All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

The flow diagrams depicted in the figures are merely illustrative and not necessarily all of the elements and operations/steps are included or performed in the order described. For example, some operations/steps may be further divided, combined, or partially combined, so that the order of actual execution may be changed according to actual situations.

In the following description, suffixes such as "module", "component", or "unit" for representing elements are used only for facilitating the description of the present application, and have no specific meaning in themselves. Thus, "module," "component," or "unit" may be used in combination.

Before describing embodiments of the present application in detail, techniques related to the embodiments of the present application are described.

Referring to fig. 1, in the conventional art, a public network IP address (for example, 1.1.1 in the drawing) acquired from a wide area network (WAN, wide Area Network) by a wireless router (for example, customer premise equipment (CPE, customer Premi se Equipment) in the drawing) is configured on a network port on the WAN side of the wireless router, IP addresses acquired by users (i.e., LAN devices) of a local area network (LAN, local Area Network) of the wireless router are private network IP addresses allocated by the wireless router (for example, private network IP addresses of two users of the local area network are 192.168.0.100 and 192.168.0.101 in the drawing, respectively), a private network gateway address on a Bridge is 192.168.0.1, one user is connected to the private network gateway of the Bridge through an RJ45 interface, one user is connected to the private network gateway of the Bridge through WIFI, the wireless router maps the private network IP address with the public network IP address through a network address translation (NAT, network Address Translation) function, and source IP of a packet sent by the user of the LAN is converted into a private network IP address, and the private network address is converted into a public network IP address through the NAT, thereby achieving communication between the public network address and the WAN.

With the explosive growth of mobile internet, internet of things and industry applications, future mobile communications will face thousands of data traffic increases and billions of device networking demands. The 5G is taken as the development direction of the new generation mobile communication technology, and further meets the mass requirements of the application of the Internet of things in the future on the basis of improving the service experience of the mobile Internet, and is deeply integrated with industries such as industry, medical treatment, traffic and the like, so that real 'everything interconnection' is realized.

The new trend of 5G networks, especially new services, new architecture, and new technology, requires the use of public IP addresses for end-to-end communication along with the application of new and old services such as voice over IP (VoIP, voice over Internet Protocol), interactive internet protocol television (IPTV, internet Protocol TV or Interactive Personal TV), IP telephone (IP Phone), TR069 protocol (TR 069, technical Report 069), and the like. In the traditional NAT mode wireless router, the IP address acquired by the user of the local area network is a private network IP address distributed by the wireless router, the private network IP address cannot be transmitted and used on the wide area network, and after NAT conversion, the source IP address of the data packet sent by the user of the local area network is replaced by a public network IP address from the private network IP address. In conventional NAT mode, wireless routers are unable to meet the needs of these services. Specific scenarios for these business requirements include: adapting older tablet devices; adapting downstream routers to realize the mobilization of the routers; an outdoor Unit (ODU, out Door Unit) device adapts to an indoor Unit (IDU, in Door Unit) device, and the like.

VoIP is a voice call technology that enables voice calls and multimedia conferences via internet protocol (IP, internet Protocol), i.e., communication via the internet. IPTV is a brand-new technology that utilizes a broadband cable network, integrates multiple technologies such as the internet, multimedia, communication, and the like, and provides multiple interactive services including digital television to home users. TR069 is a technical specification, which is a management protocol of an application layer, named "CPE wide area network management protocol"; TR069 defines a set of brand-new network management system structure, including management model, interaction interface and basic management parameters, which can effectively implement management of home network equipment. Both IDU and ODU are part of a microwave communication station; the IDU is responsible for completing service access, multiplexing and modulation demodulation and converting service signals into intermediate frequency analog signals indoors; the ODU is responsible for completing frequency conversion and amplification of signals, and then converts radio frequency signals into electromagnetic waves through an antenna, and radiates the electromagnetic waves into the air, or receives the electromagnetic waves, converts the electromagnetic waves into radio frequency signals, and sends the radio frequency signals to the IDU.

Referring to fig. 4, fig. 4 is a schematic structural diagram of an embodiment of a wireless router, including: a bridge 10 and a DHCP service module 20.

The network bridge 10 is provided with a private network gateway and a public network gateway, and the network bridge 10 receives a first application of requesting to distribute an IP address of a first device of a local area network through the private network gateway; the DHCP service module 20 assigns a public network IP address acquired from the wide area network to the first device in response to the first application, so that the first device connects to the wide area network through a public network gateway of the bridge using the public network IP address.

In an embodiment, the wireless router further comprises: wireless dialing module 30, routing module 40, and subscriber access list module 50.

The wireless dialing module 30 is configured to obtain the public network IP address from the wide area network after being connected to the wide area network, broadcast a dialing success event, and send the public network IP address to other modules; and broadcasting a disconnection message after disconnecting from the wide area network.

The wireless dialing module 30 is mainly responsible for establishing or disconnecting a packet data protocol (PDP, packet Data Protocol) connection with a wide area network, after establishing the PDP connection, the wireless dialing module 30 obtains a public network IP address from the wide area network, and then broadcasts a successful dialing event and sends information carrying the public network IP address to other modules. After receiving the dialing success event, the other DHCP service module 20 and the routing module 40 perform corresponding processing.

The routing module 40 is configured to calculate a public network gateway address by using a subnet mask and the public network IP address and add the public network gateway address to the bridge 10 when the public network IP address penetration function is turned on after receiving the dialing success event; replacing the IP address of the wide area network card of the wireless router with a second private network IP address; configuring a downlink public network routing rule to enable a data packet with a destination IP address being the public network IP address from the wide area network to be routed to an interface of a public network gateway of the bridge 10; and adding a source address conversion function to enable the second equipment which acquires the first private network IP address and the wireless router of the second private network IP address to be connected with the wide area network.

In the embodiment of the application, a source address conversion function is added, so that the source IP address of the data packet of the second device can be replaced by the public network IP address from the first private network IP address, and the data packet after the source IP address is replaced is sent to the destination IP address, wherein the destination IP address is the wide area network IP address, so that the second device can be connected with the wide area network, and the source IP address of the wireless router can be replaced by the public network IP address from the second private network IP address, and is connected with the wide area network through the public network IP address.

The DHCP service module 20 is further configured to assign a first private IP address to a second device of the local area network; before a dialing success event is received, a second address pool with at least one private network IP address is configured; after receiving the dialing success event, under the condition that the public network IP address penetrating function is started, adding a first address pool with the public network IP address, and restarting to enable the DHCP service module 20 to preferentially allocate the public network IP address to the first accessed first equipment; and deleting the first address pool after receiving the disconnection message, and notifying the first equipment allocated with the public network IP address to re-request for allocation of the private network IP address.

The subscriber access list module 50 is configured to notify the DHCP service module 20 to release the public network IP address when it is monitored that the first device allocated with the public network IP address is offline, and clear the recording time of allocating the public network IP address so that the next third device requesting to allocate the IP address obtains the public network IP address again.

According to the embodiment of the application, the wide area network is allocated to the public network IP address of the wireless router, and the public network IP address is transmitted to the first equipment in the local area network equipment through the wireless router, so that the problem that the public network IP address needs to be used by the local area network equipment in a special application scene can be effectively solved, the use scene of the wireless router is enlarged, and the competition capability of the wireless router is improved.

The following describes the method flow and steps in the embodiment of the present application in detail with reference to fig. 4, 5 and 6, and the detailed steps of the intercommunication flow between the modules of the wireless router are as follows:

step C100: the wireless dialing module 30 establishes a PDP connection with the wide area network, acquires a public network IP address (1.1.1.1 is a public network IP address shown in fig. 6) from the wide area network, then broadcasts a dialing success event, and sends information carrying the public network IP address to the other routing module 40 and the DHCP service module 20.

Step C101: the routing module 40 receives the dial-up success event, if the public network IP penetration function is turned on, calculates a public network gateway address (1.1.1.2 is shown in fig. 6 as a public network gateway address) using the subnet mask and the public network IP address, and adds the public network gateway to the bridge by commanding "IP addr add wan_gateway/32scope link dev bridge0". At this time, the bridge 10 has two addresses (192.168.0.1 in fig. 6 is a private gateway address) of a public gateway and a private gateway.

Step C102: the routing module 40 replaces the wireless router wide area network WAN network card IP address with the second private network IP address by the command "if config wan_interface 169.254.3.2netmask255.255.255.255up" (169.254.3.2 shown in fig. 6 is the second private network IP address). The wireless router no longer uses the public network IP address but uses the second private network IP address.

Step C103: the routing module 40 configures a downstream public network routing rule to route packets from the wide area network, whose destination address is a public network IP address, to the interface of the public network gateway of the bridge 10 using the command "IP route add wan_ipaddr/32dev bridge0". And an SNAT function is added, so that a second device which acquires the IP address of the first private network can access the network resource of the wide area network, and a command of 'iptables-t nat-IPOSTROUTING-o wan_interface-j SNAT-to wan_ipaddr' is used. After the routing module 40 has configured the routing rules, it notifies the DHCP service module 20 to update the address pool information.

Step C104: after the DHCP service module 20 receives the notification, it adds a first address pool of public network IP addresses, where only the public network IP addresses, that is, the public network IP addresses obtained from the wide area network by the wireless dialer module 30, in the first address pool, and then restarts the DHCP service module 20, so that the DHCP service module 20 preferentially allocates the public network IP addresses to the first accessed first device.

Step C105: after the public network IP address is assigned to the first device, the subscriber access list module 50 monitors whether the first device is online, if the first device is offline, notifies the DHCP service module 20 to immediately release the public network address, clears the recording time of the assigned public network IP address, and after clearing the assigned recording time, the next third device can acquire the public network IP address again.

Step C106: when the wireless dialing module 30 broadcasts a disconnect PDP connection message, the routing module 40 deletes the public network gateway address on the bridge 10, retains the private network gateway address, and deletes the public network routing rule information; the DHCP service module 20 deletes the first address pool and notifies the first device that acquires the public network address to re-request allocation of the private network IP address, and all lan devices can only acquire the private network IP address.

The embodiment of the application can improve the application scene and the competitive capacity of the wireless router, does not relate to hardware, and has universal portability.

A terminal device, comprising a communication circuit, a memory, and a processor, the communication circuit configured to communicate; the memory is used for storing a computer program; the processor is configured to execute the computer program and to implement the public network address penetration method of a terminal device according to any of claims 1-6 when the computer program is executed.

8. A computer readable storage medium, characterized in that the computer readable storage medium stores a computer program, which when executed by a processor causes the processor to implement the public network address penetration method of a terminal device according to any of claims 1-6.

9. A wireless router, the wireless router comprising:

and the dynamic host configuration protocol service module responds to the first application and distributes the public network IP address acquired from the wide area network to the first equipment so that the first equipment is connected with the wide area network through the public network gateway of the network bridge by using the public network IP address.

10. The wireless router of claim 9, wherein said wireless router further comprises:

the wireless dialing module is used for acquiring the public network IP address from the wide area network after being connected with the wide area network, broadcasting a dialing success event and sending the public network IP address to other modules; broadcasting a disconnection message after disconnecting from the wide area network;

the routing module is used for calculating a public network gateway address by using a subnet mask and the public network IP address under the condition that a public network IP address penetration function is started after a dialing success event is received, and adding the public network gateway address to the network bridge; replacing the IP address of the wide area network card of the wireless router with a second private network IP address; configuring a downlink public network routing rule to enable a data packet with a destination IP address of the public network IP address from the wide area network to be routed to an interface of a public network gateway of the network bridge; adding a source address conversion function to enable the second device which acquires the first private network IP address and the wireless router of the second private network IP address to be connected with the wide area network;

the user access list module is used for notifying the DHCP service module to release the public network IP address when the first equipment distributed with the public network IP address is monitored to be offline, and clearing the record time distributed with the public network IP address so that the third equipment requiring to distribute the IP address next can acquire the public network IP address again;

the dynamic host configuration protocol service module is further used for distributing the first private network IP address to the second equipment of the local area network; before a dialing success event is received, a second address pool with at least one private network IP address is configured; after a dialing success event is received, under the condition that a public network IP address penetrating function is started, a first address pool with the public network IP address is additionally configured, and then the first device is restarted, so that the dynamic host configuration protocol service module preferentially distributes the public network IP address to first accessed first equipment; and deleting the first address pool after receiving the disconnection message, and notifying the first equipment allocated with the public network IP address to re-request for allocation of the private network IP address.
