Description

Network access method and device

Technical Field

The disclosure relates to the field of communication technologies, and in particular, to a network access method and device.

Background

The Wireless sensing (English: wi-Fi) protocol is a Wireless network (Wi-Fi) protocol based on a position proximity, so that the use of Wi-Fi can be expanded to a larger range, and the Wi-Fi device can realize low power consumption and rapid clicking to acquire services provided by other surrounding Wi-Fi devices through the Wi-Fi device without a cellular data network, wi-Fi hot spots or a global positioning system (Global Positioning System, GPS) connection.

In the process of using Wi-Fi Aware protocol, wi-Fi Aware equipment needs to do device Discovery, and in the process of doing device Discovery, a master device (English: master device) periodically sends a Discovery Beacon frame (English: discovery Beacon) on a channel to announce the existence of the device. New equipment (English: new device) needing to access the network monitors Discovery Beacon in a passive scanning (English: passive scan) mode to find the peripheral master device, and then adds the network where the master device is located according to the Discovery Beacon application.

In the process of sending Discovery Beacon, the master device wakes up and sends Discovery Beacon according to a fixed time interval (English) period, and immediately enters into a sleep state after the sending is completed.

It is desirable that the new device be able to predict the exact time that the master device sent the Discovery Beacon so that the new device wakes up at the exact point in time and receives the Discovery Beacon sent by the master device.

However, the ideal state cannot be achieved in the current Wi-Fi Aware access scheme, and time synchronization cannot be achieved between the new device and the master device, so that the new device depends on keeping active (english) for a longer time to do a passive scan, so as to achieve the purpose of discovering the master device and receiving Discovery Beacon sent by the master device.

Detailed Description

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.

Fig. 1 is a flowchart of an access method according to an exemplary embodiment, and as shown in fig. 1, the method is used in a first device, and includes the following steps S101-S102:

in step S101, a target reference time point transmitted by a target reference device is received.

In step S102, when the detection target reference time point reaches a first preset time point, a discovery beacon frame is transmitted; so that the second device wakes up at a second preset time point, which is later than the first preset time point, and prepares to receive the discovery beacon frame.

The target time point sent by the target reference device is used as third party time, so that the first equipment and the second equipment can agree on the receiving and transmitting time of the Discovery Beacon by taking the third party equipment as a reference, and the second equipment is guaranteed to finish the scheme of discovering network access with the lowest power consumption.

For example: the first device and the second device can be contracted to wake up and start sending the Discovery Beacon when the third-party time reaches a preset time point, and the second device can wake up to do a passive scan a little time before the third-party time reaches the preset time point so as to prepare to receive the Discovery Beacon sent by the first device, so that the first device can be prevented from needing keep active for a longer time to do a passive scan, and the power consumption of the first device is effectively reduced.

When the received target reference time point sent by the target reference device is 3:00, and when the first device and the second device can agree that the third party time reaches 5:00, the first device is awakened and starts to send Discovery beacons, and the second device can be awakened at 4:45 to do a passive scan in preparation for receiving the Discovery beacons sent by the first device. In an actual scene, when the second device detects that the target reference time point reaches 4:45, the second device is awakened to perform a passive scan so as to prepare to receive the Discovery Beacon sent by the first device, when the first device detects that the target reference time point reaches 5:00, the second device is awakened and starts to send the Discovery Beacon, and at the moment, the second device can scan the Discovery Beacon sent by the first device, so that the network access process is completed.

Of course, in the above embodiment, the first device and the second device may also be awakened at the same time, for example: the first device and the second device may agree that when the third party time reaches 5:00, the first device is awakened and starts to send the Discovery Beacon, and at the same time, the second device is awakened at 5:00 to make a passive scan to receive the Discovery Beacon sent by the first device. However, there may be a time difference between the process of waking up the first device and sending the Discovery Beacon and the process of waking up the second device and receiving the Discovery Beacon, so that the reliability of receiving the Discovery Beacon by the second device is low, that is, the second device may not receive the Discovery Beacon sent by the first device, but in practical application, the scheme may also be implemented.

The first device in this embodiment may be the master device described above, and the second device is the new device described above.

In one embodiment, the step S101 includes the following sub-steps A1-A2:

in A1, indication information sent by a plurality of reference devices is received simultaneously, where the indication information includes: reference time points.

In A2, selecting a target reference device from a plurality of reference devices according to a preset condition; the reference time point included in the indication information transmitted by the target reference device is a target reference time point.

If multiple reference devices may exist near the first device, the first device may receive the indication information carrying the reference time point sent by each reference device, but the first device and the second device need to agree a commonly accepted target reference device from the reference devices, so that the purpose of accessing the network with low power consumption is achieved by using the reference time point carried in the indication information sent by the target reference device as the target reference time point.

In one implementation, the first device and the second device may select the target reference means according to the time at which the indication information is received. For example: the first equipment and the second equipment both select the reference device corresponding to the received first indication information as the target reference device, or the first equipment and the second equipment both select the reference device corresponding to the received last indication information as the target reference device.

However, the above-mentioned selecting the target reference device according to the receiving time may have a problem that the reference device corresponding to the first indication information received by the first device is different from the reference device corresponding to the first indication information received by the second device, so that the target reference time point owned by the first device is different from the target reference time point owned by the second device, which may also cause that the second device cannot receive the Discovery Beacon sent by the first device, or the second device keeps the wake-up time longer.

In order to improve the reliability of network access, the above indicated information may include: referencing an identification code of the device; at this time, the above A2 includes the following substeps:

selecting the reference device with the largest identification code value as a target reference device;

Or alternatively, the process may be performed,

The identification code of the reference device can uniquely identify the reference device, so that the target reference devices selected by the first equipment and the second equipment from a plurality of reference devices are identical, and then the target reference time points owned by the first equipment and the second equipment are also identical, so that the second equipment can receive Discovery beacons sent by the first equipment, or the time for the second equipment to stay awake is reduced, and the power consumption of the second equipment is reduced.

For example, the identification code of the reference device may include a hardware Address (english) of the reference device.

A wireless access point (Wireless Access Point, abbreviated as wifi AP) is a common device, and an important role of a Beacon frame sent by the wireless access point is to issue a timing synchronization function (Timer Synchronization Function, abbreviated as TSF) value to a device on a network (english: device) periodically. Each device in the basic service area (Basic Service Set, abbreviated BSS) must hold a copy of the TSF value; the copy is an internal timer synchronized with the TSF values of all other workstations in the basic service area. The TSF operates at a 1MHz clock, jumping every microsecond (English: tick).

When the AP is ready to transmit a Beacon frame, the TSF value is copied to the Beacon frame's timestamp (64 bits) field. The device in connection with the AP will obtain the TSF value from the received Beacon frame, but will adjust slightly to account for the processing time of the antenna and transceiver. The device connected to the wifi AP maintains the internal TSF value, so that even if a Beacon frame is missed, the device can be roughly synchronous with the integral TSF value, and can be corrected by receiving the subsequent Beacon frame.

Since the Beacon frame sent by the AP carries the TSF value, the AP may be used as the target reference device in the present disclosure, and the step S101 includes the following substeps B1-B2:

in B1, a beacon frame transmitted by a target wireless access point AP device is received.

In B2, a timing synchronization function value is acquired from the beacon frame as a target reference point in time.

Most of the wifi aways use scenes such as markets, airports and other public places are basically provided with a large number of wifi APs, so that TSF values are relatively easy to obtain. The first device and the second device may agree to transmit and receive Discovery Beacon according to the TSF value for a precise time.

The first device may obtain the TSF value of the surrounding APs through wifi Beacon or Probe Response (english) frames on a 2.4/5G channel.

In one embodiment, since the first device or the second device has a certain delay for the beacon frame when receiving the beacon frame sent by the target AP device, the processing time of the antenna and the transceiver is included in the calculation, and at this time, the timing synchronization function value is obtained from the beacon frame as the target reference time point, which includes the following substeps C1-C2:

in C1, a timing synchronization function value is acquired from the beacon frame.

In C2, adding a preset processing value into the timing synchronization function value to obtain a target reference time point.

For example, the preset processing value may be obtained based on the processing time of the antenna and the transceiver.

In one embodiment, when the detection target reference time point reaches a first preset time point, a discovery beacon frame is transmitted, comprising the sub-steps of:

When the target reference time point is the TSF value or after the TSF value and the preset processing value, the first device transmits the discovery beacon frame when the value of the preset bit in the value is changed to the first preset value because the value is continuously changed.

For example: the first device transmits a discovery beacon frame when the lower 16bits of the TSF value is 0. Since the Time of discovery beacon frame transmission can be configured, for example, the Time of discovery beacon frame transmission needs to be 50 Time units (Time Unit, abbreviated as: TU; 1tu=1024 μs) or more and 200TU or less, and 2 ¹⁶ 64TU,2 ¹⁷ 128TU, so the first device may choose to send a discovery beacon frame when the lower 16bits is 0, or the lower 17bits is 0 in the corresponding scheme.

Fig. 2 is a flowchart of an access method according to an exemplary embodiment, and as shown in fig. 2, the method is used in a second device, and includes the following steps S201-S203:

in step S201, a target reference time point transmitted by a target reference device is received.

In step S202, when the detection target reference time point reaches a second preset time point, the wake-up state is entered to prepare for receiving a discovery beacon frame transmitted by the first device at the first preset time point, where the second preset time point is later than the first preset time point.

In step S203, after receiving the discovery beacon frame, it is applied to join a network corresponding to the first device that transmitted the discovery beacon frame.

The second device takes the target reference time point sent by the target reference device as the third party time in the same manner, and enters an awake state when the target reference time point reaches a second preset time point, so as to prepare to receive the discovery beacon frame sent by the first device at the first preset time point.

The implementation method of applying to join the network corresponding to the first device sending the discovery beacon frame after the second device receives the discovery beacon frame is the same as that in the related art, and is not repeated here.

In one implementation, the above step S201 includes the following sub-steps D1-D2:

in D1, indication information sent by a plurality of reference devices is received simultaneously, where the indication information includes: reference time points.

In D2, selecting a target reference device from a plurality of reference devices according to a preset condition; the reference time point included in the indication information transmitted by the target reference device is a target reference time point.

The implementation manner of the steps D1-D2 is the same as the steps A1-A2 in the above embodiment, and will not be repeated here.

In one implementation, the indication information includes: referencing an identification code of the device; the step D2 includes the following sub-steps:

or alternatively, the process may be performed,

The implementation manner of this step is the same as that in the above embodiment, and will not be described here again.

In one implementation, the above step S201 includes the following sub-steps E1-E2:

in E1, a beacon frame sent by the target wireless access point AP device is received.

In E2, a timing synchronization function value is acquired from the beacon frame as a target reference point in time.

The implementation manner of the steps E1-E2 is the same as the steps B1-B2 in the above embodiment, and will not be repeated here.

In one embodiment, the acquisition of the timing synchronization function value from the beacon frame as the target reference point in time includes the following substeps F1-F2:

In F1, acquiring a timing synchronization function value from a beacon frame;

in F2, adding a preset processing value into the timing synchronization function value to obtain a target reference time point.

The implementation manner of the steps F1-F2 is the same as that of the steps C1-C2 in the above embodiment, and will not be repeated here.

In one embodiment, entering the awake state when the detection target reference time point reaches a second preset time point comprises the sub-steps of:

and when the change of the value of the preset bit of the target reference time point to the second preset value is detected, entering an awake state.

When the target reference time point is the TSF value or after the TSF value and the preset processing value, the second device wakes up when the value of the preset bit in the target reference time point is changed to the second preset value due to the continuous change of the value.

For example: the first device transmits a discovery beacon frame when the lower 16bits of the TSF value is 0, then the second device wakes up some time in advance to ensure that the discovery beacon frame of the first device is received when the lower 16bits of the TSF value is about to be 0.

Fig. 3 is a flowchart of an access method according to an exemplary embodiment, as shown in fig. 3, including the following steps S301-S307:

In step S301, the first device receives indication information sent by a plurality of reference devices at the same time, where the indication information includes: reference time point and identification code of reference device.

In step S302, the first device selects the reference device with the largest identification code value as the target reference device; the reference time point included in the indication information transmitted by the target reference device is a target reference time point.

In step S303, the second device receives indication information sent by the plurality of reference devices at the same time, where the indication information includes: reference time point and identification code of reference device.

In step S304, the second device selects the reference device with the largest identification code value as the target reference device; the reference time point included in the indication information transmitted by the target reference device is a target reference time point.

In step S305, when the second device detection target reference time point reaches the second preset time point, the awake state is entered.

In step S306, when the first device detection target reference time point reaches the first preset time point, a discovery beacon frame is transmitted.

In step S307, after the second device receives the discovery beacon frame sent by the first device, it applies to join the network corresponding to the first device that sends the discovery beacon frame.

Step S301 and step S302 may occur before step S303 and step S304, may occur after step S303 and step S304, or may occur simultaneously with step S303 and step S304.

Fig. 4 is a flowchart of an access method according to an exemplary embodiment, as shown in fig. 4, including the following steps S401-S407:

in step S401, the first device receives beacon frames sent by a plurality of wireless access point AP devices and a hardware Address MAC Address of the AP device at the same time.

In step S402, the first device selects an AP device with the largest MAC Address as a target AP device; the timing synchronization function value included in the beacon frame transmitted by the target AP device is the target reference point in time.

In step S403, the second device receives beacon frames transmitted by the AP devices and MAC addresses of the AP devices simultaneously.

In step S404, the second device selects the AP device with the largest MAC Address as the target AP device; the timing synchronization function value included in the beacon frame transmitted by the target AP device is the target reference point in time.

In step S405, when the second device detects that the value of the preset bit of the timing synchronization function value is changed to the second preset value, the second device enters a wake-up state.

In step S406, when the first device detects that the value of the preset bit of the timing synchronization function value is changed to the first preset value, a discovery beacon frame is transmitted.

In step S407, after the second device receives the discovery beacon frame sent by the first device, it applies to join the network corresponding to the first device that sends the discovery beacon frame.

Step S401 and step S402 may occur before step S403 and step S404, may occur after step S403 and step S404, or may occur simultaneously with step S403 and step S404.

The above scheme in the embodiment of the disclosure is applicable to a usage scenario where the first device and the second device are relatively close to each other, so that the acquired lists of the peripheral AP devices are the same.

If the devices are far away or in places without routing, if the devices of the two parties contain a GPS or modem module, the devices can agree to send and receive Discovery beacons by means of a third party time such as GPS or base station timing, and the processing mode is similar to TSF time of a WIFI AP Beacon, and the GPS or modem module is the target reference device.
