Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without inventive step, are within the scope of the present application.
Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
An execution main body of the information intercommunication method may be the information intercommunication device provided in the embodiment of the present application, or an electronic device integrated with the information intercommunication device, where the information intercommunication device may be implemented in a hardware or software manner. The electronic device may be a smart phone, a tablet computer, a palm computer, a notebook computer, or a desktop computer.
Referring to fig. 1, fig. 1 is a first flowchart illustrating an information interworking method according to an embodiment of the present application. The specific process of the information intercommunication method provided by the embodiment of the application can be as follows:
in 101, after establishing a network connection with a network access device, a TCP connection is initiated to the network access device through a preset port.
In 102, if the TCP connection is successfully established, a first interworking request is sent to the network access device according to an interworking protocol.
The scheme of the embodiment of the application provides an information intercommunication protocol, and the information intercommunication protocol is used for information intercommunication between electronic equipment and network access equipment. The network access device may be a device capable of providing a wireless network access service, such as a router, a wireless CPE (Customer Premise Equipment), or a device capable of providing a wired network access service. The following describes a scheme of an embodiment of the present application, taking a network access device as a router and a network connection as a WIFI (Wireless Fidelity) connection as an example.
Since the communication between the electronic device and the router is a local area network communication, the information interworking protocol may be designed based on a C/S (server/client) architecture, where the electronic device is a client and the router is a server. In addition, because the data transmitted between the two devices is generally signaling data, and the requirement on the reliability of data transmission is high, the TCP socket mode can be adopted for communication. The information intercommunication protocol specifies a specific port number of the router to establish TCP connection, and after the TCP connection is successfully established, information intercommunication is carried out according to a preset message format.
For example, the message may adopt a Json (JS Object Notation) format, for example, the format specification of the message is as follows:
1. request message:
{"version":"1.0","method":"get","data":["data1","data2"]}
{"version":"1.0","method":"notify","data":{"data1":"XXX","data2":"XXX"}}
2. replying the message:
{"version":"1.0","method":"reply","error_code":"0","error_msg":"XXX","data":{"data1":"XXX","data2":"XXX"}}
{"version":"1.0","method":"ack","error_code":"0","error_msg":"XXX"}
3. the basic rule is as follows:
1) a primary directory comprising: version, method, error _ code, error _ msg, data. Wherein, version is a protocol version number, method is a message type, error _ code is an abnormal code, error _ msg is abnormal content, and data is data content.
2) method, including the 4 keywords get, notify, reply, ack; get corresponds to reply and notify corresponds to ack. Wherein get indicates that the message type is a request message, reply indicates that the message type is a reply message, notify indicates that the message type is a notification message, and ack indicates that the message type is a response message.
3) When the data is get, the data is an array, and each keyword in the array represents that the data expects to acquire information.
4) When the data gets, an ap _ all _ info is used to represent that all information of an ap (access point) end is obtained. For example, ap is a router.
5) When the data is at get, all information of the electronic equipment side is acquired by using a "sta _ all _ info" mark.
6) data is a child Json in notify/reply.
7) An error _ code is an exception definition after a message processed by a reply end to a sending end, and the default value is 0, which indicates no exception;
8) the error _ msg is a description of a recovery end error _ code and is mainly used for debug (troubleshooting); when error _ code is 0, error _ msg may not be carried in the message.
The traditional TCP only supports single-path transmission, and the introduction of a multi-path transmission mechanism realizes the simultaneous utilization and sharing of multi-host resources on the premise of not changing the basic architecture of the TCP. The principle of MPTCP is that in a resource sharing manner, a data stream can be distributed to multiple parallel paths for simultaneous transmission, so as to improve the bandwidth of a network. That is, the multipath communication protocol allows multiple links to be established between two communicating parties simultaneously for data transmission, and there are multiple ways to select a link when data transmission is performed using the multiple links.
The link in MPTCP may be established through a WIFI network or a cellular network, and the network access device may be a router, a base station, or other devices capable of providing network access services. For example, in one embodiment, the two communication parties are an electronic device and a router, and the MPTCP connection here mainly refers to an MPTCP connection between the electronic device and an router, and the MPTCP connection is composed of a plurality of TCP connections. The MPTCP connection may have a plurality of data transmission modes, such as an aggregation transmission mode, a redundancy transmission mode, and a backup transmission mode.
In the aggregation transmission mode, at least two links are used for transmitting a plurality of data packets of a message at the same time, one data packet is transmitted only through one link, and at least two links transmit different data packets. After the data stream transmitted by the upper layer application is split into a plurality of data packets, different data packets can be simultaneously transmitted through two links. The aggregation transmission mode can save network resources, furthest utilize broadband resources to improve data transmission efficiency, and is suitable for application programs with large data flow or high requirements on data real-time performance. If the data sent by the electronic device and received by the router is the multi-link aggregation transmission, the data transmitted to the electronic device is also transmitted in a multi-link aggregation transmission mode.
In the redundant transmission mode, two links are used simultaneously to transmit the same data packet. That is, one data packet is repeatedly transmitted through a plurality of links, and this transmission mode can ensure the reliability of data and reduce the burden of the receiving end. However, the transmission mode requires that the gateways of the two connected WIFI hotspots are the same, and the router side performs deduplication processing on at least two paths of received data and then sends the data to the server. And after receiving the data sent by the server, the router also needs to transmit the data to the electronic device according to the redundancy mode, and after receiving the data, the electronic device also needs to perform deduplication processing on the received data packet and then sends the data packet to the upper layer application.
In the standby transmission mode, although two or more links are established, only one link is generally selected for transmitting data packets, but when the currently used link is detected to be out of service requirements, the other link is switched to transmit data packets. After the new link is switched, if the data packet of the application program is received again next time, the switched link can be used for data transmission.
In the three transmission modes, the processing requirements of the electronic device on data are different, and therefore, the electronic device can set one or more supportable transmission modes according to needs.
If the electronic equipment selects to transmit data according to a certain network connection mode, information can be communicated with the connected router before data transmission to determine whether the other party supports the network connection mode, so that a transmission mode with higher efficiency or higher reliability is selected to transmit the data.
For example, if the electronic device supports dual WIFI functionality, the electronic device may establish an MPTCP connection with a router that supports MPTCP connections. For example, the electronic device may establish two links with two WIFI hotspots at the same time, assuming that one 2.4GHz hotspot and one 5GHz hotspot have no interference between different frequency bands, and may concurrently and independently receive and transmit data, where the two hotspots may be of the same router (e.g., a home dual-frequency router) or of different routers. When two hotspots belong to the same router, redundant transmission of data can be performed between the electronic device and the router.
The capability information of the device represents a network connection mode supported by the device, the capability information of the router is recorded as first capability information, and the capability information of the electronic device is recorded as second capability information. For example, the first capability information is: the MPTCP connection indicates that the electronic device supports the MPTCP connection. For another example, the first capability information is: the aggregate transmission mode of the MPTCP connection indicates that the electronic device supports the MPTCP connection, but can only transmit data according to the aggregate transmission mode.
Referring to fig. 2, fig. 2 is a scene diagram illustrating an information interworking method according to an embodiment of the present application. After the electronic device establishes the WIFI connection with the router, for example, after a DHCP (Dynamic Host Configuration Protocol) process is finished, the electronic device initiates a TCP connection to the router through a preset port, where the preset port is a port specified by an information interworking Protocol.
If the TCP connection is successfully established, the subsequent information intercommunication is continued, and a first information intercommunication request is initiated to the router according to the message format specified by the information intercommunication protocol. If the TCP connection establishment fails, the electronic device may determine that the router does not support the interworking protocol. Subsequent information interworking is not performed.
In 103, first capability information sent by the network access device in response to the first information interworking request is received, where the first capability information characterizes a network connection mode supported by the network access device.
At 104, when a second information interworking request sent by the network access device according to the information interworking protocol is received, second capability information is sent to the network access device in response to the second information interworking request, where the second capability information represents a network connection mode supported by the electronic device.
Referring to fig. 2, after receiving the first information interworking request, the router responds to the capability information requested by the electronic device according to the message format specified by the information interworking protocol. Then, the router sends a second information intercommunication request to the electronic equipment according to the message format specified by the information intercommunication protocol, and the electronic equipment responds to the capability information requested by the router after receiving the request.
Wherein, in some embodiments, the network connection mode is an MPTCP connection; after establishing WIFI connection with the router, initiating TCP connection to the router through a preset port, including: after the WIFI connection with the first access point of the router is established, TCP connection is initiated to the router through the preset port.
After the sending the second capability information to the network access device, the method further includes:
if the network connection mode supported by the electronic equipment and the wireless network access equipment is determined to be a multi-path transmission control protocol (MPTCP) connection according to the first capability information and the second capability information, triggering the MPTCP connection with the network access equipment when detecting that the network connection is established with at least one second access point of the network access equipment, and transmitting data based on the MPTCP connection.
For a router with at least two access points (hotspots), after the electronic device establishes a WIFI connection with a first access point of the router, capability intercommunication is performed according to the above information intercommunication protocol to confirm a commonly supported network connection mode. For example, the first capability information is: the MPTCP connection is connected to the MPUDP (multi path User Datagram Protocol), and the second capability information is: MPTCP connection. It can be determined that the network connection mode commonly supported by the electronic device and the router is an MPTCP connection. For another example, in some embodiments, the first capability information is: the second capability information of the redundant transmission mode of the MPTCP connection is: redundant transmission mode of MPTCP connection. It can thus be determined that both the electronic device and the router support an MPTCP connection and that the transmission of data can be performed in accordance with the redundant transmission mode of the MPTCP connection.
After that, if the electronic device detects that the WIFI connection is also established with the at least one second access point of the router, the electronic device may send notification information to the router based on the information interworking protocol, where the notification information is used to notify the router that the WIFI connection is established next time. Then, an MPTCP connection between the router and the MPTCP is triggered, and data transmission is carried out based on the MPTCP connection.
For a router capable of providing multiple WIFI hotspots simultaneously, one of the WIFI hotspots can be regarded as a main WIFI and recorded as a first access point, and the other WIFI hotspots can be regarded as a secondary WIFI and recorded as a second access point. For example, the router may provide two access points, the frequency bands of which are 2.4GHz and 5GHz, respectively, and the two frequency bands do not interfere with each other and transmit data together. MPTCP connection is established between the electronic equipment and the router based on two hot spots, and data redundant transmission is carried out according to a redundant transmission mode. Or in other embodiments, when it is detected that the device accesses the WIFI network, the electronic device may further use the first connected WIFI hotspot as the first access point, and use the second connected WIFI hotspot as the second access point.
In some embodiments, after the sending the first information interworking request to the network access device according to the information interworking protocol between the electronic device and the network access device, the method further includes: and if the network access equipment does not respond to the first information intercommunication request within a preset time length, releasing the TCP connection.
It can be understood that if the network access device does not receive the response information returned by the router within 3 seconds in the preset market after initiating the first information interworking request, it is determined that the router does not support the information interworking protocol, and the TCP connection can be actively released.
Wherein, in some embodiments, the method further comprises: and when the disconnection of the WIFI connection is detected, emptying the stored first capability information of the network access equipment.
In this embodiment, after the WIFI connection is disconnected, the electronic device clears the stored capability information of the router, and performs information intercommunication again when the router is connected next time. Therefore, the problem that the matching of the capability information is wrong due to the fact that the SSIDs (Service Set identifiers) of the hot spots are the same can be avoided.
In addition, in some embodiments, if the TCP connection is successfully established, sending a first information interworking request to the network access device according to an information interworking protocol includes:
if the TCP connection is successfully established, a secret key is sent to the network access equipment according to the information intercommunication protocol;
when first message data sent by the network access equipment is received and the key is used for decrypting the first message data to obtain response information, the key is used for encrypting a first information intercommunication request to obtain second message data;
and sending the second message data to the network access equipment, wherein the network access equipment decrypts the second message data by using the secret key to obtain a first information intercommunication request. .
In this embodiment, to improve the security of message transmission, the message between the electronic device and the router is encrypted according to the agreed key.
For example, the electronic device and the network access device encrypt the message in a symmetric encryption manner. Specifically, after the electronic device and the network access device successfully establish the TCP, an AES (Advanced Encryption Standard) key is generated, the key is sent to the router according to a message format specified by an information interworking protocol, the router receives the key and stores the key, and the router sends first message data to the electronic device, where the first message data includes response information encrypted by using the key.
After the electronic equipment receives the first message data, if response information is obtained after information in the first message data is decrypted according to the secret key, a first information intercommunication request is generated, the secret key is used for carrying out encryption processing on the first information intercommunication request, second message data is generated, and the second message data is sent to the network access equipment. And after receiving the second message data, the network access equipment decrypts the second message data according to the stored secret key to obtain the first information intercommunication request.
It can be understood that, in the above process, the router and the electronic device respectively send the first message data and the second message data according to the message format specified by the information interworking protocol.
For another example, in an embodiment, the sending the key to the network access device according to the information interworking protocol includes:
requesting a public key from the network access equipment according to the information intercommunication protocol, wherein the network access equipment generates a key pair comprising the public key and a private key after establishing the TCP connection;
when a public key returned by the network access equipment according to the information intercommunication protocol is received, the public key is used for carrying out encryption processing on the secret key to obtain third message data;
and sending the third message data to the network access equipment, wherein the network access equipment decrypts the received first message data according to the private key to obtain the first secret key.
After the electronic device and the network access device successfully establish the TCP, the electronic device generates an AES key, the router generates an RSA (an asymmetric encryption algorithm) key pair, the key pair comprises a public key and a private key, wherein the public key is sent to the electronic device to be used for encrypting the AES key generated by the electronic device, and the private key is used for decrypting information encrypted by the public key.
Then, the electronic equipment requests the router for the RSA public key, the router returns the RSA public key, the electronic equipment encrypts the AES secret key through the RSA public key to obtain third message data, and the third message data are sent to the router according to a message format specified by the information intercommunication protocol. The router decrypts the third message data by using the RSA private key to obtain an AES key, then sends response information to the electronic equipment, and after receiving the response information, the electronic equipment encrypts the first information intercommunication request by using the key and then sends the first information intercommunication request to the network access equipment.
It can be understood that, in the above process, the electronic devices respectively transmit the third message data according to the message format specified by the information interworking protocol.
In particular implementation, the present application is not limited by the execution sequence of the described steps, and some steps may be performed in other sequences or simultaneously without conflict.
As can be seen from the above, in the information interworking method provided in the embodiment of the present application, an information interworking scheme based on an information interworking protocol between the electronic device and the router is provided, and if both the electronic device and the router support the protocol, the electronic device and the network access device can mutually confirm a network connection mode supported by an opposite terminal before establishing a network in this way, and subsequently, when transmitting data, the network connection mode supported together can be selected to establish a corresponding network connection and perform data transmission.
In addition, an information interworking method is further provided in an embodiment of the present application, and is applied to a network access device, where the method includes:
establishing a TCP connection with the electronic equipment based on a preset port;
when a first information intercommunication request sent by the electronic equipment based on an information intercommunication protocol is received, responding to the first information intercommunication request, and sending first capability information to the electronic equipment, wherein the first capability information represents a network connection mode supported by the network access equipment;
sending a second information intercommunication request to the electronic equipment according to the information intercommunication protocol;
and receiving second capability information sent by the electronic equipment in response to the second information interworking request, wherein the second capability information represents a network connection mode supported by the electronic equipment.
