Background technique

In recent years, with the rapid development of mobile Internet technology, mobile phones have gradually replaced personal computers (PCs) as the central node of personal data and computing. Sharing mobile content (such as photos, videos, or music) over a wireless network to other devices (such as TVs, PCs, or mobile phones) and implementing multi-screen interactive technology that controls each other has emerged. The premise of sharing and mutual control between devices is that they can discover each other, so the discovery protocol between devices becomes a core component of the interactive technology between devices.

At present, the mainstream device interconnection protocol in the local area network is Zero configuration networking (Zeroconf) protocol, and the goal is to enable users to easily connect various network devices, such as computers and printers.

Detailed ways

The present disclosure will be further described below in conjunction with the accompanying drawings and embodiments. The embodiments described herein are merely illustrative of the disclosure and are not intended to limit the invention. For the convenience of description, only some but not all of the structures related to the present disclosure are shown in the drawings.

Embodiment 1

FIG. 1 is a flowchart of a method for communication of a terminal according to Embodiment 1 of the present disclosure. The method may be implemented by a device for communication by a terminal, and the device may be implemented by software and/or hardware, and the device may be integrated in an electronic device. In the device, the electronic device may include a television, a smart phone, a tablet, a printer, and the like. The method in this embodiment can be applied to a sending terminal, and the sending terminal can be any one of the terminals accessed in the local area network. Referring to FIG. 1, the method of this embodiment includes:

S110. The device sends a packet to the receiving terminal by using a router according to the zero-configuration network service protocol, where the preset packet sending manner includes a broadcast mode.

Among them, the zero-configuration network service protocol is a network technology for automatically generating an available Internet Protocol (IP) address, without requiring additional manual configuration and a dedicated configuration server. Based on the zero-configuration network service protocol, devices connected to the local area network transmit packets in the multicast mode based on the multicast domain name system (MDNS) protocol.

However, because many routers are not compatible with the forwarding of multicast packets, the receiving terminal cannot obtain the multicast packets sent by the sending terminal, which affects the mutual discovery between the terminals. Therefore, in order to improve the success rate of mutual discovery between different terminals, the preset packet sending manner provided in this embodiment further includes a broadcast mode. As all the routers can forward the broadcast packets, the routers cannot forward the multicast packets because the routers cannot forward the packets based on the multicast mode of the traditional zero-configuration network service protocol. , resulting in problems that cannot be discovered by different devices.

The technical solution provided in this embodiment is an improvement on the traditional zero-configuration network service protocol, and any terminal (including the transmitting terminal and the receiving terminal) in the access LAN does not need to install the corresponding client software, and does not need to add new broadcasts and groups. The transmission protocol of the broadcast message. As long as any terminal accesses the local area network and the terminal is in normal working condition, the improved zero-configuration network service protocol can be started, and different terminals can discover each other, thereby establishing a communication connection with each other.

In an embodiment, since the zero-configuration network service protocol is a service protocol provided by Apple, the embodiment of the present disclosure may also apply the same to the Android system, that is, in addition to the mobile operating system (iPhone Operating System, which is installed by Apple). The device provided by the IOS can enjoy the service provided by the protocol, and the device installed with the Android system can also recognize and interact with each other by using the technical solutions provided by the embodiments of the present disclosure.

Exemplarily, in this embodiment, the message sent by the sending terminal may include a service type of the sending terminal (such as a print service or a television service, etc.), an Internet Protocol Address (IP address), or a service port number. The message may be sent by using a User Datagram Protocol (UDP) packet. After receiving the packet of the sending terminal, the receiving terminal feeds back the attribute information of the sending terminal itself to establish a communication connection with the sending terminal.

S120. When obtaining the response information to the packet sent by the receiving terminal, storing the attribute information of the receiving terminal in the response information, and establishing a communication connection with the receiving terminal according to the attribute information of the receiving terminal.

The receiving terminal may be all terminals except the transmitting terminal in the local area network, and any terminal newly accessing the local area network may also serve as the receiving terminal. The attribute information of the receiving terminal includes the service type, IP address, and service port number of the receiving terminal.

Exemplarily, when the sending terminal acquires the response information of the packet sent by the receiving terminal, the attribute information of the different receiving terminal may be stored in the service list. In the service list, information such as the service name and service type of different receiving terminals can be displayed. When a device is newly connected to the local area network, if the message sent by the sending terminal is obtained, the sending terminal can feed back the newly accessed device by feeding back the response message to the sending terminal.

In an embodiment, after the transmitting terminal stores the attribute information of the receiving terminal, the user can see a plurality of receiving terminals that have accessed the local area network in the service list of the sending terminal, so that service sharing between the plurality of terminal devices can be implemented. For the shared service, the user can choose according to the actual needs. For example, if the sending terminal is a mobile phone, and the receiving terminal is a printer, a television, a tablet, and the like, there will be a printer, a television, and a service list in the mobile phone. The identity of the terminal such as a tablet. When the user clicks on the identifier corresponding to the printer, the mobile phone held by the user can establish a communication connection with the printer, and by performing operations on the mobile phone, the file to be printed in the mobile phone can be printed through the printer.

Exemplarily, since the attribute information of the receiving terminal has been stored in the service list by the sending terminal, the transmitting terminal can perform one-to-one access by receiving the IP address in the attribute information of the terminal when accessing or controlling the receiving terminal. Or control.

The technical solution of the embodiment improves the zero-configuration network service protocol, and the broadcast mode is added as one of the preset message sending modes on the basis that the default packet sending mode is multicast. Since all routers are compatible with the forwarding of broadcast packets, the packets are sent to the receiving terminal according to the preset packet sending manner, which solves the problem that different terminals cannot be mutually discovered due to poor compatibility of the router in the related art. problem. When the response information of the packet sent by the receiving terminal is obtained, the attribute information of the receiving terminal is stored in the response information, and the transmitting terminal can identify all receiving terminals accessed in the local area network by using the attribute information of the receiving terminal, and can The attribute information establishes a communication connection with all receiving terminals, thereby laying a foundation for realizing mutual control between multiple terminals.

Embodiment 2

2 is a flowchart of a method for communication of a terminal according to Embodiment 2 of the present disclosure. This embodiment is optimized on the basis of the foregoing embodiment, and based on the broadcast mode, a message is sent according to the multicast mode. The explanation of the same or corresponding terms as in the above embodiments will not be repeated herein. Referring to FIG. 2, the method for providing terminal communication in this embodiment includes:

S210, based on the zero-configuration network service protocol, in the case that the primary router supports the forwarding of the multicast packet, the multicast message corresponding to the multicast mode is forwarded to the primary router level by the primary router according to the multicast mode and the broadcast mode. Each secondary router of the connection, and the broadcast message corresponding to the broadcast mode is forwarded by the primary router to at least one secondary router cascading with the primary router, wherein each secondary router is set to at least one of the following The item is sent to the receiving terminal that has a communication connection with the secondary router: a multicast message and a broadcast message.

Exemplarily, the preset message sending manner in the embodiment of the present disclosure includes a default multicast mode based on the zero-configuration network service protocol in addition to the broadcast mode.

Among them, the broadcast mode is adopted, although the message can be transmitted at one time, but the message cannot be transmitted to all target nodes once. For example, in the case where there is a cascade router in the home, if there are two secondary routers B and R below the primary router A, and only the broadcast mode is used to send the message, there can be only one router in the router B and the router C. Received a broadcast message.

However, in the case that the router supports the forwarding of multicast packets, the multicast mode can be used to transmit the packets to all the destination nodes at a time. For example, the multicast packets can be forwarded to the router B and the router C through the router A.

In summary, the packet can be sent in the multicast mode or in the broadcast mode. When the router does not support the forwarding of the multicast packet, the broadcast packet can be forwarded to the receiving terminal to ensure that the device discovery in the LAN is not affected. When the router supports the forwarding of multicast packets, the multicast packets can be sent to all receiving terminals to ensure the comprehensiveness of device discovery.

For example, if the packet is sent in the multicast mode and the broadcast mode, the multicast message and the broadcast message include the attribute information of the sending terminal, and the attribute information of the sending terminal includes the service type of the sending terminal and the sending. The Internet Protocol address of the terminal and the service port number of the sending terminal.

In an embodiment, when the broadcast packet and the multicast packet are respectively sent according to the broadcast mode and the multicast mode, the multicast packet may be sent first, and if the receiving terminal is not received within a set time (for example, 30 seconds) The response message to the multicast packet indicates that the router does not support the forwarding of multicast packets or that there is no receiving terminal other than the current transmitting terminal in the local area network. At this time, the current transmitting terminal sends the broadcast message according to the broadcast mode. If the response information of the other terminal to the broadcast message is received within the set time (for example, 10 seconds), the receiving terminal has a multicast terminal in the local area network. The response message was not received after the packet was sent because the router does not support the forwarding of multicast packets. By adopting the above method, it can be verified whether the router is compatible with the transmission of multicast packets.

In an embodiment, in order to save the response time of the receiving terminal and improve the user experience, the method of simultaneously transmitting the multicast packet and the broadcast packet in the embodiment may be sent in sequence (for example, the interval is not more than 5). second). When the response information of the receiving terminal is acquired at a set time (for example, 10 seconds), it is explained that other terminal devices exist in the local area network in addition to the current transmitting terminal. On the other hand, if the response information of the receiving terminal is not acquired within the set time (for example, 10 seconds), it means that there is no terminal device other than the current transmitting terminal in the local area network. Therefore, when the multicast packet and the broadcast packet are simultaneously transmitted or sequentially sent, the time used by the former is relatively long compared to the manner in which the multicast packet and the broadcast packet are not continuously transmitted (for example, 30 seconds). Short, you can quickly discover all the terminal devices connected to the LAN, so that it is easy to establish communication connections between different terminals, which is convenient for user control.

In an embodiment, in order to enable devices to discover each other more quickly, the sending frequency of the message may be increased, for example, according to a set period (for example, 5 seconds), and according to a preset packet sending manner, the router may The receiving terminal sends a packet to prevent the receiving terminal from acquiring the packet when it is in the non-working mode.

In an embodiment, for a mobile device, such as a mobile phone or a tablet computer, in consideration of saving power, the wireless Fidelity (WiFi) network of the device is configured into a power saving mode without the user operating. . At this time, if a sending terminal sends a multicast packet or a broadcast packet, the device in the power saving mode does not answer the packet of the sending terminal, which may cause some mobile devices to be undetected by other devices for a long time. Therefore, in this embodiment, a packet of 5 seconds is used, and a multicast packet and a broadcast packet are simultaneously sent every 5 seconds. The advantage of the setting is that the device waking up from the non-working mode can immediately receive the report of the sender. The message is replied to the transmitting terminal to identify the existence of the device, which lays a foundation for realizing mutual control between the transmitting terminal and the device.

S220. When obtaining the response information to the packet sent by the receiving terminal, storing the attribute information of the receiving terminal in the response information, and establishing a communication connection with the receiving terminal according to the attribute information of the receiving terminal.

On the basis of the foregoing embodiment, the present embodiment increases the success rate of device discovery by using the method of cyclically transmitting packets in a set period. In addition, the method of transmitting multicast packets and broadcast packets simultaneously or sequentially, not only solves the problem that the routers cannot communicate with multicast packets when the compatibility of the routers is poor, but also avoids the use of cascading when using broadcast packets. Only some mobile terminals in the LAN caused by multiple routers can receive packets. When the router is compatible with the forwarding of multicast packets, if there are multiple routers, all receiving terminals can receive multicast packets from the sending terminal, thus ensuring the comprehensiveness of the shared services.
