A method and system for achieving rapid device interconnection

Abstract

This invention discloses a method and system for achieving rapid device interconnection. The invention involves a first terminal and a second terminal acquiring their own IP and port information, broadcasting this information via the CoAP protocol, and continuously monitoring surrounding broadcast information. Upon detecting the first terminal's broadcast information, the second terminal establishes a session connection with the first terminal based on the IP and port information in the broadcast. The second terminal receives an application service request and sends an interconnection request along with its own terminal information to the first terminal based on the application service request. The first terminal receives the interconnection request and, after successful authentication via the identity authentication mechanism, selects an interconnection channel based on its terminal information to establish an interconnection with the second terminal. This invention achieves device interconnection more quickly and conveniently. Furthermore, because it can automatically select an interconnection channel, it avoids the need for developers to deal with heterogeneous networks, reducing development costs and offering better scalability.

[0101] The method and the terminal for realizing fast interconnection of devices are suitable for a scenario in which two terminals need to be interconnected.

[0102] Please refer to Figure 1 , Figure 3 and Figure 4 , the first embodiment of the present application is:

[0103] A method for realizing fast interconnection of devices, comprising the steps of:

[0104] S1, a first terminal and a second terminal respectively acquire IP and port information of themselves, broadcast the IP and port information through a CoAP protocol, and continuously listen to surrounding broadcast information;

[0105] In this embodiment, please refer to Figure 4 , the relevant program resources in the terminal are divided into a user application layer, a self-organizing network adaptation layer and a system layer. The user application layer is a user of device discovery and interconnection function, decides when to call an interface to acquire a device list or establish device interconnection with a target terminal according to the business requirement of the application itself; the system layer is a module for realizing device system function, executes a corresponding connection request after the self-organizing network adaptation layer completes connection mode decision and connection initiation; the self-organizing network adaptation layer provides interfaces for discovering devices and establishing device connection, and provides a developer with a fast and convenient access to device interconnection; and completes main functions such as terminal discovery, connection networking and optimal connection mode decision. The main content of the scheme is realized by the self-organizing network adaptation layer, i.e., a self-organizing network service.

[0106] In this embodiment, the ad hoc network service of the first terminal and the second terminal is started by the user application binding service, or is started when the system is powered on, the IP and port information of the ad hoc network service is read, and the ad hoc network service broadcasts through the CoAP (Constrained Application Protocol, a web-like protocol in the Internet of Things world) service. At the same time, the ad hoc network service starts to listen to the broadcast information of other terminals around, that is, to discover the surrounding devices.

[0107] If the first terminal is a Harmony terminal, the steps S1 and S2 further include the following steps:

[0108] S11, the first terminal creates a session server of the CoAP protocol.

[0109] In this embodiment, the first terminal is a Harmony terminal, and broadcasts the IP and port information while acting as a session server of the CoAP protocol.

[0110] S2, after the second terminal listens to the broadcast information of the first terminal, the second terminal establishes a session connection with the first terminal according to the IP and port information in the broadcast information.

[0111] The step S2 of establishing a session connection with the first terminal according to the IP and port in the broadcast information is specifically:

[0112] The second terminal establishes a session connection with the session server of the first terminal created by the first terminal as a client.

[0113] In this embodiment, after the second terminal listens to the IP and port information sent by the first terminal, the second terminal establishes a connection with the session server of the first terminal as a client through the IP and port information, and obtains the terminal information of the first terminal.

[0114] S3, the second terminal receives an application service request, and sends an interconnection request and terminal information of the second terminal to the first terminal according to the application service request.

[0115] In this embodiment, the device interconnection interface of the ad hoc network service is called by the application of the user on the second terminal according to the needs, an interconnection channel is selected according to the terminal information of the first terminal, and an interconnection request is initiated to the first terminal.

[0116] S4, the first terminal receives the interconnection request, and establishes interconnection with the second terminal according to the terminal information to select an interconnection channel after the identity authentication mechanism is authenticated.

[0117] If the first terminal is a HongMeng terminal, the terminal information includes user account system information and user login information, and the step S4 specifically includes the following steps:

[0118] S41, the first terminal receives the interconnection request, judges whether the user account information and the login user information of the second terminal are consistent with itself, if yes, establishes interconnection with the second terminal, otherwise generates a PIN code and displays it;

[0119] S42, the second terminal initiates the interconnection request again according to the PIN code input by the user;

[0120] S43, the first terminal checks the PIN code in the interconnection request with the PIN code generated by itself, if the check is passed, selects an interconnection channel to establish interconnection with the second terminal;

[0121] In the embodiment, after the second terminal sends the interconnection request to the first terminal, the first terminal needs to be authenticated. The first terminal decides whether to establish interconnection with the second terminal according to the identity authentication mechanism of the HongMeng system. Specifically, if the account systems of the first terminal and the second terminal are the same, and the login account information is consistent, the HongMeng system considers that the first terminal and the second terminal belong to the terminals of the same user, does not pop up a connection prompt, allows the second terminal to establish interconnection with the first terminal, and establishes interconnection with the first terminal according to the terminal information of the second terminal. If the account systems of the first terminal and the second terminal are different, the first terminal generates a PIN code, the second terminal inputs the PIN code, and transmits it back to the first terminal, and the first terminal checks it, and only after the check is passed, the first terminal selects a suitable channel to establish interconnection with the second terminal.

[0122] Please refer to Figure 1 and Figure 3 , embodiment two of the present application is:

[0123] A method for realizing fast interconnection of devices, which is different from embodiment one in that the first terminal is an Android terminal, and the step S11 is specifically:

[0124] S11, the first terminal creates a TCP Socket server session server.

[0125] In the embodiment, after the first terminal broadcasts its IP and port information, the ad hoc service creates a TcpSocket session server and waits to be discovered and connected.

[0126] The step S2 of establishing a session connection with the first terminal according to the IP and port in the broadcast information is specifically:

[0127] The second terminal establishes a session connection with a TCP protocol session server created by the first terminal as a client.

[0128] In this embodiment, after the second terminal listens to the broadcast of the first terminal and discovers the first terminal, the second terminal establishes a session connection with a TCP Socketserver session server created by the first terminal as a client.

[0129] The step S4 specifically includes:

[0130] The first terminal receives the interconnection request, checks the user account system information, the user login information and the owner information of the second terminal, and if the user account system information and the user login information are consistent with itself or the owner information is consistent with itself, the first terminal establishes interconnection with the second terminal, otherwise, the first terminal displays a connection authorization prompt, and after the user confirms the consent, the first terminal selects an interconnection channel according to the terminal information and establishes interconnection with the second terminal.

[0131] In this embodiment, after the first terminal receives the interconnection request and the terminal information of the second terminal, the first terminal needs to be authenticated:

[0132] If the login accounts of the second terminal and the first terminal are consistent, the connection is allowed to be established, and the first terminal does not need to pop up a connection authorization prompt;

[0133] If the owner information of the second terminal and the first terminal is consistent, the connection is allowed to be established, and the first terminal does not need to pop up a connection authorization prompt;

[0134] If the login accounts and the owner information of the second terminal and the first terminal are inconsistent, but the connection has been established, the connection is allowed to be established, and the first terminal pops up a connection authorization prompt;

[0135] If the second terminal and the first terminal belong to stranger devices and have not been connected, the first terminal pops up a connection authorization prompt, and the user clicks to agree to allow the connection to be established.

[0136] The terminal information includes current Wi-Fi information, Bluetooth information, USB port information and NFC information of the terminal;

[0137] In the step S4, the interconnection channel is selected according to the terminal information, specifically including:

[0138] According to a preset priority sequence and the current Wi-Fi information, Bluetooth information, USB port information, Ethernet information and NFC information of the first terminal, the optimal interconnection channel is selected from the available interconnection channels;

[0139] The priority sequence is:

[0140] USB communication > Bluetooth networking > Wi-Fi P2P networking > Wi-Fi AP networking > NFC networking.

[0141] In this embodiment, the first terminal decides the optimal connection channel according to the terminal information sent by the second terminal, including Wi-Fi information, Bluetooth information, USB port information, Ethernet information and NFC information. The networking mode is selected according to the available networking mode between the current second terminal and the first terminal, and the priority is: USB communication > Bluetooth networking > Wi-Fi P2P networking > Wi-Fi AP networking > NFC networking. When the selected interconnection mode cannot complete the interconnection, i.e., the used networking mode is unreachable, the terminal information of the second terminal is reacquired, and the optimal connection channel is redecided.

[0142] After the first terminal and the second terminal successfully establish the device interconnection channel through networking, the required service interaction data can be transmitted through the established interconnection channel.

[0143] Preferably, the terminal data is further provided with a security level, including an encryption type, a specific type and a general type, and the terminal information includes owner information, device ID or login user information.

[0144] When data transmission is performed after the interconnection is established in step S4, the method further includes the following steps:

[0145] S51, the data sender judges the security level of the data to be transmitted, if the data to be transmitted is of the encryption type, steps S52 and S53 are performed, if the data to be transmitted is of the specific type, step S54 is performed, and if the data to be transmitted is of the general type, the transmission is directly performed;

[0146] S52, the data sender generates and displays an identification code, the data receiver communicates with the data sender according to the identification code input by the user and the PAKE protocol, and generates a session key based on a preset algorithm;

[0147] S53, the data sender transmits the data to be transmitted by encrypting the data to be transmitted through the session key;

[0148] S54, the data sender compares and verifies the IP, owner information, device ID or login user information of the data receiver with the data in the preset transmissible list, and transmits the data to be transmitted after the verification is passed.

[0149] In this embodiment, the security level of data is set in advance, and when the user performs data transmission, the data security level can be transmitted when calling the data transmission interface of the unified network interface. In this scheme, the data security level is divided into three types: encrypted data type, which needs to be encrypted during transmission; general data, which directly transmits data; and special data type, which needs to be authenticated by IP and device during transmission.

[0150] For encrypted data, a PIN code is generated by the first terminal, and after the PIN code is input by the second terminal, the first terminal and the second terminal perform handshake based on the PIN code and the PAKE protocol to negotiate a session key, and the encrypted data is transmitted by the key.

[0151] For special type data, such as IP authentication, device authentication, or both. For IP authentication, the first terminal is specified by the user application to be transmitted, and the IP of the second terminal is checked when the second terminal initiates a data transmission request. Device authentication can be authenticated by the user application through terminal owner information or specified terminal information authentication (such as specifying device ID, specifying login user, etc.).

[0152] For data that does not need to be encrypted, it can be transmitted directly after the interconnection channel is established.

[0153] Please refer to Figure 2 , the third embodiment of the present application is:
