Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

The embodiment of the application provides a communication method and device. Referring to fig. 1, fig. 1 is a schematic structural diagram of a communication system according to an embodiment of the present application, and the communication method is applicable to the communication system. As shown in fig. 1, the communication system mainly includes a first network device and a second network device. The first network device and the second network device may be the same type of network device. For example, the first network device and the second network device may be an optical network terminal (optical network termination, ONT), an optical network unit (optical network unit, ONU), or the like, which is not limited herein. For ease of understanding, in the embodiments of the present application, a first network device and a second network device will be described. The second network device and the first network device can be connected in a wired or wireless mode. For example, any local area network (local area network, LAN) port on the second network device may be connected to any LAN port on the first network device through a network cable, or the second network device and the first network device may be connected through a wireless LAN port, which is not limited herein. Wherein the second network device may also be connected to a plurality of network devices other than the first network device. Wherein the plurality of network devices and the first network device are the same type of network device. In specific implementation, the working states of the access network interface and the local area network interface of the first network device are judged. If the access network interface is in a non-working state and the local area network interface is in a working state, a host configuration discovery message is sent through the local area network interface. If a response message sent by the second network device for the host configuration discovery message is received through the local area network interface within a preset time period, determining the working mode of the first network device based on the response message. And if the working mode of the first network equipment is the first working mode, acquiring WiFi configuration information of the wireless local area network from the second network equipment.

In general, in order to expand the coverage of WiFi signals, a manner of connecting a third party device to an optical network terminal may be used to expand the coverage of WiFi signals, but this manner increases additional third party devices on one hand, and requires manual configuration of parameters of the third party devices on the other hand, which has high technical requirements on users, and has low efficiency when manually configuring the working modes of the devices, and reduces user experience.

The technical problems to be solved by the communication method provided by the embodiment of the application are as follows: how to efficiently set the operation mode of the network device to improve the user experience.

Referring to fig. 2, fig. 2 is a flow chart of a communication method according to an embodiment of the present application. As shown in fig. 2, the above communication method may include the steps of:

s201, the first network device judges the working states of an access network interface and a local area network interface of the first network device.

In some possible embodiments, the first network device may determine/query the operating states of its own access network interface and lan interface. The access network interface is an interface between an external network (i.e. a wide area network) and an internal network (i.e. a local area network), and the local area network interface is an interface between the internal networks. Specifically, the access network interface may be a passive optical network (passive optical network, PON) port, and the local area network interface may be a LAN port or a wireless LAN port. The operating states of the access network interface or the lan interface may include an operating state (i.e., UP state) and a non-operating state (i.e., DOWN state), among others.

S202, if the access network interface is in a non-working state and the local area network interface is in a working state, the first network equipment generates a host configuration discovery message.

In some possible embodiments, when the access network interface of the first network device is in a non-working state and the lan interface is in a working state, the first network device may generate the host configuration discovery message. The host configuration discovery message may be a dynamic host configuration protocol discovery (dynamic host configuration protocol discover, DHCP discover) message. The DHCP discover message may include a section of character string, i.e., a random number, randomly generated by the first network device.

S203, the first network device sends a host configuration discovery message through the local area network interface.

In some possible embodiments, the first network device may broadcast the host configuration discovery message via a lan interface.

S204, the first network equipment receives the response message.

In some possible embodiments, the first network device may receive a response message sent by the second network device. The response message may be a dynamic host configuration protocol response (dynamic host configuration protocol offer, DHCP offer) message. The DHCP offer message may include a random number, and an internet protocol (internet protocol, IP) address, i.e., a first internet protocol address, assigned by the second network device to the first network device.

Generally, if the random number included in the response message is the same as the random number included in the host configuration discovery message, it may be determined that the response message is the response message of the host configuration discovery message. That is, when the random number included in the response message is the same as the random number included in the host configuration discovery message, it may be determined that the response message and the host configuration discovery message belong to the same session. Wherein the random number is randomly generated and recorded by the first network device. For easy understanding, the embodiment of the present application uses a DHCP discover message as a host configuration discovery message and a DHCP offer message as a response message for illustration.

For example, referring to fig. 3, fig. 3 is a schematic diagram of formats of a DHCP discover message and a DHCP offer message according to an embodiment of the present application. As shown in fig. 3, the basic formats of the DHCP discover message and the DHCP offer message are the same, except that some field values in the messages are different. Specifically, the meaning of each field in the DHCP packet is as follows: op, message type, wherein 1 represents request message and 2 represents response message. htype, hardware address type, where 1 denotes the hardware address of an ethernet of 10 Mb/s. hlen, hardware address length. hop count, i.e. the number of relays traversed by DHCP messages. xid, transaction ID, a random number selected by the client, is used by the server and the client to communicate requests and responses between them, which the client uses to match requests and responses. The ID is set by the client and returned by the server as a 32-bit integer. secs, filled in by the client, represents the number of seconds that have elapsed since the client began to obtain the IP address or the IP address was renewed. flags, flag field. Bit 0 is 0, indicating unicast, and bit 1 indicates broadcast. The IP address of the client is shown as 0 in both DHCP discover and DHCP offer messages. The yiaddr, the IP address assigned to the client by the server, is specifically shown in the DHCP offer message sent by the server, and is shown as 0 in the DHCP discover message. siaddr, indicates the IP address of the server to be used in the next phase of the DHCP protocol flow. The IP address of the DHCP relay. chaddr, hardware address of client. A sname, an optional server hostname. file, the server designates the name of the starting configuration file and the path information for the client, and the file is specifically displayed only in the DHCP Offer message, and is displayed as empty in the DHCP discover message. Options, optional, format "code+length+data". Wherein the server is the second network device, the client is the first network device, the xid value indicated by the xid field is the random number, and the IP address indicated by the yiaddr address is the first internet protocol address.

S205, if the first network device receives a response message sent by the second network device for the host configuration discovery message through the local area network interface within a preset time period, determining the working mode of the first network device based on the response message.

In some possible embodiments, if the first network device receives, through the lan interface, a response message sent by the second network device for the host configuration discovery message within a preset period of time, the first network device may determine the working mode of the first network device based on the response message. That is, after the first network device sends the host configuration discovery message through the lan interface, timing may be started, and if a response message sent by the second network device for the host configuration discovery message is received through the lan interface within a preset period of time, the first network device may determine the working mode of the first network device based on the response message. Here, the preset time period may be 3 seconds, specifically determined according to an actual application scenario, which is not limited herein. Specifically, if the first ip address is within the preset ip address range, the operation mode of the first network device may be determined to be the first operation mode. If the first ip address is not within the preset ip address range, it may be determined that the working mode of the first network device is an AP routing mode. The first operation mode may be an Access Point (AP) bridge mode. The AP bridge mode may be understood as a product form of the first network device is an AP form, that is, the first network device corresponds to an AP, and the first network device operates in the bridge mode. The above AP routing mode may be understood as a product form of the first network device being an AP form, i.e. the first network device is an AP, and the first network device operates in the routing mode. The preset internet protocol address range is an internet protocol address range defined based on RFC1918 private network address allocation (RFC 1918 address allocation for private internets) protocol.

In a specific implementation, the connection relationship between the second network device and the first network device may be that the lan interface on the first network device is connected to the lan interface of the second network device through a network cable. Therefore, the second network device may receive, through the lan interface on the second network device, the host configuration discovery message sent by the first network device through the lan interface on the first network device. Here, the second network device may send a response message for the host configuration discovery message to the first network device according to the working mode of the second network device by determining the working mode of the second network device. The response message is used for determining a working mode of the first network device.

If the working mode of the second network device is the second working mode, the first internet protocol address included in the response message is an IP address allocated by the second network device to the first network device, and the first internet protocol address is within a preset internet protocol address range. The second working mode may be an ONT mode, and the preset internet protocol address range is an internet protocol address range defined based on a private network communication RFC1918 protocol. It should be appreciated that the second network device is equivalent to a gateway when the operating mode of the second network device is the ONT mode. Since the gateway itself supports the DHCP protocol, the second network device may assign a private network IP address to the first network device connected to the lan interface according to RFC1918 protocol. That is, when the second network device is operating in the ONT mode, the first network device will be assigned a first internet protocol address by the second network device, and the assigned first internet protocol address is a private network IP address. If the second network device is in the AP bridge mode, the second network device will not support the DHCP protocol. Therefore, the second network device can forward or pass through the host configuration discovery message sent by the first network device to the third network device, so that the third network device allocates the first internet protocol address for the first network device. The third network device may be an upper network device of the second network device, and the third network device supports a DHCP protocol. It will be appreciated that the first internet protocol address assigned by the third network device to the first network device is a public network IP address. Therefore, when the second network device receives the response message sent by the third network device and including the first internet protocol address allocated by the third network device to the first network device, the second network device may forward the response message of the third network device to the first network device for the host configuration discovery message, so that the first network device may determine the working mode of the first network device according to the received response message.

Specifically, after the first network device receives the response message sent by the second network device, the first network device may determine the working mode of the first network device according to the first internet protocol address included in the received response message. Specifically, if the first ip address included in the response message is within the preset ip address range, it may be determined that the product form of the second network device is an ONT form, that is, the second network device corresponds to the gateway, and the product form of the first network device is an AP form, that is, the first network device corresponds to the AP. If the first internet protocol address is not within the preset internet protocol address range, the product form of the second network device is determined to be an AP form, i.e. the second network device corresponds to the AP, and the product form of the first network device is an AP form, i.e. the first network device also corresponds to the AP. When the product form of the second network device is an ONT form and the product form of the first network device is an AP form, the working mode of the first network device is a bridge mode, that is, the AP bridge mode.

Alternatively, in some possible embodiments, the operation mode of the first network device may be determined to be the ONT mode when the access network interface of the first network device is in an operating state (i.e., UP state) or the lan interface is in a non-operating state (i.e., DOWN state).

Optionally, in some possible embodiments, if a response message sent by the second network device for the host configuration discovery message is not received through the lan interface within a preset period of time, it may be determined that the working mode of the first network device is an ONT mode.

Optionally, in some possible embodiments, when the random number included in the response packet is different from the random number included in the host configuration discovery packet, it may also be determined that the operation mode of the first network device is an ONT mode.

Optionally, in some possible embodiments, the operation mode of the first network device may be set to an AP bridge mode based on a manual setting manner.

S206, if the working mode of the first network device is the first working mode, the first network device generates a WiFi configuration information acquisition request.

In some possible embodiments, if the operation mode of the first network device is the first operation mode, the first network device may generate the WiFi configuration information acquisition request. The WiFi configuration information acquiring request is used for requesting to acquire WiFi configuration information. The WiFi configuration information may include a WiFi user name, a WiFi password, and the like, which are not limited herein.

S207, the first network device sends a WiFi configuration information acquisition request.

In some possible implementations, both the first network device and the second network device may support a communication protocol for WiFi configuration. For example, the communication protocol may be an easy-mesh protocol or an xlink protocol, and the like, which is not limited herein. After the first network device generates the WiFi configuration information obtaining request, the first network device may send the WiFi configuration information obtaining request to the second network device according to the corresponding communication protocol.

S208, the first network device receives WiFi configuration information response information.

In some possible embodiments, the first network device may obtain the WiFi configuration information carried in the WiFi configuration information response information by receiving the WiFi configuration information response information generated by the second network device based on the WiFi configuration information obtaining request, and analyzing the WiFi configuration information response information. The WiFi configuration information may include a WiFi user name, a WiFi password, and the like, which are not limited herein.

In the embodiment of the application, the working states of the access network interface and the local area network interface of the first network device are judged. If the access network interface is in a non-working state and the local area network interface is in a working state, the host configuration discovery message can be sent through the local area network interface. If a response message sent by the second network device for the host configuration discovery message is received through the local area network interface within a preset time period, the working mode of the first network device can be determined based on the response message. If the working mode of the first network device is the first working mode, the first network device may obtain the WiFi configuration information of the wireless local area network from the second network device. By adopting the embodiment of the application, the problems of low efficiency, high complexity and the like existing in the process of manually configuring the working mode of the third-party equipment can be solved, the configuration efficiency is improved, and the user experience is improved.

The baseband processor may also be expressed as a baseband processing circuit or a baseband processing chip. The above-mentioned central processing unit may also be expressed as a central processing circuit or a central processing chip. The function of processing the communication protocol and the communication data may be built in the processor, or may be stored in the storage unit in the form of a software program, which is executed by the processor to realize the baseband processing function.

In the embodiment of the present application, the antenna and the radio frequency circuit with the transceiver function may be regarded as a transceiver unit of the apparatus, and the processor with the processing function may be regarded as a processing unit of the apparatus.
