This invention relates to wireless communication systems, and more specifically, to the playback of text-based messages via an audio system.
The convergence of the IP-based services and cellular communications services has opened the door for providing services that heretofore were not available to the cellular user who seeks access to IP-based networks, as well as for IP users seeking access to services of the cellular networks. Wireless devices such as portable computers and smartphones can now access services on wired/wireless networks using IP technology. Such advances have served as a catalyst for a mobile society where workers can commute greater distances while maintaining connectivity to businesses or homes. For example, users can be seen talking on cell phones and operating computers as they travel from location to location. These activities, while troublesome, are yet to be regulated in any significant way.
In today's world of electronics, there can be many potential distractions to drivers while traveling. For example, drivers read email, response to test messaging and/or attempt to listen to voicemail while driving. Conventional applications that attempted to address this growing problem employed FM modulators with small attached microphones to play voicemail, for example. However, there needs to be more hands-free, and hence, safer, mechanisms available for listening to email and other information while in a vehicle, whether the vehicle is moving or not.
The following presents a simplified summary in order to provide a basic understanding of some aspects of the disclosed architecture. This summary is not an extensive overview, and it is not intended to identify key/critical elements or to delineate the scope thereof. Its sole purpose is to present some concepts in a simplified form as a prelude to the more detailed description that is presented later.
The disclosed innovative architecture allows a user to receive personal messages (e.g., text-based) such as email and voicemail over a vehicle media system (e.g., radio). In one example, the vehicle user can listen to email and/or voicemail, and browse through such messages while the messages are being played over a car audio system.
In one embodiment, the user employs a cell phone that registers over the cellular network to an IMS (IP multimedia subsystem) to obtain an associated IP address. The personal messages are then converted into audio signals using a remote text-to-voice (TTV) converter and transmitted to the phone. The phone then transmits the audio signals to the vehicle media system for playback using an unlicensed wireless technology (e.g., Bluetooth, Wi-Fi, etc.).
In another embodiment, the user cell phone registers over the cellular network to the IMS entity to obtain an associated IP address. The personal messages are then converted into audio signals using the remote TTV converter and transmitted to the vehicle media system for playback based on the IP address associated with the cell phone. The user can then interact using the cell phone to browse other messages for download and playback.
In yet another embodiment, the user cell phone registers over the cellular network to the IMS entity to obtain an associated IP address. The personal messages are then input into the remote TTV converter and streamed therefrom over a direct bearer channel to the vehicle media system for playback based on the IP address associated with the cell phone. The user can then interact using the cell phone to browse other messages for download and playback.
In still another embodiment, the user cell phone registers over the cellular network to obtain an associated IP address. The requested text-based messages are then converted remotely and sent to a satellite system for further communication over a dedicated satellite channel to the vehicle (cell phone) associated with the IP address.
In another embodiment, the email and voicemail can be converted to an audio file format (e.g., MP3), sent to the cell phone, and therefrom, via an unlicensed wireless technology (e.g., short range communications) to a radio receiver that is already MP3-ready, for example.
To the accomplishment of the foregoing and related ends, certain illustrative aspects of the disclosed architecture are described herein in connection with the following description and the annexed drawings. These aspects are indicative, however, of but a few of the various ways in which the principles disclosed herein can be employed and is intended to include all such aspects and their equivalents. Other advantages and novel features will become apparent from the following detailed description when considered in conjunction with the drawings.
As required, detailed novel embodiments are disclosed herein. It must be understood that the disclosed embodiments are merely exemplary and may be embodied in various and alternative forms, and combinations thereof. As used herein, the word “exemplary” is used expansively to refer to embodiments that serve as an illustration, specimen, model or pattern. The figures are not necessarily to scale and some features may be exaggerated or minimized to show details of particular components. In other instances, well-known components, systems, materials or methods have not been described in detail in order to avoid obscuring the invention. 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 invention.
Suitable wireless and radio frequency (RF) data transmission systems in which the disclosed invention can be implemented include, but are not limited to, networks utilizing time division multiple access (TDMA), frequency division multiple access (FDMA), wideband code division multiple access (WCDMA), orthogonal frequency division multiplexing (OFDM), wireless fidelity (Wi-Fi), and various other 2.5 and 3G (third generation) and above wireless communications systems. Examples of other suitable enabling bearers include universal mobile telecommunications system (UMTS), enhanced data rates for global evolution (EDGE), high speed downlink/uplink packet access (HSDPA/HSUPA), voice over Internet protocol (VoIP), and similar communications protocols.
Reference is now made to the drawings, wherein like reference numerals are used to refer to like elements throughout.
Referring initially to the drawings,
In operation, a user can receive personal messages to be played by the vehicle media system 102. For example, an email message can be initially delivered to the messaging system 110 as a text message, converted to into an audio format (e.g., MP3), transmitted to the communications component 108 of the vehicle 104, and then played by the media system 102. Alternatively, or in combination therewith, the messaging system 110 can include a text-to-voice (TTV) converter subsystem (not shown) for converting text messages (e.g., email, SMS, etc.) into voice for playback on the media system 102.
In one implementation, the messaging system 110 begins streaming the voice file to the communications component 108 as the voice file is being converted from text by the TTV converter. Alternatively, the messaging system 110 receives a trigger signal (e.g., from a cellular system) that causes the TTV subsystem to begin converting the stored messages from the user account and then sending the converted audio (or voice) files to the communications component 108 ultimately for playback by the vehicle media system 112.
Note that as used herein, the term “vehicle” includes any transportation mechanism such as an automobile, truck, vessel, water craft, aircraft, and motorized or un-motorized transport system, for example.
In another implementation, the user account can include stored voicemail messages which may already be in a suitable audio format (e.g., MP3, WAV, etc.) for transmission to the communications component 108. If not, the voicemail messages can be routed through the TTV converter for conversion into a suitable audio format for playback by the vehicle media system 112.
As illustrated, the messaging system 110 communicates the person message directly to the vehicle communications component 108. In other words, the personal messages can be transmitted via RF signals using a satellite system (not shown). Alternatively, or in combination therewith, the messaging system 110 can be an IP-based cellular communications system for communicating a converted message to the communications component 108. For example, the communications component 108 can register with an IP multimedia subsystem (IMS) entity of a cellular network to receive the personal messages as IP-based packets. Given the nature of data packets and associated communications medium, it is also possible to encrypt the personal messages as a means of providing security against unauthorized access of the personal messages during the communications process.
It is also within contemplation of the subject architecture that the vehicle media system 112 can receive and output multimedia content via a display such that the vehicle user can view the personal message separately or in combination with hearing the audio playback.
The phone user does not need to receive the audio output while the vehicle 104 is moving. Moreover, the phone 202 does not need to be inside the vehicle 104. All that is required is that the phone 202 be within the radio range of the communications component 108 based on the particular wireless technology (e.g., Bluetooth) employed for communications between the phone 202 and the communications component 108. Thus, the user can listen to the message(s) while parked and standing outside the vehicle 104. Additionally, the connection between the phone 202 and the communications component 108 can be via a cable or wire rather than wireless, or used in combination with the wireless connection.
The system 300 includes a home subscriber server (HSS) 302 that can be employed to store and serve user (or subscriber) profiles (e.g., preferences, accounts, etc.), perform authentication and authorization functions, and physical location information about the user. The HSS 302 provides the interface between the IMS entity 206 and a text and voice component 304. The HSS 302 stores the text and/or voice data received from the component 304, and serves the data into the IMS entity 206 for conversion, where desired. In support thereof, if text data is served up from the HSS 302 for communication to the phone 202, the text data is passed to the TTV converter 208 for conversion, and then back to the IMS 206 for IP communication to the phone 202. As previously indicated, this can be communicated to the phone 202 wirelessly via the cellular network and/or a satellite system. Similar, a voice file from the component 304 that is stored on the HSS 302 can be accessed by the IMS 206 or pushed to the IMS 206 from the HSS 302 for conversion (if needed) and communications to the phone 202.
The system 300 can also include an email component 306 (e.g., an email server) that processes email, but which can also route email to the TTV converter 208 for conversion and transmission indirectly through the IMS 206 to the phone 202, and/or directly (via transfer pathway 308) from the TTV component 208 to the phone 202 (bypassing the IMS 206). In other words, text can be sent to the converter 208 for conversion and communication to the phone 202 as streaming audio over a direct bearer channel (e.g., the pathway 308).
In operation, text, voicemail, email, or other types of personal messages can be received from the text/voice component 304 and/or the email component 306 into the messaging system 110. Based on IMS registration, the raw text, voice, email, or other messages can be routed to the registered phone 202, and processed internally into audio data for output by the vehicle media system 112. Use of the remote converter 208 or the local converter 502 can be selectable based on the system 500 capabilities. For example, it is to be appreciated that local conversion can be a processor-intensive operation such that it may be preferred to convert the messages remotely first, and then simply forward the converted files from the phone 202 to the vehicle media system 112 for playback.
It should be understood that the subject architecture is not limited to cell phones, but also applies to portable devices that have mobile capabilities, such as portable computers, for example. In other words, the vehicle user can register a portable computer to the IMS entity 206 and TTV converter 208, and have email converted, downloaded, and wirelessly transmitted from the portable computer to the communications component 108 for playback by the vehicle media system 112.
At 600, a vehicle-based media system is received for playing content in a vehicle via an audio subsystem. At 602, registration is to an IP system via a cellular network for an associated IP address. At 604, the cellular network is accessed to download personal messages for playback based on the IP address. At 606, the audio signals associated with the personal messages are played via the media system.
As used in this application, the terms “component” and “system” are intended to refer to hardware, a combination of hardware and software, software, or software in execution. For example, a component can be, but is not limited to being, a process running on a processor, a processor, a hard disk drive, multiple storage drives (of optical and/or magnetic storage medium), an object, an executable, a thread of execution, a program, and/or a computer or mobile terminal (cell phone).
Generally, applications (e.g., program modules) can include routines, programs, components, data structures, etc., that perform particular tasks or implement particular abstract data types. Moreover, those skilled in the art will appreciate that the inventive methods can be practiced with other system configurations, including single-processor or multiprocessor systems, minicomputers, mainframe computers, as well as personal computers, hand-held computing devices, microprocessor-based or programmable consumer electronics, and the like, each of which can be operatively coupled to one or more associated devices.
The handset 1000 (e.g., a cell phone) can typically include a variety of computer-readable media. Computer-readable media can be any available media accessed by the handset systems and includes volatile and non-volatile media, removable and non-removable media. By way of example, and not limitation, computer-readable media can comprise device storage media and communication media. Storage media includes volatile and/or non-volatile, removable and/or non-removable media implemented in any method or technology for the storage of information such as computer-readable instructions, data structures, program modules or other data. Storage media can include, but is not limited to, RAM, ROM, EEPROM, flash memory or other memory technology, CD-ROM, digital video disc (DVD) or other optical disk storage, magnetic tape, magnetic disk storage or other magnetic storage devices, or any other medium which can be used to store the desired information and which can be accessed by the handset systems.
The handset 1000 includes a processor 1002 for controlling and processing onboard operations and functions. A memory 1004 interfaces to the processor 1002 for the storage of data and one or more applications 1006 (e.g., a video player software, user feedback component software, etc.). The applications 1006 can also include a user interface (UI) application 1008 that operates with a client 1010 (e.g., operating system) to facilitate user interaction with handset functionality and data, for example, answering/initiating calls, entering/deleting data, configuring settings, address book manipulation, multimode interaction, etc. The applications 1006 can include other applications 1012 that came installed with the handset 1006 and/or can be installed as add-ons or plug-ins to the client 1010 and/or UI 1008, for example, or for other purposes (e.g., processor, firmware, etc.).
The other applications 1012 can include voice recognition of predetermined voice commands that facilitate user control, call voice processing, voice recording, messaging, e-mail processing, video processing, image processing, music play, as well as subsystems or components described infra. Some of the applications 1006 can be stored in the memory 1004 and/or in a firmware 1014, and executed by the processor 1002 from either or both the memory 1004 or/and the firmware 1014. The firmware 1014 can also store code for execution in power-up initialization and control during normal operation of the handset 1000.
A communications component 1016 can interface to the processor 1002 to facilitate wired/wireless communications with external systems, for example, cellular networks, VoIP (voice-over-IP) networks, local wireless networks or personal wireless networks such as Wi-Fi, Wi-Max, and so on. Here, the communications component 1016 can also include a multimode communications subsystem for providing cellular communications via different cellular technologies. For example, a first cellular transceiver 1018 (e.g., GSM) can be one mode and an Nth transceiver 1020 can provide cellular communications via an Nth cellular network (e.g., UMTS), where N is a positive integer. The communications component 1016 can also include a transceiver 1022 for unlicensed communications (e.g., Wi-Fi, Wi-Max, Bluetooth, etc.) for corresponding communications. The communications component 1016 can also facilitate communications reception from terrestrial radio networks (e.g., broadcast), digital satellite radio networks, and Internet-based radio services networks.
The handset 1000 can process IP data traffic via the communications component 1016 to accommodate IP traffic from an IP network such as, for example, the Internet, a corporate intranet, a home broadband network, a personal area network, etc., via an ISP or broadband cable provider. Thus, VoIP traffic can be utilized by the handset 1000 and IP-based multimedia content can be received in an encoded and/or decoded format.
The handset 1000 includes a display 1024 for displaying multimedia that include text, images, video, telephony functions (e.g., a Caller ID function), setup functions, menus, etc. The display 1024 can also accommodate the presentation of multimedia content (e.g., music metadata, messages, wallpaper, graphics, etc.).
An input/output (I/O) interface 1026 can be provided for serial/parallel I/O of data and/or signals (e.g., USB, and/or IEEE 1394) via a hardwire connection, and other I/O devices (e.g., a keyboard, keypad, mouse, interface tether, stylus pen, touch screen, etc.). The I/O interface 1026 can be utilized for updating and/or troubleshooting the handset 1000, for example.
Audio capabilities can be provided via an audio I/O component 1028, which can include a speaker for the output of audio signals related to, for example, indication that the user pressed the proper key or key combination to initiate the user feedback signal, call signals, music, etc. The audio I/O component 1028 also facilitates the input of audio signals via a microphone to record data and/or telephony voice data, and for inputting voice signals for telephone conversations.
The handset 1000 can include a slot interface 1030 for accommodating a subscriber identity system 1032 that can accommodate a SIM or universal SIM (USIM), and interfacing the subscriber identity system 1032 with the processor 1002. However, it is to be appreciated that the subscriber identity system 1032 can be manufactured into the handset 1000, and updated by downloading data and software thereinto.
An image capture and processing system 1034 (e.g., a camera) can be provided for decoding encoded image content. Additionally, as indicated, photos can be obtained via an associated image capture subsystem of the image system 1034. The handset 1000 can also include a video component 1036 for processing video content received and, for recording and transmitting video content.
Optionally, a geolocation component 1038 (e.g., GPS-global positioning system) facilitates receiving geolocation signals (e.g., from satellites via the communications component 1016) that define the location of the handset 1000. Alternatively, or in combination therewith, the geolocation component 1038 can facilitate triangulation processing for locating the handset 1000.
The handset 1000 also includes a power source 1040 in the form of batteries and/or an AC power subsystem, which power source 1040 can interface to an external power system or charging equipment (not shown) via a power I/O component 1042.
The handset 1000 can also include a TTV converter component 1044 for local conversion of text-based messages (e.g., email) into voice (or audio) files. The voice files can then be communicated via the handset communications component 1016 to the vehicle media system 112 for audio playback.
Wi-Fi networks can operate in the unlicensed 2.4 and 5 GHz radio bands. IEEE 802.11 applies to generally to wireless LANs and provides 1 or 2 Mbps transmission in the 2.4 GHz band using either frequency hopping spread spectrum (FHSS) or direct sequence spread spectrum (DSSS). IEEE 802.11a is an extension to IEEE 802.11 that applies to wireless LANs and provides up to 54 Mbps in the 5 GHz band. IEEE 802.11a uses an orthogonal frequency division multiplexing (OFDM) encoding scheme rather than FHSS or DSSS. IEEE 802.11b (also referred to as 802.11 High Rate DSSS or Wi-Fi) is an extension to 802.11 that applies to wireless LANs and provides 11 Mbps transmission (with a fallback to 5.5, 2 and 1 Mbps) in the 2.4 GHz band. IEEE 802.11g applies to wireless LANs and provides 20+Mbps in the 2.4 GHz band. Products can contain more than one band (e.g., dual band), so the networks can provide real-world performance similar to the basic 10BaseT wire Ethernet networks used in many offices.
The law does not require and it is economically prohibitive to illustrate and teach every possible embodiment of the present claims. Hence, the above-described embodiments are merely exemplary illustrations of implementations set forth for a clear understanding of the principles of the invention. Variations, modifications, and combinations may be made to the above-described embodiments without departing from the scope of the claims. All such variations, modifications, and combinations are included herein by the scope of this disclosure and the following claims. Furthermore, to the extent that the term “includes” is used in either the detailed description or the claims, such term is intended to be inclusive in a manner similar to the term “comprising” as “comprising” is interpreted when employed as a transitional word in a claim.
