Description

1357236 发明, the invention description: [Technical Field] The present invention relates to a mobile computer system, and more particularly to a system and a method for reducing the power consumption of an action-aware computer system. [Prior Art]

Many computers (4) are designed to target the mobile consumer market, such as the use of Palm 0S or Microsoft P〇cket pc operating systems, and personal digital assistants (PDAs). These actions L are used for a variety of applications, such as itineraries, mentoring, to-do list warning applications, and so on. Most commercially available applications only sense time, for example, the itinerary application will notify the user when the appointment is scheduled. However, most of the affairs in life occur in response to certain environmental conditions. We use the term “environment” to describe these situations. There are many other things in real life, such as temperature, lighting conditions, "in the conference room" and so on. The most important environment associated with a mobile application is the m〇bnity context, which is usually classified into an absolute location and a relative location, hereinafter referred to as a location context and a proximity environment (pr〇ximity context). Applications that detect certain environmental changes or exist and respond to the environment are called context aware applications, and environmentally aware applications that sense the action environment should be called mobility aware. An action-aware application that senses absolute position is called a location-aware application, and an action-awareness that senses relative position is called a proximity-aware (pr〇ximity aware application). Many studies on action-aware applications have been done. . Some applications sense the absolute position by using radio waves to determine

O:\87\87685.DOC 1357236 大部分 For most of the well-known applications, navigation systems using positioning systems (such as Global Positioning System '"light (GPS), etc.) to provide local maps and driving directions are described in US Patent No. 6,177,905 a position-triggered reminder for the mobile user that uses a global positioning system (GPS) to locate the user's geographic location, and then when the user enters the coordinate and radius information provided by the user k In the defined area, an alert message is requested. This system requires a positioning system (such as GPS) to be used in conjunction with a personal digital assistant (PDA), thereby increasing manufacturing costs and battery power consumption. Almost all of these positioning systems are in the suburbs. In the room @ or tall buildings, the use of the limit or the useless, some applications of the invention of the exclusive radio wave transceiver to help determine the position of the mobile station, such as AT & T - System System. · Some applications perceive relative position ' That is, the perception of the presence of other users (or indeed their mobile devices) nearby. These context-aware applications are called proximity-aware applications. Each proximity-aware application uses a disc〇very method to discover each other in the vicinity. "Some applications are equipped with a dedicated radio wave transceiver to periodically broadcast a device identification code or a user identification code. Other devices in the vicinity may Detect its presence, such as the Pr〇xy U-Fly system of the Victorian institution in Sweden. Some applications rely on wireless network communication (such as 8〇2Ub, etc.) to establish a connection, such as the GUIDE system of Lancaster University, UK. The wireless network architecture provides location information to the mobile unit. The Proem system of the University of Oregon is a profiling proximity aware application that defines an existing communication protocol (such as TCP/IP, UDP 4 HTTP). Application layer communication protocol. After establishing the (four) connection of the special network H system, the Mm system

O:\87\87685.DOC 1357236 can discover each other. After establishing the network connection, the presence manager in the pr〇em system will announce its existence and will explore the nearby peers. «However, the establishment of a network data connection must be authenticated by a higher network communication, and it is not convenient to use. If the authentication procedure is relaxed, security protection will occur. Each type of environment has many different values or states (hereinafter referred to as "environmental states"), for example, temperature is an environmental type, and 76 degrees c is a state of the environment, and for a proximity environment, "before "An environment is sorrowful, and "not nearby" is another state. The entire space of a type environment (hereafter referred to as "environment space") is a combination of all possible states in that type of environment. Since the environment is dynamic, environment-aware applications must monitor their environment to provide timely responses. The system used by the pre-m technology must always be powered. However, because the environment-aware application only senses and responds to a certain: special state (hereinafter referred to as "trigger state"), the application fee is mostly spent Monitor the environment, not the response environment. Most of the 3 per-period perceptions should be applied to the swaying device with limited power resources (such as batteries). If the power consumption is not taken into account, the environment-aware application will become inconsistent. The existing environmental perception (4) has not solved this problem. The company has used a variety of power management strategies to reduce computer and power consumption to protect our environment. These strategies control the circuit clock, the stone off the computer chip - the power of the circuit block 'reducing the power consumption of components in the computer (such as: disc)' to shut down the entire computer has been applied in many different ways to only apply (in hardware, in a moving body, or in a soft body). The power management strategy at the computer system level reduces the power consumption of the computer system or part of the system components when the computer is not used: \87\87685 D〇c 1357236 system, and then the computer is usually called :: Wake up, the power management strategy has different wake-ups to the Wuji user to schedule a job to shut down the computer at night. And in the early computer 'this method is implemented - the timer or clock mechanism comes to the temple and shuts down and wakes up the computer system at a specific time. The one used to manage the computer's power in the network (Μ( (Wake_0n_LAN; job). The network interface with the online wake-up function in other brain systems that stop supplying power to the computer system still consumes micro! Power. The computer system sends a special format packet to the network interface. The special format packet includes a network media access control concealed address on both sides of the receiving network to be woken up, but the wakeup device is The packet transmitter network interface begins. The prior art of the shoulder-power method is not sufficient for the action-aware application. For example, 'US Patent No. 6,1, 77,905 must have its host system and sensor: keep the execution towel (aHve) ) can continue to monitor the current location, and trigger the user's work when the target location falls within the pre-selected region. The presence of the oem system administrator (presence café (4)) depends on the special network (adhQene_k) The data link and the network layer, and the network layer pass on the system, so the pr_ system must also keep the host system and the network interface enabled. All of the application's advanced technologies keep the system enabled while monitoring the environment. However, the application only needs to consider some environmental conditions.

When the processing unit is turned off, the MCRD is still being executed and consumes very little from a power supply (such as a battery). I power to perform environmental detection. Before the MCRD finds a coincident trigger condition to signal the processing unit, if the processing unit is in power save mode A, the chirp signal will be at the level of the power supply supply at the processing unit.

The wireless communication interface receives the wireless media messages continuously or periodically and decodes the identification code fields in the message. The checker receives the one or more identification codes decoded by the message and treats the WCIs specified by the received identification code as being present. The checker then evaluates the existence rules and the checker outputs a signal if there is a condition that exists to comply with the current existence of the WCI.

Location Aware MCRD Figure 2 depicts a preferred embodiment of the present invention for sensing a location environment. This embodiment includes a host system and a location aware MCRD. The mcrd is connected to the host system via a connection, an I/O bus. The MCRD 0200 includes a GPS signal processor 0201, an inspector 2, an interface controller 0203', and a memory 0204. The signal processor receives signals from a plurality of satellites and determines their position by triangulation. A position is usually composed of longitude, latitude and height. An environment aware application 0108 on the host system receives one or more jobs and a trigger zone for each job from the user or other application. The application 〇1 〇8 then instructs the interface controller 〇2〇3 to store the trigger regions in the memory 0204 via the bus bar. The signal processor 〇2〇1 is continuously or periodically calculated and Update your current location. The checker 〇2〇2 then compares the current location with the trigger zones in the memory 0204. When the current location belongs to any of the trigger zones in the memory 0204, the checker 〇2〇2 generates a trigger t number to notify the application 〇1〇8. The MCRD 0200 and the host system 0120 can enter the power saving mode independently. This power saving mode means to stop powering or enter a sleep mode with low or no activity. To reduce power consumption, the host system 0120 can enter a power save mode when there is no activity. Before notifying the application private 0108, if the host system is in the power saving mode, the trigger signal can wake up the host system first. The application 〇 1 〇 8 can execute the interrupt service when the host system 0120 mad book an interrupt service 'host system 〇丨 2 〇 receives the trigger signal ^ the interrupt service captures the triggered trigger area,

O:\87\87685.DOC -13· 1357236 is passed to the application 〇108. In another embodiment, the interrupt service can retrieve the current location and the application can find the trigger zone triggered by itself. The application 0108, upon receiving the triggered trigger zone, performs the work associated with the triggered trigger zone. With interrupt service, the application 0108 can respond quickly to environmental changes without introducing unnecessary activity to monitor the environment. The trigger zone information may further include an identification code (e.g., a number) provided by the context aware application, and the interrupt service may only notify the environment aware application of one or more identification codes of the triggered trigger zone. In the example of Figure 2, the MCRD is used as a Gps receiver for the positioning device. However, any positioning device can be used as the MCRD for detecting the location environment in the present invention. The MCRD can implement any positioning technique known to those skilled in the art. Positioning technologies include mobile-based, mobile-based, network-based, and network-assisted positioning technologies. In mobile-based technology, the system performs location calculations autonomously, such as the Global Positioning System (GPS); in mobile-assisted technology, the system performs some auxiliary actions for positioning, while the network (or network) The server on the road performs actual position calculations, such as enhanced observation time difference (E-OTD). In network-based technology, the network performs actual location calculations, such as time of arrival (TOA); in network-assisted 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 technology, can calculate and update its location spontaneously. However, MCRDs based on mobile phone-assisted and network-based technologies typically have communication capabilities to update their current position by receiving locations from the network: O:\87\87685.DOC -14- 1357236 Set. After updating its current location, the processor on any kind of location-aware MCRD will compare the current location with the trigger zones. If the current location belongs to 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 yet another embodiment, the location coordinates are transmitted in a communication protocol header, such as PicoRadio developed by the University of California, Berkeley. The address of a node in the PicoRadio network is defined as a ternary value group including location coordinates, node types. And the type of information. In this embodiment, the location coordinates are extracted from the communication protocol header of the data frame transmitted by several nearby nodes. In this embodiment, an MCRD implemented as a PicoRadio network interface can be used to receive coordinates of the nearby network interface. And calculate its current absolute position.

Proximity perception MCRD

Figure 3 depicts a preferred embodiment of the invention for sensing a proximity environment. This embodiment includes a host system 0120 and a proximity aware MCRD 0300. The MCRD 0300 is connected to the host system 0120 using a PCMCIA port connected to the system bus. The MCRD 0300 includes an IEEE φ 802.1 1b wireless communication interface (WCI) 03 (Η, an inspector 0302, an interface controller 0303, and a memory 0304. The WCI 0301 includes a radio frequency (RF) front end 0305, a base The frequency processor 0306, and a media access control (MAC) controller 0307. The RF front end 0305 receives the RF signal, downconverts it to a lower frequency analog signal, and passes it to the baseband processor 0306. The fundamental frequency The processor 0306 demodulates the analog signal into a physical layer data frame, and then decodes and transmits a MAC frame in the physical layer data frame to the MAC controller 0307. To distinguish all WCI O: \87 \87685.DOC -15- 1357236 and controlling the wireless media access rights of the WCI, each WCI is given an identification code. The identification code is a MAC address in the MAC sublayer communication protocol. The format of the MAC frame Including a header block and other data block, a MAC frame header may include one or more identifier fields, such as a receiver address, a transmitter address, a source address, a target address, or a BSSID. Etc. The BSSID is the MAC address of an access point. The MAC controller 〇 3 7 Decoding the MAC frame. If the target address or the receiver address is addressed to WCI 0301 or a group of addresses including WCI 0301, the data frame of the MAC frame is transmitted to other communication protocol layers. Due to the limited operating range, WCI 0301 can only receive data transmitted by other WCIs on the wireless medium in the vicinity. Therefore, the transmitter address of the MAC frame reveals another wci identification code in the vicinity. The receiver address is still Implying that another WCI specified by the receiver address is also close to the WCT 0301, the BSSID also implies an access point in the vicinity. The MAC address fields of the MAC frame are of interest to the context aware application 0108. Environment, and a trigger state of the environment refers to at least one MAC address of other WCIs that the application wishes to detect. The application 〇1〇8 on the host system 0120 receives execution work from the user or other application. The trigger condition is the existence rule of other MCIs. A simple existence rule may include another identifier. The more complicated existence rule may be the identifier of several other wcj The equation (such as the Boolean equation, etc.), the identification code of each WCI in the existence rule is a trigger identification code. The presence rule can be provided with an identification code (hereinafter referred to as a "callback identification code"), for example, a number, a a work identification code, a rule identification code, or the trigger identification code for informing the application 0108 to touch

O:\87\87685.DOC I3572’36 The rules of existence. The application 0108 instructs the interface controller 0303 to store the presence rule in the memory 〇3〇4 via the bus. The MAC controller 0307 receives the MAC frame continuously or periodically, and decodes the mac frame, and the checker 0302 receives the number of identifiers of the MAC frame from the MAC controller 〇3〇7. One or more identifiers in . The checker 0302 treats the WCI specified by the received identification code as being present and evaluates the existence rule. The presence rule is triggered if the presence of the triggering WCI or the trigger identification code meets the requirements of a rule. The checker then outputs a signal if there is a triggered presence rule'. In another embodiment, the checker can record the last receiving time of the green one trigger identification code. If the last receiving time of the trigger identification code is within a certain period from now, the WCI is specified by the trigger identification code. The same exists. The MCRD 0300 and the host system 0120 can enter the power saving mode independently. This power saving mode means to stop powering or enter a sleep mode with low or no activity. To reduce power consumption, the host system 012 0 can enter a power save mode when the 揉 is active. Before notifying the application 0108, the trigger signal may wake up to host system 0120 if the host system is in power save mode. The application 〇 1 〇 8 can register an interrupt service in the host system. The host system 〇 120 executes the interrupt service when the output signal is received. The interrupt service retrieves the triggered trigger identifier or the triggered presence rule (or its rule identifier) and passes it to the application 0108. In another embodiment, the interrupt service may only interrupt the application 0108, and the application triggers the triggered trigger identification code or triggered from the MCRD 0300 by commanding the interface controller 〇3〇3. There is a rule (or its rule identifier). The application 0108 then evaluates the presence rule with the received trigger ΟΛ8 7\876S5.DOC • 17· 1357236 identification code and performs the work of the presence rule evaluation as true or the presence rule received from MCRD 0300. In order to detect more existing extrusions, the inspector 0302 can still schedule a timer to re-evaluate the presence rule 'if the latest reception time is recorded and is longer than some time from now.' Can detect WCI that does not appear in time. In another embodiment, WCI 0300 conforms to the Bluetooth communication protocol. The trigger identification code is the Bluetooth device address (BD_ADDR) or its lower address portion (LAP). The identification codes of other nearby WCIs can be detected from the access code of each received packet or from the BD_ADDR of the received packet. The % access codes include a channel access code (CAC), a device access code (DAC), and a ^^ gate access code (IAC). The identification code found in the CAC is the LAP of the main # of the piconet. The identification code found in the DAC is the LAP of the piconet's controlled person. In other embodiments, the wireless communication interface may conform to other special communication protocols or industrial communication protocols, such as Bluetooth, CDMA, gSm, GPRS, RFID, IrData, UWB, etc. In another embodiment, the WCI 0300 is still Includes a TCP/IP Offload Engine (TOE) for handling TCP/IP protocol stacks in proprietary hardware. The trigger identifier is an IP address in the TCP/IP for the IP address system. Very useful for a static mobile IP address. In order to further reduce the power consumption, in another embodiment, the MCRD 0300 or the MCRD 0200 is powered off or enters the power saving mode, and is awakened by a timer at a preset time to perform the environment receiving work. In some embodiments, MCRD 0300 includes means to assist other systems in discovering MCRD 0300 itself, such as the identification of WCI 0300.

The system of embodiments of the present invention can query the server to explore other nearby systems. When the feeder receives the query, the server explores the presence of the system and returns a list of nearby systems. The system of the present embodiment decodes the received address list' and compares it to the trigger addresses. If the received address list is intersected with the set of trigger addresses in the memory of the network interface, that is, the address list received has a location of a trigger address, the network interface That is to wake up the system. If there is no intersection, the network interface card is dormant, but the network interface must wake up periodically to update its presence to the server. Otherwise, if the system is not updated for a period of time, the server can list the system from its list. Removed. Using Multiple Action Environments FIG. 4 depicts an embodiment of the present invention, which includes

802.1 1b A static location within the operating range of point 0404, access point 0404 is also in a static location. Since the operating range of the Bluetooth communication protocol is shorter than IEEE 802.1 lb, the identification codes of the devices 0402 and 0403 can be enabled only when the identification code of the access point 0404 exists. Therefore, the presence of the trigger identification code of access point 0404 enables the trigger identification codes of devices 0402 and 〇4〇g; otherwise the trigger identification codes of devices 0402 and 0403 are disabled. Thus, in the present invention, a trigger state β can be enabled or disabled by another trigger state. In another embodiment, an MCRD can include a GpS receiver or a GSM transceiver.

The sensor WCI preferably moves with the host system: in the stage 'received by the context aware application 0 (10) on the host system - the request to perform the work and its trigger condition. The job includes one or more actions, such as indicating the use of a known password to log into the network, accessing e-mail, and using a text-to-speech application to read e-mail. The trigger condition defines a trigger state in the action environment, and if the current state in the action environment is equal to or belongs to the trigger state range, the work will be performed. The trigger state of the location environment command is the - region (hereinafter referred to as "trigger zone") in the reference positioning system. The trigger state in the proximity environment is a rule of existence other than the sensor's abundance or a plurality of WCIs (hereinafter referred to as "trigger WCI"). The _ code system-trigger identification code of each triggering wci in the existence rule, if a certain wcr identification code exists in the rule within a certain period of time, the WCI system exists 'otherwise not. In stage 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 1357236 Rules can be broken down into simple rules of existence. For example, there is only one trigger identification code in each small rule, and these simple rules (ie, multiple trigger identification codes) are stored. In this memory. The trigger condition may be associated with an identification code (hereinafter referred to as a "callback identification code" and stored in the memory. The callback identification code may be a number, a rule identification code, a job identification code, Or triggering the identification code itself. In stage 0503, if the host system has very low or no activity, the king system is placed in a power saving mode. The power saving mode means that the system is placed in a sleep power state, Suspend the power state, or be familiar with any power saving state known to those skilled in the art. There are many conventional ways to place the system in a power saving mode, which can be manually switched by the user or automatically entered by the operating system. In state 0504, the receiving station The current state of the selected action environment. For the location environment, the current state is a location in the reference positioning system received by a positioning receiver (such as Gps, etc.). For the proximity environment, the current state is currently The detected identification codes are decoded from the messages received and processed by the sensing benefit WCI. For example, the identification codes are received in an IEEE 802.1 1b MAC frame. The address field and the transmitter address field. The environment receiving program is known to those skilled in the art. For example, the GPS signal processor 0201 receives signals from a plurality of satellites and performs triangulation to determine the current Location ^ For example, IEEE 802.11 WCI 0301 decodes the message and determines that the message is assigned to wci 0301. The message assigned to WCI 0301 includes broadcast messages (such as Address Resolution Protocol (ARP) requests and WOL magic packets) and Messages addressed directly to WCI 0301.
