Description

Technical Field

[0001] This application belongs to the field of communication transmission and bearer, and particularly relates to a 4G network migration bearer method, apparatus, equipment and storage medium. Background Technology

[0002] 4G services are carried by the traditional PTN (Packet Transport Network), while 5G services are carried by the SPN (Slicing Packet Network). Furthermore, the 4G-related PTN and 5G-related SPN are independent networks. Currently, 4G and 5G services are deployed respectively in the PTN network radio service VPN (for 4G) and the SPN network radio service VPN (for 5G).

[0003] However, in this situation, when 4G users and 5G users interact with each other, there are problems such as long service paths, long time delays, and low communication quality. Summary of the Invention

[0004] This application provides a method, apparatus, device, and storage medium for migrating bearers in a 4G network, which can improve interaction efficiency.

[0005] In a first aspect, embodiments of this application provide a 4G network migration bearer method, which includes: adding an IP address and VLAN data to a 4G BBU, wherein the added IP address and VLAN data are used to cut the 4G BBU from a PTN network to an SPN network; adding a physical port, IP address, and VLAN data to the SPN network; disconnecting the physical fiber connection between the PTN network and the 4G BBU; and establishing a physical fiber connection between the added physical port on the SPN network and the physical port of the 4G BBU, thereby enabling communication between 4G and 5G networks based on the added IP address and VLAN data. This shortens the service path and reduces time latency during the communication between 4G and 5G networks, thereby improving interaction efficiency.

[0006] In one feasible implementation, IP addresses and VLAN data are added to the 4G BBU based on the principle of using different IP addresses and different VLAN data. This ensures a clear network structure, avoids network conflicts, and is easy to maintain while maintaining security and reliability.

[0007] In one feasible implementation, the physical port in the 4G BBU that connects to the SPN network reuses the original GE port that interfaced with the PTN network. This eliminates the need to purchase new network equipment, reducing costs.

[0008] In one feasible implementation, two sets of data are stored concurrently on the GE port of the 4G BBU device. One set of data is used for cutting off 4G service access to the PTN network before the cut-off, and the other set of data is used for cutting off 4G service access to the SPN network after the cut-off.

[0009] In one feasible implementation, the newly added physical port on the SPN network is located at the same site as the PTN network and the 4GBBU. This eliminates the need for external connections, requiring only internal connections, thus improving convenience, minimizing service interruption time, reducing latency, and lowering network risk.

[0010] In one feasible implementation, the IP addresses added on the SPN network and the IP addresses added by the 4G BBU are on the same available service addresses within the same 30-bit mask. Since the other service address is determined as soon as one service address is determined, operational complexity is reduced and time is saved.

[0011] In one feasible implementation, the newly added VLAN data on the 4G BBU and SPN are consistent. This enables real-time link establishment, rapid switching, and rapid recovery, reducing latency. In one feasible implementation, the cutover 4G and 5G services reside within the same VPN. Having both 4G and 5G services within the same VPN significantly improves interaction efficiency.

[0012] In one feasible implementation, the newly added IP address range of the 4G BBU is configured and added to the radio service VPN of the SPN network via the SPN network management OMC, so that 4G and 5G services are in the same VPN after the cutover. Adding IP addresses facilitates the integration of 4G and 5G services into the same VPN after the cutover.

[0013] In one feasible implementation, after the PTN network management OMC confirms that the service optical port of the PTN device that has migrated all 4G services is in a state of no light reception, the corresponding PTN device is decommissioned.

[0014] Secondly, embodiments of this application provide a 4G network migration bearer device, characterized in that the device includes: a first addition module, which adds IP addresses and VLAN data to a 4G BBU, the added IP addresses and VLAN data being used to cut the 4G BBU from a PTN network to an SPN network; a second addition module, which adds physical ports, IP addresses, and VLAN data to the SPN network; a disconnection module, which disconnects the physical fiber connection between the PTN network and the 4G BBU; and a connection module, which connects the added physical ports on the SPN network to the physical ports of the 4G BBU using physical fiber optic connections, and realizes communication between 4G and 5G using the SPN network based on the added IP addresses and VLAN data.

[0015] Thirdly, embodiments of this application provide a 4G network migration bearer device, the device including: a processor and a memory storing computer program instructions; the processor reads and executes the computer program instructions to implement the 4G network migration bearer method of the first aspect described above.

[0016] Fourthly, embodiments of this application provide a computer storage medium storing computer program instructions, which, when executed by a processor, implement the 4G network migration bearer method described in the first aspect above.

[0017] Fifthly, embodiments of this application provide a computer program product, including a computer program that, when executed, implements the 4G network migration bearer method described in the first aspect above.

[0018] The 4G network migration bearer method, apparatus, device, and storage medium of this application embodiment add an IP address and VLAN data to the SPN on the 4G BBU to be migrated, and then pre-configure an IP address with the same subnet mask and the same VLAN data on the SPN as the newly added IP address on the 4G BBU. Subsequently, the fiber optic connection between the PTN and the 4G BBU is disconnected, and the physical ports of the SPN and the 4G BBU are connected. This can shorten the service path of 4G services and 5G services, reduce time latency, and thus improve interaction efficiency. Attached Figure Description

Detailed Implementation

[0021] Before describing the technical solution of this application, the technical solutions of the prior art will be described first.

[0022] Figure 1 This is a schematic diagram illustrating the existing 4G / 5G services and PTN / SPN bearer systems and service flows.

[0023] In existing technologies, the interaction between 4G and 5G services is achieved through the exchange of the User Network Interface (UNI) between the PTN and SPN via core landing equipment (e.g., Figure 1 As shown in ④ and ⑤, it can be seen that in the existing technology, the interaction between 4G services and 5G services requires passing through devices at each layer of the PTN network and SPN network (such as...). Figure 1 (Link shown in ①).

[0024] Therefore, the existing technical solutions have the following drawbacks: First, 4G and 5G services are carried by PTN and SPN networks respectively, resulting in insufficient service integration, excessively long interaction latency, and a certain degree of impact on network quality; Second, the user data interaction path between 4G and 5G services is too long, requiring a lengthy path such as 4G user → 4G base station → access aggregation backbone PTN network → core PTN network → core SPN network → access aggregation backbone SPN network → 5G base station → 5G user (e.g., Figure 1 (This requires traversing the entire PTN and SPN network paths).

[0025] In this application, in order to better meet the requirements of 4G and 5G services for low latency, high integration, and high quality, a 4G network migration bearer method, apparatus, device, and storage medium are proposed.

[0026] The features and exemplary embodiments of various aspects of this application will be described in detail below. To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain this application and not to limit it. For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples.

[0027] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes said element.

[0028] The 4G network migration bearer method provided in the embodiments of this application will be introduced first below.

[0029] Figure 2 This diagram illustrates a 4G service migration process provided in one embodiment of this application.

[0030] Figure 3This diagram illustrates a flowchart of a 4G network bearer migration method according to an embodiment of this application. Figure 3 As shown, the method may include steps S10 to S40.

[0031] In step S10, add (or extend) IP addresses and VLAN data on the 4G BBU.

[0032] Here, the newly added (or expanded) IP addresses and VLAN data are used to cut over the 4G BBU (Building Baseband Unit) from the PTN network to the SPN network, that is, to migrate it from the PTN network to the SPN network.

[0033] In step S10, IP addresses and VLAN data can be added (or extended) based on the principle of different IP addresses and different VLAN data. This ensures a clear network structure, avoids network conflicts, and is easy to maintain and secure.

[0034] Figure 4 This is a flowchart illustrating an example of the process of adding new IP addresses and VLAN data according to an embodiment of this application. Figure 4 As shown, the process of adding (or expanding) IP addresses and VLAN data may include steps S11 to S13.

[0035] In step S11, plan the addition (or expansion) of IP addresses and VLAN data on the 4G BBU.

[0036] Specifically, on 4G BBU devices, planning can be carried out based on the principle of expanding the deployment of different IP addresses and different VLAN data (without conflict).

[0037] For example, if the existing IP address for the PTN network on the 4G BBU is 100.*.*.2 / 26 and the VLAN data is 333, based on the principle of different IP addresses and different VLAN data, and the SPN network 4G access IP and VLAN deployment specifications, the newly added IP address for the SPN network can be determined to be 10*.*.1 / 30 and the VLAN data to be 666. This ensures that the newly added (extended) IP address and VLAN data on the 4G BBU do not conflict with the existing IP address and VLAN data.

[0038] In step S12, the physical port is determined on the 4G BBU.

[0039] The physical ports of the 4G BBU can still reuse the original GE ports that were used to connect to the PTN network.

[0040] For example, when the original port is slot 1, port 1 on a 4G BBU device, the newly added IP address and VLAN data are configured on the original physical port (slot 1, port 1).

[0041] By reusing the existing GE ports that connect to the PTN network, there is no need to purchase new network equipment, which can reduce costs.

[0042] In step S13, new (extended) IP addresses and VLAN data are deployed on the 4G BBU.

[0043] Based on the wireless network management OMC system that manages the 4G BBU, the IP address and VLAN data for the SPN device added in step S11 can be sent to the GE physical port of the 4G BBU device determined in step S12.

[0044] For example, the newly added IP address for the SPN device, 10*.*.1 / 30, and VLAN data 666 are sent to the GE physical port (1 slot, 1 port) of the 4GBBU device.

[0045] The wireless network management OMC system that manages the 4G BBU can also check the underlying layer to confirm that IP addresses and VLAN data are effective on the 4G BBU device.

[0046] Through the processing in steps S11 to S13 above, two types of data coexist on the 4G BBU. One set of data consists of newly added (extended) IP address and VLAN data on the 4G BBU (e.g., IP address 10.*.*.1 / 30, VLAN data 666), which is used for 4G service access to the SPN network after the cutover. The other set of data consists of existing IP address and VLAN data on the 4G BBU (e.g., IP address 100.*.*.2 / 26, VLAN data 333), which is used for 4G service access to the PTN network before the cutover (current situation). These two sets of data coexist on the GE physical port of the 4G BBU device (e.g., slot 1, port 1 of the 4G BBU device).

[0047] return Figure 3 In step S20, add physical ports, IP addresses, and VLAN data to the SPN network.

[0048] As an example, the newly added physical ports on the SPN network are located at the same site as the PTN network and the 4G BBU. For example, Figure 2In steps ①, ②, and ⑤, all ports are located at the same site, i.e., within the same physical equipment room. By placing the newly added physical ports on the SPN network at the same site as the PTN network and the 4G BBU, only internal connections are required, improving convenience, minimizing service interruption time, reducing latency, and lowering network risk. Conversely, if the newly added physical ports on the SPN network are placed at different sites than the PTN network and the 4G BBU, external fiber optic connections are required, resulting in longer service interruption times and higher network risk.

[0049] Figure 5 This is a flowchart illustrating an example of the process of adding physical ports, IP addresses, and VLAN data on an SPN network according to an embodiment of this application.

[0050] like Figure 5 As shown, the process of adding physical ports, IP addresses, and VLAN data on an SPN network may include steps S21 to S23.

[0051] In step S21, the planning of new IP addresses and VLAN data is carried out on the SPN network.

[0052] This allows newly added IP addresses on the SPN network and newly added IP addresses on the 4G BBU to be within the same 30-bit mask of available service addresses. Since both service addresses are within the same 30-bit mask, it can be assumed that once one service address is determined, the other service address is also determined accordingly, thus reducing operational complexity and saving time.

[0053] In addition, the VLAN data added on the SPN network is consistent with the VLAN data added on the 4G BBU.

[0054] As an example, given that the newly added IP address on the 4G BBU facing the SPN network is 10*.*.1 / 30 and the VLAN data is 666, since within the same 30-bit mask, the network address of 10*.*.1 / 30 is 10.*.*.0, the broadcast address is 10.*.*.3, and the service address (service available address) is 10*.*.1 (10*.*.1 / 30) and 10*.*.2 (10*.*.2 / 30), the newly planned IP address on the SPN must be an available service address within the same 30-bit mask as the newly added (extended) IP address on the 4G BBU, and the VLAN data must be consistent with the newly added VLAN data on the 4G BBU, the newly confirmed IP address on the SPN is 10*.*.2 / 30 and the VLAN data is 666.

[0055] In step S22, the newly added physical ports on the SPN network are identified.

[0056] Since the 4G BBU uses a GE rate physical port, the physical port rate attribute selected on the SPN must also match it. Therefore, the corresponding GE port is selected on the SPN.

[0057] For example, if the GE port used on the 4G BBU is 1 slot and 1 port, the physical port added on the SPN is also 1 slot and 1 port.

[0058] In step S23, the newly added IP addresses and VLAN data are deployed on the SPN network.

[0059] Based on the network management OMC system that manages the SPN network, the IP address and VLAN data of the SPN network added in step S21 can be sent to the GE physical port of the SPN network determined in step S22.

[0060] For example, the newly added IP address 10*.*.2 / 30 and VLAN data 666 for the 4G BBU device are sent to the GE physical port (1 slot, 1 port) of the 4G BBU device. The OMC system, which manages the SPN network, can also check the underlying layer to confirm that IP addresses and VLAN data are effective on the SPN devices.

[0061] Through steps S21 to S23, a set of data exists on the SPN device. This set of data is used for service access to the 4G BBU device after the cutover. This set of data is effective on the GE physical port of the SPN device. For example, the IP address of this set of data can be 10*.*.2 / 30, the VLAN data can be 666, and the GE physical port of the SPN device can be slot 1, port 1.

[0062] return Figure 3 In step S30, the physical fiber optic connection between the PTN network and the 4G BBU is disconnected. In other words, step S30 performs the "cut" in the "cutover" process.

[0063] Before the cutover, the PTN network and the 4G BBU's GE physical port (e.g., the 1 slot 1 port mentioned above) are interconnected via a two-core fiber optic cable (one for receiving and one for transmitting). Therefore, it is necessary to disconnect the physical connection between the PTN network and the 4G BBU via the two-core fiber optic cable connected through the GE physical port. When the PTN device and the 4G BBU device report a port no-light alarm to the PTN network management OMC, it can be confirmed that the physical fiber optic cable has been disconnected.

[0064] In step S40, the newly added physical port on the SPN network is physically connected to the physical port of the 4G BBU via fiber optic cable, and communication between 4G and 5G is achieved using the SPN network based on the newly added IP address and VLAN data. In other words, step S30 realizes the "connection" in the "cutover".

[0065] Since the SPN device has already determined its GE physical port (e.g., 1 slot, 1 port) in step S20, and the 4G BBU device has also determined its GE physical port (e.g., 1 slot, 1 port), and both are at GE speed, the GE physical ports of the SPN device and the GE physical ports of the 4G BBU device can be interconnected through two-core optical fibers, and the ports can be confirmed to be in the UP state in the transmission SPN network management OMC and the wireless 4G BBU network management OMC.

[0066] Through steps S10 to S40 above, the 4G BBU can be cut over from the PTN network to the SPN network. Since the interaction between 4G and 5G is based on the newly added (extended) 4G IP addresses and VLAN data on the 4G BBU and SPN networks, when 4G and 5G interact, it is not necessary to traverse the entire network path of PTN and SPN as in the existing technology. This can shorten the service path, reduce time latency, and thus improve the interaction efficiency.

[0067] Furthermore, by ensuring that the VLAN data of the newly added 4G BBU and the SPN network are consistent and that the service addresses are two available service addresses within the same 30-bit mask, the 4G BBU's services can be plug-and-play on the SPN network based on the attributes of the VLAN data and IP addresses. In other words, after the physical ports of the two devices are interconnected by fiber optic cable, 4G services can immediately be implemented on the SPN network, enabling real-time link establishment, rapid switching, and rapid recovery, thus reducing latency.

[0068] Figure 6 This is a schematic diagram illustrating the business flow after migration according to an embodiment of this application.

[0069] like Figure 6 As shown, steps S10 to S40 above complete the 4G BBU's access to the PTN network. Figure 6 The access point shown in ⑥ is migrated to access the SPN network. Figure 6 (Access point shown in ③).

[0070] After the cutover (migration), both 4G BBU and 5G BBU services are carried by the SPN network. Specifically, the 4G BBU achieves interconnection and access with the SPN network (e.g., Figure 6 As shown in ③, it has broken away from the PTN network (such as...). Figure 6(As shown in ⑥, there is no longer a 4G BBU access point), while the existing 5G BBU has been interconnected and accessed by the SPN network (such as...). Figure 3 As shown in ②), it is possible to ultimately achieve simultaneous access of the migrated 4G BBU service and the original 5G BBU service on the SPN network, that is, both 4G and 5G services belong to the "wireless service VPN" on the SPN network.

[0071] Since the 4G BBU and 5G BBU services are deployed uniformly within the "Radio Service VPN" of the SPN network after the cutover, meaning 4G and 5G coexist, the interaction between 4G and 5G services only needs to occur within the "Radio Service VPN" of the SPN network (e.g., Figure 6 (As shown in ④). Specifically, to achieve efficient interoperability between 4G and 5G services carried on the SPN network, the planning principles can be followed to ensure that 4G and 5G services are in the same VPN. The address range used by the 4G BBU (e.g., 10.*.*.1 / 30) is added to the "Wireless Service VPN" of the SPN network on the SPN network management OMC. The activation can be confirmed by querying the corresponding VPN configuration of the SPN network.

[0072] It's important to note that VPN typically refers to site-to-site network technology. The advantages of deploying services within the same VPN are as follows: First, optimal path: communication within the VPN means data packets are transmitted within the VPN tunnel or the operator's MPLS backbone. This is a well-planned and optimized path, generally meaning fewer network hops and lower latency. Second, less processing overhead: communication within the VPN involves label switching in the core network, which is faster than traditional IP routing lookups and eliminates encryption / decryption overhead. In most well-designed and planned networks, addresses within the same VPN have significantly higher interaction efficiency due to lower latency and more guaranteed bandwidth, resulting in much higher efficiency than addresses interacting across different VPNs. This is because data follows a more direct, optimized path with fewer processing steps. Furthermore, since service operations only occur within the SPN network's wireless service VPN, service latency is effectively reduced, improving communication quality. In other words, when 4G and 5G services are within the same VPN, interaction efficiency and communication quality can be significantly improved.

[0073] Since the 4G BBU service and 5G BBU service interact within the same VPN ("Wireless Service VPN") on the SPN network after the cutover, the transmission path is within the SPN network. Because communication occurs within the SPN network, the transmission path can be the shortest point-to-point direct path within the SPN network (e.g., ...). Figure 6 (Link shown in ①).

[0074] Devices and data within the same VPN, regardless of their physical distance, are logically configured to belong to the same trusted, private local area network (LAN). This makes their interaction methods exactly the same as in a physical office intranet, thereby effectively reducing business latency and improving network quality.

[0075] In addition, after the cutover, the original PTN network equipment can be gradually decommissioned (e.g., Figure 6 (See device shown in section ⑥). Specifically, once the service optical port of a PTN device that has migrated all 4G services is confirmed to be in a no-light state by the transmission PTN network management OMC, the corresponding PTN device can be decommissioned.

[0076] The conditions for decommissioning PTN equipment are as follows: First, the 4G BBU has been migrated using the migration method described above; second, through the batch execution of the migration method described above, the migration of all services of the PTN equipment network can be completed. If both of these conditions are met, the PTN equipment can be considered to meet the conditions for decommissioning.

[0077] Assuming that the PTN equipment has completed the service clearance through the above migration method, the offline decommissioning operation can be performed in the following manner: First, clear all fiber optic connections between the PTN equipment and other equipment; second, power down the PTN equipment; and finally, remove the PTN equipment from the field equipment room.

[0078] Since the original PTN network equipment itself is also an over-serviced device with a high failure rate, decommissioning the original PTN network equipment can reduce the impact of the high failure rate of old equipment on services, reduce power consumption, free up data center space, and save on electricity, site rental and other costs.

[0079] The deployment and maintenance of SPN equipment can also promote the upgrading and replacement of domestically produced chips, improve maintenance convenience, and contribute to the secure iteration of independent technologies.

[0082] Here, the newly added (or expanded) IP addresses and VLAN data are used to cut over the 4G BBU from the PTN network to the SPN network, that is, to migrate it from the PTN network to the SPN network.
