Description

Technical Field

[0001] The present application relates to the field of wearable devices, and more specifically, to a service-based communication connection method, a smart device, and a wearable device. Background Art

[0002] Some wearable devices include both short-range communication modules and cellular communication modules. Short-range communication can be Bluetooth, low-power Bluetooth, WiFi (Wireless Fidelity), UWB (Ultra Wide Band), etc. For example, smart watches include Bluetooth modules and cellular communication modules. Smart watches can communicate with smart devices such as mobile phones through the Bluetooth module, and smart watches can access cellular networks for communication through the cellular communication module.

[0003] Some wearable devices can communicate with smart devices such as mobile phones through short-range communication modules. Through the forwarding of the cellular module and the short-range communication module of the smart device, cellular communication can be achieved without the wearable device itself being connected to the cellular network.

[0004] However, wearable devices usually have low power consumption requirements. When the wearable device is disconnected from the short-range wireless communication, the wearable device needs to re-access the cellular network through the cellular communication module. Re-accessing the cellular network requires searching the network, measuring the cell, synchronizing and decoding, etc. before connecting to the cell, thereby accessing the cellular network. This process will generate some power consumption. More importantly, re-accessing the cellular network requires searching the network, measuring the cell, synchronizing and decoding, etc., which takes a long time. For example, some devices may take several seconds or more than ten seconds. This results in a large delay between the disconnection of the wearable device from the short-range wireless communication connection and the re-access of the wearable device to the cellular network through the cellular communication module, which will cause the communication between the wearable device and the remote device to be interrupted for a long time or the connection delay to be long, thereby affecting the user experience.

[0005] On the other hand, when the wearable device is connected to the short-range wireless communication normally, if the wearable device simultaneously performs network search, cell measurement and other operations through the cellular communication module, it will indeed reduce the delay between the disconnection of the wearable device and the short-range wireless communication connection and the re-access of the wearable device to the cellular network through the cellular communication module. However, this will generate greater power consumption and affect the battery life of the wearable device. Summary of the invention

[0006] In view of this, the present application aims to provide a communication connection method, a smart device and a wearable device to reduce the delay of the wearable device switching to cellular network communication when short-range wireless communication is unavailable, and reduce the power consumption required by the wearable device.

[0007] In a first aspect, an embodiment of the present application provides a service-based communication connection method, which is applied to a smart device, wherein the smart device and the wearable device can be connected through short-range wireless communication, and the smart device accesses a cellular network; when the wearable device and the smart device are connected through the short-range wireless communication, the smart device forwards data of the cellular network during the communication process to the wearable device through the short-range wireless communication, and the cellular network communication function of the wearable device is in a low power consumption state; the service-based communication connection method includes: obtaining a cellular communication parameter set obtained by searching the network; the cellular communication parameter set includes parameters required for accessing a cellular network; obtaining the service status of the short-range wireless communication between the wearable device; the service status indicates whether the smart device and the wearable device are transmitting service data through the short-range wireless communication; determining a target sending method for sending the cellular communication parameter set to the wearable device based on the service status; sending the cellular communication parameter set to the wearable device based on the target sending method, so that the wearable device can access the cellular network for communication based on the cellular communication parameter set when the short-range wireless communication is not available.

[0008] In the embodiment of the present application, during the short-distance wireless communication between the wearable device and the smart device, the cellular network communication function of the wearable device is in a low-power state, and the normal operation of the cellular communication function is achieved through the forwarding of the short-distance wireless communication. Since the cellular network communication function is in a low-power state, the network search, cell measurement and other operations performed by the wearable device when the short-distance wireless communication connection is normal are reduced, thereby reducing the power consumption of the wearable device. Therefore, during the period when the wearable device and the smart device are in short-distance wireless communication, the power consumption can be reduced without affecting the cellular communication of the wearable device. After the short-distance wireless communication is unavailable, the wearable device can quickly restore the cellular communication through the cellular network parameter set, reducing the interruption time (i.e., delay) of the cellular communication recovery. During the transmission of business data, the transmission of business data will generate a large power consumption. Compared with business data, the transmission of the cellular communication parameter set has a smaller impact on power consumption, and during the period of business data transmission, the communication quality between the wearable device and the smart device is usually higher. Compared with transmitting the cellular communication parameter set under the condition of low communication quality, the transmission of the cellular communication parameter set under the condition of high communication quality has a smaller impact on business data transmission, more accurate data transmission, and less power consumption increase. On the contrary, during the period when there is no business data transmission, the frequent transmission of the cellular communication parameter set may generate large power consumption. Therefore, the target transmission mode can be determined based on the business state, and the cellular communication parameter set can be sent to the smart device based on the target transmission mode, thereby reducing the power consumption of the wearable device caused by the transmission of the cellular communication parameter set without affecting the normal transmission of business data.

[0009] In one embodiment, the service status includes a service status, and the service status indicates that service data is being transmitted between the smart device and the wearable device through the short-range wireless communication; and determining a target sending method for sending the cellular communication parameter set to the wearable device based on the service status includes: if the service status is the service status, determining the target sending method as: sending the cellular communication parameter set during the sending of the service data.

[0010] In an embodiment of the present application, in a business state, business data is being transmitted between the smart device and the wearable device through short-range wireless communication. During this period, the transmission of business data will generate greater power consumption. Compared with business data, the transmission of cellular communication parameter sets has less impact on power consumption. During the period of business data transmission, the communication quality between the wearable device and the smart device is usually higher. Compared with transmitting the cellular communication parameter set under low communication quality, transmitting the cellular communication parameter set under high communication quality has less impact on business data transmission, data transmission is more accurate, and power consumption increases less.

[0011] In one embodiment, the service state includes a no-service state, wherein the no-service state indicates that service data is not transmitted between the smart device and the wearable device through the short-range wireless communication; in the no-service state, the wearable device wakes up at intervals of a first preset time duration; and determining a target sending method for sending the cellular communication parameter set to the wearable device based on the service state includes: if the service state is a no-service state, determining the target sending method as: when the communication quality with the wearable device is less than a preset threshold, sending the cellular communication parameter set to the wearable device, so that the wearable device receives the cellular communication parameter set after waking up.

[0012] In the embodiment of the present application, in the absence of business, the wearable device wakes up at intervals of a first preset time length to receive the cellular communication parameter set from the smart device, so as to reduce the frequency of receiving the cellular communication parameter set, thereby reducing the power consumption generated by data transmission. In the case of good communication quality, the wearable device does not need to access the cellular network, so the smart device does not need to send the cellular communication parameter set to the wearable device, and when the communication quality is less than the preset threshold, it indicates that there is a risk of unavailability of the short-range wireless communication between the wearable device and the smart device. Therefore, in the absence of business, the smart device sends the cellular communication parameter set to the wearable device only when the communication quality with the wearable device is less than the preset threshold. As a result, the wearable device can receive the cellular communication parameter set in time to access the cellular network, further reducing the transmission frequency of the cellular communication parameter set and reducing the power consumption generated by data transmission.

[0013] In one embodiment, the service state includes a no-service state, and the no-service state indicates that service data is not transmitted between the smart device and the wearable device through the short-range wireless communication; in the no-service state, the wearable device wakes up at intervals of a first preset duration, and the target sending method for sending the cellular communication parameter set to the wearable device based on the service state includes: if the service state is a no-service state, determining the target sending method to send the cellular communication parameter set to the wearable device at intervals of a second preset duration, so that the wearable device receives the cellular communication parameter set after waking up; the second preset duration is N times the first preset duration, and N is an integer greater than or equal to 2.

[0014] In an embodiment of the present application, by sending a cellular communication parameter set to the wearable device at intervals of a second preset time length, the frequency of sending the cellular communication parameter set to the wearable device can be reduced, and the power consumption generated by the transmission of the cellular communication parameter set can be reduced.

[0015] In one embodiment, the service state includes a no-service state, and the no-service state indicates that service data is not transmitted between the smart device and the wearable device through the short-range wireless communication; in the no-service state, the wearable device wakes up at intervals of a first preset duration; the target sending method for sending the cellular communication parameter set to the wearable device based on the service state includes: if the service state is a no-service state, and the cellular communication parameter set indicates that a resident cell of the smart device is updated, and the updated resident cell is supported by the wearable device, then the target sending method is: directly sending the cellular communication parameter set to the wearable device.

[0016] The network cell of the smart device is usually the cell with the best communication quality. In general, the wearable device and the smart device are located close to each other and in a similar communication environment. Therefore, the network cell of the smart device is most likely the most suitable cell for the wearable device. Therefore, in the embodiment of the present application, under the premise that the network cell of the smart device is updated, the smart device does not need to wait, but directly sends a cellular communication parameter set to the wearable device, so that the wearable device can immediately receive the cellular communication parameter set of the network cell after waking up. Since the wearable device is awakened at an interval of the first preset time length, the immediate sending of the cellular communication parameter set has little effect on the frequency of data transmission and the power consumption. The immediate sending of the cellular communication parameter set can enable the wearable device to access the network cell of the smart device when short-range wireless communication is not available, so as to improve the communication quality.

[0017] In one embodiment, the target sending method for sending the cellular communication parameter set to the wearable device based on the service status includes: if the service status is a no-service status, and the cellular communication parameter set represents an update of a candidate cell of the smart device, then the target sending method includes: when the communication quality with the wearable device is less than a preset threshold, sending the cellular communication parameter set to the wearable device, so that the wearable device receives the cellular communication parameter set after waking up.

[0018] Compared with the resident cell, the communication quality between the smart device and the candidate cell is poor. Therefore, the candidate cell is most likely not the best choice for the wearable device. Therefore, in the embodiment of the present application, only when the communication quality with the wearable device is less than a preset threshold, a cellular communication parameter set is sent to the wearable device to reduce the transmission frequency of the cellular communication parameter set, thereby reducing the power consumption generated by data transmission.

[0019] In a second aspect, an embodiment of the present application also provides a service-based communication connection method, which is applied to a wearable device, wherein the wearable device and the smart device can be connected via short-range wireless communication, and the smart device accesses a cellular network; when the wearable device and the smart device are connected via the short-range wireless communication, the smart device forwards data in the cellular network communication process to the wearable device via the short-range wireless communication, and the cellular network communication function of the wearable device is in a low power consumption state; the service-based communication connection method comprises: determining a target receiving mode for a cellular communication parameter set sent to the smart device based on a service status; the service status characterizes whether service data is being transmitted between the smart device and the wearable device via the short-range wireless communication; the cellular communication parameter set includes parameters required to be used when accessing a cellular network, and when the short-range wireless communication is not available, accessing the cellular network for communication based on the cellular communication parameter set.

[0020] In one embodiment, the business state includes a business state and a no-business state, the business state indicating that business data is being transmitted between the smart device and the wearable device through the short-range wireless communication; the no-business state indicating that business data is not being transmitted between the smart device and the wearable device through the short-range wireless communication; the target receiving mode for the cellular communication parameter set sent to the smart device based on the business state includes: when in the business state, the target receiving mode is to receive the cellular communication parameter set during the transmission of the business data; when in the no-business state, the target receiving mode is to wake up at every first preset time interval to receive the cellular communication parameter set after waking up.

[0021] In a third aspect, an embodiment of the present application provides a smart device, comprising: a first short-range wireless communication module, a first cellular communication module and a processing unit; the smart device is used to access a cellular network for communication through the first cellular communication module; the first short-range wireless communication module is used to connect to a wearable device through short-range wireless communication; the processing unit is used to execute the service-based communication connection method as described in any one of the first aspects based on the first short-range wireless communication module and the first cellular communication module.

[0022] In the fourth aspect, an embodiment of the present application also provides a wearable device, comprising: a second short-range wireless communication module and a second cellular communication module, the second short-range wireless communication module being connected to the second cellular communication module; the second short-range wireless communication module is used to communicate and connect with the smart device through short-range wireless communication; when the second cellular communication module is connected to the smart device through the short-range wireless communication, the second cellular communication module is in a low power consumption state; the second short-range wireless communication module is also used to receive data forwarded by the smart device during the cellular network communication process and communicate; the wearable device executes the service-based communication connection method as described in the second aspect through the second short-range wireless communication module and the second cellular communication module.

DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solution and advantages of the embodiments of the present application more clear, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application and are not used to limit the present application.

[0033] First, the embodiments of the present application provide a smart device, a wearable device, and a communication system including the smart device and the wearable device. Figure 1 , Figure 1 A connection diagram of a communication system provided in one embodiment of the present application.

[0034] like Figure 1 As shown, in an embodiment of the present application, the smart device 100 includes a first processing unit 130, a first short-range wireless communication module 110 and a first cellular communication module 120, and the wearable device 200 includes a second processing unit 230, a second short-range wireless communication module 210 and a second cellular communication module 220.

[0035] In the smart device 100, the first processing unit 130 is connected to the first short-range wireless communication module 110 and the first cellular communication module 120 respectively, and the first short-range wireless communication module 110 is connected to the first cellular communication module 120. The first processing unit 130 is used to execute the service-based communication connection method applied to the smart device 100 provided in this application. The service-based communication connection method applied to the smart device 100 will be described later and will not be expanded here. The smart device 100 may also include other functional components, which are not limited here.

[0036] In the embodiment of the present application, the smart device 100 may be a device such as a mobile phone, a tablet computer, a laptop computer, etc. that can perform cellular communication and short-range wireless communication at the same time.

[0037] In the wearable device 200, the second processing unit 230 is connected to the second short-range wireless communication module 210 and the second cellular communication module 220, respectively, and the second short-range wireless communication module 210 is connected to the second cellular communication module 220. The wearable device 200 may also include other components, which are not limited here.

[0038] In an embodiment of the present application, the second processing unit 230 of the wearable device 200 is used to execute the service-based communication connection method provided in the present application and applied to one end of the wearable device 200. The service-based communication connection method will be described later and will not be expanded here.

[0039] In an embodiment of the present application, the wearable device 200 may be a smart watch, a smart bracelet, a sports watch, a smart glasses, or the like that is capable of performing both cellular communication and short-range wireless communication.

[0040] In the embodiment of the present application, the first short-range wireless communication module 110 and the second short-range wireless communication module 210 are short-range communication modules with different structures or different models to realize the same short-range wireless communication mode, and the first and second are the distinctions of the short-range communication modules applied on different devices. For example, in the embodiment of the present application, the short-range communication modules used by the first short-range wireless communication module 110 and the second short-range wireless communication module 210 can be Bluetooth communication modules, low-power Bluetooth modules, ultra-wideband modules, WIFI modules, etc., which are not limited here.

[0041] In some embodiments, the first short-range wireless communication and the second short-range wireless communication module 210 can simultaneously implement multiple short-range wireless communication functions. If the first short-range wireless communication and the second short-range wireless communication module 210 can both implement Bluetooth and low-power Bluetooth functions, then in the first short-range wireless communication and the second short-range wireless communication module 210, the same set of antennas and radio frequency units can be time-shared between Bluetooth and low-power Bluetooth.

[0042] Similarly, the first cellular communication module 120 and the second cellular communication module 220 are cellular communication modules that implement the same or different cellular communication modes, and the first and second cellular communication modules are distinguished by being applied on different devices. For example, in an embodiment of the present application, the first cellular communication module 120 and the second cellular communication module 220 can be one of a 6G (6th generation mobile networks, sixth generation mobile communication technology) communication module, a 5G (5th Generation Mobile Communication Technology, fifth generation mobile communication technology) communication module, a 4G (the 4th generation mobile communication technology, fourth generation mobile communication technology) communication module, a 3G (3rd-Generation, third generation mobile communication technology) communication module or a 2G (2-Generation wireless telephone technology, second generation mobile communication technology specification) communication module, and are not limited here.

[0043] In some embodiments of the present application, the wearable device 200 and the smart device 100 have the same eSIM (Embedded-SIM, electronic SIM card) or SIM card number. When the wearable device 200 answers or makes a call and when the short-range wireless communication connection between the wearable device 200 and the smart device 100 is not available, the wearable device 200 can use the second cellular communication module 220 to answer or make a call. When the short-range wireless communication connection between the wearable device 200 and the mobile phone is available, the call is answered or made through the smart device 100.

[0044] In the embodiment of the present application, compared with the smart device 100, the wearable device 200 has higher requirements on power consumption (especially standby power consumption) than the smart device 100, and the wearable device 200 has higher requirements on battery life than the smart device 100. For example, the wearable device 200 is a smart watch, and the smart device 100 is a mobile phone. Compared with the mobile phone, the smart watch has higher requirements on power consumption.

[0045] Next, the communication method of the communication system provided by this application will be described. Figure 1 As shown, in the embodiment of the present application, the smart device 100 and the wearable device 200 can be connected via short-range wireless communication, that is, the first short-range wireless communication module 110 and the second short-range wireless communication module 210 are in communication connection.

[0046] When the wearable device 200 is connected to the smart device 100 via the short-range wireless communication, the cellular network communication function of the wearable device 200 is in a low-power state. In the low-power state, the second short cellular communication module turns off some functions to reduce power consumption. For example, the low-power state includes but is not limited to the second short cellular communication module being in a turned-off state (i.e., not working), or the state of turning off the network search function or the state of measuring the cell function. In the low-power state, the second short cellular communication module can effectively reduce the network search, cell measurement and other operations performed by the wearable device when the short-range wireless communication connection is normal, thereby reducing the power consumption of the wearable device.

[0047] At the same time, when the wearable device 200 is connected to the smart device 100 via short-range wireless communication, the smart device 100 forwards data in the cellular network communication process to the wearable device 200 via short-range wireless communication.

[0048] Since the cellular network communication function of the wearable device 200 is in a low power consumption state, it may not be able to meet the normal cellular communication needs of the wearable device 200, such as making calls, answering calls, accessing the Internet, etc. Therefore, in an embodiment of the present application, if the wearable device 200 needs to perform cellular network communication normally, it can be forwarded by the smart device 100.

[0049] In this embodiment, the smart device 100 normally accesses the communication base station through the first cellular communication module 120, thereby accessing the cellular network. When the wearable device 200 needs to send data, it can first send the data to the smart device 100 through short-range wireless communication, and the smart device 100 then forwards the information to the base station and / or remote device through the cellular network. And, when the wearable device 200 needs to receive data, the smart device 100 first receives the signal from the base station and / or remote device through cellular communication, and then the smart device 100 forwards the wearable device 200 through short-range wireless communication.

[0050] Therefore, when the wearable device 200 is connected to the smart device 100 through short-range wireless communication, the cellular network communication function is put into a low-power state to reduce power consumption, and then the data in the cellular network communication process is forwarded through the smart device 100 to normally realize the cellular network communication function.

[0051] At the same time, when the wearable device 200 does not receive the business data transmitted by the smart device 100 through short-range wireless communication, the wearable device 200 is also in a low-power state, and wakes up at every first preset time interval. After waking up, the wearable device 200 can receive the data transmitted by the smart device 100 when the wearable device 200 is in a low-power state.

[0052] Accordingly, in an embodiment of the present application, when the wearable device 200 is unavailable for short-range wireless communication, the second cellular communication module 220 of the wearable device 200 returns to normal, so that the cellular network communication function can operate normally. Among them, the unavailability of short-range wireless communication includes but is not limited to the disconnection of short-range wireless communication, or whether the communication quality of short-range wireless communication is within the range of normal communication. If the communication quality exceeds the range, it is difficult to support better communication, which will also make the communication unavailable. For example, RSSI (Received Signal Strength Indication) is less than a preset value, SNR (Signal-to-Noise Ratio) is less than a preset value, and for example, the bit error rate or frame error rate or packet loss rate is greater than a preset value.

[0053] Next, the present application provides a service-based communication connection method, which can be applied to the aforementioned smart device 100.

[0054] See also Figure 2 , Figure 2 A flow chart of a service-based communication connection method applied to a smart device 100 provided in an embodiment of the present application. The service-based communication connection method applied to the smart device 100 includes:

[0055] S110, acquiring a cellular communication parameter set obtained by searching the network.

[0056] The cellular communication parameter set includes parameters required for accessing a cellular network, including but not limited to cell information, PRACH (random access channel) configuration information, frequency information, time slot information, network identification (such as a public land mobile network identity), priority information, etc. The cellular communication module can send an access request to the base station based on the information in the cellular communication parameter set. After receiving the access request, the base station sends an access confirmation message to the cellular communication module of the device, thereby completing the network stationing of the device.

[0057] In an embodiment of the present application, the cellular communication parameter set includes the current resident cell and candidate cells of the smart device 100. The current resident cell refers to the cell of the cellular network currently accessed by the smart device 100, and the candidate cell refers to other cells of the cellular network that the smart device 100 can access.

[0058] Among them, the candidate cell is obtained by the smart device 100 actively searching the network and receiving the information broadcast by the base station of the cellular network. The base station broadcasts the neighboring cell information through the system information block, and the smart device 100 can obtain the information of the candidate cell by receiving the broadcast information. Among them, the system information block includes different types of system information blocks for networks of different generations, which are neighboring cell information, frequency information, priority information, etc. For example, for the 2G network in the cellular network, it includes the system information in the broadcast control channel, etc., the 3G network includes the information of system information block 3 and system information block 5, etc., the 4G network includes the information of system information block 3, system information block 4 and system information block 5, etc., and the 5G network includes the information of system information block 1, system information block 3 and system information block 5, etc. Each system information block (including system information block 1, system information block 3, system information block 4, system information block 5) includes the frequency point, priority, reselection parameters and other information of the neighboring cell, and the smart device 100 can determine the candidate cell through the information obtained.

[0059] In an embodiment of the present application, the smart device 100 actively searches for a network by regularly measuring the current cell and neighboring cells broadcast by the base station, including but not limited to measuring signal strength and signal quality, so as to determine a new cell and update candidate cells based on the measurement results, and perform cell reselection, etc.

[0060] For the above, reference may be made to the relevant contents of cellular communications, which will not be further elaborated here.

[0061] In an embodiment of the present application, the acquired cellular communication parameter set includes parameters required to be used when accessing a cellular network, including but not limited to a first parameter set of a cell in which the smart device 100 is currently stationed and a second parameter set of a candidate cell, and there may be multiple candidate cells, and the cellular communication parameter set may include second sub-parameter sets corresponding to different candidate cells.

[0062] In one embodiment of the present application, the acquired cellular communication parameter set may include a portion of cellular communication parameter sets corresponding to updated resident cells and candidate cells among all resident cells and candidate cells detected by the smart device 100, compared with the cellular communication parameter set sent to the wearable device last time. That is, the acquired cellular communication parameter set is updated data, and it is not necessary to acquire all data.

[0063] In this embodiment, the update of the cellular communication parameter set includes but is not limited to the addition and reduction of resident cells and candidate cells, and changes in the communication quality with candidate cells and resident cells, such as changes in signal strength, signal quality, priority information, etc.

[0064] In some embodiments, the updated candidate cells may be further selected to select a cellular communication parameter set including a portion of the updated candidate cells and send it to the wearable device 200, thereby reducing the amount of data transmission.

[0065] In some embodiments, the cellular communication parameter set may be selected based on the communication quality of each cell, such as by arranging them according to the communication quality, selecting the first k cells where updates occur and including the parameter set in the cellular communication parameter set, and then transmitting them to the wearable device 200 .

[0066] S120, obtaining a service status of short-range wireless communication with the wearable device.

[0067] In the embodiment of the present application, the service status indicates whether service data is being transmitted between the smart device 100 and the wearable device 200 via short-range wireless communication. The service data includes but is not limited to data forwarded by the smart device 100 when the wearable device 200 communicates using a cellular network.

[0068] In the embodiment of the present application, the service state includes a service state (or "active state") and a non-service state (or "standby state"). The service state indicates that service data is being transmitted between the smart device 100 and the wearable device 200 via short-range wireless communication. For example, the smart device 100 is a mobile phone, the wearable device 200 is a headset, and the wearable device 200 listens to music from the mobile phone via short-range wireless communication, and makes calls or audio and video exchanges via the mobile phone. The non-service state indicates that service data is not currently being transmitted between the smart device 100 and the wearable device 200 via short-range wireless communication.

[0069] The service status may be determined by detecting whether the first short-range wireless communication module 110 is transmitting data.

[0070] S130, determining a target sending method for sending a cellular communication parameter set to the wearable device based on the service status.

[0071] The business state can characterize the power consumption of the wearable device 200 to a certain extent. For example, in a business state, business data needs to be transmitted between the smart device 100 and the wearable device 200, and the power consumption during this period is relatively large. In a non-business state, the wearable device 200 and the smart device 100 do not need to transmit business data. At this time, the wearable device 200 should reduce power consumption as much as possible, so the wearable device 200 will reduce the frequency of receiving data, and wake up and receive data every first preset time interval. Therefore, in an embodiment of the present application, the target sending mode of the corresponding cellular communication parameter set can be configured for different business states, so that the transmission of the cellular communication parameter set can meet the current power consumption requirements of the wearable device 200.

[0072] In the embodiment of the present application, the wearable device wakes up at the first preset time interval mainly refers to the short-range wireless communication function of the wearable device being awakened (or the second short-range wireless communication module being awakened). The first preset time can be 500ms, 1s, 2s, 4s, etc., which is not limited here.

[0073] In one embodiment, if the service state is a service state, the target sending mode may be determined as: sending the cellular communication parameter set during the sending of service data.

[0074] As mentioned above, during the business state, the transmission of business data will generate greater power consumption. Therefore, compared with the transmission of business data, the transmission power consumption requirement of the cellular communication parameter set is lower, and the power consumption impact of sending the cellular communication parameter set during the transmission of business data is relatively small.

[0075] In some embodiments of the present application, if it is necessary to send a cellular communication parameter set during the transmission of service data, the current communication quality can also be determined. If the communication quality is greater than a preset threshold, it is determined that the cellular communication parameter set can be sent during the transmission of service data. Conversely, if the communication quality during the transmission of service data is less than the preset threshold, it is prohibited to send the cellular communication parameter set during the transmission of service data. In this way, the impact of sending the cellular communication parameter set on the transmission of the original service data is reduced.

[0076] In one embodiment, if the service state is a no service state, the target sending method is determined as follows: when the communication quality with the wearable device 200 is less than a preset threshold, a cellular communication parameter set is sent to the wearable device 200, so that the wearable device 200 receives the cellular communication parameter set after waking up.

[0077] As mentioned above, in a non-business state, since there is no business data to be transmitted, the wearable device 200 has no need for data transmission. Under normal circumstances, the cellular communication of the wearable device 200 is most likely in an unused state. Therefore, even if the wearable device 200 wakes up to receive data once every first preset time interval, it will not affect the user's usage experience too much.

[0078] In the embodiment of the present application, if the communication quality between the smart device 100 and the wearable device 200 is greater than a preset threshold, it indicates that the short-range wireless communication connection between the smart device 100 and the wearable device 200 is good. At this time, the wearable device 200 can forward the second cellular communication module 220 in a low-power state through the smart device 100 and the second short-range wireless communication module 210 to realize the cellular communication function. During this period, there is no need to send a cellular communication parameter set to the wearable device 200 to reduce the frequency of sending the cellular communication parameter set, thereby reducing power consumption.

[0079] On the contrary, if the communication quality between the smart device 100 and the wearable device 200 is less than the preset threshold, it indicates that there is a risk of disconnection of the short-range wireless communication between the smart device 100 and the wearable device 200, and the short-range wireless communication between the smart device 100 and the wearable device 200 is unavailable. In this case, the cellular communication parameter set is sent to the wearable device 200 in a timely manner, so that the wearable device 200 can receive the short-range wireless communication after waking up, and can access the cellular network based on the received short-range wireless communication when the short-range wireless communication is unavailable.

[0080] Therefore, in an embodiment of the present application, when the communication quality between the smart device 100 and the wearable device 200 is less than a preset threshold, a cellular communication parameter set is sent to the wearable device 200. This can reduce the transmission frequency of the cellular communication parameter set without affecting the normal cellular communication of the wearable device 200, thereby reducing the power consumption of the wearable device 200.

[0081] In the embodiments of the present application, the communication quality between the smart device 100 and the wearable device 200 can be measured using parameter indices such as RSSI (Received Signal Strength Indicator), BER (Bit Error Rate), PER (Packet Error Rate), SNR (Signal-to-Noise Ratio), and the number of retransmissions, without limitation.

[0082] In other embodiments of the present application, if the business state is a no-business state, the target sending method can also be determined as: sending a cellular communication parameter set to the wearable device 200 at every second preset time interval, so that the wearable device 200 receives the cellular communication parameter set after waking up.

[0083] In this embodiment, the second preset duration is N times the first preset duration, where N is an integer greater than or equal to 2. That is, the second preset duration is greater than the first preset duration, and this method can also reduce the frequency of the smart device 100 sending the cellular communication parameter set to the wearable device 200, thereby reducing the power consumption caused by the wearable device 200 receiving the cellular communication parameter set in a non-service state.

[0084] In some embodiments, if the service state is a no-service state, and the cellular communication parameter set represents an update of a resident cell of the smart device 100 , and the updated resident cell is supported by the wearable device 200 , the target sending method is: directly sending the cellular communication parameter set to the wearable device 200 .

[0085] The resident cell is usually the cell with the best communication quality with the setting, which is easier to search and has better transmission effect. In most cases, the wearable device 200 and the smart device 100 are located close to each other, and the resident cell of the smart device 100 is likely to be the cell that the wearable device 200 is most suitable for. Therefore, when the smart device 100 switches the resident cell to the new resident cell, and the new resident cell is supported by the wearable device 200, the smart device 100 can directly send the communication parameter set of the new resident cell to the wearable device 200, so that the wearable device 200 can connect to the resident cell of the smart device 100 when short-range wireless communication is not available, thereby improving the network search speed of the wearable device 200 and reducing the time and power consumption required to switch to the cellular network for communication.

[0086] Among them, the smart device 100 directly sends the cellular communication parameter set to the wearable device 200, and the wearable device 200 still needs to receive the cellular communication parameter set after waking up.

[0087] As for the candidate cells, in some embodiments of the present application, if the service state is a no-service state, and the cellular communication parameter set represents an update of the candidate cells of the smart device 100, the target sending method may also include: when the communication quality with the wearable device 200 is less than a preset threshold, sending the cellular communication parameter set to the wearable device 200, so that the wearable device 200 receives the cellular communication parameter set after waking up.

[0088] Compared with the resident cell, the communication quality of the candidate cell is slightly worse, and its efficiency in being searched by the network is also slightly lower. Therefore, in the embodiment of the present application, if there is an update to the candidate cell, it does not need to be transmitted to the wearable device 200 immediately, thereby reducing the transmission frequency of the cellular communication parameter set and thus reducing power consumption. When the communication quality between the smart device 100 and the wearable device 200 is less than the preset threshold, the cellular communication parameter set is sent to the wearable device 200. Therefore, even if the wearable device 200 cannot connect to the resident cell of the smart device 100, it can receive the cellular communication parameter set of the candidate cell under the premise that there is a risk of unavailability of short-range wireless communication, so that the wearable device 200 can reduce the time and power consumption required to connect to the candidate cell.

[0089] In addition, in the above embodiment, the wearable device 200 is awakened by actively waking up at intervals of a first preset time duration when there is no business, or by being awakened by the smart device 100 (such as when business data needs to be transmitted between the smart device 100). Regardless of the circumstances in which the wearable device 200 is awakened, the wearable device 200 can receive the cellular communication parameter set, and does not necessarily need to receive the cellular communication parameter set at intervals of the first preset time duration.

[0090] S140: Send a cellular communication parameter set to the wearable device based on the target sending mode.

[0091] In an embodiment of the present application, a cellular communication parameter set can be sent to the wearable device 200 through the target sending method determined in the aforementioned S130, so that the wearable device 200 receives the cellular communication parameter set during the service data transmission process or after waking up, and then when short-range wireless communication is not available, the wearable device 200 can access the cellular network for communication based on the cellular communication parameter set.

[0092] In addition, in the process of the device accessing the cellular network, the device needs to perform relatively complex steps such as network search, cell measurement, frequency band scanning, signal detection, synchronization and decoding of base station broadcast channels (not listed in full, refer to the prior art) to obtain the cellular communication parameter set, and then access the cellular network through the cellular communication parameter set. In the embodiment of the present application, when the wearable device 200 is not available for short-range wireless communication, the wearable device 200 can determine the cell to be connected through the cellular network communication parameter set and send an access request. As a result, the wearable device 200 will reduce some steps required for accessing the cellular network, such as reducing the network search, cell measurement, frequency band scanning, signal detection, synchronization and decoding of base station broadcast channels, and effectively reduce the power consumption of the wearable device 200 when reconnecting to the cellular network. By reducing the time required for the process of connecting to the cellular network, the delay waiting time caused by network switching can be reduced, and the user experience can be improved. In addition, since some operations such as network search and cell measurement performed when switching networks are reduced, the power consumption of the wearable device can also be reduced to a certain extent.

[0093] Based on the same inventive concept, the embodiment of the present application also provides a communication connection method applied to a wearable device 200. Among them, the wearable device 200 can communicate and connect with the smart device 100 through short-range wireless communication, and when the wearable device 200 and the smart device 100 are connected through short-range wireless communication, the wearable device 200 puts its own cellular network communication function in a low-power state, and receives the data of the wearable device 200 in the cellular network communication process forwarded by the smart device 100 through short-range wireless communication. The connection relationship between the wearable device 200 and the smart device 100 can refer to the above content, which will not be repeated here.

[0094] See also Figure 3 , the service-based communication connection method applied to the wearable device 200 includes:

[0095] S210, determining a target receiving method for a cellular communication parameter set sent from a smart device based on a service state and receiving the cellular communication parameter set.

[0096] In one embodiment, in the service state, the target receiving mode is to receive the cellular communication parameter set during the service data transmission. In the non-service state, the target receiving mode is to wake up at a first preset time interval to receive the cellular communication parameter set after waking up.

[0097] S220: When short-range wireless communication is unavailable, access a cellular network for communication based on a cellular communication parameter set.

[0098] As mentioned above, the cellular communication parameter set includes parameters required for accessing a cellular network. In the embodiment of the present application, when short-range wireless communication is unavailable, the wearable device 200 cannot communicate with the cellular network through short-range wireless communication and forwarding of the smart device 100, and therefore needs to re-access the cellular network. While the wearable device 200 is communicating with the wearable device 200 through short-range wireless communication, the wearable device 200 has received a cellular communication parameter set including parameters required for accessing a cellular network. When short-range wireless communication is unavailable, the cellular communication parameter set can reduce steps such as network search, frequency band scanning, signal detection, synchronization, and decoding of base station broadcast channels, reduce the time required to re-access the cellular network, and reduce the power consumption generated during this period.

[0099] In some embodiments of the present application, the cellular network communication parameter set includes multiple candidate cells obtained by the smart device 100 searching the network and the corresponding second sub-parameter set. In this case, S220 may include: when short-range wireless communication is not available, selecting a second target candidate cell from multiple candidate cells in the cellular network communication parameter set based on the communication quality of each candidate cell; when short-range wireless communication is not available, accessing the cellular network for communication based on the second sub-parameter set of the second target candidate cell.

[0100] In this embodiment, the wearable device 200 can detect the communication quality of each candidate cell, and select one of the candidate cells with the best communication quality or the quality that meets the requirements for access. The wearable device 200 sends an access request to the corresponding candidate cell or base station through a random access channel. After receiving the access request, the base station sends an access confirmation message to the wearable device 200, and the wearable device 200 thus completes the initial network access.

[0101] In some embodiments of the present application, if the cellular network communication parameter set includes a first parameter set of a resident cell of the smart device 100 and a second parameter set of a candidate cell, the first parameter set is preferentially used to access the cellular network.

[0102] In some embodiments of the present application, if the cellular network communication parameter set includes a first parameter set of the resident cell of the smart device 100 and a second parameter set of the candidate cells, the communication quality between the resident cell and each candidate cell can also be judged, and the parameter set corresponding to the optimal or required cell can be selected according to the communication quality to access the cellular network.

[0115] S350: When short-range wireless communication is unavailable, the wearable device 200 accesses the cellular network for communication based on the cellular network communication parameter set.
