Fig. 2 is the schematic diagram according to the NACF network architecture of correlation technique, as shown in Figure 2, NACF is by AR-FE (Access Relay Functional Entity, the access relay function entity), AM-FE (Access Management Functional Entity, the access management function entity), TAA-FE (Transport Authentication and AuthorizationFunctional Entity, the certified transmission authorization function entity), NAC-FE (NetworkAccess Configuration Functional Entity, the network access configuration function entity), TUP-FE (Transport User Profile Functional Entity, transmission user list function entity), HGWC-FE (Home Gate Way Configuration FunctionalEntity, home gateway configuration feature entity) and TLM-FE (Transport LocationManagement Functional Entity, transmission location management function entity) constitute.In addition, also show business control function body, ustomer premises access equipment, PD-FE, transfer function entity, other next-generation communication network etc. among Fig. 2.
In NACF, the realization relay function of AR-FE between CPE (Customer Premises Equipment, ustomer premises access equipment) and NACF, AR-FE receive the network insertion request from CPE, and this request is transmitted to AM-FE among the NACF; AM-FE transforms the network insertion request that the user sends, IP address assignment and possible network parameter configuring request are sent to NAC-FE, and,, and obtain user-dependent access configuration parameter by the mandate of TAA-FE checking user, discrimination natwork access to TAA-FE transmission access request; TAA-FE carries out user rs authentication, carries out the network insertion mandate based on user's inventory TUP-FE of transport layer, and will be stored in from checking, the authorization message of user's inventory among the transport layer location management function entity TLM-FE.NAC-FE is responsible for user's distributing IP address, network configuration parameters etc. is provided, play DHCP (Dynamic Host Configuration Protocol, DHCP) effect of server or RADIUS (Remote Authentication Dialin User Service, the service of long-distance user's insertion authority) server; TUP-FE storage user's authentication, authorization data and the relevant database of information of network insertion configuration.HGWC-FE offers additional configuration information such as subscriber-related interior firewall control and QoS when home gateway (Home Gateway) initialization and renewal.TLM-FE record the IP address of distributing to client device CPE and the network location information that provides by NAC-FE between association, network location information and address location information between association, customer identification number, the QoS configuration of user network and the selection of subscriber-related location privacy.
ITU-T has introduced the mobility support at NGN R2 version, suggestion increases moves the relevant function of control, comprise LMF (Location Management Function, location management function) and HCF (Handover Control Function, switching control function).LMF be mobile node between access node when mobile, the position that can upgrade in time, thus the positional information of mobile node is provided for the relevant business in position, upper strata; HCF switches relevant authentication access and the relevant control of resource to ongoing session in the mobile node moving process, thereby makes the user can carry out Operational Visit incessantly under network control.
In the current version of NGN, just the network that moves of explanation support needs the function of supporting location management and handover management, but does not provide concrete implementation method, does not also provide the interface relationship between the current entity of itself and NGN.
NGN is based on the network of IP, and IETF (Internet Engineering Task Force, the Internet engineering duty group) is the normal structure of IP network standard formulation.IETF (InternetEngineering Task Force, the Internet engineering duty group) two kinds of mobility that different schemes is come the network enabled layer have been provided, thereby make upper layer application have ambulant support, and needn't each application all need to carry out separately mobility control.A kind of mobile IP that is based on main frame (Host-Based) of these two kinds of schemes, representing agreement is MIP4 (Mobile IPv4), MIP6 (Mobile IPv6); Another kind is based on the mobile IP of network (Network-Based), and representing agreement is PMIP (Proxy Mobile IP).The mobile IP that the difference of these two kinds of agreements is based on main frame needs mobile node to increase mobile IP function, initiates the relevant signaling of mobile IP; And based on network mobile IP does not need mobile node to increase mobile IP correlation function, replaces mobile node to initiate to move relevant signaling by network side, thus the mobility of support node.
Mobile IP and certain specific access technology are irrelevant, and CPE communicates with the outside by HoA (HomeAddress, home address).In Host Based mobile IP, CPE can have an interim CoA (Care of Address, Care-of Address), thus the data that make the PERCOM peripheral communication node send to HoA are forwarded to the network segment at CoA place by the tunnel via HA (Home Agent, home agent).In based on network mobile IP, MAG (Mobility Access Gateway, Mobile Access Gateway) can act on behalf of CPE and move relevant signaling, create MAG and LMA (Local Mobility Anchor, local mobile management anchor point) tunnel between, thereby make MAG after the data that receive from LMA, send the data to CPE.
In NGN, if network authenticates the user, finished mandate, and the user has been carried out necessary IP disposed, the TLM-FE of then recording user session (session) current state can pass through according to authentification of user, address configuration is finished the different conditions conversion, when these two requirements are all satisfied, the user session state of TLM-FE record has just entered Active (activation) state, at this moment, TLM-FE notifies this user's session to be in the Active state to RACF, the user can initiate communication, and the PERCOM peripheral communication node also can be initiated communication to the user, and network can manage this user's use resource.RACF and service control layer can also be to the TLM-FE customized messages, when position among the TLM-FE, RACF access point, access network type, initial network strategy, user's QoS configuration and user leave etc. when depositing subscriber-related information and changing, TLM-FE will be to RACF and SCF (Service Control Function, service control function) entity is notified, thereby RACF and SCF handle accordingly.
Mobile IP has increased the function of HA, FA (ForeignAgent, Foreign Agent) and MAG newly with respect to original NGN framework, and has expanded the mobility support of CPE.Though mobile IP has solved the mobility of network layer, but under the framework of NGN, mobile IP and current network are adhered to, also there are problems between resource and admission control and the mobile service control, wherein be, current NGN design is based on fixed terminal and roaming terminal formulation, user's session status has only initial condition, address configuration is finished with authentification of user and is passed through state, do not have and mobile relevant session control, that is, the current NGN ambulant session control that can not provide support, therefore, if mobile IP is used for controlled manageable NGN network, also needs to carry out control corresponding.
