CROSS REFERENCE TO RELATED APPLICATION 
       [0001]    This application is a continuation of and claims priority to U.S. application Ser. No. 13/052,081, filed Mar. 20, 2011, now allowed, which is incorporated herein by reference in its entirety, and which is a continuation of U.S. application Ser. No. 11/421,581, filed Jun. 1, 2006, now U.S. Pat. No. 7,912,187, which is incorporated herein by reference in its entirety. 
     
    
     FIELD OF THE INVENTION 
       [0002]    The present invention generally relates to the field of telecommunications. More particularly, the invention relates to a wireless communication system that alters device output modes based on operating parameters. 
       BACKGROUND 
       [0003]    Wireless devices have a number of user controlled parameters that can be adjusted to fit user preferences for a given situation. These parameters can include, for example, ring type, ring volume, and instant messaging presence information, among a plethora of other options. Many devices allow for the creation of profiles that save a number of device settings as a group for each profile, providing a convenient way for quickly changing a number of options at one time. 
         [0004]    Following Federal Communication Commission (FCC) mandates for enhanced  911  service throughout the United States, wireless carriers, in many circumstances now have access to location information for wireless devices connected to their respective networks, and consequently have access to the location information for the users of these devices. 
         [0005]    Location based services are being developed that marry these two concepts so that users are not required to change individual settings or profiles manually, but are instead able to move from place to place with the device changing its parameters based on its location. This can be useful, for example, to set a more conservative ring-tone while the user is in their office of employment, and change the ring-tone to, for example, the opening riff of a rock and roll song once they leave the office. 
         [0006]    Instant messaging services, accessible via a personal computer or other communication devices, enable users of such services to exchange messages or other information with each other in near real-time. A feature of instant messaging services is a personal list, sometimes referred to as a “buddy list,” which includes identification of other users with whom a user frequently communicates via the instant messaging services. The availability status of other users on the personal list, known as an instant messaging presence of a user, includes not only “online” or “offline”, but also user-controlled statuses that may indicate a location of the user, such as “gone to a movie,” “on the phone,” or “eating dinner.” Generally, the user-controlled statuses may be changed in response to an action received by a user interface, such as receipt of a selection of an instant messaging presence via a drop-down menu presented on the display of the communication device. 
         [0007]    Changing settings, profile, and instant messaging information based on user settings and the location of the device can provide convenience and prevent inappropriateness in many cases. However, in some cases this may lead to a user not receiving needed information in a timely manner. For example, a telephone call or voice message for the user may not be delivered to the user while the user is in a meeting where that information would be vital. This can happen, for instance, where the user&#39;s phone, either through a manual setting or a dynamic setting based on location, is placed in a silent mode where the ringer is turned off. A vibrate function can allow the user to know that there is someone calling or that a voice message has been left for the user, but due to the circumstances of the meeting, the user may not be at liberty to take the call or listen to the message. 
         [0008]    In other instances, the user may receive, for example, a short message service (SMS) text message, but be unable to read it due to the activity in which the user is currently engaged or the user&#39;s current situation, such as driving an automobile. 
         [0009]    Therefore, there is a need and desire for a system and method for setting a desired communication format of a wireless device that can affect output modes based on user preferences, and a need for a system and method for affecting output modes based on a location of the device. 
       SUMMARY 
       [0010]    A system according to the present invention for delivering communications to a communication device includes routing logic configured to receive communications in one format, and configured to route the communication to a communication device output or to a format converter based on routing parameters. The system can route text communications to a display output or to a format converter for conversion to a speech format. The system can route speech communications to a speaker output of the communication device or to a format converter for conversion to a text format. 
         [0011]    Routing parameters can include, but are not limited to, a location of the device, an application setting, and a device setting. An application setting and a device setting can be based on a location of the device. An application setting can be an instant messaging application setting. An instant messaging application setting can be an instant messaging presence. 
         [0012]    In some embodiments, the invented system can include a location based services server configured to determine a location of the communication device and to provide the location to the routing logic, where the routing logic is configured to route a communication based on the location. 
         [0013]    In some embodiments, the invented system can also include a messaging server configured to determine an instant messaging presence of a user of the communication device and to provide the instant messaging presence to the routing logic, where the routing logic is configured to route a communications based on the instant messaging presence. 
         [0014]    An invented method according to the present invention can comprise determining a format of a communication intended for the communication device, determining an output mode of the communication device, routing the communication to a particular output of the communication device if the format is a corresponding format, routing the communication to a format converter if the communication is not in a corresponding format, converting the communication to the corresponding format, and sending the converted communication to the output of the communication device. 
         [0015]    The output mode can be set by, for example, a device setting, an application setting, and/or a location of the device. An application setting or a device setting can be based on a location of the device. An application setting can be an instant messaging application setting. An instant messaging application setting can be an instant messaging presence setting. 
         [0016]    A device according to the present invention includes a processor, speaker and display outputs, and computer readable memory. The computer readable memory can include routing logic for directing the processor to route communications in one format to a corresponding device output or to a format converter for conversion to an appropriate format. The decision can be based on one or more routing parameters. 
         [0017]    Routing parameters can include, but are not limited to, a location of the device, an application setting, and a device setting. An application setting and a device setting can be based on a location of the device. An application setting can be an instant messaging application setting. An instant messaging application setting can be an instant messaging presence.

     DETAILED DESCRIPTION 
       [0022]    As required, detailed embodiments of the present invention are disclosed herein. It must be understood that the disclosed embodiments are merely exemplary of the invention that 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 present 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 present invention. 
         [0023]      FIG. 1  is an overall system diagram illustrating the exemplary system in accordance with an embodiment of the present invention. A communication device  100  communicates with a telecommunications network  102  to place and receive voice calls, short message service (SMS) messages, and instant messenger messages through an instant messenger system, in addition to any other communications, via a bi-directional communications link  104 . A location based services (LBS) server  106  can also communicate with the communication device  100  through the telecommunications network  102  via a bi-directional communications link  108 . A messaging server  132  can also be coupled to the telecommunications network  102  via a bi-directional communications link  130 . 
         [0024]    The communication device  100  can be any device capable of receiving and transmitting data. The communication device  100  contains a processing unit  110 , which can be communicatively coupled to other components of the communication device  100  via a system bus  114 . 
         [0025]    The communication device  100  contains a data storage unit  112 , which is discussed in greater detail in  FIG. 2 . Data storage unit  112  can be any type of memory, including but not limited to RAM, EPROM, or EEPROM memory, and can store data in either volatile or non-volatile memory. The processing unit  110  and the data storage unit  112  can communicate via the system bus  114 . Alternatively, the processing unit  110  and the data storage unit  112  can be included on the same microprocessing chip. 
         [0026]    The communication device  100  also includes an I/O interface  116 , which can reside on the same microprocessing chip as the processing unit  110 . However, the I/O interface  116  can also reside on an external unit. The I/O interface  116  can connect the processing unit  110  to a user interface  128 . In the case of a wireless device such as a cellular telephone, the user interface  128  can include a keypad input  118 , a microphone input  120 , and a speaker output  122 . The I/O interface  116  can include an analog-to-digital converter for converting an analog microphone signal to a digital microphone signal for use by the processing unit  110 . The I/O interface  116  can also include a digital-to-analog converter to convert digital information from the processing unit  110  to the speaker output  122 , such as voice data. 
         [0027]    The processing unit  110  transmits and receives digital signals that are to be communicated outside the communication device  100  via communication circuitry  124  connected to an antenna  126 . The antenna  126  communicates signals through airwaves to the telecommunications network  102  via a bi-directional communication link  104  when such a link is established, for example, when a call is placed to or from the communication device  100 . 
         [0028]    In some embodiments, the communication device  100  can include a positioning receiver and antenna (not shown) for receiving positioning signals from positioning satellites to determine a location of the device. 
         [0029]    The telecommunications network  102  receives signals, from the communication device  100  via antenna  126 . The telecommunications network  102  includes various components required to enable communication between two or more communication devices, including wired connections, wireless connections, switches, and other devices for establishing communication in the network. 
         [0030]    The telecommunications network  102  can be communicatively coupled to a location based services (LBS) server  106 , which can be any computer system with a capability to determine the location of a communication device. The telecommunications network  102  can also be coupled to the messaging server  132  via a bi-directional communications link  130 . The messaging server  132  can be any computer system communicating with the telecommunications network to provide messaging capabilities to communication devices on the telecommunications network  102 , including a server of a wireless service provider. The telecommunications network can additionally be connected to a format conversion server  134  configured to convert a communication from a first format to a second format and/or from a second format to a first format. 
         [0031]    The LBS server  106  can be a server capable of determining the location of the communication device  100 . The LBS server  106  communicates location information to the telecommunications network  102  via a bi-directional communications link  108 . The location information can subsequently be transmitted to the communication device  100  via the bi-directional communications link  104 . The messaging server  132  can be used for providing messaging capabilities to the communication device  100  through an interaction with the telecommunications network  102 , including but not limited to, an instant messaging client or server for a wireless services carrier. The messaging server  132  communicates information, such as instant messaging presence or other information pertaining to a user profile, to the telecommunications network  102  via bi-directional communications link  130 . 
         [0032]    Location of the communication device  100  can be determined in a number of ways. The location of the device can be determined using triangulation techniques. Triangulation methods comprise measuring signal characteristics to determine a location of the device. Time of arrival of signals from network base stations to the device can be used as well as time or arrival of signals from the device to network base stations. In addition, other parameters of the signal can be used, including, but not limited to, signal strength, signal phase, and which of a plurality of directional antennas of a base station is receiving the strongest signal from the device. Triangulation techniques are also employed in global positioning system (GPS) based location techniques. In the case of GPS, signal parameters from a plurality of orbiting satellites are measured to determine a location of the device. 
         [0033]    Two standards for measuring mobile device location have emerged in the United States in response to the FCC mandate for location information on mobile devices to deliver enhanced  911  services. These are uplink difference time of arrival (U-TDOA) and assisted GPS (A-GPS). The global services mobile (GSM) wireless carriers are implementing U-TDOA solutions, while CDMA and providers are using A-GPS. The present invention can be implemented in these and other mobile device location determining schemes. 
         [0034]    In addition to the robust techniques listed above, simpler techniques can be used to determine a relative location between the mobile device and a person, place, or object. For example, a short-range radio beacon, such as a Bluetooth radio can be used to communicate with Bluetooth capable devices. By merely establishing communication between the two Bluetooth radios, the mobile device can be made aware that it is close enough to the external Bluetooth radio to be within its communication radius. Another example of this location technique is the use of a car cradle, home charger, or any device that physically interfaces with the mobile communication device  100 . When the mobile device  100  is interfaced with, for example, a car charger, the mobile device  100  can be made aware that it is in a car. The present invention can be implemented using these location determining schemes as well. 
         [0035]    The transfer of location information between system elements can be the result of various processes depending on the capabilities and functionality of the communication device  100 . These processes include, for example, a query of an on board GPS receiver of the communication device  100 , a request by the communication device  100  for location information from the LBS server  106 , or a “push” of location information to the communication device  100  by the LBS server  106  over the telecommunications network  102 . The location information can take any form sufficient to identify the location of the user, such as, x and y coordinate data, or latitude/longitude data. In some embodiments, coordinate data (or latitude/longitude) is not transferred to the communication device  100 , but is instead used by an external (external from the communication device  100 ) network element to determine a location of the device  100 . For example, the LBS server  106  can use coordinate location data for the device  100  to determine that the device is “at home” by using a lookup table or other cross-referencing method, and provide this information to the messaging server  132  to update an instant messaging presence of the user/device  100 . 
         [0036]    The system elements used to determine the location of the communication device depend on the method used. Some elements may not be required for some methods. For example, the Bluetooth related method and physical interfacing methods described above can be implemented without an LBS server  106 . In addition, in some embodiments location determination using GPS methods can be implemented without an LBS server  106 . 
         [0037]    Furthermore, some embodiments of the present invention do not require a location determination, instead relying on various device settings, such as device parameter settings, profile settings, or application settings such as instant messaging presence settings. 
         [0038]      FIG. 2  is a block diagram representation of the data storage unit  112  of the communication device  100 . The data storage unit  112  comprises an operating system  202 , which contains instructions for operating the communication device  100 . In addition to any other instructions, a program instructions unit  204  includes instructions, which when executed by the processing unit  110 , perform methods of the present invention. The program instructions unit can include a format conversion application for converting a communication from a first format into a second format and/or from a second format into a first format. Alternatively, format conversion operations can be performed by a network element external to the communication device  100 . A configuration data unit  206  can be included in the data storage unit  112  that contains various configuration information data. 
         [0039]    The data storage unit  112  can also contain a device settings unit  208 . The device settings unit  208  can contain various parameters indicating the settings of the communication device  100 . These parameters can include a value for indicating an instant messaging presence associated with the communication device  100 . Another parameter can be a communication format type. A communication format type can be associated with an instant messaging presence. Other device settings that can be stored in the device settings unit  208  include, but are not limited to, ring type, touch tone type, or appearance of the user interface  128 . The data storage unit  112  can optionally include a format conversion application  210 . 
         [0040]      FIG. 3  is a block diagram illustrating systems and methods of routing communications according to the present invention. Routing logic  302  has inputs for text communications  304 , speech communications  306 , device/application settings  308 , and device location  310 . It should be understood that the elements of  FIG. 3  can be implemented in hardware or software of the communication device  100  or in one or more network elements (external to the communication device), or a combination thereof. The routing logic  302  can reside in the communication device  100  or on a network element external to the device or a combination thereof. The routing logic can accept text or speech communications intended for the communication device  100  and route them based on the device/application settings  308  and/or the device location  310 . 
         [0041]    The routing logic  302  can route a text communication  324  to the text-to-speech converter  320  or route a text communication  318  directly to the device display  314  of the communication device  100 . The text-to-speech converter can be included in the format conversion server  134  of  FIG. 1  and/or the format conversion application  210  of  FIG. 2 . Routing logic  302  can route a speech communication  328  to the speech-to-text converter  322  or route a speech communication  316  directly to the device speaker  312  of the communication device  100 . The speech-to-text converter can be included in the format conversion server  134  of  FIG. 1  and/or the format conversion application  210  of  FIG. 2 . 
         [0042]    Text communications  324  routed to the text-to-speech converter  320  are converted to speech communications  326  and forwarded to the device speaker  312 . The text-to-speech converter can be a voice synthesizer that accepts text and outputs speech corresponding to the text communication being converted. The text-to-speech converter can be implemented in hardware, software, or a combination thereof. The text-to-speech converter can be implemented in the communication device  100 , in external network elements, or in a combination thereof. 
         [0043]    Speech communications  328  routed to the speech-to-text converter  322  are converted to text communications  330  and forwarded to the device display  314 . The speech-to-text converter can be voice recognition hardware or software that is capable of accepting human speech and outputting text that corresponds to the inputted speech. The speech-to-text converter can be implemented in hardware, software, or a combination thereof. The speech-to-text converter can be implemented in the communication device  100 , in external network elements, or in a combination thereof. 
         [0044]    It should be understood that the pathways depicted in  FIG. 3  can be wired interfaces or wireless interfaces. 
         [0045]    The routing logic  302  can operate to route communication intended for the communication device  100  according to user preferences/device settings, application settings, device location, or any combination thereof. A communication device  100  user, for example, can, through a device setting, indicate that text communications, such as SMS messages, are to be converted into speech communications before delivery to the communication device  100 . The device setting can be an individual setting or part of a device profile. This can be desirable where the user will be in a situation where the user cannot or should not focus their eyes on the display of a communication device to read a text communication. An example of such a situation is where the user is driving an automobile. Also, a user might be in a situation where both hands will be in use. A user might be working on a ladder, for example, where the user is in earshot of the device but unable to reach it. In such cases the communication device  100 , for example, can be set to play text converted to speech over a speaker of the communication device. Bright light conditions such as a sunny day on a lake might cause difficulty in reading a device display, in which ease a text-to-speech conversion can be desirable. Many other uses for such a feature will be apparent to one of ordinary skill in the art. 
         [0046]    Likewise, a user can, through a device setting, indicate that speech communications should be converted into text communications before output to the communication device  100 . This can be desirable in situations where the receipt of a speech communication would be impossible (for example, at a loud concert), socially improper (for example, in a church, movie theater, or business meeting), or the user is just not interested in taking calls at the time. 
         [0047]    In addition to a user indicating communication receipt preferences through device settings, application settings of device applications can be used to determine how communications should be routed to the communication device. A user may be, for example, listening to an audio player built into the device. The settings of the audio player application can instruct the routing logic  302  to route speech communications to the speech-to-text converter so as not to disturb the user. 
         [0048]    Another example is settings of an instant messenger application having an interface on the communication device  100 . Such applications have user presence information that can be set based on a number of factors including, but not limited to, manual user settings, current use of the device, and settings of an associated messenger application on the device itself or on another device (such as the user&#39;s personal computer). Further examples of instant messenger presence settings can be found in the related applications mentioned above which have been incorporated by reference. The instant messenger application&#39;s presence information can be used to determine how communications should be routed to the communication device  100 . For example, if the presence information indicates that the user is in a meeting, speech communications can be routed to the speech-to-text converter for delivery to the communication device. A presence setting of “in the car” can cause the routing logic  302  to route text communication to the text-to-speech converter for delivery to the communication device. 
         [0049]    The routing logic  302  can also route communications based on a device location. The device location can be determined using one or any combination of the methods described above. For example, upon the communication device arriving at the user&#39;s business office, the routing logic  302  can be configured to route speech communications to the speech-to-text converter. If the location of the device is rapidly changing (or has a threshold velocity, for example) the routing logic can be configured to presume that the user is in an automobile and route text communications to the text-to-speech converter (this may be undesirable if the user is a passenger in a car or is on a train, in which case the user can disable this feature). Bringing the device within the communication radius of a Bluetooth radio located at a movie theater, for example, can cause the routing logic  302  to forward speech communications to the speech-to-text converter  320 . 
         [0050]    It should be understood that the device and device applications can be configured to accept a device location instead of, or in addition to the device location being provided directly to the routing logic  302 . For example, the routing logic can route communications based on the settings of an instant messenger application as mentioned above. The instant messenger application setting can be based on a location of the device. It should be understood that text communications include text messages of an instant messenger application and speech communications include any speech communications or voice chat data of an instant messenger application. 
         [0051]    The routing logic can also route communications based on the settings of the communication device. The communication device  100  settings can be based on a location of the device. 
         [0052]      FIG. 4  shows a flowchart of a method  400  according to the present invention. This method can be implemented in hardware, software or a combination thereof and can be implemented in the communication device  100 , network elements external to the communication device  100 , or a combination thereof. The method begins at  402  and proceeds to  404  where a communication intended for the communication device  100  is received. At  406  the communication is checked to determine if the communication comprises a text format. If the communication comprises a text format, operation proceeds to  408 . If the communication does not comprise a text format, operation proceeds to  410  where the communication is checked to determine if the communication comprises a speech format. If the communication comprises a speech format, operation continues to  412 . If the communication does not comprise a speech format, operation proceeds to  414 . If  414  is reached, the communication does not comprise formats supported by the method and is delivered to the device unaltered, and the method ends at  416 . It should be understood that the method of  FIG. 4  is exemplary and additional formats can be added to the present invention. 
         [0053]    Returning to  408 , a query of device settings, application settings, and/or device location is performed. At  418 , the results of the query are checked to determine if the state of the device settings, application settings, and/or device location indicates that the device should receive speech only. This determination can be accomplished through the use of a lookup table, or any other logical method for mapping or associating a set of conditions to/with an outcome. Examples of possible logical arrangements are given below in Tables 1 through 4. If the data does not indicate that the device should receive speech only, operation continues to  420  where the text communication is delivered to the communication device display is its text format. The method then ends at  416 . If device should receive text only, the text message is converted into a speech format at  422 . The speech formatted message is then delivered to the communication device speaker at  424 . The method ends at  416 . 
         [0054]    Returning to  412 , a query of device settings, application settings, and/or device location is performed. At  426 , the results of the query are checked to determine if the state of the device settings, application settings, and/or device location indicates that the device should receive text only. This determination can be accomplished through the use of a lookup table, or any other logical method for mapping or associating a set of conditions to/with an outcome. Examples of possible logical arrangements are given below in Tables 1 through 4. If the data does not indicate that the device should receive text only, operation continues to  428  where the speech communication is delivered to the communication device speaker in its speech format. The method then ends at  416 . If device should receive text only, the speech message is converted into a text format at  430 . The text formatted message is then delivered to the communication device display at  432 . The method ends at  416 . 
         [0055]    It should be understood that the method  400  can be implemented as a loop such that the method continuously waits for incoming messages, performs conversion operations as needed, and again waits for incoming messages. 
         [0056]    Table 1 shows a set of relationships where a communication mode of a communication device is based on device settings.

         [0057]    Five device settings are shown in Table 1. Table 1 is exemplary and many more device settings can be used to determine a communication mode of the device. A “text only” or “speech only” device setting can be used to place the device in a corresponding communication mode. Profile settings for “silent”, “loud”, and “soft” can be mapped to communication modes according to user preferences. User preferences can be entered through a user interface of the communication device as is known in the art for setting other profile features, for example, the interface used for setting a ring tone corresponding to a given profile. In the example of Table 1, the device is set to receive text only when the device is in a “silent” profile. In the “soft” and “loud” profile, communications can be delivered as normal. That is, text delivered as text, and speech delivered as speech.

         [0060]    Locations such as “At Home”, at “Church”, and “At Office” can be configured through user preferences. For example, when the device is located at the user&#39;s home, the user can use an interface to define the current location as “At Home”. The user can provide a radius from the current location for which the “At Home” setting will apply, or this can be a fixed value for each location setting determined by the service provider. The “Not Stored” location refers to a location that the device does not recognize. For example, the device is located in an area that the user has not defined or the location of the device cannot be determined.

         [0062]    In the set of relationships shown in Table 4, priority is given to the device settings, then to the IM presence settings, and then to the device location in determining the communication mode of the device. The device settings of “Text Only” and “Speech Only” cause the communication mode to be set correspondingly. The “-” in the other columns indicates a logical “don&#39;t care”. In the remaining table entries, the device setting is set to “Normal”. 
         [0063]    Where the IM presence is set to “In Car” the location setting is ignored, and the communication mode is set to “Speech Only”.
