In the present invention, the publishing terminal is used for publishing service information, and the mobile terminal is used for receiving service information.

As shown in FIG. 2A and FIG. 2B , in the embodiment of the present invention, the user A of the publishing terminal 10 first generates service information and service address information corresponding to the service information through the first application installed on the publishing terminal 10 based on the NSD technology, The service information includes the service name, and of course authentication information can be generated. The first application can be an application such as a chat room or a local area network game, and the service address information is entered into the NFC tag 30 through the first application. That is, the first application in this embodiment includes at least two functions: one function is to generate information based on the NSD technology, such as service information and service address information corresponding to the service information, and the other function is to be able to record information into the NFC tag 30 middle. The NSD protocol format of the service information in this embodiment is shown in Table 1, and may include two parts, WiFiDirect network access information and a service name. The access information is parsed by the NSD protocol itself, which is used to connect the WiFiDirect network, and the service name is parsed by a second application program, which can be compatible with the first application program. QQ generates service information and service address information corresponding to the service information, and enters the service address information into the NFC tag, and the service address information can also be obtained by parsing the NFC tag through QQ. In addition, the service information in this embodiment may further include a communication method for publishing the service information. Optionally, the service name may also be included in the NFC tag.

It is a constrained private service. The written service address information in NSD format follows the NFC tag standard and is written into the NFC tag, which will not be repeated here. Of course, the information entered in the NFC tag 30 may also include a service name. In addition, the information written into the NFC tag may also include authentication information, such as an authentication code, that needs to be input when performing information interaction with the issuing terminal 10 .

Table 2

Next, as shown in Figure 220, user A uses the publishing terminal 10 to publish the service information through the WiFiDirect network using the NSD protocol. Specifically, the service information is sent to the server of the WiFiDirect network, and after the server receives the service information, the network uses The broadcast signal method is used to publish the service information. Of course, the user A can directly publish the service information in the WiFiDirect network through the publishing terminal 10. The service information can at least include the service name. When the WiFiDirect network is used, it can also be shown in Figure 1. It includes WiFiDirect network access information, service name such as XX brand discount and promotion, and communication method such as using QQ for interaction. Specifically, the server of the WiFiDirect network parses the access information of the WiFiDirect network based on the NSD protocol. After the access information is passed, the user A can publish the relevant information of the service information in the WiFiDirect network through the publishing terminal 10 through QQ and broadcasting.

For example, the user A sets the NFC tag 30 storing the service address information on the bulletin board of a cafe that can be covered by the WiFiDirect network. Of course, the NFC tag 30 may also include authentication information, and the authentication information is used to prevent criminals from maliciously accessing the WiFiDirect network and occupying network resources.

When the user B of the mobile terminal 20 enters a coffee shop with the mobile terminal 20, it receives the broadcast signal sent by the publishing terminal 10 based on the NSD protocol through the WiFiDirect network of the coffee shop. QQ obtains the service name and communication method from the broadcast signal, such as XX brand discount and QQ software, and then displays the service name on the screen of the mobile terminal 20 . If user B is interested in the service name of XX brand discount promotion, the NFC tag 30 corresponding to the service name can be found on the bulletin board of the cafe.

User B of the mobile terminal 20 brings the mobile terminal 20 close to the NFC tag 30 , and QQ in the mobile terminal 20 acquires the service address information and authentication information in the NFC tag 30 . After the mobile terminal 20 obtains the service address information through the NFC module, it is sent to the processor, and the processor identifies the service address information through the QQ that supports the communication mode, and then the processor reads the executable program code stored in the memory to identify the service address information. Running the program corresponding to the executable program code, as shown in step 221, initiates the NSD service connection, establishes the physical connection of the WiFiDirect network, and establishes a connection with the publishing terminal 10 based on the WiFiDirect network through the WiFi port 211. After the right, as shown in step 222, the WiFiDirect network connection is successfully established, and the mobile terminal 20 accesses the WiFiDirect network, that is, the terminal receives the connection request sent by the mobile terminal, and establishes a point-to-point communication connection with the mobile terminal based on the WiFiDirect network. The mobile terminal uses QQ Information exchange is performed with the publishing terminal 10, as shown in step 223, the interaction is performed according to the private protocol agreed upon by QQ. Wherein, the processor, the memory and the communication interface are connected through a bus.

Specifically, the second application in the mobile terminal 20 has at least the following three capabilities: reading the NFC tag and acquiring service address information, parsing the service address information, and establishing a communication connection with the issuing terminal 10 .

The QQ name of the mobile terminal 20 displayed by the user B's QQ to the user A may be a certain name designated by the user B, rather than the name matching the user B's QQ number. User A's QQ name displayed to user B by user A's QQ is also a name specified by user A, rather than the name matching user A's QQ, so as to avoid leakage of privacy of both parties.

This embodiment provides a communication method for establishing a communication connection between two terminals within a small range without using the Internet, for example, within a small range of tens of meters or hundreds of meters. The execution body of this embodiment is a mobile terminal. As shown in FIG. 3A , it is a schematic flowchart of the communication method according to this embodiment. The communication method of this embodiment includes:

Step 101: Receive a broadcast signal, where the broadcast signal includes service information, and the service information includes a service name.

A local area network refers to a group of computers interconnected by multiple computers in a certain area. The local area network has the following advantages: 1. The baseband transmission is used, and the transmission speed is high; 2. The network coverage area is small, and a modem is not required; 3. The transmission error rate is low. In this embodiment, the separation distance between the mobile terminal and the terminal for issuing service information is relatively small, generally within a few hundred meters.

The local area network in this embodiment may be a WiFiDirect network, which allows wireless communication devices to be interconnected in a point-to-point form, and the communication distance is about 200 meters.

Specifically, broadcast signals may be received through a local area network based on an NSD (Network Service Discovery, Network Service Discovery) protocol. The NSD protocol allows the terminal to identify the device in the local area network in order to support the service request in the terminal application.

The service information in this embodiment may include many contents, such as service name, software capable of establishing a communication connection with the publishing terminal that publishes the service information, and the like.

Step 102: Acquire service information through the information storage portable device corresponding to the service name.

For example, the information storage portable device in this embodiment may be NFC (Near Field Communication, short-range wireless communication technology), which is a short-range high-frequency wireless communication technology that allows non-communication between electronic devices within a short distance. Contact point-to-point data transfer exchanges data. With just one touch, data can be exchanged between different terminals. The NFC tag is a chip with rewritable input, which stores NFC information, which can be transmitted by electromagnetic induction coupling in the radio frequency part of the spectrum.

The information storage portable device in this embodiment stores at least service address information. In the embodiment, different information storage portable devices correspond to different service names, and information storage portable devices with corresponding service information can be found according to the corresponding service names.

The service information may be the address information of the publishing terminal of the service information, and may also include the service name and/or the service access password specified by the user of the publishing terminal, so as to be used for establishing a communication connection between the mobile terminal and the publishing terminal. Including means of communication.

Step 103: Establish a point-to-point communication connection with the service information publishing terminal based on the service address information based on the local area network, so as to perform information exchange.

After acquiring the service address information, the mobile terminal can establish a point-to-point communication connection with the publishing terminal having the service information of the service address information, which may be based on any protocol or network that can provide a point-to-point communication connection. The point-to-point communication connection means that each client connects to each other for data transmission without going through the server in the Internet, which can greatly speed up the download speed of data and avoid network congestion caused by poor server performance and low bandwidth.

Specifically, a peer-to-peer communication connection can be established based on the WiFiDirect network according to the service address information and the issuing terminal of the service information.

According to the communication method of this embodiment, when communicating between two terminals in a small area, a broadcast signal with a service name is first received, thereby avoiding the defect that terminal users need to manually search for service information. Store the portable device to obtain the service address information. Users in need can obtain the service address information through the information storage portable device, which is very convenient and fast, and can not rely on the Internet as much as possible, that is, the dependence on the Internet is small. In addition, this solution does not rely on social networking. The application is a lightweight solution that will not lead to the leakage of personal information, protect user privacy, improve security, and establish a point-to-point connection with the publishing terminal through the service address information, which can avoid the need to use the Internet to establish a communication connection. And this brings too much burden to the Internet.

Step 201: Receive a broadcast signal, where the broadcast signal includes service information, where the service information includes a service name and a communication method for publishing the service information by the publishing terminal.

A local area network refers to a group of computers interconnected by multiple computers in a certain area. The local area network has the following advantages: 1. The baseband transmission is used, and the transmission speed is high; 2. The network coverage area is small, and a modem is not required; 3. The transmission error rate is low. In this embodiment, the separation distance between the mobile terminal and the terminal for issuing service information is relatively small, generally within a few hundred meters.

Optionally, after the application program supporting the communication method information is obtained by using the communication method, it can be first judged whether there is a first application program or a second application program in the mobile terminal, and if the judgment result is no, the first application can be downloaded and installed. The program or the second application program, if the judgment result is yes, the operation of acquiring the service name in the broadcast signal through the first application program or the second application program installed in the mobile terminal can be directly performed.

Step 203: Acquire the service address information through the information storage portable device corresponding to the service name.

Specifically, the information storage portable device can be distributed in multiple locations within the coverage of the local area network. After the mobile terminal obtains the service name, it can search for the information storage portable device corresponding to the service name. Of course, the broadcast information may also include the address of the information storage portable device corresponding to the service name, so that the end user can directly find the location of the information storage portable device. More specifically, the information storage portable device can be marked with a service name, so that the end user can know which information storage portable device corresponds to the service name he is interested in, and then can obtain the corresponding service address information from the information storage portable device. After determining the information storage portable device corresponding to the service name, the terminal user can hold the mobile terminal close to the preset information storage portable device, and then obtain the corresponding service address information.

Step 204 , establish a point-to-point communication connection with the publishing terminal by means of communication according to the service address information based on the local area network, so as to perform information exchange.

If the local area network itself supports the establishment of a point-to-point communication connection between the mobile terminals, the step 204 may specifically be: establishing a point-to-point communication connection with the publishing terminal by means of communication according to the service address information.

For example, if the software supporting the communication method is QQ, the communication connection between the publishing terminal and the mobile terminal can be established through QQ. At this time, the information displayed by the user of the publishing terminal may be the name set by the publishing terminal in the service information, such as "Shampoo Discount Promotion", that is, even if the interaction between the two terminals uses QQ, the You can't see the other party's QQ number, but you can only see the name used by the users of both parties for peer-to-peer communication, so as to avoid privacy leakage. Of course, users can also set the other party to be able to see some of their private information, such as QQ numbers, according to actual needs, and then they can exchange information through the Internet after leaving the current local area network.

According to the communication method of this embodiment, when communicating between two terminals in a small area, a broadcast signal with a service name is first received, thereby avoiding the defect that terminal users need to manually search for service information. Store the portable device to obtain the service address information and communication method. Users in need can obtain the service address information through the information storage portable device, and identify it through the application program that supports the communication method, which is very convenient and fast, and can try not to rely on the Internet, that is, It has little dependence on the Internet. In addition, this solution does not rely on social applications. It is a lightweight solution that will not lead to the leakage of personal information, protect user privacy, improve security, and establish a connection between the terminal and the publishing terminal through the service address information. The point-to-point connection can try to avoid the problem of using the Internet to establish a communication connection and thus bring too much burden to the Internet.

Step 210, generating service information and service address information corresponding to the service information, and setting the service information in the information storage portable device;

In step 210, authentication information may also be generated, and the authentication information may be entered into the information storage portable device. After the mobile terminal obtains the authentication information, the mobile terminal accesses the local area network through the authentication information.

Step 211, using the broadcast signal mode to publish the service information, the service information includes the service name, so that the mobile terminal receiving the broadcast signal obtains the service address information through the information storage portable device corresponding to the service name, and the service address information is used to establish communication with the publishing terminal. connect;

Step 212: Receive a connection request from the mobile terminal, and establish a point-to-point communication connection with the mobile terminal based on the local area network for information exchange.
