Description

200407006 (1) Description of the invention: [Technical field to which the invention belongs] The present invention relates to an action-aware computer system, and more particularly to a system and method for reducing power consumption of an action-aware computer system. [Previous Technology] Many computer systems are designed to target the mobile user market, such as mobile phones and personal digital assistants (PDAs) using Palm OS or Microsoft Pocket PC operating systems. These mobile systems provide mobile users Xu Da daily applications, such as schedules, reminders, to-do list warning applications, and so on. Most commercially available applications only sense time, for example, the schedule application will notify users at scheduled times. However, most of the affairs in life occur in response to certain environmental situations according to their use. We use the word “environment” to indicate these situations, and time is only one of many environments. There are many other conditions in real life, such as temperature, lighting conditions, "in a conference room", and so on. The most important environment related to mobile applications is the mobile context (m0biHty context), which is usually classified into absolute position and relative position, hereinafter referred to as location context and proximity context (pr0ximity context). Applications that can detect certain environmental changes or exist and respond to the environment are called context aware applications, and environment aware applications that sense the mobile environment should be called mobility aware applications. Action-aware applications that sense absolute positions are called location-aware applications, and action-aware applications that sense relative positions are called proximity awareness applications, and many studies have been completed on action-aware applications. Some applications perceive absolute position by using radio waves to determine

This system requires a positioning system (such as ㈣) to be used with a personal digital assistant (PDA), thus increasing manufacturing costs and battery consumption. All these foot systems are used indoors or in tall buildings in Deng District. And pg: or attributable to operation-some applications invented exclusive radio wave transmission and reception to help determine the location of mobile stations, such as AT & T's Bad ^ System. Some applications sense the relative position, that is, the presence of other users (or actually their mobile devices) in the vicinity. These environment-aware applications are called proximity-aware applications. Each proximity-aware application uses a discover method to Find each other nearby. Some applications have dedicated radio wave transceivers that broadcast the C device identification code or user identification code periodically. Other devices nearby can exist, such as the Proxy Lady system of the Swedish Victoria Institution. Some applications rely on wireless network communication (such as 802Ub, etc.) to establish a connection. For example, the GUIDE system at Lancaster University in the UK uses a unitary wireless network architecture to provide location information to mobile units. The Proem system at the University of Oliver in the United States is an analytic proximity-aware application that defines an application-layer connection based on existing communication protocols (such as TCP / IP, UDP, or HTTP). After establishing a network connection with a special network system, Proem

O: \ 87 \ 87685.DOC -6-200407006 systems can discover each other. After the network connection is established, the presence manager in the Pr0em system is responsible for announcing its existence and exploring nearby peers. . However, the establishment of a network data connection must go through the authentication process of a higher network communication protocol, which is not convenient in use. If the 2 authentication process is relaxed, security protection problems will occur. Each type of environment has many different values or states (hereinafter referred to as "environmental state"). For example, temperature is an environment type, and 76 degrees c is a state of the environment. "It's an environment of sadness, and" not nearby "is another state. The entire space of a type of environment (hereinafter referred to as "environment space") is a combination of all possible states in that type of environment. Because the environment is dynamic, environment-aware applications must monitor their environment to provide timely responses. Due to Λ, the system used in the previous technology must be powered on directly. However, because the environment-aware application only senses and responds to certain special environmental states (hereinafter referred to as "trigger states"), the application spends most of its time in Monitor the environment, not the response environment. Most mobile environment-aware applications are used in mobile computer devices with limited power resources (such as batteries). If the power consumption is not considered, environmental-aware applications will become impractical. None of the existing environmental awareness systems address this issue. "Xun Industry has used a variety of power management strategies to reduce computer consumption α to protect our environment. These strategies« gate the circuit clock, turn off the power in the circuit block of the computer chip, and reduce the power in the computer. From the power consumption of cattle (such as hard disks) to shutting down the entire computer, many different ways have been used to implement management strategies (in hardware, firmware, or software). Generally, power at the computer system level Management strategy on unused computers

Wake up ”Hearts” Each power management strategy has its own wake-up method. For example, the user schedules a task to shut down the computer at night and wakes the computer up at early hours. This method is implemented by a computer or clock mechanism to monitor, exhaust, and shut down and wake up the computer system at special times. An application used to manage the power of computers on the network is called "Magic Packet Technology" or "Wake Up Online" (^ VLLAN; W0L). When the power supply to the computer system is stopped, the network interface in the computer system with online wake-up function will still consume a small amount of power. To wake up the computer system, a special format packet is transmitted to the network interface. The special format packet includes the network media access control (MAC) address of the receiving network J 丨 surface to be awakened. However, the wakeup The intent begins with the network interface of the sender of the packet. The previous techniques of the power-saving methods are not sufficient for mobile-aware applications. For example, U.S. Patent No. 6,177,905 must keep its host system and sensors alive to continue to monitor the current position and trigger the user's work when the current position falls within a preselected area. Because the presence manager of the Proem system relies on the data link and peak layer of the ad hoc network, and the network layer is usually executed on the host system, the Proem system must also make the host system And the web interface remains enabled. All previous technologies in mobile-aware applications keep the system enabled while monitoring the environment, but the application only needs to take into account some environmental conditions.

In all previous technologies, a 'situational sensor or receiver (such as a GPS receiver and wireless network interface) continuously transmits all states in the environment space to the environment-aware application 2 and lets the application decide how to respond. If the environmental status and applications "," off the meeting! "Cheng Cheng should process ^ and unnecessary activities occur on the operation line. [Summary of the invention] The present invention provides a power-saving action environment-aware computer system and Method, the clothing-awareness-removal system is a computer system including at least one processing unit and at least one mobile environment receiving device (MCRD) capable of detecting a mobile environment. The mobile environment includes a location environment and a proximity environment. The location environment is related to the absolute position in the reference positioning system, and the proximity environment is related to the relative position between objects. A link is set between the processing unit and the MCRD to provide a memory for accessing the memory in the MCRD. The environment-aware application executed by the ▲ processing unit selects one or more special conditions (hereinafter referred to as "trigger conditions") of the mobile environment and associates one or more tasks with each trigger condition. Then the application stores the trigger conditions in the memory of the MCRD via the link, and the MCRD can detect the mobile environment * motion 'and signal the application interpretation when the current state of the mobile environment meets the trigger conditions . After the environment-aware application receives the signal, it performs one or more of the tasks associated with the trigger conditions, separating the frame detection from the application to reduce a large amount of power consumption on the processing unit and activity. To further reduce power consumption, if the processing unit

O: \ 87 \ 87685.DOC 200407006 jNo activity, the processing unit can enter a power saving mode. When the processing unit is turned off, m MCRD is still being executed and consumes a great deal of private power from the power supply (such as a battery, etc.) to perform environmental detection. Before the processing unit is signaled to find a complementary trigger condition, if the processing unit is in the power saving mode, the signal will raise the power supply level in the processing unit. A preferred MCRD for sensing the location environment of the present invention includes a location receiver (such as a global positioning system (GPS) receiver), at least one checker, to I-memory ', and an interface controller. The interface controller receives several instructions to store the waiting-or-triggering area in the memory towel; the position receiver continuously or periodically detects the current position of MCRD; the checker compares the current position with the current position If the current position is in one of the trigger areas, a signal is generated. A preferred mcrd & perceptual proximity environment of the present invention includes a wireless communication interface (WCI) conforming to a communication communication protocol (such as Bluetooth or IEEE 802.n), at least one checker, at least one memory, And an interface controller. The controller receives several orders and shoots into the memory with a slab of material. The 'reduction condition' is the existence rule of other WCIs. In this existence rule, the identification code of each WCI is the trigger identification code. -Simple rules of existence can only be used for other WCI 4 codes. More complex rules of existence can be several, other WCI Bollinger equations, such as "A & B" is the condition that WCI A and WCIB coexist. In the other example, "A &! C" is State A exists but loses (i.e., speculative for some time) the condition of wci c. Messages carried on wireless media are identified by one or more identifiers (such as a transmitter).

The wireless communication interface continuously or periodically receives messages from the wireless media, and decodes the identifier bits of the message U. The child checker receives the one or more identification codes decoded by the message, and treats the WCIs designated by the received identification codes as being present. The child checker then evaluates these presence rules, and if there are—existence rules that meet the current existence of the WCI, the checker outputs a signal. In another embodiment, the checker records the last reception time of a trigger identification code, and the last reception time of the right trigger identification code is within a certain period of time from now on, then the WCI specified by the trigger identification code is treated as [Embodiment] The environment-triggered job (hereinafter referred to as "job") used here indicates that when the = brain processing device (hereinafter referred to as "computer device") detects -environment-triggered dagger, 1% A task or group of work scheduled by an environment-aware application.

Such work. System 0100 is generally implemented using any Baiji general-purpose computer, which has conventional electrical components, including at least one processor 0101, program memory 0102, at least one input device 0103, and at least-output device 0104 At least one mobile environment receiving device (MCRD) 0105.

Generally, the processor 0101, the program memory to 0102 system bus 0109 and the bus controller are regarded as the host system 0120 'and the other parts are regarded as peripheral devices. In some embodiments, a mobile computer device (such as a personal digital assistant (pDA), a mobile phone, or a portable computer, etc.) of the 0100 series can omit at least one component (such as a hard disk drive) of a conventional general-purpose computer.

Mobile environment The action environment includes a location environment and a proximity environment. The location environment is the position of the system in the reference positioning system, and the proximity environment is the original environment.

O: \ 87 \ 87685.DOC -12-200407006 The close relationship between the invention system and other objects or systems.

Location-Aware MCRD FIG. 2 depicts a preferred embodiment of the present invention for sensing location environment. The embodiment includes a host system and a location-aware MCRD. The MCRD is connected to the host system via a link (an I / O bus). The MCRD 0200 includes a GPS signal processor 0201, a checker 0202, an interface controller 0203, and a memory 0204. The signal processor receives signals from multiple satellites and uses triangulation to determine its position. The one-position reed system consists of longitude, latitude, and longitude. An environment-aware application 0108 on the host system receives one or more tasks and a trigger zone for each task from a user or other application. Then the application program 010 instructs the interface controller 0023 to store the trigger areas in the memory 0204 via the bus. The signal processor 0201 calculates and updates the current position continuously or periodically. The checker 022 then compares the current position with the trigger areas in the memory 0204. When the current position falls within the range of any trigger zone in the memory 0204, the checker 0220 generates a trigger signal to notify the application program 0 丨 〇8. The MCRD 0200 and host system 0120 can enter power saving mode independently. This power saving mode means stopping power or entering sleep mode with low or no activity. To reduce power consumption, the host system 0120 can enter power saving mode when there is no activity. Before notifying the application 0108, if the host system is in the power saving mode, the trigger signal can wake the host system first. The application program 0 1 can register an interrupt service in the host system 0120, and the host system 0120 executes the interrupt service when it receives the trigger signal. The interrupt service capture triggers the trigger area.

O: \ 87 \ 87685.DOC -13- 200407006 and passed to the application 108. In another embodiment, the interrupt service can retrieve the current location, and the application program can find out the trigger area triggered by itself. After the application 0108 receives the triggered trigger zone, it executes the work associated with the triggered trigger zone. With interrupt service, the application 0108 responds quickly to environmental changes without introducing unnecessary activities to monitor the environment. The trigger zone information may also include an identification code (such as a number) provided by the environment-aware application, and the interruption service may only notify the environment-aware application of one or more identifiers of the triggered area. In the example of Fig. 2, the MCRD is a GPS receiver as a positioning device. However, any positioning device may be used as the MCRD for detecting the location environment in the present invention. The MCRD can implement any foot technique known to those skilled in the art. Positioning technologies include mobile phone-based, mobile-assisted-based, network-based, and network-assisted-based positioning technologies. In mobile phone-based technology, the system spontaneously performs position calculations, such as the Global Positioning System (GPS); in mobile phone-based technology, the system performs some auxiliary actions for positioning, and the network (or network) Servers on the road) perform actual position calculations such as Enhanced Observation Time Difference (E-OTD). In the network-based technology, the network performs actual position calculations, such as time of arrival (T0A); in the network-assisted-based technology, the network provides some auxiliary actions for positioning, and the system performs position calculations , Such as A-GPS. MCRD, which implements mobile-based and network-assisted-based technologies, can automatically calculate and update its location. However, Mcrd using mobile-assisted-based and network-based technologies usually has communication capabilities that allow it to update its current position by receiving a location from the network

O: \ 87 \ 87685.DOC -14- 200407006. After updating its current position, any kind of position-aware processor on the MCRD will compare the current position with the trigger zones. If the current position falls within the range of at least one trigger zone, the checker on the MCRD will generate a trigger signal. To wake up the host system in sleep mode and notify the application. In another embodiment, the position coordinates are transmitted in the communication protocol header. For example, PicoRadio developed by the University of California, Berkeley, the address of a node in the PicoRadio network is defined as a ternary value group, which includes the position coordinate and the node type. And data types. This embodiment expands the position coordinates from the communication protocol headers of the data message transmitted by several nearby nodes. This embodiment can use an MCRD that implements the PicoRadio network interface to receive the coordinates of the nearby network interface and Calculate its current absolute position.

Proximity perception MCRD

FIG. 3 depicts a preferred embodiment of the present invention for sensing a proximity environment. This embodiment includes a host system 0120 and a proximity awareness MCRD 03 00. The MCRD 0300 uses the PCMCIA port connected to the system bus to connect to the host system 0120. The MCRD 0300 includes an IEEE 802.1 1b wireless communication interface (WCI) 03 (H, a checker 0302, an interface controller 0303, and a memory 0304. The WCI 0301 includes a radio frequency (RF) front end 0305, a base frequency Processor 0306, and a media access control (MAC) controller 0307. The RF front end 0305 receives the RF signal, down-converts it to a lower frequency analog signal, and passes it to the base frequency processor 0306. The base frequency processing The device 0306 demodulates the analog signal into a physical layer data frame, then decodes it and passes a MAC frame in the physical layer data frame to the MAC controller 0307. In order to distinguish all WCI 0. \ 87 \ 87685.DOC -15- 200407006 and control the wireless media access of WCI, each WCI will be given an identification code. The identification code is a MAC address in the MAC sublayer communication protocol. The format of the MAC frame includes A header field and other data fields. A MAC frame header can include one or more identifier blocks, such as receiver address, transmitter address, source address, destination address, or BSSID. The BSSID is the MAC address of an access point. The MAC controller 0307 will The MAC frame is decoded. If the destination address or receiver address is WCI 0301 or packet

For a group of addresses including WCI 0301, the data unit of the MAC frame is passed to other communication protocol layers. Due to the limited operating range, WCI 0301 can only receive data transmitted on wireless media by other WCI nearby. So 'the transmitter address of that MAC frame reveals the identification code of another wci nearby. The receiver address still implies that the other WCI specified by the receiver address is also close to the WCI 03, and the BSIId also implies a nearby access point. The MAc address fields in the MAC frame are the environment of which the environment sense application granularity 0108 is interested, and a trigger state of the environment refers to at least one MAC address of another WCI that the application wishes to detect. The child application 0108 on the host system 0120 receives a request to perform a job and a trigger condition from a user or other application. The trigger condition is other

Rules of existence. A simple existence rule may include another wCI (4 Bima ’s more complicated existence rules may be the identification of several other wos (such as the Bollinger equation, etc.). The i code of each WCI in the existence rule is one Trigger identification Λ, minus code. An identification code can be provided for the existence rule (with-Spear Shaw as "Back Beer Reading Η 2; Zhuang, ,, Ma"), such as a number, a work identification code, 1; the identification code, or the total 1 1M trigger identification code, used to inform the application 0108

O: \ 87 \ 87685.DOC -16- 200407006. The application program 0108 instructs the interface controller 0303 to store the existence rule in the memory 0304 via the bus. The MAC controller 0307 continuously or periodically receives the MAC frame, and

The MAC frame is decoded, and the checker 0302 receives one or more identification codes in a plurality of identification code fields of the MAC frame from the MAC controller 0307. The checker 0302 considers the WCI specified by the received identification code to exist, and evaluates the existence rule. If the existence of the triggering WCI or triggering identification code meets the requirements of a rule, the existence rule is triggered. Then if there is a triggered existence rule ', the checker outputs a signal. In another embodiment, the checker may record the last receiving time of a trigger identification code. If the last receiving time of the trigger identification code is within a period from now, the WCI specified by the trigger identification code is regarded as presence. The MCRD 0300 and the host system 0120 can enter the power saving mode independently. This power saving mode means stopping power supply or entering a low or inactive sleep mode. To reduce power consumption, the host system 0120 can enter power saving mode when there is no activity. Notifying the application

Before 0108, if the host system is in the power saving mode, the financial trigger signal can first wake up the king machine system 0120. The application 〇〇〇〇〇Child interruption. The server takes a trigger ID or a triggered existence rule (or its rule ID) and passes it to the application. In another embodiment, the “the interrupt service can only interrupt the application program” and the application program triggers the trigger identification code or the triggered existence rule (or its rule identification) by commanding the interface controller. code). Then, the application

O: \ 87 \ 87685.DOC -17- 200407006 identifier to evaluate the existence rules, and perform the work that exists rules that are evaluated as true or received from MCRD 0300. In order to detect more existence conditions, the checker 0302 can also schedule a timer to re-evaluate the existence rules. If the latest reception time is recorded and is longer than a certain period from now, it can be timely. No WCI detected. In another embodiment, WCI 0300 complies with the Bluetooth communication protocol. The trigger identification code is the Bluetooth device address (BD_ADDR) or its lower address part (LAP). The identification code of other nearby WCIs can be detected from the access code of each received packet, or from the BD-ADDR of the received FHS packet. These access codes include channel access code (C AC), device access code (DAC), and interrogation access code (IAC). The identification code found in C AC is the LAP of the master of piconet, and The identification code found in the DAC is the LAP of a piconet's controller. In other embodiments, the wireless communication interface may comply with other proprietary communication protocols or industrial communication protocols, such as Bluetooth, CDMA, GSM, GPRS, RFID, IrData, UWB, and the like. In another embodiment, the WCI 0300 further includes a TCP / IP offload engine (TOE) for processing the TCP / IP communication protocol stack in dedicated hardware. The trigger identification code is an IP address in the TCP / IP, which is very useful when the IP address is a static mobile IP address. In order to further reduce power consumption, in another embodiment, the MCRD 0300 or MCRD 0200 is powered off or entered into the power saving mode periodically, and a timer is woken up at a preset time to perform the environment receiving work. In some embodiments, the MCRD 0300 includes a way to help other systems discover the MCRD 0300 itself, such as broadcasting an identification code for the WCI 0300. O: \ 87 \ 87685.DOC -18-200407006 For example, the MAC controller 0307 can periodically send out a packet or frame containing its identification code (a MAC address) to expose its identification. Since other systems of the present invention can detect the identification code from the packet or frame, the packet or frame can be broadcast or assigned to any system. Users can of course choose to not expose the system for security or privacy considerations. The better way to expose the WCI 03G1's ID is by sending a packet or frame addressed to the WCI03G1 itself. In this way, the impact is reduced to other equivalents that are not concerned with this identifier. The transmitter itself can ignore messages that it sends out. In fact, 'most wireless front-ends (such as RF front-end 035) use the same group of antennas to transmit and receive signals, and are either in transmission mode or reception mode, so the receiver will naturally not hear the packet. . In another-implementation, it will release an identification code to others as needed. For example, user A wants to tell user B his identification number so that user B can find him later. User A ’s WCI can send out—special packets (such as Request-to-Send (RTS) packets in IEEE 802.1 1b). The packet address and receiver position are set to the mac address of eight out of ten. Two users can press the button or issue an instruction at the same time to release and obtain the identification code. Before and after user B presses the button, user B = WCI receives the same transmitter address and receiver position. Address of the packet. The packet received by user B's WCI is most likely a packet sent using wci of test A, so the WCI identification code of user A reaches user B. The user can change the time delay tolerance between the user B button and the receipt of the packet. To discover nearby numbers In another embodiment, build a wireless network server O: \ 87 \ 87685.DOC -19- 200407006… and store b in its memory. The temple server can broadcast messages periodically (for example, every other minute) to indicate its existence. The system of the embodiment of the present invention may query the server to explore other systems nearby. When the server receives the query, 'The server explores whether the system exists and responds to the nearby system list ... The system of this embodiment decodes the received address list' and compares it with these trigger addresses. Compared to car pay. If the address list received by the user intersects with the set of triggering addresses in the memory of the network interface, that is, the received address list contains the address address__trigger bit & The network interface is referred to the wake-up attack system. If the parent set, the network interface card is dormant, but the network interface must be periodically awakened to update its existence to the server. Otherwise, if the κ system is not updated for a period of time, the server can remove the system from its table. Removed from the column. Using Multiple Action Environments Figure 4 depicts an embodiment of the present invention, which includes a dual-mode WCI 401, which implements multiple communication protocols (IEEE 802.1 17 and Bluetooth). The Bluetooth-equipped printer 0402 and the vending machine 04〇3 are both in a static position within the operating range of the IEEE 8102.1b access point 0404, and the access point 0404 is also in a static position. Since the operating range of the Bluetooth communication protocol is shorter than that of 802.1 1b, the identification codes of the devices 0402 and 0403 can be activated only when the identification code of the access point 0404 exists. Therefore, the existence of the trigger ID of the access point 044 will enable the trigger IDs of the devices 042 and 0403, otherwise the trigger IDs of the devices 0402 and 0403 will be disabled. Therefore, in the present invention, a trigger state can be enabled or disabled by another trigger state. In another embodiment, an MCRD may include a GPS receiver or a GSM transceiver. Therefore, the environment received by multiple MCRDs constitutes a more complex O: \ 87 \ 87685.DOC -20- 200407006 environment. Flowchart of the present invention FIG. 5 illustrates a power saving method of an action sensing system according to some embodiments of the present invention. In stage ㈣〇, select the environment to be used. The dynamic environment can be a location environment, a proximity environment, or both. For the environment, a reference positioning system (such as a GPS positioning system) will be selected; for the proximity environment, the communication protocol (such as ^ 802 ″ lg) and the various environments of the waiting environment will be selected. (Hereinafter referred to as "sense · ㈣"). The sensor WCI is preferably moved together with the host system. In the phase reading, an environment-aware application 0108 on the host system receives the request and the trigger condition. The job includes one or more actions, such as instructing to use a known password to log on to the network, pulling email, and using a text-to-speech application to read email. The triggering condition defines a triggering state in the action environment, and if the current state of the action environment is in or belongs to the triggering state domain, the job will be performed. The trigger status in this position environment is the-area in the reference positioning system (hereinafter referred to as the "trigger area"). The triggering state in this proximity environment is the existence rule of the sensor or WCI (or “triggering WCI”) other than the sensor WCI. The identification of each trigger we in the existence rule is the trigger code of the horse. If it is received within a certain period of time, the identification code of a WCI in the existence rule is the existence of the WCI, otherwise it is not. In 1¾ & 0502, the trigger condition is stored in a memory. For the location environment, the trigger area is stored in the memory. For a proximity environment, the existence rule is stored in the memory. Complex existence

O: \ 87 \ 87685.DOC -21-200407006 The rules can still be decomposed into simple existence rules. For example, there is only one trigger identification code in each small rule, and these simple rules (that is, multiple trigger identification codes) are stored. I have thoughts. The trigger condition can still be associated with an identification code (hereinafter referred to as "callback identification code" and stored in the memory. The callback identification code can be a number, a rule identification code, a work identification code, Or trigger the identification code itself. In stage 0503, if the host system has extremely low or no activity, the child king system is placed in a power saving mode.
