In S902, NSM＆O sends the first inquiry request message according to extended request message to storage device, this first is looked into Ask the authority that request message is used to inquire about the NSM＆O to storage device and extend the network function to be extended of target NSI.
When extended requests are obtained by sending ending equipment sending method, NSM＆O can also be sent out by memory verification The identity of sending end equipment, and verify the integrality of the spreading parameter in the extended requests, for example, just whether target NSI forms Really, whether the service for network function to be extended and/or function descriptor format are correct etc..In the expansion that sending ending equipment is sent The spreading parameter included in exhibition request is incorrect or network section example format is incorrect, and NSM＆O can be fed back to transmitting terminal Extend failed message.NSM＆O can also check that objective network section example whether there is and the objective network is cut into slices at the same time Example operating condition, or NSM＆O check that the corresponding NSLD of objective network section whether there is and objective network section is current State.
After NSM＆O obtains the extended requests of target NSI, the NSLD of NSM＆O associated objects NSI, and the NSLD is combined, NSM＆O corresponds to the function in target NSI and/or service describing in the VNF and/or PNF of target NSI, and verifies the mesh Whether mark NSI can extend.If target NSI is not present, NSM＆O is not present to transmitting terminal feedback target NSI.If mesh Mark NSI cannot extend, then NSM＆O cannot be extended to sending ending equipment feedback target NSI；If target NSI can extend, Then whether NSM＆O has permission the extension for the network function for carrying out target NSI by memory verification transmitting terminal, if verification is obstructed Cross, NSM＆O can fail to transmitting terminal feedback extensions.When extended requests are triggered by NSM＆O internal mechanisms, then NSM＆O is associated The NSLD of target NSI, and determine that target NSI needs the VNF and/or PNF extended with reference to the NSLD.If target NSI cannot Extension, NSM＆O can be to sending ending equipment feedback network performance deficiencies.
In S903, storage device sends the first authentication response information to NSM＆O.The authentication response information is used to indicate to send out Whether the extended requests that sending end equipment is sent can pass through.
If authentication is by the way that or target NSI is not present, then performs in S904, and NSM＆O loses to transmitting terminal feedback extensions Lose result.
Specifically, when extended requests are sent by transmitting terminal, NSM＆O is determined by the certification to transmitting terminal, authentication verification Whether the transmitting terminal, which has permission, is extended the network function of target NSI, if the extended requests verification that transmitting terminal is sent is not By the way that then NSM＆O fails to transmitting terminal feedback extensions.When extended requests are triggered by NSM＆O internal mechanisms, NSM＆O determines mesh Whether the extended requests of mark NSI can extend, if the network function of target NSI cannot extend, NSM＆O is set to transmitting terminal Standby feedback extensions fail, and insufficient to sending ending equipment feedback network performance.
It is to be understood that if step, which performs, treats S904, the whole flow that extends terminates, this extension failure.
In S905, NSM＆O determines the layout result of the network function to be extended of target NSI according to extended requests.
Specifically, NSM＆O determines to need the VNF and/or PNF extended according to extended requests, for example, NSM＆O can be determined Whether dilatation VNF, newly-increased VNF, extension PNF or newly-increased PNF.So that it is determined that the configuring request of network function to be extended, bag Include the VNF, newly-increased VNF, extension VNF or newly-increased PNF of configuration dilatation.
NSM＆O is according to the information in the associated NSLD of target NSI, it can be determined that network function to be extended is to belong to target The universal network function that NSI is shared with other section examples, or belong to the exclusive network functions of target NSI.
When NSM＆O determines that network function to be extended is target NSI and other universal network functions for sharing of section examples, Then perform step S906；, can be with if NSM＆O is determined when the network function extended is the privately-owned network function of target NSI Step S906 is not performed.
In S906, when NSM＆O determines that target NSI network functions to be extended are the network function that more section examples are shared When, the NSLD of the section example of other networks in addition to target NSI of the network function is shared in NSM＆O associations.It is to be understood that here Other networks section example that network function is shared with target NSI is properly termed as associating NSI.Combine association NSI's in NSM＆O After NSLD, according to association NSI NSLD content determine association NSI whether normal operation.
In S907, when NSM＆O sends resource reservation request according to layout result to EM and/or VIM.
Specifically, when NSM＆O is determined when the network function extended is physical network function according to layout result, NSM＆O Resource reservation request is sent to EM, correspondingly, EM is that physical network function to be extended reserves resource according to resource reservation request. When NSM＆O is determined when the network function extended is virtual network function according to layout result, NSM＆O is pre- to VIM transmissions resource Request is stayed, correspondingly, VIM is that virtual network function to be extended reserves resource according to resource reservation request, for example, calculating money Source, storage resource or Internet resources etc..The EM or the VIM receive reservation requests, according to actual conditions reserving network resources, And feed back reserved result and give the NSM＆O.
In S908, the NSM＆O is according to the resource reservation result of the EM or VIM, however, it is determined that reserved failure, then to transmission End sends a notification message, which is used to represent extension failure；Further, which can also carry extension and lose The reason for losing, i.e. No Assets.
If it is to be understood that going to step S908, the whole flow that extends terminates, spreading result failure.
Alternatively, in S909, if the network function to be extended that target NSI is determined after NSM＆O layouts is real by PNF Existing, then NSM＆O sends configuring request to EM, which is used to be configured for the network function to be extended of target NSI.
In S910, EM starts to perform to realizing network to be extended after the configuring request of NSM＆O transmissions is received The PNF of function is configured.
Specifically, EM treats the network function of extension according to NSM＆O and carries out configuration and can be divided into four kinds of situations.
(1) when NSM＆O determines to realize that the PNF of network function to be extended is target NSI and the PNF that associates NSI and share, and And NSM＆O layouts the result is that when allowing existing PNF for service goal NSI with associating NSI and providing more resources, then EM is according to NSM＆ The configuring request of O allows the PNF to distribute more resources, for service goal NSI with associate NSI.
(2) when NSM＆O determines to realize that the PNF of network function to be extended is target NSI and the PNF that associates NSI and share, and And NSM＆O layouts the result is that newly-increased PNF provides service for target NSI with NSI is associated, then EM is according to the configuring request of NSM＆O The newly-increased PNF is configured, which can include target NSI and associate the parameter of NSI, for example, target NSI and Associate the identification information of NSI, NSI monitoring informations and/or report information etc..Certainly, which can also include target NSI And/or the association operating parameter of NSI, policy information, the network connection of privately-owned network function etc. for associating NSI and/target NSI.
(3) when NSM＆O determines to realize that the PNF of network function to be extended is the exclusive PNF of target NSI, and layout knot Fruit is that then EM allows the PNF to distribute more multiple resource according to the configuring request of NSM＆O, is used for when allowing existing PNF configurations more multiple resource Serviced for target NSI.
(4) when NSM＆O determines to realize that the PNF of network function to be extended is the exclusive PNF of target NSI, and layout knot Fruit is that newly-increased PNF provides service for target NSI, then EM is configured according to NSM＆O configuring requests for the newly-increased PNF, the configuration Content can include the parameter of target NSI, for example, the monitoring information of the identification information of target NSI, target NSI and/or reporting Information etc..Certainly, which can also the operating parameter including target NSI, policy information, target NSI privately-owned network work( Network connection of energy etc..
In S911, after the completion of EM treats that the PNF of extended network function is configured according to NMS＆O to realization, Ke Yixiang NSM＆O sends configuration response message, for indicating that the EM has completed the configuration of the network function to be extended.
If it is to be understood that network function to be extended is realized by PNF, go to step S911 and just completed whole target NSI treats the whole flow process of extended network function, if S923~S925. targets NSI can be performed directly, also there are other realizations The PNF of its network function does not complete to configure, then repeats step S909~S911.
Alternatively, in S912, if network function to be extended target NSI is realized by VNF, NSM＆O is to VNFM Extension notification message is sent, which includes the spreading parameter of VNF to be extended.
Specifically, NSM＆O determines layout as a result, the layout result is to realize virtual network function to be extended, including is expanded Hold target NSI and associate the exclusive VNF of VNF, target NSI that NSI shares, newly-increased share exclusive VNF of VNF or newly-increased etc..NSM&O The extension notification message of transmission, for notifying VNFM to realize extension VNF examples, which includes to be extended Identification information, VNF characterisitic parameters information and other spreading parameters of VNF, for example, increased performance needed for extension VNF, pre- The resource stayed, newly-increased or dilatation virtual machine version etc..
