[0043] The names of messages or information exchanged between multiple devices in the embodiments of this disclosure are for illustrative purposes only and are not intended to limit the scope of such messages or information.

[0044] In related technologies, communication services can be provided based on a fixed network. In this process, the service data sender can send service data to a network access device associated with the service data sender. The network access device accesses 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. The network access device of the service data receiver then sends the service data to the service data receiver. The network access device is used as an access device for the fixed network.

[0045] However, when a fault occurs in a fixed network, such as a network device failure or a fiber optic cable break, communication will be impossible, resulting in a decrease in the reliability of user communication based on the fixed network and affecting the user's communication experience.

[0046] Figure 1 A schematic diagram of a communication data transmission system according to an exemplary embodiment of this disclosure is shown. Figure 1As shown, the implementation scenario 100 includes a first wireless network access device 101, a first fixed network access device 102, a gateway device 103, and a second fixed network access device 104. The first wireless network access device 101 connects the terminal device or network device of the service data sender to the network. The first fixed network access device 102 can be a Customer Premise Equipment (CPE) in a fixed network, used to connect service data sent by the user terminal of the service data sender to the fixed network. The second fixed network access device 104 can be a CPE in a fixed network, used to send service data from the fixed network to the user terminal of the service data receiver. The gateway device 103 connects to the user plane function network element in the core network. Figure 1 (Not shown in the image) is connected to implement the communication data transmission scheme in the embodiments of this disclosure.

[0047] It should be noted that in real-world scenarios, in addition to wireless network access devices, network access equipment, and gateway devices, other devices may also be present. Wireless network access devices can include wireless base stations or communication satellites, such as... Figure 1 As shown, when the gateway device executes the communication data transmission scheme provided in this embodiment, upon receiving a service data transmission request from the first user terminal and determining that the fixed network accessed by the first network fixed access device is faulty, 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 user plane function network elements; furthermore, the gateway device 103 receives the service data sent by the user plane function network elements and sends the service data to the second user terminal connected to the second network fixed access device.

[0048] Figure 2 A flowchart illustrating an exemplary embodiment of the present disclosure is shown. This method can be applied to a gateway device connected to a user plane function network element, such as... Figure 2 As shown, the method in this embodiment of the disclosure may include:

[0049] Step S201: Receive service data sent by the user plane function network element;

[0050] The service data is sent by the first network fixed access device to the first wireless network access device when the first network fixed access device receives a service data transmission request from the first user terminal and determines that the fixed network to which the first network fixed access device is connected is faulty. The service data is then sent by the first wireless network access device to the core network, which includes user plane function network elements.

[0051] Step S202: Send the service data to the second user terminal connected to the second network fixed access device;

[0052] In summary, the communication data transmission method provided in this disclosure can send service data to a wireless network access device after the first fixed access device, which is the sender of service data, determines that the fixed network it accesses has failed, and then 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 function network element of the core network, it sends the service data to the second user terminal connected to the second fixed access device. This enables the transmission of service data via a wireless network in a fixed network communication scenario when the fixed network fails, thereby improving the reliability of service data transmission.

[0053] The following are Figure 2 The specific implementation methods of each step in the illustrated embodiment are described in detail below:

[0054] In step S201, the gateway device receives service data sent by the user plane function network element.

[0055] In the embodiments of this disclosure, the user plane function network element can be determined based on the architecture of the communication network, and this disclosure does not limit it in this regard. For example, if the communication network is a fourth-generation wireless cellular technology (4G) communication network, the user plane function network element may include the service gateway (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 the user data plane function (UPF) network element in the core network of the 5G communication network. The user plane function network element is used to access data traffic from the bearer network to the core network, or to distribute data traffic from the core network to the bearer network for forwarding to the user terminal.

[0056] It should be noted that, typically, during communication between the first user terminal and the second user terminal, to reduce communication costs, the first user terminal and the second user terminal can communicate based on a fixed network within the bearer network. Specifically, in the scenario where the first user terminal is the service data sender, 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 through the fixed network it accesses. Alternatively, the first network fixed access device can receive service data sent by the second user terminal through the fixed network it accesses and forward the service data to the first user terminal. Similarly, in the scenario where the second user terminal is the service data sender, 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 through the fixed network it accesses. Alternatively, the second network device can receive service data sent by the first user terminal through the fixed network it accesses and forward the service data to the second user terminal.

[0057] In one optional implementation, the present disclosure can be described using a scenario where the first user terminal is the service data sender as an example. In this scenario, when the first fixed network access device receives a service data transmission request from the first user terminal and determines that the fixed network to which the first fixed network access device is connected is faulty, it needs to send the service data to the first wireless network access device. The first wireless network access device then sends the service data to the core network, which includes user plane function network elements. The first wireless network access device can be the wireless network access device that is closest to the first fixed network access device.

[0058] In one optional implementation, 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 based on a wireless router, for example, the wireless user terminal sending the service data transmission request to the wireless router via a wireless link, and the wireless router sending the service data transmission request to the first network fixed access device via a wired link; or, the first user terminal sending the service data transmission request to the first network fixed access device based on a wired link, for example, a desktop computer sending 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 the service data transmission operation, based on the service data to be sent. The service data can be determined based on the current service scenario, and this embodiment of the disclosure does not limit this. For example, in a session scenario, the service data can be session content, such as session messages or video, etc.

[0059] In one optional implementation, the process by which the first network fixed access device determines whether the fixed network it accesses is faulty may include: acquiring transmission quality parameters of service data in the fixed network accessed by the first network fixed access device; when the transmission quality parameters are greater than a parameter threshold, the fixed network accessed by the first network fixed access device may be determined to be faulty. The transmission quality parameters of the service data may include parameters such as packet loss rate, jitter, and / or latency during the transmission of the service data, which are used to characterize the transmission quality of the service data. The parameter threshold may be determined based on actual needs, and this disclosure does not limit this.

[0060] In one alternative implementation, the network access device of the fixed network can typically 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 Protection (OMSP) mechanism, etc. The process by which the first fixed access device determines whether the fixed network to which it is connected is faulty can include: after the first fixed access device determines that the line protection mechanism in it has failed to execute, it can determine that the fixed network to which it is connected is faulty.

[0061] It should be noted that, in this embodiment of the disclosure, the process of the first fixed network access device sending service data to the first wireless network access device, and the first wireless network access device sending the service data to the core network, may include: the first fixed network access device can send the service data in the service data transmission request sent by the first user terminal to the first wireless network access device via a wireless link; the wireless network access device can send the service data to the core network based on the bearer network; wherein, the user plane function 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 this embodiment of the disclosure, the first fixed network access device can send an access request to the first wireless network access device through the wireless communication module in the first fixed network access device to pre-establish a wireless connection between the first fixed network access device and the first wireless network access device.

[0062] It should be noted that, in this embodiment of the disclosure, when service data needs to be transmitted over a wireless network, since the wireless network transmits packets based on the Internet Protocol (IP), while the fixed network transmits data through tags, in order to facilitate the transmission of service data over the wireless network, the service data can be encapsulated into IP packets for transmission. For example, the first network fixed access device can encapsulate the service data into a Generic Routing Encapsulation (GRE) packet and send the GRE packet to the core network; furthermore, the user plane function network element of the core network can forward the GRE packet to the gateway device.

[0063] In one optional implementation, after the user plane function network element of the core network sends service data to the gateway device, the gateway device can receive the service data sent by the user plane function network element. Optionally, the service data received by the gateway device can be a GRE message sent by the user plane function network element.

[0064] In step S202, the gateway device can send service data to the second user terminal connected to the second network fixed access device.

[0065] In this embodiment of the 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 this disclosure does not limit it. 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 Provider Edge (NPE) device.

[0066] It should be noted that, in this embodiment of the disclosure, for the second user terminal that is the recipient of the service data, the second user terminal can obtain service data from the fixed network accessed by the second network fixed access device. Under normal circumstances, the fixed network accessed by the second network fixed access device may also be faulty. 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.

[0067] In one optional implementation, the process of the gateway device sending service data to a second user terminal connected to the second network fixed access device may include: in the event of a failure in the fixed network accessed by the second network fixed access device, sending the service data to a user plane function network element, so that the user plane function network element sends the service data to a 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. Being able to send service data to the second user terminal connected to the second network fixed access device via a wireless network in the event of a failure in the fixed network accessed by the second network fixed access device can further improve the reliability of service data transmission.

[0068] In one optional implementation, the service data is a GRE packet encapsulated based on the Generic Routing Encapsulation (GRE) protocol. The process of sending the service data to a user plane function network element, which then forwards it to a second wireless network access device, and finally to a second fixed network access device, may include: sending a GRE packet to the user plane function network element, which then forwards it to the second wireless network access device, and finally to the second fixed network access device. It is understood that in this embodiment, a GRE tunnel can be established between devices capable of transmitting GRE packets to transmit GRE packets. Service data can be transmitted using IP packets recognizable by the wireless network to ensure the continued functionality of service data transmission even in the event of a fixed network failure, thereby improving the reliability of service data transmission.

[0069] It should be noted that, in this embodiment of the disclosure, the GRE messages received by the gateway device from the user plane function network element and the GRE messages sent by the gateway device to the user plane function network element are sent through different GREs.

[0070] In one optional implementation, the gateway device is also connected to a network-side core device. The process by which the gateway device sends service data to a second user terminal connected to the second network fixed access device may include: when the fixed network accessed by the second network fixed access device is functioning normally, 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. Alternatively, when the fixed network accessed by the second network fixed access device is functioning normally, the service data can be sent to the second user terminal connected to the second network fixed access device via the fixed network.

[0071] It should be noted that, in this embodiment of the disclosure, in order to achieve 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 act as a gateway network element device of a Data Communication Network (DCN). The gateway device can 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 include device configuration information, etc., which is not limited in this embodiment of the disclosure. The gateway device can be used to manage the first network fixed access device and / or the second network fixed access device, reducing the management complexity of network access devices.

[0072] Optionally, the gateway device can receive device management data of the first fixed access device sent by the network management system network element, and send the device management data of the first fixed access device to the first fixed access device; or, the gateway device can receive device management data of the second fixed access device sent by the network management system network element, and send the device management data of the second fixed access device to the second fixed access device, wherein the device management data may be device operation and maintenance data, etc.

[0073] It should be noted that, in this embodiment of the disclosure, after the first network fixed access device determines that the fixed network it accesses has recovered from a fault, it can disconnect from the first wireless network access device and transmit service data through the fixed network it accesses; similarly, after the second network fixed access device determines that the fixed network it accesses has recovered from a fault, it can disconnect from the second wireless network access device and receive service data through the fixed network it accesses.

[0074] The foregoing primarily describes the solutions provided by the embodiments of this disclosure from the perspective of a gateway device. It is understood that, in order to achieve the above functions, the gateway device includes corresponding hardware structures and / or software modules for executing each function. Those skilled in the art should readily recognize that, based on the units and algorithm steps of the various examples described in conjunction with the embodiments disclosed herein, this disclosure can be implemented in hardware or a combination of hardware and computer software. Whether a function is executed in hardware or by computer software driving hardware depends on the specific application and design constraints of the technical solution. Those skilled in the art can use different methods to implement the described functions for each specific application, but such implementation should not be considered beyond the scope of this disclosure.

[0075] Figure 3 A flowchart illustrating an exemplary embodiment of the present disclosure is shown. This method can be applied to a second network fixed access device, such as... Figure 3 As shown, the method in this embodiment of the disclosure may include:

[0076] Step S301: Receive service data sent by the gateway device;

[0077] The service data in the gateway device is sent by the first network fixed access device to the first wireless network access device when the first network fixed access device receives a service data transmission request sent by the first user terminal and determines that the fixed network accessed by the first network fixed access device is faulty. The first wireless network access device then sends the service data to the core network and then sends it to the gateway device through the user plane function network element of the core network.

[0078] Step S302: Send the service data to the second user terminal;

[0079] In summary, the communication data transmission method provided in this disclosure can send service data to a wireless network access device after the first fixed access device, which is the sender of service data, determines that the fixed network it accesses has failed, and then 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 function network element of the core network, it sends the service data to the second user terminal connected to the second fixed access device. This enables the transmission of service data via a wireless network in a fixed network communication scenario when the fixed network fails, thereby improving the transmission reliability of the service data received by the second user terminal.

[0080] It should be noted that, in this embodiment of the disclosure, the fixed network accessed by the second network fixed access device may be normal or faulty. In an optional implementation, the process of the second network fixed access device receiving service data sent by the gateway device may include: in the event of a fault in the fixed network accessed by the second network fixed access device, the gateway device sends 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.

[0081] In one optional implementation, the process of the second network fixed access device receiving 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.

[0082] This disclosure embodiment can divide the gateway device into functional units according to the above method example. For example, it can divide each function into a separate functional module, or it can integrate two or more functions into one processing module. The integrated module can be implemented in hardware or as a software functional module. It should be noted that the module division in this disclosure embodiment is illustrative and only represents one logical functional division. In actual implementation, there may be other division methods.

[0083] By dividing each functional module according to its corresponding function, an exemplary embodiment of this disclosure provides a communication data transmission device, which can be a gateway device or a chip applied to a gateway device. Figure 4 A schematic block diagram of the functional modules of a communication data transmission apparatus according to an exemplary embodiment of the present disclosure is shown. The communication data transmission apparatus is a gateway device, which is connected to a user plane function network element. Figure 4 As shown, the communication data transmission device 400 includes:

[0084] The first receiving module 401 is configured to receive service data sent by the user plane function network element. The service data is sent by the first network fixed access device to the first wireless network access device when the first network fixed access device receives a service data transmission request sent by the first user terminal and determines that the fixed network accessed by the first network fixed access device is faulty. The first wireless network access device then sends the service data to the core network, and the core network includes the user plane function network element.

[0085] The first sending module 402 is configured to send the service data to a second user terminal connected to a second network fixed access device.

[0086] Optionally, the first sending module 402 is configured to:

[0088] Optionally, the service data is a GRE message encapsulated based on the Generic Routing Encapsulation (GRE) protocol, and the first sending module 402 is configured to:

[0089] The GRE message is sent to the user plane function network element, so that the user plane function 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.

[0090] Optionally, the first sending module 402 is configured to:

[0091] When the fixed network accessed by the second fixed access device is normal, the service data is sent to the network-side core device, so that the network-side core device sends the service data to the second fixed access device based on the fixed network accessed by the second fixed access device, and the second fixed access device sends the service data to the second user terminal.

[0092] Optionally, the device further includes a third receiving module 403, configured to:

[0093] Receive device management data sent by the first network fixed access device or the second network fixed access device;

[0094] The device management data is sent to the network management system network element.

[0095] This disclosure embodiment can divide the second network fixed access device into functional units according to the above method example. For example, it can divide each function into a separate functional module, or it can integrate two or more functions into one processing module. The integrated module can be implemented in hardware or as a software functional module. It should be noted that the module division in this disclosure embodiment is illustrative and only represents one logical functional division. In actual implementation, there may be other division methods.
