Enter；
In the dataplane, S3. it is that user carries out various sex service according to the request content of user equipment, type.
In embodiments herein, the instantiation of control plane is virtual customized network technology in wireless access network of realizing
Premise and important guarantee, the present invention control by levels framework global controller in, resource management（RM）Module will
Resource allocation is carried out to local controller and boarder controller, determine the instantiation position of local controller and boarder controller with
Instantiate module.Before instantiation local controller and boarder controller, resource management（RM）Module is needed by topology pipe
Reason（TM）Module knows the abstracted information of bottom-layer network；Each Topology Management（TM）Resume module configuration, monitor it is single
Region and single mobile communication technology.In the environment of multiple domain or many mobile communication technologies, resource management（RM）Module is needed
Will be by API from the Topology Managements of other networks（TM）Resource is asked in module；TM-M（Topography module is managed）Unit is controlled
By cloud management platform（CMP）The cloud computing module resource of offer；TM-L（Topological link management）Unit is then controlled by SDN controls
The virtual link that platform is maintained.TM modules need to notice the state of the resources such as each functional module and link to RM modules, so
RM modules are facilitated to run mapping algorithm to find suitable mapping solution in bottom physics for virtual controlling network.Instantiation control
We need to consider the influence of two aspects during plane：One is needing to meet network engineering need during map controller functional module
Ask（Such as：Network planning demand, power consumption limitation, operating loss limitation, the limitation of UE geographical position etc.）Needed with service performance
Ask；Next to that configuration maps virtual link needs to meet the time delay of controller function module interconnection and the demand of bandwidth.
Specifically, the specific steps of control plane are instantiated, as shown in figure 4, Topology Management（TM）Module supervision, renewal bottom
Layer physical network is simultaneously regularly to resource management（RM）Module notices bottom physical network resource information.In Step1, a network
Engineering request will trigger the mapping algorithm of control plane（Step2）.Network engineering request can be directed to a special industry
The scene of business（Mobile subscriber business, MTC service etc.）, the scene of a specific demand can also be directed to（UE region
Manage the demands such as position, time delay, bandwidth, specific function）And one produced builds the request of control network.In resource management module
In, the mapping algorithm of control plane（Step2）The virtual functions module of virtual controlling network, virtual link will respectively be produced
Module mapping solution and link maps solution.Mapped and solved according to module, in Step3.a-Step5.a, the Top Modules of global controller
Block is managed（TM-M）Unit is communicated by API with cloud management platform, and the cloud infrastructure to bottom physical network is matched somebody with somebody
Put and resource updates.According to link maps solution, in Step3.b-Step5.b, the link module management of global controller（TM-
L）Module is communicated by API with SDP control platforms, and the SDP infrastructure to bottom physical network is configured and resource
Update.
In the dataplane, initialization UE access procedure is exactly to verify UE identity, authorize and provided for follow-up service
Necessary network element.In UE access procedure, it would be desirable to virtual gateway is disposed to ensure service quality.In service
In request process, virtual gateway carries out the fine or not QOE that will directly influence UE of deployment mechanisms, such as the mobile handoff frequency of UE
Size, degree of the congestion of network of rate, UE data aggregates ability and coding compressed capability etc.；So virtual in UE access
Gateway deployment mechanism link will be an important research point.It is similar with traditional mobile communications network, each user equipment
（UE）It is required for authorizing the sequence of operations such as authentication by local controller and boarder controller during access network.
Under the control by levels network architecture, UE initialization access procedure is as shown in figure 5, specific UE access procedure is by boundary Control
Device is managed.
In Figure 5, in order to be able to smoothly correctly perform gateway deployment strategy by the SDT functional modules in boarder controller,
Global controller needs to supervise by the TM-M modules in Topology Management module and TM-L modules, updates bottom physical network and fixed
When to boarder controller SDT modules notice bottom physical network resource information.In Step1, the connection management client in UE
End（CM-Client）UE access requests are sent to the connection management module in boarder controller（CM-Mod）.Certainly, UE accesses please
The wireless access that Seeking Truth passes through UE（UERA）Module is sent, by the wireless access of local controller（LCRA）What module was received, then
By LCRA-Mod（LCRA modules）It is forwarded to the connection management functional module (CM-Mod) of boarder controller.CM-Client is sent
UE access requests need comprising UE identity identification information, access reason（Call, online）, the information such as resource requirement.Access
Request will trigger Step2, UE authentication, renewal UE geographical position, mandate etc. will be related in Step2 necessary
Function, is required if accessing Internet etc., then needs to divide IP address.What the implementation of these functions may be seriously certainly
Influence completes the time needed for this stage.
Complete after Step2, CM-Mod will be to SDT-Mod in Step3（Gateway deployment mechanism module）Send on UE's
The request of virtual gateway deployment examples.In Step4, SDT-Mod is according to the reception from the TM modules of global controller recently
Bottom physical network information run gateway deployment strategy.According to gateway deployment strategy, we can obtain Virtual Service gateway
（v-SGW）, virtual data gateway（v-PGW）Instantiation deployment particular location.According to obtained deployment mechanisms, in Step5
Middle SDT-Mod will send gateway deployment request to cloud management platform.After cloud management platform receives gateway deployment request, it
Gateway will be disposed and instantiated in Step6 and send ACK to SDT-Mod and indicate gateway deployment success.
After the UE of networking determines v-SGW and v-PGW instantiation positions, FM-Mod（Stream management module）It will be created for UE
One forward-path, the forward-path is a default path to handle the business for being directed to UE or being generated by UE.In Step8-
FM-Mod is namely sent a request to by CM-Mod in Step11, the UE is built by FM-Mod combination SDN infrastructure jointly
SGW and one of PGW acquiescence path.According to foregoing description, the specific descriptions of business are generated for UE：
The business generated by UE, packet will be routed to v-SGW instantiation node by access network.In the step
In, if necessary to customizable protocol stack, then need to carry out the mapping of SDP virtual protocols stack.
The packet that business is generated by UE is to need to be transferred to external equipment（Not in FM-Mod range of management）Will
Data are forwarded a packet to by the node location that v-PGW is instantiated by the default path of structure, and then by PGW according to flow table structure
Or routing table looks for the external equipment.
Be transmitted to internal unit by the UE packets for generating business by packet will be forwarded directly to the purpose by SGW
Equipment.
Under this access rules, FM-Mod will play vital effect to the routing rule of network configuration.When
So, Access Control module（AC-Mod）This access rules can be tested, according to bottom physical network topology, the utilization of resources
The information such as rate carry out the specific default path for determining request.In Step10, FM-Mod is suitable according to UE access style feature selectings
Strategy disposes these routing forwardings rule in SDN Infrastructure platforms.For special access scene, such as require low time delay
Service, have the perspective regular path of setting acquiescence forwarding will be to ensureing that the performance of request play important work as this
With.If when delay requirement is not high or undefined under scene, whenever SDN switch parses the first of UE data flows
During individual packet, all by the generation routing forwarding rule of SDN controller irritability, rather than by being created by Step8-Step11
The default path built.
Work as connection management（CM-Mod）Functional module is received after the ACK of data stream configuration, it will triggering wireless access is held
Carry setting up procedure（Step12）.Finally, in Step13, access is sent to UE CM-Client modules by CM-Mod and completed
Information shows that initialization UE access procedures are completed.
In the dataplane, UE, which triggers service request procedure, to ask diversity according to UE request content, type
Service；But the diversity of service needs diversified protocol stack to be ensured.Virtual protocol stack being capable of asking according to UE
Ask to customize multifarious protocol stack, and then to ensure the diversity of service.And the quality of virtual protocol stack mapping mechanism will be straight
Connect size for having influence on the receptance asked in network, network resource utilization, resource loss etc.；So virtual protocol stack maps
Mechanism link is extremely important.
As shown in fig. 6, UE produces service request if desired, triggering service request will be sent in UE App clients,
Then by UE connection management client（CM-Client）To the connection management module of boarder controller（CM-Mod）Send service
Request.Identity information of the service request comprising UE, information of request service etc..The connection management module of boarder controller（CM-
Mod）Establishment RAB will be initialized（Step3）And local controller builds virtual protocol stack mapping mechanism
（Step4）With stream configuration is carried out in SDN infrastructure（Step5-8）；In local controller, wireless traffic carrying is related to
Different radio access modules（RA-Mod）, such as what the wireless traffic carrying of control plane and datum plane was related to wireless connects
It is RAC-Mod and RAD-Mod respectively to enter module.In virtual protocol stack mapping mechanism in Step2, it will by SDP technologies,
Local controller, boarder controller and cloud management platform carry out the deployment mechanisms of Joint Designing virtual protocol stack.Step4,6,7 with just
Beginningization UE access procedures are similar, and unique difference forward-path is related to private radio carrying, and the qos requirement of dedicated bearer can take
Certainly in UE priority level, particular service instance or based on the application program for asking service.When RAB is founded, virtually
After the completion of protocol stack mapping, forward-path, the connection management module of boarder controller（CM-Mod）Service request ACK will be sent
To UE（Step9）；Finally, in Step10, UE App clients can send upstream data and give App servers.
