DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention This application relates to wireless communication devices, and more particularly, to wireless communication devices having an intelligent warning device that generates a warning signal optimized for the environment of the wireless device.

[0002]

2. Description of the Related Art A radio communication apparatus, hereinafter referred to as a "wireless apparatus", employs various warning methods to notify a user of a radio apparatus that a desired incoming signal has been received. For example, a wireless telephone alerts the user when an incoming call signal is received, and a pager alerts the user when an incoming page signal is received. Generally, such alert schemes include audible, visual and tactile alert generators.
Audible alert generators are typically constructed using an acoustic transducer, also called a ringer, ie, a speaker. The visual alert generator is typically configured using a display or a separate display. Tactile alert generators are typically constructed with an axially offset counterweight driven by a motor to create a sense of vibration. However, the sound generated by the audible warning generator can be annoying to others in low ambient noise levels. Further, the generated sound may not be heard by the user in an environment with a high ambient noise level.

[0003] The visual display generated by the visual alert generator may be unnoticed by the user for a period of time before the user actually sees the visual display. Thus, an audible alert generator is typically used as a primary alert, and a visible alert generator is typically used as a secondary or duplicate alert. The haptic sensations generated by the haptic alert generator may be unnoticed by the user when the user is not wearing a wireless device or is not tightly coupled to the user in any way. Thus, haptic alert generators are typically used in environments with low ambient noise levels and do not disturb others in the area or in environments with very high ambient noise levels, and provide audible alerts. Alert users when they can't hear. Some wireless devices provide an advanced ringing scheme and use a ringing tone that starts at a low volume and continuously increases in volume until the generated sound reaches maximum volume or the user answers the call . Other devices use a mixed alerting scheme for incoming calls and messages, such as generating a tactile sensation for a scheduled time and then generating a sound for another scheduled time. Used. Missing calls, messages and reminders due to very high ambient noise levels, or because the wireless device is in a purse, luggage or other carrying accessories, and is not aware of the warning There are many.

US Pat. No. 5,956,626, the contents of which are incorporated in this application, discloses various types of available sensors and introduces electromagnetic proximity sensors. Motion sensors, capacitance sensors (infrared sensors), proximity sensors, to name a few, eddy current sensors, variable magnetoresistive sensors, Hall effect sensors,
There are many sensors, including reed switch sensors, reflective optical sensors, metal detection sensors, and microwave sensors. However, sampling the noise level surrounding the wireless device,
An intelligent alert that "listens" to the wireless device's environment by generating either a tactile, visible, or audible alert signal based on a set of programmed instructions that can be executed by a central processing unit within the wireless device. No equipment. In addition, existing alerting devices include a number of sensors, a received signal strength indicator (RSSI), a cellular network ID and a common radio link receiving indicator (ie, Bluetooth-short) to determine a preferred alert signal. Nothing uses distance, cable-substitute wireless technology). Accordingly, there is a need for a wireless device having an intelligent alert device that devises the definition of an optimal alert sequence from the operating environment of the wireless device.

[0005]

Define the definition. The program of instructions may include a neuron network algorithm that incorporates a self-learning process into the wireless device to continuously improve the optimization sequence. Thus, the central processing unit is responsive to the definition of the reflected signal and the alert sequence to determine which alert signal is optimal in a given environment.

The advantages of the present invention include, but are not limited to, the reliability of an intelligent alert device that generates optimal alerts and minimizes missed calls, messages and reminder-alarms in a given environment of a wireless device. Is provided. Even if the device is in a high or low ambient noise environment or hidden in carrying accessories, unnoticed warnings are minimized. Furthermore, in an environment where the ambient noise level is low,
No nuisance or unwanted warnings are issued. For a more complete understanding of the invention and its advantages, reference is now made to the drawings. Throughout the drawings, similar parts have the same reference numerals.

The menu may also include an option to modify a predetermined last alert response based on the environment of the wireless device. The user can select a preferred response and store this response so that future decisions include the user's input.
Wireless device 100 has a central processing unit 114 connected to a user interface 116. The user interface 116 includes a display 118 and a key set 120, both connected to the central processing unit 114. Wireless device 100 may be a portable wireless telephone, a cordless wireless telephone, a page / message device, and any other portable device that communicates with another device such as a telephone (ie, as a one-way or two-way communication device). In this specification, "wireless device" refers to any of these, as well as their equivalents. Optionally, user interface 116 may include a conventional microphone 110 and speakers 128 connected to central processing unit 114 via coder / decoders (codecs) 112 and 126, respectively.

[0009] The key set 120 is constructed using any suitable means, such as a push button keypad, a touch screen, or the like. The display 118 is constructed using any suitable commercially available device, such as a liquid crystal display (LCD), a light emitting diode (LED) display, and the like. Central processing unit 114 may be implemented using one or more suitable microcontrollers, microprocessors, or digital signal processors such as the Texas Instruments TMS320C54X (TM) DSP core. Central processing unit 114 may be programmable, in which case it includes a programmable storage device (not shown) that materializes a program of instructions that the central processing unit may execute. Instead,
Central processing unit 114 may be implemented with a microcontroller coupled to a separate programmable storage device, such as a digital signal processor, that materializes a program of instructions that central processing unit 114 may execute. The memory 102 for storing the noise threshold coefficient is connected to the central processing unit 114. Further, a plurality of alert generators 122 _i -122 _n are connected to the central processing unit 114. These may include a display mechanism such as a tactile alert generator 122 _i , an audible alert generator 122 _j or a display 118. Tactile warning generator 122 _i includes a transducer, is rotated by driving the offset weight (not shown), thus the motor for generating vibration (not shown), or any other suitable for It can be configured using means. The audible alert generator 122 _j can be connected to the central processing unit 114. Generally, antenna 108, transmitter 104, receiver 106, speaker 128, microphone 11
0, tactile alerting device 122 _i and audible warning device 122 _j are all well known individually, except when necessary to facilitate an understanding of this invention, it would not require explanation in particular. In addition, the general operation of a radiotelephone is well known and will not be described unless necessary to make the invention easier to understand.

[0010] The transceiver of the wireless device includes a transmitter 104 and a receiver 106. Generally, the central processing unit 114
Outputs a signal to the transmitter 104 and the antenna 108
Modulate this signal for transmission over. Transmitter 10
4 is a control signal, a signal detected by the microphone 110, or an external device (not shown).
And any other signals to communicate with. Antenna 1
08 is demodulated by the receiver 106 and the resulting signal is processed by the central processing unit 114.
Is input to Alternatively, the central processing unit 114 may demodulate the signal. For this purpose, the central processing unit 114 outputs these signals to the speaker 128 or uses these signals in the control process. In operation, central processing unit 114 detects an incoming call at decision block 154 (FIG. 1b) and initiates an optimal warning subroutine 150. The central processing unit 114 controls the coder 112 connected to the microphone 110 to sense the environment or to receive the analog signal “listened” by the microphone 110, as shown in block 156. After this, block 158
The encoder 112 converts an analog signal into a digital signal as shown in FIG. As indicated by block 160,
In response to the digital signal, the central processing unit 114 searches the memory 102 for a threshold coefficient. Block 162
Illustrates that the central processing unit 114 processes a digital signal by executing a program of instructions residing in a programmable storage device (not shown). Decision block 164 indicates that central processing unit 114 determines whether the processed digital signal satisfies a predetermined criterion for an audible alert based on the predetermined coefficient and program of instructions. If so, block 166 indicates that the central processing unit 114 sends a control signal to an audible alert generator 122 _j connected to the speaker 128 to generate an audible alert signal. It is believed that the volume and frequency of the audible alert signal can be determined based on a determination of the processing of the program of instructions at block 162. According to the indication at block 164, if the optimal warning signal is not an audible warning signal,
Central processing unit 114 determines whether the haptic alert signal is best, as indicated by decision block 168. If so, the central processing unit 114 sets the tactile alert generator 11
Send a control signal to 2 _i to generate a haptic alert signal, as indicated by block 170. Alternatively, central processing unit 114 can send a control signal to display device 118 to generate a visible warning signal, as shown in block 172. Thus, once the alert signal is generated, central processing unit 114 processes the call or message, as shown in block 174.

Alternatively, if the response to decision block 154 is negative, an optional block similar to block 156 is implemented so that central processing unit 114 periodically schedules coder 112 and microphone 110. It is also conceivable to control at intervals to sense the environment or microphone 110 to receive "listened" analog signals. Because of this,
Block 156 is deleted because the sensor readings are continuously updated and there is no need to determine environmental information. Thus, the characterization of the environment is not initiated solely in response to an incoming call. The existence of previous estimations and measurements helps to improve the reliability of the device 100.

In the user mode of operation shown in FIG. 1c, the user can "train" the response of the wireless device 100 according to his preferences. The display device 118 can display a menu of information that can be selected.
The menu selected for training the definition of an optimal alert sequence may include default set and reset features, so that after a series of questions have been answered using the select key, All default values can be set. As indicated by block 181, the central processing unit 114 is waiting for user action. The user
As indicated by block 182, one may choose to change the definition of the alert sequence. If the user wishes to fully define the alert sequence, as shown at block 183, the central processing unit 114 presents an alert sequence request routine on the display 118, which routine is "quiet", "noisy", " A standard set of questions is asked to the user to define different alerts for different types of environments, such as "daytime", "nighttime", "belt", "wallet", etc. The settings for the new alert sequence definition appear on the screen. If the user wants to change only the response of the lowest alert signal, the user can choose to change the definition of the lowest alert sequence from the menu, as shown in block 184. As shown in block 185, the central processing unit 114 passes the user through a lowest alert sequence request routine that asks the user a standard set of questions to determine different alert signals for the lowest sensing environment. Can change the bottom warning signal response. The new settings are displayed on the display device 118. If the user so desires, decision block 186
The user can choose to save the new settings, as shown in. As shown in blocks 187, 188 and 189, the new settings can be stored in a default file or a user order file. Optionally, as shown in blocks 190 and 191, help can be selected from a menu, which initiates a help display. Alternatively, the user can exit the menu, as indicated by block 192. Thus, the user selects the preferred response and saves this response whenever the wireless device is in the same environment that generated this lowest alert response, so that the user's decision includes the user's input. You can do it.

An advantage of the present invention is, but is not limited to, providing a reliable wireless device having an intelligent alert device. Based on the definition of the optimal alert sequence introduced in this intelligent alert device, the probability of a user missing a call, message or reminder is reduced. In addition, low ambient noise levels or other environments do not cause disturbing or undesired warnings. It is also contemplated that the central processing unit can process a program of instructions for speech recognition. The central processing unit can create an optimal warning method based on the recognizable pattern of the voice. For example, when the environment of the wireless device senses the user's voice, the central processing unit makes a determination as to which variable initiates a warning signal.

A control signal is sent to the control unit 4 to convert the analog signal into a digital signal. A programmable storage device readable by the central processing unit 218 has a program of instructions that the central processing unit 218 can execute. In response to the digital signal, central processing unit 218 processes the digital signal based on the stored threshold coefficients, various sensor data and empirical intensity and position data, and determines a preferred alert signal. Therefore, the central processing unit 21

In another aspect of the invention, central processing unit 218 sends a control signal to speaker 238 to generate a signal tone in response to a transmission signal from an external device (not shown). Further, the central processing unit 218 sends a control signal to the encoder 214 to convert an analog signal detected by the microphone 212 into a digital signal. The central processing unit 218 processes the digital signal using the stored threshold coefficient and instruction program to determine a preferred warning signal and to generate at least one control signal for the selected warning signal generator. send.

The wireless device 200 has a central processing unit 218 connected to a user interface 226. The user interface 226 has a display 228 and a key set 230, both connected to the central processing unit 218. Wireless device 200 may be a mobile phone, a cellular wireless phone, a cordless wireless phone, or any other portable device that communicates with another device, such as a telephone, and a “wireless device” herein refers to Refers to each and its equivalents. Optionally, user interface 226 may include a conventional microphone 212 and speakers 238 connected to central processing unit 218 via coder / decoder (codec) 214 and 236, respectively. The key set 230 is a push button
Configured using any suitable means, such as a keypad, touch screen, and the like. Display 228 is constructed using any suitable commercially available device such as a liquid crystal display (LCD), light emitting diode (LED) display, and the like. The central processing unit 218 may be implemented using one or more suitable microcontrollers, microprocessors, or digital signal processors such as the Texas Instruments TMS320C54X ™ DSP core. Central processing unit 218 may be programmable, in which case it includes a programmable storage device (not shown) that embodies a program of instructions that the central processing unit can execute. Alternatively, central processor 218 may include a separate programmable storage device, such as a digital signal processor, that materializes a program of instructions that central processor 218 can execute.

To supply. A plurality of alert generators 232 and 234 are connected to the central processing unit 218. This can be a tactile alert generator 232, an audible alert generator 234 or the display 22.
8 may include the same display mechanism. The tactile alert generator 232 may include a transducer, a motor (not shown) that drives and rotates a staggered weight (not shown), thus producing vibration, or any other suitable means. It can be configured using: An audible alert generator 234 may also be connected to the central processing unit 218. The device 200 may include an intelligent alert cancellation feature, which may be activated according to a human interface including, but not limited to, a keypad, a voice interface or a touch screen. ing. Thus, the human interface allows the user to immediately disable or enable the intelligent alert feature. The transceiver of the wireless device includes a transmitter 208 and a receiver 210. Typically,
The central processing unit 218 outputs a signal to the transmitter 208, which modulates the signal for transmission via the antenna 209. The signal output to the transmitter includes a control signal, a signal detected by microphone 212, or any other signal that communicates to an external device (not shown). The signal detected by antenna 209 is demodulated by receiver 210, and the resulting signal is input to central processing unit 218. The central processing unit 218 outputs these signals to the speaker 238, or uses the signals in the control process.

In the time division duplex (TDD) system, monitoring of a received signal strength indicator (RSSI—not shown) is a standard used in digital wireless communication, ie, a standard for determining characteristics of a received signal. Method. Even in the analog method, monitoring of the received signal strength indicator is a standard method for determining the characteristics of the received signal. The received signal strength of the RF signal can be measured using RSSI at a predetermined number of test points for a central transmitter (ie, a cellular base station tower—not shown). In addition, the exact location of the device can be determined by a Global Positioning System (GPS) receiver (not shown) that can be provided within wireless device 200. Alternatively, the position data can be detected using the control channel of the communication device, as is known. Thus, using empirical signal strength and position data retrieved using control channels and GPS and RSSI receivers, central processor 218 can determine an optimal alert sequence. Further, as is known to those skilled in the art, if the system identification (ID) is valid for a cellular network, a cellular service indicator (not shown) within the wireless device may be Indicates whether the device is in home mode or roam mode. The control packet in the packet header of the transmitted signal received by the receiver 210 has a cellular network identification (ID). Thus, in addition to empirical signal strength and RSSI receiver position data,
The central processing unit 218 can use the cellular network identification to define an optimal alert sequence. By using both the RSSI and the cellular network ID, the probability of a correct decision is increased by distinguishing the two places where the user is typically located. Substantially different R, especially when all other properties are similar
It may be advantageous to use the SSI level or a different network ID.

The radio link transceiver is the transmitter 204
And a receiver 206. Central processor 218 outputs a signal to wireless link transmitter 204, which modulates the signal for transmission via antenna 205. The signals output to the wireless link transmitter 204 include control signals and any other signals for communicating with external devices (not shown). The signal detected by the antenna 205 is demodulated by the radio link receiver 206, and the resulting signal is input to the central processing unit 218. The central processing unit 218 uses this signal in its control process. A variety of common wireless links can be used to construct a transceiver including a transmitter 204 and a receiver 206.
One wireless link that is particularly advantageous is the Bluetooth wireless link, a short-range cable replacement wireless technology. Systems with Bluetooth wireless technology can use the transmitted signal to identify a fixed access point with which the device 200 communicates, and thus determine the location of the device 200. Based on this location, the central processing unit 218
Can determine the optimal alert sequence. A Bluetooth wireless link allows data synchronization between a wireless device and a peripheral device such as a personal computer (PC) or personal computer assistant (PDA). Bluetooth also enables communication between wireless headset devices and wireless devices.
In addition, Bluetooth wireless link technology allows wireless devices to be
Can work as a dial-up network for the telephone, thus eliminating the need for a cable between the telephone and the PC.

Generally, an antenna 209, a transmitter 20
8. The receiver 210, the wireless link transmitter 204, the wireless link receiver 206, the speaker 238, the microphone 212, the tactile warning device 232, and the audible warning device 234 are all individually known and facilitate understanding of the present invention. It is considered that no further explanation is necessary other than necessary. Further, the overall operation of the radiotelephone is well known and will not be described unless necessary to facilitate understanding of the invention. The operation will be described. As shown in FIG.
8 detects the incoming call at decision block 304 and initiates an intelligent alert subroutine 300. Central processing unit 2
Using the microphone 18 and the microphone 212, the level, spectral distribution and properties of the environment are determined by echo / acoustic processing. This includes the central processing unit 218 sending a signal to the speaker 238 to generate a signal tone, as shown in block 306. As shown in block 308, the central processing unit 218 controls the coder 214 connected to the microphone 212 to sense the environment or
2 receives the "listened" analog signal. Thereafter, the encoder 214 converts the analog signal to a digital signal, as shown in block 310.

The real time clock 202 (including the date) is set to 2
Use for one purpose. 1. 1. Set a user-defined alert based on the time of day (if so configured); The amount of light expected at that time and place is estimated and compared with the actual light measurement result. In some places, natural sunlight is expected during certain times of the day. Therefore, the central processing unit 218
, The time at which the real-time clock 202 relays,
The light threshold is determined from a preset location selected by the user and stored in the memory 216.
Using this light threshold, the central processing unit 218 can determine whether the wireless device is in a dark, confined container such as a purse or pocket.
To determine whether the wireless device 200 is wrapped in a purse, for example, and issue a warning accordingly, the program of instructions executed by the central processing unit 218 may include a predetermined threshold coefficient with appropriate statistical weights and Combine to reach the highest probability conclusion. For example, if the level of light from the sensor is indicative of total darkness, but the real-time clock 202 is relaying the time of 5:00 pm in the summer of Dallas, Texas, this means that the wireless device 200 has a wallet, Increase the likelihood of being in a briefcase or other carrying accessory. In response to the digital signal, the central processing unit 218 retrieves a threshold coefficient from the memory 216, as shown in block 314. Block 316 shows that the central processing unit 218 executes the program of instructions residing in a programmable storage device (not shown), the expected coefficients of movement entered into the program of instructions, identification of the calling network, RSSI,
It shows that digital signals are processed based on light and temperature. As shown in block 318, the central processing unit 218 determines whether the processed digital signal meets predetermined criteria for an audible alert. If so, block 320 indicates that the central processing unit 218 sends a control signal to an audible alert generator 234 connected to the speaker 238 to generate an audible alert signal. It is believed that the volume of the audible alert signal can be determined based on the decision to process the program of instructions at block 316. If the optimal alert signal is not an audible alert signal, as indicated by decision block 318, central processing unit 218 determines whether the haptic alert signal is best, as indicated by decision block 322. If that is the case, the central processing unit 218 will be able to
2 to generate a haptic alert signal as shown in block 324. Instead, the central processing unit 2
18 sends a control signal to the display device 228 to block 3
As shown at 26, a visible warning signal can be generated. Thus, once the alert signal is generated, central processor 218 processes the call or message, as indicated by block 328.

If the perceived noise is found to have an immovable spectral distribution, the ringer beep of the audible alert generator 234 can be adjusted to be optimal for detection by frequency equalization of the ringing beep. I can do it. Using frequency equalization, set the alert signal to sound at a frequency that maximizes the signal-to-noise ratio. In this case, a ringer tone that covers a better part of the audible spectrum is preferred. If the noise is found to be intermittent, it can be timed to emit a warning beep during periods of low ambient noise. The wireless device 200 is in a confined container (ie, the user is watching a movie in a dark room) using additional acoustic / echo analysis taken from the generated signal sound as shown at block 306. May be supported or denied. Block 30
The characterization of the environment shown at 6-312 can be performed periodically during the standby mode, or continuously as well as immediately prior to the alerting event. The characterization of a periodic environment can be based on all inputs observed over a period of time, or on certain inputs during a shorter observation period to reduce power consumption. As an option, prior to an incoming call, wireless device 200 may cause the user to display an automatically determined type of environment by using a menu on display 228. The user can then deselect the preferred alert signal.

The user can notify the wireless device that a bad alert has been selected. This increases the probability of its future success, ie, self-learning. In this user mode of operation, the first embodiment 100 (see FIG. 1c)
As described in, the user can "train" the wireless device 200 to respond according to the user's preferences. The display device 228 can display a menu of information that can be selected. The menu selected for training the definition of an optimal alert sequence may include default set and reset features so that after answering a series of questions using the select key, You can set a default value. Within this menu, the user can define different alerts for different types of environments, such as "quiet", "noisy", "daytime", "night", "belt", "wallet", and the like. Thus, in a typical noisy environment where it is common, such as in a factory, the wireless device can be calibrated to increase the probability of detecting an optimal warning signal. Alternatively, the definition of the standard default optimal alert sequence can be stored in memory 216. The menu may include an option to change the final alert response based on the environment of the wireless device. The user selects a preferred response and saves the response so that whenever the wireless device is in the same environment that generated this last alert response, future decisions will include the user's input. I can do it. An advantage is, but not limited to, providing a wireless device that more effectively determines an optimal alert signal in high or low ambient noise environments, where the alert signal and volume are adapted to the environment. I have. Another advantage of this wireless device is that it uses a warning signal that is activated in an audible frequency band with less ambient noise. Because the wireless device automatically adapts its characteristics to the environment, it maximizes the likelihood that it will be detected in various environments and reduces the probability of missing a call, message or reminder. In environments with low ambient noise, disturbances caused by warning signals are minimized, which is important in public environments and quiet public places, such as museums, libraries or churches.
