Technical Field

[0001] The present disclosure relates to the field of Internet of Things, and more specifically, to a method, apparatus, Internet of Things device, voice management platform, Internet of Things system, and computer-readable storage medium for performing voice control in the field of Internet of Things. Background Art

[0002] As an important branch of the Internet of Things (IoT), Narrow Band Internet of Things (NB-IoT) is receiving more and more research and application to meet the booming IoT business needs. NB-IoT is built on cellular networks. It uses half-duplex communication to support cellular data connections of low-power devices in wide area networks, and only consumes about 180kHz of bandwidth for data transmission. In addition, NB-IoT can be directly deployed on GSM networks, UMTS networks or LTE networks, thereby reducing deployment costs and smoothing network upgrades. Due to the low power consumption of NB-IoT, the battery life of NB-IoT devices may be increased by at least 10 years, thereby supporting efficient connections of devices with long standby time and high network connection requirements. In addition, NB-IoT can also provide very comprehensive indoor cellular data connection coverage.

[0003] With the advent of the era of smart cities and big data, wireless communications will connect everything. At present, a large number of things have been connected, but most of these connections are carried out through short-range communication technologies such as Bluetooth and Wi-Fi, and do not need to go through the operator's mobile network. However, in order to meet the needs of different IoT services, according to the characteristics of IoT services and mobile communication networks, in actual applications, telecommunication networks and sensor networks are used in a variety of IoT application scenarios.

[0004] The IoT architecture built on the cellular network includes the perception layer, network layer and application layer. The IoT terminal located in the perception layer is a device that connects the perception layer and the network layer in the IoT, collects data and sends data to the network layer. It is responsible for multiple functions such as data collection, preliminary processing, encryption, and transmission. The IoT gateway located in the perception layer can aggregate and forward data from the IoT terminals, and can also distribute data from the application layer to the IoT terminals. The transport layer can include existing transport networks such as 3G, 4G, and LTE networks. The application layer can implement various upper-layer intelligent applications, such as urban management, telemedicine, smart homes, etc.

[0005] In the R14 version of the NB-IoT standard evolution, the underlying protocol does not support voice transmission, and due to bandwidth limitations, voice transmission is also very difficult, which makes it difficult to transmit any voice in NB-IoT, and thus difficult to perform any voice control.

In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0029] First, refer to Figure 1 A schematic diagram of the structure of the NB-IoT system 100 according to an embodiment of the present disclosure is described.

[0030] In the NB-IoT system 100, one or more IoT terminals 110 supporting NB-IoT technology can be connected to the cellular base station 130 via the IoT gateway 120, and then connected to the IP network 140 through the cellular base station 130, so as to interact with the remote platform and application 150. The IoT terminal 110 can report the collected data to the remote platform and application 150 via the IoT gateway 120, the cellular base station 130 and the IP network 140, so that the remote platform and application 150 can analyze and process the data. The remote platform and application 150 can also send instructions to the IoT terminal 110 via the IP network 140, the cellular base station 130 and the IoT gateway 120 to request it to collect data or perform other operations.

[0031] The IoT terminal 110 may have an eSIM (embedded SIM) card that supports storage functions and can run an operating system, so that the steps performed by the IoT terminal 110 in the method according to the embodiment of the present disclosure can be implemented in the eSIM card. Of course, these steps can also be implemented in other components of the IoT terminal 110, such as in a chip specifically used to implement the method. The IoT gateway 120 has NB-IoT communication capabilities and device management capabilities, can manage the IoT terminal 110, and can also forward data received from and from the IoT terminal 110. The remote platform and application 150 are related to various IoT services and can perform device management, status query, positioning query, etc.

[0032] exist Figure 2 A schematic diagram of an architecture example of a NB-IoT system according to an embodiment of the present disclosure is shown in the figure.

[0033] like Figure 2 As shown, the UE as the IoT terminal 110 can carry the service data that needs to be reported to the CloT service as the remote platform and application 150 through the wireless signaling message. The wireless signaling message carrying the service data is transmitted to the SCEF (Service Capability Exposure Function) via the MME (Mobility Management Element) in the core network, and then transmitted to the CloT service by the SCEF.

[0034] The current NB-IoT system does not support voice transmission, so it is impossible to transmit voice information between the IoT terminal and the remote platform and application to perform corresponding operations. The disclosed embodiment introduces the XMPP protocol that can asynchronously and quickly exchange short texts at the application layer of the protocol stack, so that the input voice can be encoded through the XMPP protocol, and then by adding a label indicating that the encoded data is voice, the network device in the NB-IoT can be instructed to use the XMPP protocol to decode the encoded data and perform corresponding operations.

[0035] Figure 3 FIG. 3 is a flowchart of a method 300 for voice control according to an embodiment of the present disclosure. The IoT device 310 in the method 300 may be an IoT terminal 110 or an IoT gateway 120. The IoT device 310 may be connected to a voice management platform 320 via a base station, an MME, and a SCEF. The voice management platform 320 may be Figure 1 remote platform and at least a portion of the application 150 and is deployed on Figure 2 The voice management platform 320 may be composed of one or more servers, which may perform IoT services such as remote control and data collection in a distributed or centralized control manner.

[0036] In S310 , the IoT device 310 encodes the input voice using the XMPP protocol to obtain encoded data.

[0037] According to an embodiment of the present disclosure, since the XMPP protocol supports BASE64 encoding technology, the audio file obtained by recording the input voice can be first converted into a binary file, and then the binary file is encoded into a string through BASE64 to obtain the encoded data of the input voice.

[0038] In S320 , the IoT device 310 assigns a tag to the encoded data indicating that the encoded data is speech.

[0039] For example, in the wireless signaling message that the IoT device 310 is about to send to the voice management platform 320, a subnode consisting of one or more fields can be added, and a tag with a predetermined value can be set in the head of the subnode to indicate that the data contained in the subnode is voice data, and the data part of the subnode can carry the encoded data obtained by S310 encoding. For example, the encoded data can be set in the stringValue of the subnode as the node value, and the tag can be set in the message type messageType, so that the data in the stringValue can be extracted according to the tag, and it can be determined according to the tag that the data is encoded using the XMPP protocol. It can be used Figure 4The example of program code shown is used to implement voice in the XMPP protocol.

[0040] In S330, the IoT device 310 sends the encoded data and the assigned tag together to the voice management platform 320 that supports the XMPP protocol, so that the voice management platform 320 decodes the encoded data using the XMPP protocol according to the tag, and controls other IoT devices according to the operation corresponding to the decoded data obtained by decoding.

[0041] For example, the IoT device 310 can first convert the wireless signaling message carrying the sub-nodes such as in S320 into a data stream suitable for transmission on NB-IoT, and then send it to the voice management platform 320 through the base station, MME and SCEF. The voice management platform 320 can be at least a part of the CIoT service, or a system independent of the CIoT service. Since the voice data is transmitted through the SCEF network element in a non-IP transmission mode, the voice data is prevented from being exposed to the IP network, thereby improving the security of voice transmission.

[0042] The voice management platform 320 is a system that can control the IoT device according to the voice information and / or can receive the voice information to perform the corresponding operation. The voice management platform 320 can be implemented based on the JABBER server, so that the XMPP protocol can be supported. In the voice management platform 320 or in the device that the voice management platform 320 can access, the association relationship between the predetermined data and the predetermined operation can be stored. When the voice management platform 320 receives the message, if the voice management platform 320 detects that one of the multiple sub-nodes contained in the message carries a label indicating that the associated data is voice, then the voice management platform 320 determines that the data carried by the sub-node is voice data that needs to be decoded by the XMPP protocol, so the data is decoded using BASE64 to obtain decoded data. Then, the voice management platform 320 uses the decoded data to find the above-mentioned association relationship, thereby determining what operation needs to be performed (for example, requesting the IoT terminal to collect humidity information at predetermined intervals, requesting the IoT terminal to turn on the chemical concentration detection function, etc.) and performing the operation, thereby achieving the purpose of control based on voice input.

[0043] Figure 5 Detailed description is given in FIG. 5 , which is a flowchart of a method 500 for performing voice control according to an embodiment of the present disclosure.

[0044] In S510 , the IoT device 310 receives a message sent by the voice management platform 320 , including the encoded data and a tag indicating that the encoded data is voice.

[0045] Such data and tags may be carried in a subnode containing one or more fields in the message. The voice coding data carried in the subnode may be received from other IoT devices or directly input into the voice management platform 320 by the user. If such data is directly input into the voice management platform 320 by the user, the voice management platform 320 may convert the input voice into coded data through BASE64 in the manner of S310.

[0046] The message containing voice coding data and tags that the voice management platform 320 is going to send to the IoT device 310 can first be converted into a data stream suitable for transmission on NB-IoT, so that it can be sent to the IoT device 310 through the SCEF network element without passing through the packet data network. This can prevent the voice command from being exposed in the IP network, thereby improving the security of voice transmission.

[0047] In S520 , the IoT device 310 decodes the encoded data using the XMPP protocol according to the tag.

[0048] Since the tag indicates that the encoded data is voice, the IoT device can decode the data using the XMPP protocol used to encode the voice, thereby obtaining decoded data.

[0049] In S530, an operation corresponding to the decoded data is performed according to the decoded data obtained by decoding.

[0050] An association relationship that is the same as the association relationship between data and operations that can be used by the voice management platform 320 can be stored in the IoT device 310 or in a device that the IoT device 310 can access, so that the IoT terminal 310 can look up the association relationship based on the decoded data to determine what operation should be performed (for example, periodically uploading collected humidity information, turning on a chemical concentration detection function, etc.) and perform the operation, thereby achieving the purpose of control based on voice input.

[0051] exist Figure 6 6 is a flowchart of a method 600 for performing voice control according to an embodiment of the present disclosure.

[0052] In S610 , a user inputs a voice from an IoT terminal such as a smart phone.

[0053] In S620, the IoT terminal encodes the input voice using the XMPP protocol, for example, the voice data recorded as a voice file can be converted into a binary stream using the BASE64 technology. For example, the user can input a voice "report the temperature", and the IoT terminal that receives the voice can convert the voice into a binary stream based on the BASE64 technology.

[0054] In S630, the IoT terminal assigns a predetermined tag (e.g., 01111110) to the voice coding data to indicate that the corresponding data is voice data, and adds the voice coding data and the predetermined tag as a sub-node to a message that needs to be sent to the voice management platform as a remote application and platform. Alternatively, the voice coding data and the predetermined tag may also be sent to the voice management platform as a single message.

[0055] In S640, the message to be sent is converted into a data stream suitable for transmission on NB-IoT according to the existing NB-IoT technology.

[0056] In S650, the IoT terminal sends the data stream to the SCEF network element via the IoT gateway, the cellular base station, and the core network of the cellular network. This transmission method can prevent messages carrying voice information from passing through the packet data network, thereby enhancing the security of voice information transmission.

[0057] In S660, the SCEF network element forwards the data stream to the voice management platform. After the voice management platform identifies the predetermined tag, it determines that the data associated with the tag is voice data, and then decodes the associated data using the XMPP protocol. Next, the voice management platform searches the database that stores the association between data and operations based on the decoded data, and determines the operation to be performed based on the decoded data. In this example, after the voice management platform searches the database based on the decoded data, it determines that the operation corresponding to the decoded data is to request the IoT terminal to send temperature information.

[0058] In S670, the voice management platform sends the request message to the Internet of Things gateway via the SCEF network element, the core network, and the cellular base station. Alternatively, the voice management platform can also send the request message to the Internet of Things gateway via the IP network.

[0059] In S680, the IoT gateway parses the request message to determine the operation it needs to perform. For example, in this example, the IoT gateway determines that it needs to instruct the IoT terminal to upload the collected temperature data based on the request message, and then sends a message instructing to upload the temperature data to the IoT terminal, so that the IoT terminal performs the corresponding operation.

[0060] Alternatively, in other embodiments, when the IoT gateway determines that the request message is not a request for it to perform an operation, it directly forwards the request message to the IoT terminal, so that in S680, the IoT terminal parses the request message to determine the operation to be performed. For example, in this example, the IoT terminal reports the collected temperature data to the voice management platform.

[0061] The above example is explained by taking the example of a user inputting voice from an IoT terminal. Those skilled in the art will understand that voice can also be input from an IoT gateway or a voice management platform. In the case where the voice is input from an IoT gateway, the IoT gateway encodes the input voice and adds a predetermined tag, and then sends it to the voice management platform. In the case where the voice is input from a voice management platform, the voice management platform encodes the input voice and adds a predetermined tag, and then sends it to the IoT gateway or terminal. In the IoT gateway or terminal or in a device accessible to it, the association between data and operations is stored, so that the IoT gateway or terminal can determine the operation to be performed based on the decoded data.

[0062] In addition, the above example is described by taking the reporting temperature as an example. Those skilled in the art can understand that other operations can also be controlled by voice, for example, controlling the IoT gateway to broadcast certain data, controlling the IoT gateway or terminal to report its own status, etc. In another example, the switch of the smart street lamp can be controlled by voice input. The user can input a voice command to the IoT gateway. After receiving the voice command, the IoT gateway encodes the voice through the BASE64 technology supported by the XMPP protocol, adds a predetermined tag associated with it, and then performs protocol conversion on the resulting data stream to convert it into data that can be recognized by the wireless transmission network. These operations can be performed in the eSIM module of the IoT gateway. Then, the physical network gateway sends the protocol-converted data to the eNB, and the eNB transmits it to the CIoT service through the SCEF network element. Then, the CIoT service is responsible for the conversion of the signaling coded data, converts the received data into the BASE64 code supported by the XMPP protocol, and then transmits it to the voice management platform implemented based on the JABBER server. After receiving the information, the voice management platform reverses the SCEF network element and distributes the reverse command to the smart street lamp as the IoT terminal via the downlink DL-DCH channel to perform the switch operation.

[0063] The above describes the method for voice control according to the embodiment of the present disclosure. Figures 7 to 9 A structural block diagram of a device or system according to an embodiment of the present disclosure is described.
