The terminology used herein is for the purpose of describing embodiments of the present application only and is not intended to be limiting of the application.

The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

Fig. 1 is a device architecture diagram of a device wake-up scheme in a distributed scenario provided in scheme 1, and as shown in fig. 1, a user equipment may include one or more processors (only one is shown in the figure) and a communication device.

The processor may run an operating system of the user equipment, such as Android, iOS, windows os, Liunix, hong meng operating systems, and the like. The processor may run a specific application. In the scheme 1, a processor is configured with a processing module AP, and the processor executes a device wake-up scheme in a distributed scenario by running an application APP of the processing module AP. The communication device is configured with a short-range communication module BT for performing bluetooth low-power communication.

The processing module AP can be divided into several modules by adopting a layered architecture, each module having a clear role and division of labor. The modules communicate with each other through software interfaces. In the scheme 1, the processor runs an Android system, and the Android system is divided into four modules, which are an application module APP, a software architecture module FW, a protocol stack module HAL (HAL for short), and a Kernel module KEL (KEL for short) from top to bottom.

The application program module APP comprises a series of application program units such as setting, sharing, connecting and waking up, and provides a data interface for publishing tasks and subscribing services.

The software architecture module FW provides an application programming interface and a programming architecture for the application unit of the application module APP. The software architecture module FW includes a bluetooth architecture including some predefined short-range communication functions, such as a BLE broadcast function and a BLE scan function, and an architecture manager.

The protocol stack module HAL provides a uniform access interface for different hardware devices. The protocol stack module HAL comprises the bluetooth protocol stack and other protocol services.

The kernel module KEL is a layer between hardware and software. The kernel module at least includes various drivers, such as Universal Asynchronous Receiver Transmitter (UART).

The short-distance communication module BT performs asynchronous data receiving and transmitting transmission with the processing module AP through the UART interface to realize a short-distance communication function. The UART interface is a general serial data bus for asynchronous communication, which may be a bidirectional communication bus that converts data to be transmitted between serial communication and parallel communication. Short-range communications, including at least any of the various implementations of the existing bluetooth standard, including bluetooth low energy, future implementations of the bluetooth standard, and the like.

The short-range communication module BT includes a channel switching module and an internal logic module. The channel switching module carries out asynchronous scanning and sending of data through a UART interface and carries out short-distance data transmission. The internal logic module comprises a plurality of filters, and the filters are used for filtering short-distance communication scanning results and transmitting broadcast parameters meeting requirements in the scanning results to the processing module AP through the channel switching module; or filtering the downlink broadcast parameters of the processing module AP received by the channel switching module, and broadcasting the data meeting the requirements.

In the device architecture shown in fig. 1, a data transmission path is that a data interface is started in an application module APP, the data interface calls a bluetooth architecture, a bluetooth driver of a kernel module KEL is called through a bluetooth protocol of a protocol stack, the bluetooth driver starts a short-distance communication module BT through a UART interface, and the short-distance communication module BT performs BLE broadcasting according to broadcasting parameters and issues BLE communication services; the short-distance communication module BT performs BLE scanning to receive BLE subscription services of other user equipment.

Fig. 2 is a flowchart of waking up a sleeping device through short-range communication in a distributed scenario. According to the EMUI10.1 version, in a distributed scene, the device A and the at least one device B are automatically networked before a service request, and the device A can directly obtain a list of the at least one device B trusted by the same account on line when the service request is carried out. Device a periodically refreshes the list to learn the presence status of online device B in the list.

In fig. 2, the processing module AP1 of the device a with a bright screen executes a start broadcast instruction of the application APP1, and BLE broadcasting is performed through the short-range communication module BT 1; the processing module AP2 of at least one device B scans the broadcast message to the device a through the short-range communication module BT2 during the start scanning instruction process of the application APP2, reports the broadcast message to the processing module AP2, and processes the online scanning result by the application APP 2.

Device a sends a message packet to at least one device B every 5min, and then at least one device B, whether dormant or not, needs to reply to the message indicating presence (proximity) in response, and no response upon timeout indicates absence. In this scheme, if it is necessary for device a to discover device B, device a continues to perform BLE communication broadcast, device B performs BLE scanning, and device B responds and replies to the message broadcast by device a to indicate that device B is online and confirms that device a discovers device B. Or, the user manually starts the device B to always perform BLE communication scanning, and when the device a performs BLE communication broadcasting, the device B scans the broadcast message of the device a, replies the broadcast message, which indicates that the device B is online, and confirms that the device a finds the device B.

The reply device a may be implemented after the short-range communication module BT2 in the sleep state wakes up the processing module AP 2.

According to the scheme, user discovery and connection among user equipment trusted by the same account can be realized, and the short-distance communication module BT carries out short-distance communication according to a short-distance communication task issued by the processing module AP.

The above scheme has at least the disadvantages that the communication task executed by the device B and the subscription service receiving need to be processed and executed by the processing module AP, which causes the processing module AP to be periodically waken up, resulting in a certain increase in power consumption, and the increase in the power consumption of the whole device, and the increase in the peripheral online devices also causes the power consumption of the whole device to be increased doubly.

Fig. 3 is a flowchart of the short-range communication bidirectional broadcast provided by scheme 2. According to the scheme, mutual discovery between the devices is realized by performing bidirectional broadcasting between the device A and the device B. As shown in fig. 3, when device a needs to discover device B, device a initiates a short-range communication broadcast and scans. Device B is always in scan mode. Device B finds the broadcast of device a by scanning and then responds to device a by issuing broadcast information via short-range communication. The broadcast information responded by the device B comprises a local device name, a user nickname, a local telephone number, a security abstract and the like. The device A obtains the broadcast information responded by the device B through short-distance communication scanning, displays the device name, the user nickname and the telephone number of the device B, searches the head portrait of the device B on the local or cloud through the mark of the device B, and displays the head portrait to the user. The device A is connected with the device B through short-distance communication to provide a data path for the subsequent service.

At least one disadvantage in the short-range communication two-way broadcast provided in fig. 3 is that device B does not perceive the occurrence of this condition after device a discovers device B, and thus device B broadcasts all the time, resulting in increased power consumption by device B. If there are more devices around the device that want to discover device B, the power consumption of device B may multiply as the number of devices around increases. If the device a or the device B in this scheme is a sleeping device, the processing module AP also needs to be woken up to achieve the purpose of mutual discovery between the devices, so that the problem of power consumption increase of the processor AP which is periodically woken up exists.

Based on the defects of the discovery mechanisms of the scheme 1 and the scheme 2, which cause large power consumption of the device, one embodiment of the application provides the user equipment, which can drive the short-distance communication device to execute the short-distance communication task through the intelligent sensing device under the condition that the processor is in a sleep state. The device is additionally provided with an intelligent sensing device on the basis of the device architecture provided by the figure 1.

Among them, the smart sensor hub (Sensorhub) is a solution based on a combination of software and hardware on a low power consumption MCU and a lightweight RTOS operating system, and its main function is to connect and process data from various sensor devices.

Fig. 7(a) is a schematic diagram of a device discovery method applied to a mobile phone a and a television TV according to an embodiment of the present application. As shown in fig. 7(a), taking a first user equipment with a mobile phone a as a dormant state and taking a television TV with bluetooth as a second user equipment as an example, there is a mobile phone a in the dormant state around the television TV, wherein the mobile phone a has the architecture and functions as shown in fig. 4, and comprises a processing module AP, a smart sensor module SH and a short-range communication module BT. When the processing module AP of the mobile phone a is in the sleep state, the short-distance communication module BT and the smart sensor module SH of the mobile phone a are always in the running state. When a television TV needs to find surrounding devices which can perform short-distance communication, the method can be realized by the following steps:

s701, the television TV initiates online detection, broadcasts a message packet M1, and inquires whether the mobile phone A is around. The broadcast parameters carried by the message packet M1 at least include a local device ID, a timing duration and a broadcast time. The broadcast implementation thereof refers to S6021-S6023, which are not described in detail here.

S702, the short-range communication module BT of the handset a in the dormant state reports the received message packet M1 to the smart sensor module SH. After receiving the message packet M1, the intelligent sensing module SH performs online response; the message packet M1 is replied to by broadcasting a message packet M2 through short-range communication, wherein the broadcast parameters of the message packet M2 include at least the local device ID, the target device 1.

In some embodiments, an aggregated processing manner may also be adopted to broadcast a message packet including two or more ue identities, and reply to online query requests of two or more ues at the same time. Specifically, the smart sensor module SH acquires at least one message packet M5 received through scanning before instructing the short-range communication device to broadcast the second message according to the broadcast parameters, the at least one message packet M5 being broadcast by at least one third user equipment, respectively; each message bundle M5 includes an identification of a user device. After receiving the message packet M5, the smart sensor module SH replies to the second user device and at least one third user device together with a message packet M2, and the identifier of each third user device in the message packet M2 is the target device for the reply.

Fig. 7(b) is a schematic diagram of a device discovery method applied to a mobile phone a and multiple television TVs according to an embodiment of the present application. As shown in fig. 7(b), at least one third user device exists, the third user device takes the second TV2 with bluetooth as an example, and the second TV2 with bluetooth needs to find surrounding devices capable of short-distance communication, which is implemented by the following steps:

s701', two TV1 and TV2 with bluetooth respectively initiate online inquiry, wherein the TV1 broadcasts a message package M1 through short-range communication to inquire whether the handset a is around; the TV2 broadcasts a message packet M5 via short-range communication, the message packet M5 including at least one second TV identification. Message bundle M5 is denoted as the fifth message.

S702', the short-distance communication module BT of the mobile phone A in the dormant state reports the received message packet M1 and the message packet M5 to the intelligent sensing module SH respectively, and the intelligent sensing module SH analyzes the message packet M1 and the message packet M5 respectively and stores the identifier of the TV1 and the identifier of the TV 2.

S703', for the message bundle M1 and the message bundle M5, the smart sensor module SH uses an aggregation processing method to edit a message bundle M2, and downlink the message bundle M2 to the short-range communication module BT. The message packet M2 carries both the TV1 id and the TV2 id.

S704', the short-range communication module BT broadcasts the message package M2 while responding to the TV1 and the TV 2.

Specifically, the processing mode of the aggregated message packet M2 is to read the broadcast parameters parsed by the message packet M1 and the message packet M5 from the sensor shared driving unit 403, where the broadcast parameters include the identifier of the TV1 and the identifier of the TV2, and the communication filtering unit 421 performs aggregation processing on the identifier of the TV1 and the identifier of the TV2 to generate a message packet M2. The broadcast parameters of the message bundle M2 include at least a message type, a local device ID, target device 1, and target device 2. Where target device 1 and target device 2 are an identification of television TV1 and an identification of television TV2, respectively. The smart sensor module SH feeds a message packet M2 into the short-range communication module BT, which broadcasts the message packet M2 in response to the TV1 and the TV 2.

For the online query requests of more than two user equipments, under the condition that the processor of the handset a is dormant, the same aggregation processing mode can be adopted to reply to more than two user equipments simultaneously through one message packet M2.

The method for discovering the dormant device provided by the embodiment of fig. 7(b) is applied to discover the dormant device, and in the dormant state of the mobile phone a, the intelligent sensing module SH broadcasts a message including two or more user device identifications in a polymerization processing mode, and replies online query requests of the two or more user devices simultaneously, so that the user devices can acquire lists of the online user devices in each accessible range and obtain link establishment information during the dormant period, and discover and maintain the online state with a plurality of online user devices.

In the process of discovering the dormant device and maintaining the online state, the short-distance communication time of different user equipment in a bright screen state around one dormant device is not synchronous, and the disorder of the time axis causes the time for the user equipment to discover the dormant device by broadcasting to increase irregularly, so that the power consumption is increased. In the process of discovering and maintaining the online state of the dormant device by using short-distance communication broadcast, all user equipment in a bright screen state around the dormant device needs to appoint the frequency and the opportunity of short-distance communication in a networking cluster, and broadcast and scanning tasks are executed in a unified short-distance communication time interval. The short-range communication time interval is a communication/synchronization window.

Fig. 8 is a schematic diagram of a task timing window divided by short-range communication performed by a user equipment. As shown in fig. 8, the task of short-range communication of the user equipment is divided into a communication/synchronization window and a discovery window in time series. The communication/synchronization window is used for the user equipment with the same pace in the cluster to perform broadcasting and scanning in the time interval, perform short-distance communication handshake and complete the task of mutual discovery. And setting the time interval from the end of the communication/synchronization window to the start of the next communication/synchronization window as a discovery window. The discovery window is used for randomly broadcasting the inquiry information and discovering the user equipment with inconsistent outside cluster pace.

For different user equipments in the bright screen state, respective communication/synchronization windows are aligned to a uniform time interval, and it is also necessary to consider that the sensitivity of power consumption, broadcast randomness and address of the different user equipments are different, and these factors may affect the frequency and timing of short-distance communication. For example, when inquiring surrounding user equipment, a television TV is often connected with an external power supply, the electric quantity of the television TV can be taken at any time, the requirement on power consumption sensitivity is low, and the short-distance communication frequency of the television TV can be set to be scanned/broadcast once every 1 minute; the battery power of the mobile phone is limited, and the requirement on power consumption sensitivity is higher, so that the broadcasting frequency of the short-distance communication broadcast of the mobile phone is lower, and the short-distance communication broadcast can be set to be scanned/broadcast once every 5 minutes; PAD sensitivity to power consumption requires a power consumption intermediate between that of a mobile phone and a television TV, which can be scanned/broadcast every 3 minutes. Meanwhile, the address of the user equipment is related to the distance of the short-distance communication, and the power consumption, frequency and opportunity of the short-distance communication are also influenced.

In view of the above-mentioned factors affecting the frequency and timing of short-range communication, in one embodiment of the present application, a value of a device weight is set for each user equipment, and the device weight DW is defined as follows:

DW＝dT*2¹²+Pcons*2⁹+RF*2⁴+MAC[1]*2²+MAC[0]；

dT is the value of the set user equipment model, for example, dT of the handset is 1, dT of the tv is 2, dT of the PAD is 3, and so on. Pcons is a value of power consumption sensitivity, and is related to the user equipment model, for example, Pcons for a handset is 0.7, Pcons for a television is 0.2, Pcons for a PAD is 0.4, and so on. RF is a set random factor. MAC is the device address, 6 bits of data, MAC [0] is the first digit of the device address, MAC [1] is the second digit of the device address.

In order to reduce power consumption during querying of the user equipment in the bright screen state, time intervals of communication/synchronization windows of a plurality of bright screen user equipments are aligned, and a broadcast weight may be set for each user equipment, wherein a value of the broadcast weight is default to a value of a device weight of the local equipment. Within an accessible range, each user equipment broadcasts the maximum value of the broadcast weights of all the surrounding user equipment known by the user equipment along with the message packet M6, and after receiving the message packet M6, the user equipment in the bright screen state adjusts the frequency and the opportunity of broadcasting/scanning along with the equipment with the maximum broadcast weight, so that the time intervals of the communication/synchronization window and the communication/synchronization window of the equipment with the maximum broadcast weight are aligned, short-distance communication is carried out in the aligned communication/synchronization window, synchronous communication is achieved, the time for discovering each other with the sleeping equipment is shortened, and the power consumption is reduced. The message packet M6 may be denoted as a sixth message for agreeing on the frequency and timing of short-range communication.

Based on the above concept, an embodiment of the present application provides a device discovery method, which synchronizes the frequency and the timing of sending a first message by a plurality of bright-screen devices after the plurality of bright-screen devices discover a sleeping device and other online user devices within the reach.

Taking two bright screen devices as an example, on the basis of the foregoing embodiment, during the processing module AP is in a sleep state, the first user equipment receives the short-distance communication parameters from the APP, and further includes a second broadcast weight, a second broadcast time, and a second timing duration, where the second broadcast time and the second timing duration correspond to the second broadcast weight; (ii) a The first message further comprises a first broadcast weight, a first broadcast time and a first timing duration; wherein the first broadcast time and the first timing length correspond to a first broadcast weight. The smart sensor module SH1 also performs: acquiring a fifth message broadcast by at least one third user equipment received through scanning; the fifth message further comprises a third broadcast weight, a third broadcast time and a third timing duration; wherein the third broadcast time and the third timing duration correspond to a third broadcast weight; comparing the values of the first broadcast weight, the second broadcast weight and the third broadcast weight to obtain the maximum broadcast weight; instructing the short-range communication device to broadcast a sixth message according to the short-range communication broadcast parameters within a time range in which the first broadcast time is a first timing length, in a case where the maximum broadcast weight is the first broadcast weight; instructing the short-range communication device to broadcast a sixth message according to the short-range communication broadcast parameter within a time range in which the third broadcast time is a third timing duration, in a case where the maximum broadcast weight is the third broadcast weight; the sixth message comprises the maximum broadcast weight, the synchronous broadcast time and the synchronous timing duration; wherein the synchronized broadcast time and the same timing duration are the values of the broadcast time and the timing duration corresponding to the maximum broadcast weight; the sixth message is used for spreading the maximum broadcast weight, so that the broadcast time and the timing duration of the short-distance communication of the three user equipment are consistent, and the frequency and the opportunity of the synchronous short-distance communication are realized. This is further illustrated by fig. 9.

Specifically, the first ue scans different message packets M1 sent by n-1 ues, the communication analysis unit 422 respectively parses each message packet M1, obtains the identifier, broadcast weight, timing duration, and broadcast time of each device carried in each message packet M1, processes the identifier, broadcast weight, timing duration, and broadcast time of each ue obtained by parsing each message packet M1, and sends the processed identifier, broadcast weight, timing duration, and broadcast time to the sensor sharing driver unit 403 for storage, the communication filter unit 421 determines the maximum broadcast weight for the n broadcast weights stored in the sensor sharing driver unit 403, edits the corresponding message packet M6 according to the maximum broadcast weight, the maximum broadcast weight W in the message packet M6 is the maximum value among the n broadcast weights, the timing duration is the timing duration of the device corresponding to the maximum broadcast weight, and the broadcast time is the broadcast time of the device corresponding to the maximum broadcast weight, the target device comprises an identification of n-1 target devices.

The message packet M6 is broadcasted through the short-distance communication module, so that the third user equipment with the broadcast weight less than the maximum broadcast weight can know the timing duration and the broadcast time of the user equipment with the maximum broadcast weight, and the third user equipment aligns the broadcast timing duration and the broadcast time with the timing duration and the broadcast time corresponding to the maximum broadcast weight, thereby achieving the purpose of synchronously broadcasting and scanning a plurality of third user equipment in a bright screen state.
