Description

TECHNICAL FIELD



[0001] The present invention relates to the communications field, and in particular, to a communication event notification method, an apparatus, and a system.

BACKGROUND



[0002] The development of communications technologies has made mobile phone communication an indispensable part of people's routine life, for instance, all information exchanges between one user and another can be implemented by means of mobile phone communication. Generally, in some indoor environments, because of being away from a mobile phone, or other like cases, a user often misses a communication event such as a call or a short message. Consequently, the user cannot exchange information with another user.

[0003] In the prior art, when a user's mobile phone receives a communication event, a function of notifying the user may be generally implemented by using two methods. In one aspect, a smart television may be used to notify the user of a communication event received by the user's mobile phone. Optionally, a connection between the smart television and the mobile phone may be implemented by using a wireless communications technology. When receiving a communication event, the mobile phone may send the communication event to the smart television by using the wireless communications technology, so that the smart television can present the communication event to the user to notify the user of the communication event received by the user's mobile phone. In the other aspect, a wearable device may be used to notify the user of a communication event received by the user's mobile phone. Optionally, a connection between the wearable device and the mobile phone may be implemented by using a Bluetooth technology. When receiving a communication event, the mobile phone may send the communication event to the wearable device by using the Bluetooth technology, so that the wearable device can present the communication event to the user to notify the user of the communication event received by the user's mobile phone.

[0004] However, in one aspect, if the smart television is used to notify the user of the communication event received by the user's mobile phone, due to a limitation of a position where the smart television is placed, the user cannot see a notification of the communication event when the user is not near the smart television; therefore, a function of notifying the user by the smart television is subject to a geographical restriction. In the other aspect, if the wearable device is used to notify the user of the communication event received by the user's mobile phone, due to a limited effective distance of the used Bluetooth technology, the user cannot receive the notification of the communication event when a distance between the user and the mobile phone is greater than an effective distance of Bluetooth transmission; therefore, a function of notifying the user by the wearable device is subject to a distance restriction.

[0080] The central device separately acquires the identifiers of the candidate bridge devices and the capability information of the candidate bridge devices, that is, the central device discovers the candidate bridge devices in the local network, that is, acquires the identifiers of the candidate bridge devices; and acquires the capability information of the candidate bridge devices, to determine capabilities of the bridge devices separately.

[0081] It should be noted that capability information of a bridge device may include service information, a presenting capability, decoding information, resolution, and the like.

  2. (2). The central device sends an mDNS (multicastDNS, multicast DNS) broadcast message to acquire the identifier of the bridge device and the capability information of the bridge device directly.


[0083] It should be noted that when the central device acquires the identifiers of the candidate bridge devices and the capability information of the candidate bridge devices in the manner (1), the central device needs to be a central device having a UPnP (Universal Plug and Play, Universal Plug and Play) function. Optionally, the central device may be a central device in which UPnP protocols or a UPnP application is installed.

[0084] UPnP standards implement media sharing application in the local network, and define three entities:
  1. (1). Media Renderer, that is, a media presenting device, which can play media content designated by a control-point device, where the media presenting device may be a device such as a TV;

[0090] Optionally, the capability information of the candidate bridge devices includes service information of the candidate bridge devices. Therefore, the central device can determine, from the candidate bridge devices according to the service information of the candidate bridge devices, the identifiers of the multiple candidate bridge devices having the information reporting service, that is, determine the multiple candidate bridge devices having the information reporting service, where the identifiers of the multiple candidate bridge devices are corresponding to the multiple candidate bridge devices.

[0091] It should be noted that the multiple candidate bridge devices have the information reporting service means that each candidate bridge device in the multiple candidate bridge devices can report acquired information to the central device.

[0092] S403. The central device separately subscribes to the information reporting service of the multiple candidate bridge devices according to the identifiers of the multiple candidate bridge devices.

[0093] After the central device determines, from the candidate bridge devices according to the capability information of the candidate bridge devices, the identifiers of the multiple candidate bridge devices having the information reporting service, the central device separately subscribes to a signal strength reporting service of the multiple bridge devices according to the identifiers of the multiple bridge devices.

[0096] S4031. The central device sends a request message separately to the multiple candidate bridge devices according to the identifiers of the multiple bridge devices, where the request message is used to request the multiple candidate bridge devices to provide the information reporting service separately, where the information reporting service is: a position information reporting service, a transmission signal strength reporting service, or a position information reporting service and a transmission signal strength reporting service, where the information reporting service is the position information reporting service, and parameter information includes at least one of: an actual distance between the candidate bridge device and a wearable device, and position information of the candidate bridge device and position information of the wearable device; or the information reporting service is the transmission signal strength reporting service, and parameter information includes at least one of: a converted distance between the candidate bridge device and a wearable device, and transmission signal strength between the candidate bridge device and the wearable device; or the information reporting service is the position information reporting service and the transmission signal strength reporting service, and parameter information includes: an actual distance between the candidate bridge device and a wearable device, position information of the candidate bridge device and position information of the wearable device, and at least one of: a converted distance between the candidate bridge device and the wearable device, and transmission signal strength between the candidate bridge device and the wearable device.

[0097] It can be understood that the central device sends the request message separately to the multiple candidate bridge devices according to the identifiers of the multiple candidate bridge devices, that is, the multiple candidate bridge devices receive the request message sent separately by the central device, where the request message is used to request each bridge device in the multiple candidate bridge devices to provide the information reporting service, that is, the request message is used to request the multiple candidate bridge devices to provide the information reporting service separately.

[0098] It should be noted that the wearable device is a smart wearable device such as glasses, gloves, a watch, jewelry, apparel, or shoes. Optionally, current wearable devices include: a smartwatch, a smartband, a head-mounted display, smart shoes, an electronic drum machine T-shirt, and the like. The wearable device in this embodiment of the present invention may be a smart device that can be carried with a user and can send a first wireless broadcast signal.

[0099] It should be noted that in this embodiment of the present invention, a correspondence between a central device and a wearable device is also carried in the request message; the central device is paired with the wearable device according to the correspondence; and optionally, the central device may be paired with the wearable device by using a wireless technology, such as Bluetooth. This embodiment of the present invention constitutes no limitation on a manner of the correspondence.

[0100] Optionally, the correspondence between a central device and a wearable device may include that: one central device may be corresponding to multiple wearable devices of a user, that is, the central device is corresponding to the wearable device.

[0101] S4032. The multiple candidate bridge devices separately send a response message corresponding to the request message to the central device.

[0102] After the central device sends the request message separately to the multiple candidate bridge devices according to the identifiers of the multiple bridge devices, each candidate bridge device in the multiple candidate bridge devices sends the response message corresponding to the request message to the central device, that is, the central device subscribes to the information reporting service.

[0103] S404. The wearable device sends a first transmission signal to the multiple candidate bridge devices, where an identifier of the wearable device is carried in the first transmission signal.

[0105] Optionally, the first transmission signal may be a first Bluetooth broadcast signal.

[0106] It should be noted that because the identifier of the wearable device is carried in the first transmission signal, each candidate bridge device in the multiple candidate bridge devices can report, according to the identifier of the wearable device, signal strength of the first transmission signal to the central device corresponding to the identifier of the wearable device, that is, the central device corresponding to the wearable device.

[0107] Optionally, a manner in which the wearable device sends the first wireless broadcast signal may be periodic, for example, a period is 1 second; or may be aperiodic, that is, intermittent. An optional sending manner depends on an actual situation, which is not limited in this embodiment of the present invention.

[0109] It should be noted that the wearable device sends the first wireless broadcast signal continuously, and time for sending the first wireless broadcast signal is not limited. Wireless communication can be performed between the wearable device and the central device; therefore, the wearable device can send the first wireless broadcast signal when a wireless connection between the wearable device and the central device is disconnected, and can also send the first wireless broadcast signal when the central device and the wearable device are wirelessly connected.

[0110] S405. The multiple candidate bridge devices send a second transmission signal to the wearable device separately, where a message for requesting the wearable device to send the first transmission signal is carried in the second transmission signal.

[0113] Optionally, a manner in which the multiple candidate bridge devices send the second wireless broadcast signal separately may be periodic, for example, a period is 1 second; or may be aperiodic, that is, intermittent.

[0117] Particularly, the multiple candidate bridge devices may acquire the first wireless broadcast signal sent by the wearable device in two manners: acquiring proactively and acquiring passively. Step S404 is a manner in which the multiple candidate bridge devices passively acquire the first wireless broadcast signal sent by the wearable device. Steps S405-S406 is a manner in which the multiple candidate bridge devices proactively acquire the first wireless broadcast signal sent by the wearable device.

[0118] It should be noted that steps S404 and S405-S406 are two parallel steps subsequent to step S403, that is, in this embodiment of the present invention, either step S404 or steps S405-S406 are performed after step S403, which is not limited in the present invention.

[0121] It should be noted that the position information of the wearable device and the transmission signal strength of the transmission signal that are included in the reference information are determined by the candidate bridge device according to the first transmission signal, that is, the first broadcast signal.

[0122] Optionally, each bridge device in the multiple candidate bridge devices measures, according to the first transmission signal, the transmission signal strength of the first transmission signal to determine the transmission signal strength; and each bridge device in the multiple bridge devices reports the position information of the wearable device and the position information of each bridge device in the multiple candidate bridge devices separately to the central device according to the identifier of the wearable device.

[0126] S408. The multiple candidate bridge devices report the reference information to the central device.

[0127] After the multiple candidate bridge devices determine the reference information of the multiple candidate bridge devices according to the first transmission signal, the multiple candidate bridge devices may report the reference information to the central device separately according to the identifier of the wearable device, where the reference information is: the position information of the wearable device, the position information of each bridge device in the multiple candidate bridge devices, and/or the transmission signal strength, where the identifiers of the multiple candidate bridge devices are corresponding to the reported reference information respectively.

[0128] Optionally, each bridge device in the multiple candidate bridge devices may determine, according to an identifier of one wearable device and a correspondence between the wearable device and a central device, an identifier of the central device corresponding to the wearable device. Each bridge device in the multiple candidate bridge devices reports the transmission signal strength of the first transmission signal and the identifier of each bridge device in the multiple candidate bridge devices to the central device according to the identifier of the central device.

[0129] It should be noted that the multiple bridge devices report the reference information as an event to the central device.

[0130] Optionally, the multiple candidate bridge devices may report the transmission signal strength of the first transmission signal and the identifiers of the multiple candidate bridge devices separately to any central device according to the identifier of the wearable device. When a central device acquires the transmission signal strength, reported by any bridge device, of the first transmission signal that is sent by one wearable device, and if the central device is not corresponding to the wearable device, that is, the wearable device is not a wearable device with which the central device is paired, the central device ignores the event, and no processing is performed.

[0131] S409. The central device learns of a communication event.

[0134] Optionally, the user equipment may be an electronic device such as a smartphone, a computer, or a tablet computer, and the central device may be a device that can learn of a communication event, which is not limited in the present invention.

[0135] It should be noted that after the central device learns of the communication event, the multiple candidate bridge devices report the reference information, where the reference information is reported by the multiple candidate bridge devices most recently, that is, step S409 may be performed before step S408 is performed. As such, the present invention constitutes no limitation on a sequence of performing step S408 and step S409.

[0136] Optionally, steps S404-S408 are steps that are performed continuously and circularly in this embodiment of the present invention. Step S409 may be performed at any step between step S404 and step S408, which is not limited in the present invention.

In this embodiment of the present invention, that the central device is corresponding to the wearable device may be that the central device is paired with the wearable device, and this embodiment of the present invention constitutes no limitation on a manner of a correspondence.

[0142] It should be noted that a person skilled in the art may understand that when a distance between the candidate bridge device and the wearable device becomes shorter, the transmission signal strength of the first transmission signal that is received by the candidate bridge device and sent by the wearable device becomes stronger. Therefore, the transmission signal strength of the first transmission signal may also be used to represent a distance between the candidate bridge device and the wearable device.

[0143] It should be noted that after acquiring the reference information of the multiple bridge devices, the central device determines, according to the reference information, parameter information corresponding to the reference information.

That is, the actual distance between the candidate bridge device and the wearable device is determined, by the central device after acquiring the position information of the candidate bridge device and the position information of the wearable device that are reported by the candidate bridge device, according to the position information of the candidate bridge device and the position information of the wearable device; the transmission signal strength between the candidate bridge device and the wearable device is determined by the central device after acquiring information reported by the candidate bridge device; and the converted distance between the candidate bridge device and the wearable device is obtained by the central device through calculation according to the transmission signal strength.

[0148] Optionally, that the central device determines an identifier of at least one bridge device according to parameter information of the multiple candidate bridge devices includes the following several situations:

[0149] (1). The central device determines an identifier of at least one bridge device whose actual distance from the wearable device is shortest.

[0150] After the central device learns of the communication event, the central device determines the identifier of the at least one bridge device whose distance from the wearable device is shortest, where the identifier of the at least one bridge device is determined by the central device most recently.

[0151] Optionally, the central device acquires the actual distance between each bridge device in the multiple candidate bridge devices and the wearable device separately according to the acquired position information of each bridge device in the multiple candidate bridge devices and the acquired position information of the wearable device, and determines the identifier of the at least one bridge device whose actual distance from the wearable device is shortest.

[0152] It should be noted that the central device may determine the identifier of the at least one bridge device before the central device learns of the communication event or after the central device learns of the communication event, which is not limited in the present invention. That is, the central device determines the identifier of the at least one bridge device, and after the central device learns of the communication event, the central device acquires an identifier, determined most recently, of at least one bridge device; alternatively, after the central device acquires the communication event, the central device determines the identifier of the at least one bridge device and acquires the identifier of the at least one bridge device.

[0153] (2). The central device determines an identifier of at least one bridge device whose converted distance from the wearable device is shortest.

[0154] After the central device learns of the communication event, the central device determines the identifier of the at least one bridge device whose converted distance from the wearable device is shortest, where the identifier of the at least one bridge device is determined by the central device most recently.

[0155] Optionally, that the central device determines an identifier of at least one bridge device includes that: the central device separately calculates the converted distance between each bridge device in the multiple candidate bridge devices and the wearable device according to the acquired identifiers of the multiple candidate bridge devices and the transmission signal strength reported separately by the multiple candidate bridge devices, and determines the identifier of the at least one bridge device whose converted distance from the wearable device is shortest, where the transmission signal strength reported separately by the multiple candidate bridge devices is the signal strength of the first transmission signal that is received separately by the multiple candidate bridge devices and is sent by the wearable device.

[0156] It should be noted that the central device may determine the identifier of the at least one bridge device before the central device learns of the communication event or after the central device learns of the communication event, which is not limited in the present invention. That is, the central device determines the identifier of the at least one bridge device, and after the central device learns of the communication event, the central device acquires an identifier, determined most recently, of at least one bridge device; alternatively, after the central device learns of the communication event, the central device determines the identifier of the at least one bridge device and acquires the identifier of the at least one bridge device.

[0157] Optionally, the central device calculates the converted distance between each bridge device in the multiple candidate bridge devices and the wearable device according to the transmission signal strength reported by each bridge device in the multiple candidate bridge devices, where the converted distance may be obtained by using a calculation formula.

[0158] For example, the calculation formula may be a signal free space attenuation formula, or may be another formula by which the distance can be calculated according to a signal. Using the signal free space attenuation formula as an example, one manifestation form of the signal free space attenuation formula is: P_RX=P_TX/d^n, where P_RX represents receive power, a unit of which is W/mW (watt/milliwatt), P_TX represents transmit power, a unit of which is W/mW, d represents a distance, a unit of which is m (meter), and n is an integer parameter, a value of which may be between 2-6.

[0159] Illustratively, signal strength, reported by a television, of a first wireless broadcast signal sent by a wearable device 1 is 50dBM (decibel relative to one milliwatt); transmission signal strength, reported by a refrigerator, of the first wireless broadcast signal sent by the wearable device 1 is 40dBM; and transmission signal strength, reported by a microwave oven, of the first wireless broadcast signal sent by the wearable device 1 is 60dBM. The wearable device 1 is paired with a central device 1 by using Bluetooth; a converted distance between the television and the wearable device 1, a converted distance between the refrigerator and the wearable device 1, and a converted distance between the microwave oven and the wearable device 1 are calculated by using a calculation formula between transmission signal strength and a distance; and then, the central device 1 compares the converted distances between the wearable device 1 and the television, the refrigerator, and the microwave oven separately. The transmission signal strength is inversely proportional to the distance, that is, stronger transmission signal strength indicates a shorter converted distance, and therefore, the central device determines the microwave oven whose converted distance from the wearable device 1 is shortest.

[0160] (3). The central device receives an identifier of at least one bridge device that reports the strongest transmission signal strength of the first transmission signal sent by the wearable device.

[0161] After the central device learns of the communication event, the central device receives the identifier of the at least one bridge device that reports the strongest transmission signal strength of the first transmission signal (the first wireless broadcast signal) sent by the wearable device, where the identifier of the at least one bridge device is determined by the central device most recently.

[0162] Optionally, that the central device determines an identifier of at least one bridge device includes that: the central device determines, after comparing acquired transmission signal strength reported by each bridge device in the multiple candidate bridge devices, an identifier of at least one bridge device corresponding to at least one strongest transmission signal strength, where the at least one bridge device is corresponding to the identifier of the at least one bridge device that reports the at least one strongest transmission signal strength, and the at least one bridge device is a bridge device between which and the wearable device transmission signal strength is strongest.

[0163] Illustratively, signal strength, reported by a television, of a first wireless broadcast signal sent by a wearable device 1 is 50dBM; signal strength, reported by a refrigerator, of the first wireless broadcast signal sent by the wearable device 1 is 40dBM; and signal strength, reported by a microwave oven, of the first wireless broadcast signal sent by the wearable device 1 is 60dBM. The wearable device 1 is paired with a central device 1 by using Bluetooth. With 60>50>40, the central device determines the microwave oven between which and the wearable device 1 transmission signal strength is strongest.

[0164] It should be noted that the central device may determine the identifier of the at least one bridge device before the central device learns of the communication event or after the central device learns of the communication event, which is not limited in the present invention. That is, the central device determines the identifier of the at least one bridge device, and after the central device learns of the communication event, the central device acquires an identifier, determined most recently, of at least one bridge device; alternatively, after the central device learns of the communication event, the central device determines the identifier of the at least one bridge device and acquires the identifier of the at least one bridge device.

[0165] (4). The central device acquires an identifier of at least one bridge device whose actual distance from the wearable device is less than the first preset threshold.

[0166] After the central device learns of the communication event, the central device acquires the identifier of the at least one bridge device whose actual distance from the wearable device is less than the first preset threshold, where the identifier of the at least one bridge device is determined by the central device most recently.

[0167] Optionally, the central device acquires an identifier of at least one bridge device whose actual distance from the wearable device is less than the first preset threshold and that has a presenting capability of presenting an image or presenting an image and a sound, where the identifier of the at least one bridge device is determined by the central device most recently.

[0168] Optionally, the first preset threshold may be 10 meters, and a value of the first preset threshold may be set according to an actual situation, which is not limited in the present invention.

[0169] Preferably, the presenting capability may be a media playback capability, where the media playback capability is a capability of presenting an image or presenting an image and a sound; and may also include a capability of supporting TTS.

[0170] It can be understood that a bridge device having the presenting capability can not only display information, but also play the information by sound; such a bridge device has a better communication event notification capability, thereby improving user experience.

[0171] Optionally, that the central device determines an identifier of at least one bridge device includes that: the central device separately acquires the actual distance between each bridge device in the multiple candidate bridge devices and the wearable device according to the acquired position information of each bridge device in the multiple candidate bridge devices and the acquired position information of the wearable device, such as position coordinates or longitude and latitude, and compares the actual distance between each bridge device in the multiple candidate bridge devices and the wearable device with the first preset threshold, to determine identifiers of m bridge devices whose actual distance from the wearable device is less than the first preset threshold, and select, from the identifiers of the m bridge devices, an identifier of at least one bridge device that has the capability of presenting an image or presenting an image and a sound, and supporting TTS, where m≥1.

[0172] Optionally, the central device separately selects, from the identifiers of the m candidate bridge devices according to presenting capabilities of the multiple candidate bridge devices, the identifier of the at least one bridge device corresponding to the capability of presenting an image or presenting an image and a sound, and supporting TTS.

[0174] It can be understood that in a smart home system, the central device may present, by using at least one bridge device, notification information corresponding to the communication event, and the at least one bridge device is at least one bridge device that is determined by the central device from the candidate bridge device and of which parameter information meets the preset condition, that is, the central device can select at least one bridge device of which the actual distance between the candidate bridge device and the wearable device meets the preset condition; therefore, a problem that a function of notifying a user by a smart television is subject to a geographical restriction and a problem that a function of notifying a user by a wearable device is subject to a distance restriction can be resolved, thereby reducing a risk of communication event notification and improving user experience.

[0175] (5). The central device determines an identifier of at least one bridge device whose converted distance from the wearable device is less than the first preset threshold.

[0176] After the central device learns of the communication event, the central device determines the identifier of the at least one bridge device whose converted distance from the wearable device is less than the first preset threshold, where the identifier of the at least one bridge device is determined by the central device most recently.

[0178] Optionally, the first preset threshold may be 10 meters, and a value of the first preset threshold may be set according to an actual situation, which is not limited in the present invention.

[0179] Preferably, a first media presenting capability may be a media playback capability, where the media playback capability is a capability of presenting a video and audio and supporting TTS (Text To Speech, text to speech), that is, a capability of playing a text by sound.

[0180] It can be understood that a bridge device having the presenting capability can not only display information, but also play the information by sound; such a bridge device has a better communication event notification capability, thereby improving user experience.

[0181] Optionally, that the central device determines an identifier of at least one bridge device includes that: the central device calculates the converted distance between each bridge device in the multiple candidate bridge devices and the wearable device according to the acquired transmission signal strength reported by each bridge device in the multiple candidate bridge devices, and compares the converted distance between each bridge device in the multiple candidate bridge devices and the wearable device with the first preset threshold, to determine identifiers of n bridge devices whose distance from the wearable device is less than the first preset threshold, and select, from the identifiers of the n bridge devices, an identifier of at least one bridge device that has the presenting capability, where n≥1.

[0182] Illustratively, transmission signal strength, reported by a television, of a first wireless broadcast signal sent by a wearable device 1 is 50dBM; transmission signal strength, reported by a refrigerator, of the first wireless broadcast signal sent by the wearable device 1 is 40dBM; and transmission signal strength, reported by a microwave oven, of the first wireless broadcast signal sent by the wearable device 1 is 60dBM. The wearable device 1 is paired with a central device 1 by using Bluetooth; a converted distance between the television and the wearable device 1, a converted distance between the refrigerator and the wearable device 1, and a converted distance between the microwave oven and the wearable device 1 are calculated by using a calculation formula between transmission signal strength and a distance; and then, the central device 1 compares the converted distances between the wearable device 1 and the television, the refrigerator, and the microwave oven separately with the first preset threshold, 10 meters. It is assumed that the converted distance between the television and the wearable device 1 is 9 meters, the converted distance between the refrigerator and the wearable device 1 is 11 meters, and the converted distance between the microwave oven and the wearable device 1 is 5 meters. Because 5 meters are less than 10 meters, 9 meters are less than 10 meters, and 11 meters are greater than 10 meters, the central device determines the television and the microwave whose converted distances from the wearable device 1 are less than the first preset threshold; in addition, the television can present an image and a sound, and the microwave oven can present a sound; therefore, the central device determines, from the television and the microwave oven, that the television is the at least one bridge device having the capability of presenting an image and a sound.

[0183] It should be noted that the central device may determine the identifier of the at least one bridge device before the central device learns of the communication event or after the central device learns of the communication event, which is not limited in the present invention. That is, the central device determines the identifier of the at least one bridge device, and after the central device learns of the communication event, the central device acquires an identifier, determined most recently, of at least one bridge device; alternatively, after the central device learns of the communication event, the central device determines the identifier of the at least one bridge device and acquires the identifier of the at least one bridge device.

[0184] It can be understood that in a smart home system, the central device may present, by using at least one bridge device, notification information corresponding to the communication event, and the at least one bridge device is at least one bridge device that is determined by the central device from the candidate bridge device and of which parameter information meets the preset condition, that is, the central device can select at least one bridge device of which the converted distance between the candidate bridge device and the wearable device meets the preset condition; therefore, a problem that a function of notifying a user by a smart television is subject to a geographical restriction and a problem that a function of notifying a user by a wearable device is subject to a distance restriction can be resolved, thereby reducing a risk of communication event notification and improving user experience.

[0185] (6). The central device determines an identifier of at least one bridge device that reports transmission signal strength, greater than the second preset threshold, of the first transmission signal sent by the wearable device.

[0186] After the central device learns of the communication event, the central device acquires the identifier of the at least one bridge device that reports the transmission signal strength, greater than the second preset threshold, of the first transmission signal, that is, the first wireless broadcast signal, sent by the wearable device, where the identifier of the at least one bridge device is determined by the central device most recently.

[0187] Optionally, the central device determines an identifier of at least one bridge device that reports the signal strength, greater than the second preset threshold, of the first wireless broadcast signal and has a presenting capability of presenting an image or presenting an image and a sound.

[0188] Preferably, the presenting capability may be a media playback capability, where the media playback capability is a capability of presenting a video and audio; and may also include a capability of supporting TTS.

[0189] It can be understood that a bridge device having the presenting capability can not only display information, but also play the information by sound; such a bridge device has a better communication event notification capability, thereby improving user experience.

[0190] Optionally, the central device determines, after comparing each acquired transmission signal strength reported by each bridge device in the multiple candidate bridge devices with the second preset threshold, identifiers of k bridge devices corresponding to transmission signal strength greater than the second preset threshold, and selects, from the identifiers of the k bridge devices, an identifier of at least one bridge device having the capability of presenting an image, or presenting an image and a sound, or supporting TTS, where the at least one bridge device is corresponding to the identifier of the at least one bridge device that reports the transmission signal strength greater than the second preset threshold and that has the foregoing presenting capability, and the at least one bridge device is a bridge device between which and the wearable device transmission signal strength is greater than the second preset threshold, where k≥1.

[0191] Optionally, the second preset threshold may be 45dBM, and a value of the second preset threshold may be set according to an actual situation, which is not limited in the present invention.

[0192] Optionally, the central device separately selects, from the identifiers of the k bridge devices according to presenting capabilities of the multiple candidate bridge devices, the identifier of the at least one bridge device corresponding to the capability of presenting an image, or presenting an image and a sound, or supporting TTS.

[0193] Optionally, the capability information, acquired by the central device, of the multiple candidate bridge devices includes the presenting capabilities of the multiple candidate bridge devices, where the media presenting capability is media playback capability information that can be presented by the bridge device, and the media playback capability information includes supporting a video, audio, and TTS.

[0194] Illustratively, transmission signal strength, reported by a television, of a first wireless broadcast signal sent by a wearable device 1 is 50dBM; transmission signal strength, reported by a refrigerator, of the first wireless broadcast signal sent by the wearable device 1 is 40dBM; and transmission signal strength, reported by a microwave oven, of the first wireless broadcast signal sent by the wearable device 1 is 60dBM. A central device 1 compares the transmission signal strength, reported separately by the television, the refrigerator, and the microwave oven, of the first wireless broadcast signal with the second preset threshold, 45dBM. Because 40dBM is less than 45dBM, 50dBM is greater than 45dBM, and 60dBM is greater than 45dBM, the central device determines the television and the microwave oven that are corresponding to the transmission signal strength greater than the second preset threshold; in addition, the television can present a video and audio, and the microwave oven can present audio; therefore, the central device determines, from the television and the microwave oven, that the television is the at least one bridge device having more presenting capabilities.

[0195] Particularly, the central device may determine the identifier of the at least one bridge device before the central device learns of the communication event or after the central device learns of the communication event, which is not limited in the present invention.

The geographical scope may refer to a house or an area, and may be set according to an actual situation, which is not limited in the present invention.

[0199] Optionally, the position information of the candidate bridge device and the position information of the wearable device may be position coordinates of the candidate bridge device and position coordinates of the wearable device; or may be longitude and latitude of the candidate bridge device and longitude and latitude of the wearable device; or may further be other information that can represent positions of the candidate bridge device and the wearable device, which is not limited in the present invention.

[0200] Optionally, when it is met that: the actual distance meets the first preset condition, the transmission signal strength meets the second preset condition, and the presenting capability meets the fourth preset condition; or the converted distance meets the first preset condition, the transmission signal strength meets the second preset condition, and the presenting capability meets the fourth preset condition; or the actual distance or the converted distance meets the first preset condition, the transmission signal strength meets the second preset condition, and the presenting capability meets the fourth preset condition; or the actual distance meets the first preset condition, the position information of the candidate bridge device and the position information of the wearable device meet the third preset condition, and the presenting capability meets the fourth preset condition; or the converted distance meets the first preset condition, the position information of the candidate bridge device and the position information of the wearable device meet the third preset condition, and the presenting capability meets the fourth preset condition, with reference to the foregoing situations (1), (2), (3), (4), (5), (6), and (7), that is, when at least one of that: the actual distance or the converted distance meets the first preset condition, the position information of the candidate bridge device and the position information of the wearable device meet the third preset condition, the transmission signal strength meets the second preset condition is met; and the presenting capability meets the fourth preset condition, the central device determines an identifier of at least one corresponding bridge device.
