Patent Application
20060068752
The present invention relates in general to wireless communication units and wireless networks, and more specifically to providing alarm notifications via a wireless network to a wireless communication unit.
Certain equipment can be provided with a capability of generating alarms, relating for example to devices being monitored, generating alarms themselves, and/or to the equipment itself. For example, when equipment installed at an industrial site goes out of service, experiences a malfunction, or encounters certain conditions, the equipment can generate an alarm. Alarms are typically delivered, for example, from a console connected to one or more alarm generating devices. When personnel monitoring the alarms are positioned in the vicinity of the control system console, the personnel can adequately handle the alarms, and can rapidly receive information regarding the alarms. Hence, they can receive immediate notification about, for example, emergency situations.
When personnel is located remotely from the control system console, such as could happen when for example personnel are in the field or located at a distance from the console, personnel still desire rapid notification of alarm conditions. Even when personnel are located in the same area, alarming can be difficult due to noise levels.
The accompanying figures, where like reference numerals refer to identical or functionally similar elements and which together with the detailed description below are incorporated in and form part of the specification, serve to further illustrate a preferred embodiment and to explain various principles and advantages in accordance with the present invention.
In overview, the present disclosure concerns wireless communications devices or units, often referred to as communication units, such as cellular phones or two-way radios and the like having the operating capability for conveying communications, and the communication systems associated therewith, such as an Enterprise Network, a cellular Radio Access Network, or the like. Such communication systems may further provide services such as voice and data communications services. More particularly, various inventive concepts and principles are embodied in systems, communication units, and methods therein for communicating alarm notifications to a communication unit. It should be noted that the term communication unit might be used interchangeably herein with subscriber unit, wireless subscriber unit, wireless subscriber device or the like. Each of these terms denotes a device ordinarily associated with a user and typically a wireless mobile device that may be used with a public network, for example in accordance with a service agreement, or within a private network such as an enterprise network or a dispatch network. Examples of such units include personal digital assistants, personal assignment pads, and personal computers equipped for wireless operation, a cellular handset or device, or equivalents thereof provided such units are arranged and constructed for operation in appropriate networks.
The communication systems and communication units of particular interest are those providing or facilitating voice communications services or data or messaging services over cellular wide area networks (WANs), such as conventional two way systems and devices, various cellular phone systems including analog and digital cellular, CDMA (code division multiple access) and variants thereof, GSM (Global System for Mobile Communications), GPRS (General Packet Radio System), 2.5G and 3G systems such as UMTS (Universal Mobile Telecommunication Service) systems, Internet Protocol (IP) Wireless Wide Area Networks like 802.16, 802.20 or Flarion, integrated digital enhanced networks and variants or evolutions thereof.
Furthermore the wireless communication units or devices of interest can have short range wireless communications capability normally referred to as WLAN (wireless local area network) capabilities, such as IEEE 802.11, Bluetooth, or Hiper-Lan and the like preferably using CDMA, frequency hopping, OFDM (orthogonal frequency division multiplexing) or TDMA (Time Division Multiple Access) access technologies and one or more of various networking protocols, such as TCP/IP (Transmission Control Protocol/Internet Protocol), UDP/UP (Universal Datagram Protocol/Universal Protocol), IPX/SPX (Inter-Packet Exchange/Sequential Packet Exchange), Net BIOS (Network Basic Input Output System) or other protocol structures. Alternatively the wireless communication units or devices of interest may be connected to a LAN using protocols such as TCP/IP, UDP/UP, IPX/SPX, or Net BIOS via a hardwired interface such as a cable and/or a connector. More particularly, the wireless communication units or devices of interest can have a dispatch communication capability.
The instant disclosure is provided to further explain in an enabling fashion the best modes of performing one or more embodiments of the present invention. The disclosure is further offered to enhance an understanding and appreciation for the inventive principles and advantages thereof, rather than to limit in any manner the invention. The invention is defined solely by the appended claims including any amendments made during the pendency of this application and all equivalents of those claims as issued.
It is further understood that the use of relational terms such as first and second, and the like, if any, are used solely to distinguish one from another entity, item, or action without necessarily requiring or implying any actual such relationship or order between such entities, items or actions. The invention may include processes and/or steps, which can be performed in any order, unless expressly and necessarily limited to a particular order; thus processes or steps that are not so limited may be performed in any order.
Much of the inventive functionality and many of the inventive principles when implemented, are best supported with or in software or integrated circuits (ICs), such as a digital signal processor and software therefore or application specific ICs. The processor can be, for example, a general purpose computer, can be a specially programmed special purpose computer, can include a distributed computer system, and/or can include embedded systems. Similarly, the processing could be controlled by software instructions on one or more computer systems or processors, or could be partially or wholly implemented in hardware. It is expected that one of ordinary skill, notwithstanding possibly significant effort and many design choices motivated by, for example, available time, current technology, and economic considerations, when guided by the concepts and principles disclosed herein will be readily capable of generating such software instructions or ICs with minimal experimentation. Therefore, in the interest of brevity and minimization of any risk of obscuring the principles and concepts according to the present invention, further discussion of such software and ICs, if any, will be limited to the essentials with respect to the principles and concepts used by the preferred embodiments.
As further discussed herein below, various inventive principles and combinations thereof are advantageously employed to improve automatic notification of an alarm via a communication network.
Further in accordance with exemplary embodiments, a first server connects to certain devices, such as sensors, that can generate alarms. When the sensor needs to report an alarm, the alarm generator receives the sensed information and transmits the alarm to the first server. The first server transforms the alarm and associated information to, for example, voice information appropriate for use on a dispatch network, and makes a dispatch call request to a second server. The second server sends the requested dispatch call to the communication device. Based on, for example, alarm severity or other parameters, notifications can be sent to particular personnel or groups of users, and/or notifications can be escalated based on responses.

In accordance with one or more embodiments, the first server 103 can include, for example, an alarm interface (illustrated in
“Alarm generating equipment,” as used herein, is intended to refer to a wide variety of equipment that monitor device(s), including itself, and/or can receive alarm signals, and can generate a signal intended to advise of various device and/or environment and/or timing conditions and/or danger and/or a combination of the foregoing. An alarm can be generated electronically, mechanically, or electrically by the devices, and/or can be generated by the alarm generating equipment based on one or more alarms. Alarm generating equipment optionally generates an audible message or alert. Information regarding alarms optionally can be provided as text and/or images via a display in communication with the alarm generating equipment. Current technology typically provides that the alarm generating equipment transmits the alarm notification in a text format, although it is anticipated that alternative formats can be available and can be accommodated.
The first server 103 can receive the alarm notifications, for example via an alarm interface (illustrated in connection with
In accordance with one or more embodiments, the first server 103 can include a communication interface (illustrated in connection with
Further, according to one or more exemplary and alternative exemplary embodiments, the first server 103 can include a processor (illustrated in connection with
Further, the first server 103 can be configured to facilitate transforming the alarm notification to alarm information appropriate for being provided via a dispatch call, which can advantageously include audible signals and/or other information. For example, the alarm information can include text; the alarm notification can be converted from text to speech, e.g., in accordance with known techniques, and included as alarm information; the alarm notification can be associated with one or more pre-recorded text or audible notifications, e.g., as a recorded voice file in PCM (pulse code modulation) format, which is included in the alarm information; and/or can be a combination of the foregoing. According to one or more exemplary embodiments, the alarm notification can be converted and transmitted in the alarm information in a voice format for voice communication packets such as VSELP (vector sum excited linear prediction). In accordance with exemplary and alternative exemplary embodiments, the alarm information can be associated with other information, e.g., haptic, text and/or image data.
The server 103 can facilitate determining one or more recipients corresponding to one or more alarm notifications. It is anticipated that a server can be configured by a user to associate alarm notifications or data provided in alarm notifications, for example, types of equipment and/or types of alarms, or combinations thereof, with personnel. This can be provided, for example, in a database and/or a look-up table or other appropriate methods and devices. Such information can further include dispatch call information for use in facilitating the receipt of a dispatch call by the personnel, e.g., dispatch identification.
In accordance with one or more embodiments, the server 103 provides, in response to receipt of one or more alarm notifications, for transmitting one or more communications, in association with dispatch call information and alarm information, over the network to the recipient(s) of the communication(s). In accordance with one or more exemplary and alternative exemplary embodiments, the network can be, for example, the LAN/WAN network 105. In this situation, the first server 103 can be connected indirectly with the dispatch network 109 via the LAN/WAN network 105.
In accordance with one or more exemplary alternative embodiments, the first server 103 can be in more direct communication with the dispatch network 109. For example, if the first server includes a capability of communicating with the dispatch network 109, the communication can further be formed to be appropriate for transmission to a dispatch network, in order to generate one or more dispatch calls to the recipient(s)
In accordance with one or more embodiments and alternative embodiments, the first server 103 can associate the dispatch call information with an indication that the communication should be provided as a private call, a group call, a call alert, and/or an instant text message. Dispatch call information can be used in formatting the dispatch call requested that is transmitted to the dispatch network 109.
One or more embodiments provide that the first server 103 determines one or more recipients of a dispatch call including the alarm information in response to a priority of the alarm notification. An alarm notification can be associated with an indication of the priority of the alarm. It may be desirable to associate particular levels of alarm priority with particular personnel. This can be provided, for example, in a database and/or a look-up table or other appropriate methods and devices.
The first server 103 of one or more embodiments can be configured to facilitate simulating at least one subscriber of a dispatch call. For example, the communication that is ultimately transmitted to the dispatch network 109 can include subscriber information (for the first server) that corresponds to a permitted subscriber on the dispatch network, formatted in accordance with dispatch network specifications. If appropriate, the first server 103 can be configured to facilitate setting up other information necessary to simulate a subscriber, e.g., information provided via external tables.
In accordance with one or more exemplary alternative embodiments, the server 103 can provide for escalating a communication to a next level of authority in certain situations. For example, when one or more recipient(s) of a communication is determined to be non-responsive or has failed to respond in a pre-determined amount of time, or when an alarm is determined to be non-responsive to efforts to resolve, it may be desirable to provide for alternative personnel to be contacted in connection with the alarm information. For example, a communication to particular personnel can be determined to be successful by receipt of a return communication, or a communication (e.g., a dispatch call) received from the personnel. As another example, it may be desirable to escalate to other personnel when a next alarm notification is a part of a series of alarm notifications, and together indicate that the communication should be escalated to different personnel or group of personnel. Data utilized in determining escalation of communications, alarm notifications, personnel, and/or timing thereof can be advantageously stored as information and/or in a rules database.
One or more exemplary embodiments and alternative exemplary embodiments provide that the server 103 can receive a response from one or more recipients of communications. The response can include dispatch call information from the recipient, e.g., the dispatch caller identity and/or personnel information associated therewith, and/or content of the dispatch call, e.g., voice. Optionally, the server 103 can record and store such responses, for example for later review, search, retrieval, and or study.
The servers as described herein can store collected information in a database. A database can be located on local internal drives, local external drives, network attached storage (NAS), a storage area network (SAN), etc. The various databases may be in, for example, a UNIX format, but other standard or special purpose data formats may be used. The database optionally is distributed and/or networked.
In accordance with one or more embodiments, it may be desirable for the first server 103 to provide storage of rules establishing one or more first recipients corresponding to the alarm notification and/or the priority of the alarm notification. Moreover, the rules can establish one or more second recipients corresponding to the one alarm notification and a time delay to be applied, for example prior to contacting the second recipient.
The first server 103 can be configured more particularly to provide a dispatch call setup request prior to transmitting the dispatch call request, and to transmit a dispatch call termination request, subsequent to transmitting the dispatch call request. The dispatch call setup request, the dispatch call request and/or the dispatch call termination request can be transmitted over the communication network 105.
In accordance with one or more embodiments, the recipient or group or recipients that are to receive an alarm notification can be determined dynamically by the first server 103. For example, the recipients available for receipt of alarm notifications can be determined based on time of day, day of week, work schedule, vacation schedule, etc. As another example, the recipients for alarm notifications can be determined based on whether the recipient has already received a maximum number of alarm notifications. As a further example, recipients can be determined dynamically by grouping recipients by location of alarm notifications, whereby recipients can more readily physically check co-located alarm notifications.
In accordance with one or more embodiments, the second server 107 can include a first communication interface (illustrated in
The second server 107, for example operating in response to the first server 103, can be configured to transform a dispatch call request appropriate for communication over a computer network, e.g., the LAN/WAN network 105, into a dispatch call appropriate for transmission over the dispatch network 109. In accordance with one or more embodiments, the second server 107 receives one or more dispatch call requests via the first communication interface. The second server 107 also transmits a dispatch call over the dispatch network 109 via the second communication interface.
The second server 107 can be configured to transform the dispatch call requests it receives into dispatch calls that can be recognized by the dispatch network 109. The dispatch call request may include information necessary and/or desirable for formatting a dispatch call, and includes content to be included in the dispatch call. The dispatch call request may include, as discussed previously, for example, dispatch call information and alarm information, to assist in formation of the dispatch call to the desired recipients. Dispatch call information may include, for example, subscriber information to indicate or simulate the originator of the call (e.g., the first server 103). Utilizing the dispatch call information, the second server 107 prepares a dispatch call in accordance with known formats therefore, and transmits the dispatch call to the dispatch network 109.
The dispatch call can be, for example, a private call, a group call, a call alert, and/or an instant text message. An indicator can be included in the dispatch call request corresponding to the type of dispatch call.
The second server 107 can be configured to provide the dispatch call so that it appears to be a normal dispatch call to the dispatch network 109. For example, the second server 107 can be configured in accordance with known techniques to simulate a cell site with respect to the dispatch network 109. Further, the second server 107 can simulate the type of dispatch call, corresponding to the indicator in the dispatch call request. For example, where the type of dispatch call is a group call, the second server 107 can cause the call to appear to be a group call, thereby causing the dispatch network 109 to utilize its known techniques of duplication and parallel signal distribution, e.g., on the same time slot, to the recipients in the group.
According to one or more exemplary embodiments and alternative exemplary embodiments, the recipient can call back to notify the system that the alarm notification has been handled. For example, the second server 107 can receive a dispatch call from one of the communication devices 113, 115 via the dispatch network 109; can transform the dispatch call into a communication for a computer network communication by applying principles discussed previously; and can transmit the communication to the first server 103 via the computer network, e.g., the LAN/WAN network 105.
In accordance with one or more embodiments, the second server 107 can be further configured to facilitate transmitting and/or receiving calls over the dispatch network in accordance with the expected procedures. For example, the second server 107 can be configured more particularly to receive a dispatch call setup request over the communication network, e.g., the LAN/WAN network 105, and in response, to transmit a dispatch call setup request to the dispatch network 109. Moreover, the second server 107 can be configured to transmit a dispatch call termination to the dispatch network 109 in response to receipt of a dispatch call termination request.
