Description

A kind of method of communications network system and searching Home eNodeB strategy NE
Technical field
The present invention relates to communication technical field, be specifically related to a kind of communications network system and find the method for Home eNodeB strategy NE.
Background technology
Third generation partner program (3rd Generation Partnership Project, referred to as 3GPP) grouping system (the Evolved Packet System of evolution, referred to as EPS) by universal mobile telecommunications system land radio access web (the Evolved Universal Terrestrial Radio Access Network of evolution, referred to as E-UTRAN), mobile management unit (Mobility Management Entity, referred to as MME), gateway (Serving Gateway, S-GW), grouped data network gateway (PacketData Network Gateway, referred to as P-GW or PDN GW), home subscriber server (HomeSubscriber Server, referred to as HSS), authentication and authorization charging (the Authentication of 3GPP, Authorization and Accounting, referred to as AAA) server, "Policy and Charging Rules Function (Policy and Charging Rules Function, referred to as PCRF) entity and other support nodes composition.
Fig. 1 is the schematic diagram of the system architecture of EPS according to correlation technique.As shown in Figure 1, Mobility Management Entity is responsible for the related work of the chain of command such as process and the contextual management of user's mobile management of mobile management, Non-Access Stratum signaling; S-GW is the accessing gateway equipment be connected with E-UTRAN, forwarding data between E-UTRAN and P-GW, and is responsible for carrying out buffer memory to pending datas such as pagings; P-GW is then the borde gateway of EPS and packet data network (Packet Data Network, referred to as PDN) network, be responsible for PDN access and between EPS and PDN the function such as forwarding data; S-GW and P-GW belongs to core network gateway; PCRF is "Policy and Charging Rules Function entity, it is by receiving interface Rx and carrier network agreement (Internet Protocol, referred to as IP) business network be connected, obtain business information, in addition, it is connected with the gateway device in network by Gx/Gxa/Gxc interface, be responsible for the foundation initiating IP carrying, ensure the service quality (Quality of Service, referred to as QoS) of business datum, and carry out charging control.
EPS supports the intercommunication with non-3 GPP system, and wherein, pass through S2a/b/c Interface realization with the intercommunication of non-3 GPP system, P-GW is as the anchor point between 3GPP and non-3 GPP system.In the system architecture diagram of EPS, non-3 GPP system is divided into trusted non-3 gpp IP access and trustless non-3 gpp IP accesses.Trusted non-3 gpp IP is accessed and can be directly connected with P-GW by S2a interface; Trustless non-3 gpp IP access need through the packet data gateway of evolution (Evolved Packet Data Gateway, referred to as ePDG) be connected with P-GW, interface between ePDG and P-GW is S2b, S2c provides subscriber equipment (User Equipment, referred to as UE) control relevant to the user face between P-GW and mobility support, its mobility management protocol supported is the mobile IP v 6 (Moblie IPv6Support for Dual Stack Hosts and Routers, referred to as DSMIPv6) supporting two stack.
Among EPS, strategy and charge execution function (Policy and Charging EnforcementFunction, referred to as PCEF) entity are present in P-GW, Gx interface (see Fig. 1) exchange message between PCRF and P-GW.When interface when between P-GW and S-GW is based on PMIPv6, S-GW also has bearing binding and event reporting function (Bearer Binding and Event Report Function, referred to as BBERF) entity carries out QoS control to business data flow, by Gxc interface (see Fig. 1) exchange message between S-GW and PCRF.When by the access of trusted non-3 GPP access system, the trusted non-3 GPP access network Central Shanxi Plain also resident BBERF.By Gxa interface (see Fig. 1) exchange message between trusted non-3 GPP access gateway and PCRF.When UE roams, S9 interface is as the interface of ownership place PCRF and visited place PCRF, simultaneously for UE provides application function (the Application Function of business, referred to as AF), sent the business information being used for generating strategy with charging control (Policy andCharging Control, referred to as PCC) strategy to PCRF by Rx interface.In 3 gpp, corresponding PDN network can be found by APN (Access Point Name, referred to as APN).Usually UE to PDN network connection is called that an IP connects Access Network (IP Connectivity AccessNetwork, referred to as IP-CAN) session.In the process setting up IP-CAN session, BBERF and PCEF respectively and set up Diameter session between PCRF, transmits the policy, billing information that controls this IP-CAN session and the information etc. for generating strategy by these Diameter sessions.
BBF (Broadband Forum Broadband Forum) corresponding with it proposes broadband policy and controls framework BPCF (Centralized Deployment Functional Architecture centralized deployment function structure), as shown in Figure 2, BPCF major function formulates corresponding strategy; PEF (Policy EnforcementPoint Policy Enforcement Point) resides in fixed network transmission equipment usually, such as: BRAS (BroadbandRemote Access Server BAS Broadband Access Server)/BNG (Broadband Network Gateway), the corresponding strategy formulated according to BPCF performs; AAA (accounting server is authorized in Authentication, Authorization andAccounting certification), stored user CAMEL-Subscription-Information.AF (ApplicationFunction service application function), for BPCF generates strategy, provides corresponding business information.In fixed network, implementation strategy controls, the difference comparing mobile network is, fixed network policy decision entity is except generating strategy with signing based on business, also need to do resource and admission control, according to the on-position of UE, what judge the data flow of UE flows through path, thus judges based on to the resource on this path, whether receives this business.
FMC (the Fixed Mobile Convergence fixed network mobile fusion) scene that present operator pays close attention to very much, studies based on interconnecting to 3GPP and BBF exactly.As shown in Figure 3, give UE and access EPS core net schematic diagram by fixed network BBF.For the scene of user by BBF fixed network access mobile core net, be need the QoS on the routed path to whole data (data can be transmitted through fixed network and mobile network) to ensure.When mobile subscriber UE is by the access of BBF fixed network, PCRF not only needs to generate strategy with signing based on business, also needs to pass through S9 *(between PCRF and BPCF) interface initiates call access control request to BPCF (may contain customer location in request message, the information of mark and so on is for informing the on-position of BPCF user), the step that existing PBCF does call access control is as follows, comprising:
The first step, identifies the on-position of UE;
Second step, what judge UE data flow flows through path, such as: RG (Residential Gateway home gateway), AN (Access Note such as: DSLAM Digital Subscriber Line AccessMultiplexer Digital Subscriber Line access and multiplexing device), the equipment such as BRAS (Broadband Remote AccessServer BAS Broadband Access Server)/BNG (Broadband Network Gateway).
3rd step, judges the resource situation of each node on path, if resource can meet the requirement of this data flow on node, after allowing to receive BPCF to complete call access control decision-making, returns results to PCRF.Therefore, BPCF does the access relevant information that call access control relies on user UE, and PCRF can pass through S9 *inform BPCF.
As shown in Figure 4, give UE and access EPS core net schematic diagram by 3GPP Femto mode.For the scene of UE by H (e) NB (Home eNodeB) access (3GPP Femto mode accesses), when H (e) NB powers on, H (e) NB can obtain the IP address distributed by fixed network BBF, be deployed with difference due to actual Operation Network, the method for salary distribution of IP address exists following 2 kinds (difference is that the functional mode disposing home gateway RG is different: bridge joint mode and routing mode):
The first, routing mode
As shown in Figure 5, UE accesses RG by H (e) NB, BRAS/BNG is accessed after being converged by AN, RG is now as routing mode, the IP address of UE is distributed (such as: H (e) NB accesses RG by RG, adopt mode certification on RG of user name password, authentication success RG is that H (e) NB distributes home address), and the IP address of RG is distributed (such as: when RG powers on by BRAS/BNG, RG initiates certification to BRAS/BNG, BRAS/BNG is this RG allocation address), now RG needs to do IP address transition, the private net address of H (e) NB is converted to public network address CPE (CustomerPremise Equipment--customer premises equipment, CPE/ustomer premises access equipment) address, this address can be BRAS/BNG is the address that RG distributes.
The second, bridge joint mode
As shown in Figure 6, (in network design, may RG be there is in UE by H (e) NB access, if existed, RG now has bridging functionality, RG is a two-layer equipment, be not user's distributing IP address, and the connection between H (e) NB and BRAS/BNG is the connection of two layers), access BRAS/BNG by AN again, the IP address of this H (e) NB is distributed by BRAS/BNG.
Prior art proposes, and can access for 3GPP Femto, sets new network element H (e) NB PF (Policy Function, policing feature), as shown in Figure 7, for the call access control under this scene; IP-sec tunnel (IP-Sec secure tunnel ensures the encryption safe in data transmission procedure) can be set up, the tunnel information (comprising: the IP address of tunnel outer and/or port) in this tunnel between security gateway Sec-GW and Home eNodeB H (e) NB.If home gateway RG is routing mode, IP address due to H (e) NB now may be the internal address that RG distributes, Sec-GW needs to transmit CPE IP address and H (e) NB IP address (this CPE IP address is the outside ip address in tunnel, and H (e) NB IP address is implicit IP address) to H (e) NBPF; If home gateway RG is bridge joint mode, the address of H (e) NB is the address distributed by BRAS/BNG, Sec-GW transmits the IP address information of H (e) NB to H (e) NB PF, can transmit CPE IP address (now the IP address of CPE may be consistent with the IP address of H (e) NB).
As shown in Figure 8, corresponding H (e) NB GW/MME needs the IP address of QoS information (such as: bandwidth) and H (e) NB to pass to this H (e) NB PF (real network may not exist H (e) NBGW in disposing, and now MME transmits QoS information).Certainly except above-mentioned H (e) NB GW/MME transmits QoS information, as shown in Figure 9, another kind of mode is also had: the IP address oneself being reported QoS information and H (e) NB by H (e) NB.The tunnel information of acquisition and QoS information are given BPCF by H (e) NB PF thus, and BPCF just can judge the position of H (e) NB according to tunnel information, then do call access control according to the resource of QoS information to request.
In prior art, for having the selection of multiple "Policy and Charging Rules Function entity PCRF in network by network element DRA (Diameter Routing Agent, Diameter route entity) realize, DRA ensures that multiple sessions of same IP-CAN session or a UE are processed (such as: according to APN information) by same PCRF; And when there is multiple H (e) NB PF in network, all sessions under same H (e) NB need to be processed by H (e) NB PF, how ensureing being that Sec-GW and H (e) NB GW/MME/H (e) NB that H (e) NB serves finds same H (e) NB PF, is the problem that the present invention needs to solve.
