Technical scheme runs on cloud computing platform based on one kind, SDN+NFV of the fusion SDN controls with carrying the mentality of designing separated new network framework, the new network framework has decoupled the network entity that a variety of functions have been coupled in the EPC network architectures, Fig. 1 is the schematic diagram of SDN+NFV new network frameworks, as shown in Figure 1, the SDN+NFV new networks are by concentration network control unit (Single Network Controller, abbreviation SNC), network address translater（Network Address Translation, abbreviation NAT), distributor (Distributor), entrance (Entry), a series of functional node (Function Nodes, abbreviation FN) composition functional node network (Function Nodes Network, abbreviation FNN) and radio node (Radio Nodes, abbreviation RN) composition, function in EPC networks from PGW to base station is splitted out from original physical equipment, according to function granularity, independently it is deployed in FNN.

The flow chart for the inter-node communication processing method embodiment one that Fig. 2 provides for the present invention, as shown in Fig. 2 the inter-node communication processing method of the present embodiment includes：

S101, route determine that node determines the global virtual identifying of target end node, route determines that node is the central control unit or entrance or functional node in software defined network, target end node is the target end node of the routed path of coffret data, interface message and the network information of the global virtual identifying for indicating target end node.

Specifically, the route of the present embodiment determines that node can be the functional node in SNC or entrance or FNN.

It should be noted that, route in the present embodiment determines that node can include for receiving interface data and determine the source end node of global virtual identifying, the network parameter and the node of routing parameter that the processing node on routed path is determined according to global virtual identifying can also be included being used for, situation about potentially including has：Source The node of end node and the network parameter and routing parameter that handle node for determination is the same node in SDN+NFV new network frameworks, when the node of source end node and network parameter and routing parameter for determining to handle node is the different nodes in SDN+NFV new network frameworks, source end node needs the interface data received and the global virtual identifying determined being sent to for determining the network parameter of processing node and the node of routing parameter.

Because the SDN+NFV new network frameworks of the present invention are by the way of software definition, realize the separation of control and carrying, so when the SDN+NFV new networks framework is to user equipment (User Equipment, abbreviation UE) interface data when being transmitted, it needs to be determined that transmitting the routed path of the interface data, i.e. the interface data transmission process needs the processing node passed through, and the processing node can include the target end node of the intermediate processing nodes and the routed path on the routed path.

Long Term Evolution defined in legacy network, such as 3GPP agreements（Long Term Evolution, abbreviation LTE) source of interface data, purpose, type be diversified, such as issuable data just have following several in handoff procedure：One is the switching between two cells in non-standard X2 mouthfuls of data of cell-of-origin and purpose cell direct communication, the main application scenarios of such data such as same base station, its switch data and signaling pass through it is non-standard X2 mouthfuls（Such as privately owned interface）Communicated, its source processing unit may be cell entity or UE entities, and purpose processing unit may be cell entity or UE entities；Two be that cell-of-origin and purpose cell are communicated by X2 mouthfuls, the main application scenarios of such data are to have the cell switching between the base station of X2 mouthfuls of connections, its data switched and signaling can be communicated by X2 mouthfuls, its source processing unit may be cell entity or UE entities, and purpose processing unit may be cell entity or UE entities；Three be that cell-of-origin and purpose cell are communicated by S1 mouthfuls, the main application scenarios of such data are the cell switching between the base station without X2 mouthfuls of connections, its data switched and signaling can be communicated by S1 mouthfuls, its source processing unit may be cell entity or UE entities, and purpose processing unit may be cell entity or UE entities；Four be that cell-of-origin and purpose cell are communicated by mouths such as S1/S10, the main application scenarios of such data are the cell switching between the base station without X2 mouthfuls of connections, its data switched and signaling can be communicated by interfaces such as S1/S10, its source processing unit may be cell entity or UE entities, purpose processing unit may be cell entity or UE entities, and in handoff procedure, it may relate to the conversion of agreement, for example handover request message in need may change into S10 by S1, then change into by S10 S1 process.

By taking simple handoff procedure as an example, its access net side Radio Resource Control entity being related to has：Positioned at the Interface Controller entity of base station side, for directly handling X2 interface message；Positioned at the cell of base station side Controlled entity, for handling the distribution of UE entities and establishment etc.；Positioned at the UE controlled entities of base station side, controlled for UE contexts in handoff procedure；Positioned at the carrying controlled entity of base station side, for the carrying control in handoff procedure.

In the related network elements of core net, due to communication peer-entities the need for, be also required to create or be related to the corresponding controlled entity of correlation in the process, in addition in core-network side, may also need to based on position area, such as Location Area Code（Location area code, abbreviation LAC) or Tracking Area Code (Tracking Area Code, abbreviation TAC) management and controlled entity.

In user surface side, for the data flow based on carrying, but its data flow may be different from conventional up-downgoing data flow, it is necessary to keep the synchronized update routeing in handoff procedure, and such as data flow passes through X2 mouthfuls of transfer（Purpose base station is relayed to by source base station）, or pass through S1 mouthfuls of transfer（By source base station purpose base station is relayed to through core net）.

In the various interface communications of legacy network, it is substantially by application protocol identification（Application Protocol Identifier, abbreviation AP ID and tunnel end mark（Tunnel Endpoint ID, abbreviation TE ID) the AP ID are used primarily in the chain of command of wireless network layer, wherein GTP-U TEID are used primarily in transmission network layer user surface, GTP-C TEID are used primarily in transport network layer chain of command, due to not alignd and uniformly, so often same process, such as S1AP ID and GTP-C TEID in handoff procedure needs to set up mapping relations, so as to in SDN+NFV new network frameworks, there are the following problems：One is in tunnel for former base（Tunnel) how each interface ID that mode communicates, handled in SDN, how with each network node, such as FNN network address is mapped and matched, it is necessary to rethink；Two be the route test for each interface message, it is originally the mode based on Tunnel, the tissue in the form of various interface ID (such as local TE ID), and the transfer and processing of data and signaling are carried out, related route how is carried out under SDN and processing needs are rethought.

In SDN+NFV new network frameworks, control centralization processing, controlling the signaling and process of correlation can consider is carried out inside centralized control node, only need to consider being adapted to for a small amount of SNC and external control interface, and primary concern is that the processing of user plane related data flow, so, the present invention uses a kind of unified global virtual identifying, to replace the interface identifier in legacy network, so as to which SNC can pass through the global virtual identifying, determine the address of the routing node of interface data, and complete the determination of route, and for RN nodes, what it is due to its deployment is probably traditional base station, so, there may be complete or partial radio protocol stack Access Layer inside RN, such as 3G base station, or LTE eNodeB.So as to for the interface data that such source node or destination node are RN, it is determined that road By when, it is believed that its source node or destination node are the interface adapter nodes in FNN, and the mapping and completion that complete internal route and external interface by the interface adapter nodes are handled.

The management in a network of global virtual identifying, transmission and using can be used as an entirety to carry out, can also be that overall segmentation is carried out with certain rule, to become the combination of field, and carried out in units of field, complete global virtual resource mark is unique in network, i.e. synchronization, same global virtual resource mark correspondence two sets or more than two sets heterogeneous networks parameters (such as IP address, port are not had）, there will not be two or more global virtual resource mark correspondence same set of network parameter (such as IP address, port）Situation.

The flow chart for the inter-node communication processing method embodiment three that Fig. 4 provides for the present invention, as shown in figure 4, the inter-node communication processing method of the present embodiment includes：

S301, route determine node distribution and manage the information that global resource is identified in global virtual identifying.Specifically, carry out the planning and deployment of wireless network, carry out planning and deployment that related resource handles node, carry out setting and the adaptation of related resource processing node, carry out the foundation and activation of related resource processing node and resource entity, carry out foundation of connection relation between nodes etc., the distribution of global resource mark is allocated when global resource is set up, and within the management and control for concentrating network control unit, the distribution of global resource mark is direct or indirect by concentration network control unit（For example authorize other nodes）Carry out, and the information for concentrating network control unit to result in and/or set the global resource to identify.

In one embodiment, the information of global resource mark includes：The corresponding processing nodal information of global resource mark, global resource identify corresponding network parameter, global resource and identify at least one of corresponding routing parameter, logical relation of global resource mark.

Nodal information is handled, including：At least one of the tenability for handling node, the disposal ability for handling node, the running status for handling node, connection status of processing node；

The logical relation of global resource mark identifies the inclusion relation between subordinate's global resource mark that attaching relation or global resource mark and global resource between higher level's global resource mark of global resource mark are identified including global resource.

S301 basis is deployment and foundation based on global resource processing unit in SDN+NFV new network frameworks, and due to the concentration of control, control of the chain of command to Radio Resource and the control to transmission are all deployed in SNC, so for global resource（Consideration such as operator, the consideration of cell）The deployment of processing unit, mainly considers RN deployment, and planning and configuration to functional node, for example, plan which functional node is used for the related network elements function of handling some operator（Such as data routing node, RNC/ base stations L2 nodes, base station L1 nodes）, to complete the whole net function of complete wireless communication.

Fig. 5 is a kind of wireless network deployment schematic diagram in SDN+NFV new network frameworks, such as Fig. 5 institutes Show, the resource pool that processing node is only identified in three wireless networks, respectively wireless network 1, wireless network 2 and wireless network 3, FNN, the path with actual deployment have been deployed in Fig. 5（Such as R1 might not correspond to uppermost first Entry) and level（Such as first box of FNN the first rows and second frame may have no direct relation）And it is irrelevant, wherein R represents route processing node, and F represents function treatment node（Such as video compress）, P represents the processing node of radio protocol stack, and I represents the node of interface adaptation, and its routing nodes and functional node can be deployed as the shared network node of multiple wireless networks, and the adjustment of appropriateness can be carried out according to specific connection and service conditions（Such as load balancing）, wherein all kinds of nodes are only logical node, in actual physics deployment, deployment can be combined, Fig. 5 describes convenient for embodiment, is described in the way of separated deployment.

Because RN disposes base station/access point of various forms（Access Point, abbreviation AP), FNN handles various functions and completion and various RN (base station/AP) adaptation as node resource pond, and for the RN without wireless heterogeneous networks, the control section of Radio Resource, can be deployed in SNC either FNN, so, for the control of Radio Resource, it is believed that exist in each SNC, FNN and RN.In addition, network access server（Network Access Server, abbreviation NAS) and the control section of the above concentrate on SNC, and the bottom of radio protocol stack such as L1/L2 is deployed in FNN either RN.

Each network and the explanation of deployment to more than：

For wireless network 1, it requires higher due to reasons such as cell abilities to protocol stack process resource, and relatively few to middle function treatment.So, its node and path planning are, its data flow is needed by two routing nodes R1 and R2, and by function treatment node F1, reach P1 processing nodes, P1 processing nodes are processing radio protocol stack L2 correlation functions, and P2 processing nodes are processing radio protocol stack wireless heterogeneous networks correlation function, P3 is processing radio protocol stack L1 correlation functions, most it is attached afterwards through interface adapter nodes II and RN1, interface adapter nodes for example can be common public radio interface (The Common Public Radio Interface, abbreviation CPRI).

For wireless network 2, due to its wireless related processing be not required for it is very high, but higher is required to middle processing function, so, its node and path planning are that its data flow is needed by a routing node R1, and by function treatment node F1 and F2, P1 processing nodes are reached, P1 processing nodes are processing radio protocol stack L2 and L1 correlation function, are most adapted to afterwards through interface（Such as CPRI) node II and RN2 is attached.The network wireless protocol stack wireless heterogeneous networks correlation function is deployed in SNC.

For wireless network 3, because its network is without intermediate function processing, and for the LTE of inheriting tradition Base-station node eNodeB, so its network need to be only adapted to via routing node R1 and interface（Such as S1 mouthfuls）Node reaches RN3.

Each wireless network for more than, resource tank node may have point of static node, semi-static node and dynamic node, wherein, static node such as RN nodes and interface adapter nodes, its various base station/AP disposed, and corresponding interface adaptation when the network planning, it is necessary to be determined；Semi-static node, such as radio protocol stack relevant treatment node, its each protocol layer disposed handle node and are not required for determining completely when planning, and can be in radio resource entity（Such as cell）Determined when foundation.But such node is general after radio resource entity is created and is run, and before delete next time, its resource is determined substantially, does not take into account that overall migration and change；Dynamic node, such as function treatment node and routing node, because the processing unit on such node is all data flow, so, substantially completely dynamic and shared, i.e., same place（Such as dining room）, use same access network（Such as China Mobile network）, carry out same business（The program request of such as same video）, it is route and the node of function treatment is probably different, and during the progress of business, due to reasons such as node loads, routing node and function treatment node may be migrated and changed.So, for such dynamic node, only need to probably consider that it is connective when planning（I.e. can data flow from NAT to RN) and disposal ability (the general resource consumption of such as function treatment）, so without very careful node planning and determining.

S302, route determine the corresponding relation for the processing node that node is set up in global virtual identifying and software defined network.

The foundation of global resource processing unit mainly includes the foundation of resource entities at different levels, the foundation of such as cell, the foundation of UE contexts, the foundation of business contexts/Business Stream etc..Meanwhile, SNC needs to complete the centralized Control to each processing node.I.e. for docking port communications, global resource processing node its global resource processing mark is at least completed, right resource processing mark for example can be global cell ID, can be Cell Global Identification（Cell Global Identifier, abbreviation CGI)；Global UE marks, can be the UE Context identifier that CGI is distributed plus cell processing unit to the UE, but should be noted, due to being relevant with resource processing entities, so, need to embody its hierarchical relationship, i.e. PLMN/eNB/ cells etc. and uniqueness herein）With the mapping relations of its node network address.

Because the foundation of each global resource needs to get through the communication of each layer simultaneously, so the process can carry out the foundation of longitudinal interface simultaneously.In the foundation of longitudinal interface, mainly get through from core net node to access network node and to UE interface, such as when cell is set up, get through from SNC, to FNN (interface adaptation, function and route processing, optional protocol layer processing etc.）, to the RN (base stations of various forms / AP is disposed）, and (specific end-to-end each layer interface is set up, such as rrc layer, NAS layers of signaling to UE）.

For longitudinal interface, it is defined as the communication interface between non-network peer-entities or processing unit, such as SI interfaces between MME and eNB, IUB interfaces between RNC and NodeB, either interface between rlc layer processing entities and PDCP layer processing entities, or base station processing unit interface and the interface of cell processing unit；Corresponding is horizontal interface, it is defined as the lur interfaces between the S10 interfaces between the communication interface between network peer-entities or processing unit, such as MME, RNC, X2 interface between eNodeB, or the interface in CoMP between scheduling processing unit.

The foundation of longitudinal interface is the succession relation for configuring and setting up resources at different levels and the superior and the subordinate's node.Fig. 6 is that longitudinal interface sets up schematic diagram in SDN+NFV new network frameworks, as shown in Figure 6, network is activated and connected with line interface is deployed according to advance planning by the step of foundation of longitudinal interface is done, in figure 6, respectively in FNN1-P1, there is the bifurcated of longitudinal interface at tri- nodes of FNN2-F2 and FNN3-I1, mainly consider the separation of chain of command interface and interface in the user plane, simultaneously, for network node as similar RN3, the corresponding interface adapter nodes of its FNN can be separated, the node for not limiting interface adaptation is only one, in addition, in NAT, distributor, in Entry and FNN interface mappings, because it has dynamic, so not actual embodiment, Entry and R1 interface is only signal, by the foundation and the foundation of longitudinal interface of global resource processing unit, the network should be able to carry out the access of user and all kinds of basic services.

Horizontal interface is mainly the communication between the Internet resources processing node of processing equity, such as between base station, between cell.

On horizontal interface, due to control centralization, so the relevant control face resource entity being deployed on SNC（Such as NAS) between communication interface（Such as S10 interfaces in former LTE network）It is changed to internal interface, and the network interface between other network elements between node is due to need not be as the horizontal interface of legacy network（Such as X2 interface）IP Tunnel are equally set up, so, during actual horizontal interface is set up, it is only necessary to which the corresponding interface got through in interface adaptation module part between RN is adapted to（Such as X2 mouthfuls of corresponding IP Tunnel).
