Detailed Description

In order to make the aforementioned objects, features and advantages of the present application more comprehensible, the present application is described in further detail with reference to the accompanying drawings and the detailed description.

The embodiment of the application provides a method and a device for communication among equipment, wherein a server can distribute different sessions for a gateway and sub-equipment connected with the gateway, so that communication messages of the gateway and the sub-equipment connected with the gateway are forwarded to the server through the same physical channel, and the server transmits the communication messages among service platforms based on different sessions. The communication message is message data of the device, and may include various types of information, such as service information, device state information, and the like, where the service information may be determined based on a service of the corresponding device, for example, the service information of the lighting device is a lighting on/off instruction, and the service information of the access control system is a locking or unlocking instruction.

As shown, a communication system includes: server 10, gateway 20, sub-devices 30, and service platform 40, wherein the gateway may connect one or more of the sub-devices. One side where the gateway and the sub-device are located is called an equipment side, one side where the server and the service platform are located is called a service side, data are transmitted between the equipment side and the service side through the same physical channel between the gateway and the sub-device connected with the gateway and the server, and different session communication is adopted for the gateway and the sub-device between the server of the service side and the service platform, so that the server can distinguish the gateway and the sub-device connected with the gateway based on the session.

The sub-equipment comprises the Internet of things equipment, the Internet of things equipment is connected with the server through the gateway if needed, and the sub-equipment is lighting equipment, security equipment and the like. The Gateway (Gateway) may be used for both wide area network interconnection and local area network interconnection, may be used between two systems with different communication protocols, data formats or languages, and even completely different architectures, and may be regarded as a translator.

Referring to fig. 2, a schematic diagram of inter-device communication is shown.

Step 202, the gateway receives a network access request of the child device. The kid device may request access to the network and may send a network request to the gateway.

And step 204, the gateway generates a binding request based on the network access request, and sends the binding request through the physical channel.

Step 206, allocating a first session to the child device of the gateway according to the binding request, and binding the child device and the physical channel of the gateway. The server can carry out validity verification such as authentication processing and the like on the sub-equipment based on the binding request, after the sub-equipment is confirmed to be legal, a first session can be distributed to the sub-equipment, and the sub-equipment and the physical channel of the gateway are bound, so that the server and the service platform can interact communication messages of the sub-equipment through the first session, the gateway and the sub-equipment share the same physical channel, namely, the gateway transmits data of the gateway and the sub-equipment through the physical channel.

Step 208, the server generates a binding response and feeds back the binding response to the gateway through the physical channel. The gateway confirms that the sub-device is successfully bound, and subsequently can forward the communication message of the sub-device to the server, so that the communication message is forwarded to the service platform through the server.

For each network-accessing sub-device, the physical channels of the sub-device and the gateway can be bound at the server based on the binding request, and the first session is allocated to the sub-device, so that the communication messages of the server for different sub-devices can be transmitted through different sessions without knowing the topological connection of the gateway and the sub-device.

In this embodiment, the server may further allocate a physical channel and a session to the gateway when the gateway requests a connection, that is, when the gateway wants to access the communication system, generate a connection request, and send the connection request to the server. Then the server can carry out validity verification, such as authentication processing and the like, on the gateway based on the connection request of the gateway, and can allocate a second session to the gateway after the gateway is confirmed to be valid, so that the server and the service platform can interact with the communication message of the gateway through the second session; a physical channel is also assigned to the gateway so that communications between the gateway and the server occur over the physical channel. And the server generates a connection response and sends the connection response so as to feed back the physical channel through the connection response.

In summary, the gateway and the sub-devices thereof share the same physical channel, wherein the data of the sub-devices is forwarded by the gateway, and the server further establishes sessions for the gateway and the sub-devices respectively, so that the server does not need to pay attention to the topological relationship between the gateway and the sub-devices, and the server can transmit data directly based on the session and the service platform. Different sub-devices can be accurately distinguished, and the structure is flexible and the expandability is strong.

In an alternative embodiment of the present application, the present application may be applied to a distributed communication system, where different servers may be implemented by the same or different servers, for example, one server is used to perform communication with a gateway, legal verification of a device, session allocation, and the like, and may also be implemented by multiple servers, for example, where the servers include: the system comprises an access server, an authentication server and a session server. The access server (access server) is a front-end server responsible for connection, and may use various protocols for communication, such as MQTT (Message Queuing Telemetry Transport) Protocol, CoAP (Constrained Application Protocol), HTTP (hypertext transfer Protocol), and the like. The authentication server is used for authenticating the gateway and the sub-equipment of the access system, and can also avoid the unauthorized of the message, such as the message of the fake sub-equipment forwarded by the gateway can be refused. The session server is used for taking charge of the routing relationship of the session in the communication system, and usually uses distributed storage, such as Hbase, etc., so that the access server mounted by the session server can be quickly found through one piece of device information (such as device ID), for example, the access server can be found by using the session during the downlink transmission of the message.

A distributed communication system architecture is shown in fig. 3. The communication information includes: the gateway g1, the gateway g2 and the gateway g1 are connected with the sub-device d1 and the sub-device d2, and the gateway g2 is connected with the sub-device d3, the sub-device d4 and the sub-device d 5. The gateway g1 and the gateway g2 are respectively connected with an access server AS of the service end, the access server AS is connected with an authentication server CS and a session server SS, and the access server AS is also connected with a service platform BP. The interaction between the devices in the communication system is shown in fig. 4 and 5.

Wherein the connection interaction process is shown in fig. 4.

Step 402, the gateway generates a connection request and sends the connection request to the access server. E.g., gateway g1, may access the communication system through the access server, gateway g1 may generate a corresponding connection request to send to the access server.

Step 404, the access server obtains the authentication information of the gateway from the connection request, and forwards the authentication information to the authentication server. The authentication information of the gateway may be used as the first authentication information.

Step 406, the authentication server authenticates the gateway based on the authentication information of the gateway, and feeds back an authentication result, including success or failure. If authentication fails, the access server may deny access to the gateway.

Step 408, for the feedback of successful authentication, the access server sends a session generation request to the session server.

Step 410, the session server generates a second session, establishes a mapping relationship between the second session and the gateway information of the gateway, and feeds back the mapping relationship. The session server assigns a second session s2 for the gateway g1 and then establishes the mapping g1-s 2.

Step 412, the access server allocates a physical channel to the gateway, and binds the gateway information of the gateway with the physical channel. I.e. the gateway g1 is assigned a physical channel c1, thus binding g1-c 1.

In step 414, the access server generates a connection response and feeds back the connection response. The connection response may be a response that the connection was successful.

At step 416, the kid device may request to log on to the gateway and may send a web request to the gateway. I.e., kid 1 sends a request to access network to gateway g 1.

Step 418, the gateway determines the authentication information of the sub-device based on the network access request, generates a binding request and sends the binding request to the access server through the physical channel.

Step 420, the access server obtains the authentication information of the sub-device from the binding request, and forwards the authentication information of the sub-device to the authentication server. The authentication information of the sub-device may be used as the second authentication information.

Step 422, the authentication server authenticates the sub-device based on the authentication information, and feeds back the authentication result, including success or failure. If the authentication fails, the access server can refuse the access and binding of the sub-equipment.

Step 424, for the feedback of successful authentication, the access server sends a session generation request to the session server.

And 426, the session server generates a first session for the sub-device, establishes a mapping relationship between the first session and the sub-device, and feeds back the mapping relationship. The session server assigns the child device d1 the first session s1 and then establishes the mapping d1-s 1.

In step 428, the access server binds the device information of the sub-device with the physical channel of the corresponding gateway. I.e., binding the physical channel c1, i.e., d1-c1, to the child device d 1.

Step 430, the access server generates a binding response and feeds back to the gateway through the physical channel. The binding response may be a response that the binding was successful.

And step 432, the gateway generates a network access response and feeds the network access response back to the child equipment, and the network access can be successfully realized through the child equipment.

Therefore, the login of the gateway and the equipment in the system can be realized through the steps, and then the communication message can be transmitted through uplink and downlink. For the communication message sent by the gateway through the physical channel, a resource party of the communication message can be determined according to the resource path, the resource party is the gateway, the second session is inquired, if the resource party is the sub-device, the first session is inquired, and then the communication message is forwarded to the service platform through the inquired session (the first session or the second session).

For the convenience of distinguishing, the communication packet sent by the sub-device to the service platform is referred to as an uplink communication packet, and the communication packet sent by the service platform to the sub-device is referred to as a downlink communication packet. The interaction process of the communication message is as shown in fig. 5.

Step 502, the sub-device sends an uplink communication message to the gateway. The communication between the sub-devices and the gateway can be realized based on various communication modes, such as Bluetooth and WIFI.

Step 504, the gateway encapsulates the uplink communication packet of the sub-device, and then forwards the uplink communication packet to the access server through the physical channel. The encapsulation mode can be set according to requirements, such as encapsulation and forwarding according to protocols such as MQTT, CoAP, HTTP and the like. In which, the device information may be carried in the resource path during the encapsulation process, thereby facilitating the access server to query the session, for example, the resource path is TOPIC, URI, or the like. In this example, after receiving the uplink communication packet through the physical channel c1 of the gateway g1, the access server determines that the resource side is the sub-device d1 according to the TOPIC, queries the mapping relationships d1-s1, and determines that the first session s1 needs to be invoked.

Step 506, the access server determines the sub-device to which the uplink communication packet belongs according to the resource path of the uplink communication packet, and queries the first session of the sub-device.

Step 508, the access server forwards the uplink communication packet to the service platform through the first session.

Step 510, the service platform determines a first session according to the sub-device to which the sent downlink communication message belongs, and sends the downlink communication message to the access server through the first session.

Step 512, the access server determines the sub-device to which the downlink communication packet belongs according to the first session, and determines a physical channel of a gateway bound by the sub-device. The access server queries the mapping relation d1-s1 to determine the sub-device d1 according to the first session s1, and then queries the physical channel c1 according to the binding relation d1-c 1.

Step 514, the access server forwards the downlink communication packet to the gateway through the physical channel. That is, the downlink communication message is sent to the gateway g1 through the physical channel c 1.

In step 516, the gateway determines the sub-device corresponding to the downlink communication packet and forwards the downlink communication packet to the sub-device.

The access server and the gateway may transmit a TCP (Transmission Control Protocol) message, where the message may include one or more Protocol-encapsulated communication messages, so that the TCP message may be split into communication messages, or a plurality of TCP messages may form a communication message, which is specifically determined according to the settings of the communication messages and the TCP messages.

In this application embodiment, communication message can be confirmed according to specific thing networking device, for example, to the fluorescent tube system, communication message can include light on, off information, the temperature information of bulb etc. to the security protection system, communication message can include the on, off information of lock etc..

In the embodiment of the application, the corresponding logical session is inquired by using the resource paths such as TOPIC of the communication message or URI of the HTTP, so that the forwarding can be realized without invading the service message. Compared with the existing gateway forwarding device message mode that fields need to be encapsulated and defined according to the negotiated data format, the embodiment of the application does not limit the data format, the gateway can directly transmit the communication message, only a legal resource path needs to be constructed, and the method is simple and convenient to operate and high in efficiency.

Referring to fig. 6, a flowchart illustrating steps of a gateway in an embodiment of an inter-device communication method in the present application is shown, which specifically includes the following steps:

step 602, a connection request is sent to a server.

The gateway may connect to the server for accessing the communication system, and therefore, the gateway may generate a corresponding connection request, which may include authentication information, such as a signature, and the like, and may also include device information, such as a device name, a device identification (Identity, ID), and the like, and then send the connection request to the server. For example, the communication gateway may assign information for authentication to a legitimate gateway and a legitimate sub-device, such as assigning a device name devicename and a device key devicecret to each device, and may calculate signature data based on the information for authentication, and add the signature data as authentication information to the connection request.

Step 604, receiving a connection response fed back by the server, and determining a physical channel according to the connection response. The physical channel is used for transmitting communication messages, and the communication messages comprise communication messages of a gateway and communication messages of the sub-equipment.

Step 606, receiving the network access request of the sub-device.

Step 608, generating a binding request according to the network access request, and sending the binding request to a server through the physical channel.

The kid device may request access to the network and may send a network request to the gateway. The gateway generates a binding request based on the network access request, the binding request carries authentication information of the sub-device, such as a signature, and the like, and also carries device information of the sub-device, such as a device name, a device ID, and the like, and then the binding request can be sent through the physical channel.

And step 610, receiving a binding response returned by the server through the physical channel.

For a gateway and its connected sub-devices, the server establishes a physical channel and a session for each device, so that the gateway and the server interact through the physical channel, and the server forwards the communication messages of different devices to the service platform by adopting different sessions. The topological relation of the gateway and the sub-devices thereof can be dynamically adjusted, for example, the sub-device d1 can be hung on the gateway g1, and can also be hung on the gateway g2 after the gateway g1 is offline, so that the flexibility and the expandability of the device side are improved.

Referring to fig. 7, a flowchart illustrating steps of a server in an embodiment of an inter-device communication method according to the present application is shown, which specifically includes the following steps:

step 702, receiving a connection request of a gateway, allocating a physical channel to the gateway according to the connection request, and binding a second session.

Step 704, generating a connection response and sending, so as to feed back the physical channel through the connection response.

The server can carry out validity verification such as authentication processing and the like on the gateway based on the connection request of the gateway, and can generate a second session and bind gateway information of the gateway with the second session after the gateway is confirmed to be legal, so that the server and the service platform can interact communication messages of the gateway through the second session; the gateway is also bound to a physical channel through which communications between the gateway and the server occur.

In an optional embodiment, the authentication information of the gateway may be obtained from the connection request, and the gateway is authenticated according to the authentication information of the gateway; after the authentication of the gateway is passed, generating a second session, and establishing a mapping relation between the gateway information of the gateway and the second session; and allocating a physical channel and binding the physical channel with the gateway information of the gateway. Receiving a connection request of a gateway, authenticating the gateway according to the connection request, namely, a server can carry out validity verification before connecting the gateway, can carry authentication information of the gateway in the connection request, such as signature data, and then authenticates the gateway based on the authentication information of the gateway. For example, the communication gateway may assign information for authentication to a legitimate gateway and a legitimate sub-device, such as assigning a device name devicename and a device key devicecret to each device, and may calculate signature data based on the information for authentication. The server then obtains the signature data from the authentication information of the connection request, calculates a signature data based on the device information of the gateway, compares the obtained signature data with the calculated signature data, and determines whether the two match. If the matching is successful, the authentication is successful, otherwise, the authentication is not successful. First channel information may be bound for the gateway after the authentication of the gateway passes. If the authentication is not passed, the process can be ended, and the connection of the gateway is rejected. The server may then generate a second session and establish a mapping between the gateway information of the gateway and said second session, such as a gateway name or gateway identification and a mapping for the second session. And then, distributing a physical channel for the gateway, and binding the gateway information with the physical channel. So that the subsequent gateway can interact data with the server through the physical channel.

Step 706, receiving a binding request through the physical channel, allocating a first session to the child device of the gateway according to the binding request, and binding the child device and the physical channel of the gateway.

The server can carry out validity verification such as authentication processing and the like on the sub-equipment based on the binding request, and can generate a first session and bind the equipment information of the sub-equipment with the first session after the sub-equipment is confirmed to be legal, so that the server and the service platform can interact the communication message of the sub-equipment through the first session; the sub-devices are also bound to the physical channel so that the gateway and its sub-devices share the same physical channel. The gateway confirms that the sub-device is successfully bound, and subsequently, the gateway can forward the communication message of the sub-device to the server, so that the communication message is forwarded to the service platform through the server.

If the authentication information is signature data, the server correspondingly calculates one signature data, and then compares the acquired signature data with the calculated signature data to determine whether the two are matched. If the matching is successful, the authentication is successful, otherwise, the authentication is not successful. After the authentication of the sub-device is passed, the server may generate a first session, and establish a mapping relationship between the device information of the sub-device and the first session, such as a device name or a device identifier, and a mapping relationship corresponding to the first session. And then establishing the binding relationship between the equipment information of the sub-equipment and the physical channel, so that the physical channel is adopted for forwarding between the communication message gateway of the sub-equipment and the server.

At step 708, a binding response is generated and fed back through the physical channel.

For a gateway and its connected sub-devices, the server establishes a physical channel and a session for each device, so that the gateway and the server interact through the physical channel, and the server forwards the communication messages of different devices to the service platform by adopting different sessions. In the embodiment of the application, the gateway can record information such as the device name and the device identifier of the device, and can also locally maintain the sub-device list of the access server.

To sum up, when the sub-devices need to be connected with the gateway, a binding request can be sent to the server through the physical channel of the gateway, the server can allocate a first session to the sub-devices of the gateway according to the binding request, so that the communication messages of the sub-devices forwarded by the gateway are transmitted through the first session, and the sub-devices are bound with the physical channel of the gateway, so that the data of the gateway and the sub-devices thereof can be transmitted through one physical channel, and the server forwards the communication messages of different sub-devices through different sessions, thereby being convenient for distinguishing different sub-devices.

For the service platform, the topological relation of the gateway and the sub-devices thereof does not need to be sensed, the corresponding session of the device can be directly determined, and correspondingly, the topological relation of the gateway and the sub-devices thereof can be dynamically adjusted, for example, the sub-device d1 can be hung on the gateway g1, and can be hung on the gateway g2 after the gateway g1 is off line, so that the flexibility and the expandability of the device side are improved.

Referring to fig. 8, a flowchart illustrating steps of uplink transmission in an embodiment of an inter-device communication method according to the present application is shown, which specifically includes the following steps:

step 802, receiving a communication packet through the physical channel.

In the uplink data transmission process, the gateway can package the communication message according to the protocol format and then send the communication message to the server through the physical communication. The communication message may be a communication message of a gateway or a communication message of a sub-device. When packaging, the information of the affiliated resource party can be added in the resource path, wherein the information of the affiliated resource party comprises: gateway information of the gateway and/or device information of the sub-device, for example, the gateway information is added to the communication packet of the gateway, and the sub-device information is added to the communication packet of the sub-device, including information such as device (gateway) name and identifier.

In one example, the child device may send a communication packet to the gateway, and the gateway encapsulates the communication packet according to a protocol and then forwards the encapsulated communication packet through the physical channel. In another example, the gateway encapsulates its own communication packet according to a protocol, and then forwards the encapsulated communication packet through the physical channel.

Then, a resource party of the communication packet may be determined according to the resource path, and the first session or the second session may be selected to forward the communication packet according to the resource party, including the following

steps

804 and 810.

Step 804, acquiring a resource path corresponding to the communication message, and judging whether a resource party is a gateway according to the resource path.

The server acquires the resource path from the encapsulated communication message, and then determines the resource party according to the resource path, namely, whether the resource party is a gateway can be judged. If yes, go to step 806; if not, go to step 808.

Step 806, forwarding the communication packet through the second session.

And if the resource side is the gateway, the server forwards the service platform corresponding to the communication message through the second session.

And 808, judging whether the resource side is the sub-equipment bound with the gateway or not according to the resource path.

If the resource side is not the gateway, whether the resource side in the resource path is the resource device bound by the gateway can be further judged. If the sub-device is judged to have a binding relationship with the physical channel, whether the sub-device is located in the device list of the gateway, and the like. If yes, go to step 810, otherwise go to step 812.

Step 810, forwarding the communication packet through the first session corresponding to the sub-device.

And if the resource side is the sub-equipment bound with the gateway, acquiring a first session corresponding to the sub-equipment, and then forwarding the communication message to a service platform through the first session corresponding to the sub-equipment.

Step 812, discarding the communication packet.

If the resource side is not the sub-device bound with the gateway, the communication message is determined to be the communication message of the illegal device, and the communication message can be discarded.

For example, when the method is executed in MQTT manner, the resource path corresponding to the communication packet sent by the gateway itself is: and (3) mqtttopic/g 1/upload, the server can find the second session s2 according to the gateway g1, so that the communication message is forwarded to the service platform through the second session s 2. Correspondingly, the resource path corresponding to the communication message of the gateway sending sub-device is as follows: and mqtttopic ═ d1/upload, the server can find the first session s1 according to the sub-device d1, and then forward the communication message to the service platform through the first session s 1. Therefore, the communication messages of the gateway and the sub-equipment can be transmitted through the same physical channel and the server, the server can inquire corresponding logic sessions according to the resource paths corresponding to the communication messages to transmit the communication messages, data formats are not invaded in the transmission process of the communication messages, and users can transmit data packets with any format to the service platform.

Referring to fig. 9, a flowchart illustrating a step of downlink transmission in an embodiment of an inter-device communication method according to the present application is shown, which specifically includes the following steps:

step 902, receiving the communication message through a session.

The communication message corresponding to the service platform can be forwarded to the device side through the server, so that the service platform can interface to input target devices such as a gateway, a sub-device and the like when the service platform needs to execute the service, and then the communication message can be sent to the server by adopting the session corresponding to the target device. The session includes a first session and/or a second session. For example, the communication message of the gateway is sent to the server through the second session, and the communication message of the sub-device is sent to the server through the first session.

In one example, one sub-device mounted under the home internet of things gateway is a door lock, after the business system sends an unlocking instruction to the door lock, the business system queries a target lock based on information of the door lock, and then sends the unlocking instruction to the server by adopting a first session of the lock.

Step 904, according to the session query mapping relationship, determining the corresponding resource party.

The server determines a resource party corresponding to the communication message according to the mapping relation inquired by the session, wherein the resource party comprises: a gateway or a kid device. And if the mapping relation is queried based on the second session, determining the corresponding resource party to be the gateway, and if the mapping relation is queried based on the first session, determining the corresponding resource party to be the sub-device.

Step 906, determining the bound physical channel according to the resource side.

The gateway can inquire the physical channel correspondingly bound with the gateway, and the physical channel of the gateway correspondingly bound with the sub-device can also be inquired based on the sub-device.

For example, by sending the communication packet through s2, it may be determined that the communication packet belongs to gateway g1 in g1-s2, and then the physical channel c1 may be determined based on the binding relationship g1-c 1. If the communication packet is sent through s1, it may be determined that the communication packet belongs to the sub-device d1 through d1-s1, and then the physical channel c1 may be determined based on the binding relationship d1-c 1.

Step 908, forwarding the communication packet through the physical channel.

Communication messages may be forwarded to the gateway via the physical channel. After receiving the communication message, the gateway can determine the communication message belonging to the gateway or the sub-device based on the resource side information in the communication message, such as gateway information, device information, and the like, and forward the communication message belonging to the sub-device to the corresponding sub-device. The communication message belonging to the gateway can be processed by itself.
