[ detailed description ] of the application

For a better understanding of the technical solutions of the present specification, the following detailed description of the embodiments of the present application refers to the accompanying drawings.

It should be understood that the described embodiments are only some, but not all, of the embodiments of the present description. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present disclosure.

The terminology used in the embodiments of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the description. As used in this application and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

In the prior art, the data transmission depends on the appointed server connected by the two transmission parties according to the same established connection information, so as to establish a data transmission channel for data transmission.

Based on the above problems, the embodiment of the application provides a data transmission method, when data transmission is performed between terminals, an APDU link is directly established, point-to-point transmission operation instructions between devices are transmitted, a server is not required to be connected to establish the link, no dependence is caused on the server, and the transmission flexibility is high.

Fig. 1 is a schematic diagram of an implementation environment of a data transmission method according to an embodiment of the present application, and as shown in fig. 1, the implementation environment includes a local electronic device 101 and an opposite electronic device 102. The local end electronic device 101 and the counterpart end electronic device 102 may be any terminal device that can be connected to a network for transmission, such as a personal computer, tablet, smart mobile terminal, personal digital assistant, audio and video player, camera, game console, tablet, smart device, wearable device, vehicle, electricity meter, air pump, large or small kitchen appliance, health care device, implant, display, or any other similar functional device.

Fig. 2 is a flowchart of a data transmission method according to a first embodiment of the present application, where the method is applied to the local side electronic device 101 shown in fig. 1, and as shown in fig. 2, the data transmission method may include:

step 201, obtaining locally stored identity information, wherein the identity information comprises local end identity information and opposite end identity information.

And acquiring all or part of identity information stored in the local storage system, wherein the identity information comprises the identity information of the local electronic equipment and the identity information of the opposite-end electronic equipment. The identity information may include: IMSI (International Mobile Subscriber Identity international mobile subscriber identity), temporary mobile subscriber identity (TMSI, temporary Mobile Subscriber Identity), ACCID user account identification, international mobile equipment identity (International Mobile Equipment Identity, IMEI), number, etc.

Preferably, the key information is obtained in addition to the identity information, where the key information includes a public key and a private key of the local electronic device and a public key of the opposite electronic device.

Step 202, an APDU link establishment request is sent to the peer electronic device, where the request carries the local end identity information.

And packaging the acquired local terminal identity information in a request instruction, wherein the request instruction adopts an APDU format and is used for establishing an APDU link to the opposite terminal electronic equipment.

APDU, application Protocol data unit, application protocol data unit, the instruction being defined by the ISO816 specification of the ISO international organization for standardization/IEC international electrotechnical commission. APDUs can be divided into commands APDU (command APDU) and responses APDU (response APDU). The command APDU contains an optional 4 byte header (CLA, INS, P1, P2) and data segments (0 to 255 bytes of data). In the command APDU, the field INS is used to represent a specific command, such as "authentication", "write data", etc. The INS field defining the command APDU is used to represent different instructions, and the definition needs to be performed with reference to the basic protocols such as GSM11.11 and GSM11.14, and for example, the request instruction in the embodiment of the present application needs to use the command APDU format, the present application does not limit the name of the INS field of the instruction, and may be any name such as Q, and the local side identity information is placed in the data segment of the instruction.

Preferably, the local terminal identity information is encrypted by using the public key of the opposite terminal electronic equipment and then encapsulated in the request instruction in the APDU format.

It is noted that the transmission and reception of the APDU related instructions in the present application are transmitted using a Point-to-Point Protocol (PPP), which is a data link layer (ISO layer 2) communication Protocol used directly between two routes in a computer network, without any host or any other network in between. It may provide connection authentication, transport encryption, and data compression. The point-to-point protocol is specified in the RFC 1661 protocol of the internet engineering task force (Internet Engineering Task Force). PPP has a variety of protocols in its implementation, and the RFC 2516 protocol describes PPPoE (Ethernet point-to-point protocol) as a method of implementing PPP over Ethernet, sometimes used with DSL. The RFC 2364 protocol specifies the point-to-point protocol over ATM (PPPoA), which describes the method of transmitting PPP over ATM adaptation layer 5 (AAL 5), which is also a common alternative to PPPoE used with DSL.

And 203, receiving a request response message sent by the opposite-end electronic equipment.

And receiving a request response message returned by the opposite-end electronic equipment, wherein the format of the request response message is response APDU. The request response message is returned by the opposite-end electronic device for the APDU request instruction sent by the local-end electronic device, specifically, after the opposite-end electronic device receives the instruction sent by the local-end electronic device, the opposite-end electronic device reads the local-end identity information in the data segment, verifies whether the read information is true, and returns the request response message to the local-end electronic device when the read information is true.

It should be noted that the request response message is sent using the same PPP (point-to-point) protocol as the local end electronic device.

Step 204, verifying the opposite terminal information carried in the request response message according to the locally stored opposite terminal identity information;

and the request response message is in response APDU format, the instruction carries the identity information of the opposite terminal, the identity information is read, and whether the information is identical with the opposite terminal identity information stored in the local storage system is verified.

Preferably, when the opposite-end information in the request response message is in an encrypted state, the local-end electronic device private key read in step 201 is used to decrypt the information for verification.

And step 205, when the opposite terminal information passes the verification, establishing an application data unit (APDU) link with the opposite terminal electronic equipment.

When the identity information of the opposite terminal carried in the request response message is the same as the locally stored opposite terminal identity information, the identity of the opposite terminal electronic equipment is successfully confirmed, and an APDU link can be established with the opposite terminal electronic equipment at the moment.

The APDU link refers to a point-to-point protocol connection between the local electronic device and the opposite electronic device, and because all the APDU commands transmitted on the connection in the embodiment of the present application are APDU commands, for convenience of explanation, the APDU commands are called APDU links, and have the advantages of high data transmission efficiency, strong confidentiality, etc.

In steps 201 to 204, the local electronic device has completed a typical request/response mode, i.e. issues a request and receives a response, and the completion of the mode indicates that the local electronic device completes a communication with the opposite electronic device. When the peer electronic device successfully receives the request sent by the local electronic device, it indicates that the local electronic device delivers the request information to a socket (socket), where the socket includes a point-to-point protocol number, an IP address of the local electronic device, a port number used by the local electronic device, a destination IP address, and a destination port number, and then the peer electronic device sends response information to the local electronic device according to the socket, so that the local electronic device completes a PPP protocol communication/connection process with the peer electronic device once.

However, in the embodiment of the present application, although the opposite-end electronic device receives the request response message, the embodiment does not consider that the establishment of a PPP protocol connection for the opposite-end electronic device is completely completed, but considers that a complete communication process is completed after the identity information of the opposite-end electronic device in the request response message is successfully verified. The application, when successfully verifying the opposite terminal electronic equipment identity information in the request response message, shows that the local terminal electronic equipment thoroughly completes the PPP protocol communication process with the opposite terminal electronic equipment once, and successfully establishes a PPP protocol link between the local terminal electronic equipment and the opposite terminal electronic equipment.

Further, after the identity information of the opposite-end electronic device in the request response message is successfully verified, the communication can be further solidified into SendAPDU, recieveAPDU two special function interfaces by means of an auxiliary module such as a net module or a modem module according to the socket so as to be called later.

In some cases, after the APDU link is successful, the local end electronic device needs to establish a monitoring mechanism to monitor the link, where the monitored object includes not only the instruction or data sent by the opposite end electronic device, but also the instruction or data that needs to be sent by the local end, so as to perform a corresponding execution action.

And step 206, sending an operation instruction to the opposite-end electronic equipment through the APDU link, wherein the operation instruction is used for indicating the opposite-end electronic equipment to operate.

After the local terminal electronic device establishes the APDU link through the steps, sending an operation instruction to the opposite terminal electronic device through the link, wherein the operation instruction is also in a format for commanding the APDU, the operation instruction can be used for indicating the opposite terminal electronic device to perform various operations such as data acquisition, when the operation instruction is used for data acquisition, the operation instruction can be identified by an instruction name in an INS field, and the operation instruction can be arbitrary such as G, and can store information for indicating the opposite terminal electronic device to acquire data to be transmitted, such as an IP address and the like for storing the data to be transmitted in a data segment of the instruction.

The benefits of point-to-point connections are obvious, but there are also certain disadvantages to using only point-to-point connections, such as the delay between devices is still significant despite the use of APDU commands, and the transmission experience of large files by point-to-point protocols and APDU commands is poor, etc.

Fig. 3 is a flowchart of a preferred implementation manner of the first embodiment of the present application, where an implementation environment in this embodiment is shown in fig. 4, fig. 4 illustrates an implementation environment of the preferred embodiment of the first embodiment of the present application, as shown in fig. 4, where the implementation environment includes a local electronic device 101, an opposite electronic device 102, and multiple shared servers, where the shared servers may be independent physical servers, a server cluster or a distributed system formed by multiple physical servers, or two independent parts deployed in the same server cluster or independent parts deployed in the same server, such as a middleware service, cloud computing, and each of the shared servers is provided with corresponding configuration information.

As shown in fig. 3, in the embodiment of fig. 2 of the present application, the steps may further include:

step 301, obtaining first configuration information, where the first configuration information corresponds to a first shared server.

In the data transmission system of this embodiment, each shared server is provided with its own corresponding configuration information, where the configuration information is used to connect to the shared server, and the configuration information may be an APN/PDN, which is also referred to as an access point, access Point Name, which determines which access mode is used to access the network, such as a service class of GPRS, where the APN may be regarded as an identifier for an external PDN (Public Data Network ), and the configuration information may also be a domain name, an IP address, or the like in some cases.

The local side electronic equipment acquires first configuration information, wherein the first configuration information is the configuration information for connecting with a first sharing server.

The first configuration information may be stored locally or stored on a remote server, where the local storage includes various situations, for example, along with configuration information that has been used last time, or, for another example, a plurality of configuration information is stored locally in advance, and when the configuration information needs to be obtained as the first configuration information, one configuration information is selected as the first configuration information according to a filtering condition, such as that the bandwidth is the largest, the spatial distance is the nearest, and the delay is the lowest.

Preferably, the local side electronic device obtains other configuration information besides the first configuration information, where the other configuration information may also be some information used to serve the establishment of the data transmission link, such as account information, rights information, verification information, and the like, and in some examples, the other configuration information is user-defined or customized personalized configuration information. Whether other configuration information is transmitted and content should depend on the specific situation of the connection to the shared server, for example, when the shared server needs to specify an account to log in, the other configuration information, such as account information, needs to be transmitted at this time, and for example, in order to ensure that data is not lost, an encryption verification algorithm may be specified and sent to the peer electronic device, and the peer electronic device may verify the received configuration information and/or the message on the data link.

The acquisition of the first configuration information may be performed after the APDU link is established, or may be performed when the identity information is acquired in step 201, which is not limited by the present application.

Step 302, sending the first configuration information to the opposite-end electronic device through the APDU link.

The local side electronic device sends the acquired first configuration information to the opposite side electronic device through the APDU link established in step 205, and the APDU command for sending the configuration information is called a configuration synchronization command, and similar to the above, the APDU command is a command APDU, the name of the INS field of the command is not limited, the name may be any, such as S, and the configuration information is placed in the data segment of the command.

After receiving the APDU instruction for configuration synchronization, the opposite-end electronic equipment reads configuration information in the instruction, which is the first configuration information at the moment, and establishes connection with the first sharing server according to the configuration information.

It should be noted that, since the command APDU can only store 0 to 255 bytes of data, when the configuration data and the local side identity information are large, the command APDU can be split into a plurality of request instructions and configuration synchronization instructions.

Preferably, the configuration synchronization instruction is used for transmitting other configuration information in addition to the first configuration information for connecting to the shared server.

The data in the configuration synchronization instruction can be plaintext or encrypted by using a secret key to implement asymmetric encryption transmission.

Step 303, connecting the first shared server according to the first configuration information, so as to establish a data transmission link with the peer electronic device through the first shared server.

The local electronic device establishes connection with the first shared server according to the first configuration information, a protocol for establishing the connection can be any such as HTTP, FTP, etc., a specific type of the protocol can be specifically determined according to data to be transmitted, so that the transmission is facilitated, and a determining process can be preset or specified in a configuration synchronization instruction.

The first shared server may be provided by an internet operator or a content service provider, for example, when the operator supports bip (Bearer Independent Call Control, bearer independent protocol), mms (Multimedia Messaging Service, multimedia short message service) and other data services, a data transmission link is established with the first shared server provided by the internet operator through configuration information.

Preferably, after the local electronic device and the first shared server are successfully connected, an auxiliary module such as a net module or a modem module is called to form SendData, recieveData two functional interfaces so as to solidify a data transmission link into an interface, thereby facilitating the call.

After the data transmission link is established successfully, the local electronic equipment can also monitor the data link by establishing a monitoring mechanism, wherein the monitored object not only comprises the data sent by the opposite electronic equipment, but also comprises the instruction or the data sent by the local electronic equipment, and further performs corresponding execution actions.

The local electronic device establishes a connection with the first shared server according to the first configuration information, and since the opposite electronic device also establishes a connection with the first shared server according to the first configuration information, the local electronic device and the opposite electronic device both establish another link with the first shared server, that is, both establish another link through the first shared server, and the link is referred to as a data transmission link in the present application.

Step 304, transmitting sharing information to the first sharing server through the data transmission link so that the first sharing server sends the sharing information to the peer electronic device, where the sharing information is sharing data or sharing data link.

The local electronic device may send the shared information to the peer electronic device via the data transmission link. Since the data transmission link is established via the first shared server, the routing of the shared information should be: the local electronic equipment sends the sharing information to a first sharing server, and the first sharing server forwards the sharing information to the opposite electronic equipment after receiving the data. In this embodiment, the shared information may be shared data such as audio and video, or may be a connection for acquiring the shared data such as a domain name.

Preferably, in some embodiments of the present application, the APDU link may be used to transmit a small amount of media data in addition to the operation command and the configuration information, for example, the APDU link may temporarily reserve to carry some data content when the server is abnormal.

Further, the operation instructions in step 206 include at least one of:

control instructions for the shared information and setting instructions for the opposite-end electronic equipment.

In this embodiment, the operation instructions are not only one, but also multiple operation instructions can be set to expand, so that the operation instructions can meet multiple requirements. For example, a shared information control instruction is provided, where the instruction is used to control shared information, such as when a multimedia module encoding and decoding the shared information is specified to play the shared information, or the shared information is specified to be delivered to a third party application to be embedded into a function of the third party application to play the shared information under control, or an electronic device at a peer end is specified to acquire data through a shared data connection, and so on.

Step 605, transmitting sharing information to the second sharing server through the data transmission link so that the second sharing server sends the sharing information to the peer electronic device, where the sharing information is sharing data or sharing data link.

Since the data transmission link in this embodiment is established via the second shared server, the routing of the shared information should be: the local terminal electronic equipment sends the sharing information to a second sharing server, and the second sharing server forwards the sharing information to the opposite terminal electronic equipment after receiving the data. In this embodiment, the shared information may be shared data such as audio and video, or may be a connection for acquiring the shared data such as a domain name.

step 701, acquiring the third configuration information, and sending the third configuration data to the opposite-end electronic device through the APDU link;

When the local side electronic device stores one or more configuration information in addition to the first configuration information, the local side electronic device may select new configuration information locally, which is referred to as third configuration information in this embodiment, in addition to the first configuration information.

After the new configuration information is acquired, that is, after the third configuration information is acquired, the local end electronic device sends a configuration synchronization instruction through the APDU link so as to synchronize the acquired third configuration information to the opposite end electronic device, and the data segment of the configuration synchronization instruction in the step encapsulates third configuration data.

Step 702, connecting the third shared server according to the third configuration information, so as to establish a data transmission link with the peer electronic device through the third shared server;

In some cases, the actions or steps recited in the claims can be performed in a different order than in the embodiments and still achieve desirable results. In addition, the processes depicted in the accompanying figures do not necessarily require the particular order shown, or sequential order, to achieve desirable results. In some embodiments, multitasking and parallel processing are also possible or may be advantageous.

Fig. 8 is a flowchart of a data transmission method according to a second embodiment of the present application, where the method is applied to a peer electronic device 102 in the data transmission system shown in fig. 1, and as shown in fig. 8, the data transmission method may include:

step 801, receiving an APDU link establishment request, and verifying local end identity information corresponding to the local end electronic device carried in the APDU link establishment request;

the opposite-end electronic equipment receives a request instruction sent by the local-end electronic equipment, wherein the format of the request instruction is a command APDU, and the instruction is used for requesting the opposite-end electronic equipment to establish an APDU link.

After receiving the request instruction, acquiring identity information carried in the instruction, wherein the identity information is self identity information stored in the local electronic equipment, and the opposite electronic equipment verifies the acquired identity information.

The request command is sent to the opposite terminal electronic equipment through PPP (Point-to-Point Protocol), and the sending and receiving of the command related to the APDU in the application are transmitted by adopting Point-to-Point Protocol (PPP).

Further, step 801 may further include:

step 11, receiving the APDU link establishment request, and obtaining locally stored identity information, wherein the locally stored identity information comprises the identity information of the local electronic equipment;

After receiving a request instruction sent by the local electronic equipment, acquiring identity information of the local electronic equipment stored in a local storage system, wherein the identity information can comprise: IMSI (International Mobile Subscriber Identity international mobile subscriber identity), temporary mobile subscriber identity (TMSI, temporary Mobile Subscriber Identity, ACCID user account identification, international mobile equipment identity (International Mobile Equipment Identity, IMEI), number, etc.

Preferably, after receiving a request instruction sent by the local electronic device, the information acquired from the local storage system not only includes the identity information of the local electronic device, but also includes the identity information of the opposite electronic device.

Under the condition that the data carried in the request instruction is ciphertext or encrypted communication is agreed, key information is also required to be obtained from the local storage system, wherein the key information comprises a public key and a private key of the opposite-end electronic equipment and a public key of the local-end electronic equipment.

And decrypting the ciphertext of the data segment in the request instruction by using the private key of the opposite-end electronic equipment so as to acquire the local-end identity information carried in the request instruction.

Step 12, verifying the local end identity information corresponding to the local end electronic device carried in the APDU link establishment request according to the locally stored identity information of the local end electronic device.

After the acquisition of the identity information in the local storage system is completed, verifying the identity information carried in the request instruction according to the identity information verification of the local electronic equipment stored in the local storage system.

Step 802, when the authentication of the identity information of the local end passes, sending a response message of the APDU request to the local end electronic device so as to establish an APDU link, where the response message carries the identity information of the opposite end electronic device.

And when the local end identity information passes verification, for example, when the local end identity information carried in the request instruction is consistent with the local end electronic equipment identity information stored in the local storage system, the verification passes. The verification indicates that the opposite-end electronic device successfully confirms that the device sending the request command is the local-end electronic device.

After the authentication of the local end identity information is successful, the opposite end electronic equipment sends a Response message to the local end electronic equipment, wherein the Response message is sent to the request instruction in a format of a Response APDU, the Response APDU comprises Response data (0 to 256 bytes of data) and a Response suffix (2 bytes of status words) of the SW1 to SW2, and the Response suffix can represent a command processing state, such as 90 00 (hexadecimal) represents success.

The data segment in the response message carries the identity information of the opposite-end electronic device, so that the local-end electronic device can confirm the identity of the device sending the response message, and confirm whether the device is the opposite-end electronic device. When the local electronic equipment confirms that the identity information is correct, the local electronic equipment is used as a communication initiator to complete a one-time request/response mode, so that the local electronic equipment can communicate with the opposite electronic equipment, and an APDU link is established with the opposite electronic equipment.

Similarly, the data segment in the response message may carry the identity information of the opposite-end electronic device in plaintext or ciphertext, for example, in the case that the data carried in the request instruction is ciphertext or is agreed to carry out encrypted communication, the public key of the local-end electronic device is used to encrypt the identity information of the opposite-end electronic device, and the ciphertext is encapsulated in the data segment in the response message.

After the authentication of the local end identity information is passed, the opposite end electronic equipment establishes an APDU link with the local end electronic equipment, wherein the link refers to a point-to-point protocol link/connection between the opposite end electronic equipment and the local end electronic equipment.

In fact, when the peer electronic device receives the request command, it has completed a peer-to-peer protocol communication, and synchronizes the state information required for the communication, such as that the peer electronic device and the local electronic device instantiate a same socket, and the state information indicates that the peer electronic device and the local electronic device can perform peer-to-peer protocol communication connection, and a communication link is established.

In this embodiment, the opposite-end electronic device does not consider the receiving request instruction as complete completion of communication connection, and further verifies the local-end identity information, and after the local-end identity information is verified, the opposite-end electronic device is considered as complete completion of one-time connection, and is successfully connected with the local-end electronic device in a communication manner.

It should be noted that, in this embodiment, the peer electronic device defaults to be the correct peer, and the local peer electronic device will successfully confirm the identity information carried in the response message, so that the peer electronic device can be regarded as successful connection establishment after the verification of the local peer identity information. Of course, in some embodiments of the present application, the default is the correct opposite terminal, after the authentication of the local terminal identity information is passed, the connection is not considered as being completed once, and only the authentication success message returned by the local terminal electronic device is received, the connection is considered as being completed, and the connection is successfully established.

Optionally, after the peer electronic device establishes the APDU link, that is, after the peer electronic device identity information in the request response message is successfully verified, the communication may be further cured into SendAPDU, recieveAPDU two special function interfaces by an auxiliary module, such as a net module or a modem module, according to the socket, so as to be conveniently invoked later.
