However, the number of router connections is limited, and the number of devices that can use relays is limited, and with the increase in devices such as smart home appliances and handheld terminals, newly added devices cannot be connected to relays and cannot use wireless signals.

In order to use the Wi-Fi module, the mobile terminal generally sets the number of antennas to receive and transmit data.

If a large number of antennas are provided, a high Wi-Fi performance is maintained, which may cause waste of antenna resources and power in many cases.

In addition, the high-power Wi-Fi signals have certain electromagnetic radiation on human bodies and cause damage to the human bodies.

Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.

Referring to fig. 1, a flowchart illustrating steps of an antenna setting method for relay communication according to an embodiment of the present invention is shown, and specifically may include the following steps:

and 101, detecting a relay level of the relay node when the station node of the Wi-Fi module is connected with a router or a relay node at the upper stage.

In a specific implementation, the embodiments of the present invention may be applied to a mobile terminal, for example, a mobile phone, a tablet computer, a smart wearable device (such as a smart watch), and the like.

These mobile terminals may be installed with Windows phone, Android, IOS, Windows, and other operating systems, configured with a Wi-Fi (WIreless-Fidelity) module, and may be connected to a WIreless node as a relay node to forward a WIreless signal.

A Wi-Fi module is also called a serial port Wi-Fi module, belongs to an Internet of things Transmission layer, can convert a serial port or TTL (transistor-transistor logic level) signal into an embedded module which accords with a Wi-Fi wireless network communication standard, and is internally provided with a wireless network Protocol IEEE802.11b.g.n Protocol stack and a TCP/IP (Transmission Control Protocol/Internet Protocol) Protocol stack.

In a particular implementation, Wi-Fi modules typically have three functions: station, softAP, P2P.

Wherein station: which means devices connected to a wireless network, can communicate with other devices inside or outside the wireless network through an AP (wireless access point).

softAP: the function of using the application to realize the AP is shown, so that the mobile terminal can be used as a route to link other stations.

P2P (Peer-to-Peer): also known as Wi-Fi Direct, can support two Wi-Fi devices to connect directly and communicate without an AP.

In the embodiment of the present invention, the mobile terminal may be used as a relay node to connect to a higher-level device, which may be a router or a relay node, that is, the relay node may be hooked after the relay node to form a tree-like relay network.

If the mobile terminal is a relay node of the first level, the mobile terminal can be connected with a router of the first level through a station node of the Wi-Fi module.

If the mobile terminal is a second-level relay node or a relay node below the second level, the mobile terminal can be connected with a first-level relay node through a station node of the Wi-Fi module.

In one embodiment, a getWifiState () method in a WifiManager can be called to detect whether the mobile terminal turns on a station node of Wi-Fi.

When the state node is detected to be started, whether the state node is connected with the wireless node or not can be detected by calling an Application Programming Interface (API) Interface getNetworkInfo () provided by the connectivity manager, and using the connectivity manager.

If the returned NetworkInfo object is not null and isConnected () is true, the wireless node is confirmed to be connected.

When the situation node is detected not to be started or not to be connected with the wireless node, prompt information of the connected wireless node is generated, such as 'please turn on the Wi-Fi and connect a router or a relay'.

If the mobile terminal is accessed to the network as the relay node, the relay level where the mobile terminal is currently located can be identified.

The relay node of the first stage may be referred to as a root node, and two stages of relay nodes are connected with each other, where the relay node of the previous stage is a parent node of the relay node of the next stage, and relatively speaking, the relay node of the next stage is a child node of the relay node of the previous stage.

In one embodiment, each level of relay node may maintain one relay configuration information, in which information such as routing path, relay level, login information (such as service set identification SSID and password) and the like may be recorded.

In this embodiment, the relay level at which the relay node is located may be set as the first level.

And according to a preset specification, requesting relay configuration information to a router or a relay node at the upper stage.

If the device at the upper level is a router, and the router does not set the specification, the request of the mobile terminal is ignored.

And if the equipment at the upper level is the relay node which has set the standard, responding to the request of the mobile terminal and returning the relay configuration information.

And when the request is successful, extracting the relay level of the relay node at the upper stage from the relay configuration information.

And on the basis of the relay level of the relay node at the upper stage, calculating the relay level where the relay node is located to replace the first stage.

Further, the mobile terminal may add one to the relay level of the relay node at the previous stage, so as to obtain the relay level at which the mobile terminal is currently used as the relay node.

For example, if the relay level of the relay node at the previous stage is the second stage, the relay level of the mobile terminal as the relay node is the third stage, and the default first stage is modified to the third stage.

When the request fails, the relay level as the relay node is determined to be the first level. Of course, the above-mentioned detection method of the relay level is only an example, and when implementing the embodiment of the present invention, other detection methods of the relay level may be set according to actual situations, for example, requesting the relay level to the router or the relay node at the previous stage, if the request fails, setting the relay level as the first stage, if the request succeeds, calculating the current relay level on the basis of the relay level of the relay node at the previous stage, and the like, which is not limited in this embodiment of the present invention. In addition, besides the above relay level detection method, a person skilled in the art may also adopt other relay level detection methods according to actual needs, and the embodiment of the present invention is not limited to this.

And 102, starting the softAP node of the Wi-Fi module according to the relay level and configuring relay communication parameters so as to connect the application terminal and/or the relay node of the next level.

If the station node of the Wi-Fi module of the mobile terminal is connected to the router or the relay node of the previous stage, a relay instruction can be sent to the Wi-Fi module according to the relay level, the softAP node is started, and the application terminal and/or the relay node of the next stage are/is connected through the softAP node.

Wherein, the application terminal may refer to a terminal that realizes its own function, for example, an intelligent electric rice cooker, an intelligent air conditioner, an intelligent water heater, and the like.

It should be noted that the mobile terminal may be used as a relay node, and may also be used as an application terminal to implement functions such as browsing a web page, playing a game, and playing a network video.

In one embodiment of the invention, a channel of the softAP node can be determined, which generally has no interference with the router and other relay nodes, and therefore, the relay instruction can be issued on the channel.

In a specific implementation, the frequencies corresponding to different channels are:

and when the relay level is the first level, receiving login information input by a user, wherein the login information comprises a service set identifier and a password.

In this case, the User may be prompted at a UI (User Interface) to enter the SSID and password of the relay (i.e., mobile terminal).

And if the user inputs the SSID and the password in the UI, using the SSID and the password, and otherwise, using a default SSID and a default password.

When the relay level is the second level or more, the login information is extracted from the relay configuration information of the relay node at the upper level, the login information between the father node and the son node is kept the same, and under the condition that the invalid network signal is poor (such as less than-90 DB), roaming can be started, and other adjacent relay nodes are automatically connected by adopting the same login information.

If the login information is obtained, the softAP node of the Wi-Fi module can be started according to the channel, the service set identification and the password so as to broadcast the service set identification.

In a specific implementation, freq (channel), SSID, and password are written into a hostapd.

hostapd-d hostapd.conf

The freq, SSID and password can be validated.

After the relay instruction is sent, the broadcast frame sent by the relay node (i.e. the mobile terminal) carries the SSID, and after the SSID is scanned, other terminals can use the SSID and the password for connection.

In a specific implementation, the relay node (i.e., the mobile terminal) may be regarded as an AP, which periodically broadcasts a Beacon frame, and the SSID of the relay node (i.e., the mobile terminal) can be obtained by scanning the Beacon frame by other station devices.

When an application request sent by one or more electronic devices (application terminals and/or relay nodes at the next stage) for the SSID is received, a response message challenge text is returned to the one or more electronic devices.

When a connection request sent by one or more electronic devices is received, whether the password in the connection request is the same as a preset password or not is verified, and if yes, the one or more electronic devices are accessed.

In the embodiment of the invention, the relay nodes of different relay levels have different relay communication parameters, so that the station node and the softAP node can communicate with each other, and the softAP node is connected with the next-level application terminal and/or relay node due to the fact that the station node is connected with the first-level wireless node, so that the previous-level router or relay node can communicate with the next-level application terminal and/or relay node, and the relay function is realized.

In one embodiment of the present invention, step 102 may include the following sub-steps:

and a sub-step S11 of turning on the packet forwarding function.

In a specific implementation, a packet forwarding function may be started through an echo attribute value to support forwarding of a data packet between a station node and a softAP node:

echo 1>/proc/sys/net/ipv4/ip_forward

packet forwarding is the process of allowing packets to be forwarded from one terminal to another.

In the embodiment of the invention, a packet forwarding function is opened, and the data packet is supported to be mutually forwarded between the station node and the softAP node.

And a substep S12, when the relay level is the first level, setting the configuration information of the address translation function NAT.

In practical application, the configuration information of an Address translation function NAT (network Address translation) can be called to the Wi-Fi module through the system Address table service iptables, and the NAT can automatically modify the source IP Address and the destination IP Address of the IP packet to disguise the IP Address of the application terminal.

Of course, prior routing tables may also be purged before sending the routing tables and NAT.

The configuration information of the Iptables and NAT configuration is as follows:

# remove old rules (clear previous routing tables)

iptables-F

iptables-t filter-F

iptables-t nat-F

#Bring up NAT rules

iptables-t nat-A POSTROUTING-s 192.168.49.0/24-d 0.0.0.0/0-j MASQUERADE

Wherein, assuming that the IP segment of the relay (i.e. the mobile terminal) is 192.168.49.0, the sending Bring up NAT rules can repackage and unpack the data packet with 192.168.49.0/24 network segment as the source address, and disguise as the source address of 0.0.0.0/0.

And a substep S13, when the relay level is the second level or below, allocating an IP address from the relay node of the previous level, and establishing a routing path between the relay nodes of each level.

In a specific implementation, an IP address may be dynamically assigned to a relay node at or below the second level.

In one embodiment, the total address space may be divided into multiple segments or multiple sub-domains, each relay node may continue to allocate its assigned address to a sub-node from which the application terminal does not have a sub-node, so no address needs to be allocated.

The mobile terminal as a relay node has an address pool, i.e. a set of addresses, the address pool capacity of a relay node at or below the second level is determined from its parent node, which calculates the address pool capacity by the following formula:

C_skip(d)＝1+C_m×(L_m-d-1) R_m＝1

C_skip(d)＝(1+C_m-R_m-C_m×R_m ^Lm-d-1)/(1-R_m) R_m≠1

wherein, C_skip(d) An offset value indicating that a parent node having a relay level d determines when assigning an address, an address pool capacity of a corresponding child node, C_mIndicating the maximum number of subnodes, L, that the relay node can receive_mRepresenting the maximum depth of the network (relay level), R_mRepresents the maximum number of subnodes that the relay node can receive, and d represents the node depth (relay level).

The depth d of a father node is increased by 1 when the network is accessed, the depth of a coordinator is defined as 0, C_m、L_m、R_mThese three parameters may be provided by the user describing the size and general form of the network.

Calculating the offset C_skip(d) And then, the father node determines the network address according to the type of the network-accessing child node.

If the child node is a relay node, the address can be calculated by adopting the following formula:

A_n＝A_p+C_skip(d)×(n-1)+1 1≤n≤R_m

wherein A is_pIs the network address of a father node, n is the node applying for network access and is the second child relay node, A_nAnd obtaining the network address for the nth network access sub-relay node.

In the embodiment of the present invention, a relay routing table may be maintained in each relay node, and in the relay routing table, when each relay node enters the network, its assigned address and a parent-child relationship between the relay node and other relay nodes may be recorded, and when each relay node exits the network, its assigned address is deleted, so that the parent-child relationship and addresses between relays at each level may constitute a routing path of relays at each level.

And a substep S14 of inquiring the IP address of the router or the relay node of the previous stage.

Substep S15, setting the IP address of the router or the relay node at the upper stage as the gateway address of the domain name system DNS

In the embodiment of the invention, on one hand, an address table service iptable in the system can be called to send a gateway address of a DNS (Transmission Control Protocol) based on a TCP (Transmission Control Protocol) to a Wi-Fi module;

the command format is:

iptables-tnat-I PREROUTING-I (Relay device name) -p tcp-dport 53-j DNAT-to-destination (gateway)

On the other hand, the address table service iptable in the System can be called, and a gateway address of the DNS based on UDP (Open System Interconnection) is sent to the Wi-Fi module.

The command format is:

iptables-tnat-I PREROUTING-I (Relay device name) -p udp-dport 53-j DNAT-to-destination (gateway)

When the relay node of which the relay level is the first level, the gateway address of the domain name system DNS is set as the gateway address of the router.

When the relay level is the second level or a relay node below the second level, the gateway address of the domain name system DNS is set as the IP address of the relay node at the upper level.

As described above, the DNS gateway addresses of TCP and UDP are added to the relay device (i.e., the mobile terminal), and after the DNS is configured, the input uniform resource locator URL is transferred step by step and is finally resolved by the DNS server, thereby implementing network communication.

And 103, determining the communication type of the communication between the router or the relay node at the upper level and the application terminal and/or the relay node at the lower level.

In a specific implementation, the protocol type of the data packet transmitted between the router or the relay node at the previous stage and the application terminal and/or the relay node at the next stage may be counted.

Further, the packet headers of all data packets accessing the internet through Wi-Fi can be analyzed, the data packets are counted in real time, the proportion of each protocol is counted, and then the proportion is reported to determine the communication type.

The Protocol includes FTP (File Transfer Protocol), RTP (Real-time Transport Protocol), WAP (Wireless Application Protocol), HTTP (Hypertext Transfer Protocol), and the like.

Taking the FTP protocol as an example, the statistical method for processing the data packet header is as follows:

as shown in fig. 2, in the data header format of FTP, the first 12 bytes of a first row are a destination hardware address and a source address in a header of a protocol MAC (media Access Control) frame.

The next two bytes are a type field in the MAC frame header identifying what type of protocol was received from the upper layer and "0806" indicates that an FTP type datagram was received from the upper layer.

The following data represents the contents of the datagram:

"0001" indicates that the hardware type is Ethernet

"0800" indicates that the type of protocol used is IP type

"0604" indicates a hardware address length of 6 bytes and a protocol address length of 4 bytes, respectively

"0001" indicates that the ARP request operation is performed

"0013 d4ae 4426" and "3 b 4f 129 b" indicate the source hardware address, source protocol address (59.79.18.155)

"000000000000", "3 b 4f 12 fe" indicates the destination hardware address and the destination protocol address (59.79.18.254)

The remaining 0 s are padding data.

In summary, the data packet is a request message of the FTP protocol.

And 104, adjusting the number of the transmitting antennas and the receiving antennas according to the communication type.

In the embodiment of the invention, the mobile terminal is provided with at least two Wi-Fi antennas, the Wi-Fi antennas are used for transmitting Wi-Fi data or receiving Wi-Fi data, the Wi-Fi antennas used for transmitting the Wi-Fi data are transmitting antennas, and the Wi-Fi antennas used for receiving the Wi-Fi data are receiving antennas.

In specific implementation, the number of receiving antennas and the number of transmitting antennas may be dynamically adjusted according to the communication type of communication between the router or the relay node at the previous stage and the application terminal and/or the relay node at the next stage, and power consumption may be adaptively adjusted in the process of relay communication.

In an embodiment of the present invention, to reduce system resource consumption, it may be determined whether a traffic volume communicated between the router or the relay node at the previous stage and the application terminal and/or the relay node at the next stage is greater than a preset traffic volume threshold (e.g., 20 KB/s).

If yes, the flow is larger, and the number of the transmitting antennas and the number of the receiving antennas can be adjusted by adopting the communication type.

If not, indicating that the traffic is low, the number of transmit antennas and receive antennas may be set to a second number (e.g., 1) to reduce power consumption.

In one scenario, when the communication type is a first type, the number of receive antennas is set to a first number and the number of transmit antennas is set to a first number.

Wherein the first number is greater than or equal to a preset first number threshold, e.g., 2.

In this scenario, the first type includes a download type or an upload type, and when high-speed uploading or downloading such as FTP is used, 2 (the first number) transmitting antennas and receiving antennas of the relay node are all used to form multiple spatial data streams, and the multiple spatial data streams are forwarded at full speed.

In another scenario, when the communication type is the second type, it is determined whether the downloaded traffic is greater than a preset download threshold.

If yes, the number of the receiving antennas is set to be the first number, and the number of the transmitting antennas is set to be the second number.

If not, the number of the receiving antennas is set to be the second number, and the number of the transmitting antennas is set to be the second number

Wherein the first number is greater than or equal to a preset first number threshold (e.g., 2), the second number is less than or equal to a preset second number threshold (e.g., 1), and the first number threshold is greater than the second number threshold.

In the scene, the second type comprises a video browsing type, when different types of videos are watched by using video streams, due to asymmetry existing in uploading and downloading, the number of antennas can be dynamically adjusted in time according to the video flow, and when the flow is required to be high-speed, the relay node uses 2 (the first number) transmitting antennas and 1 (the second number) receiving antenna to reduce the receiving power consumption; when the required flow is low, 1 (second number) line transmitting antenna and 1 (second number) receiving antenna can be used, and the transmitting power consumption is reduced.

In another scenario, when the communication type is a third type, the number of receive antennas is set to a second number and the number of transmit antennas is set to the second number.

Wherein the second number is less than or equal to a preset second number threshold (e.g., 1).

In such a scenario, the third type includes a web browsing type, and when the user performs low-traffic communication such as web browsing, the relay node uses 1 (second number) of transmitting antennas and 1 (second number) of receiving antennas, so as to reduce power consumption for transmission and reception.

Of course, the above adjustment modes of the antennas are only used as examples, and when implementing the embodiment of the present invention, adjustment modes of other antennas may be set according to actual situations, for example, 3 transmitting antennas and 3 receiving antennas are set, 1, 2, or 3 transmitting antennas are dynamically selected according to the traffic of the video, and the like, which is not limited in the embodiment of the present invention. In addition, besides the above antenna adjustment methods, those skilled in the art may also adopt other antenna adjustment methods according to actual needs, and the embodiment of the present invention is not limited thereto.

In practical applications, the number of transmitting antennas and the number of receiving antennas can be adjusted by wl instructions, which are exemplified as follows:

As shown in fig. 3, it is assumed that there are a living room, a kitchen, two bedrooms (including a main bed and a secondary bed) and a study room in a house, wherein the main bed is close to the study room, and the secondary bed is close to the kitchen.

In this example, the router 32 is placed in the living room, the router 32 accesses the base station 31, and as a wireless node, broadcasts a Wi-Fi signal.

Since the Wi-Fi signal is weak in the main bed, the sub bed, the study room and the kitchen due to a large living room area and wall obstruction, it is possible to place the mobile terminal 332 in the living room, place the mobile terminal 331 near the main bed, place the mobile terminal 3313 near the study room, place the mobile terminal 3321 near the sub bed and the kitchen, place the mobile terminal 33213 near the kitchen, and place the mobile terminal 33211 near the sub bed.

In the living room:

the mobile terminal 331 accesses the route 32 through the station node and starts the softAP node as a relay node of the first stage to relay the Wi-Fi signal to the master-slave.

The mobile terminal 332 accesses the route 32 through the station node and starts the softAP node as a relay node of the first level to relay the Wi-Fi signal to other parts of the living room (e.g., the balcony), respectively.

The laptop 333 is used as an application terminal to access the router 32 for the user to work, entertain, etc. in the living room.

The mobile terminal 3321 accesses the mobile terminal 332 through the station node and starts the softAP node as a relay node of the second level to relay Wi-Fi signals to the secondary-lying, kitchen.

The intelligent coffee machine 3322 and the intelligent water dispenser 3323 are used as application terminals to access the mobile terminal 332.

In the master-lying:

the tablet computer 3311, the PDA 3312, and the mobile terminal 3314 are connected to the mobile terminal 331 as application terminals for the user to work, entertain, and so on in the home position and the bed position.

The mobile terminal 3313 accesses the mobile terminal 331 through the station node and starts the softAP node as a relay node of the second stage to relay the Wi-Fi signal to the study room.

In the study room:

the PC 33131 and the mobile terminal 33132 are connected to the mobile terminal 3313 as application terminals for the user to work, entertain and so on in the study.

In the secondary lying:

the mobile terminal 33211 accesses the mobile terminal 3321 through the station node and starts the softAP node as a relay node of the third level to relay Wi-Fi signals to the second level.

The electronic game machine 332111, the television 332112, and the mobile terminal 332113 are connected to the mobile terminal 33111 as application terminals for the user to perform work, entertainment, and the like in the study.

In the kitchen:

the mobile terminal 3322 accesses the mobile terminal 3321 through the station node and starts the softAP node as a relay node of the third stage to relay Wi-Fi signals to the kitchen.

The intelligent refrigerator 332121, the intelligent microwave oven 332122 and the intelligent kitchen oven 332123 are used as application terminals to access the mobile terminal 33112.

Referring to fig. 4, a flowchart illustrating steps of another configuration method for relay communication according to an embodiment of the present invention is shown, and is applied to a mobile terminal, where the mobile terminal is configured with a Wi-Fi module, where the method specifically includes the following steps:

step 401, receiving, by the softAP node, a data packet sent by the application terminal and/or the relay node of the next stage.

When the application terminal communicates with a target device (such as a web server) of an external network, the data packet generated by the application terminal is transmitted step by step through the relay node until the data packet is sent to the target device.

And 402, forwarding the data packet from the softAP node to the station node.

In specific implementation, as the packet forwarding function is started, the data packet can be forwarded from the softAP node to the station node, so that forwarding of the data packet inside the relay node is realized.

Step 403, sending the data packet to the router or the relay node at the upper stage through the station node according to the communication configuration parameter.

In practical application, the data packet may be processed according to communication configuration parameters of different relay levels, so as to implement relay communication.

In one embodiment of the present invention, step 403 may include the following sub-steps:

and a substep S21, when the data packet has the uniform resource locator URL, inquiring the gateway address of the domain name system DNS.

And a substep S22, sending the data packet to the upper level router or the relay node through the station node according to the gateway address.

In the embodiment of the invention, the URL is analyzed when the application terminal accesses the webpage and the like.

If the gateway address of the DNS of the mobile terminal is the IP address of the relay node at the upper stage, the packet for resolving the URL can be forwarded to the relay node at the upper stage.

And the gateway address of the DNS of the relay node of the current level is the IP address of the relay node of the previous level, the packet for resolving the URL may be forwarded to the relay node of the previous level.

And until the D NS reaches the first-stage relay node, the gateway address of the D NS is the IP address of the router, the data packet for resolving the URL can be forwarded to the router, and the router sends the data packet to a server for providing domain name resolution for the external network and maps the URL to the IP address. In another embodiment of the present invention, step 302 may include the following sub-steps:

and a substep S23, converting the source address in the data packet from the IP address of the application terminal to the IP address of the mobile terminal when the relay level is the first level.

And a substep S24 of transmitting the packet disguised from the IP address of the mobile terminal to the router at the upper stage through the station node.

For the relay node in the first level, the source address (i.e. the IP address of the mobile terminal) in the packet, such as 192.168.49.0, may be disguised as the IP address of the mobile terminal itself, such as 0.0.0.0, based on the NAT configuration information, and forwarded to the router.

In another embodiment of the present invention, step 303 may comprise the sub-steps of:

and a substep S25, when the relay level is at or below the second level,

In the embodiment of the present invention, for the relay node at the second level or below the second level, the data packet may be directly forwarded to the relay node at the upper level.

And step 404, receiving a data packet sent by the router or the relay node at the upper stage through the station node.

When the target device of the external network communicates with the application terminal, the data packet generated by the target device is transmitted to the relay node (i.e. the mobile terminal) hop by hop until the data packet is sent to the application terminal.

Step 405, forwarding the data packet from the station node to the softAP node.

In specific implementation, as the packet forwarding function is started, the data packet can be forwarded to the softAP node from the node station, so as to implement forwarding of the data packet inside the relay node.

And step 306, sending the data packet to a next-level application terminal or a next-level relay node through the softAP node according to the communication configuration parameters.

In one embodiment of the present invention, step 406 may include the following sub-steps:

and a substep S31, converting the destination address in the data packet from the IP address of the mobile terminal to the IP address of the application terminal when the relay level is the first level.

And a substep S32, when the relay level is the second level or below, inquiring a source address in the data packet to obtain the IP address of the application terminal.

And a substep S33 of querying a target path from the IP address of the mobile terminal to the IP address of the application terminal through the relay routing tables between the relay nodes at each stage.

And a substep S34, inquiring the IP address of the application terminal or the relay node of the next stage in the target path.

And a substep S35, sending the data to the next-stage application terminal or relay node by the softAP node according to the IP address of the next-stage application terminal or relay node.

For the relay node of the first stage, the second IP address of the station node from which the packet originates may be determined, and the first IP address corresponding to the second IP address is looked up in the routing table, so that the packet may be forwarded to the softAP node to which the first IP address belongs.

For the relay node in the first level, the destination address in the packet (i.e. the IP address of the mobile terminal itself), for example, 0.0.0.0, may be translated into the IP address of the application terminal, for example, 192.168.49.0, based on the configuration information of the NAT. For each stage of relay node, since a plurality of relay nodes can be connected, that is, there are a plurality of routes to the application terminal, when a data packet is sent down, the destination address in the data packet can be queried to determine the application terminal to which the data packet is sent.

And inquiring a relay routing table to obtain a target path which can be routed to the application terminal, inquiring the IP address of the next-stage mobile terminal or the relay node from the path, and forwarding the data packet to the IP address.

If the next level is the application terminal, the data packet is sent to the application terminal through the softAP node, and the application terminal performs corresponding processing, such as loading a webpage, playing a video and the like.

If the next stage is a relay node, the softAP node transmits the packet to the relay node, and the relay node can continue to perform downward relay communication.
