Distance measurement method and electronic equipment

Technical Field

The distributed interconnection capability of the operating system is benefited, and interconnection and intercommunication of electronic devices such as intelligent wearable devices, intelligent household devices and mobile terminals are preliminarily realized.

After the connection is established between the plurality of electronic devices, the distance between the electronic devices needs to be determined, so that better user experience is provided for the user. For example, when the mobile phone is paired with a plurality of bluetooth headsets, after the bluetooth function of the mobile phone is turned on, it is found that at least two bluetooth headsets can be paired, and the mobile phone can be preferentially paired with headsets that are closer to each other.

The electronic device may measure the distance to other electronic devices by various methods, such as Ultra-Wideband (UWB) ranging, bluetooth ranging, laser ranging, etc. However, the ranging system represented by bluetooth ranging has low accuracy and large error, while the ranging system represented by UWB ranging has high power consumption, and requires an extra ultra wideband signal generating device, which is costly.

However, many electronic devices, such as bluetooth headset, bluetooth mouse, VR glasses, smart home devices, etc., are often powered by a built-in battery, and when the power consumption of the electronic device for performing ranging once is high, the endurance of the electronic device may be rapidly reduced. In contrast, when the electronic devices determine the distance between the electronic devices by using a low-power-consumption distance measurement method such as bluetooth distance measurement, the distance between the electronic devices cannot be accurately calculated by the electronic devices due to the accuracy of bluetooth distance measurement.

It should also be understood that the term "and/or" as used in this disclosure refers to and encompasses any or all possible combinations of one or more of the listed items.

The terms "first," "second," and the like, are used below for descriptive purposes only and are not to be construed as implying or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature, and in the description of embodiments of the application, unless otherwise indicated, the meaning of "a plurality" is two or more.

The term "User Interface (UI)" in the following embodiments of the present application is a media interface for interaction and information exchange between an application program or an operating system and a user, which enables conversion between an internal form of information and a form acceptable to the user. A commonly used presentation form of the user interface is a graphical user interface (graphic user interface, GUI), which refers to a user interface related to computer operations that is displayed in a graphical manner. It may be a visual interface element of text, icons, buttons, menus, tabs, text boxes, dialog boxes, status bars, navigation bars, widgets, etc., displayed in a display of the electronic device.

First, a use scenario of the ranging method provided by the embodiment of the present application is described.

With the development of communication technology and the popularization of intelligent devices, a plurality of electronic devices can be interconnected and intercommunicated. When a user performs some cross-device operation on a certain electronic device, the user is required to designate the operated device. In this case, when the number of other devices connected to the device is large, the user needs to search the list for the device to be operated, and the user experience is poor.

For example, a mobile phone is paired with a plurality of bluetooth headsets, and when the user turns on the mobile phone, the user is required to manually select the bluetooth headset to be paired.

Further, for some cross-device operations, limited by the specificity of the service, the distance between devices needs to be smaller than a certain threshold to enable the service to run normally. The service specificity can include two aspects, on one hand, the service has certain privacy, the distance between two devices is required to be smaller than a threshold value, and the risk of privacy and identity disclosure caused by misoperation is reduced; on the other hand, the communication capacity/communication protocol which comprises the service dependence is greatly influenced by the distance, and when the distance between two electronic devices is far, the quality of the communication which is the service dependence cannot be ensured, so that bad experience to a user is avoided.

For example, for a service with shared internet access capability, in order to ensure a data transmission rate and a delay of the service, signals in a higher frequency band (such as a WIFI 5G frequency band) are often selected to perform data transmission. However, attenuation of a transmission signal through a channel of a high-frequency band is greater along with attenuation of a distance, and in this case, it is required that a distance between electronic devices is smaller than a certain upper distance limit, so that services represented by a network access capability sharing service can be ensured to stably run, and user experience is ensured.

The following describes a scenario of a ranging method according to an embodiment of the present application in an exemplary manner, with reference to fig. 1A, 1B, 1C, and 2.

In a home or office, after the electronic device establishes a connection with a plurality of other electronic devices, the devices can be operated simultaneously by a multi-screen collaboration mode, a screen throwing mode and the like. As shown in fig. 1A, there are connections between the electronic apparatus 3 and other plural electronic apparatuses. Wherein the plurality of electronic devices includes an electronic device 1 and an electronic device 2.

When the number of other electronic devices connected with the electronic device is large, a user is required to manually search for the device requiring multi-screen collaboration and screen projection. For example, if the user wants to display the interface of the electronic device 2 on the electronic device 3 through the multi-screen collaboration function, the user needs to find the electronic device 2 in the device list in the electronic device 3, as shown in fig. 1B.

As shown in fig. 1B, the electronic device 3 can display only a limited number of connected devices on one page of the device list, limited by the screen size of the electronic device 3. And because the user does not know which page of the device list the electronic device 2 is on, the user needs to turn pages to find the control 101 corresponding to the electronic device 2, and then clicks the control 101 to start multi-screen collaboration.

In the content shown in fig. 1B, the control 101 corresponding to the electronic device 2 is on the second page of the device list.

Obviously, the operation is very tedious, and the user experience is poor. In order to simplify the operation of the user and improve the experience of the user, the electronic equipment 2 and/or the electronic equipment 3 can determine the distance between the electronic equipment through the distance measuring method provided by the embodiment of the application, and correspondingly adjust the positions of the controls corresponding to the electronic equipment according to the distance between the electronic equipment, thereby simplifying the operation of the user and improving the experience of the user.

After the electronic device 3 executes the ranging method provided by the embodiment of the present application, the electronic device 3 may determine that the electronic device 2 is closest to the electronic device 3, and then the electronic device 1 is next closest. Therefore, the controls corresponding to the electronic device 2 and the electronic device 1 can be placed on the first page of the device list, so that the user can conveniently select the controls.

As shown in fig. 1C, the control 101 corresponding to the electronic device 2 is on the first page of the device list. Similarly, the control corresponding to the electronic device 1 is also on the first page of the device list.

As shown in fig. 2, the electronic device 1 was paired with the bluetooth headset 1 and the bluetooth headset 2. When the electronic device starts the Bluetooth function, the Bluetooth headset 1 with the closer distance is preferentially selected to initiate the connection request, and the Bluetooth headset 2 with the farther distance is not preferentially selected to initiate the connection request, so that the Bluetooth headset 1 and the electronic device 1 are preferentially paired.

Similarly, when more than two Bluetooth headsets are in a standby state or a starting state, the electronic device can be preferentially matched with the Bluetooth headsets with a relatively close distance, and further the user experience is improved by reducing the user operation.

Further, for some special services, such as internet access capability sharing service, short message sharing service, call sharing service, etc., it is necessary to ensure that the distance between multiple electronic devices is smaller than a certain upper distance limit. For the special services above, the privacy and security of the user are considered, and the communication capability/communication protocol depending on the service is considered to be greatly affected by the distance, and because the functions of flow, short message content, call recording, dialing and the like often relate to the personal and property safety of the user, the electronic equipment needs to ensure that the distance between a plurality of electronic equipment is smaller than a certain distance upper limit in the process of running the special services.

For example, a connection is established between the mobile phone and a tablet that is not connected to the network, the mobile phone is connected to the network through a data traffic service authorized by the SIM card, and the tablet is not connected to the network. In the case where the distance between the handset and the tablet is less than a certain threshold, a prompt may be displayed on the tablet or the handset for asking the user if to share the data traffic of the handset to the tablet so that the tablet is connected to the network through the data traffic of the handset.

For example, a connection is established between the tablet personal computer and the mobile phone without the SIM card, and under the condition that the distance between the mobile phone and the tablet personal computer is smaller than a certain threshold value, the mobile phone or the tablet personal computer can create a call sharing service and a short message sharing service, so that a user can directly use the tablet personal computer to dial a call and send and receive a short message, the operation of the user is convenient, and the experience of the user is improved.

The following describes a scenario of a ranging method according to an embodiment of the present application in an exemplary manner, with reference to fig. 3 and 4.

After the handset and the tablet without networking establish a connection, the handset or tablet may determine the distance R of the peer device, as shown in fig. 3. The mobile phone or the tablet can determine whether to create the internet surfing capability sharing service according to the change of the distance between the opposite terminal devices.

For example, in the case where the distance R is greater than the distance upper limit, it is determined that the internet surfing capability sharing service is not created because the distance between the mobile phone and the tablet is long; in the case where the distance R is less than the upper distance limit, it is determined to create the internet surfing capability sharing service due to the closer distance between the handset and the tablet, or the user is queried through the notification 301 in fig. 3 whether to create the internet surfing capability sharing service.

The notification 301 may include the word "current network unavailable, sharable cell phone network online.

It should be noted that, in the case that the distance R is greater than the upper distance limit, the internet surfing capability sharing service may also exist, but the related operation is not executed; in the case that the distance R is smaller than the upper distance limit, the mobile phone and/or the tablet may perform related operations of the internet sharing service.

After the handset and the tablet without the SIM card are connected, the handset or tablet may determine the distance R of the opposite device, as shown in fig. 4. The mobile phone or the tablet can determine whether to create a call sharing service and a short message sharing service and whether to execute operations corresponding to the call sharing service and the short message sharing service according to the change of the distance between the opposite terminal devices.

For example, in the case that the distance R is greater than the upper limit of the distance, since the distance between the mobile phone and the tablet is far, it is determined that the call sharing service and the short message sharing service are not created; and under the condition that the distance R is smaller than the upper limit of the distance, establishing call sharing service and short message sharing service due to the fact that the distance between the mobile phone and the tablet is relatively short.

Similar to fig. 3, in the case where the distance R is greater than the distance upper limit, a call sharing service, a short message sharing service may also exist, except that the related operation is not performed; and under the condition that the distance R is smaller than the upper limit of the distance, the mobile phone and/or the tablet can execute related operations of the call sharing service and the short message sharing service.

Before the call sharing service and the short message sharing service are created, the interface displayed on the tablet comprises a control 401, a control 402, a control 403 and a control 404. Where control 401 corresponds to a music application, control 402 corresponds to a control of a clock application, control 403 corresponds to a control of a theme application, and control 404 corresponds to more options.

After the call sharing service and the short message sharing service are created, the interface displayed on the tablet comprises a control 405, a control 406, a control 401 and a control 404. Where control 405 corresponds to a conversation application and control 406 corresponds to an information application.

The user can click on the control 405, start a call application program, and perform operations such as making a call; similarly, the user may click on the control 406 to start the short message application program, perform operations such as sending a short message, and the like.

In connection with what is set forth above, it is apparent that in many different scenarios, the implementation of many functions, services on an electronic device depends on the outcome of the electronic device performing ranging.

One possible ranging method may be: meanwhile, the distance measurement is carried out through a Bluetooth distance measurement method and an ultra-wideband distance measurement method, and the distance measurement results of the two methods are subjected to weighted average, so that a distance is obtained.

However, this ranging method has two non-negligible drawbacks.

First, this coupled ranging approach does not reduce the range error.

Let the error of bluetooth ranging be p _bluetooth (r)，p _bluetooth (r) increases with increasing distance r; the error of UWB ranging is p _UWB ，P _UWB The correlation with the distance r is low.

If the Bluetooth ranging method and the ultra-wideband ranging method are coupled, the following formula (1) is adopted:

r＝r _bluetooth *k _bluetooth +r _UWB *k _UWB #(1)

wherein r is the result measured by the ranging method, r _bluetooth Distance, k, measured for bluetooth ranging _bluetooth Weights for bluetooth ranging; r is (r) _UWB Distance, k, measured for UWB ranging _UWB Weights for UWB ranging.

It is evident that in case the error of bluetooth ranging is higher than the error of UWB ranging, r _UWB Closer to the real distance between two electronic devices, the result r of Bluetooth ranging after being processed as shown in formula (1) _bluetooth R can be contaminated such that r is further from the true distance between the devices. In case the error of the bluetooth ranging is higher than the error of the UWB ranging, the result r of the bluetooth ranging _bluetooth R can be contaminated such that r is further from the true distance between the devices.

For example, the distance between two electronic devices is 1.5m, the result r of UWB ranging _UWB 1.6m, and the bluetooth ranging result is 1.7m. At k _bluetooth ＝k _UWB In the case of=0.5, the result r=1.65m calculated according to the formula (1). It is evident that the UWB ranging result is closer to two electronic devicesTrue distance between the devices.

Secondly, this coupled ranging approach can dramatically increase the power consumption of the electronic device.

Obviously, the coupled ranging mode requires the electronic device to perform bluetooth ranging and UWB ranging simultaneously, which can dramatically increase the power consumption of the electronic device to perform one ranging.

Besides, UWB ranging requires a corresponding dedicated ultrasonic signal generating device on the electronic device, which is costly.

In connection with the above description, it will be appreciated that, first, the ranging method of coupling UWB ranging and bluetooth ranging cannot be balanced in terms of power consumption and accuracy. Secondly, the UWB ranging and Bluetooth ranging coupling ranging method does not consider the service requirement, and increases the power consumption of the electronic equipment. For example, in the case where the error of bluetooth ranging is greater than that of UWB ranging, the bluetooth ranging result may also satisfy the requirement of distance insensitive service, in which case, the electronic device increases power consumption by using UWB ranging, and the increase of ranging accuracy does not bring corresponding benefit to service.

Secondly, the distance measuring method and the electronic device provided by the embodiment of the application are introduced.

Since in many scenarios the function, service implementation of an electronic device requires accurate ranging results, the scenarios shown in fig. 1A, 1B, 1C, 2, 3, 4 above; further, since the electronic device may be a device with limited battery capacity such as a bluetooth headset, a smart watch, and a smart bracelet, it is necessary to reduce power consumption of the electronic device for performing ranging.

In view of the foregoing, the embodiment of the application provides a ranging method and electronic equipment. The distance measuring method provided by the embodiment of the application can reduce the power consumption of the electronic equipment for executing the distance measurement under the condition of ensuring the distance measurement precision.

The ranging method provided by the embodiment of the application comprises the following steps: and under the condition that the electronic equipment carries out distance measurement on other equipment for the first time, selecting a distance measurement mode with the shortest time consumption or the lowest power consumption to carry out distance measurement. In the case that the electronic device does not measure the distance for the first time to other devices, the distance is determined according to the last measurement, and an appropriate distance measurement mode is selected to perform distance measurement based on the distance.

It can be appreciated that in the case where the electronic device measures the distance for the first time to other devices, the electronic device may select the distance measurement mode with the shortest time consumption, because the distance measurement result may affect whether some services are created, the display sequence of the controls on the interface, and so on, and the distance measurement needs to be completed as soon as possible. Or, the distance measurement result may also affect the selection of the subsequent distance measurement mode, so the electronic device may select the distance measurement mode with the smallest error.

The ranging method provided by the embodiment of the application further comprises the following steps: under the condition that the distance between the opposite terminal equipment is required to be continuously determined, when two electronic equipment are stationary, only one ranging is executed; in the case where either one of the two electronic devices moves, ranging is periodically performed.

It will be appreciated that in the case where at least one of the two electronic devices is moving, the distance between the two electronic devices may vary, requiring the electronic devices to periodically perform ranging.

The ranging method provided by the embodiment of the application further comprises the following steps: when the electronic device performs ranging once to obtain a plurality of distances, a distance with the smallest distance may be preferentially selected as a result of the ranging.

It will be appreciated that ranging methods including bluetooth ranging, UWB ranging, ultrasonic ranging do not follow a random or normal distribution with true distance as a mean, due to errors, noise effects. Instead, the distance measured by the ranging method is always greater than the true distance.

The ranging method provided by the embodiment of the application further comprises the following steps: after two or more electronic devices including electronic device 1 and electronic device 2 have established a connection, when electronic device 1 measures the distance between electronic device 1 and electronic device 2, electronic device 2 may be triggered to measure the distance between electronic device 2 and electronic device 1, and electronic device 1 and electronic device 2 may select the smaller of the two ranging results.

The ranging method provided by the embodiment of the present application is exemplarily described below with reference to the content shown in fig. 5.

As shown in fig. 5, the ranging method provided by the embodiment of the application includes steps S501 to S511. Step S501 includes a triggering opportunity of the ranging method; step S502, step S503, step S504, and step S505 are specific steps of the ranging method in the case where the first electronic device and the second electronic device are both in a stationary state; step S506, step S507, step S508, step S509, step S510, and step S511 are specific steps of the ranging method in the case where the first electronic device and the second electronic device are not both in the stationary state.

These steps are described separately below.

S501: after the first electronic equipment and the second electronic equipment are connected, a first distance measurement mode is selected to perform distance measurement, and the first distance is determined.

The first electronic device establishes a connection with the second electronic device. The connection may be established by WIFI, bluetooth, near Field Communication (NFC), zigBee, apple wireless direct connection (Apple Wireless Direct Link, AWDL), hiLink, and the like, which are not limited herein.

After the first electronic device establishes a connection with the second electronic device, the first electronic device may transmit first data through the connection, the first data including a device ID for ranging. The device ID may be used to verify whether the electronic device that receives the ranging signal sent by the first electronic device is the electronic device that is being measured, i.e. the second electronic device may determine, according to the device ID, that it is the distance measured by the first electronic device. Wherein the ranging signal may be transmitted by the first electronic device in the form of a broadcast rather than in the form of a point-to-point communication.

The device ID may be preset inside the first electronic device and the second electronic device, or may be determined by negotiation after the first electronic device and the second electronic device establish connection.

Optionally, in some embodiments of the present application, after the first electronic device establishes a connection with the second electronic device, the first electronic device or the second electronic device determines that the first condition is met, and selects the first ranging mode to perform ranging. Wherein the first condition may be different from scene to scene. Alternatively, in some embodiments of the present application, in the scenarios shown in fig. 1A, fig. 2, fig. 3, and fig. 4, the first condition may be null, that is, after the electronic device and the second electronic device establish a connection, the ranging may be performed in the first ranging mode. Alternatively, in some embodiments of the present application, in the scenario illustrated in fig. 3, the first condition may be that one of the electronic device and the second electronic device is not networked; alternatively, in the scenario illustrated in fig. 4, the first condition may be that one of the electronic device and the second electronic device has no call capability. Then, the electronic device and/or the second electronic device select a first ranging mode to perform ranging, and the ranging result is the first distance.

Alternatively, in some embodiments of the present application, the ranging method may be selected randomly as the first ranging method.

Alternatively, in some embodiments of the present application, the least time-consuming ranging mode may be selected. It can be understood that the ranging mode with the shortest time consumption is selected, so that the first distance can be quickly obtained, and then the distances of a plurality of opposite terminal devices can be quickly determined, or whether to create services such as internet surfing capability sharing service, short message sharing service, call sharing service and the like can be quickly determined.

Alternatively, in some embodiments of the present application, the ranging mode with the lowest power consumption may be selected. It can be appreciated that selecting the ranging mode with the lowest power consumption can reduce the power consumption of the electronic device. And considering that the ranging mode with the lowest power consumption is often not the ranging mode with the smallest error, in the subsequent step, the ranging may be performed by selecting an appropriate ranging mode based on the first distance. Optionally, in some embodiments of the present application, the electronic device may store a ranging mode table locally or at the cloud, where the ranging mode table includes parameters such as error, power consumption, and time consumption of each ranging mode, as shown in table 1 below.

Table 1 is an exemplary schematic illustration of a ranging mode table provided in an embodiment of the present application.

	Error of	Power consumption	Time consuming
				Bluetooth ranging	p _bluetooth (r)	pw _bluetooth	T _bluetooth
Ultrasonic ranging	p _ultrasonic (r)	pw _ultrasonic	T _ultrasonic
				UWB ranging	p _UWB (r)	pw _UWB	T _UWB

As shown in table 1 above, the error of bluetooth ranging is p _bluetooth (r) Power consumption of Bluetooth ranging is pw _bluetooth Time consuming for bluetooth ranging is T _bluetooth The method comprises the steps of carrying out a first treatment on the surface of the The error of ultrasonic ranging is P _ultrasonic (r) ultrasonic rangingIs pw _ultrasonic Time consuming of ultrasonic ranging is T _ultrasonic The method comprises the steps of carrying out a first treatment on the surface of the The error of UWB ranging is p _UWB (r), UWB ranging power consumption of pw _UWB Time consuming UWB ranging T _UWB . Where r is the true distance between the object being measured and the electronic device. The error of ultrasonic ranging and the error of UWB ranging can be irrelevant to r.

It should be noted that, because the electronic device may not be able to obtain the real distance between the second electronic device and the first electronic device, the distance determined by the ranging manner may be directly used as the real distance, so as to determine the error of the first distance measured by different ranging manners. For convenience of explanation, hereinafter, an error of a distance determined by an electronic device performing any one ranging method is referred to as an error of the ranging method.

It should be noted that the errors of different ranging methods are also related to other parameters, and table 1 is merely an exemplary illustration of distances.

Therefore, the electronic device may determine the ranging mode with the shortest time consumption or the ranging mode with the lowest power consumption through table 1.

It should be noted that table 1 is only an exemplary schematic table of a ranging mode table, and the ranging mode table may further include more or fewer items, for example, may further include errors, power consumption and time consumption of ranging modes under different hardware modules. For example, the Bluetooth chip 1 takes a seconds, and the Bluetooth chip 2 takes b seconds. It will be appreciated that the same ranging mode for different hardware modules may also vary in time consumption, error, power consumption.

Optionally, in some embodiments of the present application, the distance measurement mode that can be performed by the electronic device is often fixed, and the hardware module on the electronic device is also fixed. A developer can configure different configuration files on different types of electronic devices, and the configuration files are marked with a ranging mode with the lowest power consumption and a ranging mode with the shortest time consumption. The electronic device can directly determine the ranging mode with the lowest power consumption or directly determine the ranging mode with the shortest time consumption by reading the configuration file.

S502: and judging whether the first electronic device and the second electronic device are both static.

The first electronic device determines whether both the first electronic device and the second electronic device are stationary. If the first electronic device and the second electronic device are both stationary, step S503 is executed; if the first electronic device and the second electronic device are not both stationary, step S506 is performed.

The first electronic device may send a message to the second electronic device over the connection, the message including whether the first electronic device itself is stationary or mobile. Similarly, the second electronic device may send the message to the electronic device over the connection. Further, the electronic device may know whether the first electronic device itself and the second electronic device are both stationary.

Wherein the first electronic device may determine whether itself is stationary based on the acceleration sensor, and similarly the second electronic device may determine whether itself is stationary based on the acceleration sensor.

S503: and judging whether the first ranging mode is the ranging mode with the minimum ranging error on the first distance.

The first electronic device and/or the second electronic device determines whether the first ranging mode is a ranging mode with the smallest ranging error on the first distance, and if the first ranging mode is a ranging mode with the smallest ranging error on the first distance, step S504 is executed; if the first ranging mode is not the ranging mode with the minimum ranging error on the first distance, step S505 is executed.

In step S501, the electronic device may select the first ranging mode in a plurality of manners.

S504: the result of determining the ranging is a first distance.

The first electronic device and/or the second electronic device determines a first distance as a result of the first distance measurement mode distance measurement, wherein the first electronic device and/or the second electronic device uses the first distance as a distance between the electronic device and the second electronic device.

Optionally, the electronic device may further send a message to the second electronic device through the connection, where the message includes the first distance and is used to notify the second electronic device of the distance between the two.

S505: and selecting a second ranging mode to perform ranging, and determining the second distance, wherein the second ranging mode is the ranging mode with the smallest ranging error on the first distance.

Since the first ranging mode is not the ranging mode with the smallest ranging error on the first distance, the first electronic device and/or the second electronic device may select the second ranging mode to perform ranging. The first electronic device and/or the second electronic device may determine that the ranging mode with the smallest ranging error on the first distance is the second ranging mode by the method shown in table 1, and then the first electronic device and/or the second electronic device perform ranging to determine the second distance.

For example, the distance between the electronic device 1 and the electronic device 2 is 2.75m, the first ranging mode is bluetooth ranging, the second ranging mode is ultrasonic ranging, the error of bluetooth ranging is smaller than that of ultrasonic ranging within 0.5m, and the error of bluetooth ranging is larger than that of ultrasonic ranging outside 0.5 m. Limited to the error of bluetooth ranging, the electronic device determines a first distance of 3m in step S501. Then, the electronic device may determine that the error of the bluetooth ranging is greater than the error of the ultrasonic ranging on the first distance 3m, and the electronic device selects the second ranging mode to be the ultrasonic ranging. The electronic device performs ultrasonic ranging, determining a distance of 2.85m.

It can be understood that, in combination with step S504 and step S505, the electronic device measures the first distance by using the ranging mode with the lowest power consumption, and then measures the second distance by using the ranging mode with the smallest error on the first distance, which combines both power consumption and accuracy.

S506: and performing ranging in a third ranging mode, determining the third distance, wherein the third ranging mode is the ranging mode with the lowest power consumption.

And when at least any one of the first electronic equipment and/or the second electronic equipment is moved, the distance between the electronic equipment possibly changes, and the first electronic equipment and/or the second electronic equipment periodically perform distance measurement in a third distance measurement mode to determine a third distance. The third ranging mode is the ranging mode with the lowest power consumption, and the electronic device may determine that the ranging mode with the lowest power consumption is the third ranging mode through the mode shown in table 1.

It can be appreciated that, because the distance between the electronic devices changes, the ranging mode with the lowest power consumption can be selected to perform ranging, and thus the power consumption of the electronic devices can be reduced.

S507: and judging whether the error of the third ranging mode on the third distance is smaller than an error threshold value.

Judging whether the error of the third ranging mode on the third distance is smaller than an error threshold value, if so, executing step S508; if not, step S509 is performed.

Wherein the error threshold may be a fixed value representing the maximum error that the electronic device may accept.

Wherein the error threshold may be a variable. For example, the error threshold may be related to the traffic triggering the electronic device to perform ranging, and the error threshold may be different for different traffic as shown in table 2 below.

Alternatively, in some embodiments of the present application, the error threshold may become infinite when the third distance is greater than a certain threshold. For example, the third distance is greater than the upper distance limit for all traffic. For another example, the third distance is greater than some fixed threshold preset on the electronic device.

Table 2 is an exemplary schematic representation of the error threshold versus traffic provided by an embodiment of the present application.

Service triggering ranging	Error threshold	Upper limit of distance
			Pairing services	Threshold 1	Upper limit of distance 1
Internet surfing capability sharing service	Threshold 2	Upper distance limit 2
			Call sharing service	Threshold 3	Upper distance limit 3
Short message sharing service	Threshold 4	Upper distance limit 4

As shown in table 2, different traffic corresponds to different error thresholds. Pairing service corresponds to a threshold 1, internet surfing capability sharing service corresponds to a threshold 2, call sharing service corresponds to a threshold 3, and short message sharing service corresponds to a threshold 4. Similarly, different services correspond to different upper distance limits, pairing tasks correspond to an upper distance limit 1, internet surfing capability sharing services correspond to an upper distance limit 2, conversation sharing services correspond to an upper distance limit 3, and short message sharing services correspond to an upper distance limit 4.

Optionally, in some embodiments of the present application, the upper distance limit represents a maximum value of distances between two electronic devices running the service, and when the distance between the two electronic devices is greater than the upper distance limit required by the service, the service is logged off; when the distance between the two electronic devices is smaller than the upper limit of the distance required by the service, the service starts to run or certain operations of the service are executed.

Alternatively, in some embodiments of the present application, the service is not logged off when the distance between the two electronic devices is greater than the upper distance limit of the service.

The threshold 1 corresponding to the pairing task is generally larger, that is, the pairing task may allow a certain error in the ranging result. This is because, for the pairing service, it is more likely that the plurality of second electronic devices are relatively far from the first electronic device. And the distance measurement is performed on the different second electronic devices in a short time, and the error of the distance of the different second electronic devices, which is determined by the first electronic device through any distance measurement mode, hardly influences the distance sorting of the distances between the different second electronic devices and the first electronic device.

For example, after bluetooth is turned on, the electronic device 1 performs ranging for the surrounding bluetooth headset. The bluetooth headset that the electronic device periphery can find once paired includes bluetooth headset 1 and bluetooth headset 2. The electronic device may establish a connection with the bluetooth headset 1 and the bluetooth headset 2, respectively, or may establish a connection with the bluetooth headset 1 and the bluetooth headset 2 simultaneously. After the connection is established, the pairing task triggers ranging for bluetooth headset 1 and bluetooth headset 2. The electronic equipment determines that the distance between the Bluetooth headset 1 and the Bluetooth headset 2 is 1.4m and 1.5m respectively, the real distance between the Bluetooth headset 1 and the Bluetooth headset 2 and the electronic equipment is 1.43m and 1.47m, and the error caused by ranging is positive and negative 0.03m respectively. Even if the distance measurement error is enlarged to 0.04m, the distances between the Bluetooth headset 1 and the Bluetooth headset 2 determined by the electronic device are 1.44m and 1.46m respectively, and the distance between the Bluetooth headset 1 and the electronic device determined by the electronic device is still not influenced to be smaller than the distance between the Bluetooth headset 2 and the electronic device.

It will be appreciated that in the examples above, even where the error is most extreme, in part, the error does not affect the relative near-far relationship of the two second electronic devices and the first electronic device. For example, when the distance between the two second electronic devices is greater than 2 times the error of the ranging result, the first electronic device does not erroneously determine the relative near-far relationship between the two second electronic devices and the first electronic device.

The threshold 2 corresponding to the internet surfing capability sharing service is generally smaller, that is, the result of the distance measurement required by the internet surfing capability sharing service has smaller error. The first reason is that the internet surfing capability sharing service is directly related to property safety of the user as a private service, and the second electronic device needs to be ensured to be within a certain distance, so that the electronic device sharing the internet surfing capability to the second electronic device needs to obtain an accurate ranging result. Secondly, the communication protocol/communication capability on which the internet surfing capability sharing service depends is sensitive to distance changes, different communication protocols may need to be adopted for different distances, and the power of a transmitter may need to be adjusted according to different distances so as to ensure the quality of the internet surfing capability sharing service.

For example, the upper limit of the distance between the internet surfing capability and the service is 5m, and when the distance between the second electronic device and the electronic device is smaller than 5m, the creation of the internet surfing capability and the service is triggered, as shown in fig. 3 above. After the internet surfing capability sharing service is created and validated, if the distance between the second electronic equipment and the electronic equipment is greater than 5m, the internet surfing capability sharing service can be logged off; if the distance between the second electronic device and the electronic device is smaller than 5m, the distance between the two electronic devices can be used for adjusting the communication protocol and the power of the transmitter, on which the internet surfing capability is dependent, of the sharing service.

The call sharing service and the sms sharing service are similar to the internet surfing capability sharing service in terms of distance requirements, and are different in terms of the difference in the amount of data transmitted by text information or voice information compared with the data traffic transmission, so that the distance measurement error threshold is different.

S508: and determining the ranging result as a third distance.

Because the error of the third ranging mode is smaller than the error threshold, the requirement of the service can be met, and the third distance can be used as a ranging result.

S509: and determining a ranging mode smaller than the error threshold value as a fourth ranging mode based on the last obtained distance and the error threshold value, executing the fourth ranging mode, and determining a fourth distance.

And determining a ranging mode smaller than the error threshold value based on the last obtained distance and the error threshold value, executing the ranging mode and determining a fourth distance. Wherein the fourth ranging scheme may be the same as the third ranging scheme.

Before determining the fourth distance, the last obtained distance may be substituted into the formula shown in table 1 above, thereby obtaining the error of different ranging modes. By comparing the magnitude relation between the errors of different ranging modes and the error threshold value, the ranging mode smaller than the error threshold value can be determined.

When there are a plurality of ranging methods with an error smaller than the error threshold, one ranging method may be selected at random, or a ranging method with low power consumption may be selected, which is not limited herein.

It should be noted that, unlike the above steps S503 and S507, the error of the ranging scheme determined in step S509 cannot represent the error of the fourth distance, and the error of the ranging scheme at a certain distance in steps S503 and S507 represents the error of the distance obtained by the ranging scheme.

It should be noted that, if the distance is determined through step S503, step S504 or step S505 when the first electronic device and/or the second electronic device are in the stationary state, in some embodiments of the present application, after determining that the first electronic device and the second electronic device are not both stationary, step S506, step S507 and step S508 may be skipped, and step S509 may be directly executed.

S510: and judging whether the error of the fourth ranging mode on the fourth distance is smaller than an error threshold value.

The first electronic device and/or the second electronic device determines whether the error of the ranging mode at the fourth distance is less than an error threshold. If the error of the ranging mode is greater than or equal to the error threshold on the fourth distance, step S509 is executed; if the error of the ranging method is smaller than the error threshold value at the fourth distance, step S511 is performed.

S511: and determining the distance measurement result as a fourth distance.

The first electronic device and/or the second electronic device determines that the result of the ranging is a fourth distance.

It should be noted that, the distance measurement result is the distance between the two electronic devices determined by the first electronic device and/or the second electronic device, and the distance greater than the error threshold value determined in the distance measurement process may not be the distance between the two electronic devices.

It should be noted that, after the electronic device and the second electronic device stop moving in the process of executing steps S506, S507, S508, S509, S510, and S511, similarly to step S503, it is determined whether the ranging mode of last performing ranging is the ranging mode with the smallest error on the distance obtained by last ranging, if so, the result of last ranging is taken as a final result; if not, selecting the ranging mode with the smallest error on the distance obtained by the last ranging to execute the ranging mode, and taking the ranging result as the final result, and further adjusting the connection-dependent protocol or adjusting the power of the transmitter.

It should be noted that, in the process of executing step S506, step S507, step S508, step S509, step S510, and step S511, the electronic device performs ranging in a periodic manner. More specifically, after the first electronic device and/or the second electronic device change from rest to motion, the ranging is performed by the ranging mode with the lowest power consumption at first, and when the ranging is smaller than the error threshold, the ranging mode with the lowest power consumption is performed next, which is equivalent to periodically performing the ranging by using the third ranging mode.

When the first electronic device and the second electronic device each perform the ranging method as shown in fig. 4, the ranging results obtained respectively are distance 1 and distance 2. After the first electronic device and the second electronic device exchange the distance 1 and the distance 2 through the connection, a smaller value of the distance 1 and the distance 2 can be selected as a ranging result.

Alternatively, in some embodiments of the present application, after the first electronic device and the second electronic device exchange the distance 1 and the distance 2 through the connection, an average value of the distance 1 and the distance 2 may be selected as a ranging result.

It should be noted that the first electronic device and the second electronic device may exchange distances each determined by the same ranging method, and then determine a distance based on the two distances as a ranging result, where a method of determining a distance based on the two distances as a ranging result may be a method of selecting a smaller value of the two distances as a ranging result, or selecting an average value of the distance 1 and the distance 2 as a ranging result, which is not limited herein.

In the following, examples of ranging modes that can be executed by the electronic device include bluetooth ranging and ultrasonic ranging, and an exemplary procedure for executing the ranging method provided by the embodiment of the present application by the electronic device is described. The following first exemplarily describes bluetooth ranging and ultrasonic ranging.

As shown in fig. 6A, bluetooth ranging may include step S6A01, step S6A02, step S6A03, step S6A04.

S6A01: a connection is established and a device ID is negotiated.

After the electronic device 1 and the electronic device 2 establish a connection, device IDs for ranging of the electronic device 1 and the electronic device 2 may be negotiated and determined. The connection may be established by WIFI, bluetooth, near Field Communication (NFC), zigbee, and the like, which is not limited herein.

S6a02: a ranging signal carrying the device ID of the electronic device 2 is transmitted.

The electronic device 2 transmits a ranging signal carrying the device ID of the electronic device 2.

S6a03: distance 1 is determined based on a received signal strength indication (RSSI, received signal strength indication) of the ranging signal.

The electronic device 1 determines the distance 1 based on the RSSI, where the RSSI is related to the distance of signal transmission, and reference may be made to the content shown in fig. 6C below, which is not described herein.

S6a04: a message carrying the device ID of the electronic device 1, distance 1 is sent.

The electronic device 2 sends a message carrying the device ID of the electronic device 2, distance 2. The electronic device 1 can determine the distance 1 from the message.

As shown in fig. 6B, bluetooth ranging may include step S6B01, step S6B02, step S6B03, step S6B04, step S6B05, step S6B06.

S6B01: a connection is established and a device ID is negotiated.

S6B02: a ranging signal 1 carrying the device ID of the electronic device 2 is transmitted.

The electronic device 1 transmits a ranging signal 1 carrying the device ID of the electronic device 2.

S6B03: distance 1 is determined based on the received signal strength indication of ranging signal 1.

The electronic device 2 receives the ranging signal 1 and determines the distance 1 based on the RSSI.

S6B04: a ranging signal 2 carrying the device ID of the electronic device 1 is transmitted.

The electronic device 2 transmits a ranging signal 2 carrying the device ID of the electronic device 1.

S6B05: distance 2 is determined based on the received signal strength indication of ranging signal 2.

The electronic device 1 receives the ranging signal 2 and determines the distance 2 based on the RSSI.

S6B06: the smaller of the distances 1 and 2 is determined to be the distance between the two electronic devices.

The electronic device 1 and the electronic device 2 exchange the distance 1 and the distance 2 by connecting, and then the smaller value of the distance 1 and the distance 2 can be determined as the distance between the two electronic devices.

It should be noted that the content shown in fig. 6A and fig. 6B is only an exemplary illustration of bluetooth ranging, and is not limited to a specific implementation of bluetooth ranging, and any ranging implementation based on bluetooth protocol belongs to bluetooth ranging in the embodiments of the present application. For example, the first electronic device may send a ranging request to the second electronic device based on the connection, and the second electronic device may send ranging signal 1 after receiving the ranging request. The first electronic device determines distance 1 as the distance between the two electronic devices based on the RSSI of ranging signal 1.

As shown in fig. 6C, in the case where the distance between two electronic devices is smaller than the distance 1, the RSSI and the distance are substantially linear, and the change in the RSSI with the distance is smooth. When the value of RSSI is greater than the received signal strength indication value 1, i.e., the distance between two electronic devices is greater than the distance 1, the rate of change of RSSI is too large, and slight jitter of RSSI may cause a large change in distance and a large error.

Alternatively, in some embodiments of the present application, when the distance obtained by bluetooth ranging is greater than distance 1, the error of bluetooth ranging is considered to be too large, which is greater than the error threshold of all service requirements. For example, the distance 1 is 35cm.

As shown in fig. 7, the ultrasonic ranging may include step S701, step S702, step S703, step S704.

S701: a connection is established and a device ID is negotiated.

The connection may be established by WIFI, bluetooth, near Field Communication (NFC), zigbee, and the like, which is not limited herein.

It is worth noting that bluetooth ranging may use the same device ID as ultrasonic ranging.

S702: an ultrasonic signal 1 carrying the device ID of the electronic device 2 is transmitted.

The electronic device 1 transmits an ultrasonic signal 1 carrying the device ID of the electronic device 2.

S703: an ultrasonic signal 2 carrying the device ID of the electronic device 1 and processing delay is transmitted.

The electronic device 2 transmits an ultrasonic signal 2 carrying the device ID of the electronic device 2 with processing delay. The processing time delay is the time delay from the time when the electronic device 2 receives the ultrasonic signal 1 to the time when the ultrasonic signal 2 is sent.

S704: distance 1 is determined based on the time interval and the processing delay.

The electronic device 1 determines the distance 1 based on the time interval and the processing delay. The time interval is a time delay from the electronic device 1 to the sending of the ultrasonic signal 1 until the receiving of the ultrasonic signal 2. The electronic device 1 may calculate the transmission delay of the ultrasonic signal based on the time interval and the processing delay, and then determine the distance 1 based on the speed of the ultrasonic signal in space and the transmission delay, where the distance 1 is the distance between two electronic devices.

It should be noted that the content shown in fig. 7 is only an exemplary illustration of the ultrasonic ranging, and does not limit the specific implementation of the ultrasonic ranging, and any ranging mode in the ultrasonic frequency band belongs to the ultrasonic ranging in the embodiment of the present application.

After ultrasonic ranging and bluetooth ranging are introduced, the following describes a specific process of the electronic device executing the ranging method provided by the embodiment of the application under different scenes.

As shown in fig. 8A, the method for performing ranging provided by the embodiment of the present application by using the electronic device provided by the embodiment of the present application may include the following steps:

s801: a connection is established and a device ID is negotiated.

S802: and selecting a Bluetooth ranging mode to perform ranging, and determining a distance 1.

The distance measuring modes supported by the electronic equipment comprise Bluetooth distance measuring and ultrasonic distance measuring. The power consumption of Bluetooth ranging is lower than that of ultrasonic ranging, and the time consumption of Bluetooth ranging is lower than that of ultrasonic ranging. When the distance of the Bluetooth ranging is smaller than the distance threshold value 1, the error of the Bluetooth ranging is smaller than or equal to the ultrasonic ranging; when the distance of the Bluetooth ranging is greater than or equal to the distance threshold value 1, the error of the Bluetooth ranging is greater than the ultrasonic ranging.

Or when the distance determined by the Bluetooth ranging is smaller than the distance threshold value 1, the error of the Bluetooth ranging is smaller than the error threshold value required by the electronic equipment; under the condition that the distance of the Bluetooth ranging is greater than or equal to a distance threshold value 1, the error of the Bluetooth ranging is greater than an error threshold value required by the electronic equipment; and the error of the ultrasonic ranging is always smaller than the error threshold required by the electronic device.

Since the distance between the electronic device 1 and the electronic device 2 is not yet determined after the connection between the electronic device 1 and the electronic device 2 is established, the ranging mode with the lowest power consumption and the shortest time consumption can be selected to perform the ranging, that is, the bluetooth ranging is selected to perform the ranging. The result of the electronic device performing bluetooth ranging is a distance 1.

The bluetooth ranging may refer to the text descriptions corresponding to fig. 6A, fig. 6B, and fig. 6C, which are not repeated here.

S803: it is determined that distance 1 is greater than distance threshold 1.

S804: and selecting an ultrasonic ranging mode to perform ranging, and determining a distance 2.

Since distance 1 is greater than distance threshold 1, the error of bluetooth ranging is greater than ultrasonic ranging. That is, since the distance measurement method with the highest accuracy at the distance 1 is not bluetooth distance measurement but ultrasonic distance measurement, the distance 2 is determined by selecting ultrasonic distance measurement to perform distance measurement based on the above steps S503 and S505. Wherein the distance 2 is the distance between the electronic device 1 and the electronic device 2.

As shown in fig. 8B, the method for performing ranging provided by the embodiment of the present application by using the electronic device provided by the embodiment of the present application may include the following steps:

the descriptions of S801 and S802 are shown in the corresponding text descriptions of fig. 8A, and are not repeated here.

S805: it is determined that the distance 1 is smaller than the distance threshold 1, the distance 1 being the distance between the electronic device 1 and the electronic device 2.

When the distance of the bluetooth ranging is less than the threshold value 1, the error of the bluetooth ranging is less than or equal to the ultrasonic ranging, so based on step S503 and step S504 above, it is determined that the distance 1 is the distance between the electronic device 1 and the electronic device 2.

It should be noted that the ranging process shown in fig. 8A and 8B may be referred to as the first ranging after the connection is established. After the primary ranging is completed, if the electronic device and the second electronic device are not both stationary, the electronic device executes step S506, step S507, step S508, and step S509 in fig. 5, and when the ranging modes supported by the electronic device are bluetooth ranging and ultrasonic ranging, the electronic device executes the ranging modes according to the embodiment of the present application as shown in fig. 9.

S901: and after the first electronic equipment and the second electronic equipment are connected, performing first distance measurement to determine a distance 1.

The method for performing the first ranging after the connection between the first electronic device and the second electronic device may refer to the text descriptions corresponding to fig. 8A and 8B, which are not repeated herein.

The distance measuring modes supported by the first electronic equipment and the second electronic equipment comprise Bluetooth distance measuring and ultrasonic distance measuring.

S902: in response to the first electronic device and/or the second electronic device moving, it is determined whether the distance 1 is less than a distance threshold 1.

In response to the first electronic device and/or the second electronic device moving, it is determined whether the distance 1 is less than a distance threshold 1. If yes, go to step S903; if not, step S905 is performed.

When the distance of the Bluetooth ranging is smaller than the distance threshold value 1, the error of the Bluetooth ranging is smaller than or equal to the ultrasonic ranging; when the distance of the Bluetooth ranging is greater than the distance threshold value 1, the error of the Bluetooth ranging is greater than the ultrasonic ranging.

S903: bluetooth ranging is periodically performed.

Since the distance 1 determined by the first electronic device when performing the first ranging is smaller than the distance threshold 1 and the error of the bluetooth ranging is smaller than or equal to the ultrasonic ranging, the bluetooth ranging can be periodically performed.

S904: and judging whether the distance obtained by Bluetooth ranging is greater than or equal to a distance threshold value 1.

The first electronic device judges whether the distance obtained by Bluetooth ranging is greater than or equal to a distance threshold value 1. If yes, go to step S905; if not, go to step S903.

S905: ultrasonic ranging is periodically performed.

Since the distance obtained by bluetooth ranging or the first ranging is equal to or greater than the distance threshold 1, the error of bluetooth ranging is greater than the error of ultrasonic ranging, and ultrasonic ranging is selectively performed according to the above steps S507, S509. And, since the distance between the first electronic device and/or the second electronic device is varied in the moving process of the first electronic device and/or the second electronic device, the first electronic device periodically performs the ultrasonic ranging.

S906: and judging whether the distance obtained by ultrasonic ranging is greater than or equal to a distance threshold value 1.

After the distance is obtained through ultrasonic ranging each time, whether the distance obtained through ultrasonic ranging is greater than or equal to a distance threshold value 1 is judged. If yes, go to step S905; if not, step S903 is performed.

In consideration of different requirements of different services on distance and error threshold values, the ranging method provided by the embodiment of the application can also adjust the combination of different ranging modes according to different services, thereby simultaneously realizing power consumption reduction and error reduction.

As shown in fig. 10A, S10A1: and after the first electronic equipment and the second electronic equipment are connected, selecting a first ranging mode to perform ranging, determining a first distance, and determining one or more services based on the first distance.

After the first electronic device establishes a connection with the second electronic device, a first ranging mode is selected to perform ranging, and the first distance is determined, which may be described in the text of step S501.

The first electronic device and/or the second electronic device may compare the first distance to a distance upper limit for each service, which is a service that will be created later when the first distance is less than the distance upper limit for a service. Wherein the number of services may be one or more. The upper limit of the distance of the service may be referred to the corresponding text description of table 2, which is not repeated here.

Optionally, in some embodiments of the present application, after each time the first electronic device and/or the second electronic device determine the distance, in a case where an error of a ranging manner of determining the distance is smaller than an error threshold of the service and the distance determined by the ranging manner is smaller than an upper distance limit of the service, the first electronic device and/or the second electronic device correspondingly creates the service and executes an operation corresponding to the service.

Optionally, in some embodiments of the present application, after each time the first electronic device and/or the second electronic device determine the distance, if the distance determined by the ranging manner is greater than the upper distance limit of the service, the first electronic device and/or the second electronic device may log off the service correspondingly.

S10A2: and judging whether the error of the first ranging mode is smaller than an error threshold value.

The first electronic device and/or the second electronic device may determine an error of the first ranging mode and then determine whether the error of the first ranging mode is less than an error threshold. When the number of the services is multiple, the error threshold is the minimum value of the error thresholds of the multiple services; when the number of services is one, the error threshold is the error threshold of the service.

It should be noted that, when the number of services is zero, the error threshold is infinity, and the error of any ranging mode is smaller than the error threshold.

When the error of the first ranging mode is less than the error threshold, executing step S10A3; when it is determined that the error of the first ranging method is equal to or greater than the error threshold, step S10A4 is performed.

S10A3: and executing the operation corresponding to the one or more services.

The first electronic device and/or the second electronic device may run the one or more services and perform operations corresponding to the one or more services.

In the scenario shown in fig. 1A, the service is a multi-screen collaboration service, and the operation corresponding to the service is: the electronic device 3 will adjust the position of the control 101 in the device list, etc. In the scenario shown in fig. 2, the service is a pairing task, and the electronic device 2 initiates a connection request with the bluetooth headset 1. In the scenario shown in fig. 3, the service is a network access capability sharing service, the electronic device 1 and/or the electronic device 2 may create or cancel the network access capability sharing service, adjust the power of the transmitter according to the first distance, and so on. In the scenario shown in fig. 4, the service is a communication sharing service and/or a sms sharing service, and the electronic device 1 and/or the electronic device 2 may create or cancel the communication sharing service and/or the sms sharing service, and display or not display the control 405 and the control 406, etc.

S10A4: and selecting a second ranging mode smaller than the error threshold to perform ranging, determining a second distance, and performing operations corresponding to the one or more services.

Since the error of the first ranging mode is greater than or equal to the error threshold, the distance obtained by the first ranging mode may cause the traffic to fail to operate normally, the second ranging mode smaller than the error threshold is selected to perform ranging, the second distance is determined, and the operation corresponding to the one or more traffic is performed.

The operation corresponding to the one or more services may refer to the corresponding text description in step S10A3, which is not described herein.

Optionally, in some embodiments of the present application, after determining the second distance, the one or more services may be redetermined based on the second distance, and then step S10A4 is repeatedly performed until the determined one or more services on the first electronic device and/or the second electronic device are unchanged.

S10A5: and in response to the movement of the first electronic device and/or the second electronic device, periodically performing ranging in a third ranging manner based on the distance obtained by the last ranging to obtain a third distance.

In response to movement of the first electronic device and/or the second electronic device, the first electronic device and/or the second electronic device periodically perform ranging in a third ranging manner based on the distance obtained by the last ranging to obtain a third distance.

If the last ranging is not available, the third ranging mode is the ranging mode with the lowest power consumption; if the distance obtained by the last distance measurement is larger than the maximum value in the upper distance limits of all the services, the third distance measurement mode is the distance measurement mode with the lowest power consumption.

After determining the third distance, one or more services need to be redetermined, and then a ranging mode with an error smaller than an error threshold of the one or more services is selected, which is equivalent to repeatedly executing step S10A5 until the first electronic device and/or the second electronic device are stationary. The method for redefining one or more services may refer to step S10A1 above, and will not be described herein. In the moving process of the first electronic device and/or the second electronic device, since the distance between the electronic devices may change due to the movement of the first electronic device and/or the second electronic device, the ranging needs to be periodically performed in the third ranging mode and one or more services need to be continuously redetermined.

The method for determining the third ranging method based on the distance determined by the previous ranging may refer to the content shown in fig. 10B.

As shown in fig. 10B, the method for determining the third ranging method based on the distance determined by the previous ranging includes steps S10B1, S10B2, S10B3, and S10B4.

S10B1: one or more services are determined based on the last determined distance.

The method for determining one or more services may refer to step S10A1 above, and will not be described herein.

The one or more services determined in step S10B1 may be different from the one or more services determined in step S10A1, and the first electronic device and/or the second electronic device may also create or cancel the corresponding service.

S10B2: and judging whether the error of the ranging mode with the lowest power consumption is smaller than an error threshold value.

The first electronic device and/or the second electronic device judges whether the error of the ranging mode with the lowest power consumption is smaller than an error threshold value. When the number of the services is multiple, the error threshold is the minimum value of the error thresholds of the multiple services; when the number of services is one, the error threshold is the error threshold of the service. Wherein the one or more services are the services determined in step S10B 1.

If the error of the ranging mode with the lowest power consumption is smaller than the error threshold, executing the step S10B3; if the error of the ranging mode with the lowest power consumption is equal to or greater than the error threshold, step S10B4 is executed.

S10B3: and selecting the ranging mode with the lowest power consumption as the third ranging mode.

The first electronic device and/or the second electronic device selects a ranging mode with the lowest power consumption as a third ranging mode.

S10B4: a ranging mode smaller than the error threshold is selected as the third ranging mode.

The first electronic device and/or the second electronic device selects a ranging mode smaller than the error threshold as a third ranging mode.

The following describes the ranging methods shown in fig. 10A and fig. 10B by taking a service as a network access capability sharing service, and examples of ranging methods supported by the first electronic device and the second electronic device include bluetooth ranging and ultrasonic ranging.

The upper limit of the distance of the internet surfing capability sharing service is 1m, and the error threshold value is 10cm. When the distance between the electronic devices is greater than 35cm, the error of ultrasonic ranging is smaller than that of Bluetooth ranging, and when the distance between the electronic devices is smaller than or equal to 35cm, the error of ultrasonic ranging is greater than or equal to that of Bluetooth ranging. The error of bluetooth ranging increases with increasing distance. When the distance between the electronic devices is greater than 40cm, the error of Bluetooth ranging is greater than or equal to 10cm, the error of ultrasonic ranging is less than 10cm, and the power consumption of ultrasonic ranging is greater than Bluetooth ranging.

It should be noted that the above parameters such as error, power consumption, etc. of bluetooth ranging and ultrasonic ranging are merely exemplary, and the embodiments of the present application are not limited thereto. For example, ultrasonic ranging may also consume less power than bluetooth ranging.

As shown in fig. 11A, the distance between two electronic devices is greater than 100cm at time 0; then, from the time 0 to the time t0, the distance between the two electronic devices is gradually reduced to 100cm; from time t0 to time t1, the distance between the two electronic devices gradually decreases from 100cm to 40cm; from time t1 to time t2, the distance between the two electronic devices gradually decreases from 40cm to 35cm; from time t2 to time t3, the distance between the two electronic devices is less than 35cm; from the time t3 to the time t4, the distance between the two electronic devices is not changed, and the two electronic devices are stationary; from time t4 to time t5, the distance between the two electronic devices increases to 35cm; from time t5 to time t6, the distance between the two electronic devices increases from 35cm to 40cm; from time t6 to time t7, the distance between the two electronic devices increases from 40cm to 100cm; from time t7 to time t8, the distance between the two electronic devices gradually increases; after time t8, the distance between the two electronic devices is unchanged, and the two electronic devices are stationary.

After the first electronic device and the second electronic device establish connection, the first ranging is performed, and it is determined at time 0 that the distance between the two electronic devices is greater than 100cm. After the first electronic device and the second electronic device are connected, the distance between the two electronic devices is determined to be greater than 100cm through Bluetooth ranging.

The distance between two electronic devices is less than 100cm and less than the upper limit of the distance of the internet surfing capability sharing service before the time t1 after the time t0, so that a distance measurement mode meeting the error threshold of the internet surfing capability sharing service needs to be used, namely, the distance between the two electronic devices is measured by using ultrasonic distance measurement.

Before t3 after t1, the first electronic device and/or the second electronic device determine that the ranging mode meeting the error threshold of the internet surfing capability sharing service includes bluetooth ranging and ultrasonic ranging, and then one ranging mode can be randomly selected to perform ranging. Alternatively, in some embodiments of the present application, bluetooth ranging may be selected because bluetooth ranging consumes less power than ultrasonic ranging. Alternatively, in some embodiments of the present application, a ranging mode with higher accuracy may be selected according to the change of the distance. For example, ultrasonic ranging is selected before time t2 after time t1, and bluetooth ranging is selected before time t3 after time t 2.

And before t4 after t3, the first electronic equipment and the second electronic equipment are stationary, the distance between the two electronic equipment is smaller than 35cm, and the distance measurement mode with the lowest power consumption is selected to perform the distance measurement, namely, the Bluetooth distance measurement is selected to perform the distance measurement.

Before t6 after t4, the first electronic device and/or the second electronic device determine that the ranging mode meeting the error threshold of the internet surfing capability sharing service includes bluetooth ranging and ultrasonic ranging, and then one ranging mode can be randomly selected to perform ranging. Alternatively, in some embodiments of the present application, bluetooth ranging may be selected because bluetooth ranging consumes less power than ultrasonic ranging. Alternatively, in some embodiments of the present application, a ranging mode with higher accuracy may be selected according to the change of the distance. For example, ultrasonic ranging is selected before time t6 after time t5, and bluetooth ranging is selected before time t5 after time t 4.

The distance between two electronic devices is less than 100cm and less than the upper limit of the distance of the internet surfing capability sharing service before the time t7 after the time t6, so that a distance measurement mode meeting the error threshold of the internet surfing capability sharing service needs to be used, namely, the distance between the two electronic devices is measured by using ultrasonic distance measurement.

And before t8 after t7, the distance between the two electronic devices is larger than the upper limit of the distance of the internet surfing capability sharing service, and the two electronic devices are not stationary, so that Bluetooth ranging is periodically executed.

After the time t8, because the distance between the two electronic devices is greater than the upper limit of the distance of the internet surfing capability sharing service, and the two electronic devices are stationary, the Bluetooth ranging is performed once.

It is worth to be noted that, under the condition that the first electronic device and the second electronic device are both stationary, distance measurement is only performed once; in the case where the first electronic device and the second electronic device are not both stationary, ranging is periodically performed.

The first electronic device and the second electronic device may also perform ranging with reference to the method shown in fig. 9, as shown in fig. 11B.

Unlike what is shown in fig. 11A, the ranging method described in fig. 11B does not consider the case of the upper range limit of traffic and the error threshold of traffic.
