Technical Field

[0001] This application relates to the field of data transmission technology, and in particular to a control method, device, storage medium, and program product for voice services. Background Technology

[0002] In corporate voice leased line services, clients often use transmission equipment such as Optical Network Unit (ONU), Packet Transport Network (PTN), or Optical Transport Network (OTN) as access devices.

[0003] In related technologies, high-capacity PTN transmission equipment is deployed on the client side, and primary and backup service paths are established through the PTN metropolitan area network and the voice core network's language platform. In this technical solution, both the primary and backup service paths consist of the client-side PTN equipment, the PTN metropolitan area network, and the voice core network's language platform. Since the primary and backup services share the same physical access optical cable on the client side, when the access optical cable fails, both the primary and backup service paths will be interrupted simultaneously, resulting in low reliability.

[0024] To make the objectives, technical solutions, and advantages of this application more apparent, exemplary embodiments according to this application will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this application, and not all embodiments of this application. It should be understood that this application is not limited to the exemplary embodiments described herein.

[0025] See Figure 1 A voice service control method is applied to a customer premises equipment 101. The customer premises equipment 101 includes a first access interface and a second access interface. The first access interface is used to access a wired network as an access point for a first path from a bearer network 102 to a voice platform 103. The second access interface is used to access a wireless network as an access point for a second path from a wireless access network 104, a user plane function 105 of a wireless core network, and a bearer network 102 to a voice platform 103.

[0026] See Figure 2 A method for controlling voice services, comprising: S201, control the transmission of voice service data through the first access interface, so that the voice service data is transmitted to the voice platform through the first path.

[0027] In this step, the customer's premises equipment sends voice service data through the first access interface via a wired network, enabling the voice service data to be forwarded to the voice platform via the bearer network, thereby achieving normal transmission of voice services.

[0028] S202, Detect the connectivity of the first path.

[0029] In this step, the customer's premises equipment can detect the connectivity status of the first path to determine whether the path is available. Connectivity detection is used to reflect the reachability of voice service data for end-to-end transmission via the first path.

[0030] Connectivity detection can be achieved by sending test messages and determining whether a response is received. For example, the first path can be periodically detected based on a path connectivity detection mechanism. This application does not limit the scope of this embodiment.

[0031] S203, when an abnormality in the connectivity of the first path is detected, the voice service data is switched to be transmitted via the second access interface, so that the voice service data is transmitted to the voice platform through the second path.

[0032] In this step, when a connectivity anomaly is detected in the first path, the customer premises equipment can stop sending voice service data through the first access interface and instead send the voice service data through the second access interface via the wireless network. This allows the voice service data to be transmitted to the voice platform sequentially via the wireless access network, the user plane function of the wireless core network, and the bearer network, thereby reducing the probability of voice service interruption.

[0033] In the technical solution of this application embodiment, according to the voice service control method of this application embodiment, a first access interface and a second access interface are set in the customer premises equipment, which serve as the access points for the first path of accessing the voice platform via a wired network and the second path of accessing the voice platform via a wireless network, respectively. During the transmission of voice service data via the first path, the connectivity of the first path is detected, and when a connectivity abnormality is detected in the first path, the voice service data is switched to the second path, that is, transmitted to the voice platform sequentially via the wireless access network, the user plane function of the wireless core network, and the bearer network, thereby reducing the probability of voice service interruption and improving the reliability of voice service data transmission.

[0034] See Figure 3In one example, the voice service control method is applied to Customer Premises Equipment (CPE). The CPE communicates with the voice platform via the CPE. The bearer network 102 can be a Slicing Packet Network (SPN), the voice platform 103 can be an Interrogating Session Border Controller (ISBC) in an IP Multimedia Subsystem (IMS) metropolitan area network, the radio access network 104 can be a base station gNB, and the user plane function of the radio core network can be a 5G to Business User Plane Function (5G ToB UPF).

[0035] In one implementation, the customer premises equipment connects to the wired network via a fiber optic cable and to the wireless network via a fifth-generation subscriber identity module (5G SIM). During use, both the first and second path links are active to achieve hot backup.

[0036] In one implementation, connectivity detection and path switching are performed on the customer premises equipment side. Since the second path already has wireless access capabilities and forwarding capabilities with the network side on the equipment side, there is no need to rebuild the session or reconfigure the service on the voice platform side when performing path switching. The switching process is controlled by the customer premises equipment, thus improving switching efficiency. Under normal circumstances, the switchback can be achieved within a set time such as 50ms.

[0037] In one implementation, the construction of the first path includes: enabling the customer premises equipment to access the bearer network via the access layer equipment, and enabling the bearer network to interface with the voice platform.

[0038] For example, see Figure 3 The customer premises equipment connects to the wired network through its first access interface. The first access interface is a wired interface, and the customer premises equipment connects to the bearer network through the access layer equipment, thereby enabling voice service data to be introduced from the customer side into the bearer network for forwarding and processing.

[0039] In the interface between the bearer network and the voice platform, voice service data is transmitted along the pre-configured service tunnels or forwarding paths in the bearer network. The network-facing provider edge (NPE) of the bearer network interfaces with the access switch (such as the switching equipment in the IMS network, abbreviated as IMS-SW) on the voice platform side, so that voice service data can be forwarded across domains from the bearer network to the voice platform.

[0040] Through the above access and connection process, voice service data can be transmitted end-to-end to the voice platform via the bearer network.

[0041] In one implementation, the construction of the second path includes: enabling customer premises equipment to access the user plane function of the wireless core network via the wireless access network; enabling the user plane function of the wireless core network to interface with the bearer network; and enabling the bearer network to interface with the voice platform.

[0042] For example, see Figure 3 The customer premises equipment accesses the wireless network through its second access interface. In one implementation, the second access interface is a wireless interface. The customer premises equipment accesses the user plane function of the wireless core network through the wireless access network, enabling voice service data to be forwarded from the customer side to the wireless core network via the wireless network. In the wireless core network, the user plane function forwards the voice service data and introduces it into the bearer network for further transmission. Through the above-mentioned wireless access, core network user plane forwarding, and bearer network connection process, voice service data can be transmitted to the voice platform sequentially via the wireless access network, the user plane function of the wireless core network, and the bearer network, thus completing the end-to-end construction of the second path.

[0043] In one implementation, during transmission along the second path, voice service data is carried out in at least one of the following ways: Voice service data is carried between customer site equipment and the voice platform using a tunneling transmission method; Voice service data is encapsulated and carried between the customer's premises equipment and the gateway of the bearer network based on a general routing encapsulation protocol; Voice service data is transmitted between the user plane functions of the radio access network and the radio core network based on the user plane tunnel, and between the user plane functions of the radio core network and the gateway of the bearer network based on the general routing encapsulation protocol.

[0044] The above configuration enables voice service data to be transmitted in different network segments along the second path using bearer or encapsulation methods adapted to those network segments, thereby achieving end-to-end transmission of voice service data to the voice platform via the wireless access path. In one example, during transmission along the second path, voice service data is carried using all of the above methods.

[0045] For example, the wireless link in the second path can achieve end-to-end transmission of voice service data through a combination of various tunnels. In this example, tunnels at different levels operate on different network segments to encapsulate and forward voice service data. However, the embodiments of this application do not limit the specific number of tunnel layers, tunnel types, or their nesting relationships.

[0046] For example, a service layer tunnel based on the Secure Real-time Transport Protocol (SR-TP) can be established between the customer's on-site equipment and the voice platform to provide end-to-end protection for voice service data; A logical tunnel based on the Generic Routing Encapsulation (GRE) protocol can be established between the customer’s premises equipment and the gateway of the bearer network to carry the service layer tunnel. Between the user plane functions of the radio access network and the radio core network, a user plane tunnel (GPRSTunneling Protocol, GTP tunnel) can be established to carry voice service data from the radio access side. A forwarding tunnel based on a general routing encapsulation protocol can be established between the user plane function of the wireless core network and the gateway of the bearer network to introduce voice service data into the bearer network.

[0047] In one implementation, the second path can be achieved through a multi-layered nested tunnel connection. The first layer is the SR-TP tunnel between the CPE and the ISBC; the second layer is the CPE GRE tunnel between the CPE and the gateway; and the third layer is the GTP tunnel between the base station and the UPF, and the UPF GRE tunnel between the UPF and the gateway.

[0048] In one implementation, see Figure 4 The connectivity of the first path is checked, including: S401, send test messages to the first path according to a preset cycle.

[0049] In this embodiment, voice service data is carried on the first path, while the second path is in standby mode. The customer premises equipment detects the end-to-end connectivity of the first path by sending test messages to the first path.

[0050] For example, test messages can be generated based on various link detection mechanisms, such as Label Switched Path Ping (LSP Ping) and Pseudowire Virtual Circuit Connectivity Verification Ping (PW VCCV Ping) to diagnose the connectivity of wired links. Customer premises equipment can send test messages to the first path at preset intervals and determine the connectivity status of the first path based on whether a corresponding response message is received.

[0051] S402, if the number of times no response to the test message is detected consecutively reaches a preset threshold, the connectivity of the first path is determined to be abnormal.

[0052] In this step, if no response to the test message is received within several consecutive detection cycles, and the number of times the response is not received reaches a preset threshold, the customer's on-site equipment determines that the connectivity of the first path is abnormal.

[0053] For example, if no response to the test message is detected consecutively multiple times, it can be determined that the first path has lost connectivity, i.e., the first path has been interrupted. The preset period and preset threshold can be configured according to business needs. For example, the preset period can be set to a millisecond-level period, such as 3.3ms or 10ms. The "multiple times" in "when no response to the test message is detected consecutively multiple times" can be set according to requirements, such as 3 times, 5 times, etc.

[0054] In one implementation, see Figure 5 After controlling the switching of voice service data to transmission via the second access interface, the method further includes: S501 continuously detects the connectivity of the first path.

[0055] In this embodiment, while voice service data is transmitted via the second path, the customer premises equipment continues to continuously monitor the connectivity of the first path. This continuous monitoring is used to determine whether the first path has recovered from an abnormal state to a usable state, thereby providing a basis for subsequent service switchback decisions. The continuous monitoring method can be the same as or similar to the aforementioned connectivity monitoring method; for example, periodic monitoring of the first path based on test packets. This embodiment does not limit this approach.

[0056] S502, when the first path is detected to be reconnected, control the voice service data to switch back to transmission via the first access interface.

[0057] When the detection result shows that the first path has been restored to connectivity, the customer premises equipment controls the voice service data to switch back from the second path to the first path for transmission, that is, the voice service data is resent by the first access interface.

[0058] For example, in one specific implementation, the customer premises equipment can complete the switchback operation based on the path switching mechanism, thereby enabling voice service data to be transmitted again via the wired bearer path. For example, the service can be switched back to the wired link through switching methods such as Multi-Protocol Label Switching Operations, Administration, and Maintenance (MPLS OAM) and Multi-Protocol Label Switching Transport Profile Operations, Administration, and Maintenance (MPLS-TPOAM).

[0059] This application provides a voice service control method. By deploying customer premises equipment with wired and wireless dual access capabilities on the customer side, the voice service can simultaneously access the voice platform via both wired and wireless networks. This allows the voice service data to continue to be transmitted via the wireless network when the wired bearer path is abnormal, thereby improving the reliability of the voice service.

[0060] In this embodiment, the customer premises equipment is an access device equipped with both wired and wireless access interfaces. The customer premises equipment connects to the bearer network via the wired access interface and transmits voice service data to the voice platform via the bearer network. Simultaneously, the customer premises equipment connects to the wireless access network via the wireless access interface and transmits voice service data to the voice platform sequentially via the user plane function of the wireless core network and the bearer network.

[0061] On the network side, the user plane function of the wireless core network establishes a connection with the bearer network, and the bearer network further establishes a connection with the network-side equipment where the voice platform is located, thereby realizing end-to-end transmission of voice service data on the wireless bearer path.

[0062] The above configuration enables voice services to reach the voice platform from the customer side via both wired and wireless bearer paths.

[0063] The technical solution of this application embodiment involves the customer-side CPE connecting to the ISBC of the voice platform via both wired and wireless connections, allowing voice services to continue transmission via the second path after path switching. This includes: the customer-side using SPN CPE 01 to achieve dual wired and wireless access; and the core side simultaneously connecting the 5G core network, SPN metropolitan area network, and IMS metropolitan area network to complete the docking of the 5G ToB UPF with the NPE and the NPE with the IMS-SW.
