Method of portable device communication, communication system and corresponding device

FIELD OF THE INVENTION

The present invention relates to the field of communication technology and, in particular, to a communication method of a wearable device, a communication system and a corresponding device.

State of the art

Currently, a wearable device, such as a smartwatch or bracelet, typically communicates with a terminal device, such as a mobile phone, via Bluetooth to realize features such as event notifications or information synchronization. For example, when there is an incoming call to a mobile phone, the smart watch can be notified via Bluetooth, and then the smart watch notifies you of an incoming call. The wearable device is user-friendly and therefore attracts the attention of an increasing number of equipment manufacturers.

At home, the wearable device and the terminal device can be located in different places. For example, a mobile phone is in the bedroom, and a user who wears a bracelet is in the living room; in this case, the mobile phone is far from the bracelet; since the coverage area of ​​the Bluetooth connection is relatively small, the mobile phone cannot communicate with the bracelet using Bluetooth, so the communication between the mobile phone and the wearable device cannot be supported.

Below with reference to the attached drawings, a clear and complete description of the technical solutions of the embodiments of the present invention. It is clear that the described embodiments of the invention are some, and not all, embodiments of the present invention. All other embodiments of the invention obtained by a person skilled in the art without creative efforts based on the described embodiments of the present invention should fall within the protection scope of the present invention.

In the description, claims and accompanying drawings of the present invention, the terms “first”, “second”, “third”, “fourth” and so on (if they exist) are intended to distinguish between similar objects, but they do not necessarily indicate a specific order or sequence . It should be understood that the data defined in this way are interchangeable under appropriate circumstances, so that the embodiments of the present invention described herein can be implemented in accordance with orders different from the order shown and described herein. In addition, the terms “comprises,” “includes,” or any other variations are intended to mean a non-limiting “include” property, for example, a process, method, system, product, or device,

In one embodiment of the present invention, there is provided a method for communicating a wearable device, which can mainly be used in the data exchange systems shown in FIG. 1a and FIG. 1b. The communication system shown in FIG. 1a, comprises a user device, a wearable device, and a network connection device. A user device may be a device that can access a network using a network connection device and which is a device such as a mobile phone, tablet, or personal computer. The wearable device can be a device that can be used to pair with a user device (for example, can be the smart bracelet of FIG. 1), and which can be a smart bracelet or smart watch. The network connection device may be a device which has the function of connecting to a network, that is, it can be a device such as a home Wi-Fi (“Wireless Quality”) router and gateway. In one embodiment of the present invention, the network connection device may require a Bluetooth function.

In general, a communication connection between a user device and a wearable device can be established directly, for example, it can be a Bluetooth connection. A user device may send a message to a wearable device for execution. For example, when there is an incoming call to the user device, it sends a message to the wearable device, and the wearable device shows an incoming call to the user device.

However, in this embodiment, when the communication connection between the user device and the wearable device is disconnected for reasons such as distance, an indirect communication connection can be established between the user device and the wearable device using the network connection device. More specifically, a communication connection is established, that is, a connection corresponding to a certain protocol, and which is a connection between a network connection device and a user device, for example, a communication connection corresponding to a universal plug and play protocol (UPnP) or a communication connection corresponding to a protocol Wi-fi Bluetooth communication established between the network connection device and the wearable device. A message sent by the user device to the wearable device may not be directly sent to the wearable device using the network connection device.

The communication system shown in FIG. 1b, comprises a user device, a network connection device, a wearable device, and at least one bridge device. The connection between the user device and the network connection device is called the connection between the user device and the network connection device of FIG. 1a. Each bridge device can be connected to a network connection device using a power cable, a communication connection, that is, a Bluetooth connection, can be established between the network connection device and the wearable device using any bridge device, so that the network connection device can conclude information sent by the user device to the Bluetooth package,

The main functions of the bridge device are to provide a coverage area between the network connection device and the wearable device and to ensure that a message sent by the network connection device can be delivered to the wearable device.

The communication method of the wearable device in this embodiment of the present invention is carried out using the network connection device in the system shown in FIG. 1a or FIG. 1b. In FIG. 2 shows a block diagram containing the following.

Step 101. It is determined that the second Bluetooth connection between the user device and the wearable device is disconnected, and the first Bluetooth connection is established between the network connection device in the network to which the user device belongs and the wearable device.

In general, a second Bluetooth connection is established between the user device and the wearable device, and the user device can directly communicate with the wearable device. If the second Bluetooth connection is disconnected, in this embodiment, in order for the user device to not directly communicate with the wearable device using the network connection device, the network connection device separately establishes a communication connection with the wearable device and a communication connection with the user device. For a communication connection between a network connection device and a user device, if the user device accesses the network using the network connection device, This establishes a communication connection between the network connection device and the user device. For a communication communication connection between a network connection device and a wearable device, a first Bluetooth connection between a network connection device and a wearable device can be started in the following cases.

(1) When the user device detects that the second Bluetooth connection with the wearable device is disconnected, or when the user device detects that a third communication connection has been made with the network connection device, the user device can directly send a trigger command to the user’s network connection device, while the trigger used to indicate the establishment of a first Bluetooth connection between the network connection device and the wearable device. Upon receipt of a triggering command directed by the user device, the network connection device may determine that the second Bluetooth connection between the user device and the wearable device is disconnected, and may actively establish the first Bluetooth connection with the wearable device. More specific, after receiving the trigger command, the network connection device sends a paging Bluetooth message. When a disconnection of the second Bluetooth connection with the user device is detected, the wearable device determines whether a Bluetooth paging message sent by the network connection device can be received. Alternatively, if the second Bluetooth connection between the wearable device and the user device is not disconnected, the wearable device still determines in real time whether a Bluetooth paging message sent by the network connection device is received; if a Bluetooth paging message is received, a Bluetooth paging response is sent to the network connection device; if the network connection device receives a Bluetooth paging response sent by the wearable device,

(2) After finding the Bluetooth signal of the wearable device, the network connection device determines that the second Bluetooth connection between the user device and the wearable device is disconnected. More specifically, the network connection device may periodically send a paging Bluetooth message. When a disconnection of the second Bluetooth connection with the user device is detected, the wearable device determines whether a Bluetooth paging message sent by the network connection device can be received. Alternatively, if the second Bluetooth connection between the wearable device and the user device is not disconnected, the wearable device still determines in real time whether a Bluetooth paging message is received; if the bluetooth paging message is received, send a Bluetooth paging response to the network connection device; if the network connection device receives a Bluetooth paging response sent by the wearable device, then a first Bluetooth connection with the wearable device is established.

(3) After the Bluetooth signal of the wearable device is found, the network connection device sends a confirmation message to the user device, and the confirmation message is used to request the user device to determine whether to establish the first Bluetooth connection between the network connection device and the wearable device. If a confirmation message returned by the user device is received, the network connection device determines that the second Bluetooth connection between the user device and the wearable device is disconnected, and then establishes the first Bluetooth connection with the wearable device; if a non-acknowledgment message returned by the user device is received, then the first Bluetooth connection may not be established.

It should be noted that in the second case, after the network connection device finds the Bluetooth signal of the wearable device and determines the second Bluetooth connection, the first Bluetooth connection is established; or after the network connection device finds the Bluetooth signal of the wearable device, first the first Bluetooth connection is established and then the user device disconnects the second Bluetooth connection to determine that the second Bluetooth connection is disconnected.

It should be noted that in these two cases of communication systems, which are shown in FIG. 1a and FIG. 1b, the established first Bluetooth connections between the network connection device and the wearable device are different. In the system shown in FIG. 1a, a direct first Bluetooth connection is established between the network connection device and the wearable device; however, in the system shown in FIG. 1b, an indirect first Bluetooth connection is established between the network connection device and the wearable device using a bridge device that communicates with the network connection device.

It should also be noted that, if desired, after establishing the first Bluetooth connection between the network connection device and the wearable device, the network connection device can further send a notification message to the user device, while the notification message is used to notify the user device that the first connection is established Bluetooth between the network connection device and the wearable device, so that the user device can send the first information to the wearable device using a network connection device.

Step 102. The network connection device receives the first information sent by the user device via the third communication connection to the network connection device, wherein the user device sends the first information to the network connection device through the third communication connection when the second Bluetooth connection between the user device and the wearable device is disconnected .

Step 103. The network connection device sends the first information to the wearable device through the first Bluetooth connection established in step 101.

After establishing the first Bluetooth connection between the network connection device and the wearable device, the user device may first send the first information to the network connection device to be sent to the wearable device, and then the network connection device sends the first information to the wearable device. The first information may be content, command, data, and the like that the user device directs to the wearable device. The format of the first information sent by the user device to the network connection device may be the same or different from the format of the first information sent by the network device to the wearable device. When the user device sends the first information to the network connection device, a communication protocol format supported by a third communication connection may be used; and when the network connection device sends the first information to the wearable device, they mainly use the Bluetooth protocol format. Therefore, in a specific operation, the network connection device can convert the first information in the format of the communication protocol supported by the third communication connection into the first information in the format of the Bluetooth protocol.

More specifically, the third communication connection between the network connection device and the user device may be a communication connection that supports the Internet Protocol (IP), so that the network connection device can receive the first information sent by the user device using the Internet protocol. More specifically, the network connection device may receive first information, which is presented in the format of the Bluetooth protocol and which is carried in the payload of the IP packet, and can send the first information to the wearable device through the first Bluetooth connection; or the network connection device can receive the first information, which is presented in the protocol format of a higher layer and which is carried in an IP packet, and send the first information to the wearable device through the first Bluetooth connection. Higher layer protocols include, but are not limited to: UPnP protocol; Alliance Protocol (DLNA) for digital home networks; the Intelligent Grouping Protocol (IGRS) and resource sharing, also called the IGRS protocol; Hypertext Transfer Protocol (HTTP) Transmission Control Protocol (TCP); and a datagram protocol (UDP). The network connection device converts the first information in a higher layer protocol format into the first information in a Bluetooth protocol format. which is also called the IGRS protocol; Hypertext Transfer Protocol (HTTP) Transmission Control Protocol (TCP); and a datagram protocol (UDP). The network connection device converts the first information in a higher layer protocol format into the first information in a Bluetooth protocol format. which is also called the IGRS protocol; Hypertext Transfer Protocol (HTTP) Transmission Control Protocol (TCP); and a datagram protocol (UDP). The network connection device converts the first information in a higher layer protocol format into the first information in a Bluetooth protocol format.

The third communication connection may further be a communication connection that supports the universal plug and play protocol. The network connection device may receive the first information, which is presented in the UPnP protocol format and which the user device sends, or can convert the first information in the UPnP protocol format to the first information in the Bluetooth protocol format, and then forward the first information to the wearable device via the first Bluetooth connection.

The third communication connection may further be a connection that supports the Wi-Fi protocol. The network connection device can receive the first information, which is presented in the format of the Bluetooth protocol and which is transferred in the payload of the control frame (MAC) of access to the Wi-Fi protocol data medium, and can send the first information to the wearable device via the first Bluetooth connection; or a network connection device may receive first information that is presented in a higher layer protocol format and which the user device sends using Wi-Fi, and can convert the first information in a higher layer protocol format into the first information in a Bluetooth protocol format and can send the first information to a wearable device via a first Bluetooth connection. Higher layer protocols include, but are not limited to, UPnP, DLNA, IGRS, HTTP, TCP, UDP, and IP.

It should be noted that when the network connection device sends the first information through the first Bluetooth connection to the system shown in FIG. 1a, a network connection device can directly forward the first information to a wearable device; for the system shown in FIG. 1b, a Bluetooth-compliant communication connection can be established between the network connection device and the wearable device using any bridge device, so that the network connection device can wrap information sent by the user device in the Bluetooth packet and transmit the Bluetooth packet to the bridge device using the power cable protocol and then the bridge device sends a Bluetooth packet to the wearable device in the communication range of the bridge device.

Further, for the second information actively sent by the wearable device to the user device, the network connection device receives the second information that the wearable device sends through the first Bluetooth connection, the second information may be a notification or data that the wearable device sends to the user device, information which the wearable device reports to the user device, or the like. The network connection device may forward the second information to the user device through a third communication connection with the user device. The format of the second information sent by the wearable device to the network connection device may be the same or different from the format of the second information,

You can find out that in the method of this embodiment, if the second Bluetooth connection between the user device and the wearable device is disconnected, a first Bluetooth connection is established between the network connection device and the wearable device, and the network connection device can send the first information to the wearable device via the first Bluetooth connection directed by the user device. Thus, indirect communication between the user device and the wearable device is realized using a network connection device, so that the user device and the wearable device are not limited by the communication range.

It should be noted that in the communication method in steps 101-103, the user device does not directly communicate with the wearable device using the network connection device in the network to which the user device belongs. In one case, more specifically, under any of the conditions below, the first Bluetooth connection between the network connection device and the wearable device is disconnected and the user device can directly communicate with the wearable device.

The network connection device receives a first notification message sent by the user device, wherein the first notification message is used to cause the network connection device to disconnect the first Bluetooth connection between the network connection device and the wearable device; and a third communication connection between the network connection device and the user device is disconnected.

It should be further noted that the communication method in steps 101-103 indicates the communication that takes place after configuring each device in the system shown in FIG. 1a or FIG. 1b. Therefore, prior to step 101, the user device further configures the network connection device. More specifically, prior to step 101, the network connection device may further perform the configuration step by any of the methods described below. In FIG. 3 shows a block diagram containing the following.

(1) The user device directly configures.

Step 104. The network connection device receives the first configuration information sent by the user device, the first configuration information comprising a Bluetooth address of the wearable device and a key for communication between the network connection device and the wearable device; and may further comprise information such as a pairing relationship between the user device and the wearable device. The network connection device stores the first configuration information, while the network connection device uses the first configuration information to direct the first information to the wearable device via the first Bluetooth connection. If desired, if the first configuration information does not contain a pairing relationship between the user device and the wearable device, the network connection device may generate a pairing relationship between the user device and the wearable device in accordance with the first configuration information. Thus, when information is transferred between the network connection device and the wearable device, the network connection device can establish the first Bluetooth connection in accordance with the first configuration information and transmit the information via the first Bluetooth connection.

Further, the network connection device may further receive the second configuration information sent by the user device, and the second configuration information contains Bluetooth service information that the wearable device supports, such as information about the characteristics of the Bluetooth protocol or the command of the Bluetooth protocol. Therefore, the network connection device may establish a mapping relationship between the Bluetooth service information and the service information that is supported by the third communication connection, and may maintain the mapping relationship. When directing the first information to the wearable device, the network connection device can convert, in accordance with the matching relation, the first information sent through the third communication connection to the first information,

When establishing a matching relationship, the network connection device basically establishes a correspondence between each piece of information from the information of the Bluetooth service and each piece of information from the service information supported by the third communication connection, for example, establishes a correspondence between a command or message conforming to the Bluetooth protocol and the command or a message conforming to the protocol supported by the third communication connection.

(2) The user device does not directly configure so that the network connection device actively implements Bluetooth pairing with the wearable device.

Step 105. The network connection device receives a procedure request message sent by the user device, wherein the procedure request message is used to request the network connection device to perform the Bluetooth pairing procedure with the wearable device; and the network connection device performs the Bluetooth pairing procedure with the wearable device in accordance with the procedure request message. That is, the network connection device actively sends a Bluetooth pairing request to the wearable device. If pairing is successful, the network connection device can save information about the wearable device, including information such as a Bluetooth address and key. Further, the network connection device generates a pairing relationship between the user device and the wearable device.

(3) The user device does not directly configure so that the network connection device passively agrees to pair with the wearable device.

Step 106. The network connection device receives a mode request message sent by the user device, wherein the mode request message is used to request the network connection device to turn on the Bluetooth pairing mode; and the network connection device turns on the Bluetooth pairing mode in accordance with the mode request message to passively accept Bluetooth pairing with the wearable device. That is, the network connection device is set in a state where another Bluetooth device can find it within a certain period of time and when it can satisfy the pairing request. If pairing is successful, the network connection device can save information about the wearable device, including information such as a Bluetooth address and key. Further,

The pairing relationship function between the user device and the wearable device includes the following. The user device first sends the first information to the network connection device to be directed to the wearable device, and the network connection device sends the first information to the corresponding wearable device in accordance with the pairing relationship.

In one embodiment of the present invention, there is further provided another method for communicating a wearable device, which can mainly be used in a communication system as shown in FIG. 1a or FIG. 1b. The method of this embodiment of the invention is a method implemented by a user device in said system. The block diagram shown in FIG. 4 contains the following.

Step 201. The user device determines that the second Bluetooth connection between the user device and the wearable device is disconnected. In general, a communication connection between a user device and a wearable device is a Bluetooth connection. When the user device does not find the Bluetooth signal of the wearable device or the level of the detected Bluetooth signal of the wearable device is less than a certain threshold value, it is determined that the second Bluetooth connection between the user device and the wearable device is disconnected. Alternatively, in another case, when it is determined that a third communication connection has been established with the network connection device in the network to which the user device belongs, the user device can actively disconnect the second Bluetooth connection with the wearable device. Therefore, when a third communication connection is established between the user device and the network connection device, it is determined that the second Bluetooth connection with the wearable device is disconnected.

It should be understood that after the user device detects that the second Bluetooth connection with the wearable device is disconnected, then if the first Bluetooth connection is established between the network connection device and the wearable device, the user device may perform step 202. More specifically.

The user device may actively prompt the network device to establish the first Bluetooth connection with the wearable device. More specifically, the user device can send the launch command to the network connection device, wherein the launch command is used to indicate to establish the first Bluetooth connection between the network connection device and the wearable device, so that the user device may not directly communicate with the wearable device using the network device connections. Therefore, the user device considers that a first Bluetooth connection is established between the network connection device and the wearable device, and performs the next step 202. In another case, The first Bluetooth connection between the network connection device and the wearable device is started by the wearable device. After the first Bluetooth connection with the wearable device is established, the network connection device can send a notification message to the user device, and the notification message is used to notify the user device that the first Bluetooth connection between the network connection device and the wearable device is established, so that the user device can carry out the subsequent step 202 in accordance with the notification message. When the user device actively prompts the network connection device to establish the first Bluetooth connection with the wearable device, after the user device sends a start command,

Step 202. When the user device contains information that needs to be sent to the wearable device, the user device sends the first information to the network connection device through a third communication connection with the network connection device in the network to which the user device belongs, so that the network connection device can forward the first information to the wearable device via the first Bluetooth connection.

More specifically, a third communication connection between the network connection device and the user device can support the connection in accordance with the Internet Protocol (IP), so that the user device can send the first information to the network connection device using the Internet protocol. More specifically, the first information in the format of the Bluetooth protocol is transferred in the payload of the IP packet and sent to the network connection device; or the user device sends the first information in a higher layer protocol format to the network connection device using the IP packet, and the higher layer protocols are, among other things, UPnP, DLNA, IGRS, HTTP and TCP.

The third communication connection may further be a connection that supports the universal plug and play protocol and the user device sends the first information to the network connection device using the universal plug and play protocol. More specifically, the first information in UPnP protocol format is sent to a network connection device. Alternatively, the third communication connection may be a connection that supports the Wi-Fi protocol, and the user device sends the first information to the network connection device using the Wi-Fi protocol. More specifically, the first information in the format of the Bluetooth protocol is transferred in the payload of the MAC frame of the Wi-Fi protocol and sent to the network connection device;

The first information sent by the user device may be the content, command, data, and the like that the user device sends to the wearable device, and the format of the first information sent by the user device to the network connection device may be the same or different from the format of the first information directed a network connection device to a wearable device. When the user device sends the first information to the network connection device, the communication protocol format supported by the third communication connection can be used; and when the network connection device sends the first information to the wearable device, they mainly use the Bluetooth protocol format. Hence, in a specific operation, the network connection device may convert the first information in the format of a communication protocol supported by the third communication connection into the first information in the format of the Bluetooth protocol. The method, in particular that implemented by the network connection device, is discussed in the above description of this embodiment of the invention. Details will not be described here.

Further, the user device may receive, using the network connection device, the second information sent by the wearable device. The network connection device receives second information that is sent by the wearable device through the first Bluetooth connection, the second information may be a notification or data that is sent by the wearable device to the user device, information about which the wearable device reports to the user device, or the like. The network connection device sends the second information to the user device through a third communication connection with the user device. The format of the second information sent by the wearable device to the network connection device may be the same or different from the format of the second information,

Further, when any of the conditions occurs, the user device can establish a second Bluetooth connection with the wearable device, and the user device sends the first information to the wearable device through the second Bluetooth connection.

The user device finds the Bluetooth signal of the wearable device. For example, the user device detects that the Bluetooth signal level of the wearable device reaches a certain threshold value.

After disconnecting the third communication connection between the user device and the network connection device, the user device finds the Bluetooth signal of the wearable device.

After the user device has received the second notification message sent by the network connection device, wherein the second notification message is used to notify the user device of disconnecting the first Bluetooth connection between the network connection device and the wearable device, the user device finds the Bluetooth signal of the wearable device.

When the user device finds the Bluetooth signal of the wearable device and when the user device does not interact with the wearable device using the network connection device at a set time, the user device sends a request to disconnect the first Bluetooth connection to the network connection device.

You can understand that in the method of this embodiment, if the second Bluetooth connection between the user device and the wearable device is disconnected, then the first Bluetooth connection between some network device for the user device and the wearable device can be established. When the user device detects that the second Bluetooth connection with the wearable device is disconnected, the user device can send the first information to the wearable device using the network connection device. Thus, indirect communication between the user device and the wearable device is implemented using a network connection device, so that the user device and the wearable device can communicate with each other without limiting the communication range.

It should be understood that the communication method in steps 201 and 202 is a communication method that is used after configuring devices in a communication system; however, prior to step 201, the user device may separately configure the wearable device and the network connection device, in particular as follows.

(1) The user device directly and separately configures, for the network connection device and the wearable device, the information required for the first Bluetooth communication between the network connection device and the wearable device.

The user device may send the first configuration information to the network connection device, wherein the first configuration information comprises a Bluetooth address of the wearable device and a key for Bluetooth communication between the network connection device and the wearable device; and may further comprise a pairing relationship between the user device and the wearable device, such that the network connection device stores the first configuration information. And the user device can send the third configuration information to the wearable device, while the third configuration information contains the Bluetooth address of the network connection device, and may further include information such as a key for communicating between the network connection device and the wearable device.

Further, the user device may further send the second configuration information to the network connection device, wherein the second configuration information contains Bluetooth service information that the wearable device supports. Therefore, the network connection device can establish, in accordance with the second configuration information, a mapping relationship between the Bluetooth service information and the service information that is supported by the third communication connection, and can save the mapping relationship.

(2) The user device does not directly and separately configure the function of the network connection device and the function of the wearable device, so that the network connection device can actively initiate the Bluetooth pairing procedure with the wearable device, and the wearable device can be passively paired with the network connection device.

The user device sends a mode request message to the wearable device, while the mode request message is used to request the wearable device to enable Bluetooth pairing mode; that is, the wearable device is set to a state where another Bluetooth device can find it within a certain period of time, and the wearable device can satisfy the pairing request. The user device sends a procedure request message to the network connection device, wherein the procedure request message is used to request the network connection device to enable the Bluetooth pairing procedure with the wearable device.

Alternatively, the user device sends the procedure request message only to the network connection device, while the procedure request message is used to request the network connection device to enable the Bluetooth pairing procedure, instead of sending the procedure request message to the wearable device to enable the Bluetooth pairing mode. The wearable device is pre-configured to enable pairing mode, that is, it is pre-configured to the state when another Bluetooth device can find it and when the wearable device can satisfy the pairing request. During pairing, the wearable device may ask the user whether to accept pairing with the network connection device. After the user agrees to pair with the network connection device,

(3) The user device does not directly and separately configure the function of the network connection device and the function of the wearable device, so that the wearable device can actively initiate the Bluetooth pairing procedure with the network connection device, and the network connection device can be passively paired with the wearable device.

The user device sends a mode request message to the network connection device, wherein the mode request message is used to request the network connection device to enable the Bluetooth pairing mode; that is, the network connection device is set to a state where another Bluetooth device can find it within a certain period of time, and the wearable device can satisfy the pairing request. The user device sends a procedure request message to the wearable device, wherein the procedure request message is used to request the wearable device to perform the Bluetooth pairing procedure with the wearable device.

The communication method of a wearable device proposed in the present invention is described below using some variant embodiment of the invention. In the communication system of this embodiment of FIG. 1a, a user device communicates with a network device using UPnP, a network device communicates with a wearable device using Bluetooth, and a user device communicates with a wearable device using Bluetooth. In this embodiment, the following is performed.

1. The user device configures the network connection device and the wearable device. The block diagram shown in FIG. 5a contains the following.

(1) The user device receives the Bluetooth address BD_ADDR1 of the network connection device and the Bluetooth address BD_ADDR2 of the wearable device and generates a Link_Key key for Bluetooth communication between the network connection device and the wearable device.

More specifically, the user device can obtain, using the web client installed on the user device, the Bluetooth address BD_ADDR1 of the network connection device from the web server, that is, the network connection device; or the user device serves as a management point and reads the Bluetooth address BD_ADDR1 from the network connection device (the network connection device is used as the UPnP device) using the UPnP protocol.

(2) The user device sends information such as the BD_ADDR1 address of the Bluetooth device of the network connection and the Link_Key to the wearable device for storage.

(3) The user device sends information such as the Bluetooth address BD_ADDR2 of the wearable device and the Link_Key to the network connection device for storage. If desired, the user device sends information such as the pairing relationship between the user device and the wearable device to the network connection device for storage.

If the network connection device does not accept the pairing relationship between the user device and the wearable device, then it establishes the pairing relationship between the user device and the wearable device.

(4) The user device receives Bluetooth service information that the wearable device supports from the wearable device and sends the Bluetooth service information to the network connection device.

Therefore, the network connection device can establish a mapping relationship between the Bluetooth service information that the wearable device supports and the UPnP service information, and map the wearable device to the root device UPnP of the network connection device. For example, the network connection device establishes a mapping relationship between the UPnP protocol configuration management service information (CMS) and the HEART RATE SERVICE information of the heart rate supported by the wearable device, which is more specifically described below.

A. Match the Bluetooth address of the wearable device with the universal unique identifier (UUID) of the UPnP root device.

B. Establish a mapping relationship between the function (action) and the event in the CMS and GATT service and the characteristics command (CHARACTERISTIC) in the Bluetooth protocol, an example of the above is given below.

The function (SetValues) of setting values ​​in the CMS corresponds to the request (Write Request) for recording in the Bluetooth protocol; the function (GetValues) of receiving values ​​in the CMS corresponds to the request (Read Request) for reading in the Bluetooth protocol; and a CMS report event corresponds to a Handle Value Notification of a value in the Bluetooth protocol and the like.

C. Establish a mapping relationship between the characteristic (CHARACTERISTIC) in the Bluetooth protocol and the parameter in the CMS service data model, the following is an example of the above.

Features in the Bluetooth protocol, including the measured value of the heart rate, the configuration descriptor of the client heart rate characteristic, the location of the sensor installed on the body, the heart rate monitoring point and the like, are considered as parameters in the CMS data model.

D. Establish a matching relationship between a feature that has a Notify attribute in the Bluetooth protocol and reflects the state of the variable in the CMS, so that the wearable device can send the value of the characteristic in the form of a report, an example is mentioned below.

The measured value of the heart rate in the Bluetooth protocol corresponds to the state-reflecting variable of the UPnP protocol.

2. The user device does not directly communicate with the wearable device using the network connection device. The block diagram shown in FIG. 5b contains the following.

(1) In the process of Bluetooth communication between the user device and the wearable device, if the wearable device does not receive, within a certain period of time, the Bluetooth heart rate packet sent by the user device, then it is determined that the Bluetooth connection between the wearable device and the user device is disconnected device. In this case, the wearable device continues to determine whether a Bluetooth paging message sent by the network connection device can be received. If the Bluetooth paging message sent by the network connection device can be received, the wearable device can return a Bluetooth paging response to establish a Bluetooth connection between the network connection device and the wearable device.

In another specific embodiment of the invention (as shown by dashed lines in FIG. 5b), if the user device does not receive, within a certain period of time, a Bluetooth response message that contains the heart rate and which directs the wearable device, then it is determined that the connection The Bluetooth with the wearable device is disconnected, and the user device sends a launch command to the network connection device using UPnP protocol to induce the device to network connection tions to establish a Bluetooth connection with a wearable communication device.

(2) After establishing a Bluetooth connection between the network connection device and the wearable device, a notification message is sent to the user device, and the notification message is used to notify the user device that the first Bluetooth connection between the network connection device and the wearable device is established, or that the wearable device is in a connected state. For example, a notification message is used to notify the user device that the UPnP root device corresponding to the wearable device is in a connected state, and the notification message is, in particular, the SSDP :: alive service discovery Simple Message Protocol (SSDP) message.

(3) After receiving the SSDP :: alive notification message sent by the network connection device, the user device may not directly communicate with the wearable device, more specifically, as follows.

The user device sends the first information to the network connection device using the UPnP protocol and the network connection device converts the first information sent using the UPnP protocol to the first information sent using the Bluetooth protocol and sends the first information to the wearable device. For example, the first information sent by a user device to a wearable device is to read a parameter value. The user device sends the UPnP protocol GetValues ​​() command to the network connection device and the network connection device converts the GetValues ​​() command to the Bluetooth protocol Read Request () and sends the Read Request () to the wearable device.

When the wearable device sends the second information to the user device, the wearable device sends the second information to the network connection device using the Bluetooth protocol and the network connection device converts the second information sent using the Bluetooth protocol to the second information sent using the UPnP protocol and sends the second information to the user device. For example, the second information sent by the wearable device to the user device is a heart rate report. The wearable device sends the value of the heart rate parameter to the network connection device using the Bluetooth Handle Value Notification () message,

(4) When the user device detects that the Bluetooth signal level of the wearable device reaches a certain threshold value, the user device tells the network device to disconnect the Bluetooth connection with the wearable device so that the user device can communicate with the wearable device by establishing a direct communication connection.

The communication method of a wearable device proposed in the present invention is described below using another specific embodiment of the invention.
