This application provides communication connecting method, device, system and storage medium, the method, apparatus and system are answered System architecture, as shown in Figure 1.The system architecture includes: the first equipment 101, the second equipment 102, router 103 and application Server 105.Wherein, the first equipment 101 and the second equipment 102 are in the same local area network, all by router 103 and mutually 104 connection of networking, router 103 are connect with application server 105 by internet 104.First equipment 101 and the second equipment After 102 connect wifi, distributed under the first equipment 101 and the respective unique private ip of the second equipment 102 by router, and This IP sections of distribution belongs to invisible to internet.First equipment 101 can be portable mobile termianl, such as mobile phone, PDA It can be the communication connection box of equipment Deng, second equipment 102, such as the TV box of TV, which can be With the independent equipment of the equipment, it is also desirably integrated into the equipment.First equipment 101 and the second equipment 102 may be implemented The TV box of mobile phone and TV in communication connection in local area network, such as the same local area network, mobile phone is by the figure on mobile phone Piece is sent to TV box by local area network, and TV box shows the picture received on TV.

In some instances, two equipment in local area network are communicated if necessary, the first equipment of example as shown in figure 1 101 will be communicated with the second equipment 102, by the way of issuing again through application server transfer.For example, the first equipment 101 It is communicated between the second equipment 102, the second equipment 102 and the first equipment 101 are all established with remote application server 105 and connected It connects, data are sent to remote application server via identical subscriber identity information by the second equipment 102 or the first equipment 101 105, remote application server 105 is forwarded back to again according to subscriber identity information come another party.For example, the first equipment 101 is mobile phone, Second equipment 102 is TV box, when the picture on mobile phone is sent to TV box by user, and then displaying on TV When, the picture on mobile phone is first sent to long-range application server 105, and application server 105 is sent by the picture received TV box is given, and then is shown on TV.The program transmits real-time and efficiency of transmission is all very low, when data volume is big, prolongs The slow time is long, and the resource at 105 end of application server is also bigger.

In other examples, when the first equipment 101 will be communicated with the second equipment 102, without remote application service Device 105 carries out transfer and establishes tcp connection in a local network based on the private ip in local area network, port, transmit data again later. In a local network, it is just distributed since private ip is connected into after wifi, the ground of port also not public record.Such as it is same Mobile phone and TV box under wifi will carry out tcp communication, it is necessary to which one knows private ip in the local area network of another party, end Slogan, to initiate the tcp connection of a standard.To send TV box for the content on mobile phone, and then throws screen and arrive TV For, it can the publicly-owned consensus standard based on DLNA or the scheme based on the privately owned airplay agreement of apple.Mobile phone and TV box On applications client will be installed, which will can be realized the agreement of DLNA or the privately owned airplay based on apple Agreement.In the application starting for providing service one side (such as TV box), in a local network by the TV box oneself monitored Private ip, port numbers are broadcasted in a manner of the IP broadcast of local area network to the whole network.Wish the side initiated the connection, such as mobile phone, according to association Quasi- listening broadcast message of assessing a bid for tender just will recognise that more at this time if there is multiple TV boxes for providing and servicing under same local area network A TV box, while obtaining the private ip and port numbers of each TV box.User selects some box to connect at this time, Specifically, it according to the private ip and port numbers of the TV box of selection, establishes and communicates to connect with the TV box, and then after progress Continuous data transmission.

In this example, the both sides communicated must install app, the field that this behavior uses user once in a while For scape, cost is excessively high, for example, user may only for provisional communication once, it is also necessary to downloading installation one app.In addition, obtaining The private ip and port numbers and subsequent communication process of communication counterpart, all in local area network, if the router of local area network or Firewall shields IP broadcast, then communication connection can not establish.The example is also larger to the stability dependency of home environment.

In order to solve the above technical problems, present applicant proposes a kind of communication connecting methods, set using shown in Fig. 1 first Standby 101, as shown in Fig. 2, method includes the following steps:

Step 201: when the first page in response to being shown to the first equipment operation and determination will be in local area network When two equipment establish connection, page data request is sent to application server by wide area network.

When the first equipment 101 will be established with the second equipment 102 to be communicated to connect, the first equipment 101 is by wide area network to remote The application server request page data of journey, the wide area network can be internet.For example, when the first equipment 101 is that hand is mechanical, electrical The mobile terminals such as brain, PD, the second equipment 102 be the TV box period of the day from 11 p.m. to 1 a.m, by mobile terminal picture or video be sent to TV box Son, and then when carrying out large-size screen monitors viewing on TV, first mobile terminal are to application server request page data, the page data In include logical code for being attached and communicating with TV box.User can pass through multiple entry requests in movement The page data, and then according to the page data displayed page, which is the HTML5 page (h5) page, such as user can To input the website of the h5 page in a browser, thus to the page data of the application server request h5 page.In addition, user Wechat public platform can also be clicked in wechat, to the page data of the application server request h5 page, the public as shown in Figure 3 In number page, public platform when the user clicks: when connecting the icon 301 of equipment, page processing template in wechat is to application service Device requests h5 page data.

For the process of specific page data request, the page processing template in the first equipment first asks page data Message is asked to be sent to router 103, when user requests h5 page data in such a way that browser inputs network address, at the page Reason template is browser, and when user requests h5 page data by the public platform in wechat, which is wechat In browser module.In the page data request message include the first equipment be private ip in a local network, wherein when first After equipment access to LAN, the first equipment private ip is distributed to by router.Router 103 is according to the private ip of first equipment Determine that the outlet IP of first equipment, router record the outlet IP and corresponding private ip of first equipment, Jin Ergen simultaneously The request message is sent to application server according to the outlet IP.

Step 202: being sent by application server responses described in the wide area network reception in the page data request Page data.

As depicted at step 201, after page data request message is sent to application server by the first equipment, application service Page data corresponding with the request message is returned to routing 103 by device, the network packet of page data described in simultaneous transmission The outlet IP of first equipment is carried in packet header, after router receives the network packet, obtains going out for first equipment Mouth IP, while the corresponding relationship of the outlet IP and private ip according to record, determine the private ip of first equipment, and then basis The page data is sent to first equipment by the private ip of first equipment.Include in the page data to The logical code that second equipment is communicatively coupled.

Step 203: obtaining private ip and port numbers of second equipment in the local area network.

When the first equipment will be established with the second equipment in the same local area network to be communicated to connect, in addition to needing step 202 Logical code in the page data of middle acquisition to execute connection, while also needing the second equipment in a local network privately owned IP and port numbers.The private ip and port numbers of the second equipment are obtained, the same of page data request can be sent to application server When, the private ip and port numbers of the second equipment are obtained by application server, and then the first equipment is returned to together with page data； The private ip and port numbers of the second equipment can also be obtained by way of scanning the graphical identification code of the second equipment.

Step 204: by executing the logical code in the page data, according to the private ip of second equipment And port numbers, establish first equipment and communication connection of second equipment in the local area network.

It include establishing connection with the second equipment in local area network to realize in the page data obtained in step 202 Logical code executes the logical code when establishing with the connection of the second equipment, according to the second equipment in a local network privately owned IP and port numbers establish the communication connection with the equipment.Subsequent data transmission can be carried out after establishing communication connection.

When establishing communication connection with the second equipment, long-range application server request h5 page data is accessed first, is visited The domain name for the server asked is the domain name of remote application server, and when being attached with the second equipment, second in local sets It is standby, such as the TV box of TV, it is impossible to possess domain name, so there can be cross-domain access problem.Such as using ajax or The cross-domain technology of the tradition such as iframe, can make volume of transmitted data small, and can not two-way communication.Thus the application communication connecting method It has selected using websocket communication plan, wherein the h5 page supports websocket protocol standard, can not only solve cross-domain The problem of access, can also be realized and establish two-way communication, and the connection data established with the second equipment in the same local area network Transmission quantity is big.

Using communication connecting method provided by the present application, the first equipment (such as mobile terminal) in local will be set with second When standby (such as TV box) establishes connection, to by the media content in the first equipment throw screen to the second equipment is associated sets When showing on standby (such as TV), do not need additionally to install using APP, it is only necessary to open a h5 page, execute the h5 page Logical code in page data realizes the communication connection with the second equipment, and the h5 page supports websocket protocol mark Standard can realize duplex communication with the second equipment, and the communication connection established, volume of transmitted data are big.

In some instances, wherein include the outlet IP of first equipment in the page data request, in above-mentioned step In rapid 203, when executing the private ip and port numbers for obtaining second equipment in the local area network, including following step It is rapid:

Step S11: the application server responses are received and are existed in second equipment that the page data request is sent Private ip and port numbers in the local area network, wherein private ip and port numbers of second equipment in the local area network It is determined by the application server according to the outlet IP of first equipment.

In this example, the second equipment private ip in a local network and port numbers, the reality are obtained from application server Example is based on the first equipment 101 and the outlet IP having the same of the second equipment 102.The private of the second equipment is preserved at application server There are IP and port numbers, and the private ip and port numbers are associated with preservation with the outlet IP of second equipment.What the second equipment was initiated It include the outlet IP of first equipment in the page data request, application server is receiving the page data request When, other than obtaining page data corresponding with the page data request, also according to the outlet IP of first equipment, look into The private ip and port numbers of the second equipment of identical outlet IP are looked for, and second equipment with identical outlet IP will be found Private ip and port numbers are transmitted across first equipment together with the page data.It is multiple with phase when existing in a local network When with the second equipment for exporting IP, application server can send out the private ip of the multiple second equipment found and port numbers Give first equipment.
