    CROSS REFERENCE ON RELATED REQUEST
    This application relates to co-pending US Patent Applications, Serial No. 12/749,194 (Legal Protocol Number CM13257) and Serial No. 12/749,142 (Legal Protocol Number CM13304), filed concurrently with it and commonly assigned to Motorola , Inc. FIELD OF EXHIBITION
    The present presentation is generally concerned with communication systems, and, more particularly, with the improvement of mission-critical and business-critical communication systems, through the provision of an enhanced emergency and backup request capability using a plurality of communication devices. BACKGROUND
    Public safety personnel such as police officers, firefighters, paramedics and the like, as well as critical commercial users such as industrial, hospital and public service workers typically use multiple communication devices. While some of these devices can operate on government or enterprise networks with emergency capabilities, others cannot.
    Public safety communication devices include, for example, mobile radios such as portable radios and/or vehicular radios along with remote accessories such as remote microphones, speakers, headsets, headsets and the like. This type of equipment (considered primary mission critical devices) and the infrastructure to support its operation are typically carried out using a Private Network governed by a public safety agency. Primary devices for use in mission critical applications often include a user interface having an emergency button for transmitting an emergency alert notification, as well as a push-to-talk (PTT) capability that allows a worker to request additional backup features in high-stress situations.
    Additional non-public safety types of devices frequently used by public safety personnel are considered non-mission critical devices, such as cell phones, personal digital assistants, electronic notepads which operate over a Public Concessionaire network. These secondary non-mission critical devices do not provide the user with an interface to high voltage emergency environments.
    Public safety personnel often ask for backup resources in a dangerous situation. However, when PTT voice requests for backup features are communicated over a radio system or a cellular network, the requests may not be heard by dispatchers or co-workers due to holes in coverage, network congestion, conversations or focus of the co-worker's task. The public safety worker who presses the emergency button or push-to-talk button to request backup may not be able to readily repeat the request when operating in a high voltage situation. Additionally, the public security worker may not be aware that the request failed, further jeopardizing security.
    As such, there is a need for an improved communication system that improves emergency and enforcement requests in public safety applications. BRIEF DESCRIPTION OF THE FIGURES

    Before describing in detail embodiments that are in accordance with the present invention, it should be noted that the embodiments primarily reside in combinations of apparatus components and method steps related to improving a mission or business critical communication system. While the mobile communication system provided here applies to a variety of users who carry multiple devices, the public safety examples will be used to illustrate various embodiments of the invention.
    In the description herein, numerous specific examples are given to provide a complete understanding of various embodiments of the invention. The examples are included for illustrative purposes only and are not intended to be exhaustive or to limit the invention in any way. It should be noted that several equivalent modifications are possible within the spirit and scope of the present invention. One skilled in the relevant art will recognize, however, that an embodiment of the invention can be practiced with or without the apparatus, systems, assemblies, methods, components mentioned in the description.
    Figure 1 is a diagram of a communication system 100 formed and operating in accordance with an embodiment of the invention. The communication system 100 comprises a plurality of communication devices 110, 112, 114, 116, 120, 130 shown operating under a plurality of different wide area communication networks shown as the P25 network 140 and the broadband network 142. A computer-aided dispatch (CAD) center 144 and a radio console 146 communicate with a plurality of communication devices 110, 112, 114, 116, 120, and 130 over wide area networks 140, 142. communication system 100 can be used by a single user 101 and/or a co-located user 102 and further with external users 103, 104. The communication devices are shown as a radio 110, a PDA 112, a vehicular computer with camera 114 , a vehicle radio 116, and an accessory 160, and these communication devices are under the control of the first user 101. The communication device 120 is shown as a PDA under the control of the second user 102. The communication device 130 is shown as a cellular telephone under the control of a third user 103. According to the embodiment, the communication devices under the control of the first user 101 and the second user 102 are operating in a personal area network (PAN) 150 , while the third user 103 is using a communication device 130 outside of PAN 150. The CAD center 144 and radio console 146 are outside of PAN 150 and are under the control of a dispatcher, a fourth user 104.
    According to the modality, the plurality of communication devices 110, 112, 114, 116, 120, 130 have an emergency application stored there that provides for collaborative operation among the devices when they are in range of the personal area network ( PAN) 150. As such, in Figure 1, the third user 103 is currently shown outside the PAN 150 area, although the communication device 130 is still communicating over the public broadband network 142.
    According to the embodiment of figure 1, at least one communication device, here the communication device 110, comprises a two-way radio with push-to-talk (PTT) and text messaging capability operating over a network of a narrowband network, such as the P25 network 140. At least one other communication device 120, shown as a personal digital assistant (PDA), operates over the public broadband network 142 and provides emergency, PTT, message sending capabilities. text, telephony and computer-aided dispatch (CAD) of client / mobile client.
    According to an embodiment, at least one of the plurality of communication devices comprises an emergency detection feature triggered, for example, by: an input device, a keyboard, an emergency alert button, voice recognition, alarm sensor. emergency, accelerometer, down man detection with mercury switch, and/or biometrics through an accessory. For the purposes of example, two-way radio 110 is shown as including the emergency button and PDA 120 is shown as including the emergency button. It should be noted that although devices 110, 120 have a collaborative emergency app, only one device needs the emergency detection capability.
    Additional devices operating on the P25 140 network may include, for example, a server, additional computer-aided dispatch (CAD) consoles, additional radio consoles and/or other two-way radios, to name a few. Additional devices operating on broadband network 142 may include other data devices having text messaging, client consoles such as a computer aided console (CAD) dispatch console, telephony devices such as a device cell 130 used by independent user 103 and PTT devices, to name a few. Additional communication devices, such as an accessory device 160, may also form part of the plurality of communication devices for operation with communication devices 110, 112 and 114. For the purposes of description in Figure 1, the cellular telephone 130, the CAD console 144 and the radio console 146 are considered external to the PAN 150 network and may also be referred to as a plurality of external communication devices. Additional elements (not shown) may also be operating on the PAN 150 network, for example a mobile CAD console in the vehicle.
    According to the embodiment of Figure 1, the plurality of communication devices 110, 112, 114, 116, 120, 160 operate over the personal area network (PAN) 150. The PAN operates simultaneously with the wide area network (WAN) of the P25 network 140 and the public broadband network 142. Pairing of the plurality of devices with PAN initiation can be initiated, for example, at the beginning of a user shift and operate continuously. According to the modality, the plurality of communication devices 110, 112, 114, 116, 120 collaborate by PAN 150 and reconfigure each other for operation in an emergency operating mode in response to the emergency condition being detected. When an emergency condition has been detected on radio 110, for example, if a PTT voice communication fails to result in a successful communication or if an emergency button press fails to result in a successful communication, then the radio 110 will instruct the PDA 112 to operate in an emergency operating mode and transfer the emergency content to the PDA 112 so that the PDA 112 can initiate a new communication using the emergency content using the same type of communication or a alternative. The PDA 112 can, for example, transfer the emergency content to other devices, such as the PDA 120, the CAD console 144. The CAD console 144 in turn can transfer the emergency content over all networks, such as , for example, to the external communication device 130 of the third user 103.
    In another embodiment, if emergency mode originates from PDA 112, then PDA will automatically notify radio 110 to enter an emergency mode, and PDA 112 will provide emergency content information to radio 110. radio 110 then operates as thinking its emergency button or the PTT button was pressed, sending the received emergency content from the PDA 112 and having a PTT voice communication.
    According to an embodiment, at least one of the plurality of communication devices 110, 112 provides an emergency detection and an emergency notification to other communication devices in the communication system 100. During the collaborative mode of emergency operation, an information is collected, shared and joined among the plurality of communication devices and then transmitted through the plurality of different communication networks 140, 142, thereby providing redundant emergency transmissions across the plurality of networks and/or types of Communication. As mentioned above, accessory 160 can be included and used to transfer emergency information among the plurality of communication devices via PAN 50. Redundant transmission of emergency information ensures that all backup personnel associated with the user are notified of the emergency conditions, including users of radio console 146, CAD console 144, telephony, user PTT fault group members, text messaging clients, email clients and/or mail clients. mobile data. As such, communication devices external to PAN 150, such as Computer Aided Dispatcher (CAD) consoles 144, radio computer consoles 146 and/or other external devices operating on the different communication networks 140, 142 can be upgraded in parallel with redundant transmissions.
    According to one modality, a reconfiguration of the plurality of communication devices is pre-configured by the collaborating emergency applications. Collaboration emergency apps can be built into communication devices 110, 112, 114, 116, 120, 130 or added as a user app. This emergency app can be a separate app or employed as part of a CAD/mobile client or a PTT client running on the device. However, once the customer is an employee, the user or a system administrator can configure it according to the business rules agreed by the customer. For example, an officer could configure the emergency app to take emergency content generated by PTT calls on radio 110 and send a text message to all members in their PTT talkgroup with the same content. They can also allow a dispatch operator or supervisor to transfer (via upload) officer location and sensor data when in an emergency mode. Business rules can also be regulated to place PDAs 112, 120 in a speakerphone or auto-answer mode, or have the PDA application require higher levels of network service, if this feature is supported on the networks used.
    The emergency information captured by the emergency application can comprise, for example: voice clips, location information, sensor data and text, collected by at least one of the plurality of communication devices. According to a PTT modality, an emergency information may take the form of an emergency voice PTT information collected on a radio microphone 110 and the PDA device 112. For example, the microphone may be used to collect a voice communication in response to the PTT button being pressed. When the PTT button is pressed, voice information is stored in a circular buffer. If an emergency is detected, this voice buffer will be treated as emergency content. PTT information will be treated as emergency information if an emergency is detected. On PDA or even radio, audio can be constantly stored in a circular buffer, even if the user is not on a "call" . The buffer can then be used as emergency content if an emergency is detected.
    Information for dissemination among the plurality of external communication devices 130, 144, 146 can occur in at least two ways, such as two PTT applications collaborating in an emergency mode, and taking voice clips from a device and starting a new PTT on a second device with the voice clip, or standalone emergency apps running on each device for the purpose of exchanging emergency content which, in turn, interface with other apps on their respective devices, converting a content to a form suitable for other applications as needed.
    Emergency voice PTT information can be converted by the emergency application into a combination of data (eg text messages) and/or voice clips which are transmitted to other communication devices using non-voice communication. PTT. The non-PTT communication may comprise, for example, a short text message service (SMS) message, a CAD message/mobile client, a multimedia message service (MMS) or other non-PTT communication means.
    During the collaborative mode of operation, the plurality of communication devices 110, 112, 114, 116, 120 can also append the emergency information received from the collaboration device with a location information, image, sensor, photo, audio recording, last call, incident assignment or other emergency information concerning the user, before transmitting the emergency information to other communication devices.
    As an example, consider a police officer (eg first user 101) in the field pressing the PTT button on radio 110. The officer speaks into the microphone declaring his emergency condition, eg "I need backup - there is three gang members with guns!!". The radio emergency application operating under this mode detects that the communication has failed (eg the unit was out of coverage, or the user has talked to the APCO 25 system) and that this is an emergency communication. The radio emergency application notifies the PDA 112, which allows the emergency mode to activate and the radio 110 sends a relevant emergency information to the PDA 112. The relevant emergency information content may take the form of a clip voice data, GPS data, sensor data and the like as described above.
    Continuing with the example, the PDA 112 automatically and periodically dials a telephone call to the officer's supervisor, such as the third user 103. The content of the call includes the programmed voice communication below "Officer Smith has requested backup, but this communication Officer Smith declared "I need backup - there are three gang members with guns." Call content may even include voice location information based on GPS coordinates generated on Radio 110 or PDA 112 and translated to voice on the PDA 120. For example, call content might include "Official Smith is located at SW 4thStreet and 75th avenue
    Additionally, the call content may include information regarding background noise surrounding one of the communication devices. For example, if gunshots were detected by radio 110 or PDA 112, then the content of the call could also include "Shots were detected." as a voice clip generated from the emergency app.
    The dispatcher can continue to listen to the officer's surroundings and speak to the officer through the PDA speaker, which would have been automatically activated in response to the activation emergency mode. Text messages can also be sent to anyone in the current talkgroup with the same information.
    Emergency mode will terminate when a satisfactory response is generated. A satisfactory response may be for the call to be answered or for the PDA 112 to receive and respond to a callback from a supervisor (eg, third user 103 or dispatcher 144). The satisfactory response is then communicated to the radio emergency application.
    As another example, consider a police officer pressing the emergency button on the PDA 112 and declaring "Backup needed - three gang members with guns!!". In response to the emergency button being pressed on the PDA 112, a PDA emergency application of the PDA 112 is enabled, which notifies the radio 110 to enable its radio emergency application. Alternatively, the emergency button can also be located on a wearable accessory, such as accessory 160 (shared by both communication devices 110, 112), and can include a sensor, or be driven by analyses. Once the PDA emergency application is activated, the relevant emergency information content (eg a voice clip, GPS data converted to voice, sensor data converted to voice, to name a few) is transferred to the radio emergency app. The official's buffered/stored voice is then transmitted from radio 110 as a PTT voice communication and the radio emergency functionality is invoked - as if the emergency button on radio 110 had been pressed.
    Accompanying voice communications can also be provided by the use of a PDA 112 microphone input, with a "virtual" push-button PTT based voice recognition software on the PDA 112, which detects when the officer is speaking , stores the content and forwards the content as data (or voice) to the PTT radio 110, for radio transmission. Then, every time the user's voice is detected when in an emergency mode, the microphone will capture the voice and buffer it, so the emergency application would initiate a PTT or other communication with the user's voice, along with a preface, if desired.
    With reference to Figure 2, there is shown a flowchart 200 providing an example of how the communication system operating in accordance with an embodiment of the invention enters predetermined modes of operation. Briefly, according to this modality, the predetermined operating modes comprise the emergency operating mode or an alternative communication mode entered based on predetermined business rules. Entering either of the two modes of operation is based on accumulating a context information surrounding the plurality of communication devices, receiving a trigger, and receiving a satisfactory or unsatisfactory response to the trigger.
    Starting at 202, context information currently associated with at least one of the communication devices (such as devices 110, 112) is accumulated and temporarily stored or buffered. The accumulated context information can be in the form of a user voice, background audio, sensor data, location, visual or any other context type information. For example, sensor data can be acquired using a variety of sensor types, including environmental sensors, motion sensors, biometric sensors, and the like. The content of the context information is examined to determine if an emergency condition exists, thereby triggering an emergency detection response at 204. Alternatively, a trigger at 204 may be initiated based on an emergency button press or a push of PTT from any device.
    At 206, a response check is made to indicate whether an emergency condition has been satisfactorily resolved. A response check may require user action to indicate that the emergency condition has been resolved or was an error. If an unsatisfactory response is received at 206, then the plurality of communication devices 110, 112, 114, 116, 120 and 160 will be placed in the emergency operating mode at 208. The plurality of communication devices will remain in the operating mode until a satisfactory response is received. Examples of satisfactory response include, for example, a call being answered by radio 110 or PDA 112 receiving and responding to a return call from a supervisor or dispatcher.
    During emergency mode of operation, the plurality of communication devices operate in the collaborative manner described previously. A satisfactory response at 206 indicates that no emergency condition exists, and a decision is made as to whether to invoke an alternative communication, based on business rules predetermined in 210. If the decision to invoke an alternative communication is made in 210, then alternative communication will be invoked at 212.
    Figure 3 is a flowchart 300 providing an example of content delivery in an emergency mode of operation in accordance with an embodiment of the invention. Step 302 is the equivalent of 208 from Fig. 2 where all communication devices are placed in an emergency mode of operation. If an emergency button press or other emergency indicator is not detected at 304, the buffer contents will be checked at 310 and relevant information will be selected and distributed among the communication devices at 312. If an emergency button press is detected at 304, then an emergency information, for example in the form of a user voice clip, will be obtained from the buffer.
    According to an embodiment, once emergency information is ready for distribution from 306 or 312, then transmission of the relevant emergency information to an individual or group is based on predetermined business rules. For example, with reference to 308, a voice clip can be associated with text, such as by converting the voice clip to text or attaching the voice clip to a text message. Types of additional information that can be attached to the text message include, for example, location, sensor data or other emergency information. A distribution of relevant emergency information can occur by initiating a telephone call using the buffered relevant emergency information. Transmitting relevant emergency information may also include requesting a companion device to initiate emergency communications using the relevant emergency information.
    Again, by sharing and appending emergency information among the plurality of communication devices, before or in conjunction with the emergency information being transmitted across multiple networks and various types of communication, it facilitates a parallel propagation of emergency information. relevant emergency. The redundancy provided by propagating relevant information in a parallel manner improves the security and confidence of individuals working on the system.
    Fig. 4 is an example flowchart summarizing the improved emergency information distribution in the communication system according to an embodiment of the invention. Step 402 begins with detecting an emergency condition (based on PTT or an emergency button press) on a communication device, followed by 404 with the collection of an emergency information regarding the emergency condition. The collected emergency information is analyzed at 406 to determine relevant emergency information. Relevant emergency information is transferred to a plurality of communication devices by a personal area network at 408 .
    As an alternative, steps 402 and 404 can be interchanged if the emergency application transferred (via download) to the communication device initiates the accumulation of a public safety information (e.g. sensor data, as described above in step 202, and/or camera data, as seen in Figure 1), prior to detection of an emergency trigger.
    Moving to 410, the relevant emergency information is transmitted from the plurality of communication devices to external communication devices by multiple communication networks as a new communication session, thereby propagating a redundant transmission of the device information. specific mobile station 1. The propagation of relevant emergency information and the types of communication (eg phone call, text message, PTT call) employed are based on predetermined business rules. Relevant emergency information can be shared, appended and added by all collaboration devices as provided by predetermined business rules. Once a satisfactory response is detected by any of the collaboration devices, the other devices are notified and the devices return to standby operating modes.
    Accordingly, a communication system with enhanced security has been provided by providing a redundant propagation of emergency information across a plurality of devices and across a plurality of communication systems. Public safety workers can better manage, coordinate and utilize their communication devices due to the collaboration provided by the emergency mode of operation. Automatic transfer of relevant emergency information allows co-workers and outside systems to better monitor conditions and track public service personnel working in hazardous environments.
