The device transmits a plurality of data. [Embodiment] The first diagram is a schematic flowchart of a method 100 for controlling access to a communication medium according to the present invention. By way of example and not limitation, the party 100 is implemented in a first device (such as a remote device with energy saving features) in a communication network. In the discussion of Figure 1 below, the instructions for implementing the method 100 are referred to as "first devices". Sigh In step 110 of method 100, wait for an event to exit the sleep state of the power saving mode. This event can be a direct instruction from a user, which requires a network device working in the energy-saving mode sleep state to exit its energy-saving mode sleep state. This event can also be the periodic expiration of a timer. This event can usually also be any event that can cause the device to at least temporarily exit its power-saving mode. In step 120 of method 100, the first device exits its power saving mode. The exemplary method 100 described in the first figure works in conjunction with a network with energy-saving features, because the energy-saving environment is a convenient environment that can embody different features of the present invention. Therefore, the scope of the present invention should not be limited to devices with energy-saving features or networks containing energy-saving features. In step 130 of method 100, the first device obtains access and control of the network communication medium. These accesses and controls can be access and control of a single communication channel, such as an FDM frequency, a TDMA time slot, a frequency hopping sequence, or a CDMA code. Such access and control may also be access and control of a plurality of such communication channels. This access and control can also be access and control of all communication channels in a communication medium. The acquisition method includes access and control of at least a part of the shared communication medium obtained based on a competitive media access agreement. For example, the first device may control multiple network access media based on a carrier sense using a collision avoidance (CSMA / CA) protocol. In the wired network, the first device can also control the multiple access media using carrier sensing using the collision detection (csma / cd) protocol. Therefore, the scope of the present invention should not be limited to, ridiculed or set of agreements. Similarly, the scope of the present invention should not be limited to a specific communication medium or a group of communication media. In the network step i4G, the first device sends the communication media to the second one. If there is no information to transfer to the second network device! Step 140 can be skipped. This information can be data or control information, including a single package or multiple packages. This kind of information is transmitted to the receiver and the confirmation instruction packet is received. Therefore, the response should be limited to the format or type of status information. The scope of the invention should not be limited to the special communication mechanism. ▲ Need to be careful ’In step 14G, security measures of typical media access can be used to maintain the communication rewards of the communication network by force, time, and time. For example, until device multiple information needs to be transmitted, step 14G will not enable the first device to control the communication medium without the need for any communication. This undetected control can have a deleterious effect on the drive at certain times. As a result, the network can limit the time it takes for the equipment to control the rail ship or part of it. …, In step 15G of the law, the first device will control the communication medium. After receiving this kind of ship control from the first device, 7 such as the acquisition of other communication equipment with the communication medium as an example rather than a restriction 'if the first device to the second device in step 0, (for example, the network connection (Entry point) to transmit information, the first device sends the secret control to the second device or other network devices at step 150. The second device can transmit the control of the communication medium to the first device in different ways. -Sorrow. For example, the first shop can send a clear notice to the second device = 13 200527192 control of the communication media. Moreover, this notification can be completed to the first or second network. The data packet transmitted by the road device includes control information and data information. Therefore, the present invention 1 should not be limited to the specific mechanism of riding and driving. In an exemplary energy-saving environment,- The remote energy-saving device can notify the transfer control micro-body and access point of miscellaneous facts. And prepare! Can be controlled by til 'section _ continued to send downlink data (dcls The tream ^ entry point can distinguish energy-saving devices in its network. Different interaction methods are not accepted. The remote point is not controlled. That is, the entry point can be selected in step 160 of the green 100 to receive the second device. Information = -The device receives control of the communication ship in step 150. When narrow, in the case that there is no information to be transmitted, you can skip "^ ○ ^ ^ Poor material package shape ^, which contains data and / or The control device can transfer one or more decentralized data packets to the second device while transferring control to the communication media. The port can also be prepared by wheels, which can be used by various devices to control specific devices. Controllable communication media time = When this is combined with the media pure control according to the present invention, the second limit and the second device controllable communication media are combined in an exemplary energy-saving network environment. The second device can When the energy-saving 200527192 device is in the sleep mode of the energy-saving mode, the network access point can buffer the business volume sent to the energy-saving device. Generally, the second device can be any business-oriented traffic to the first The network entity transmitted by the device. In the case that the second device has no information to transmit from the first device, the process of the method 100 can skip step 1). Note that the scope of the present invention should not be limited to receiving specific types of information, or Receive information of a specific type of network entity. In step 170 of method 100, the user is notified of the most recently transmitted information. For example, the remote device may notify the remote device user to inform it that it has received a mesh update Information — facts. The user can control the existence, characteristics, and timing of such notifications. For example, the user can specify the device without notifying the user. The user can also specify the device to know the user only about the specific type of information. Therefore, the present invention The scope should not be limited to any feature of such notice. At the step of method 100, step 180, the first device re-enters the energy-saving mode. In the -exemplary energy-saving environment, after exchanging with the network access point ^, the -device can re-enter the energy-saving mode ^^ = state. As mentioned above, the energy-saving network is prepared or a network including such equipment. The second diagram is used to control the intent of the one-use method according to the present invention. In the case of accessing and using the map ^ = ^, which can be the access point Φ in the communication network, the device for implementing the method 200 is called in step 21 of the method 200 below. Come: Prepare. Access to communication media can be obtained by implementing a media access agreement. Step 15 200527192 sub-steps. Depending on the specific communication situation, the first device may or may not follow these sub-steps. Step 210 includes step 212, which will accept the initial data packet from the second device. Step 210 may also include step 214, which may receive additional information packets from the second device. In an example scenario, when the second device has more information to transmit to the first device, and the information is larger than can be reasonably packaged in a single packet, the first device will perform step 214. The size of the system package can limit the size of the package. Step 210 also includes a sub-step 216, which receives from the second device an indication that the first device has implemented control of the communication medium. This instruction is a clear indication

Investment II; ^ -ΐΐ246, through communication media Passed to the second device but removed the sleeve -1, and finally followed the transmission. The method previously discussed for compensation data exchange is only used as an example. The method can use various alternatives. Therefore, the present invention should not Limited to specific resources': When the first device has retrieved the information to be sent to the second device = 0:; = Γ: =: transmits the retrieved information, while the institute 3Γ controls the communication Gu, and transmits it through the communication media. 〇LtT, Therefore, the scope of the present invention should not be limited to a specific information, data packet format, or lean packet flow format.

This release can be used by the specific communication media used by the rules of the present invention. The communication of the butterfly network of the present invention can be accessed in accordance with various communications and other places. The delay is limited to ensure that other network equipment can be leveled. According to the first exemplary standard implemented between two devices in Japan, this example has been provided. This example should not be limited to the characteristics and implementation methods of IEEE 802.11 18 200527192. The top line of Poor News Exchange 300 is marked "qsta". It usually refers to the service base station quality of ieee ^ A_t1 standard. In this example, QSTA can be regarded as the first network device with the "b" feature. Information exchange is marked on the bottom line of 300. It usually refers to the quality of the service access point in the IEEE 8021 standard. In this example, QAP can be considered as a second network device. Second, before the exemplary information exchange 300 described above, QSTA will obtain the communication, For example, QSTA may obtain access to communication media based on competing media access protocols, such as the CSMA / CA protocol.

The third information 330 may be a > data resource with no multiple flags set. The non-disabled multi-identity may indicate to the QAP that the QSTA has no more data to transmit to the QAP. The number of unset flags may also indicate that control of the communication media has been passed from QSTA to QAP. As discussed above, QAP treats energy-efficient and non-energy-efficient equipment differently. For example, if QAP determines that QSTA is a non-energy-saving device, QAP may only confirm the reception of the third information 330, and then terminate communication with QSTA, and then release the communication medium. Conversely, if QAP determines that QSTA is an energy-saving device, Then QAP will receive control of the communication media from QSTA to send 19 200527192 information traffic back to QSTA. At this time, the QAp of the exemplary information exchange 300 will implement its control over communication media. QAP responds by sending a fourth message 34o to QSTA. The fourth information 340 may be Qj material information, which includes instructions to send to qsta as material and confirm that the third information 330 has been received. Then, the exemplary information exchange 300 will send a fifth from QSTA to QAp for the flood 350 'which can be used to confirm receipt of the fourth information 34. Then, the information exchange, 300, will send sixth information from QAP to qSTA, this information may be additional information to be sent to QSL \. Then, the information exchange 300 will reach Q-Seventh Poor News 370 from QSTA, and the information includes a confirmation that the sixth information 360 has been received. One indication = the sexual information exchange 300 can continue to exchange between the Qsm and QAp, and the parent exchanges Dfl until all the information that QAp will transmit to qsta is sent. The exchange of information may be stopped for reasons such as the time limit for media access being exceeded, or other considerations related to fair access, or the volume of services collected by QSTA in China or China. … The fourth figure is a schematic diagram of the second example = rf / 00 implemented in the two network system according to the present invention. This exemplary information exchange with the exemplary information exchange described in the third figure is also provided in the 1EEE⑼2.11 standard. However, the scope of the present invention should not be limited to the characteristics and implementation methods of IEEE 802.11. Q400 is marked with "QSTA" in the top row. It usually refers to the quality of the base station. In this example, QSTA can be thought of as having "olp" Gandi: network equipment. The bottom line of the information exchange 400 is marked too-usually refers to the quality of the service access point of the IEEE 802.n standard. In this context, QAP can be considered as a second network device. % Before the media information exchange is 400, QSTA will gain control and control over communication. For example, QSTA may follow the Competitive Media Access 20 200527192 agreement to gain access to general media, such as the CSMA / CA agreement. When the negative (or negative material package) parent exchange 400 starts, the first information 410 is sent from qsta to QAP. The first information 41 may be Q-data information with no more flag set. In the case of energy saving, the first information 410 may indicate to QAP that QSTA is not currently in the sleep mode of the energy saving mode, and is preparing to receive from QAP the traffic that QAP caches when QSTA is in the sleep mode of the energy saving mode. The number of unset flags may also indicate the transfer of control of the communication media from QSTA to QAP. As discussed above, QAP treats energy-efficient and non-energy-efficient equipment differently. For example, if QAP determines that QSTA is a non-energy-saving device, QAp can only confirm the reception of the third information 410, and then terminate the communication with qsta 'to release the communication medium. Conversely, if QAP determines that QSTA is an energy-saving device, QAP can receive control of the communication media from QSTA to send information traffic from QAp back to QSTA. At this time, the QAP of the exemplary information exchange 400 will control the communication media. After a frame interval (SIFS), the information exchange 400 sends the second information 420 from the QAP to the QSTA. The second information 420 includes an acknowledgement indication (ACK) for indicating to the QSTA that the QAP has received the first information 41. In addition, the second information 420 includes an empty data frame to indicate to the qSTA that there is a buffered information service in QAP. The amount is transmitted to QSTA, but QAP needs extra time to get information from the buffer. This empty data frame allows QAP to maintain control of the communication media (such as the communication media control achieved by a contention-based media access control protocol) when qAP is acquiring the information traffic to be sent to qSTA. The exemplary information exchange 400 then sends third information 430 from QSTA to QAP. The third information 430 includes a confirmation indication that the QSTA has received the second information 420. 200527192 The information exchange 400 sends fourth information 440 from QAP to QSTA. The information includes that QAP retrieves the information to be sent to qsta from a buffer. Then, the information exchange 400 sends a fifth message 45 packets g from the QSTA to the QAP-a confirmation instruction that the fourth information 440 has been received. The information exchange 400 then sends a sixth message 46 from the QAP to the QSTA, which information includes the QAP retrieving from a buffer additional information to be sent to the qSTA. Then, the information exchange 400 sends the seventh information 470 from the QSTA to the QAP, which includes a confirmation indication that the sixth information 460 has been received.
示例性資訊交換400可以繼續在qSTA& QAp之間進行 以實現資§fl父換，直到QAP全部發送了要傳輸給qSTA之資 訊。另，QSTA及QAP之間可能因媒體存取時限之超出，或 其他形式之媒體存取控制機制，或與公平存取有關之其他考 慮，或者爲保證網路中QSTA所收集之服務質量等原因而停止 之資訊交換400。Exemplary information exchange 400 may continue to be performed between qSTA & QAp to implement the parent exchange, until the QAP has all sent information to be transmitted to qSTA. In addition, QSTA and QAP may be due to the time limit of media access, or other forms of media access control mechanisms, or other considerations related to fair access, or to ensure the quality of service collected by QSTA on the network. And stopped the information exchange 400.

For example, the media access module 522 uses any of various communication media access protocols and uses the transceiver module 515 to obtain access and control of the communication media. By way of example and not limitation, the media access module 522 may obtain control of the network communication media based on a carrier sense multiple access with a collision avoidance (CSMA / CA) protocol. In addition, the media access module 522 can obtain access and control of the communication media according to an aloha or CSMA / CD protocol. Therefore, the scope of the present invention should not be limited to access agreements for specific media. The MAC module 520 further includes a communication media control transmission module 521. After 23 200527192 the media access board group 522 has obtained access to and control of the media of §fl, the control transfer module 521 can transfer the control of the communication media to another network device. The network device may include a second network device ("second device") through the second communication module 540. After the second device receives control of the communication medium from the first device, it may Use the communication medium without performing various media access activities, such as competing with other network devices for access and control of communication media. The MAC module 520 can also provide the first device with a sleep state function for entering and exiting the energy saving mode. Various network devices transmit communication information. Then, other network devices can use this information to manage their processing of and communication with the first device. # It should be noted that the MAC module 520 is usually integrated There are various security measures related to media access, for example, a timeout function that can ensure that all network devices have fair access to the communication media. Therefore, the MAC module 520 includes various measures to ensure that the first device does not The communication medium has been controlled for an appropriate period of time. The control transmission module 521 can transmit control of the communication medium to another network device in different ways. For example, control transmission The module 521 can use the transceiver module 515 to transmit a clear message to other devices to transfer the control of the communication medium to other devices. In addition, the control transmission module 521 can use the transceiver module to transmit an empty data to another device. Frame to indicate that the first device no longer uses the read-through communication medium, and other devices can take over control of the communication medium. The first communication module 520 also includes a MAC module 520, a transceiver module H5, and an energy-saving module 5 〇5 connected data transmission module 53. After the media access module ^ 520 gains access to and control of the communication medium, the data transmission module 530 can transmit to another network device through the transceiver module 515 For example, in the system 500 shown in FIG. 5, the data transmission module 53 can communicate with the second device using the transceiver module $ 15. The data transmission module 530 can use the transceiver module 515 to transmit to the second device. A single data packet or data packet stream. The data transmission module 530 can also perform various data receiving functions. For example, when 24 200527192 controls the communication media from the first device to the second device, the data transmission module 530 can use the transceiver module 515 to receive the information transmitted from the second device currently controlling the communication medium to the first device. The information can be in the form of a single asset or a packet stream. ^ Moreover, when the first device and the first device At the end of the communication between the two devices, the data transmission f group 53f can communicate with the energy saving module 505 to give an instruction to the energy saving module 505, so that the energy saving module 505 decides whether to put the first device into the sleep state of the energy saving mode .

Fan Xingcai should be limited to each user's intermediary group, its function or details to see that the second communication module 540 is connected to the two 544 through a wired LAN network. . The second communication module and group 540 can be used. The scope of the present invention should not be limited to the characteristics of network equipment. Therefore, the scope of the present invention should not be limited to the specific type of honey of the receiver or communication link. The second communication module 540 further includes a mac module 560 communicably connected to the transceiver module 550. Similar to the module 520 of the first communication module 51 discussed above, the MAC module 560 includes a media access module 562. The media access module 562 and the media access module 522 of the first communication module 5110 discussed above have common characteristics in many aspects. The MAC module 560 further includes a control transmission module 564. The control transfer module 564 can use the transceiver module 550 to receive information from the first device and transfer control of the communication medium from the first device to the second device. After the communication media is controlled in this way, the MAC module 560 can access and control the communication media without performing various media access activities. For example, if the access to the communication media is managed by a competition-based media access protocol, such as CSMA / CA, the MAC module 560 can obtain the control of the communication media directly from the first device, thereby skipping the need to communicate with other media. Network equipment competes to gain access to communication media. The second communication module 540 also includes the transceiver modules 55 and μα. The module 560 can be connected to the data transmission module 580. The data transmission module 58 can use the transceiver module 550 to receive information from a network device. The data transmission module 580 can also use the transceiver module 550 to transmit information to other network devices. For example, before the MAC module 560 obtains control of the communication media from the first device to the second device, the data transmission module 58 may use the transceiver module 550 to receive information from the first device. This information includes data and / or control information and may also include media access delivery information. The media access transmission information may also be isolated information. As another example, as the MAC module 560 obtains control of the communication medium from the first device to the first delta device, the data transmission module 580 may use the transceiver module 550 to return information to the first device. In the exemplary embodiment where the second device is a network access point 26 200527192 device, the access point device may have stored information to be sent to the first device in a buffer and waited for the first device Instruction, or an indication that the first device is not in a sleep state in a power saving mode. The data transmission module 580 can be connected to an information buffer 590, which stores information to be sent to the first device. The data transmission module 58 can retrieve this information from the information buffer 590, and use the transceiver module 55 to transmit the information to the first device. For example, when the MAC module 56 maintains control of the communication medium, the data transmission module 580 can transmit the message to the first device through a single packet or packet stream. It should be noted that the information buffer 59 may be integrated or not integrated into the second communication module 540. For example, the information buffer 590 may be at an accessible location in the wired LAN 544. The first communication module 540 includes an energy-saving equipment database module 57, which is communicably connected to the LAN module in the MAC module 560. The energy-saving determination module 566 (for example, consistent with the control transmission module 564) may use the information of the energy-saving type database module 570 to determine whether the received media control transmission information is transmitted by the network equipment with energy-saving characteristics. The second communication module 540 can respond to this information differently according to the information source. For example, the second communication module 540 may decide not to accept control of the communication medium when responding to information received from a network device that does not have energy-saving features. In contrast, in response to the information received from the network equipment with energy-saving characteristics, the second communication module 54 will always receive control of the communication medium. Each module of the second communication module 540 may be integrated into a single integrated circuit. The various modules may include hardware, software, or a combination of hardware and software. The various modules may also share components of the second communication module 540, such as a microprocessor, a storage device, a bus structure, a clock, and so on. Therefore, the scope of the invention should not be limited to the specific arrangements and implementations of the various modules in question. The sixth diagram is a flowchart of a method for controlling access to a communication medium according to the present invention. The method 600 can be used in communication with network equipment with energy saving characteristics. However, the shed of the present invention should not be limited to this saki energy type equipment.

The sleep state of the network device may be disabled for various reasons, including but not limited to user actions or timer action requirements. In the alternative, the-device can perform some other pre-occupied actions. Month In step 620 of method 600, the first network device obtains access and control of the network communication medium. As mentioned above, this type of access and control can respond to one or more channels, frequencies, time slots, frequency hopping patterns, or encoding methods. The first network device may gain access to the communication medium by being based on a competing media access protocol (eg, CSMA / CA). In step 630 of method 600, the first network device transmits information to the second network device using a communication medium. The second network device may be an access point device in a wireless network. Alternatively, the second network device may be a peer device. Therefore, the scope of the present invention should not be limited to a specific device or network.

To transfer control of the communication media from the first network device to the second network device. The second network device may be the same network device as the first network device transmitting information in step 630. The second network setting allows communication media to be used after gaining control of the communication media without having to follow media access protocols that are commonly used to manage access to communication media. By way of example and not limitation, when access to a communication medium is managed by a competition-based media access control protocol (such as CSMA / CA), the second network device can use the communication medium 28 200527192 without having to communicate with other networks. Devices compete for access to communication media. Step 640 has two sub-steps. In step 642+, the first network device transmits a media control transfer information to the second network, device. The media control transmission information can be known from the first network device to indicate that the second network device can control the communication media. The media control transmission information can have multiple forms. For example, it's time to pass information, either-isolated information or multipurpose information-identification. The transmission information can be identified by one of the data packets with data and / or control information, and it can be set to indicate to the receiving device that the sending device has no dragon or no more to send. In step 644, the second network device that received the transmission information meets whether the network is a slightly energy-saving device. In the method, the second network device I distinguishes between energy-saving equipment and non-energy-saving equipment. For example, the second network device may receive the media control host of the "capable device instead of the non-power-saving device." "Allow transmission from the power-saving device but not from non- = ^ is only an exemplary case. It should not be a database of information about the present invention. The network equipment will analyze a database of known energy-saving equipment from the first network equipment. Information can be transmitted to No. Sakizaga. 3! In the case of CGN's exemplary energy saving, the second network device may have been-slowing down the traffic to the first network device, and waiting-indicating that 节能 is in energy saving After indicating the sleep state of the mode and receiving the control of the communication medium from the "C", the second network subtracts the information from the buffer g 29 200527192 'and uses the communication medium to transmit the retrieved information * in step 650. Including information transmitted by a single data packet or data packet to the first network 5 or another network device. In step 650, the communication media is also stunned in Vera, and the communication is transmitted by the communication miscellaneous. Therefore, the method 600 provides a kind of shop, and only needs to “the second time the successful control of the storage of the contact body”, the first network device and the second network device can transmit each other M §fl. In step 660 of method 600, the second network device releases control of the communication. In step 660, the second network device may transmit a message to make clear that it is releasing control of the contact body. In addition, in step 660, the second network 2 interrupts its use of the communication medium. Therefore, the scope of the present invention should not be limited to a specific mechanism that releases control of the communication media. It should be noted that the media access control of communication media includes some security measures to prevent a network entity or a group of network entities from controlling the communication media for more than an inappropriate period. For example, shipblade age may include an upper limit on the time that a “bribe or” group of devices can maintain control of the communication media without interference. As mentioned above, the present invention meets the requirements for invention patents, and the patent is filed according to law.
