To by the design so that have the mark of the VNFD or nestedNSD of substitution PNF node in NSD, with Fast transferring is carried out to PNF in subsequent, without redesigning again to PNF.

Above-mentioned PNF moving method is described in detail respectively under different scenes below.

It is a kind of process of physical network function PNF moving method provided in an embodiment of the present invention referring first to Fig. 2, Fig. 2 Schematic diagram, this method are applied to network function and virtualize NFV system, and the NFV system includes network function virtualization composer NFVO.Embodiment shown in Fig. 2 is used in PNF failure, Network Management System (Operations Support System, letter Claim OSS) activly request NFVO carry out PNF migration scene in.

In embodiments of the present invention, when the mark for the VNFD or nestedNSD for devising substitution PNF node in NSD Afterwards, first to NS carry out initial caseization obtain PNFD mark with PNF node instanceization identify, then again to PNFD mark with The function that PNF node instance identifies corresponding PNF node carries out Autonomic Migration Framework and moves back, it can by executing shown in Fig. 2 The step of PNF Autonomic Migration Framework and move back.In step process shown in Fig. 2, step S201- step S203 shows NS The process of initial case, step S204- step S208 show the process of PNF migration, and step S209- step S213 is shown The process that PNF moves back.Details are as follows:

Step S201, OSS sends instantiation instruction message to NFVO.NFVO receives the instantiation instruction message that OSS is sent.

Wherein, the instantiation instruction message, which is used to indicate, identifies corresponding PNF node progress NS example to the PNFD Change, to obtain PNF node instanceization mark for subsequent progress PNF fast transferring.It include PNFD in the instantiation instruction message Mark.

In embodiments of the present invention, when needing newly to establish a network service, OSS sends instantiation to NFVO and refers to Show message, for example, OSS sends instantiation instruction message to NFVO, thus at this time when needing to establish a voice call service NS initial case will be carried out, and corresponding PNF node is identified to PNFD during NS initial case and carries out NS example Change.

Optionally, when PNF failure, under the scene that PNF migration is actively initiated by OSS, which may be used also To include network node deployment mark, it is used to indicate NS network node and carries out PNF deployment or VNF deployment.Specifically, at this time should Instantiate instruction message can for instantiation NS request (InstantiateNsRequest) message, by Increase PNFD mark in InstantiateNsRequest message and PNF or VNF deployment mark, Lai Jinhang NS initialize example Process.To which when being disposed using PNF, NFVO is identified PNF node instance is returned to OSS.

Optionally, which may be other interface message types, for realizing corresponding function.

Optionally, in one embodiment of the invention, which can be In InstantiateNsRequest message, by increasing PNFD mark newly in the InstantiateNsRequest message (PNFD_id) and priority tag (PNForVNF_priority_flag).PNForVNF_priority_flag is for referring to Show that the network node in NS dispose using PNF or VNF is disposed, work as PNForVNF_priority_flag=PNF, Then the network node is disposed using PNF, works as PNForVNF_priority_flag=VNF, then the node is carried out using VNF Deployment.

Specifically, in one embodiment of the invention, the form of message of the instantiation instruction message can be with are as follows: InstantiateNsRequest (NS id, PNFD_id, PNForVNF_priority_flag=PNF), wherein InstantiateNsRequest indicates instantiation NS request, and NS id indicates to need the mark of the NS instantiated, and PNFD_id is used In indicating PNFD mark, PNForVNF_priority_flag=PNF is for indicating that network node is disposed using PNF.

Step S202, NFVO carries out NS initial case process according to instantiation instruction message.

Specifically, in embodiments of the present invention, when the network node is disposed using PNF, then in NS instantiation completion After obtain PNF node instance identification information.

It optionally, can also be by under the 5th third-generation mobile communication technology (5th-Generation, abbreviation 5G) network scenarios Network slice carries out NS initial case.

Step S203, NFVO sends the response message of instantiation instruction message to OSS.

It specifically, include that PNF node instanceization identifies in the response message of the instantiation instruction message, for notifying NFVO The PNF node instantiated on NS.

It is appreciated that by adding PNForVNF_priority_flag in instantiation instruction message, so as to logical Message is crossed to indicate to carry out network node PNF deployment or VNF deployment.

In embodiments of the present invention, after having executed NS initial case process, when PNF failure, step can be used The step of S204- step S208, carries out PNF migration automatically.

It is to be appreciated that above-mentioned NS initial case process also can be applied to non-PNF failure, OSS activly request PNF cloud Migrate scene.

Step S204, in PNF failure, OSS receives PNF failure message.

Specifically, when PNF failure, PNF will by entity management system (Element Manager System, EMS) PNF failure message is reported to OSS system.

Step S205, OSS sends triggering migration message to NFVO.NFVO receives the triggering migration message that OSS is sent.

Wherein, the triggering migration message migrates the function of PNF node to NFV for triggering the NFVO, the touching It includes physical network function descriptors PNFD mark corresponding with the PNF node and PNF node instance that deportation, which moves message, It identifies, there is the virtual network resource description of substitution PNF, the NSD is for identifying PNF node place net in the NSD The network service of network business NS describes, and the network service of network service NS is retouched where the NSD is used to identify the PNF node It states, the virtual network resource is described as virtual network function descriptor VNFD or nested type virtual network business description nestedNSD。

In embodiments of the present invention, due to having completed the design to NSD before the migration of the function of PNF node.In The virtual network resource description for increasing substitution PNF in NSD, so that can realize Autonomic Migration Framework when needing to carry out PNF migration.

Wherein, PNFD is used to identify physical network function description of the function of PNF node on NS.

PNF node instanceization mark is for identifying the PNF node instantiated in NS, to take in triggering migration message It can be used for the PNF node that OSS informing NFVO needs to instantiate with PNDF mark and PNF node instanceization mark.The PNF node Instantiation mark can be one, or multiple.

Optionally, when PNF failure, under the scene that PNF migration is actively initiated by OSS, which be can be When PNF failure, PNF is by EMS, and by fault information reporting to OSS system, the request that then OSS system is sent to NFVO is carried out The message of PNF migration.Namely it can be carried out at this time by carrying PNF migration mark in triggering migration message for triggering NFVO PNF migration.Specifically, the triggering migration message be update NS request message (UpdateNsRequest) message, carry PNF to VNF migrates (PNF_Migrate_to_VNF) mark.

Optionally, which is also possible to when operator needs to carry out the migration of PNF cloud node, by OSS The message that the request PNF sent to NFVO is migrated.Specifically, at this point, the triggering migration message may be UpdateNsRequest message.

Optionally, which may be other newly-increased interface message classes for realizing above-mentioned function Type.For example, PNFMigratetoVNFRequest message.

Specifically, in one embodiment of the invention, the concrete form of the triggering migration message can be with are as follows: UpdateNsRequest (NS id, PNF_Migrate_to_VNF, Be_Migrated_PNFD id, PNF ins id), In, UpdateNsRequest indicates to update NS request, and PNF_Migrate_to_VNF indicates PNF moving to VNF, Be_ The PNFD mark for the PNF that Migrated_PNFD id is used to indicate to migrate, PNF ins id is for indicating PNF node instance Change mark.

Specifically, in another embodiment of the present invention, which may be newly-increased interface message, should The form for triggering migration message can be with are as follows: PNFMigratetoVNFRequest (NS id, Be_Migrated_PNFD id, PNF ins id).Wherein, PNFMigratetoVNFRequest indicates that PNF moves to the request of VNF.

Step S206, NFVO carries out the validity checking of PNF migration.

Specifically, at this time NFVO judge whether to have in NSD template according to the NSD that NS id is indicated the PNFD for substituting the PNF or Person nestedNSD.When NFVO determined according to the NSD that NS id is indicated whether have in NSD template the PNFD for substituting the PNF or When nestedNSD, NFVO determines that the validity checking of PNF migration passes through, therefore executes step S207 and carry out PNF migration.Otherwise, no It executes.

Step S207, the described NFVO triggers the PNF resource distribution in NFV described in the NFV system-kill, and based on described PNFD mark, PNF node instanceization mark and virtual network resource description instantiate the virtual network of the PNF Resource, the virtual network resource be virtual network function VNF corresponding with the VNFD, or with described nestedNSD pairs The built-in network business (nestedNS) answered.

Wherein, virtual network resource refers to for replacing the virtual resource of above-mentioned PNF function in VNF system, to be based on The virtual resource may be implemented to migrate PNF function into VNF system.

Specifically, NFVO instantiates the connection resource and relevant configuration of mark deletion and failure PNF, and example according to PNF Change new VNF or nestedNS.

Step S208, after the completion of PNF instantiation, NFVO sends migration success notification message to OSS.OSS receives NFVO hair The migration success notification message sent.

Optionally, in one embodiment of the invention, the migration success notification message further includes in following information It is at least one:

The mark of the PNFD, the mark of virtual network resource description and the virtual network resource.

Wherein, the mark of virtual network resource description and the mark of virtual network resource are for indicating that PNF function is moved After moving to VNF, occupied NFV resource.

Optionally, if being the NVF instantiated instead of the virtual network resource of the PNF, virtual network resource description Mark can identify (VNFD identification, VNFD ID) for VNFD, which is identified as VNF mark (VNF identification, VNF ID).

Optionally, if being the nested NS instantiated, the virtual network resource instead of the virtual network resource of the PNF The mark of description can identify (nested NS identification, nested NS ID) for nested NSD, this is virtual Internet resources are identified as nested NS mark (nested NS identification, nested NS ID).

It optionally, can also include that PNF migrates success flag in the migration success notification message, for notifying OSS, PNF It migrates successfully.

It is appreciated that being described by the virtual network resource for carrying replacement PNF function in the message that VNFD returns to OSS Mark and virtual network resource mark, so as to so that OSS more directly know replacement PNF function virtualization money Source.
