[0058] The present invention mainly solves the problem of insufficient reliability of voice services in the prior art, where voice interruptions often occur due to various reasons such as the uplink channel being damaged by external forces, and it is difficult to repair, thus unable to meet customer needs. Based on the current voice services in use, a multi-service protection method is adopted to increase uplink protection redundancy. Multiple protocols and multiple ports are used for access, and multiple-channel routing is provided for uplink connection to protect voice services diversely, reducing the probability of voice services being damaged, thereby improving the end-to-end reliability performance of customer voice services and providing a service that meets the customer's voice robustness requirements. In addition, a wireless-wired integration technology is also used to provide customer voice services. The 5G UPF is utilized to provide network slice dedicated line services to achieve fixed-mobile integration, combining the advantages of strong anti-interference ability of wired networks with the flexible layout advantages of 5G wireless networks, and providing a seamless, end-to-end voice service for customers, protecting customer voice services comprehensively in an air-land integrated manner.

[0059] As Figure 1 shown in the following is a flowchart of the steps of a multi-channel protection method for voice services based on fixed-mobile integration provided by an embodiment of the present invention. Referring to Figure 1 , an embodiment of the present invention provides a multi-channel protection method for voice services based on fixed-mobile integration, which specifically includes the following steps:

[0060] S101. Connect the customer-side voice device and the core network-side device through a fixed-mobile multi-channel fusion gateway, and establish a primary wired channel, a secondary wired channel, and a standby 5G channel between the fixed-mobile multi-channel fusion gateway and the core network-side device;

[0061] S102. Carry the voice service between the customer-side voice device and the core network-side device through the primary wired channel, and monitor the availability of the primary wired channel and the secondary wired channel in real time;

[0062] S103. When the primary wired channel is interrupted and the secondary wired channel remains connected, switch the voice service to the secondary wired channel through the fixed-mobile multi-channel fusion gateway;

[0063] S104. When both the primary wired channel and the secondary wired channel are interrupted, switch the voice service to the standby 5G channel through the fixed-mobile multi-channel fusion gateway.

[0064] As Figure 2The figure shows a networking schematic diagram of the primary wired channel, secondary wired channel, and backup 5G channel provided by the embodiments of the present invention. Based on multi-channel uplink and multi-port access, the embodiments of the present invention enhance the uplink protection mechanism. By using a fixed-mobile multi-channel fusion gateway and combining wired and 5G wireless, diverse protection for services is achieved, realizing high reliability of services. The feasible service protection methods are implemented through the service system architecture, which consists of a fixed-mobile multi-channel fusion gateway and the primary wired service access module, secondary wired service access module, and 5G wireless access module deployed on this gateway. It can achieve reliable processing of services, realize customer service protection, provide end-to-end voice services with high robustness performance through the fixed-mobile fusion of wired and 5G wireless, make the voice services have security and reliability, and can be realized by using the existing network resources, being easy to expand and maintain.

[0065] In the embodiments of the present invention, a fixed-mobile multi-channel fusion gateway is deployed on the customer side, and the primary wired channel, secondary wired channel, and backup 5G channel between the fixed-mobile multi-channel fusion gateway and the core network side equipment are constructed. Through the primary wired channel, secondary wired channel, and backup 5G channel, multi-level protection is carried out on the voice service between the customer side voice device and the core network side device, ensuring the normal operation of the voice service, improving the reliability of the voice service and the user's voice service usage experience.

[0066] As Figure 3 shown is a step flowchart of step S101 provided by the embodiments of the present invention. Referring to Figure 3 , further as an optional implementation manner, the primary wired channel, secondary wired channel, and backup 5G channel between the fixed-mobile multi-channel fusion gateway and the core network side equipment are established, which specifically includes:

[0067] S1011: Connect the primary wired service access module of the fixed-mobile multi-channel fusion gateway to the PON network and then to the core network side equipment to establish the primary wired channel;

[0068] S1012: Connect the secondary wired service access module of the fixed-mobile multi-channel fusion gateway to the core network side equipment through fiber direct drive and an optical modem to establish the secondary wired channel;

[0069] S1013: Connect the 5G wireless access module of the fixed-mobile multi-channel fusion gateway to the core network side equipment through the 5G network slice dedicated line provided by 5G UPF to establish the backup 5G channel.

[0070] Specifically, a fixed-mobile multi-channel converged gateway is arranged in the customer-side computer room, and different access modules are configured. The core network is accessed through the existing PON network, optical fiber direct access, 5G wireless access, etc., and the channel availability is checked in real time. The SIP protocol is used to achieve multi-routing and fixed-mobile uplink. The main wired service access module is used to access the PON network to connect to the core-side equipment, and the advantages of the PON network's wide networking and strong protection capabilities are used for voice transmission, and the main wired channel ( Figure 2 The secondary wired service access module is connected to the core side equipment through optical fiber direct drive + optical modem, serving as the secondary wired channel ( Figure 2 Middle channel 2), in the event of a failure in the primary wired channel, the secondary wired channel is used for data transmission, and the fast installation characteristics of optical fiber direct drive can be used to achieve rapid service release; the 5G wireless access module is flexibly arranged, and the network slicing dedicated line and QoS provided by 5G UPF are used as the means and functions of new voice dedicated line quality assurance to provide customers with 5G wireless access dedicated lines, connect customer voice equipment with the core network, and establish a backup 5G channel ( Figure 2 In channel 3), 5G UPF provides sliced ​​private line services and serves as the interconnection point between the fixed-mobile convergence gateway and the large network. It completes the encapsulation and decapsulation of the GTP protocol and opens up the connection between the fixed-mobile convergence gateway and the large network.

[0071] It can be appreciated that the fixed-mobile multi-channel converged gateway of the embodiment of the present invention is inserted in series between the client and the existing network, accesses the existing PON, optical fiber network and wireless network, does not change the existing network networking mode, is easy to maintain, and provides reliable services.

[0072] like Figure 4 FIG. 1 is a flow chart of step S102 provided in an embodiment of the present invention, referring to FIG. Figure 4 As an optional implementation, real-time monitoring of the availability of the primary wired channel and the secondary wired channel may include:

[0073] S1021. Configure a primary uplink interface corresponding to a primary wired service access module and a secondary uplink interface corresponding to a secondary wired service access module on the fixed-mobile multi-channel converged gateway;

[0074] S1022, performing multi-port service status detection on the primary uplink interface and the secondary uplink interface, and obtaining the port status and heartbeat information of the primary uplink interface and the secondary uplink interface respectively;

[0075] S1023, when the port of the primary uplink interface is in the down state or the heartbeat information is abnormal, it is determined that the primary wired channel is interrupted;

[0076] S1024: When the port of the secondary uplink interface is in a down state or the heartbeat information is abnormal, it is determined that the secondary wired channel is interrupted.

[0077] As Figure 5 shown, it is a flowchart of a step of step S103 provided by an embodiment of the present invention. Referring to Figure 5 , further as an optional implementation manner, when the primary wired channel is interrupted and the secondary wired channel remains connected, the voice service is switched to the secondary wired channel through the fixed-mobile multi-channel fusion gateway. Specifically:

[0078] S1031. When the primary wired channel is interrupted and the secondary wired channel remains connected for a preset duration, the data packets sent by the customer-side voice device are distributed to the secondary upstream interface through the service processing module of the fixed-mobile multi-channel fusion gateway, and the data packets returned by the core network-side device are received through the secondary upstream interface.

[0079] Specifically, the FMMG (fixed-mobile multi-channel fusion gateway) service system configures multi-type interface units, and each interface unit provides an upstream interface. The interface enables the MSSD protection mode. Under normal circumstances, the interfaces are all open. Whether to perform switching is determined by detecting the port status and heartbeat information. When the port of the primary upstream interface fails or normal heartbeat information cannot be received, after detection by the service processing module, the secondary upstream interface is automatically detected. If the secondary upstream interface is normal and data synchronization is normal, the system switches to the secondary wired access module, automatically switches the service to the standby upstream route, and keeps detecting the port status to achieve service protection switching and service recovery, improving service security.

[0080] As Figure 6 shown, it is another flowchart of a step of the voice service multi-channel protection method based on fixed-mobile fusion provided by an embodiment of the present invention. Referring to Figure 6 , further as an optional implementation manner, the service processing module includes a primary service processing module and a standby service processing module. The voice service multi-channel protection method further includes the following steps:

[0081] S105. When the primary service processing module fails, the data packets sent by the customer-side voice device and the data packets returned by the core network-side device are distributed through the standby service processing module.

[0082] Specifically, the FMMG (fixed-mobile multi-channel fusion gateway) configures a dual service processing module. When the primary service processing module fails, the service can be automatically switched to the standby service processing module. The primary and standby processing modules are in hot standby to ensure that the service can still run normally after a single module fails; in addition, the service system configures multiple power modules to ensure that when the primary power module fails, the standby power module takes over the work of the primary power module to ensure the normal operation of the service system.

[0083] In some optional embodiments, the FMMG (Fixed-Mobile Multi-Channel Fusion Gateway) is configured with a wired access module, which accesses the metropolitan area network MSE through methods such as PON network, fiber direct drive + optical MODEM, connects to the fixed-line core network using the SIP protocol, and ensures transmission quality and realizes service isolation by configuring QoS policies, link aggregation LACP, VPN, etc. The primary wired line and the secondary wired line are required to take different routes, in different trenches and cables, so that the interruption of one optical cable will not cause the simultaneous interruption of the two primary and secondary wired lines, further improving the service security performance.

[0084] Further as an optional implementation manner, a standby 5G channel is established between the 5G wireless access module and the core network side device through a dedicated VLAN and a dedicated interface. User isolation is performed between the fixed-mobile multi-channel fusion gateway and the 5G UPF through a GTP tunnel, and traffic between different customers is isolated through different DNNs.

[0085] Specifically, the fixed-mobile fusion gateway is configured with a wireless access module, which accesses the 5G UPF in the 5G network through the wireless network and the SDN network. The 5G UPF network slice and QoS are used as quality guarantee means, and access to the MSE is achieved through the UPF, connecting the customer device and the core network channel to ensure the normal operation of the service. The 5G core network uses a dedicated slice dedicated line for voice protection, allocates dedicated 5G service cards, and isolates access between 5G cards at the core layer. At the same time, a dedicated VLAN and a dedicated interface are used between the fixed-mobile multi-channel fusion gateway and the large network device to establish a dedicated voice protection route (i.e., a standby 5G channel) to transmit voice to the core network. User isolation is performed between the fixed-mobile multi-channel fusion gateway and the UPF through a GTP tunnel, and traffic between different customers is isolated using different DNNs. Each user is differentiated and isolated by an independent VLAN between the fixed-mobile fusion gateway and the UPF.

[0086] As Figure 7 shown is another step flow chart of step S104 provided by the embodiment of the present invention. Referring to Figure 7 , further as an optional implementation manner, when both the primary wired channel and the secondary wired channel are interrupted, the voice service is switched to the standby 5G channel through the fixed-mobile multi-channel fusion gateway. Specifically:

[0087] S1041. When both the primary wired channel and the secondary wired channel are interrupted, the data packets sent by the customer-side voice device are distributed to the dedicated interface through the service processing module of the fixed-mobile multi-channel fusion gateway, and the data packets returned by the core network side device are received through the dedicated interface.

[0088] Specifically, the fixed-mobile multi-channel fusion gateway device monitors the connectivity of the wired network channel from the device to the core network in real time. When the fusion gateway device fails to detect the heartbeat of the fixed network and detects an abnormality in the wired network channel, it intelligently switches to protection and automatically switches the service to the 5G wireless channel for transmission, that is Figure 2 Channel 3 in Figure 2 . The voice is registered to the IMS core network through the 5G channel to restore the voice service. After the wired channel returns to normal, the service is automatically switched back to the wired channel to protect the service stability.

[0089] It should also be noted that the fixed-mobile fusion gateway device is configured with wired interfaces and wireless interfaces, and can preferentially select the wired channel or the wireless channel to transmit services according to needs, and keep in touch with the core network side in real time to send service life online detection. When it is detected that both the primary and backup links of the wired channel fail and the service is unavailable, the customer service is transmitted through the 5G wireless network to complete the signaling interaction, ensuring the normal operation of the customer service, thereby improving the stability of the customer service.

[0090] The method steps of the embodiments of the present invention are described above. It can be recognized that the embodiments of the present invention adopt the fixed-mobile fusion technology, which can provide a voice service that can be used by customers and whose service reliability is at least 50% higher than that of the existing service. It has the characteristics of high service guarantee, flexible deployment, and convenient installation, provides customers with a product service of seamless switching to the 5G backup line, and is applicable to various customer demand application scenarios with high requirements for service guarantee, difficult customer equipment wiring, and frequent mobility.

[0091] The embodiments of the present invention adopt a variety of transmission media, which can solve the defect of the single transmission medium of the traditional voice networking. It can use both wired transmission and 5G mobile wireless network to transmit services, with wide applicability. It can be used for customers who temporarily require emergency service activation, and is also applicable to customers who require long-term stable operation of services; by adopting the multi-port service status detection function, the uplink protection redundancy is improved, and through various service protection methods, the reliability requirements of end-to-end services can be enhanced.

[0092] The embodiments of the present invention adopt the wireless-wired fusion technology to provide customers with voice services. It can integrate the advantages of mature PON networking, fast fiber direct drive installation, and flexible wireless networking without wiring, combine the strong anti-interference ability of wired with the flexibility of the 5G wireless network, and provide customers with a seamless and end-to-end reliable service, solve the problem of unavailable voice services caused by damaged routes commonly seen at present, provide all-round protection in the air and on land, and enhance the stability of voice services for customers, especially government and enterprise customers.

[0093] In the embodiments of the present invention, a wired network is combined with a 5G wireless network.
