[0031] In related technologies, communication services can be provided to users based on a fixed network, wherein the service data sender can send the service data to a network access device associated with the service data sender, and the network access device connects the service data to be transmitted to the fixed network, and transmits the communication data to the network access device of the service data receiver through the fixed network, and the network access device of the service data receiver sends the service data to the service data receiver, wherein the network access device is an access device for the fixed network.

[0032] However, if a fault occurs in the fixed network, such as a failure of network equipment or a break in an optical fiber, communication may be impossible, resulting in poor reliability of user communications based on the fixed network and affecting the user's communication experience.

[0033] Figure 1 shows a schematic diagram of a communication data transmission system according to an exemplary embodiment of the present disclosure. As shown in Figure 1, the implementation scenario 100 includes a first wireless network access device 101, a first network fixed access device 102, a gateway device 103, and a second network fixed access device 104. The first wireless network access device 101 is used to connect a terminal device or network device serving as a service data sender to a network. The first network fixed access device 102 can be a customer premises equipment (CPE) in a fixed network, used to connect service data sent by a user terminal serving as a service data sender to the fixed network. The second network fixed access device 104 can be a CPE in a fixed network, used to send service data from the fixed network to a user terminal serving as a service data receiver. The gateway device 103 is used to connect to a user plane functional network element (not shown in Figure 1) in the core network to implement the communication data transmission solution in the embodiment of the present disclosure.

[0034] It should be noted that in actual scenarios, in addition to wireless network access devices, network access devices, and gateway devices, other devices may also be present. Wireless network access devices may include wireless base stations or communication satellites, etc. As shown in FIG1 , when the gateway device executes the communication data transmission solution provided by the embodiment of the present disclosure, upon receiving a service data transmission request sent by a first user terminal and determining that the fixed network to which the first network fixed access device is connected has failed, the first network fixed access device 102 sends the service data to the first wireless network access device 101, and the first wireless network access device 101 sends the service data to the core network, which includes a user plane functional network element. Furthermore, the gateway device 103 receives the service data sent by the user plane functional network element and sends the service data to a second user terminal connected to a second network fixed access device.

[0035] FIG2 shows a flowchart of a communication data transmission method according to an exemplary embodiment of the present disclosure. The method may be applied to a gateway device connected to a user plane function network element. As shown in FIG2 , the method according to the embodiment of the present disclosure may include:

[0036] Step S201: receiving service data sent by a user plane functional network element.

[0037] When the first network fixed access device receives a service data sending request sent by the first user terminal and determines that the fixed network accessed by the first network fixed access device fails, the first network fixed access device sends the service data to the first wireless network access device, and the first wireless network access device sends the service data to the core network, which includes a user plane functional network element.

[0038] Step S202: Send the service data to a second user terminal connected to the second network fixed access device.

[0039] In summary, in the communication data transmission method provided in the embodiments of the present disclosure, after a first network fixed access device associated with the service data sender determines that the fixed network to which the first network fixed access device is connected has failed, the service data can be sent to a wireless network access device, which in turn causes the wireless network access device to send the service data to the core network. Furthermore, after obtaining the service data from the user plane functional network element of the core network, the gateway device sends the service data to a second user terminal connected to a second network fixed access device. This enables service data to be transmitted via the wireless network in fixed network communication scenarios in the event of a fixed network failure, thereby improving the reliability of service data transmission.

[0040] The specific implementation of each step in the embodiment shown in Figure 2 is described in detail below:

[0041] In step S201, the gateway device receives service data sent by the user plane functional network element.

[0042] In the embodiment of the present disclosure, the user plane function network element can be determined based on the architecture of the communication network, and the embodiment of the present disclosure does not limit this. For example, if the communication network is a fourth-generation wireless cellular technology (4G) communication network, the user plane function network element may include a service gateway (Serving Gate Way, SGW) in the core network of the 4G communication network. If the communication network is a fifth-generation wireless cellular technology (5G) communication network, the user plane function network element may include a user data plane function UPF (User Plane Function) network element in the core network of the 5G communication network. The user plane function network element is used to connect data traffic from the bearer network to the core network, or to send data traffic from the core network to the bearer network and then forward it to the user terminal.

[0043] It should be noted that, generally, in the communication process between a first user terminal and a second user terminal, in order to reduce communication costs, the first user terminal and the second user terminal can communicate based on a fixed network in the bearer network. In the scenario where the first user terminal acts as the sender of service data, the first network fixed access device can receive service data from the first user terminal and send the service data to the second user terminal via the fixed network to which the first network fixed access device accesses. Alternatively, the first network fixed access device can receive service data sent by the second user terminal via the fixed network to which the first network fixed access device accesses, and forward the service data to the first user terminal. Similarly, in the scenario where the second user terminal acts as the sender of service data, the second network fixed access device can receive service data from the second user terminal and send the service data to the first user terminal via the fixed network to which the second network fixed access device accesses. Alternatively, the second network device can receive service data sent by the first user terminal via the fixed network to which the first network fixed access device accesses, and forward the service data to the second user terminal.

[0044] In an optional implementation, the present disclosure may be described using a scenario where a first user terminal is used as a sender of service data as an example. When a first network fixed access device receives a service data sending request sent by the first user terminal and determines that a fixed network accessed by the first network fixed access device has failed, the first network fixed access device needs to send the service data to a first wireless network access device, and the first wireless network access device sends the service data to a core network, which includes a user plane functional network element. The first wireless network access device may be the wireless network access device that is closest to the first network fixed access device.

[0045] In an optional embodiment, the process of the first user terminal sending a service data transmission request to the first network fixed access device may include: the first user terminal sending the service data transmission request to the first network fixed access device via a wireless routing device. For example, the wireless user terminal sends the service data transmission request to the wireless routing device via a wireless link, and the wireless routing device sends the service data transmission request to the first network fixed access device via a wired link. Alternatively, the first user terminal sends the service data transmission request to the first network fixed access device via a wired link. For example, a desktop computer sends the service data transmission request to the first network fixed access device via a wired link. It is understood that the service data transmission request is generated by the first user terminal in response to a service data transmission operation and based on the service data to be transmitted. The service data may be determined based on the current service scenario, which is not limited in this embodiment of the present disclosure. For example, in a conversation scenario, the service data may be conversation content, such as conversation messages or videos.

[0046] In an optional embodiment, the process of the first network fixed access device determining whether the fixed network to which the first network fixed access device accesses has a fault may include: obtaining a transmission quality parameter of the service data in the fixed network to which the first network fixed access device accesses. When the transmission quality parameter is greater than a parameter threshold, it can be determined that the fixed network to which the first network fixed access device accesses has a fault. The transmission quality parameter of the service data may include parameters such as the packet loss rate, jitter and / or delay of the service data during transmission, which are used to characterize the transmission quality of the service data. The parameter threshold can be determined based on actual needs, and the embodiments of the present disclosure are not limited to this.

[0047] In an optional implementation, a network access device of the fixed network may generally be configured with a line protection mechanism, such as an Automatic Protection Switching (APS) mechanism, an Optical Line Protection (OLP) mechanism, or an Optical Multiplex Section Protect (OMSP), etc. The process of the first network fixed access device determining whether a fault has occurred in the fixed network to which the first network fixed access device accesses may include: after the first network fixed access device determines that the line protection mechanism in the first network fixed access device has failed to execute, determining that a fault has occurred in the fixed network to which the first network fixed access device accesses.

[0048] It should be noted that, in the embodiment of the present disclosure, the process in which the first network fixed access device sends service data to the first wireless network access device, and the first wireless network access device sends the service data to the core network may include: the first network fixed access device may send the service data carried in the service data sending request sent by the first user terminal to the first wireless network access device via a wireless link, and the first wireless network access device may send the service data to the core network based on the bearer network; wherein the user plane functional network element of the core network is used to forward the service data to the gateway device, so that the gateway device can forward the service data to the second user terminal. It should be noted that, in the embodiment of the present disclosure, the first network fixed access device may send an access request to the first wireless network access device through the wireless communication module in the first network fixed access device to pre-establish a wireless connection between the first network fixed access device and the first wireless network access device.

[0049] It should be noted that in the embodiments of the present disclosure, when service data needs to be transmitted over a wireless network, since wireless networks transmit messages based on the Internet Protocol (IP), while fixed networks transmit data through labels, in order to facilitate the transmission of service data over the wireless network, the service data can be encapsulated as IP messages for transmission. For example, the first network fixed access device can encapsulate the service data into a Generic Routing Encapsulation (GRE) message and send the GRE message to the core network. Furthermore, the user plane functional network element of the core network can forward the GRE message to the gateway device.

[0050] In an optional implementation, after the user plane functional network element of the core network sends the service data to the gateway device, the gateway device can receive the service data sent by the user plane functional network element. Optionally, the service data received by the gateway device can be a GRE message sent by the user plane functional network element.

[0051] In step S202, the gateway device may send the service data to the second user terminal connected to the second network fixed access device.

[0052] In the embodiment of the present disclosure, the network side core device is a core layer device of the bearer network. The network side core device can be determined based on the architecture of the communication network, and the present disclosure does not limit this. For example, if the communication network is a 4G communication network and the bearer network of the 4G communication network is a packet transport network (PTN), then the network side core device can be an L3 PTN landing device or an L3 PTN scheduling device. If the communication network is a 5G communication network and the bearer network of the 5G communication network is a slicing packet network (SPN), then the network side core device can be a network side operator edge (Network Provider Edge) NPE device.

[0053] It should be noted that in the embodiments of the present disclosure, for a second user terminal serving as a service data receiver, the second user terminal can obtain service data from the fixed network to which the second network fixed access device is connected, based on the second network fixed access device. Typically, the fixed network to which the second network fixed access device is connected may experience a failure. Therefore, the second network fixed access device can send a connection request to the second wireless network access device to establish a wireless connection between the second network fixed access device and the second wireless network access device.

[0054] In an optional embodiment, the process of the gateway device sending service data to the second user terminal connected to the second network fixed access device may include: in the event that the fixed network accessed by the second network fixed access device fails, sending the service data to the user plane function network element, so that the user plane function network element sends the service data to the second wireless network access device, and the second wireless network access device sends the service data to the second network fixed access device, and the second network fixed access device sends the service data to the second user terminal. In this way, the present disclosure can send service data to the second user terminal connected to the second network fixed access device via the wireless network when the fixed network accessed by the second network fixed access device fails, which can further improve the transmission reliability of the service data.

[0055] In an optional embodiment, the service data is a GRE message encapsulated based on the Generic Routing Encapsulation (GRE) protocol. The process of sending the service data to the user plane functional network element so that the user plane functional network element sends the service data to the second wireless network access device, and the second wireless network access device sends the service data to the second network fixed access device may include: sending the GRE message to the user plane functional network element so that the user plane functional network element sends the GRE message to the second wireless network access device, and the second wireless network access device sends the GRE message to the second network fixed access device. It is understood that in the embodiment of the present disclosure, a GRE tunnel can be established between devices capable of transmitting GRE messages to transmit GRE messages through the GRE tunnel between the devices. Service data can be transmitted via a wireless network using identifiable IP messages to ensure that the function of transmitting service data via the wireless network is implemented in the event of a fixed network failure, thereby improving the transmission reliability of service data.

[0056] It should be noted that, in the embodiment of the present disclosure, the GRE message sent by the user plane function network element and received by the gateway device, and the GRE message sent by the gateway device to the user plane function network element are sent through different GREs.

[0057] In an optional embodiment, the gateway device is further connected to a network-side core device, and the process of the gateway device sending service data to a second user terminal connected to a second network fixed access device may include: when the fixed network accessed by the second network fixed access device is normal, sending the service data to the network-side core device, so that the network-side core device sends the service data to the second network fixed access device based on the fixed network accessed by the second network fixed access device, and the second network fixed access device sends the service data to the second user terminal. When the fixed network accessed by the second network fixed access device is normal, the service data can be sent to the second user terminal connected to the second network fixed access device via the fixed network.

[0058] It should be noted that in the embodiments of the present disclosure, in order to implement device management of the first network fixed access device and the second network fixed access device, the gateway device can be connected to a network management system (NMS) network element. The gateway device can serve as a gateway network element device of a data communication network (DCN). The gateway device can then receive device management data sent by the first network fixed access device or the second network fixed access device and send the device management data to the network management system network element. The device management data can be device configuration information, etc., which is not limited in the embodiments of the present disclosure. The first network fixed access device and / or the second network fixed access device can be managed through the gateway device, reducing the management complexity of the network access devices.

[0059] Optionally, the gateway device can receive device management data of a first network fixed access device sent by a network management system network element, and send the device management data of the first network fixed access device to the first network fixed access device; or, the gateway device can receive device management data of a second network fixed access device sent by a network management system network element, and send the device management data of the second network fixed access device to the second network fixed access device, wherein the device management data may be device operation and maintenance data, etc.

[0060] It should be noted that in the embodiments of the present disclosure, after the first network fixed access device determines that the fixed network to which the first network fixed access device is connected has returned to normal (i.e., the fault has been repaired), it can disconnect from the first wireless network access device and transmit service data through the fixed network to which the first network fixed access device is connected. Similarly, after the second network fixed access device determines that the fixed network to which the second network fixed access device is connected has returned to normal, it can disconnect from the second wireless network access device and receive service data through the fixed network to which the second network fixed access device is connected.

[0061] The above mainly introduces the solution provided by the embodiment of the present disclosure from the perspective of the gateway device. It can be understood that in order to realize the above functions, the gateway device includes hardware structures and / or software modules corresponding to the execution of each function. Those skilled in the art should easily realize that, in combination with the units and algorithm steps of each example described in the embodiments disclosed herein, the present disclosure can be implemented in the form of hardware or a combination of hardware and computer software. Whether a function is executed in a hardware or computer software-driven hardware manner depends on the specific application and design constraints of the technical solution. Professional and technical personnel can use different methods to implement the described functions for each specific application, but such implementation should not be considered to exceed the scope of this disclosure.

[0062] FIG3 shows a flowchart of a communication data transmission method according to an exemplary embodiment of the present disclosure. The method may be applied to a second network fixed access device. As shown in FIG3 , the method according to the exemplary embodiment of the present disclosure may include the following steps 301 - 302 .

[0063] Step S301: receiving service data sent by a gateway device.

[0064] In which, when the first network fixed access device receives a service data sending request sent by the first user terminal and determines that the fixed network accessed by the first network fixed access device fails, the first network fixed access device sends the service data to the first wireless network access device, and after the first wireless network access device sends the service data to the core network, the service data is sent to the gateway device through the user plane function network element of the core network.

[0065] Step S302: Send the service data to the second user terminal.

[0066] In summary, the communication data transmission method provided by the embodiments of the present disclosure can, after a first network fixed access device, acting as the sender of service data, determines that the fixed network to which the first network fixed access device is connected has failed, send the service data to a wireless network access device, and cause the wireless network access device to send the service data to the core network. Furthermore, after the gateway device obtains the service data from the user plane functional network element of the core network, it sends the service data to a second user terminal connected to a second network fixed access device. In this way, in a fixed network communication scenario, service data can be transmitted via the wireless network in the event of a fixed network failure, thereby improving the transmission reliability of the service data received by the second user terminal.

[0067] It should be noted that in the embodiment of the present disclosure, the fixed network to which the second network fixed access device accesses may be normal or malfunction. In an optional implementation, the process of the second network fixed access device receiving the service data sent by the gateway device may include: when the fixed network to which the second network fixed access device accesses fails, the gateway device sends the service data to the user plane function network element in the core network, so that the user plane function network element sends the service data to the second wireless network access device.

[0068] In an optional embodiment, the process of the second network fixed access device receiving the service data sent by the gateway device may include: when the fixed network accessed by the second network fixed access device is normal, the gateway device sends the service data to the network side core device, so that the network side core device sends the service data to the second network fixed access device based on the fixed network accessed by the second network fixed access device.

[0069] The embodiments of the present disclosure can divide the functional units of the gateway device according to the above method examples. For example, each functional module can be divided according to each function, or two or more functions can be integrated into one processing module. The above integrated modules can be implemented in the form of hardware or in the form of software functional modules. It should be noted that the division of modules in the embodiments of the present disclosure is schematic and is only a logical functional division. In actual implementation, there may be other division methods.

[0070] In the case of dividing functional modules according to their respective functions, the exemplary embodiments of the present disclosure provide a communication data transmission device, which can be included in a gateway device or a chip applied to a gateway device. Figure 4 shows a schematic block diagram of the functional modules of the communication data transmission device according to the exemplary embodiments of the present disclosure. The communication data transmission device is included in the gateway device, and the gateway device is connected to the user plane functional network element. As shown in Figure 4, the communication data transmission device 400 includes a first receiving module 401 and a first sending module 402.

[0071] The first receiving module 401 is configured to receive service data sent by the user plane functional network element, wherein, when the first network fixed access device receives a service data sending request sent by the first user terminal and determines that the fixed network accessed by the first network fixed access device fails, the first network fixed access device sends the service data to the first wireless network access device, and the first wireless network access device sends the service data to the core network, and the core network includes the user plane functional network element.

[0072] The first sending module 402 is configured to send the service data to a second user terminal connected to the second network fixed access device.
