[0031] 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. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present application.

[0032] Next, the specific embodiments of the network system based on a wireless bridge disclosed in the embodiments of the present application will be exemplarily described.

[0033] As shown in Figure 1 Fig. 1, the network system based on a wireless bridge disclosed in the embodiments of the present application includes a first wireless bridge device 110 and a POP (Point Of Presence, access point) device 120, wherein the first wireless bridge device 110 is built-in with a user identification card of a 5G (5th Generation Mobile Communication Technology, 5th generation mobile communication technology) customized network, and the POP device 120 and the first wireless bridge device 110 are configured with a fixed IP address in the 5G customized network. The functions of the first wireless bridge device 110 and the POP device are as follows respectively.

[0034] The first wireless bridge device 110 is configured to access the 5G customized network through a wireless signal.

[0035] The POP device is configured to access the 5G customized network through a preset dedicated line, and to establish a 5G customized network dedicated line connection between the first wireless bridge device and a target IP address.

[0036] The 5G customized network refers to a dedicated line network realized based on VPDN (Virtual Private Dialup Networks, virtual private dialup network) technology, which is isolated from a public network. The preset dedicated line is a self-operated dedicated line of a 5G customized network operator.

[0037] Wireless bridge is the bridge of wireless network, which uses wireless transmission to build a bridge between two or more networks. In the prior art, the connection mode of wireless bridge includes: point-to-point type and relay mode. Among them, the point-to-point type is "direct transmission". For example, two fixed networks located in different buildings are connected by wireless bridge equipment. They are generally composed of a pair of bridges and a pair of antennas. When connected in relay mode, two wireless bridges are connected through the same wireless bridge for signal transmission.

[0038] In the embodiments of the present application, the brand and model of the wireless bridge are not limited. Optionally, the first wireless bridge device 110 can be a 5G wireless bridge commonly used in the prior art. Before using the first wireless bridge device 110, a 5G customized network user identification card needs to be applied and installed in the first wireless bridge device 110.

[0039] In some embodiments of the present application, the first wireless bridge device 110 is further used for virtual private dialup network dialing to connect the POP device associated with the virtual private dialup network.

[0040] The first wireless bridge device 110 is pre-installed with dial-up Internet access function. After the first wireless bridge device 110 is powered on, the pre-installed dial-up Internet access function in the first wireless bridge device 110 starts running, performs virtual private dialup network dialing, and accesses the 5G customized network.

[0041] Virtual private dialup network (VPDN) refers to dial-up access to the Internet, transmission of private data on the public network through packet and encryption of network data, reaching the security level of private network, and using the architecture of public switched telephone network to build private network of enterprises and institutions.

[0042] In the embodiments of the present application, the POP device is a device supporting VPDN technology.

[0043] In the network system based on wireless bridge disclosed in the embodiments of the present application, the first wireless bridge device 110 is a client, the POP device is a server, and the first wireless bridge device 110 connects the POP device by dialing the VPDN.

[0044] Before the first wireless bridge device 110 accesses the 5G customized network, a fixed IP address is allocated to the first wireless bridge device 110 by the 5G customized network operation system. After the first wireless bridge device 110 dials the virtual private dialup network, the service management center of the virtual private dialup network establishes a communication link between the first wireless bridge device 110 and the POP device.

[0045] In some embodiments of the present application, the performing virtual private dial-up network dial-up, connecting the POP device associated with the virtual private dial-up network comprises: performing virtual private dial-up network dial-up according to preset configuration data, so that the virtual private dial-up network performs fragmentation on the service associated with the first wireless bridge device, and allocates a 5G customized network dedicated line between the first wireless bridge device and the POP device according to the fragmentation result.

[0046] Optionally, the first wireless bridge device 110 has pre-stored configuration data. The configuration data includes dial-up configuration. After the first wireless bridge device 110 is powered on, the first wireless bridge device 110 starts running with the preset dial-up online function, performs virtual private dial-up network dial-up based on the dial-up configuration, and accesses the 5G customized network.

[0047] In some embodiments of the present application, the dial-up configuration can include user name and password, website address of the virtual private dial-up network, and the like.

[0048] Optionally, in the 5G customized network implemented based on the 5G fragmentation technology, after the first wireless bridge device 110 dials up the virtual private dial-up network according to the preset configuration data, the service management center of the virtual private dial-up network fragments the service of the first wireless bridge device 110 according to the service type corresponding to the first wireless bridge device 110, allocates a logical network (i.e. network slice) for the service of the first wireless bridge device 110, and stores the allocated logical network in association with the first wireless bridge device 110. Then, the service management center associates the logical network with the POP device, thereby allocating a 5G fragmentation dedicated line between the first wireless bridge device and the POP device, so as to improve the data transmission speed between the first wireless bridge device and the POP device.

[0049] When a user needs to access the Internet through the first wireless bridge device 110, the 5G dedicated line configuration information corresponding to the first wireless bridge device 110 needs to be stored in the 5G customized network operation system according to the port configuration of the first wireless bridge device 110 by the user and the network service applied by the user. The 5G dedicated line configuration information includes: routing information from the first wireless bridge device to a target IP address, tunnel configuration information required for establishing a 5G customized network dedicated line between the first wireless bridge device and the target IP address, service configuration information, IP address of the first wireless bridge device, port connection information, target IP address, and the like.

[0050] In the embodiments of this application, the POP device 120 is further configured to: in response to the dial-up connection of the first wireless bridge device 110, establish a 5G customized network leased line connection between the first wireless bridge device 110 and the target IP address according to the 5G leased line configuration information corresponding to the first wireless bridge device 110.

[0051] As a server, after receiving the dial-up connection from the first wireless bridge device 110, the POP device 120 establishes a 5G customized network leased line connection between the first wireless bridge device 110 and the target IP address based on the 5G leased line configuration information corresponding to the first wireless bridge device 110. For example, the POP device 120 can establish the 5G customized network leased line connection between the first wireless bridge device 110 and the target IP address through the VPDN service management center.

[0052] When the target IP address is a device in a different network, the POP device will use different methods to establish a 5G customized network private line between the first wireless bridge device and the device corresponding to the target ID address.

[0053] The following examples illustrate the specific implementation methods for establishing a 5G customized network private line corresponding to the first wireless bridge device using POP devices, in different application scenarios.

[0054] like Figure 2 As shown, in one application scenario, the network system further includes a second wireless bridge device 130.

[0055] Correspondingly, the target IP address is a fixed IP address of the second wireless bridge device in the 5G customized network, the 5G private line configuration information includes: tunnel information, service information, and an IP address of the second wireless bridge device, and the establishing of the 5G customized network private line connection between the first wireless bridge device and the target IP address according to the 5G private line configuration information corresponding to the first wireless bridge device in response to the dial-up connection of the first wireless bridge device includes: establishing a GRE (Generic Routing Encapsulation) tunnel and an LDP (Label Distribution Protocol) tunnel with the first wireless bridge device and the second wireless bridge device respectively, and opening MPLS (Multi-Protocol Label Switching) and L2VPN (Layer 2 Virtual Private Network) in the GRE tunnel and the LDP tunnel to establish the 5G customized network private line connection between the first wireless bridge device and the second wireless bridge device. Wherein, the second wireless bridge device is built-in with a user identification card of the 5G customized network, and the IP address of the second wireless bridge device is bound with the user identification card.

[0056] In the application scenario shown in FIG. 1, when user 1 needs to communicate with user 2 in the 5G customized network, user 1 can apply for a user identification card of the 5G customized network and obtain a fixed IP address corresponding to the user identification card. Then, user 1 installs the user identification card in the wireless bridge device (i.e. the first wireless bridge device) in the A place, and connects the electronic device in the A place to the corresponding port of the wireless bridge device. Figure 2 In the application scenario shown in FIG. 1, when user 1 needs to communicate with user 2 in the 5G customized network, user 1 can apply for a user identification card of the 5G customized network and obtain a fixed IP address corresponding to the user identification card. Then, user 1 installs the user identification card in the wireless bridge device (i.e. the first wireless bridge device) in the A place, and connects the electronic device in the A place to the corresponding port of the wireless bridge device.

[0057] The network system in the embodiments of the present application also needs to be configured.

[0058] For example, User 1 needs to predefine the port connection configurations of the first and second wireless bridge devices, and report these port connection configurations to the 5G customized network operation system for storage. On the other hand, User 1 also needs to configure the routing information of the first and second wireless bridge devices and report the configured routing information to the 5G customized network operation system for storage. As another example, the 5G customized network operator also needs to configure the following information associated with the 5G customized network leased line for User 1 according to User 1's subscription agreement: POP device IP address, tunnel information, and service information. The 5G customized network operation system stores the port connection configuration, routing configuration, tunnel information, and service information of each bridge device as the 5G leased line configuration information for that bridge device, for use in subsequent establishment of the 5G customized network leased line.

[0059] After completing the hardware connection and network configuration, when the first and second wireless bridge devices are powered on, they perform virtual private dial-up network dialing to access the 5G customized network.

[0060] The virtual private dial-up network of the 5G customized network locates the POP device based on the 5G leased line configuration information of the first wireless bridge device and the second wireless bridge device, and sends the access requests of the first wireless bridge device and the second wireless bridge device to the POP device. Then, the POP device establishes GRE tunnels and LDP tunnels with the first wireless bridge device 110 and the second wireless bridge device 130 respectively, based on the 5G leased line configuration information of the first wireless bridge device 110 and the second wireless bridge device 130, and enables MPLS and L2VPN in the GRE tunnels and the LDP tunnels, thereby establishing a 5G customized network leased line connection between the first wireless bridge device 110 and the second wireless bridge device 130 via the POP device 120.

[0061] like Figure 2 As shown, after user 1 configures a route from the gei0 / 1 port of the first wireless bridge device 110 to the gei0 / 1 port of the second wireless bridge device 130, the POP device will establish a 5G customized network leased line from the gei0 / 1 port ① of the first wireless bridge device 110 through wireless line ② -> 5G customized network base station -> preset leased line ⑧ -> POP device 120 -> wireless line ⑦ -> gei0 / 1 port ⑥ of the second wireless bridge device 130, for data transmission between the first wireless bridge device 110 and the second wireless bridge device 130.

[0062] The specific implementation of the POP device establishing the GRE tunnel and the LDP tunnel with the first wireless bridge device 110 and the second wireless bridge device 130 is described in the prior art, and thus will not be repeated here.

[0063] The specific implementation of the POP device opening the MPLS and the L2VPN in the GRE tunnel and the LDP tunnel is described in the prior art, and thus will not be repeated here.

[0064] The GRE tunnel can realize two-layer network data communication, and the LDP tunnel is used for label distribution and is assisted by the tunnel protocol. Through the establishment of the GRE tunnel and the LDP tunnel, the transparent transmission of data in network connection can be realized. The connection method uses VPN (Virtual Private Network) security encryption algorithm and other technologies to realize the secure and transparent transmission of two-layer data (Ethernet data packets).

[0065] Compared with the point-to-point connection method of the bridge in the prior art, the network system based on the wireless bridge disclosed in the embodiments of the present application has higher data security. Moreover, with the help of the 5G customized network special line technology, the deployment distance and the deployment position between the first wireless bridge device and the second wireless bridge device are not limited, the networking is more convenient and flexible, and has higher application scene robustness.

[0066] In another application scenario, the target IP address is the IP address of a local device. As shown in Figure 3 The network system includes a first wireless bridge device 110, a POP device 120, and a local device 140. The first wireless bridge device 110 can access the local device 140 through the POP device 120, and access the Internet, a local area network, or other local devices through the local device 140.

[0067] Optionally, the local device includes any one of the following: a multi-service transport platform (MSTP), an IP radio access network (IPRAN), and a metropolitan area network switch.

[0068] In the embodiments of this application, the 5G customized network operation system pre-configures the interface ports between the POP device and each central office device, and stores the port configuration information of the POP device. For example, the port configuration information of the POP device may include: the correspondence between the port number of the POP device and the IP address and / or VLAN (Virtual Local Area Network) identifier of the central office device. The VLAN identifier can be an identifier for a VLAN based on the port number.

[0069] Optionally, the POP device 120 and the central office device 140 can be physically connected via optical or electrical ports. By providing multiple types of access ports, various physical line connection methods can be supported after the POP device, making the deployment of 5G customized network private lines more flexible and applicable to a wider range of scenarios.

[0070] The target IP address is the IP address of the central office equipment of the 5G customized network. The 5G leased line configuration information includes: tunnel information, service information, and the IP address of the central office equipment. The step of responding to the dial-up connection of the first wireless bridge device and establishing a 5G customized network leased line connection between the first wireless bridge device and the target IP address according to the 5G leased line configuration information corresponding to the first wireless bridge device includes: establishing a GRE tunnel and an LDP tunnel with the first wireless bridge device, and opening MPLS and L2VPN in the GRE tunnel and the LDP tunnel to establish a 5G customized network leased line connection from the POP device to the central office equipment.

[0071] by Figure 3 Taking the illustrated application scenario as an example, when User 1's electronic device located in location A needs to access the Internet or other devices through the central office equipment 140, User 1 can apply for a 5G customized network user identification card and obtain a fixed IP address corresponding to this user identification card. Then, User 1 installs the user identification card in the wireless bridge device (i.e., the first wireless bridge device) located in location A, and connects the electronic device in location A that needs to access the central office equipment to the corresponding port of the local wireless bridge device.

[0072] When configuring the network, the user 1 needs to define the port docking configuration of the first wireless bridge device in advance (for example, including: access port of the electronic device, access port of other services, etc.), and report the port docking configuration of the bridge device to the 5G customized network operation system for storage. On the other hand, the user 1 also needs to configure the routing information of the first wireless bridge device, and report the configured routing information to the 5G customized network operation system for storage. For another example, the 5G customized network operator also needs to associate the POP device IP address, tunnel information, and service information for the user 1 according to the subscription agreement of the user 1. The 5G customized network operation system stores the port docking configuration, routing configuration, and tunnel information, service information and other configuration information of each bridge device as the 5G private line configuration information of the bridge device, which is used for subsequent establishment of 5G customized network private line.

[0073] After completing the hardware connection and network configuration, when the first wireless bridge device is powered on, the first wireless bridge device performs virtual private dial-up network dial-up to access the 5G customized network.

[0074] The virtual private dial-up network of the 5G customized network finds the POP device according to the 5G private line configuration information of the first wireless bridge device. Then, the POP device 120 establishes a GRE tunnel and an LDP tunnel with the first wireless bridge device 110 according to the 5G private line configuration information of the first wireless bridge device 110, and opens MPLS and L2VPN in the GRE tunnel and the LDP tunnel, thereby establishing the 5G customized network private line connection between the first wireless bridge device 110 and the POP device 120. In this way, the 5G customized network private line connection between the first wireless bridge device 110 and the POP device 120, and the direct connection line between the POP device 120 and the local device 140, constitute the 5G customized network private line connection of the first wireless bridge device 110 connected to the local device 140. The direct connection line between the POP device 120 and the local device 140 can be a network cable or an optical fiber.

[0075] Further, the 5G customized network private line connection between the first wireless bridge device 110 and the POP device 120 is established by the virtual private dial-up network of the 5G customized network, and the direct connection line between the POP device 120 and the local device 140 is established by the direct connection line between the POP device 120 and the local device 140. Figure 4As shown in the network topology diagram, when user 1 needs to access the Internet through the metropolitan area network switch of the 5G customized network, after user 1 configures the port pair relationship from the gei0 / 1 port of the first wireless bridge device 110 to the port of the Internet, the 5G customized network running system generates the 5G private line configuration information of the first wireless bridge device 110 according to the service demand of user 1, and the POP device will establish a 5G customized network private line from the gei0 / 1 port ① of the first wireless bridge device 110, through the wireless line ②->5G customized network base station->preset private line ⑧->POP device 120->optical fiber or cable ⑨->metropolitan area network switch ④, for the first wireless bridge device 110 to access the Internet through the metropolitan area network switch 140.

[0076] When the optical cable interruption cannot be repaired in time, and user 1 cannot access the Internet through the optical cable, the wireless access segment optical path can be replaced by a wireless access segment, and the 5G bridge device is immediately enabled to establish a connection with the Internet service port pre-deployed by the POP device, thereby replacing the original optical fiber line and achieving the purpose of quickly repairing the service. Figure 4

[0077] In the specific use process, when the optical cable is interrupted, user 1 only needs to connect the network cable of the electronic device to the preset gei0 / 2 port of the 5G bridge device, without changing the network cable connection position and configuration (such as IP address and other parameters) of the electronic device, so as to restore the communication and realize the transparent transmission. The single 5G bridge device uses single-pass wireless routing, has higher speed and smaller time delay. Moreover, the 5G customized network private line uses two-layer network data transmission, and has higher security.

[0078] In some embodiments of the present application, the POP device and the local device are physically connected through an optical port or an electrical port, including that the POP device opens a sub-interface on the optical port or the electrical port connected with the local device, and divides each sub-interface and the VLAN of the local device.

[0079] Optionally, the VLAN of the local device can be created based on the port. For example, each port of the local device corresponds to a VLAN, or each sub-interface of the POP device corresponds to a VLAN.

[0080] For example, when multiple electronic devices of user 1 need to access the multi-service transmission platform (i.e. the local device 140) through the first wireless bridge device 110, the POP device needs to create a data transmission line for each electronic device. In order to save the port resources of the POP device, the POP device opens a sub-interface on the port connected with the local device, encapsulates the sub-interface using the dot1q protocol in the trunk mode, and establishes a 5G customized network private line from each sub-interface to the local device.​

[0081] For example, as shown in the network topology, Figure 5 For example, as shown in the network topology,

[0082] In the process of dialing the virtual private dial-up network and accessing the 5G customized network, on the one hand, the POP device 120 establishes the GRE tunnel and the LDP tunnel with the first wireless bridge device 110 according to the 5G private line configuration information of the first wireless bridge device 110, and opens the MPLS and L2VPN in the GRE tunnel and the LDP tunnel, thereby establishing the 5G customized network private line connection between the first wireless bridge device 110 and the POP device 120. On the other hand, the POP device opens two sub-interfaces to establish two lines (for example, corresponding to VLAN100 and VLAN200 respectively) of the electronic device pc1 and pc2 and the multi-service transmission platform (MSTP), so as to save the physical port of the POP device while ensuring that the electronic device pc1 and pc2 can access the multi-service transmission platform at the same time.

[0083] The network system based on the wireless bridge disclosed in the embodiments of the present application comprises a first wireless bridge device and a POP device, wherein the first wireless bridge device is internally provided with a user identification card of a 5G customized network, the POP device and the first wireless bridge device are configured with a fixed IP address in the 5G customized network; the first wireless bridge device is used for accessing the 5G customized network through a wireless signal; the POP device accesses the 5G customized network through a preset private line, and is used for establishing a 5G customized network private line connection between the first wireless bridge device and a target IP address, thereby replacing the optical cable with the 5G customized network private line, and forwarding data by taking the POP device as a convergence point, so as to solve the problem that once the transmission medium such as the optical cable fails, network communication cannot be performed in the prior art.
