Preferred embodiments of the present invention will be described below in more detail, with reference to the accompanying drawings, in which:
While the specification concludes with claims defining features of the invention that are regarded as novel, it is believed that the invention will be better understood from a consideration of the description in conjunction with the drawings. As required, detailed embodiments of the present invention are disclosed herein; however, it is to be understood that the disclosed embodiments are merely exemplary of the invention, which can be embodied in various forms. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present invention in virtually any appropriately detailed structure. Further, the terms and phrases used herein are not intended to be limiting but rather to provide an understandable description of the invention.
The present invention relates to a method for detecting circumstances in which a user of a mobile station would benefit from receiving high quality multimedia information as opposed to multimedia information transmitted in a standard manner and, responsive to the detected circumstances, automatically configuring at least one parameter of a communication signal which communicates the multimedia information to the mobile station. For example, multimedia information to be transmitted to the mobile station can be encoded with a higher bit rate or resolution in comparison to standard encoding parameters. The multimedia information also can be encoded with a low loss encoding scheme. Increasing the quality of multimedia information in this manner facilitates user processing of the information in comparison to processing of multimedia information presented in a standard manner. For instance, when a mobile station is being used in a moving vehicle or otherwise noisy environment, increasing the quality of audio information can reduce the amount of concentration required of the user to process such information.
The communications network 110 can include the Internet, the World Wide Web, a wide area network (WAN), a local area network (LAN), a cellular communications network, a dispatch communications network, a public switched telephone network (PSTN), or any other communications network over which communications can be propagated. In that regard, the communications network 110 can include wired and/or wireless communication links.
The system 100 also can include a communication device 115. The communication device 115 can be a mobile station or a non-mobile communication device. For example, the communication device 115 can be a computer, a PDA, a telephone, a mobile telephone, such as a cellular telephone or a PTT telephone, a game console or any other device that may be used to communicate with the mobile station 105 via the communications network 110.
In operation, the mobile station 105 can detect conditions which indicate that it would be desirable to receive multimedia information 120 (e.g. audio/video, exclusively audio or exclusively video) from the communication device 115 at a quality that is higher than a standard quality level. For example, the mobile station 105 can detect that it is being used in a noisy environment by measuring an amount of background noise. The mobile station 105 also can detect whether it is being used in a vehicle. For example, the mobile station 105 can detect the presence of a vehicle Bluetooth adapter or Bluetooth beacon which is paired with the mobile station 105. In another aspect of the invention, the mobile station 105 can detect activation of a noise cancellation system within a vehicle.
The mobile station 105 also can detect whether it is being used in a vehicle, worn by a person who is performing a physical activity, for instance skiing, skateboarding, skydiving, etc., or by detecting movement at a rate of speed equal to or greater than a threshold value. For example, the mobile station 105 can utilize one or more global positioning satellite (GPS) services, or any other suitable positioning services, to detect such movement. In another arrangement, an accelerometer can be used to detect acceleration, which indicates movement. The mobile station 105 also can detect any other parameters indicative of the mobile station 105 being used within a vehicle.
In response to detecting a circumstance that indicates it would be desirable to receive the multimedia information 120 at a quality that is higher than a standard quality level, the mobile station 105 can communicate a quality indicator 125 to the communication device 115 and/or another node of the communications network 110, for instance network infrastructure, such as a server 130, a basestation, or a basestation controller. The quality indicator 125 can be a message, a flag that is set in a header or footer of data packet or frame, or any other indication suitable for indicating that high quality multimedia information is requested. Moreover, the configuration of the mobile station 105 can be optimized for the detected circumstance. For example, the mobile station 105 can be configured to optimize its presentation of high quality multimedia information.
In response to receiving the quality indicator 125, the communication device 115 can increase the quality of communication signals it communicates to the mobile station 105. For example, the communication device 115 can encode audio information with a sampling rate that is higher than a standard sampling rate used by the communication device 115, increase the number of bits representing each audio sample, change a vocoder encoding scheme to a scheme that is less lossy than a standard vocoder scheme, or implement any other processes suitable for improving quality of the multimedia information 120. In another arrangement, the mobile station 105 also can send equalization settings to be used by the communication device's vocoder when encoding the multimedia information 120. The equalization settings can be settings which are optimized for the user of the mobile station 105, for instance based on user preferences.
Changing the encoding scheme used to encode the multimedia information 120 can increase the amount of data communicated between the communication device 115 and the mobile station 105. To accommodate the increase, the bandwidth allocated for an uplink 135 from the communication device 115 and for a downlink 140 to the mobile station 105 can be increased. For example, the amount of bandwidth can be doubled. Allocation of the bandwidth can be controlled by the network infrastructure, for instance a server 130, a basestation, a basestation controller, or by any other suitable component of the communications network 110.
In another arrangement, communication signals can be buffered or otherwise altered by the server 130 prior to being transmitted to the mobile station 105 or the communication device 115. For example, the server 130 may process the communications signals by applying translation, text-to-speech services, or other processes that may affect the quality of such signals. In such an arrangement, the amount of storage space allocated by the server can be increased and/or higher quality processing schemes can be applied to the communication signals to increase the quality of such signals.
In yet another arrangement, certain features of the mobile station 105 can be disabled to accommodate the increased amount of data, prioritize tasks for presentation of high quality multimedia information 120, preserve battery life while presenting the high quality multimedia information 120, or accomplish any other suitable task. For instance, mobile station features that are not likely to be useful to a user while driving can be disabled. Examples of such features include, but are not limited to, web browsing and instant messaging.
In one arrangement, if a plurality of input transducers (e.g. microphones) are available for detecting acoustic signals communicated by a user of the communication device 115, an input transducer that receives the acoustic signals with the highest quality can be selected to receive the acoustic signals. Similarly, if there are a plurality of output transducers (e.g. loudspeakers) available to the mobile station 105 for generating acoustic signals from the multimedia information 120, one or more of the output transducers that generate acoustic signals with the highest quality can be selected to generate the acoustic signals. For example, the mobile station 105 can connect to another multimedia presentation system, such as an audio system within a vehicle, via a Bluetooth communication link and communicate audio signals contained in the multimedia information 120 to the audio system. Further, if the vehicle includes a noise cancellation system, the mobile station 105 can selectively activate the noise cancellation system to cancel background noise during call sessions.
In yet another arrangement, if the mobile station 105 and/or the communication device 115 are simultaneously connected to a plurality of communications networks 110, 145, the communications network 145 that communicates the multimedia information 120 with the highest level of quality can be selected to propagate the multimedia information 120 from the communication device 115 to the mobile station 105. In addition, the data compression/encryption that is used to compress and/or encrypt the multimedia information 120 for communication over the communications network 145 can be selected to provide a high level of quality. Still, a myriad of other settings can be changed on the mobile station 105, the communication device 115, the communications network 110, and/or the communications network 145 in response to the quality indicator 125. Accordingly, the invention is not limited in this regard.
A service for providing high quality multimedia information to the mobile station 105 can be provided for a monthly charge. For instance, it can be determined whether an account associated with the mobile station 105 subscribes to the high quality multimedia service. If so, monthly charges can be applied to the account. In another arrangement, the high quality multimedia service can be provided on an as needed basis, in which case charges can be applied when the high quality multimedia service is used. For example, in response to automatically configuring a parameter to provide the multimedia information 120 at a quality that is higher than a standard quality, charges can be applied to an account associated with the mobile station 105. In yet another arrangement, charges can be applied to prepaid call units that are managed by the mobile station 105 when high quality multimedia services are used.
The mobile station 105 also can include a communications adapter 210 that is used by the mobile station 105 to communicate with the communications network. The communications adapter 210 can include, for example, a transceiver that communicates data via IEEE 802 wireless communications, WPA, WPA2, GSM, TDMA, CDMA, WCDMA, direct wireless communication, TCP/IP, or any other suitable form of mobile communications.
A second communications adapter 215 also can be provided support communications between the communication device 120 and other devices, for example vehicle accessories. The second communications adapter 215 also can be used to detect when the mobile station 105 is proximate to such devices. For example, the communications adapter 215 can include a transceiver that communicates short range signals in accordance Bluetooth and/or detects Bluetooth beacons. In one arrangement, the second communications adapter 215 can be integrated with the communications adapter 210.
The mobile station 105 also can include an audio processor 220 connected to an input audio transducer 225 (e.g. microphone) and an output audio transducer 230 (e.g. loudspeaker). The audio processor 220 can comprise a vocoder for encoding and decoding speech signals. Vocoders are known to the skilled artisan. The audio processor 220 can be integrated with the controller 205, or provided as a separate component that is communicatively linked to the controller 205. The audio processor 220 can comprise a CPU, a DSP, an ASIC, a PLD, a plurality of discrete components that cooperate to process audio data, and/or any other suitable audio processing device.
The audio processor 220 can receive input audio signals from a user via the input audio transducer 225, and propagate output audio signals to the user via the output audio transducer 230. In one arrangement, the audio processor also can propagate output audio signals to the user via the second communications adapter 215. For example, the audio processor 220 can forwarded decoded audio signals to the communications adapter 215, which can communicate the audio signals to an audio system within a vehicle that is suitably configured to receive such communications.
The mobile station 105 also can include a video processor 235 connected to a display 240. The video/image processor 235 can be integrated with the controller 205, or provided as a separate component that is communicatively linked to the controller 205. The video processor 235 can comprise a CPU, a DSP, an ASIC, a PLD, a plurality of discrete components that cooperate to process video data, and/or any other suitable audio processing device. The video processor 235 can display images to the user via the display 240.
A motion sensor 245 can be communicatively linked to the controller 205. The motion sensor 245 can be, for example, a GPS receiver or an accelerometer. A GPS receiver can receive GPS signals from one or more GPS systems to track location and movement of the mobile station 105. An accelerometer can detect acceleration of the mobile station 105, which indicates movement. The motion sensor 245 can communicate data corresponding to the mobile station's location and movement to the controller 205.
The mobile station 105 also can include a datastore 255. The datastore 255 can include a magnetic storage medium, an electronic storage medium, an optical storage medium, a magneto-optical storage medium, or any other storage medium suitable for storing digital information. In one arrangement, the datastore 255 can be integrated into the controller 205.
A circumstance detection application 260 can be contained on the datastore 255 to execute processes described herein. In particular, the circumstance detection application 260 can be executed by the controller 205 to detect whether a user of a mobile station 105 would benefit from receiving high quality communication signals over the communications adapter 210 as opposed to communication signals transmitted in a standard manner. For example, the controller 205 can receive a detection signal 250 from the communications adapter 215 which indicates whether the mobile station 105 is communicatively linked to a vehicle via the communications adapter 215. In one aspect of the invention, the detection signal 250 can include a vehicle identifier.
In another arrangement, the controller 205 can receive a detection signal 250′ from the audio processor 220 which indicates whether the mobile station 105 is communicatively linked to a vehicle via the communications adapter 215. For example, the audio processor 220 can monitor audio signals received from the input audio transducer 225 and process the audio signals to determine whether the signals indicate that the mobile station 105 is activated in a noisy environment. For instance, algorithms can be applied to process the data in a manner that identifies a level of background noise. In another arrangement, the audio processor 220 can compare a spectral content of received audio signals with the known spectral content of background noise.
In yet another aspect of the inventive arrangements, the controller 205 can receive a detection signal 250″ from the motion sensor 245. In an arrangement in which the motion sensor 245 is a GPS receiver, the detection signal 250″ can indicate the position of the mobile station 105 and the controller 205 can process a plurality of such signals at known intervals to determine whether the mobile station 105 is moving, and at what speed. In another arrangement, the motion sensor 245 can determine whether the mobile station 105 is moving and detect the speed, then forward such data to the controller 205 in the detection signal 250″. In an arrangement in which the motion sensor 245 is an accelerometer, the motion sensor 245 can detect an acceleration greater than a threshold value and forward a corresponding acceleration indicator in the detection signal 250″.
If it is determined that the user of the mobile station 105 would benefit from receiving high quality communication signals over the communications adapter 210, the controller 205 can communicate the quality indicator 125 via the communications adapter 210. The quality indicator 125 can be communicated to the communication device with which the mobile station 105 is establishing a call session, network infrastructure, and/or any other network node suitable for causing high quality multimedia signals to be sent to the mobile station 105.
In one arrangement, the circumstance detection application 260 can present a user selectable option via the display 240 which allows the user to selectively enable or disable implementation of high quality multimedia mode by entering an input into a keypad 270 or a button. For example, charges may be applied to an account associated with the mobile station 105 for use of additional bandwidth that may be required to receive the high quality multimedia information, and the user may not wish to pay such charges. Further, the circumstance detection application 260 can present an icon or other indicator on the display 240 when the mobile station 105 is requesting high quality multimedia information, or when such a call session is established, to alert the user that additional bandwidth may be used.
The communication device 115 also can include a communications adapter 310 that is used by the communication device 115 to communicate with the communications network. The communications adapter 310 can include, for example, a transceiver that communicates data via IEEE 802 wireless communications, WPA, WPA2, GSM, TDMA, CDMA, WCDMA, direct wireless communication, TCP/IP, or any other suitable form of mobile communications.
The communication device 115 also can include an audio processor 315 connected to one or more input audio transducers 320, 325 and one or more output audio transducers 330, 335. The audio processor 315 can comprise a vocoder for encoding and decoding speech signals. Vocoders are known to the skilled artisan. The audio processor 315 can be integrated with the controller 305, or provided as a separate component that is communicatively linked to the controller 305. The audio processor 315 can comprise a CPU, a DSP, an ASIC, a PLD, a plurality of discrete components that cooperate to process audio data, and/or any other suitable audio processing device.
In one arrangement, a second audio processor (not shown) can be provided and communicatively linked to the audio processor 315 and/or the controller 305. For example, the second audio processor can be integrated with a communication accessory, such as a headset, and wirelessly linked to the controller 305. In such an arrangement, the input audio transducer 325 and the output audio transducer 335 can be connected to the second audio processor.
The communication device 115 also can include an image sensor 340 that detects images. The image sensor 340 can include a charge-coupled device (CCD), a complementary metal oxide semiconductor (CMOS) image sensor, or any other image sensor suitable for capturing images. Such sensors are known to the skilled artisan. An image processor 345 can be operatively connected to the image sensor 340 and process the images detected by the image sensor 340 and generate image data 350 comprising still images or video information. Image processors also are known to those skilled in the art.
The communication device 115 also can include a datastore 355. The datastore 355 can include a magnetic storage medium, an electronic storage medium, an optical storage medium, a magneto-optical storage medium, or any other storage medium suitable for storing digital information. In one arrangement, the datastore 355 can be integrated into the controller 305.
A multimedia encoding application 360 can be contained on the datastore 355 and executed by the audio processor 315, the image processor 345 and/or the controller 305 to perform processes described herein. The multimedia encoding application 360 can be executed to select the input audio transducer 320 or the input audio transducer 325 from which to receive input audio signals. For example, the input audio transducer 320, 325 known to generate the highest quality audio signals can be selected for receiving audio signals in response to the quality indicator being communicated by the mobile station 105.
In addition, the multimedia encoding application 360 can be executed when encrypting audio signals received from the input audio transducer 320 and/or the input audio transducer 325, and/or encrypting image data 350 received from the image sensor 340. For example, the multimedia encoding application 360 can select a vocoder algorithm that is used by the audio processor 315 to compress audio signals 365 prior to the audio signals 365 being communicated to the controller 305. The multimedia encoding application 360 also can select an encryption algorithm that is used by the controller 305 to encrypt the audio signals 365, along with any other multimedia signals that may be communicated, such as the video signals 350, into the multimedia information 120. The controller 305 then can forward the multimedia information 120 to the communications adapter 310, which can communicate the multimedia information 120 to the mobile station.
In one arrangement, the multimedia encoding application 360 also can communicate with a user interface 370 on the communications device 115 and present a user of the communication device an option to accept or reject the request to provide high quality multimedia information. For example, charges may apply for use of additional bandwidth that may be required to transmit the high quality multimedia information 120, and the user may not wish to pay such charges. Further, the multimedia encoding application 360 can present an icon or other indicator on the user interface 370 when a call requesting high quality multimedia information is being requested, or when such a call session is established.
Referring again to step 510, monitoring for a quality indicator can continue and the multimedia settings can be changed in response to the quality indicator being changed during a call session, the quality indicator no longer being received during a call session, or the quality indicator being received during a call session in which it was not previously received. For example, in response to a user of the mobile station entering his car while participating in a call session, the mobile station can transmit the quality indicator to the communication device and/or the network infrastructure. In response to the quality indicator, parameters for the communication signal communicating the multimedia information can be changed to convey the multimedia information at a high quality. Similarly, if the user exits his car while still participating in the call session, the communication device and/or the network infrastructure can detect that the quality indicator is no longer being received, or detect a change in the quality indicator, and thus change parameters for the communication signal to standard multimedia settings. Nonetheless, in one aspect of the invention use of high quality multimedia settings can be established by a user preference. In such an arrangement, the high quality multimedia settings can be maintained whether or not the user enters or leaves his vehicle.
Continuing to step 640, the communication device 115 can communicate to the network node 605 a voice request for the mobile station 105. At step 645, the network node 605 can request the state of the mobile station 105, for example, whether the mobile station 105 is activated in a vehicle. In response, at step 650 the mobile station 105 can report its state to the network node 605. For example, the mobile station 105 can respond with a data packet in which the quality indicator flag is set, thereby indicating that it is preferred for audio communicated to the mobile station 105 to be transmitted using high quality multimedia settings. At step 655, the network node 605 can grant a high quality uplink channel to the communication device 115. At step 660 the communication device 115 can transmit high quality multimedia information to the network node 605, which at step 665 can transmit the high quality multimedia information to the mobile station 105.
