Detailed Description
Exemplary embodiments of the present invention are described below with reference to the accompanying drawings, in which various details of embodiments of the invention are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
It should be noted that the embodiments of the present invention and the technical features of the embodiments may be combined with each other without conflict.
Fig. 1 is a schematic diagram of main steps of a connection method of a terminal device in an internet of things system according to an embodiment of the present invention.
As shown in fig. 1, when the method for connecting terminal devices in an internet of things system according to an embodiment of the present invention is applied to a scheduling server, the method mainly includes the following steps:
step S101: the method comprises the steps of obtaining a first connection request of a terminal device, wherein the first connection request indicates device information of the terminal device.
The terminal equipment can be intelligent equipment in an internet of things system, such as various intelligent household appliances (intelligent refrigerators, intelligent sound boxes and the like). The first connection request may be a registration message sent by the terminal device, or may be a login message sent by the terminal device after registration, and the terminal device requests the scheduling server to establish a socket connection according to the first connection request. The device information of the terminal device comprises connection information, the capability of the terminal device and authentication-related information, the connection information of the terminal device comprises an IP address, a terminal identification and the like of the terminal device, the capability of the terminal device comprises a connection protocol supported by the terminal device, a supported media type, an encoding type and the like of the terminal device, and the authentication-related information of the terminal device comprises a user name, a password, a certificate and the like of the terminal device.
Step S102: and requesting an authentication server to authenticate the terminal equipment according to the equipment information.
Step S103: and when the authentication server successfully authenticates the terminal equipment, determining at least one service server capable of establishing communication connection with the terminal equipment.
After receiving the first connection request of the terminal device, the scheduling server may send a first authentication request to the authentication server according to the device information of the terminal device, so as to request the authentication server to authenticate the terminal device. The authentication server can authenticate the terminal equipment according to the first authentication request and the equipment information of the terminal equipment. It is understood that, when the first connection request is a registration message, the authentication server may perform registration authentication on the terminal device according to the first authentication request, and when the first connection request is a login message, the authentication server may perform login authentication on the terminal device according to the first authentication request. When the authentication server successfully authenticates the terminal equipment, the authentication server returns an authentication result of successful authentication to the scheduling server, and the scheduling server can establish socket long connection with the terminal equipment according to the authentication result. And the authentication server may store a first credential corresponding to the first authentication request, where the first credential includes scheduling information of the scheduling server and device information, where the scheduling information of the scheduling server includes a time when the scheduling server establishes a socket long connection with the terminal device, a time when the scheduling server notifies the terminal device of the service server, and/or a serial number when the scheduling server notifies the terminal device of the service server.
When the scheduling server receives an authentication result about the first authentication request sent by the authentication server and the authentication result is successful, the scheduling server can determine at least one service server capable of establishing communication connection with the terminal equipment. When determining a service server capable of establishing communication connection with a terminal device, a scheduling server may use at least one service server, of which a ratio of a current flow to a maximum flow is smaller than a preset threshold, as the at least one service server capable of establishing communication connection with the terminal device according to the current flow and the maximum flow of the service server in the internet of things system.
For example, if the service server a can establish communication connections with at most 100 terminal devices at the same time, the maximum traffic of the service server a is 100. And the service server a has currently established communication connections with 80 terminal devices, which indicates that the current flow of the service server a is 80. The ratio of the current traffic of the traffic server a to its maximum traffic is 4/5. If the preset threshold is 1/2, the ratio of the current traffic to the maximum traffic of the service server a at this time is greater than the preset threshold, and then the service server a cannot be used as a service server capable of establishing a communication connection with the terminal device. In addition, if the maximum flow rates of the service server B and the service server C are both 100, and when the current flow rates of the service server B and the service server C are 20, the preset threshold is still 1/2, both the service server B and the service server C can be used as service servers capable of establishing communication connection with the terminal device. Therefore, the service server capable of establishing communication connection with the terminal equipment is determined according to the current flow and the maximum flow of the service server, so that the balance of the whole resources is facilitated, and the connection availability of the terminal equipment and the service server is further improved.
Step S104: and sending a first push message to the terminal equipment to inform the terminal equipment of the at least one service server, so that the terminal equipment selects a target service server from the at least one service server to establish communication connection.
After the scheduling server determines a service server capable of establishing a communication connection with the terminal device (here, taking a service server B and a service server C as an example), a first push message may be sent to the terminal device through the socket long connection, where the first push message may include channel addresses of the service server B and the service server C and versions of connection protocols supported by the channel addresses. The terminal device can then select a target service server from one or more service servers with which a communication connection can be established to establish a communication connection according to the first push message.
It will be appreciated that the capabilities of the terminal device may vary for different types of terminal devices (e.g., both types of smart refrigerator and smart speaker), for example, the connection protocol that it supports may vary. Therefore, the target service servers selected by different types of terminal devices are different, for example, the intelligent refrigerator selects the service server B corresponding to the connection protocol supported by the intelligent refrigerator, and the intelligent loudspeaker selects the service server C corresponding to the connection protocol supported by the intelligent loudspeaker.
Of course, when the scheduling server determines that there is no service server capable of establishing communication connection with the terminal device, the scheduling server may send a prompt message indicating connection failure to the terminal device, so as to avoid that the terminal device cannot successfully connect due to continuously sending a connection request, and improve the availability of the terminal device.
In addition, the scheduling server may manage the operational status of the traffic server. After the terminal device establishes communication connection with the target service server, if the target service server is in an abnormal state due to network quality problems or other problems, the scheduling server can send a second push message to the terminal device to notify the terminal device of the service server in a normal state, so that the terminal device can establish communication connection with the service server in the normal state again according to the second push message, thereby realizing flexible control of a connection channel of the terminal device, and when the target service server is in an abnormal state, the communication between the terminal device and the service server is ensured through a fast switching channel, thereby improving the usability of the terminal device.
According to the connection method of the terminal equipment in the Internet of things system, the dispatching server requests the authentication server to authenticate the terminal equipment according to the first connection request sent by the terminal equipment. The authentication server can authenticate the terminal equipment according to the equipment information indicated by the first connection request, when the authentication is successful, the scheduling server can determine at least one service server capable of establishing communication connection with the terminal equipment, and inform the determined at least one service server to the terminal equipment through the first push message, so that the terminal equipment can select a target service server from the at least one service server for connection. The target service server is the service server which is determined by the scheduling server and can establish communication connection with the terminal equipment, so that the terminal equipment can be ensured to be successfully established with the target service server, the success rate of connection is further improved, the terminal equipment is prevented from being incapable of successfully connecting due to the fact that the terminal equipment continuously sends the connection request, and the availability of the terminal equipment is improved. In addition, the authentication server is used for authenticating the terminal equipment so as to separate the authentication process from the service server, thereby reducing the workload of the service server and being beneficial to improving the success rate of connection.

In an embodiment of the present invention, the authentication interaction module 202 is configured to, according to a current traffic and a maximum traffic of a service server in the internet of things system, use at least one service server, where a ratio of the current traffic to the maximum traffic is smaller than a preset threshold, as the at least one service server capable of establishing a communication connection with the terminal device.
In an embodiment of the present invention, the pushing module 203 is further configured to, when it is determined that there is no at least one service server capable of establishing a communication connection with the terminal device, further include: and sending prompt information representing connection failure to the terminal equipment.
According to the scheduling server in the internet of things system, the scheduling server requests the authentication server to authenticate the terminal equipment according to the first connection request sent by the terminal equipment. The authentication server can authenticate the terminal equipment according to the equipment information indicated by the first connection request, when the authentication is successful, the scheduling server can determine at least one service server capable of establishing communication connection with the terminal equipment, and inform the determined at least one service server to the terminal equipment through the first push message, so that the terminal equipment can select a target service server from the at least one service server for connection. The target service server is the service server which is determined by the scheduling server and can establish communication connection with the terminal equipment, so that the terminal equipment can be ensured to be successfully established with the target service server, the success rate of connection is further improved, the terminal equipment is prevented from being incapable of successfully connecting due to the fact that the terminal equipment continuously sends the connection request, and the availability of the terminal equipment is improved. In addition, the authentication server is used for authenticating the terminal equipment so as to separate the authentication process from the service server, thereby reducing the workload of the service server and being beneficial to improving the success rate of connection.
Fig. 3 is a schematic diagram of main modules of a scheduling server in an internet of things system according to an embodiment of the invention.
As shown in fig. 3, an internet of things system 300 according to an embodiment of the present invention includes: a terminal device 301, an authentication server 302, at least one service server 303, and a scheduling server 304 according to any of the above embodiments; wherein,
the authentication server 302 is configured to receive a first authentication request sent by the scheduling server 304, where the first authentication request indicates device information of the terminal device 301; authenticating the terminal device 301 according to the first authentication request, and when the authentication is successful, returning an authentication result of the successful authentication to the scheduling server 304;
the scheduling server 304 is configured to determine, according to the authentication result, at least one service server capable of establishing a communication connection with the terminal device 301 from the at least one service server 303, and send a first push message to the terminal device 301, so as to notify the terminal device 301 of the determined at least one service server;
the terminal device 301 is configured to select a target service server from the at least one service server determined by the scheduling server 304 according to the first push message to establish a communication connection.
In order to further ensure the connection availability between the terminal device and the target service server, the terminal device may be authenticated in a secondary authentication manner. That is, after the authentication server authenticates the terminal device according to the device information indicated by the first connection request, the authentication server may authenticate the terminal device again when the terminal device establishes a communication connection with the target service server. Specifically, in an embodiment of the present invention, the dispatch server 304 is further configured to push an authentication address of the authentication server to the terminal device 301, so that the terminal device 301 sends a second authentication request to the authentication server 302 according to the identification information, so that the authentication server 302 authenticates the terminal device according to the second authentication request.
In this embodiment, after the dispatch server establishes a socket connection with the terminal device, in addition to notifying the terminal device of the service server that can establish a communication connection with the terminal device through the first push message, the terminal device is also notified of an authentication address of the authentication server, where the authentication address may be a contact address of the authentication server (e.g., an ip address of the authentication server), so that the terminal device can request secondary authentication from the authentication server according to the authentication address. It is to be understood that, when the scheduling server notifies the terminal device of the authentication address of the authentication server, the notification may be performed by the first push message, or may be performed by another push message other than the first push message. That is, the scheduling server may write the authentication address of the authentication server in the first push message, or may notify the terminal device by another push message without writing the first push message.
After receiving the authentication address of the authentication server, the terminal device may send a second authentication request to the authentication server, so as to initiate a second authentication to the authentication server according to the second authentication request. In an embodiment of the present invention, the second authentication process may be implemented as follows:
the authentication server 302 is configured to generate authentication information according to the device information when receiving the second authentication request, and send the authentication information to the service server; when a third authentication request sent by a target service server is received, authenticating the terminal equipment according to the authentication information, and when the authentication is successful, returning an authentication result of successful authentication to the target service server;
the terminal device 301 is configured to send a second connection request to a target service server in at least one service server capable of establishing a communication connection with the terminal device according to the first push message, where the second connection request indicates device information of the terminal;
the target service server is configured to send the third authentication request to the authentication server 302 according to the authentication information corresponding to the second connection request; and establishing communication connection with the terminal equipment 301 according to the authentication result of successful authentication sent by the authentication server 302.
Here, the terminal device may transmit a second authentication request to the authentication server according to the authentication address of the authentication server transmitted by the scheduling server to initiate a second authentication to the authentication server. The authentication server may generate authentication information according to the device information after receiving the second authentication request. When generating the authentication information, the authentication server may generate the authentication information by encrypting the device information, and transmit the authentication information to the service server. When generating the authentication information, the authentication server may also encrypt a first credential corresponding to the first authentication request stored at the time of the first authentication, and generate a second credential, so as to use the second credential as the authentication information. That is, the authentication server may directly encrypt the device information of the terminal device, or may encrypt the schedule information and the device information stored at the time of the first authentication to generate the authentication information.
And after generating the authentication information, the authentication server sends the authentication information to the service server. It can be understood that the authentication server may directly send the authentication information to the target service server, or may broadcast the authentication information to a plurality of service servers in the internet of things system. When the terminal equipment sends the second connection request to the target service server, the target service server sends corresponding authentication information to the authentication server so as to initiate a third authentication request to the authentication server, and the authentication server authenticates the terminal equipment according to the authentication information. After receiving the third authentication request, the authentication server decrypts the authentication information according to the authentication information indicated by the third authentication request to obtain the device information of the terminal device, and then the authentication server can compare the device information obtained by decryption with the pre-stored device information, and when the device information obtained by decryption is the same as the pre-stored device information, it can be determined that the authentication of the terminal device is successful. The device information pre-stored by the authentication server may be the device information of the terminal stored by the authentication server at the time of the first authentication, or the device information indicated when the terminal device sends the second authentication request. Of course, if the authentication information is obtained by encrypting the scheduling information and the device information, the scheduling information and the device information are obtained by decryption, and at this time, both the scheduling information and the device information need to be authenticated to authenticate the terminal device.
After the authentication server carries out secondary authentication on the terminal equipment according to the authentication information, if the authentication is successful, the authentication result which is successfully authenticated is sent to the target service server, then the target service server can establish communication connection with the terminal equipment according to the authentication result sent by the authentication server, and then the terminal equipment can carry out service communication with the target service server. Therefore, the terminal equipment is authenticated for the second time through the authentication server, the connection availability of the terminal equipment and the target service server is ensured through double authentication when the terminal equipment is connected with the scheduling server for the first time and the communication connection is established between the terminal equipment and the target service server for the second time, and the connection availability and reliability are improved. And the authentication server authenticates the terminal equipment to separate the authentication process from the service server, thereby reducing the workload of the service server and being beneficial to improving the success rate of connection.
The following describes in detail a connection method of a terminal device in an internet of things system according to an embodiment of the present invention, taking an example in which an authentication server performs secondary authentication on the terminal device.

Here, the dispatch server may notify the terminal device of the determined authentication addresses of the at least one service server and the authentication server through the first push message at the same time, or may notify the terminal device of the determined authentication addresses of the at least one service server and the authentication server through two push messages, respectively.
Step S405: and the terminal equipment sends a second authentication request to the authentication server according to the authentication address of the authentication server.
Step S406: and the authentication server generates authentication information according to the equipment information indicated by the second authentication request and sends the authentication information to the service server.
Step S407: and the terminal equipment selects a target service server from the at least one service server determined by the scheduling server according to the first push message, and sends a second connection request to the target service server.
The execution sequence of the terminal device sending the second authentication request to the authentication server and sending the second connection request to the target service server may be different, that is, the execution sequence of step S405 and step S407 is different. It is to be noted that step S406 is always performed after step S405.
Step S408: and when receiving the second connection request, the target service server sends a third authentication request to the authentication server, wherein the third authentication request indicates the authentication information.
Step S409: and the authentication server authenticates the terminal equipment according to the third authentication request and the authentication information, and sends an authentication result of successful authentication to the target service server when the authentication is successful.
Step S410: and the target service server establishes communication connection with the terminal equipment according to the authentication result.
According to the Internet of things system provided by the embodiment of the invention, the following can be seen: and the scheduling server requests the authentication server to authenticate the terminal equipment according to the first connection request sent by the terminal equipment. The authentication server can authenticate the terminal equipment according to the equipment information indicated by the first connection request, when the authentication is successful, the scheduling server can determine at least one service server capable of establishing communication connection with the terminal equipment, and inform the determined at least one service server to the terminal equipment through the first push message, so that the terminal equipment can select a target service server from the at least one service server for connection. The target service server is the service server which is determined by the scheduling server and can establish communication connection with the terminal equipment, so that the terminal equipment can be ensured to be successfully established with the target service server, the success rate of connection is further improved, the terminal equipment is prevented from being incapable of successfully connecting due to the fact that the terminal equipment continuously sends the connection request, and the availability of the terminal equipment is improved.
