Specifically, NSM＆O receives the objective network section example termination request of Sender transmissions or objective network section is deleted Except after request, it is necessary to Repository interacting into row information, pass through the identity of the Repository certifications Sender, verification (such as whether objective network section instance identification form is correct, and objective network section is corresponding for the integrality of parameter in the request Whether NSLD mark forms are correct etc.), whether authentication Sender has permission objective network section example or the deletion of termination request Objective network is cut into slices.NSM＆O checks that objective network section example whether there is and objective network section example is transported at the same time Market condition, or NSM＆O check the state that the corresponding NSLD of objective network section whether there is and objective network section is current.

When in step 1101, the request of Sender transmissions is termination objective network section example, then performs following steps：

If verification authentication is not by performing step 1102 ', NSM＆O feeds back corresponding mistake to Sender, such as informs Sender haves no right termination section example, can not verify Sender identity；

If the authentication is passed and objective network section example exists for verification, step 1103 is performed；

If the authentication is passed but network section example is not present for verification, step 1102 is performed ', i.e., NSM＆O is anti-to Sender Feedforward parameter mistake, informs that the above-mentioned objective network section examples of Sender are not present.

Alternatively, when in step 1101, the request of Sender transmissions is that delete target network is cut into slices, then performs following steps：

If verification authentication is not by performing step 1102 ', NSM＆O feeds back corresponding mistake to Sender, such as informs Sender haves no right to delete network section, can not verify Sender identity；

If the authentication is passed and the corresponding NSLD of objective network section exists, all realities of delete target network section for verification After example, NSM＆O performs step 1112, the corresponding NSLD of delete target network section again；

If objective network is cut into slices, corresponding NSLD is not present, and NSM＆O informs Sender mesh to Sender feedback parameter mistakes Mark network section is not present.

It is to be understood that step 1101 to 1102 or step 1102 ' for NSM＆O verification initiate it is described management request message transmission Hold whether Sender has the specific interaction flow of authority for management of cutting into slices to the network of objective network section.

Step 1103, NSM＆O controls EM and NFVO progress Configuration networks function, deletion related to objective network section example Configuration and network connection, specifically include：

NSM＆O checks that the objective network that need to be terminated section example (referred to as target NSI) and other networks section example are It is no to there is shared universal network function, including shared VNF and shared PNF；And the target NSI that NSM＆O detection needs terminate With the presence or absence of exclusive network function.

(1) when target NSI includes shared PNF, NSM＆O is initiated by Itf-N interfaces to the EM for managing the shared PNF The request of the network function is configured, this is shared PNF and is arranged to clothes of the termination to target NSI by the EM of the instruction management shared PNF Business, the request include but not limited to：Indicate that EM stops the service that shared PNF provides target NSI, delete and be used to support target The configuration parameter of NSI services such as network section instance identification, deletes the strategy of service goal NSI, termination/deletion PNF and target Network connection between NSI privately-owned network functions etc..

Further, the EM for managing the shared PNF performs the request and execution result back.

Further, above-mentioned configuration step is repeated until the service that all shared PNF terminate to target NSI in target NSI.

It is to be understood that (1) manages the NE Explorer EM of the first PNF by described for NSM＆O instructions in step 1103 One PNF is configured to the specific interaction flow of service of the termination to objective network section example.At this time, the first PNF is shared PNF.

(2) when target NSI includes shared VNF, NSM＆O is initiated by Itf-N interfaces to the EM for managing the shared VNF The request of the network function is configured, this is shared VNF and is arranged to clothes of the termination to target NSI by the EM of the instruction management shared VNF Business, the request include but not limited to：Indicate that EM stops the service that shared VNF provides target NSI, delete and be used to support target The configuration parameter of NSI services such as network section instance identification, deletes the strategy of service goal NSI.

Further, NSM＆O indicates NFVO by the shared VNF of Os-Ma-nfvo interface notifications NFVO termination targets NSI In the case where not influencing the service of other networks section example, the resource of shared VNF is shunk.

Further, repeat the above steps until all shared VNF are both configured to termination to target NSI in target NSI Service.

Further, in step 1103, NSM＆O detections need the target NSI to terminate to whether there is exclusive network work( Energy.

(3) when target NSI includes exclusive PNF, NSM＆O initiates to match somebody with somebody by Itf-N interfaces to the EM for managing the exclusive PNF The request of the network function is put, instruction manages the service that the exclusive PNF is arranged to terminate to target NSI by the EM of the exclusive PNF, The request includes but not limited to：Indicate that EM stops the service that exclusive PNF provides target NSI, delete and be used to support target NSI to take The configuration parameter of business such as network section instance identification, deletes the strategy of service goal NSI, termination/deletion PNF and target NSI are special Belong to network connection between network function etc..

Further, the EM for managing the exclusive PNF performs the request and execution result back.If the EM is built in PNF, NSM＆O closes/nullifies the virtual port of PNF；Otherwise EM closes/nullifies the virtual port of PNF.

It is to be understood that (3) manage the NE Explorer EM of the first PNF by described for NSM＆O instructions in step 1103 One PNF is configured to the specific interaction flow of service of the termination to objective network section example.The first PNF is exclusive PNF at this time.

Further, repeat the above steps until all exclusive PNF are both configured to termination to target NSI in target NSI Service.

(4) when target NSI includes exclusive VNF, NSM＆O initiates to match somebody with somebody by Itf-N interfaces to the EM for managing the exclusive VNF The request of the network function is put, instruction manages the service that the exclusive VNF is arranged to terminate to target NSI by the EM of the exclusive VNF, Terminate management of the EM to the exclusive VNF at the same time, that is, the step 1104 in the flow shown in Figure 11, and terminate exclusive VNF management Request, the request include but not limited to：Instruction stops monitoring the VNF operating statuses, and the management function to terminate to the VNF, is deleted Manage object.

If the shared VNF of target NSI, exclusive VNF, shared PNF and exclusive PNF have been terminated, network section is real Example has terminated, and performs step 1114.

It is to be understood that above-mentioned termination shares the mistake that PNF, exclusive PNF, shared VNF and exclusive VNF service objective network section Journey does not have the requirement of sequencing, and the present invention is not construed as limiting.

Step 1105, the management object to VNF is deleted, that is, manages NSM＆O in the EM execution steps 1104 of exclusive VNF On the request to VNF management that terminates.

Step 1106, feed back VNF management object terminations to complete, that is, manage the EM of above-mentioned exclusive VNF and connect by Itf-N Mouth feeds back termination management to NSM＆O and completes confirmation.

Step 1107, NSM＆O closes the virtual of the exclusive VNF by the EM of the above-mentioned exclusive VNF of Itf-N interface notifications management Port, stops the service to target NSI.

Step 1108, NSM＆O passes through the exclusive VNF of Os-Ma-nfvo interface notifications NFVO termination targets NSI and deletion and mesh Mark the connection of NSI privately-owned networks.

Step 1109, NFVO performs cut into slices exclusive VNF termination flows and privately-owned network connection deletion flow.

Step 1110, feed back VNF terminations to complete, that is, NFVO is fed back by Os-Ma-nfvo interfaces to NSM＆O Complete the termination and deletion flow to above-mentioned exclusive VNF.

It is to be understood that step 1104 manages the EM of the exclusive VNF by the exclusive VNF to step 1110 for NSM＆O instructions It is configured to the specific interaction flow of service of the termination to objective network section example.

Step 1111, renewal section example memory, specifically, if also existed in the privately-owned network function of target NSI Other functions of being realized by exclusive VNF are not terminated, repeat step 1104~1110, if the corresponding whole VNF of target NSI and PNF has been terminated, then target NSI has been terminated, and NSM＆O, that is, delete target NSI is in Repository section examples Information in memory.If what Sender was sent in step 1101 is network section example termination request, step 1114 is performed, Otherwise step 1112 is performed.

Alternatively, step 1112, NSM＆O checks that the network that the NSLD to be cut into slices by objective network to be deleted is instantiated is cut into slices The state of example.If there is the network section example not being terminated in objective network section, repeat to walk for this section example Rapid 1103-1111, if there is no the network section example generated according to the NSLD, NSM＆O, which is checked, corresponds to network section Whether NSLD is currently being used.If NSLD is being used, feedback network section deletion error.If NSLD is not by use, hold Row step 1113.

Alternatively, step 1113, the NSLD that NSM＆O cuts into slices current goal network is deleted in Repository.

It is to be understood that step 1112 and step 1113 only just need to perform when Sender sends network section removal request.

Step 1114, Sender networks section example termination/network section is notified to delete and complete.

Therefore, control physical network function management equipment of the embodiment of the present invention and virtual network function management equipment, are supported Cut into slices and manage to network, support the direct layout management of physics network function, NFV MANO are then used for virtual network function System administration layout, supports this system architecture lower network section example termination and network section to delete.In the embodiment of the present invention, energy The network section example third party tenant of operator or acquirement mandate is enough allowed to find to maintain existing example cost of cutting into slices to be higher than it The request termination network section example during income that service band comes, while allow operator to decide not to support current type network During section, such as network section edition upgrading, network section is deleted in request.

Step 1302, certification, authentication, verification and inspection objective network section (or objective network section example).

When in step 1301, the request of Sender transmissions is termination objective network section example, then performs following steps：

If verification authentication is not by performing step 1302 ', NSM＆O feeds back corresponding mistake to Sender, such as informs Sender haves no right termination section example, can not verify Sender identity；

Alternatively, when in step 1301, the request of Sender transmissions is that delete target network is cut into slices, then performs following steps：

If verification authentication is not by performing step 1302 ', NSM＆O feeds back corresponding mistake to Sender, such as informs Sender haves no right to delete network section, can not verify Sender identity；

If the authentication is passed and the corresponding NSLD of objective network section exists, all realities of delete target network section for verification After example, NSM＆O performs step 1315, the corresponding NSLD of delete target network section again；

It is to be understood that step 1301 to 1302 or step 1302 ' for NSM＆O verification initiate it is described management request message transmission Hold whether Sender has the specific interaction flow of authority for management of cutting into slices to the network of objective network section.

Step 1303, NSM＆O checks that the objective network that need to be terminated section example (referred to as target NSI) and other networks are cut Piece example is with the presence or absence of shared universal network function, including shared VNF and shared PNF；And NSM＆O detections need what is terminated Target NSI whether there is exclusive network function.

Further, above-mentioned configuration step is repeated until all shared PNF are both configured to termination to target in target NSI The service of NSI.

It is to be understood that (1) manages the NE Explorer EM of the first PNF by described for NSM＆O instructions in step 1303 One PNF is configured to the specific interaction flow of service of the termination to objective network section example.At this time, the first PNF is shared PNF.

Further, NSM＆O is terminated/closed by NG2 interface notifications VIM, and this shares VNF and target NSI privately-owned network work( Network connection that may be present between energy, discharges respective network resource.VIM performs the request and is fed back by NG2 interfaces and performed As a result.

Further, in step 1303, NSM＆O detections need the target NSI to terminate to whether there is exclusive network work( Energy.

It is to be understood that (2) match somebody with somebody the shared VNF for the EM of the NSM＆O instruction instruction management shared VNF in step 1303 It is set to the specific interaction flow of service of the termination to objective network section example.

(3) when target NSI includes exclusive PNF, NSM＆O initiates to match somebody with somebody by Itf-N interfaces to the EM for managing the exclusive PNF The request of the network function is put, instruction manages the service that the exclusive PNF is arranged to terminate to target NSI by the EM of the exclusive PNF, The request includes but not limited to：Indicate that EM stops the service that shared PNF provides target NSI, delete and be used to support target NSI to take The configuration parameter of business such as network section instance identification, deletes the strategy of service goal NSI, termination/deletion PNF and target NSI are special Belong to network connection between network function etc..

It is to be understood that (3) manage the NE Explorer EM of the first PNF by described for NSM＆O instructions in step 1303 One PNF is configured to the specific interaction flow of service of the termination to objective network section example.The first PNF is exclusive PNF at this time.

(4) when target NSI includes exclusive VNF, NSM＆O initiates to match somebody with somebody by Itf-N interfaces to the EM for managing the exclusive VNF The request of the network function is put, which is arranged to service of the termination to target NSI by the EM of the instruction management shared VNF, EM is configured to the management to exclusive VNF of terminating at the same time, that is, the step 1304 in the flow shown in Figure 13, the request include But it is not limited to：Instruction stops monitoring the VNF operating statuses, and the management function to terminate to the VNF, deletes management object.

Step 1305, the EM for managing exclusive VNF performs the request that NSM＆O manages VNF on termination in step 1104.

Step 1306, the EM for managing above-mentioned exclusive VNF completes to confirm by Itf-N interfaces to NSM＆O feedback termination management.

Step 1307, NSM＆O closes the virtual of the exclusive VNF by the EM of the above-mentioned exclusive VNF of Itf-N interface notifications management Port, stops the service to target NSI.

Step 1308, NSM＆O initiates the exclusive VNF requests that terminate by NG1 interfaces to VNFM, which includes termination to mesh The service that mark NSI is currently running, and close above-mentioned exclusive VNF.

Step 1309, VNFM performs the service that NSM＆O is currently running exclusive VNF on termination in step 1308, VNFM VNF is closed jointly with VNF internal mechanisms.
