Description

Technical Field

[0001] The present application relates to the field of mobile communication technology, and in particular to a patch repair method and device. Background Art

[0002] In wireless communication systems, network slicing cuts a physical network into multiple virtual end-to-end networks. Network slices can be used by operators to provide isolated and customizable network services for different vertical industries, different customers, and different businesses based on the Service Level Agreement (SLA) signed between operators and customers. A network slice is a logical network that provides specific network capabilities and features. The logical network slice is carried by a network slice instance. A network slice instance is a deployed network slice, including some network function instances and required resources, such as computing, storage, and network, to achieve the design, deployment, and operation of customized network slices.

[0003] The 5th Generation Mobile Communication Technology (5G) system is different from the traditional communication network. The composition of the traditional communication network elements is fixed and static. However, the 5G network slice is created on demand and is dynamic. The creation process is controlled by the Network Slice Management Function (NSMF) network element and is dynamically created according to the slice blueprint designed according to the SLA requirements of the network slice. The network slice also changes dynamically during operation and will be dynamically adjusted according to the performance monitoring of the network slice and the operation and maintenance strategy, such as adding virtualized network functions (VNF) or deleting VNF, automatically scaling, or dynamically adding and deleting interface function components and business processing function components in VNF.

[0004] However, due to the complexity of 5G network slicing and the dynamic nature of the network, when a network element or a functional component in a network element requires a hot patch, the hot patch operation of the 5G network slice becomes more difficult, and in some scenarios, it is even easy to fail. Specifically, in a virtualized scenario, since network elements are created dynamically, such as virtual Customer Premises Equipment (vCPE) devices or virtual top-box devices, both of which are dynamically created in the data center, the number is huge, possibly tens of thousands; if the time of dynamic creation is different, the version used may also be different; for example, the latest created network element may have adopted the new version and no longer requires a hot patch, and only the earlier created ones in operation may require a hot patch. Therefore, the hot patch operation of 5G network slicing becomes more difficult. Summary of the invention

[0038] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0039] It should be understood that the references to "one embodiment" or "an embodiment" throughout the specification mean that the specific features, structures, or characteristics associated with the embodiment are included in at least one embodiment of the present application. Therefore, the references to "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. In addition, these specific features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0040] In various embodiments of the present application, it should be understood that the size of the sequence number of each process described below does not mean the order of execution, and the order of execution of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiment of the present application. The terms "first", "second", etc. in the specification and claims are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally represents that the objects associated before and after are a kind of "or" relationship.

[0041] In the embodiments provided in the present application, it should be understood that "B corresponding to A" means that B is associated with A, and B can be determined according to A. However, it should also be understood that determining B according to A does not mean determining B only according to A, and B can also be determined according to A and / or other information.

[0042] In 5G networks, network slices include wireless subslices in the wireless domain, transmission subslices in the transmission domain, and core network subslices in the core network domain; wireless subslices such as centralized unit (CU) network elements, distributed unit (DU) network elements, and base stations (gNB) form wireless subslices; transmission subslices such as transmission subslices formed by transmission equipment in the transmission domain; transmission subslices such as core network domain access and mobility management functions (Access and Mobility Management Function), session management function (Session Management Function, SMF), user plane function (User Plane Function), network slice selection function (Network Slice Selection Function, NSSF), network element repository function (NF Repository Function, NRF), network capability exposure function (Network Exposure Function, NEF), short message service function (Short Message Service Function, SMSF) and other virtual network functions form core network subslices. Under the management of the slice management system, network subslices and internal virtual network functions together constitute end-to-end network slices to provide network communication services. Due to the complexity of 5G network slicing and the dynamic nature of the network, when a network element or a functional component in a network element needs to be hot-patched, the hot-patching operation of 5G network slicing becomes more difficult, and in some scenarios, the operation may even fail. Figure 1 As shown, an embodiment of the present application provides a patch repair method, which is applied to a slice management system, including:

[0043] Step 101, parse the patch description file, determine the target virtualized network function VNF, the target VNF ​​component VNFC of the target VNF, and obtain the VNFC patch of the target VNFC; wherein the target VNF ​​is the VNF of the target network slice corresponding to the patch description file.

[0044] Among them, hot patching refers to patch repairing the object to be repaired (such as VNF or VNFC in the embodiment of the present application) during its operation; patches are usually generated because the object to be repaired has defects, or the software version is upgraded or other situations require patch repair; when patch repair is required, the slice management system can receive the patch description file, or automatically obtain the patch description file, and then parse the patch description file to determine the VNF of the target network slice targeted by the patch description file, and the target VNF ​​component (Virtualised Network Function Component, VNFC) of the target VNF. The VNFC component is an internal component of the VNF, which can provide a subset of related functions for the VNF, and a single instance of the component is mapped 1:1 to a single virtualized container.

[0045] The patch description file is used to perform patch repairs on the target network slice, and each target network slice may include one or more VNFs. When patch repairing the network slice, there may be a situation where multiple VNFs need to be patched at the same time. For example, if VNF1 and VNF2 have an associated relationship, if VNF1 is patched, VNF2 may also need to be patched to cooperate with VNF1. Therefore, the patch description file may include patch programs for multiple VNFs. Optionally, in order to implement patch repairs for multiple VNFs at a time, the patch programs of the relevant multiple VNFs can be packaged into a TARS package as a patch description file. Specifically, a TARS package is a data packet obtained by encoding and processing using the TARS encoding protocol. The TARS encoding protocol is a data encoding and decoding rule that encodes data types such as integers, enumeration values, strings, sequences, dictionaries, and custom structures into a binary data stream according to certain rules.

[0046] The patch description file is a Patch Pack Each of the patches VNF Patches Specifically, the patch description file includes the target network slice Description of VNFC And VNFC VNFC Patch ; As a first example, the patch description file may include the following content:

[0047] Parameter 1. Patch package name acPatchName;

[0048] Parameter 2. Patch package version acVersion;

[0049] Parameter 3. Patch package path acPatchUrl;

[0050] Parameter 4. Patch package date acDate;

[0051] Parameter 5. Patch package provider acProvider;

[0052] Parameter 6. Number of VNF objects targeted by the patch package u32VNFObjNum,

[0053] Parameter 7. Patch package serial number and other information u32PatchSeqNumber;

[0054] Specifically, each VNF object number u32VNFObjNum (parameter 6) further includes the following:

[0055] Parameter 6.1 VNF type acVNFType;

[0056] Parameter 6.2 VNF version acVNFVersion;

[0057] Parameter 6.3 VNF patch version acPatchVersion;

[0058] Parameter 6.4VNFC object number u32VNFCObjNum;

[0059] Furthermore, parameter 6.4 includes the following:

[0060] Parameter 6.4.1 VNFC name,

[0061] Parameter 6.4.2 Number of patches required for VNFC u32Libpatchnum,

[0062] Parameter 6.4.3 VNFC patch;

[0063] Furthermore, parameter 6.4.3 includes the following:

[0064] Parameter 6.4.3.1 The source library name targeted by the patch acOrilibname;

[0065] Parameter 6.4.3.2 Patch library name acPatchlibname;

[0066] Parameter 6.4.3.3 Number of external variables that the patch depends on u32ExtvarsNumber;

[0067] Parameter 6.4.3.4 List of external variables that the patch depends on astExtvars;

[0068] Parameter 6.4.3.5 Number of external functions that the patch depends on u32ExtfuncsNumber;

[0069] Parameter 6.4.3.6 List of external functions that the patch depends on astExtfuncs;

[0070] Parameter 6.4.3.7: number of functions replaced by the patch u32FuncNumber;

[0071] Parameter 6.4.3.8 patch replacement function list astFuncReplace.

[0072] Optionally, the patch description file may be described in a language such as json format.

[0073] When parsing a patch description file, the slice management system determines the target VNF ​​corresponding to the parsed patch description file, and the target VNF ​​includes a target VNFC and a VNFC patch of the target VNFC.

[0074] Step 102, according to the preset slice blueprint, determine the first Internet Protocol IP address of the target VNF ​​and the second IP address of the target VNFC.

[0075] The slice blueprint is used to create a network slice. The slice blueprint describes the network slice subnet template that constitutes the network slice; the network slice subnet template describes the virtualized network function module descriptor (Virtualised Network Function Descriptor, VNFD) that constitutes the network slice subnet; VNFD is used to describe the configuration template of the deployment and operation behavior of a VNF, which is used in the VNF operation process and the life cycle management of the VNF instance. VNFD describes the VNFC included in the VNF, the first Internet Protocol (Internet Protocol, IP) address of the VNF (that is, the IP address of the main control module of the VNF), and the parameter information of the VNFC.

[0076] When the VNF is instantiated, the physical server where the VNFC virtual machine is located is recorded in the slice blueprint, that is, the second IP address of the VNFC is recorded; therefore, the network slice management system can determine the first IP address of the VNF and the second IP address of each VNFC of the VNF according to the slice blueprint, and then locate each VNF and VNFC. The slice blueprint determines the VNF and VNFC, ensuring the accuracy of the target VNF ​​and target VNFC. The patch repair process is successfully carried out; avoid invalid patch repair operations due to inaccurate target VNF ​​and target VNFC. do .

[0077] Step 103: Perform a patch repair on the target VNFC of the target VNF ​​according to the first IP address, the second IP address, and the VNFC patch.

[0078] After determining the first IP address, the slice management system sends a control instruction to the target VNF; the target VNF ​​is controlled to send a control instruction to the target VNFC according to the second IP address, and the target VNFC is controlled to perform patch repair according to the VNFC patch. Implementing Dynamics Patch fixes .

[0079] In an embodiment of the present application, the slice management system parses a patch description file, determines a target virtualized network function VNF, a target VNF ​​component VNFC of the target VNF, and obtains a VNFC patch of the target VNFC; determines a first Internet Protocol IP address of the target VNF ​​and a second IP address of the target VNFC according to a preset slice blueprint; performs patch repair on the target VNFC of the target VNF ​​according to the first IP address, the second IP address and the VNFC patch, realizes dynamic patch repair, and determines VNF and VNFC based on the slice blueprint to ensure the accuracy of the target VNF ​​and the target VNFC; avoids invalid patch repair operations due to inaccurate target VNF ​​and target VNFC; the embodiment of the present application solves the problem of increased difficulty in hot patch operations of 5G network slices in the prior art.

[0080] In an optional embodiment, the step of patching the target VNFC of the target VNF ​​according to the first IP address, the second IP address, and the VNFC patch includes:

[0081] According to the first IP address, a first patch repair indication is sent to the target VNF, instructing the target VNF ​​to obtain a target patch package from the slice management system according to the first patch repair indication, and instructing the target VNF ​​to perform a patch repair on the target VNFC according to the VNFC patch and the second IP address.

[0082] After the slice management system determines the first IP address, it sends a control instruction to the target VNF ​​according to the first IP address; it instructs the target VNF ​​to send a control instruction to the target VNFC according to the second IP address, and controls the target VNFC to perform patch repair according to the VNFC patch, thereby realizing dynamic patch repair.

[0083] In an optional embodiment, the VNFC patch includes a patch file of the first target VNF,

[0084] or

[0085] The VNFC patch includes a patch file of the first target VNF ​​and a patch file of the second target VNF; and the second target VNF ​​has a preset association relationship with the first target VNF.

[0086] That is to say, each target network slice may include one or more VNFs. When patching a network slice, there may be a situation where multiple VNFs need to be patched at the same time. For example, if VNF1 and VNF2 have a preset association relationship, if VNF1 is patched, VNF2 must also be patched accordingly to cooperate with VNF1. Therefore, the patch description file can include patch programs for multiple VNFs.

[0087] As a second example, see Figure 2 , Figure 2 An application process of the patch repair method is shown, wherein the slice management system can obtain the patch description file and the slice blueprint in advance, determine according to the patch description file that the target network slice includes the associated relationship VNF1 and VNF2, and then perform the following patch repair process; and in the following patch repair process, VNF1 and VNF2 can be repaired at the same time, wherein steps 11 to 14 are for repairing VNF1, and steps 21 to 24 are for repairing VNF2; wherein the repair steps for the two VNFs can be performed simultaneously;

[0088] Specifically, repairing VNF1 mainly includes the following steps:

[0089] In step 11, the slice management system sends a first patch repair indication to the VNF1 master control (i.e., the main control module); before step 11, the slice management system combines the slice blueprint to determine the deployed VNF version and date and other information, matches and finds the VNF1 and VNFC1 that need to be patched, as well as their IP addresses, and sends a first patch repair indication to the VNF1 master control.

[0090] Step 12: The VNF1 master controller obtains VNFC patch 1 and the IP address of VNFC1 according to the first patch repair instruction.

[0091] Step 13: The VNF1 master controller sends a first patch repair indication to VNFC1 according to the IP address of VNFC1.

[0092] Step 14: VNFC1 downloads VNFC patch 1 from the VNF1 master control and performs patch repair.

[0093] Repairing VNF2 mainly includes the following steps:

[0094] In step 21, the slice management system sends a first patch repair indication to the VNF2 master (i.e., the main control module); before step 21, the slice management system combines the slice blueprint to determine the deployed VNF version and date and other information, matches and finds the VNF2 and VNFC2 that need to be patched, as well as their IP addresses, and sends a first patch repair indication to the VNF2 master.

[0095] Step 22: The VNF2 master controller obtains the VNFC patch 2 and the IP address of VNFC2 according to the first patch repair instruction.

[0096] Step 23: The VNF2 master sends a first patch repair indication to VNFC2 according to the IP address of VNFC2.

[0097] Step 24, VNFC2 downloads VNFC patch 2 from the VNF2 master control and performs patch repair.

[0098] In the communication service mode using network slicing, the method of hot patching network elements through the operation and maintenance center (OMC) in the prior art is likely to become inefficient or even infeasible; in the embodiment of the present application, hot patch repair of network elements is performed from the slice management system, and hot patch repair is performed based on the 5G network slice blueprint and patch description file, which makes full use of the role of the slice management system and the slice blueprint, which is of great significance and role in the operation and maintenance of network slicing.

[0099] In an embodiment of the present application, the slice management system parses a patch description file, determines a target virtualized network function VNF, a target VNF ​​component VNFC of the target VNF, and obtains a VNFC patch of the target VNFC; determines a first Internet Protocol IP address of the target VNF ​​and a second IP address of the target VNFC according to a preset slice blueprint; performs patch repair on the target VNFC of the target VNF ​​according to the first IP address, the second IP address, and the VNFC patch to achieve dynamic patch repair, and determines the VNF and VNFC based on the slice blueprint to ensure the accuracy of the target VNF ​​and the target VNFC; avoids invalid patch repair operations due to inaccurate target VNF ​​and target VNFC.

[0100] See also Figure 3 The embodiment of the present application also provides a patch repair method, which is applied to a target virtualized network function VNF, and the method includes:

[0101] Step 301: Receive a first patch repair indication sent by a slice management system through a first Internet Protocol IP address, and obtain a second IP address carried in the first patch repair indication.

[0102] Among them, the second IP address is the IP address of the target VNFC; the second IP address is the IP address of the target VNFC determined by the slice management system according to the preset slice blueprint; the target VNFC is obtained after the slice management system parses the patch description file.

[0103] Among them, hot patching refers to patching the repair object during the operation of the repaired object; patches are usually generated because the repaired object has defects, or the software version is upgraded or other situations require patch repair; when patch repair is required, the slice management system can receive the patch description file, or automatically obtain the patch description file, and then parse the patch description file to determine the VNF of the target network slice targeted by the patch description file, and the target VNFC of the target VNF. The VNFC component is an internal component of the VNF, which can provide a subset of related functions for the VNF, and a single instance of the component is mapped 1:1 to a single virtualized container.

[0104] The patch description file is used to perform patch repair on the target network slice. Each target network slice may include one or more VNFs. When patch repairing a network slice, there may be a situation where multiple VNFs need to be patched at the same time. For example, if VNF1 and VNF2 have an associated relationship, if VNF1 is patched, VNF2 may also need to be patched to cooperate with VNF1. Therefore, the patch description file may include the patch programs of multiple VNFs. Optionally, in order to implement patch repair on multiple VNFs at one time, the patch programs of multiple related VNFs can be packaged into a TARS package as a patch description file.

[0105] When parsing a patch description file, the slice management system determines the target VNF ​​corresponding to the parsed patch description file, and the target VNF ​​includes a target VNFC and a VNFC patch of the target VNFC.

[0106] The slice blueprint is used to create a network slice. The slice blueprint describes the network slice subnet template that constitutes the network slice. The network slice subnet template describes the virtualized VNFD that constitutes the network slice subnet. VNFD is used to describe the configuration template of the deployment and operation behavior of a VNF, which is used in the VNF operation process and the life cycle management of the VNF instance. VNFD describes the VNFC included in the VNF, the first IP address of the VNF (i.e., the IP address of the main control module of the VNF), and the parameter information of the VNFC.

[0107] When the VNF is instantiated, the physical server where the virtual machine of the VNFC is located is recorded in the slice blueprint, that is, the second IP address of the VNFC is recorded; therefore, the network slice management system can determine the first IP address of the VNF and the second IP address of each VNFC of the VNF according to the slice blueprint, and then locate each VNF and VNFC. Since the network slice changes dynamically according to the slice blueprint during operation, the VNF and VNFC are determined based on the slice blueprint to ensure the accuracy of the target VNF ​​and target VNFC, so that the patch repair process is successfully carried out; avoid invalid patch repair operations due to inaccurate target VNF ​​and target VNFC.

[0108] The slice management system sends a first patch repair indication to the target VNF ​​according to the first IP address; the target VNF ​​receives the first patch repair indication through the first address, obtains the second IP address carried in the first patch repair indication, and performs patch repair.

[0109] Step 302: Obtain the VNFC patch in the patch description file from the slice management system according to the first patch repair indication, and perform a patch repair on the target VNFC according to the VNFC patch and the second IP address.

[0110] The target VNF ​​obtains the VNFC patch in the patch description file from the slice management system according to the first patch repair indication; and controls the target VNFC to perform patch repair according to the VNFC patch and the second IP address.

[0111] In an optional embodiment, the step of patching the target VNFC according to the VNFC patch and the second IP address includes:

[0112] According to the second IP address, a second patch repair indication is sent to the target VNFC, instructing the target VNFC to obtain a VNFC patch from the target VNF ​​according to the second patch repair indication, and instructing the target VNFC to perform a patch repair according to the VNFC patch.

[0113] Refer to step 13 and step 14, step 23 and step 24 in the second example; the target VNF ​​receives the first patch repair indication through the first IP address, obtains the second IP address carried in the first patch repair indication, and obtains the VNFC patch; sends the second patch repair indication to the target VNFC through the second IP address, and the target VNFC performs patch repair according to the VNFC patch.

[0114] In an optional embodiment, the VNFC patch includes a first identifier of a source library of the patch, a second identifier of a target library, and a replacement function list; the first identifier is, for example, parameter 6.4.3.1 in the first example, the second identifier is, for example, parameter 6.4.3.2 in the first example, and the replacement function list is, for example, parameter 6.4.3.8 in the first example.

[0115] The step of instructing the target VNFC to perform patch repair according to the VNFC patch includes:

[0116] Instruct the target VNFC to determine a first function address of the replacement function list in the source library according to the first identifier and the replacement function list, and to determine a second function address of the replacement function list in the target library according to the second identifier and the replacement function list;

[0117] Instruct the target VNFC to replace the first function address with the second function address.

[0118] In combination with the first example, the target VNFC is instructed to find the function address to be replaced in the executable file (such as ELF file) of the target VNFC according to the source library name acOrilibname, that is, to replace the first function address of the function list in the source library.

[0119] Find a new function address in the new library acPatchlibname, that is, replace the second function address in the function list in the target library, and then instruct the target VNFC to replace the first function address with the second function address, and use the new function address to replace the old function address in the executable file. In this way, the function address is replaced based on the replacement function list in the patch description file without unloading the dynamic library and then loading the new dynamic library, which simplifies the patch repair process and makes the patch repair faster and more efficient.

[0120] In an embodiment of the present application, a first patch repair indication sent by a slice management system is received through a first IP address, and a second IP address carried in the first patch repair indication is obtained; the VNFC patch in the patch description file is obtained from the slice management system, and the target VNFC is patched according to the VNFC patch and the second IP address; based on the first IP address, the second IP address and the VNFC patch, the target VNFC is patched to achieve dynamic patch repair, and the VNF and VNFC are determined based on the slice blueprint to ensure the accuracy of the target VNF ​​and the target VNFC; invalid patch repair operations are avoided due to inaccurate target VNF ​​and target VNFC.

[0121] See also Figure 4The embodiment of the present application also provides a patch repair method, which is applied to a component VNFC of a target virtualized network function VNF, and the method includes:

[0122] Step 401, receiving the second patch repair indication sent by the target VNF ​​through the second Internet Protocol IP address; the second IP address is determined by the slice management system according to the preset slice blueprint and sent to the target VNF.

[0123] Among them, the second IP address is the IP address of the target VNFC of the target VNF; the second IP address is the IP address of the target VNFC determined by the slice management system according to the preset slice blueprint; the target VNFC is obtained after the slice management system parses the patch description file.

[0124] Among them, hot patching refers to patching the repair object during the operation of the repaired object; patches are usually generated because the repaired object has defects, or the software version is upgraded or other situations require patch repair; when patch repair is required, the slice management system can receive the patch description file, or automatically obtain the patch description file, and then parse the patch description file to determine the VNF of the target network slice targeted by the patch description file, and the target VNFC of the target VNF. The VNFC component is an internal component of the VNF, which can provide a subset of related functions for the VNF, and a single instance of the component is mapped 1:1 to a single virtualized container.

[0125] The patch description file is used to perform patch repair on the target network slice. Each target network slice may include one or more VNFs. When patch repairing a network slice, there may be a situation where multiple VNFs need to be patched at the same time. For example, if VNF1 and VNF2 have an associated relationship, if VNF1 is patched, VNF2 may also need to be patched to cooperate with VNF1. Therefore, the patch description file may include the patch programs of multiple VNFs. Optionally, in order to implement patch repair on multiple VNFs at one time, the patch programs of multiple related VNFs can be packaged into a TARS package as a patch description file.

[0126] When parsing a patch description file, the slice management system determines the target VNF ​​corresponding to the parsed patch description file, and the target VNF ​​includes a target VNFC and a VNFC patch of the target VNFC.

[0127] The slice blueprint is used to create a network slice. The slice blueprint describes the network slice subnet template that constitutes the network slice. The network slice subnet template describes the virtualized VNFD that constitutes the network slice subnet. VNFD is used to describe the configuration template of the deployment and operation behavior of a VNF, which is used in the VNF operation process and the life cycle management of the VNF instance. VNFD describes the VNFC included in the VNF, the first IP address of the VNF (i.e., the IP address of the main control module of the VNF), and the parameter information of the VNFC.

[0128] When the VNF is instantiated, the physical server where the virtual machine of the VNFC is located is recorded in the slice blueprint, that is, the second IP address of the VNFC is recorded; therefore, the network slice management system can determine the first IP address of the VNF and the second IP address of each VNFC of the VNF according to the slice blueprint, and then locate each VNF and VNFC. Since the network slice changes dynamically according to the slice blueprint during operation, the VNF and VNFC are determined based on the slice blueprint to ensure the accuracy of the target VNF ​​and target VNFC, so that the patch repair process is successfully carried out; avoid invalid patch repair operations due to inaccurate target VNF ​​and target VNFC.

[0129] The slice management system sends a first patch repair indication to the target VNF ​​according to the first IP address. The target VNF ​​receives the first patch repair indication through the first address, obtains the second IP address carried in the first patch repair indication, performs patch repair, and obtains the VNFC patch in the patch description file from the slice management system according to the first patch repair indication; and sends a second patch repair indication to the target VNFC according to the second IP address.

[0130] The target VNFC receives the second patch repair indication sent by the target VNF ​​through the second IP address, and performs patch repair.

[0131] Step 402: Obtain a VNFC patch from the target VNF ​​according to the second patch repair indication, and perform patch repair according to the VNFC patch; wherein the VNFC patch is obtained by the target VNF ​​from the slice management system, and the VNFC patch is obtained by the slice management system from the patch description file.

[0132] In combination with step 13 and step 14, step 23 and step 24 in the second example, the target VNFC obtains the VNFC patch from the target VNF ​​according to the second patch repair indication, and then performs patch repair according to the VNFC patch to implement dynamic patch repair.

[0133] In an optional embodiment, the VNFC patch includes a first identifier of a source library of the patch, a second identifier of a target library, and a replacement function list; the first identifier is, for example, parameter 6.4.3.1 in the first example, the second identifier is, for example, parameter 6.4.3.2 in the first example, and the replacement function list is, for example, parameter 6.4.3.8 in the first example.

[0134] The step of performing patch repair according to the VNFC patch includes:

[0135] Determine, according to the first identifier and the replacement function list, a first function address of the replacement function list in the source library, and, according to the second identifier and the replacement function list, determine a second function address of the replacement function list in the target library;

[0136] The first function address is replaced by the second function address.

[0137] In combination with the first example, according to the source library name acOrilibname, the function address that needs to be replaced is found in the executable file (such as ELF file) of the target VNFC, that is, the first function address of the replacement function list in the source library is replaced.

[0138] Find the new function address in the new library acPatchlibname, that is, replace the second function address in the function list in the target library, then replace the first function address with the second function address, and use the new function address to replace the old function address in the executable file. In this way, the function address is replaced based on the replacement function list in the patch description file without unloading the dynamic library and then loading the new dynamic library, which simplifies the patch repair process and makes the patch repair faster and more efficient.

[0139] In an embodiment of the present application, a second patch repair indication sent by the target VNF ​​is received through a second IP address; a VNFC patch is obtained from the target VNF ​​according to the second patch repair indication, and a patch repair is performed according to the VNFC patch to implement dynamic patch repair; and because the network slice dynamically changes according to the slice blueprint during operation, the VNF and VNFC are determined based on the slice blueprint to ensure the accuracy of the target VNF ​​and the target VNFC, thereby avoiding invalid patch repair operations due to inaccurate target VNF ​​and target VNFC.
