Technical Field

[0001] This application relates to the field of communication technology, and in particular to a method, apparatus and storage medium for expanding a link. Background Technology

[0002] The policy control function (PCF) network element, binding support function (BSF) network element, and diameter routing agent (DRA) network element have opened Internet Protocol (IP) links, which enables the provision of dedicated voice loadout session binding function for users when using voice services, thereby improving the user's call experience.

[0003] With the continuous growth of 5G users, the already limited capacity of PCF network elements urgently needs expansion. In traditional expansion processes, PCF, BSF, and DRA network elements all require the creation of new link data. Each network element requires different engineers to perform data operations, and the amount of data to be created each time is enormous. Furthermore, the IP addresses to be connected also require manual verification, resulting in low workload and accuracy. Therefore, improving the efficiency and accuracy of link expansion is a pressing issue that needs to be addressed. Summary of the Invention

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0024] In the description of this application, unless otherwise stated, " / " means "or," for example, A / B can mean A or B. The "and / or" in this document is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, and B alone. Furthermore, "at least one" means one or more, and "multiple" means two or more. The words "first," "second," etc., do not limit the quantity or order of execution, and "first," "second," etc., do not necessarily imply differences. It should be noted that in this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or explanations.

[0025] Any embodiment or design described as "exemplary" or "for example" in this application should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner. In embodiments of this application, "instruction" can include direct instruction and indirect instruction. For example, taking the first control information hereinafter as an example, the first control information can directly carry information A itself or its index to achieve the purpose of directly instructing information A. Alternatively, the first control information can also carry information B that is associated with information A, thereby achieving the purpose of indirectly instructing information A while instructing information B.

[0026] As described in the background section, in traditional link expansion processes, the link data for PCF, DRA, and BSF network elements all require different engineers to create the data, resulting in significant manpower consumption. The specific link expansion process primarily involves a diameter load balancer (DLB) module. This module is used for distributing and processing expansion services. This module resides in virtual machines, with two DLB modules within each virtual machine. For example, expanding the capacity of a PCF network element from 3 million to 5 million requires expanding two virtual machines, each containing four DLB modules. The expansion requires two links. Each operator has approximately 26 PCF network elements, meaning that completing this expansion requires configuring 52 link data entries for the PCF network elements. In addition, the peer devices DRA and BSF network elements of the PCF network elements require a total of 156 link data entries to be configured. Furthermore, after different engineers have configured the link data, a significant amount of manpower is needed to verify and allocate the link data, making the process very complex. As a result, the efficiency of the link expansion is very low, and the accuracy of the link expansion cannot be guaranteed due to manual verification.

[0027] Based on this, this application provides a link expansion method that can improve the efficiency and accuracy of link expansion. The approach is as follows: when link expansion is required, the configuration data of the link to be configured is directly obtained from preset configuration data, a configuration script is generated, and sent to the PCF network element and its peer device, enabling the PCF network element and its peer device to configure the link to be configured.

[0028] For example, Figure 1 This diagram illustrates the structure of a capacity expansion system according to an embodiment of this application. The capacity expansion system may include a server and PCF network elements. The server may be connected to one or more PCF network elements. It should be noted that... Figure 1 The diagram shown is merely a structural schematic of the expansion system that can be applied to the embodiments of this application, in order to help those skilled in the art understand the technical content of this disclosure, but it does not mean that the embodiments of this application cannot be used in other devices, systems, environments or scenarios.

[0029] The PCF network element is a policy control function network element, belonging to the standard 5GC network element, used to provide access mobility policy control functions and session management policy control functions.

[0030] The link expansion device is used to store and distribute preset configuration data. The link expansion device can be a standalone physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server providing basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, content delivery network (CDN), and big data and artificial intelligence platforms. The following description uses the link expansion device as a server to exemplify the link expansion method provided in this embodiment of the invention.

[0031] It should be noted that, Figure 1 This is just an example structural diagram. Figure 1 The number of structures included, and the names of each structure, are unlimited, except for... Figure 1 In addition to the structure shown, this system architecture may also include other structures.

[0032] The application scenarios of the embodiments in this application are not limited. The system architecture and business scenarios described in the embodiments of this application are for the purpose of more clearly illustrating the technical solutions of the embodiments of this application, and do not constitute a limitation on the technical solutions provided by the embodiments of this application. As those skilled in the art will know, with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided by the embodiments of this application are also applicable to similar technical problems.

[0033] like Figure 2 The embodiment of this application provides a link expansion method, which includes the following steps:

[0034] S201. In response to the detection that the policy control function PCF network element needs to expand the link capacity, the configuration data of the link to be configured is obtained from the preset configuration data.

[0035] In some embodiments, when a PCF network element needs to expand its link capacity, the server used to perform the link expansion work of the PCF network element receives expansion request information sent by the maintenance system; or, the server used to perform the link expansion work of the PCF network element receives expansion request information sent by the PCF network element.

[0036] The expansion request information is used to instruct the aforementioned servers to perform link expansion work for PCF network elements.

[0037] It is understandable that the link expansion work of PCF network elements can be carried out periodically, with the aforementioned maintenance system periodically sending expansion request information to the aforementioned server; or, when the capacity used by the PCF network element is about to reach its capacity limit, the PCF network element actively sends expansion request information to the aforementioned server.

[0038] For example, the expected cycle for PCF network element link expansion is 72 hours. That is, every 72 hours, the maintenance system sends an expansion request to the server to instruct the server to perform link expansion for the PCF network element. Alternatively, when the PCF network element's capacity is already 90% utilized, the PCF network element proactively sends an expansion request to the server. In this case, even if the next expansion cycle has not yet arrived, the server will still perform link expansion for the PCF network element.

[0039] The preset configuration data includes configuration data for multiple links. The configuration data for each link includes the link information of the PCF network element, the link information of the peer device, and the status of the link. The status of the link includes enabled or disabled status.

[0040] In some embodiments, when the server receives a capacity expansion request from the maintenance system or PCF network element, the server searches for the configuration data of the disabled links in the preset configuration data; and uses the configuration data of the disabled links as the link data of the link to be configured.

[0041] For example, if the configuration data of an enabled link is abnormal, when the server detects the configuration data, it marks the configuration data and sends it to the maintenance system for error handling.

[0042] The link information for PCF network elements includes: device name, interface type, working mode, port number, and IP address; the link information for peer devices includes: device name, DRA working mode, port number, and IP address.

[0043] In some embodiments, the ratio of the link information of the PCF network element to the link information of the peer device is 1:2.

[0044] For example, the peer device of a PCF network element can be a DRA network element or a BSF network element. As shown in Tables 1 and 2, Tables 1 and 2 show the preset configuration data with the peer device of the PCF network element being a DRA network element. This preset configuration data includes the configuration data of 10 links. Among them, the link information of the PCF network element is 10, the link information of the DRA1 network element is 5, and the link information of the DRA2 network element is 5.

[0045] Table 1

[0046]

[0047] Table 2

[0048]

[0049] The working mode in the link information of the PCF network element can be either server mode or client mode, while the DRA working mode of the peer device of the PCF network element can only be client mode.

[0050] It should be noted that during the operation of a PCF network element, it establishes an IP link with the peer device to jointly provide services to users. Therefore, when a PCF network element needs to expand its link capacity, its peer device also needs to expand its link capacity.

[0051] In some embodiments, the link configuration data also includes link usage information. The server searches for configuration data of unused links from preset configuration data; the configuration data of the unused links is used as the link data for the link to be configured.

[0052] The configuration data of the used link is the configuration data of the IP address used in the link configuration data.

[0053] It is understandable that when an IP address is shown to be in use, it proves that the configuration data has been used by other network elements or devices. When performing link expansion work, the configuration data of the IP address that has been used should be deleted or marked. In subsequent link expansion work, the configuration data of the IP address that has not been used should be used to complete the expansion work.

[0054] In some embodiments, the server obtains the configuration data of the links to be configured based on the number of links to be configured.

[0055] The number of links to be configured can be determined based on the recent capacity usage of PCF network elements; or it can be set manually.

[0056] For example, when the number of 5G users is growing rapidly and the PCF network element needs to frequently expand its links, the number of links to be configured can be appropriately increased to avoid frequent expansions and reduced efficiency of the PCF network element. Alternatively, when the number of 5G users is growing slowly, the number of links to be configured can be appropriately reduced to avoid wasting resources due to a large number of link expansions.

[0057] As another example, in this link expansion process, there are 2 links to be configured. The server obtains the configuration data of 2 disabled links from the preset configuration data so as to complete the subsequent link expansion work.

[0058] S202. Generate a configuration script based on the configuration data of the link to be configured.

[0059] The configuration script includes the device name, link identifier, and port number. The configuration script is used to instruct PCF network elements and peer devices to perform link expansion.

[0060] For example, the server packages the configuration data of the link to be configured into a configuration script. When the PCF network element executes the configuration script, the PCF network element will obtain the configuration data of the corresponding link to be configured.

[0061] S203. Send the configuration script to the PCF network element and the peer device in the link to be configured that is opposite to the PCF network element.

[0062] In some embodiments, after the server sends the configuration script to the PCF network element and the peer device on the link to be configured, it logs into the PCF network element and the peer device using the file transfer protocol (FTP) and executes the configuration script so that the PCF network element and the peer device can configure the link to be configured.

[0063] For example, after the server sends the configuration script to the PCF network element and the peer device, the PCF network element and the peer device are logged in using FTP to execute the configuration script. After executing the configuration script, the PCF network element and the peer device obtain the configuration data of the link to be configured corresponding to the configuration script, and then the PCF network element and the peer device perform configuration work on the link to be configured according to the corresponding configuration data.

[0064] In this way, when a PCF network element and its peer device need to expand the link capacity, configuration data can be directly obtained from the preset configuration data. Then, a configuration script can be generated based on the configuration data and sent to the PCF network element and its peer device. This enables the PCF network element to configure the link to be configured, thus automating the link expansion and improving the accuracy and efficiency of the link expansion.

[0065] In some embodiments, based on Figure 2 In the embodiment shown, the method further includes: obtaining a first number of links configured by the PCF network element before running the script; obtaining a second number of links configured by the PCF network element after running the script; determining whether the difference between the second number and the first number is equal to the number of links to be configured; and determining that the link expansion is successful if the difference between the second number and the first number is equal to the number of links to be configured.

[0066] As one possible implementation, the server obtains the number of links of the PCF network element before and after running the script by executing link verification commands.

[0067] For example, the link verification command can be LST PEERL.

[0068] When the server executes the link verification command, the information obtained in the link data includes: number of links, link status, network element identifier, peer type, peer link identifier, distribution mode, transmission protocol type, dual-homed IP version, IP version, dual-homed IPv4 address, dual-homed IPv6 address, local IPv4 address, local IPv6 address, local port, dual-homed peer IPv4 address, dual-homed peer IPv6 address, peer IPv4 address, peer IPv6 address, and peer port.

[0069] For example, after receiving the link request information, the server executes a link verification command to obtain the first number of PCF network element links and marks the disabled links so that the maintenance system can process them. After the PCF network element runs the script and the link expansion is completed, the server executes the link verification command again to obtain the second number of PCF network element links and marks the disabled links. If the difference between the second number and the first number is equal to the number of links to be configured, the link expansion is considered successful.

[0070] Understandably, by executing the link verification command, the server can not only obtain the number of links before and after the PCF network element executes the script, but also obtain the enabling status of the links. It can not only determine whether the link expansion was successful based on the number of links, but also handle error reporting for disabled links based on their enabling status.

[0071] In other embodiments, if the difference between the second number and the first number is less than the number of links to be configured, the configuration data of the links to be configured that were not successfully configured is obtained; a new configuration script is generated based on the configuration data of the links to be configured that were not successfully configured; and the new configuration script is sent to the PCF network element and the peer device.

[0072] For example, in this link expansion process, the number of links to be configured is 6, and the difference between the second number and the first number is 4, proving that there are links that were not successfully configured in this link expansion process, and the number of links that were not successfully configured is 2. The PCF network element sends an alarm message to the server, indicating that there are two links that were not successfully configured in this link expansion process. After receiving the alarm message, the server re-obtains the configuration data of the unconfigured links to be configured from the preset configuration data, and then generates a new configuration script based on the configuration data, and sends it to the PCF network element and the peer device, so that the PCF network element and the peer device can continue to configure the two unconfigured links.

[0073] In this way, after the link expansion is completed, the success of the expansion is determined by comparing the number of links before and after the PCF network element runs the script, improving the accuracy and stability of the expansion. If the expansion fails, the configuration script is resent to the PCF network element and the peer device to re-expand the link, ensuring successful configuration of the link to be configured.

[0074] Figure 3 This application provides a complete flowchart of a link expansion method according to an embodiment, such as... Figure 3 As shown, the method includes the following steps:

[0075] S301. Obtain the first number of links configured by the PCF network element before running the script.

[0076] In response to the detection that the PCF network element needs to expand its links, the server begins to obtain the first number of links that the PCF network element has configured before running the script.

[0077] S302. Obtain the configuration data of the link to be configured from the preset configuration data.

[0078] S303. Send the configuration script to the PCF network element and the peer device in the link to be configured that is opposite to the PCF network element.

[0079] The configuration script is used to instruct the PCF network element and the peer device on the link to be configured to configure the link.

[0080] S304. Obtain the second number of links configured by the PCF network element after running the script.

[0081] S305. Determine whether the difference between the second number and the first number is equal to the number of links to be configured.

[0082] If the difference between the second number and the first number is equal to the number of links to be configured, then execute S306.

[0083] If the difference between the second number and the first number is greater than or less than the number of links to be configured, then execute S302 to obtain the configuration data of the links that were not successfully configured and continue to complete this expansion work.

[0084] S306. Confirmation: This link expansion was successful.
