The above described objects, features and advantages of the embodiments of the present invention will become more apparent and understood. The technical solution is described in further detail.

 The embodiment of the invention provides a network resource allocation method, an orchestrator and a manager in a virtual network function, which can dynamically adjust the available resources of the NS after the NS is generated, and ensure the availability and continuity of the NS.

 The method and the device in the embodiment of the present invention propose that, in the FV environment, when the NS is generated, an NSAI is added to the NSD to indicate that the NS can use the resource information exceeding the subscription value, that is, the information of the standby resource, in the operator and When the customer signs up, determine the time limit, type and quantity of the spare resources.

 FIG. 1 is a flowchart of a method for allocating network resources in a virtual network function according to Embodiment 1 of the present invention, where the method includes:

 Step S101: NSD sent by the OSS or the BSS; the NSD includes the subscription resource information of the NS and the NSAI information; the NSAI is used to indicate the information of the standby resource of the NS;

 Step S102: Obtain performance abnormal data of the VNF that is currently abnormal.

 Step S103: When it is determined that the V F is performance overload or performance is too low, according to the contract resource information of the NS, the information of the standby resource indicated by the NSAI, and the performance abnormal data of the V F, a corresponding NSRRHP is formulated;

 Step S104: Send the NSRRHP to the VNFM and the VIM respectively.

 According to the method of the embodiment of the present invention, when the NSAL for indicating the information about the standby resource of the NS is added, the abnormality alarm of the performance overload or the performance of the VF is determined according to the contract resource information of the NS and the NSAI indication. The information of the standby resource and the performance abnormal data of the VNF are used to formulate a corresponding NSRRHP, and dynamically adjust the available resources of the NS for the VNF to ensure the availability and continuity of the NS.

 The method of the first embodiment of the present invention is applied to the scenario of Orchestrator decision making.

In this scenario, V FM is responsible for analyzing and judging the abnormal alarms reported by the EMS (Element Management System) to determine whether the current NS resources are too small or too much. If not, take other fault management mechanisms. Recover; if yes, send the exception alert to Orchestrator Process it.

 In this embodiment, the Orchestrator makes a reservation resource processing decision based on the V F anomaly type and the NSAI information, and delivers the corresponding action to V FM and VIM.

 The method described in Embodiment 1 will be described in detail below with reference to FIG. 2 and Embodiment 2 of the present invention. 2 is a signaling flowchart of a method for allocating network resources in a V F according to Embodiment 2 of the present invention. As shown in FIG. 2, the method includes the following steps:

 Step S201: The 0SS/BSS sends the NSD to the Orchestrator. The NSD includes the NS subscription resource information and the NSAI information.

 The NSAI information is used to indicate the condition of the standby resource of the NS, and the standby resource is a resource that the NS can use exceeding the subscription value. The contract value refers to the number of the NS contract resources.

 In the embodiment of the present invention, when the operator signs a contract with the client, the information of the resource required for the normal use of the NS is determined, which is also referred to as the contracted resource information. At the same time, it can also determine the information of the resources that NS can use, which is the backup resource information.

 Correspondingly, the operator deploys the network resources, and pre-defines a part of the resources as reserved resources. The reserved resources are used to provide backup resources for the VNF in the event that the VNF causes a network failure due to a shortage of NS resources. For example, you can set the resource deployment as: 90~95% for operational resources and 5~10% for reserved resources.

 Specifically, in the embodiment of the present invention, an NSAL is added to the NSD to indicate the situation of the standby resource. The NSD containing the NSAI is sent to Orchestrator by 0SS/BSS.

 It should be noted that the NSAI information may include at least: an NSID, an alternate resource usage time limit, a spare resource type, and a quantity.

 Specifically, the NSID is used to identify the NS, and is used to indicate the NS to which the standby resource is applicable.

 The usage time limit of the standby resource, which is used to indicate the maximum time that the standby resource can be used from the time of opening. For example, it can be hours or days, etc.

 It should be noted that the backup resources are mainly used when the customer suddenly needs a lot of resources, and generally the duration of this situation is not too long. For example, if customers need a lot of resources for a long time, they will usually sign up for a large amount of traffic. Therefore, the occupation time of the standby resource is generally not too long, so that the backup resource is not occupied for a long time after being opened, and the backup resource is released in time to meet the customer demand, so as to avoid waste of resources.

The type and quantity of the standby resource, which is used to indicate the type of the spare resource included in the NSAI, and the corresponding number of each type of the spare resource. For example, the types of alternate resources can be: Software resources and hardware resources. The software resources may include bandwidth resources, virtual link resources, and the like; the hardware resources may include VM resources, PF resources, and the like. The NSAI information may include multiple types of spare resources, and respectively set the number corresponding to each type of spare resources. For example, for a VF resource, assuming that its subscription value is 30 MHz, the maximum number that is expected to grow in the NS is 100 MHz. The NSAI information includes the following information: The spare resource type is a VF resource, and the quantity is 100 MHz.

 It should be noted that all the information included in the NSAI can be specifically set by the customer according to actual needs when signing the contract.

 Step S202: The EMS obtains the running performance of each VNF in the NS.

 Specifically, the EMS can periodically monitor the running performance of each V F in the NS. Alternatively, the EMS can periodically receive the running performance information reported by each VNF in the NS.

 The operating performance of the V F may include: bandwidth usage, throughput, delay, and the like.

 Step S203: When the EMS finds a performance abnormality alarm of the VNF, the performance abnormality alarm information of the VNF is reported to the VFM.

 Step S204: After receiving the performance abnormality alarm information of the VNF reported by the EMS, the VFM determines whether the performance is overloaded according to the performance abnormality alarm information. If yes, the process proceeds to step S205; if not, the performance is abnormal according to the normal process. The alarm is processed.

 Specifically, after receiving the performance abnormality alarm information of the VNF, the VFM analyzes and determines the abnormal alarm to determine whether the abnormality is caused by the NS performance overload, and whether the NS resource is added to solve the problem, if yes, then The VNF starts the standby resource and solves the abnormal alarm by adding NS resources.

 Specifically, the abnormal alarm information includes performance abnormal data, and is analyzed according to the performance abnormal data. When the resource usage rate of the VNF is higher than a preset first threshold, the performance abnormal alarm information may be determined as the VNF performance. overload.

 Step S205: The VNFM sends an NSRRR message to the Orchestrator. The NSRRR includes the network resource operation identifier and the performance abnormal data of the VNF.

 Specifically, the NSRRR may include a network resource operation identifier. When the VNFM determines that the current abnormality is a performance overload, and the NS resource needs to be enabled for the VNF, the operation identifier of the network resource of the NSRRR may be set to Increasing, meaning to enable Alternate resources.

 Step S206: The Orchestrator receives the NSRRR message sent by the VNFM, and determines that the current abnormality is a performance overload according to the network resource operation identifier, and the Orchestrator determines according to the NS subscription resource information, the NSAI indicated alternate resource information, and the VNF performance abnormal data. The network service reserves the resource processing policy NSRRHP, and proceeds to steps S207a and S207b.

Specifically, the information about the subscription resource according to the NS and the information about the standby resource indicated by the NSAI And the performance abnormal data of the VNF, the corresponding NSRRHP is formulated to include:

 Based on the performance exception data of the V F included in the NSRRR message, the Orchestrator determines the type of the resource that is currently overloaded with the performance, that is, it determines the current type of resources that are in short supply and causes an abnormal report.

 The Orchestrator queries the information of the alternate resource indicated by the NSAI to obtain the number of spare resources of the type in which the performance overload occurs. In other words, the Orchestrator queries the alternate resource information indicated by the NSAI to determine which types of backup resources can be enabled for the VNF.

 At the same time, the Orchestrator also queries the contracted resource information of the NS to obtain the number of subscriptions of the resource of the type that currently has performance overload.

 The Orchestrator formulates the NSRRHP as: enabling the backup resource of the type in which the performance overload is currently occurring, such that the number of available resources of the type is the number of spare resources of the type plus the number of subscriptions of the type.

 Specifically, it is assumed that the data of the NS performance overload in the NSRRR message received by the current Orchestrator indicates that the VNF resource required by the VNF is 80 MHz, and the VNF subscription value of the client is only 30 MHz. The Orchestrator can know from the NSAI received from the OSS/BSS in step S201 that the V F backup resource of the client is 100 MHz.

 Orchestrator sets NSRRHP to: Enable V F standby resources for the V F, so that the number of available resources of the V F is 130 MHz to solve the current fault.

 It should be noted that, in the second embodiment of the present invention, the VFM performs analysis and judgment according to the performance abnormality alarm information of a VF reported by the EMS. When it is determined that the abnormal alarm is a performance overload, the network resource operation identifier included in the NSRRR is determined. Tell Orchestrator that the exception is a performance overload and need to turn on alternate resources for the VNF.

 Further, in other embodiments of the present invention, the method may further include: sending, by the VFM, the performance abnormality alarm information of a certain V F reported by the EMS to the Orchestrator. The Orchestrator analyzes and determines the performance abnormality alarm information. When the resource usage rate included in the information is higher than the preset first threshold, the Orchestrator determines that the V F is a performance overload, and needs to open the standby resource for the VNF.

 Step S207: The Orchestrator sends the NSRRHP message to the VNFM, and proceeds to step S208a. The NSRRHP message includes policy information for expanding the VNF resource.

The VF resource refers to the software resources of the NS, for example, bandwidth resources, virtual link resources, and the like. Step S207b: The Orchestrator sends the NSRRHP message to the VIM, and proceeds to step S208b. The NSRRHP message includes the NFVI (FV Infrastructure, Network Function Virtualization Infrastructure). Policy information for resource expansion.

 The FVI resource refers to the hardware resources of the NS, for example, VM resources, PNF resources, and the like.

 Step S208a: After receiving the NSRRHP message, the VNFM performs an extended operation on the VNF resource according to the policy in the NSRRHP message, that is, the standby resource of the VNF is enabled.

 Step S208b: After receiving the NSRRHP message, the VIM performs an extended operation on the FVI resource according to the policy in the NSRRHP message, that is, the standby resource of the NFVI is enabled.

 Through the above method, the customer can not only use the normal use resources specified in the contract, but also use the spare resources specified in the NSAI, thereby eliminating the overload abnormality of the NS, avoiding the abnormal interruption of the service, and satisfying the use requirements of the customer. Improve the usability and continuity of NS.

 The method of the embodiment of the present invention further includes: releasing the standby resource occupied by the VNF after the NS overload abnormality of the VNF is eliminated or the usage time of the standby resource is reached, in order to avoid the NS resource waste and the use of the backup resource.

 Still in conjunction with FIG. 2, after steps S208a and S208b, the method further includes:

 Step S209: The EMS obtains the running performance of each VNF in the NS.

 Specifically, the EMS can periodically monitor the running performance of each V F in the NS. Alternatively, the EMS can periodically receive the running performance information reported by each VNF in the NS.

 The operating performance of the V F may include: bandwidth usage, data throughput, latency, and the like.

 Step S210: When the EMS finds a performance abnormality alarm of the VNF, the performance abnormality alarm information of the VNF is reported to the VFM.

 Step S211: After receiving the performance abnormality alarm information of the VF reported by the EMS, the VFM determines whether it is necessary to release the standby resource of the NS for the VF. If the release is required, the process proceeds to step S212; otherwise, the performance is abnormal according to the normal procedure. The alarm is processed.

 Specifically, after receiving the performance abnormality alarm information of the VF reported by the EMS, the VNFM determines whether the performance is too low and the standby resource is turned on according to the performance abnormality alarm information. If yes, the process proceeds to step S212; if not, the The normal process handles this performance anomaly alarm.

 Specifically, after receiving the performance abnormality alarm information of the VNF, the VNFM analyzes the abnormal alarm to determine whether the abnormality is caused by the NS performance of the VF being too low, for example, analyzing and judging according to the performance abnormal data in the performance abnormal alarm information. When the resource usage of the VF is lower than the preset second threshold, it may be determined that the alarm is too low for the VNF performance.

Then, if it is further determined whether the standby resource is enabled before the VNF, if it is turned on, it is determined that the standby resource of the NS needs to be released for the VF; if not, the performance abnormality alarm is performed according to a normal process. deal with.

 Specifically, the VFM determines whether the standby resource is enabled before the VNF according to the NS performance parameter of the VNF and the parameter information in the NSAI.

 For example, by querying the NS performance parameter of the V F , the V FM determines that the V F subscription value is only 30 MHz, but the actual available resource value of the VNF is currently 130 MHz. Meanwhile, the NS has the standby VNF resource of 100 MHz. From this it can be determined that the VNF has opened the standby resource.

 Since the current resource usage of the VNF is too low, it can be known that the VNF does not need to continue to occupy the standby resource, and thus the standby resource can be released to avoid resource waste.

 Step S212: The VNFM sends an NSRRR message to the Orchestrator. The NSRRR includes the network resource operation identifier and the performance abnormal data of the VNF.

 Specifically, the NSRRR may include a network resource operation identifier. When the VNFM determines that the current abnormality is too low and needs to release the NS standby resource for the VNF, the operation identifier of the network resource of the NSRRR may be set to Decreasing, meaning Release the alternate resource.

 Step S213: The Orchestrator receives the NSRRR message sent by the VNFM, determines that the network resource operation identifier determines that the current abnormality is too low, and the Orchestrator formulates the contract resource information according to the NS, the information of the standby resource indicated by the NSAI, and the performance abnormal data of the VNF. The corresponding network service reservation resource processing policy NSRRHP proceeds to steps S214a and S214b.

 The formulating the corresponding NSRRHP according to the contract resource information of the NS, the information of the standby resource indicated by the NSAI, and the performance abnormal data of the VNF includes:

 The Orchestrator determines the type of the resource that is currently under-performing according to the performance abnormality data of the V F included in the NSRRR message, that is, to determine which types of resources are currently used, and the usage rate is too low, causing an abnormal alarm.

 The Orchestrator queries the contracted resource information of the NS to obtain the number of subscriptions of the currently underperforming type of resources.

 When the number of available resources of the type is greater than the number of subscriptions of the type, it is determined that the resource of the type has opened the standby resource.

 The Orchestrator formulates the NSRRHP as: releasing the spare resources of the type such that the number of available resources of the type is a subscription value of the type.

Specifically, it is assumed that the NS performance of the NSRRR message received by the current Orchestrator is too low, and the VNF resource required by the VNF is only 10 MHz, and the VNF resource currently available to the client is 130 MHz, and the VNF subscription value is 30MHz. Orchestrator knows through NSAI that the customer's VNF The spare resource is 100MHz.

 Orchestrator formulates an alternate resource processing strategy, and determines to release the VNF backup resource for the VNF, so that the VNF itself can meet the current requirements to avoid resource waste.

 It should be noted that, in the second embodiment of the present invention, the VFM may perform analysis and judgment according to the performance abnormality alarm information of a certain VNF reported by the EMS, and when it is determined that the abnormal alarm is too low, the network resources included in the NSRRR are included. The operation identifier tells Orchestrator that the exception is a performance overload and needs to release spare resources for the VNF.

 Further, in other embodiments of the present invention, the method may further include: sending, by the VFM, the performance abnormality alarm information of a certain V F reported by the EMS to the Orchestrator. The performance abnormality alarm information is analyzed and judged by the Orchestrator. When the resource usage rate included in the information is lower than the preset second threshold, the Orchestrator determines that the V F is too low and needs to release the standby resource for the VNF.

 Step S214a: The Orchestrator sends the NSRRHP message to the VNFM, and proceeds to step S215a. The NSRRHP message includes policy information for releasing the VNF backup resource.

 Step S214b: The Orchestrator sends the NSRRHP message to the VIM, and proceeds to step S215b. The NSRRHP message includes policy information for releasing the NFVI backup resource.

 Step S215a: After receiving the NSRRHP message, the VNFM performs a release operation on the VNF resource according to the policy in the NSRRHP message.

 Step S215b: After receiving the NSRRHP message, the VIM performs release of the FVI resource according to the policy in the NSRRHP message.

 Through the above method, when the customer's subscription value can meet the running requirement, the standby resource occupied by the customer is released, so as to avoid waste of resources.

 Further, in the method of the embodiment of the present invention, the Orchestrator may also initiate a release operation of the standby resource.

 Specifically, the Orchestrator determines whether the currently used standby resource usage time exceeds the usage time of the standby resource according to the usage time limit of the NSAI information in the NSAI information. If the usage exceeds, the Orchestrator actively formulates a reserved resource processing policy, and releases the spare part. Resources. FIG. 3 is a flowchart of a method for allocating network resources in a virtual network function V F according to Embodiment 3 of the present invention. As shown in FIG. 3, the method may include the following steps:

 Step S301: Obtain performance abnormal data of the VNF in which the abnormality is currently occurring;

Step S302: Receive NSAI information sent by Orchestrato; the NSAI is used to indicate the NS Information about alternate resources;

 Step S303: When it is determined that the V F is performance overload or is too low, according to the subscription resource information of the NS, the information of the standby resource indicated by the NSAI, and the performance abnormal data of the VNF, formulating a corresponding NSRRHP;

 Step S304: Send the NSRRHP to the VIM.

 In the method of the embodiment of the present invention, when the NSAL for indicating the information about the standby resource of the NS is added to determine the abnormality alarm of the performance overload or the performance of the VF, the NSAI indicates the subscription resource information and the NSAI indicates the standby. The information of the resource and the performance abnormal data of the VNF are formulated, and the corresponding NSRRHP is formulated, and the available resources of the NS are dynamically adjusted for the VNF to ensure the availability and continuity of the NS.

 The method of Embodiment 3 of the present invention is applied to a scenario of V FM decision.

 In this scenario, if V FM is, the overload alarm is sent to Orchestrator for processing. In this embodiment, the VNFM is responsible for analyzing and judging the overload alarm reported by the EMS, and determining whether the current NS resource shortage is caused. If not, the other fault management mechanism is used for recovery; if yes, according to the abnormal type of the VNF and The NSAI information is made to reserve resource processing decisions and is sent to VIM to perform the corresponding actions.

 The method described in Embodiment 2 will be described in detail below with reference to FIG. 4 and Embodiment 4 of the present invention. 4 is a signaling flowchart of a method for allocating network service resources according to Embodiment 4 of the present invention. As shown in FIG. 4, the method includes the following steps:

 Step S401: The OSS/BSS sends the NSD to the Orchestrator. The NSD includes the contracted resource information and the NSAI information of the NS.

 Step S402: The EMS obtains the running performance of each VNF in the NS.

 Specifically, the EMS can periodically monitor the running performance of each V F in the NS. Alternatively, the EMS can periodically receive the running performance information reported by each VNF in the NS.

 The operating performance of the V F may include: bandwidth usage, data throughput, latency, and the like.

 Step S403: When the EMS finds a performance abnormality alarm of the VNF, the performance abnormality alarm information of the VNF is reported to the VNFM, and the abnormal alarm information includes the performance abnormality data.

 Step S404: After receiving the performance abnormality alarm information of the VNF reported by the EMS, the VNFM determines whether the performance is overloaded according to the performance abnormality data. If yes, the process proceeds to step S405; if not, the performance abnormality alarm is performed according to a normal process. deal with.

After receiving the performance abnormality alarm information of the VNF, the VNFM analyzes and determines the abnormal alarm to determine whether the abnormality is caused by the NS overload, whether it can be solved by adding the NS resource, and if so, the VF Enable the standby resource and solve the abnormal alarm by adding NS resources.

 Specifically, when the abnormal alarm information is that the resource usage rate is higher than a preset first threshold, determining that the VNF is a performance overload.

 Step S405: The VNFM sends a request message to the Orchestrator for requesting to acquire the NSAI information, and receives a response message including the NSAI information returned by the Orchestrator.

 Step S406: The VNFM establishes a corresponding NSRRHP according to the contract resource information of the NS, the information of the standby resource indicated by the NSAI, and the performance abnormal data of the VNF, and proceeds to step S407.

 In the third embodiment of the present invention, the VNFM determines, according to the data information of the NS performance overload of the VNF, which types of resources of the VNF are scarce, resulting in an abnormal alarm. At the same time, the VNFM determines which types of spare resources can be enabled for the V F based on the availability of the alternate resources in the NSAI information received from Orchestrator. Then, the VNFM formulates an alternate resource processing strategy, and makes a decision to open the standby resource of the type that is included in the NSAI information and the V F is in short supply.

 Specifically, the formulating the corresponding NSRRHP according to the subscription resource information of the NS, the information of the standby resource indicated by the NSAI, and the performance abnormal data of the VNF includes:

 The VNFM determines the type of resource that is currently experiencing performance overload based on the performance anomaly data of the VNF. Querying the information of the standby resource indicated by the NSAI, obtaining the quantity of the spare resource of the type; querying the subscription resource information of the NS, and obtaining the subscription quantity of the type.

 The NSRRHP is formulated to enable the type of spare resources such that the number of available resources of the type is the number of spare resources of the type plus the number of subscriptions of the type.

 Assume that the current VNFM determines that the NS performance overload data indicates that the VNF required for the VNF is 80 MHz, and the VNF subscription value of the customer is only 30 MHz. VNFM knows through NSAI that the customer's VNF backup resource is 100MHz.

 Then, the VNFM formulates an alternate resource processing strategy, and determines to enable the VNF backup resource for the V F, so that the VNF can have a 130 MHz resource to solve the current fault.

 Step S407: The VNFM sends the NSRRHP message to the VIM, and proceeds to step S408b.

The NSRRHP message includes policy information for extending FVI resources.

 Step S408a: The VNFM performs an extended operation on the VNF backup resource, that is, a backup resource for enabling the VNF.

 Step S408b: After receiving the NSRRHP message, the VIM performs an extended operation on the FVI backup resource according to the policy in the NSRRHP message, that is, the FVI standby resource is enabled.

Through the above method, the customer can not only use the normal use resources specified at the time of signing, but also use The standby resources specified in the NSAI can eliminate the overload abnormality of the NS, avoid the abnormal interruption of the service, meet the customer's use requirements, and improve the availability and continuity of the NS.

 In order to avoid the waste of NS resources and the use of resources of other VNFs, the method of the embodiment of the present invention further includes: releasing the standby resources occupied by the VNF after the NS overload abnormality of the VNF is eliminated or the usage time of the standby resource is reached.

 Still referring to FIG. 4, after steps S408a and S408b, the method further includes:

 Step S409: The EMS obtains the running performance of each VNF in the NS.

 Specifically, the EMS can periodically monitor the running performance of each V F in the NS. Alternatively, the EMS can periodically receive the running performance information reported by each VNF in the NS.

 The operating performance of the V F may include: bandwidth usage, data throughput, latency, and the like.

 Step S410: When the EMS finds a performance abnormality alarm of the VNF, the performance abnormality alarm information of the VNF is reported to the VFM.

 Step S411: After receiving the performance abnormality alarm information of a certain V F reported by the EMS, the V FM determines whether the performance is too low. If yes, the process goes to step S412; otherwise, the performance abnormality alarm is processed according to a normal process.

 Specifically, after receiving the performance abnormality alarm information of the VF reported by the EMS, the VFM first determines whether the alarm is an alarm whose VNF performance is too low, and if yes, further determines whether the standby resource is enabled before the VNF; , the performance exception alarm is processed according to the normal process.

 Specifically, the VNFM analyzes the performance abnormality alarm information of the VNF. When the resource usage rate of the V F is lower than a preset second threshold, the alarm may be determined to be an alarm that the VNF performance is too low.

 If it is further determined whether the standby resource is enabled before the VNF, if it is turned on, it is determined that the standby resource of the NS needs to be released for the V F; if not, the performance abnormality alarm is processed according to a normal procedure.

 Specifically, the VNFM determines whether the standby resource is enabled before the VNF according to the NS performance parameter of the VNF and the parameter information in the NSAI.

 For example, by querying the NS performance parameter of the V F, the VNFM determines that the V F subscription value is only 30 MHz, but the actual available resource value of the VNF is currently 130 MHz. Meanwhile, the NS has a standby VNF resource of 100 MHz. From this it can be determined that the VNF has opened the standby resource.

 Since the current resource usage of the VNF is too low, it can be known that the VNF does not need to continue to occupy the standby resource, and thus the standby resource can be released to avoid resource waste.

Step S412: The VNFM sends a request message to the Orchestrator for requesting acquisition of the NSAI information; Receives a response message including NSAI information returned by Orchestrator.

 Step S413: The VFM formulates a corresponding NSRRHP according to the subscription resource information of the NS, the information of the standby resource indicated by the NSAI, and the performance abnormality data of the VNF, and proceeds to step S414.

 The formulating the corresponding NSRRHP according to the contract resource information of the NS, the information of the standby resource indicated by the NSAI, and the performance abnormal data of the VNF includes:

 According to the performance abnormal data of the VNF, the type of the resource that is currently under-performing is determined.

 Querying the subscription resource information of the NS, and obtaining the number of subscriptions of the type.

 When the number of available resources of the type is greater than the number of subscriptions of the type, it is determined that the resource of the type has opened the standby resource.

 Determining that the NSRRHP is to release an alternate resource of the type such that the number of available resources of the type is a subscription value of the type

 Specifically, the data information of the current NS performance is too low, indicating that the VNF resource required by the VNF is only 10 MHz, and the VNF resource currently available to the client is 130 MHz, and the VNF subscription value is 30 MHz. VNFM knows through NSAI that the customer's VNF backup resource is 100MHz.

 The VNFM formulates an alternate resource processing policy, and determines to release the VNF backup resource for the V F, so that the VNF

The signing value of the VNF itself can meet the current needs to avoid waste of resources.

 Step S414: The VNFM sends the NSRRHP message to the VIM, and proceeds to step S415b. The NSRRHP message includes policy information for releasing the FVI backup resource.

 Step S415a: The VNFM performs a release operation on the VNF resource.

 Step S415b: After receiving the NSRRHP message, the VIM performs release of the FVI resource according to the policy in the NSRRHP message.

 Through the above method, when the customer's subscription value can meet the running requirement, the standby resource occupied by the customer is released, so as to avoid waste of resources.

 Further, in the method of the embodiment of the present invention, the VNFM may also initiate a release operation of the standby resource.

Specifically, the VNFM determines whether the currently used backup resource usage time exceeds the usage time of the standby resource according to the usage time limit of the standby resource in the NSAI information received from the Orchestrator. If exceeded, the VNFM actively formulates a reserved resource processing policy. Release this part of the spare resource. The method of Embodiment 5 of the present invention is still applied to the scenario of VNFM decision. The difference between the fifth embodiment and the fourth embodiment is that when the Orchestrator receives the NSD sent by the OSS/BSS, it immediately includes the NSAI included therein. The information is sent to the VNFM, and the process of requesting the NSAI from the VNFM to the Orchestrator is no longer needed.

 Referring to FIG. 5, it is a signaling flowchart of a method for allocating network service resources according to Embodiment 5 of the present invention. As shown in FIG. 5, the method includes the following steps:

 Step S501: The OSS/BSS sends the NSD to the Orchestrator. The NSD includes the NS subscription resource information and the NSAI information. After receiving the NSD, the Orchestrator sends the NSAI information to the VFM.

 Step S502: The EMS obtains the running performance of each VNF in the NS.

 Specifically, the EMS can periodically monitor the running performance of each V F in the NS. Alternatively, the EMS can periodically receive the running performance information reported by each VNF in the NS.

 The operating performance of the V F may include: bandwidth usage, data throughput, latency, and the like.

 Step S503: When the EMS finds a performance abnormality alarm of the VNF, the performance abnormality alarm information of the VNF is reported to the VFM.

 Step S504: After receiving the performance abnormality alarm information of the VNF reported by the EMS, the VNFM determines whether the performance is overloaded according to the performance abnormality data. If yes, the process proceeds to step S505; if not, the performance abnormality alarm is performed according to a normal process. deal with.

 After receiving the performance abnormality alarm information of the VNF, the VNFM analyzes and determines the abnormal alarm to determine whether the abnormality is caused by the NS overload, whether it can be solved by adding the NS resource, and if so, opening the standby resource to the VF. The abnormal alarm is solved by adding NS resources.

 Specifically, when the abnormal alarm information is that the resource usage rate is higher than a preset first threshold, determining that the VNF is a performance overload.

 Step S505: The VNFM according to the NS resource information of the NS, the information of the standby resource indicated by the NSAI, and

If the performance of the VNF is abnormal, the corresponding NSRRHP is formulated, and the process proceeds to step S506.

 In the fourth embodiment of the present invention, the VNFM determines, according to the data information of the NS performance overload of the VNF, which types of resources of the VNF are scarce, resulting in an abnormal alarm. At the same time, the VNFM determines which types of spare resources can be enabled for the V F based on the availability of the alternate resources in the NSAI information received from Orchestrator. Then, the VNFM formulates an alternate resource processing strategy, and makes a decision to open the standby resource of the type that is included in the NSAI information and the V F is in short supply.

 Specifically, the formulating the corresponding NSRRHP according to the subscription resource information of the NS, the information of the standby resource indicated by the NSAI, and the performance abnormal data of the VNF includes:

The VNFM determines the type of resource currently experiencing performance overload based on the performance abnormal data of the VNF. Querying the information of the standby resource indicated by the NSAI, and obtaining the quantity of the backup resource of the type; querying the subscription resource information of the NS, and acquiring the subscription quantity of the type. The NSRRHP is formulated to enable the type of spare resources such that the number of available resources of the type is the number of spare resources of the type plus the number of subscriptions of the type.

 Assume that the current V FM determines that the NS performance overload data indicates that the VNF required for the VNF is 80 MHz, and the VNF subscription value of the customer is only 30 MHz. VNFM knows through NSAI that the customer's VNF backup resource is 100MHz.

 Then, the VNFM formulates an alternate resource processing strategy, and determines to enable the VNF backup resource for the V F, so that the VNF can have a 130 MHz resource to solve the current fault.

 Step S506: The VNFM sends the NSRRHP message to the VIM, and proceeds to step S507b. The NSRRHP message includes policy information for extending the FVI resource.

 Step S507a: The VNFM performs an extended operation on the VNF backup resource, that is, a backup resource for enabling the VNF.

 Step S507b: After receiving the NSRRHP message, the VIM performs an extended operation on the FVI backup resource according to the policy in the NSRRHP message, that is, the FVI standby resource is enabled.

 Through the above method, the customer can not only use the normal use resources specified in the contract, but also use the spare resources specified in the NSAI, thereby eliminating the overload abnormality of the NS, avoiding the abnormal interruption of the service, and satisfying the use requirements of the customer. Improve the usability and continuity of NS.

 In order to avoid the waste of NS resources and the use of resources of other VNFs, the method of the embodiment of the present invention further includes: releasing the standby resources occupied by the VNF after the NS overload abnormality of the VNF is eliminated or the usage time of the standby resource is reached.

 Still referring to FIG. 5, after steps S507a and S507b, the method further includes:

 Step S508: The EMS obtains the running performance of each VNF in the NS.

 Specifically, the EMS can periodically monitor the running performance of each V F in the NS. Alternatively, the EMS can periodically receive the running performance information reported by each VNF in the NS.

 The operating performance of the V F may include: bandwidth usage, data throughput, latency, and the like.

 Step S509: When the EMS finds a performance abnormality alarm of the VNF, the performance abnormality alarm information of the VNF is reported to the VFM.

 Step S510: After receiving the performance abnormality alarm information of a VNF reported by the EMS, the VNFM determines whether the performance is too low. If yes, the process goes to step S511; otherwise, the performance abnormality alarm is processed according to a normal process.

Specifically, after receiving the performance abnormality alarm information of the VF reported by the EMS, the VNFM first determines whether the alarm is too low for the VNF performance, and if yes, further determines whether the VNF is turned on before the standby. Resource; if no, the performance exception alert is processed according to the normal process.

 Specifically, the VFM analyzes the performance abnormality alarm information of the VNF. When the resource usage rate of the VF is lower than a preset second threshold, the alarm may be determined to be an alarm with a low VNF performance.

 If it is further determined whether the standby resource is enabled before the VNF, if it is turned on, it is determined that the standby resource of the NS needs to be released for the V F; if not, the performance abnormality alarm is processed according to a normal procedure.

 Specifically, the VNFM determines whether the standby resource is enabled before the VNF according to the NS performance parameter of the VNF and the parameter information in the NSAI.

 For example, by querying the NS performance parameter of the V F, the VNFM determines that the V F subscription value is only 30 MHz, but the actual available resource value of the VNF is currently 130 MHz. Meanwhile, the NS has a standby VNF resource of 100 MHz. From this it can be determined that the VNF has opened the standby resource.

 Since the current resource usage of the VNF is too low, it can be known that the VNF does not need to continue to occupy the standby resource, and thus the standby resource can be released to avoid resource waste.

 Step S511: The VNFM formulates an alternate resource processing policy according to the data information of the VNF whose NS performance is too low, and the situation of the standby resource in the NSAI information, and proceeds to step S512.

 Based on the data information of the VNF whose NS performance is too low, the VNFM determines which types of resources of the VNF are too low to cause an abnormal alarm. At the same time, the VNFM determines which types of spare resources can be released for the VNF based on the conditions of the alternate resources in the NSAI information. Then, the VNFM formulates an alternate resource processing policy, and makes a decision to release the spare resource of the type that is included in the NSAI information and the usage rate of the VNF is too low.

 Specifically, the data information of the current NS performance is too low, indicating that the VNF resource required by the VNF is only 10 MHz, and the VNF resource currently available to the client is 130 MHz, and the VNF subscription value is 30 MHz. VNFM knows through NSAI that the customer's VNF backup resource is 100MHz.

 Then, the VNFM formulates an alternate resource processing policy, and determines to release the VNF backup resource for the VF, so that the subscription value of the VNF itself can meet the current requirement, thereby avoiding waste of resources.

 Step S512: The VNFM sends the NSRRHP message to the VIM, and proceeds to step S513b. The NSRRHP message includes policy information for releasing the FVI backup resource.

 Step S513a: The VNFM performs a release operation on the VNF resource.

 Step S513b: After receiving the NSRRHP message, the VIM performs release of the FVI resource according to the policy in the NSRRHP message.

Through the above method, when the customer's contract value can meet the running demand, the standby occupied by the customer is released. Use resources to avoid wasting resources.

 Further, in the method of the embodiment of the present invention, the VFM may also initiate a release operation of the standby resource.

 Specifically, the VFM determines whether the currently used backup resource usage time exceeds the usage time of the standby resource according to the usage time limit of the standby resource in the NSAI information received from the Orchestrator. If exceeded, the VNFM actively formulates a reserved resource processing policy. , release this part of the spare resource.
