Description

Communication method, device, system, terminal, equipment and medium
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a communication method, apparatus, system, terminal, device, and medium.
Background
In the mobile interconnection era, intelligent hardware has unlimited prospects, and the intelligent hardware is as small as a bulb, a camera, a health scale and a sound box and as large as an electric cooker, a washing machine, a microwave oven and an air purifier. Especially, the intelligent sound box is taken as a representative and is used as a control center of an intelligent hardware family scene, and the real-time interactive experience of the intelligent sound box is particularly important.
At present, the control scenes of the intelligent sound box include two kinds, one is a close scene, namely, the sound box is near the user, and the user remotely controls the sound box in a close range; the other is a distant scene, namely, the sound box is not beside the user, and the sound box is remotely controlled.
In a close-range scene, a user can control through a terminal APP (Application) or bluetooth.
When the Control is performed through the terminal APP, data communication needs to be realized in a mode of bridging among servers, that is, as shown in fig. 1, the intelligent audio maintains data communication with the service server in a mode of long connection through a TCP (Transmission Control Protocol), and the APP sends a command to the service server in a mode of a HTTP (hypertext transfer Protocol) through the terminal where the APP is located, and then is issued to the intelligent audio by the server. Similarly, the real-time status and information of the smart audio needs to be transferred through the server before being sent to the terminal. Therefore, the problems of complicated information interaction process and poor real-time performance exist.
When control is performed through bluetooth, as shown in fig. 2, the smart audio and the terminal are connected to each other, so that information interaction can be performed through a bluetooth transmission band. However, the bluetooth transmission band is unstable, and the bluetooth connection distance is limited, so that the problem of poor real-time performance also exists.
Therefore, how to solve the problems of complicated information interaction and poor real-time performance in the controlled process of the electronic equipment in the prior art is a problem to be considered.
Disclosure of Invention
The invention discloses a communication method, a communication device, a communication system, a communication terminal, communication equipment and a communication medium, which are used for solving the problems of complicated information interaction and poor real-time performance when electronic equipment is controlled in the prior art.
To achieve the above object, according to an aspect of the present invention, there is provided a communication method including:
receiving a first connection request which is sent by a terminal and establishes connection with a remote controlled device, wherein the first connection request carries identification information of the remote controlled device;
and establishing a User Data Protocol (UDP) channel for the terminal and the remote control device according to the first connection request, and sending an IP address and a port number of the UDP channel to the terminal and the remote control device, so that the terminal and the remote control device communicate based on the IP address and the port number.
As can be seen from the above, after receiving a first connection request sent by a terminal and establishing a connection with a remote controlled device, a P2P server may determine a corresponding remote controlled terminal according to identification information of the remote controlled device carried in the first connection request, and establish a UDP channel for the terminal and the corresponding remote controlled device by using a mode of allocating a port number through a fixed IP based on the P2P technology, so as to implement direct communication between the terminal and the remote controlled device based on an IP address and a port number of the UDP channel, thereby overcoming the problems of cumbersome information interaction and poor real-time performance existing in the controlled process of an electronic device in the prior art.
Specifically, before the receiving terminal sends a first connection request for establishing a connection with a remote controlled device, the method further includes:
receiving a first registration request sent by the terminal and a second registration request sent by the remote control device, wherein the first registration request carries identification information of the terminal, and the second registration request carries identification information of the remote control device;
sending the identification information of the terminal and the remotely controlled equipment to a service server, so that the service server verifies whether the terminal and the remotely controlled equipment are legal or not;
and if the verification passing information sent by the service server is received, executing the subsequent steps.
Since the network accessed by the P2P server is a public network and the network accessed by the terminal and the remote control device is a private network, in order to ensure that the terminal and the remote control device which penetrate through the public network accessed by the P2P server are both legal devices, before establishing a UDP channel for the terminal and the remote control device, the P2P server firstly sends the identification information carried in the registration information of the terminal and the remote control device to the service server, and verifies whether the terminal and the remote control device are legal or not according to the identification information by the service server, so as to ensure network security and communication security.
Specifically, after establishing a UDP channel for the terminal and the remote controlled device according to the first connection request, the method further includes:
monitoring heartbeat packets sent by the terminal and the remotely controlled equipment, wherein the heartbeat packets carry verification information of corresponding equipment;
and if the heartbeat packet is not monitored or the verification information in the monitored heartbeat packet is invalid, disconnecting the DUP channel between the terminal and the remote control device.
In order to ensure that the P2P server can track the states of the terminal and the remote-controlled device, the P2P server monitors heartbeat packets sent by the terminal and the remote-controlled device, and when the P2P server does not monitor the heartbeat packets or verification information carried in the monitored heartbeat packets is invalid, a DUP channel between the terminal and the remote-controlled device is automatically disconnected, so that network security and communication security are further ensured.
According to another aspect of the present invention, there is also provided a communication method, including:
sending a first connection request for establishing connection with a remote-controlled device to a P2P server, so that the P2P server establishes a UDP channel for the terminal and the remote-controlled device, wherein the first connection request carries identification information of the remote-controlled device;
and receiving the IP address and the port number of the UDP channel sent by the P2P server, and communicating with the remote control device based on the IP address and the port number.
It can be seen from the above that, by sending the first connection request for establishing connection with the remote controlled device to the P2P server, the P2P server can determine the corresponding remote controlled terminal according to the identification information of the remote controlled device carried in the first connection request, and establish a UDP channel for the terminal and the corresponding remote controlled device by using a mode of allocating a port number by using a fixed IP based on the P2P technology, so that the terminal can directly communicate with the remote controlled device by using the IP address and the port number of the UDP channel, thereby overcoming the problems of cumbersome information interaction and poor real-time performance existing in the controlled process of the electronic device in the prior art.
Wherein before sending the first connection request for establishing connection with the remote controlled device to the P2P server, the method further comprises:
and sending a first registration request to the P2P server, wherein the first registration request carries the identification information of the terminal, so that the P2P server sends the identification information of the terminal to a service server, and the service server verifies whether the terminal is legal or not.
That is to say, before sending the first connection request to the P2P server, the terminal needs to send a registration request to the P2P server, so that the P2P server sends the identification information carried in the registration request to the service server, and the service server verifies whether the terminal is a valid user, so as to ensure network security and communication security.
Specifically, if the IP address and the port number of the UDP channel sent by the P2P server are not received within a first preset time period, the method further includes:
sending a second connection request for establishing connection with the remote control device to a service server;

and if first verification passing information sent by the service server is received, wherein the first verification information carries the IP address of the UDP channel, communicating with the remote control device based on the IP address and a first predicted port number.
When the terminal does not receive the IP address and the port number of the UDP channel sent by the P2P server, the terminal is not connected to the public network accessed by the P2P server in a penetrating way, at the moment, the terminal sends a second connection request to the service server, if the service server receives the IP address and the port number sent by the remote control device, the remote control device is connected to the public network accessed by the P2P server in a penetrating way, so the service server sends a preset random algorithm to the terminal after receiving the second connection request, the terminal determines a first predicted port number of the UDP channel by adopting a port guessing way according to the preset random algorithm, and when the first predicted port number is verified to be correct, the service server sends first verification passing information carrying the IP address of the UDP channel to the terminal, so that the terminal can directly communicate with the remote control device based on the IP address and the first predicted port number, therefore, the terminal can automatically establish a UDP channel with the remote control device under the condition that the terminal is not connected with the public network accessed by the P2P server in a penetrating way, and the remote control device is connected with the public network accessed by the P2P server in a penetrating way.
Specifically, the method further comprises:
sending control signaling to the remote controlled device based on the UDP channel;
if the response message sent by the remote control device is not received within a second preset time span, sending the second connection request to a service server, so that the service server sends a preset random algorithm to the remote control device;
and if second check-up passing information sent by the service server is received, communicating with the remote-controlled equipment based on the IP address and the port number of the UDP channel, wherein the second check-up passing information is sent when the service server checks up the second predicted port number of the UDP channel established by the P2P server according to the preset random algorithm to the remote-controlled equipment according to the port number of the UDP channel sent by the terminal.
If the terminal can send a control instruction to the remote control device based on the UDP channel but does not receive response information returned by the remote control device, the terminal can penetrate through the public network accessed by the P2P server and the remote control device does not penetrate through the public network accessed by the P2P server, at this time, the terminal sends a second connection request to the service server, so that the service server sends a preset random algorithm to the corresponding remote control device according to the identification information carried in the second connection request, so that the remote control device determines a second predicted port number of the UDP channel by adopting a port guess mode according to the preset random algorithm, and the service server sends second verification passing information to the terminal when the second predicted port number is verified to be correct, so that the terminal can directly communicate with the remote control device based on the IP address and the port number of the UDP channel, the remote control device is enabled to automatically establish a UDP channel with the terminal under the condition that the terminal can penetrate through the public network connected to the P2P server and the remote control device is not penetrated through the public network connected to the P2P server.
According to another aspect of the present invention, there is also provided a communication method, including:
and receiving the IP address and the port number of the UDP channel sent by the P2P server, and communicating with the terminal based on the IP address and the port number.

Specifically, before receiving the IP address and the port number of the UDP channel sent by the P2P server, the method further includes:
and sending a second registration request to the P2P server, wherein the second registration request carries the identification information of the remote controlled device, so that the P2P server sends the identification information of the remote controlled device to a service server, and the service server verifies whether the remote controlled device is legal or not.
That is, before the remote controlled device communicates with the terminal based on the IP address and the port number of the UDP channel sent by the P2P server, the remote controlled device needs to send a registration request to the P2P server, so that the P2P server sends the identification information in the registration request to the service server, and the service server verifies whether the remote controlled device is a valid user, so as to ensure network security and communication security.

Since the first connection request carries the identification information of the remote controlled device, the P2P server can determine the corresponding remote controlled device to which the terminal wants to establish a connection according to the identification information of the remote controlled device.
Step S303: and the P2P server establishes a UDP channel for the terminal and the remote control device according to the first connection request, and sends the IP address and the port number of the UDP channel to the terminal and the remote control device, so that the terminal and the remote control device communicate based on the IP address and the port number.
Step S304: and the terminal receives the IP address and the port number of the UDP channel sent by the P2P server and communicates with the remote control device based on the IP address and the port number.
Step S305: the remote controlled device receives the IP address and the port number of the UDP channel sent by the P2P server and communicates with the terminal based on the IP address and the port number.
It should be noted that, in the embodiment of the present invention, the network accessed by the P2P server is a public network, such as aristoloc, amazon, and the like, the network accessed by the terminal and the remote controlled device is a private network, and the terminal and the remote controlled device need to have a capability of accessing the public network. Because the private network IP can be directly communicated, the terminal and the remote control device can convert the private network IP address corresponding to the terminal and the remote control device into the public network IP through the network address translation NAT technology supported by the router, so that the terminal and the remote control device can be connected to the public network accessed by the P2P server in a penetrating manner.
Since the P2P is a peer-to-peer network, in the P2P network environment, the electronic devices connected to each other are all in a peer-to-peer status, so that when the terminal and the remote controlled device penetrate the public network accessed by the P2P server, the terminal and the remote controlled device communicate directly.
Specifically, when establishing a UDP channel for the terminal and the remote controlled device, the P2P server may use a mode in which a fixed IP allocates port numbers, where the fixed IP may be a public network IP obtained by converting a private network IP of the terminal through an NAT technique, or may be a public network IP obtained by converting a private network IP of the remote controlled device through an NAT technique. Since a router or an IP address can be provided with a plurality of devices, in order to ensure the uniqueness of the UDP channel used for communication between the terminal and the remote controlled device, a port number can be allocated to the UDP channel, wherein the port number is randomly generated by the P2P server through a preset random algorithm, so that the communication security of the UDP channel can be improved.
For example, the private network IP corresponding to the terminal is 192.168.1.101, and the public network IP converted by the router NAT technology is 120.78.201.201, so the record in the IP port mapping table on the router connected to the terminal is: [ 120.78.201.201 ] to [ 192.168.1.101 ]. The private network IP corresponding to the remote controlled device is 192.168.2.202, and the public network IP converted by the router NAT technology is 120.78.202.202, then the record in the IP port mapping table on the router connected to the remote controlled device is: [ 120.78.202.202 ] to [ 192.168.2.202 ].
When the P2P server receives a first connection request sent by the terminal to establish a connection with the remote controlled device, it determines the corresponding remote controlled device according to the identification information of the remote controlled device carried in the first connection request, and generates a random port number, for example 2020, by using a preset random algorithm. Then the UDP channels established by the P2P server for the terminal and the remotely controlled device may be 120.78.201.201: 2020, or 120.78.202.202: 2020.
if the IP address and the port number corresponding to the UDP channel established by the P2P server for the terminal and the remote control device are 120.78.201.201: 2020, after receiving the IP address and port number sent by the P2P server, the terminal adds one to the record in the IP port mapping table of its corresponding router: [ 120.78.201.201: 2020- [ 192.168.1.101 ], after receiving the IP address and the port number sent by the P2P server, the remote controlled device adds a record in the mapping table of the IP port of the corresponding router: [ 120.78.202.202: 2020- [ 192.168.2.202 ].
Therefore, when the terminal and the remote controlled device perform information interaction, the path of the information sent by the terminal is as follows: 192.168.1.101-120.78.201.201: 2020, the path of the received information is: 120.78.201.201: 2020-192.168.1.101. Similarly, the path of the information sent by the remote control device is as follows: 192.168.2.202-120.78.201.201: 2020, the path of the received information is: 120.78.201.201: 2020-192.168.2.202. Thus, the terminal and the remotely controlled device can be connected based on the UDP channel 120.78.201.201: 2020 enable direct communication.
Therefore, in the embodiment of the present invention, a UDP channel is established between the terminal and the corresponding remote controlled device by using a mode of allocating a port number through a P2P server based on a P2P technology, so that the terminal and the remote controlled device can directly communicate based on an IP address and a port number of the UDP channel, and therefore, forwarding through a service server is not required, and time for information interaction can be greatly shortened, thereby overcoming the problem of tedious signal interaction in a controlled process of an electronic device in the prior art.
It should be noted that there are three ways to implement NAT currently, namely Static NAT, Dynamic NAT, and port multiplex Over Load. The commonly used NAT traversal method for UDP channels mainly includes: the UDP of the NAT simply traverses STUN, the true traversal mode TURN of the NAT, and the like, which are not particularly limited in the embodiment of the present invention.
Example two:
to ensure network security and communication security during communication, on the basis of the above embodiment, in an embodiment of the present invention, before sending the first connection request for establishing connection with the remote controlled device to the P2P server, as shown in fig. 4, the communication method further includes:
step S401: the terminal sends a first registration request to the P2P server, wherein the first registration request carries the identification information of the terminal, so that the P2P server sends the identification information of the terminal to a service server, and the service server verifies whether the terminal is legal or not.
Step S402: the remote control device sends a second registration request to the P2P server, wherein the second registration request carries the identification information of the remote control device, so that the P2P server sends the identification information of the remote control device to a service server, and the service server verifies whether the remote control device is legal.
Step S403: and the P2P server receives a first registration request sent by the terminal and a second registration request sent by the remote control device.
Since the first registration request carries the identification information of the terminal and the second registration request carries the identification information of the remote controlled device, the P2P server will send the identification information of the terminal and the remote controlled device to the service server, that is, the following step S404.
Step S404: and sending the identification information of the terminal and the remotely controlled equipment to a service server.
Step S405: and the service server verifies whether the terminal and the remote control device are legal or not, and if the terminal and the remote control device are legal, the service server sends verification passing information to the P2P server.
That is, before the terminal sends the first connection request to the P2P server, both the terminal and the remotely controlled device need to register with the P2P server. Therefore, both the terminal and the remote controlled device need to send registration information to the P2P server, and the registration information carries identification information of itself, where the identification information may be an SN number for verifying whether the product of the terminal and the remote controlled device is a legal identity. After receiving the registration request sent by the terminal and the remote controlled device, the P2P server sends the corresponding device SN number carried in the registration request to the service server, and the service server verifies the SN numbers of the terminal and the remote controlled device respectively, and only if the verification is legal, the P2P server sends verification passing information to the P2P server.
Therefore, in the embodiment of the invention, the terminal accessing the P2P server and the remote-controlled device can be ensured to be legal devices by verifying the identities of the terminal and the remote-controlled device, thereby ensuring network security and communication security.
It should be noted that, in the embodiment of the present invention, in order to facilitate the registration of the terminal and the remotely controlled device in the P2P server, the P2P server preferably uses a fixed and shifted domain name or IP. And the terminal may include a mobile phone, a computer, a tablet computer, etc.
Example three:
because the router accessed by the terminal and the remote controlled device can convert the private network IP address corresponding to the terminal or the remote controlled device into the public network IP through the NAT technology, so as to enable the terminal and the remote controlled device to be capable of penetrating and accessing the public network where the P2P server is located, but because of the NAT limitation of the router, for example, the NAT of one router is an IP limitation type NAT, a port limitation type NAT or a symmetric NAT, it is possible that the access of the terminal or the remote controlled device is unsuccessful. Or due to firewall factors, for example, some firewalls analyze the application layer protocol, reject packets of some keywords, which is shown as that the firewall discards signaling packets related to P2P, or some firewalls analyze the declaration period of the link, reject the link which is not reasonable for him, which results in that the router shows as symmetric NAT, and possibly results in unsuccessful access of the terminal or the remote control device. Or the access of the terminal or the remote control equipment is not successful because the mobile gateway GPRS support node GGSN does not allow the access of the terminal to be interconnected and intercommunicated.
Therefore, on the basis of the above embodiment, in the embodiment of the present invention, as shown in fig. 5, the method further includes:
step S501: and if the terminal does not receive the IP address and the port number of the UDP channel sent by the P2P server within the first preset time length, sending a second connection request for establishing connection with the remote control equipment to the service server.
If the terminal does not receive the IP address and the port number of the UDP channel sent by the P2P server within 1min after the terminal sends the first connection request to the P2P server, it indicates that the terminal is not connected to the public network to which the P2P server is connected, at this time, the terminal sends a second connection request for establishing connection with the remote controlled device to the service server, so that the service server determines the corresponding remote controlled device, that is, the remote controlled device to which the terminal wants to connect, according to the identification information of the remote controlled device carried in the second connection request, and determines whether the remote controlled device is connected to the public network to which the P2P server is connected.
Step S502: after receiving the port number of the UDP channel sent by the P2P server, the remotely controlled device sends the IP address and the port number of the UDP channel to the traffic server.
If the service server can receive the IP address and the port number of the UDP channel sent by the remote control device, the remote control device can penetrate through the public network accessed by the P2P server, so that the service server can determine whether the terminal is the remote control device which the terminal wants to connect to according to the identification information of the remote control device.
It should be noted that step S501 and step S502 are not in strict sequence.
Step S503: and after receiving the IP address and the port number of the UDP channel sent by the remote control equipment and the second connection request sent by the terminal, the service server sends a preset random algorithm to the terminal.
That is, after determining that the remotely controlled device to which the terminal wants to connect can penetrate the public network connected to the P2P server, the traffic server sends the predetermined random algorithm to the terminal, wherein the predetermined random algorithm is the same predetermined random algorithm used by the P2P server to randomly generate the port number in the first embodiment, so that the terminal can guess the possible port number of the UDP channel by using the port guessing technique.
Step S504: and the terminal determines a first predicted port number of the UDP channel according to the preset random algorithm and sends the first predicted port number to the service server.
Step S505: and the service server checks whether the first predicted port number is correct according to the port number of the UDP channel sent by the remote control equipment, and if the first predicted port number is correct, first check passing information is sent to the terminal.
Step S506: and the terminal receives first verification passing information sent by the service server, wherein the first verification information carries the IP address of the UDP channel, and then the terminal communicates with the remote control device based on the IP address and a first predicted port number.
After the terminal obtains the preset random algorithm sent by the service server, a port guessing technology is adopted to guess a possible first predicted port number of the UDP channel, the first predicted port number is sent to the service server, and the service server checks the first predicted port number.
For example, the port number sent by the remote control device to the service server is 2020, and the possible first predicted port number of the UDP channel predicted by the terminal through the port guessing technology is also 2020, the service server determines that the check result is correct. At this time, the service server will send the first verification pass information to the terminal, and then the terminal will directly communicate with the remote controlled device based on the IP address and port number 2020 carried in the first verification pass information.
Therefore, in the embodiment of the present invention, when the terminal is not connected to the public network to which the P2P server is connected through penetration, and the remote control device is capable of being connected to the public network to which the P2P server is connected through penetration, the terminal may determine, by means of port guessing, the port number of the UDP channel received by the remote control device according to the preset random algorithm sent by the service server, so as to implement that, in a case where the terminal is not connected to the public network to which the P2P server is connected through penetration, and the remote control device is capable of being connected to the public network to which the P2P server is connected through penetration, as a better communication method, the terminal automatically establishes the UDP channel with the remote control device, and directly communicates with the remote control device based on the UDP channel, thereby overcoming the problems of tedious signal interaction and poor real-time performance in the controlled process of the electronic device in the prior art.
Example four:
on the basis of the above embodiment, in the embodiment of the present invention, as shown in fig. 6, the method further includes:
step S601: and after receiving the IP address and the port number of the UDP channel sent by the P2P server, the terminal sends the IP address and the port number of the UDP channel to the service server.
If the terminal can receive the IP address and the port number of the UDP channel sent by the P2P server, which indicates that the terminal can penetrate the public network connected to the P2P server, the terminal can send control signaling to the remote controlled device through the UDP channel, that is, the following step S602.
Step S602: and the terminal sends a control signaling to the remote control device based on the UDP channel.
Step S603: and if the terminal does not receive the response message sent by the remote control device within a second preset time length, sending a second connection request for establishing connection with the remote control device to a service server.
Assuming that the second preset time duration is 1min, if the terminal does not receive the response message sent by the remote control device within 1min after sending the control signaling to the remote control device, the terminal will determine that the remote control device is not connected to the public network accessed by the P2P server. At this time, the terminal sends a second connection request for establishing connection with the remote controlled device to the service server, where the second connection request carries identification information of the remote controlled device.
Step S604: and the service server sends a preset random algorithm to the remote control equipment.
Since the second connection request carries the identification information of the remotely controlled device, the service server determines the remotely controlled device to which the terminal wants to connect according to the identification information of the remotely controlled device carried in the second connection request, and sends a preset random algorithm to the remotely controlled device.
Step S605: and the remote control equipment receives the preset random algorithm sent by the service server.
Step S606: and determining a second predicted port number of the UDP channel according to the preset random algorithm, and sending the second predicted port number to a service server.
Similarly, the preset random algorithm is the same preset random algorithm used when the P2P server randomly generates the port number in the first embodiment. Therefore, after the remote control device obtains the preset random algorithm sent by the service server, a port guessing technology can be adopted to guess a possible second predicted port number of the UDP channel, the second predicted port number is sent to the service server, and the service server checks the second predicted port number.
Step S607: and the service server checks whether the second predicted port number is correct according to the port number of the UDP channel sent by the terminal, and if the second predicted port number is correct, second check passing information is sent to the terminal and the remote control device.
For example, the port number sent by the terminal to the service server is 2020, and the possible first predicted port number of the UDP channel predicted by the remote control device through the port guessing technique is also 2020, the service server determines that the check result is correct.
And when the check result is correct, the service server can check the passing information to the remote controlled equipment for the second time, so that the remote controlled equipment can communicate with the terminal based on the IP address and the second predicted port number carried in the second checking passing information. Meanwhile, the service server also checks the pass information to the terminal so that the terminal knows that the remote controlled device can connect to the UDP channel, and then directly communicates with the remote controlled device according to the IP address and the port number sent by the P2P server, i.e. the subsequent steps S608 and S609.
Step S608: and the terminal receives the second check passing information sent by the service server and communicates with the remote control device based on the IP address and the port number of the UDP channel.
Step S609: and the remote control device receives second check passing information sent by the service server, wherein the second check passing information carries the IP address of the UDP channel and is communicated with the terminal based on the IP address and a second predicted port number.
Therefore, in the embodiment of the present invention, when the terminal is connected to the public network accessed by the P2P server in a penetrating manner, and the remote control device is not connected to the public network accessed by the P2P server in a penetrating manner, the remote control device may determine the port number of the UDP channel received by the terminal in a port guessing manner according to the preset random algorithm sent by the service server, so as to implement, as a better communication manner, that the remote control device automatically establishes the UDP channel with the terminal and directly communicates with the terminal based on the UDP channel in a case that the terminal is capable of being connected to the public network accessed by the P2P server in a penetrating manner, and the remote control device is not connected to the public network accessed by the P2P server in a penetrating manner.
Example five:
as can be seen from the above description, in the embodiment of the present invention, the process of the P2P server establishing the UDP channel for the terminal and the remote control device is specifically as follows:
first, as shown in fig. 7, the terminal and the remote controlled device are registered in the P2P server.
When the terminal and the remote-controlled device are successfully registered in the P2P server, that is, as shown in fig. 8, the P2P server obtains the IP addresses of the terminal and the remote-controlled device, respectively, and assigns terminal numbers to the terminal and the remote-controlled device, so that the terminal and the remote-controlled device realize point-to-point penetration, and perform information transmission.
However, when one of the terminal or the remotely controlled device fails to penetrate, the service server forwards information for the terminal or the remotely controlled device, so that when one of the terminal or the remotely controlled device fails to penetrate, a UDP channel with the other one is automatically established, and direct communication is performed based on the UDP channel.
Therefore, in the embodiment of the invention, when both the terminal and the remote-controlled device can be connected to the public network accessed by the P2P server in a penetrating way, the P2P server can directly establish a UDP channel for the terminal and the remote-controlled device, so that the terminal and the remote-controlled device can directly communicate through the UDP channel. When one of the terminal or the remote control device fails to penetrate, the terminal or the remote control device can forward information through the service server, automatically establish a UDP channel with the other party and directly communicate based on the UDP channel, so that the transmission of a control instruction by using the service server as a third party is not needed, the time of information interaction is greatly shortened, and the problem of complicated signal interaction in the prior art is solved.
Example six:
after the P2P server establishes the UDP channel for the terminal and the remote controlled device, to further ensure network security and communication security, on the basis of the foregoing embodiment, in an embodiment of the present invention, the method further includes:
monitoring heartbeat packets sent by the terminal and the remote control equipment, wherein the heartbeat packets carry verification information of corresponding equipment;
and if the heartbeat packet is not monitored or the verification information in the monitored heartbeat packet is invalid, disconnecting the DUP channel between the terminal and the remote control device.
The heartbeat packet is information sent by the terminal or the remote controlled device to the P2P server at a certain time interval, and the heartbeat packet also carries authentication information of the terminal or the remote controlled device. Therefore, the P2P server can monitor the status of the terminal or the remote control device by monitoring the heartbeat packet sent by the terminal or the remote control device.
Therefore, when the P2P server does not monitor the heartbeat packet sent by the terminal or the remote controlled device, or the verification information carried in the heartbeat packet sent by the terminal and the remote controlled device is not the preset verification information, the P2P server will automatically disconnect the DUP channel between the terminal and the remote controlled device, so as to ensure the network security and the communication security.
