another situation, the network provider 106 may transmit a communication such as an SMS message signal to the mobile communication device 102. However, the user of the device 102 may not acknowledge receipt of the communication. In that event, the service provider 106 may send a missed SMS message alert signal to the mobile communication device 102. It is understood that a missed call, a voice mail message, SMS message, pushed communication or any other form of received communication by the mobile communication device 102 is within the scope of the term “missed message” as used below.
The mobile communication device 102 can further include a processor or controller 108 configured to carry out instructions, a noise meter 110 coupled to the controller 108 and configured to determine an ambient noise level, a speaker 112 coupled to the controller 108 and configured to provide audio output, a memory 114 coupled to the controller 108 and configured to store modules and missed message signal data, and a transceiver 104 coupled to the controller 108 and configured to receive a missed message and missed message alert data as mentioned above. The device can further include a microphone 118, a keypad 120 and a display 122.
In
The mobile communication device 102 may further include modules 116 including instructions. The modules can carry out certain processes of the methods as described herein. Steps of methods may involve modules and modules may be inferred by the methods discussed herein. The modules can be implemented in software, such as in the form of one or more sets of prestored instructions, and/or hardware, which can facilitate the operation of the mobile station or electronic device as discussed below. The modules may be installed at the factory or can be installed after distribution by, for example, a downloading operation. The modules can include a missed message module 132 including instructions for receiving a missed message signal via the transceiver 104, an ambient noise detecting module 134 including instructions for detecting an ambient noise level by a noise meter 110, a determination module 136 including instructions for determining whether the ambient noise level is at least at a predetermined ambient noise threshold value and a processing module 138 including instructions for processing missed message alert data when the ambient noise level is determined to be at least at a predetermined ambient noise threshold value. The modules can further include an audio message alert module 140 coupled to the speaker 112 for annunciating a message alert based on the missed message alert data by audio output. Additionally, the modules can include a visual signal output message alert module 142 for annunciating a message alert based on the missed message alert data by a visual signal output device such as display 122 and/or device 130. Moreover, the modules can include a timed message alert module 144 coupled to the speaker 112 for adjusting the volume of a message alert after a predetermined period of time.
As mentioned above, the missed message signal can be from any source and can be of any type. Alternatively, the missed message signal can be generated by the mobile communication device. In any event, the method includes detecting an ambient noise level 204 as mentioned above by a noise meter 110 (see
As mentioned above, a ringer volume for the ringtone of the mobile communication device can be pre-selected by a user or can be a default setting. Ringtones are available in variety. If a user is often in a noisy environment, the ringtone may be set to overcome the ambient noise. In any case, the volume of the ringtone may be overcome by ambient noise that prevents a user from hearing the ring. When the detected ambient noise would make the ringtone inaudible, a software flag can be raised as described above to alert the user of the missed call as the noise descends so that a ring may be audible. Determining whether the ambient noise level meets or exceeds a predetermined ambient noise threshold value 206 based on the detected ambient noise level either can result in annunciating the missed message alert 208 or can result in processing the missed message alert data for later annunciation 210.
Processing of the missed message alert data of the missed message signal can continue until annunciation of missed message alert data when the ambient noise level is determined to fall to, or fall below, a predetermined ambient noise threshold value. In one embodiment, the missed message alert data can continue to be stored while the noise meter detects the ambient noise level 204. The loop 212 illustrates that the real-time processing of the missed message alert data may continue until it is determined that the ambient noise level 206 has declined so that the ring may be audible, before annunciating a message alert signal 208. Accordingly, the mobile communication device 102 can deliver a missed message alert signal once ambient noise is reduced.
In another embodiment, when a delayed missed message alert is generated, a mobile communication device may prompt a user to acknowledge a missed message alert. A prompt to acknowledge a missed message alert may be provided, for example by indicia on the display 122 (see
In another embodiment, if ambient noise persists at varying levels and the missed message alert is not acknowledged, then the alert can be repeated. The level of the ambient noise may decrease only temporarily and then may increase past its previous level. It is understood that changes in the ambient noise level that are increasing and decreasing may provide options for varying alerting configurations. Adjustments of the ambient noise threshold value may be made in real-time. Ambient noise may be very loud, in which case an adjustment of the volume of the message alert so that it can be heard by the user may be futile. There may be an amplitude of ambient noise at which an adjustment of the ambient noise threshold value and the volume of the message alert may be effective. A real-time calculation to make such a determination can be made so that the volume of the message alert may be raised or lowered in such a situation.
Turning to
Preferences as to whether to repeat a missed message alert or prompt for acknowledgement can be set by the user or may be set by default settings. Moreover, preferences can be set as to whether to repeat a missed message alert at varying volumes that can be set by the user when considering the circumstances of expected ambient noise. Furthermore, preferences as to whether to adjust the threshold value in real-time may also be available to the user or may be a default setting.
Again referring to
As described above, when the mobile communication device 102 detects noise louder that a preset level and upon a missed call that is received while it is noisy, it can raise a flag to alert, possibly with a special ringtone, just as the noise level descends so that the ringtone is audible to the user which may be at a preset threshold level. That is, the device can wait until the ambient or environmental noise is reduced to benefit from this instant to alert the user of any missed calls during the period where the user has been unable to notice incoming calls.
It may be beneficial to wait until the ambient noise level of a noisy environment is reduced to carry on a voice communication. To overcome the ambient noise level during a communication, the microphone's 118 (see
As mentioned above, a conditions suitability indicator 128 shown on display 122 may annunciate to the user the suitability of the ambient conditions for communication. The suitability of the communication environment is based on at least one of ambient noise level, atmospheric conditions, a state of motion of the mobile communication device or any other environment condition.
As described above, in a noisy environment a ring tone may not be heard by a user. The device or network provider generally generates an otherwise audible missed call alert signal. However, in the noisy environment, an audio signal for a missed call alert may also not be heard by the user and thus the user will not be alerted to the missed call. Also described above, it may be beneficial for the device to wait until the ambient or environmental noise is reduced to generate a missed call alert signal during the first quiet period, and in particular an audio alert so that the audio alert can be audible to a user. Thus, the user can benefit from one or more quiet periods and can be alerted to the missed message alert as soon as it is audible above the ambient noise. Accordingly, a user need not check the display 122 of the device 102 for missed messages while or after being in a noisy environment.
