Specific embodiment

In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is A part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art Every other embodiment obtained without creative efforts, shall fall within the protection scope of the present invention.

Technical solution of the present invention is based on one kind and runs on cloud computing platform, and fusion SDN controls the design isolated with carrying The new network framework of the SDN+NFV of thinking, which, which has decoupled in the EPC network architecture, has coupled multiple functions Network entity, Fig. 1 is the schematic diagram of SDN+NFV new network framework, as shown in Figure 1, the SDN+NFV new network is by concentration net 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 The functional node network (Function Nodes Network, abbreviation FNN) and nothing of (Function Nodes, abbreviation FN) composition Line node (Radio Nodes, abbreviation RN) composition, by the function in EPC network from PGW to base station from original physical equipment It splits out, according to function granularity, is independently deployed in FNN.

Fig. 2 is the flow chart of inter-node communication processing method embodiment one provided by the invention, as shown in Fig. 2, this implementation Example inter-node communication processing method include:

S101, the global virtual identifying for determining that node determines target end node is routed, routes and determines that node is software definition Concentration network control unit or entrance or functional node in network, target end node are the routing of coffret data The target end node in path, global virtual identifying are used to indicate the interface message and the network information of target end node.

Specifically, the routing of the present embodiment determines that node can be the function section in SNC or entrance or FNN Point.

It should be noted that the routing in the present embodiment determines that node may include for receiving interface data and determining complete The source end node of office's virtual identifying, also may include for determining the processing node on routed path according to global virtual identifying The node of network parameter and routing parameter, the case where may include, have: source end node and the network ginseng for determining processing node Several and routing parameter node is the same node in SDN+NFV new network framework, when source end node and for determining processing When the network parameter of node and the node of routing parameter are the different nodes in SDN+NFV new network framework, source end node is needed The interface data received and the global virtual identifying determined are sent to the network parameter for being used to determine processing node and The node of routing parameter.

Since SDN+NFV new network framework of the invention is by the way of software definition, point of the control with carrying is realized From so when interface data of the SDN+NFV new network framework to user equipment (User Equipment, abbreviation UE) carries out When transmission, it is thus necessary to determine that transmit the routed path of the interface data, i.e. the interface data transmission process processing section that needs to pass through Point, the processing node may include the target end node of the intermediate processing nodes and the routed path on the routed path.

Traditional network, such as long term evolution defined in 3GPP agreement (Long Term Evolution, abbreviation LTE) connect The source of mouthful data, purpose, type are diversified, for example, in handoff procedure issuable data just there are several types of: First is that non-standard X2 mouthfuls of data of source cell and purpose cell direct communication, in the main application scenarios of such data such as same base station Switching between two cells, the data and signaling of switching are communicated by non-standard X2 mouthfuls (such as privately owned interface), Source processing unit may be that perhaps UE entity purpose processing unit may be cell entity or UE entity to cell entity；Two It is that source cell and purpose cell are communicated by X2 mouthfuls, the main application scenarios of such data are between having the base station of X2 mouthfuls of connections Cell switching, switching data and signaling can be communicated by X2 mouthful, source processing unit may be cell entity or Person's UE entity, purpose processing unit may be cell entity or UE entity；Third is that source cell and purpose cell by S1 mouthfuls into Row communication, cell switching of the main application scenarios of such data between the base station of no X2 mouthfuls connection, the data and signaling of switching It can be communicated by S1 mouthfuls, source processing unit may be cell entity or UE entity, and purpose processing unit may be Cell entity or UE entity；Fourth is that source cell and purpose cell are communicated by mouths such as S1/S10, such data is mainly answered Cell switching between being the base station connected no X2 mouthfuls with scene, the data and signaling of switching can be carried out by interfaces such as S1/S10 Communication, source processing unit may be that perhaps UE entity purpose processing unit may be cell entity or UE to cell entity Entity, and in handoff procedure, it may relate to the conversion of agreement, such as switching request message in need may be changed by S1 S10, then change by S10 the process of S1.

By taking simple handoff procedure as an example, the access net side Radio Resource Control entity being related to has: being located at base station side Interface Controller entity, for directly processing X2 interface message；Positioned at the cell controlled entity of base station side, for handling UE entity Distribution and creation etc.；Positioned at the UE controlled entity of base station side, for UE context control in handoff procedure；Positioned at holding for base station side Controlled entity is carried, for the carrying control in handoff procedure.

In the related network elements of core net, due to communicate peer-entities needs, be also required in the process creation or It is related to relevant corresponding controlled entity, furthermore in core-network side, may also needs based on position area, such as Location Area Code The management of (location area code, abbreviation LAC) or Tracking Area Code (Tracking Area Code, abbreviation TAC) And controlled entity.

In user surface side, for the data flow based on carrying, but its data flow may be with conventional uplink and downlink data flow Difference needs to keep the synchronized update of routing in handoff procedure, for example, data flow by X2 mouthfuls of transfer (by source base station Go to purpose base station), or pass through S1 mouthfuls of transfer (being relayed to purpose base station through core net by source base station).

In the various interface communications of traditional network, it is substantially through application protocol identification (Application Protocol Identifier, abbreviation AP ID and tunnel end identify (Tunnel Endpoint ID, the abbreviation TE ID) AP ID is used primarily in the control plane of wireless network layer, and wherein GTP-U TEID is used primarily in transmission network layer user surface, GTP-C TEID is used primarily in transport network layer control plane, due to not being aligned and uniformly, so the often same process, such as switch S1AP ID and GTP-C TEID in process needs to establish mapping relations, thus, in SDN+NFV new network framework, There are the following problems: first is that for each interface ID that former base is communicated in tunnel (Tunnel) mode, such as where in SDN network How reason, mapped and be matched with each network node, such as the network address of FNN, need to rethink；Second is that for each The route test of a interface message is originally the mode based on Tunnel, with the shape of various interface ID (such as local TE ID) Formula tissue, and the transfer and processing of data and signaling are carried out, related routing how is carried out under SDN network and processing needs again Consider.

In SDN+NFV new network framework, control centralization processing, controlling relevant signaling and process be can consider all It is to be carried out inside centralized control node, it is only necessary to consider being adapted to for a small amount of SNC and external control interface, and mainly consider It is the processing of user face related data flow, so, the present invention uses a kind of unified global virtual identifying, to replace traditional net Interface identifier in network, so that SNC can determine the address of the routing node of interface data by the overall situation virtual identifying, and The determination of routing is completed, and for RN node, what it is due to its deployment may be traditional base station, so, may have inside RN Complete or partial radio protocol stack access layer, for example, 3G base station or LTE eNodeB.To be saved for such source The interface data that point or destination node are RN, when determining routing, it is believed that its source node or destination node are For the interface adapter nodes in FNN, and the mapping and completion of internal routing and external interface are completed by the interface adapter nodes Reason.

Management, transmission and the use of global virtual identifying in a network can be to be carried out as a whole, is also possible to Whole segmentation is carried out with certain rule, to become the combination of field, and is carried out as unit of field, complete global virtual money Source mark is unique in network, i.e. synchronization, do not have corresponding two sets or two sets of the same global virtual resource mark with It is corresponding same to there will not be two or more global virtual resource marks for upper heterogeneous networks parameter (such as IP address, port) The case where a set of network parameter (such as IP address, port).

In one embodiment, global virtual identifying includes interface type mark and global resource mark；

Interface type mark includes standard interface mark or self defined interface mark.

In one embodiment, global resource mark includes that logical resource identification information, physical resource in network identify At least one of information, dynamic resource identification information, group identification information.

For example, table 1 is a kind of possible global virtual identifying, and as shown in table 1, which includes interface Type identification and global virtual resource mark, wherein global virtual resource mark includes public land mobile network (Public Land Mobile Network, abbreviation PLMN) mark, TAC/LAC mark, Base Station Identification, cell ID, UE mark and hold Carry mark.

Table 1

Specifically, global resource mark can be actual radio resource mark such as cell ID, Base Station Identification, hold Carry mark, be also possible to virtual resource mark for example for the measurement mark of resource status measurement, or for multicast or The group of broadcast identifies.

Global resource mark can be independent global resource mark, be also possible to combined global resource mark, wherein What the independent overall identification was distributed unitedly and was managed within the scope of whole net, in mark can without hierarchical relationship, it includes and It is not limited to lower example, if the global load identification of certain of certain overall situation UE resource identification and the UE is concentrating network control unit, It is same resource identification, and can not be identified according to overall situation UE can intuitively obtain its attaching relation with global load identification； The global resource mark of the combination has multiple identification sections within the scope of whole net, each identification section may have duplicate mark Know, but the mark after combination is unique in the overall situation.It includes and be not limited to lower example: for global cell ID, by PLMN mark and CELL identify two resource section compositions, identify identical two global cell IDs, PLMN for CELL Mark must be different, and the distribution identified in multiple identification section, which can be, carries out unified distribution pipe by concentration network control unit Reason, distributed management can also be carried out according to certain rules, it includes but be not limited to lower example: global cell ID, It identifies two resource sections by PLMN mark and CELL and forms, can be by the concentration network control unit PLMN distribution identified and pipe Reason identifies corresponding processing node by PLMN and carries out the distribution and management that CELL is identified under the PLMN.

In one embodiment, S101 may include:

Route the global virtual identifying for determining that node receives SNC configuration；Alternatively,

It routes and determines that node sends global virtual identifying request message to SNC, and receive SNC transmission includes global empty The response message of quasi- mark；Alternatively,

It routes and determines that node determines global virtual identifying by self study.

Specifically, it is routed in the present embodiment and determines that node can be entrance or functional node, rather than SNC.

S102, determining node is routed according to global virtual identifying, determine the network parameter of the processing node on routed path And routing parameter.

Specifically, if the routed path of the data in network complete by static programming, according to target end node Global virtual identifying can determine the processing node on entire routed path；If the routed path dynamic of the data in network is advised It draws, then needs to determine the target end node on routed path according to the global virtual identifying of target end node first, in conjunction with Network state information, such as the load information of functional node etc. determine the intermediate processing nodes on routed path, above-mentioned processing section Point can be logical node, multiple processing nodes can be deployed on same physical equipment, by relevant network parameter with Resource identification distinguishes.

For example, S102 may include two kinds of situations: first is that source routing mode, that is, route and determine node according to global empty Quasi- mark, determines the network parameter and routing parameter of all processing nodes on routed path, as the SNC for executing node or Functional node in entrance or FNN can determine all processing nodes on routed path according to global virtual identifying Network parameter and routing parameter；Second is that hop-by-hop routes, routes and determine that node according to global virtual identifying, determines Processing Interface data Routed path on the first processing node so that the first processing node determines according to the global virtual identifying that receives and routes road The network parameter and routing parameter of second processing node on diameter, second processing node are the next-hop processing of the first processing node Node, until target end node.

In one embodiment, network parameter includes network address, network identity, port numbers, the protocol class for handling node At least one of type, service type, mass parameter；Routing parameter includes the network address for handling node, network identity, port Number, at least one of protocol type, service type, mass parameter.

Fig. 4 is the flow chart of inter-node communication processing method embodiment three provided by the invention, as shown in figure 4, this implementation Example inter-node communication processing method include:

S301, the information that determining node distributes and manages global resource mark in global virtual identifying is routed.

Specifically, the planning and deployment of wireless network are carried out, the planning and deployment of related resource processing node are carried out, into Row related resource handles the setting and adaptation of node, carries out the foundation and activation of related resource processing node and resource entity, into The distribution of the foundation etc. of row connection relation between nodes, global resource mark is allocated when global resource is established, and in collection Within the control of middle network control unit, the distribution of global resource mark is by the direct or indirect (example of concentration network control unit As authorized other nodes) it carries out, and concentrate network control unit that can obtain and/or be arranged the information that the global resource identifies.

In one embodiment, the information of global resource mark include: global resource identify corresponding processing nodal information, Global resource identifies corresponding network parameter, global resource identifies corresponding routing parameter, the logical relation of global resource mark At least one of.

Handle nodal information, comprising: the tenability for handling node, the processing capacity for handling node, the fortune for handling node At least one of row state, the connection status for handling node；

The logical relation of global resource mark includes higher level's global resource mark of global resource mark with global resource mark Include pass between attaching relation or global resource mark between knowledge and junior's global resource mark of global resource mark System.

The basis of S301 be deployment and foundation based on global resource processing unit in SDN+NFV new network framework, by In the concentration of control, control of the control plane to radio resource and the control to transmission are all deployed in SNC, so for global resource The deployment of (such as the considerations of the considerations of operator, cell etc.) processing unit mainly considers the deployment of RN, and to function section The planning and configuration of point, such as plan which functional node for handling related network elements function (such as data road of some operator By node, the base station RNC/ L2 node, base station L1 node etc.), 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 framework, as shown in figure 5, disposing in Fig. 5 There are three wireless network, respectively wireless network 1, wireless network 2 and wireless network 3, only mark processing node in FNN Resource pool, with the path of actual deployment (such as R1 might not corresponding uppermost first Entry) and level (such as FNN The first box of the first row and second frame may have no direct relation) and it is irrelevant, and wherein R represents route processing node, F generation Table function handles node (such as video compress etc.), and P represents the processing node of radio protocol stack, and I represents the node of interface adaptation, Wherein routing node and functional node can be deployed as the shared network node of multiple wireless networks, and can be according to specifically connecting The adjustment (such as load balancing) that appropriateness is carried out with service conditions is connect, wherein all kinds of nodes are only logical node, in actual object In reason deployment, it can be that embodiment description is convenient in conjunction with deployment, Fig. 5, be described in the way of separated deployment.

Due to base station/access point (Access Point, abbreviation AP) of RN deployment various forms, FNN is as node resource Pond handles various functions and completes the adaptation with various RN (base station/AP), and the RN for being free of wireless heterogeneous networks, wirelessly The control section of resource can be deployed in SNC either FNN, so, the control for radio resource, it is believed that each Exist in SNC, FNN and RN.In addition, network access server (Network Access Server, abbreviation NAS) and with On control section concentrate on SNC, and the bottom of radio protocol stack such as L1/L2 is deployed in FNN either RN.

To the explanation of above each network and deployment:

It is more demanding to protocol stack process resource due to cell ability etc. for wireless network 1, and to centre Function treatment it is relatively few.So node and path planning are, data flow need by two routing node R1 and R2, and pass through function treatment node F1, it reaching P1 and handles node, it is processing radio protocol stack L2 correlation function that P1, which handles node, And P2 processing node is processing radio protocol stack wireless heterogeneous networks correlation function, P3 is processing radio protocol stack L1 correlation function Can, it is most attached afterwards through interface adapter nodes I1 and RN1, interface adapter nodes for example can be common public radio interface (The Common Public Radio Interface, abbreviation CPRI).

For wireless network 2, since its wireless relevant processing is not required for very high, but intermediate processing function is wanted Ask higher, so, node and path planning are that data flow is needed by a routing node R1, and passes through function treatment Node F1 and F2 reach P1 and handle node, and it is processing radio protocol stack L2 and L1 correlation function that P1, which handles node, most afterwards through interface Adaptation (such as CPRI) node I1 and RN2 is attached.The network wireless protocol stack wireless heterogeneous networks correlation function is deployed in SNC。

For wireless network 3, since its network is without intermediate function processing, and it to be used for the LTE base station node of inheriting tradition ENodeB, so its network only need to reach RN3 via routing node R1 and interface adaptation (such as S1 mouthfuls) node.

For above each wireless network, resource tank node may have static node, semi-static node and dynamic node it Point, wherein static node such as RN node and interface adapter nodes, the various base station/AP and corresponding interface of deployment are suitable Match, needs to be determined when the network planning；Semi-static node, such as radio protocol stack relevant treatment node, deployment Each protocol layer processing node be not required for determining completely when planning, and can be (such as small in radio resource entity Area) it determines when establish.But such node is generally after radio resource entity creates and runs, before delete next time, Its resource determines substantially, does not take into account that whole migration and change；Dynamic node, such as function treatment node and routing node, Since the processing unit on such node is all data flow, so, substantially dynamic and shared, i.e., same place completely (such as dining room) carries out the same business (such as the point of same video using same access network (such as China Mobile network) Broadcast), the node of routing and function treatment may be different, and during the progress of business, due to node load etc. Reason, routing node and function treatment node may migrate and change.So for such dynamic node, planning when Time only needs probably to consider its connectivity (i.e. can data flow from NAT to RN) and processing capacity, and (such as function treatment is general Resource consumption), so without very careful node planning and determining.

S302, the corresponding pass for determining that node establishes global virtual identifying with the processing node in software defined network is routed System.

The foundation of global resource processing unit mainly includes the foundation of resource entities at different levels, such as in the foundation of cell, UE Foundation hereafter, the foundation of business contexts/Business Stream etc..Meanwhile SNC needs to complete the concentration control to each processing node System.I.e. for interface communication, global resource processing its global resource of node processing mark, the right Energy Resources Service are at least completed Reason mark for example can be global cell ID, can be Cell Global Identification (Cell Global Identifier, letter Claim CGI)；Global UE mark, can be the UE Context identifier that CGI is distributed plus cell processing unit to the UE, but need It is noted that due to being related with resource processing entities, so, need to embody its hierarchical relationship, i.e. PLMN/eNB/ cell herein Deng and uniqueness) with the mapping relations of its node network address.

Due to the communication of each global resource established while needing to get through each layer, so the process can carry out longitudinal connect simultaneously The foundation of mouth.In the foundation of longitudinal interface, the interface from core net node to access network node and to UE is mainly got through, Such as when cell is established, get through from SNC, to FNN (interface adaptation, function and route processing, optional protocol layer processing Deng), to RN (base station of various forms/AP deployment), and to UE (specific end-to-end each layer interface is established, for example, rrc layer, NAS layers of signaling etc.).

For longitudinal interface, the communication interface being defined as between non-network peer-entities or processing unit, such as MME S1 interface between eNB, IUB interface or rlc layer processing entities and PDCP layers of processing entities between RNC and NodeB Between interface or base station processing unit interface and cell processing unit interface；Corresponding is horizontal interface, It is defined as the communication interface between network peer-entities or processing unit, such as the S10 interface between MME, between RNC Iur interface, the interface in the X2 interface or CoMP between eNodeB between scheduling processing unit.

The foundation of longitudinal interface is the succession relation for configuring and establishing resources at different levels and the superior and the subordinate's node.

Fig. 6 is that longitudinal interface establishes schematic diagram in SDN+NFV new network framework, as shown in fig. 6, longitudinal interface is built Network is activated and is connected to line interface is deployed according to preparatory planning by the step of vertical done, and in Fig. 6, is existed respectively There is the bifurcated of longitudinal interface at tri- nodes of FNN1-P1, FNN2-F2 and FNN3-I1, mainly in view of control plane interface and use The separation of family face interface, meanwhile, for network node as similar RN3, the corresponding interface adapter nodes of FNN can divide It opens, i.e., the node for not limiting interface adaptation is only one, in addition, in the interface mappings of NAT, distributor, Entry and FNN On, since it has dynamic, so the interface of not actual embodiment, Entry and R1 are only to illustrate, handled by global resource The foundation of unit and the foundation of longitudinal interface, the network should be able to carry out the access and all kinds of basic services of user.

Horizontal interface be mainly handle equity Internet resources processing node between communication, such as between base station, cell Between etc..

On horizontal interface, due to control centralization, so be deployed on SNC relevant control face resource entity (such as NAS the communication interface (such as S10 interface in former LTE network) between) is changed to internal interface, and between other network elements and node Between network interface establish IP Tunnel as the horizontal interface (such as X2 interface) of traditional network due to not needing, so, In actual horizontal interface establishment process, it is only necessary to be adapted in the corresponding interface that interface adaptation module part is got through between RN (such as X2 mouthfuls of corresponding IP Tunnel).
