Description
Technical field
The present invention relates to the communications field, method for ensuring service quality continuity when relating more specifically to switch between a kind of system.
Background technology
NGN (Network Generation Network, next generation network) is a hot research problem in current communication standard field, and it adopts the technology of dividing into groups such as IP as communication of Bearer Network converged fixed and mobile communication.
Among the NGN, because bearer network has adopted group technology, particularly IP is technological, and (Quality of Service, QoS) problem of aspect is especially outstanding in service quality to make NGN.Therefore, how providing end to end, QoS will be one of key problem of NGN.
TISPAN (Telecommunication and Internet converged Services and Protocolsfor Advanced Networking; Be used for the communication of high-level network and the business and the agreement of internet converged) from the fixing angle that inserts; The QoS problem that RACS (Resource and Admission ControlSubsystem, Resource and Admission Control Sub-system) solves the NGN bearer network has been proposed.RACS is one of NGN part; It is associated the resource requirement of operation layer (like IMS) with the resource allocation of network carrying layer; Functions such as main completion policy control, resource reservation, admittance control, NAT (NetworkAddress Translation, network address translation) pass through.RACS is the control service that application function provides transport layer through a series of qos policys, makes user terminal can obtain the business that required QoS guarantees.
3GPP (The 3rd Generation Partnership Project, third generation partner program) then inserts angle from moving, in up-to-date 3GPP R7 draft; (the Policy Decision Function of the policy control functions in the R6 version; PDF) and based on the billing function that flows (Flow BasedCharging FBC) merges, and has proposed PCC (Policy Control and Charging; Policy control and charging), accomplish resource accommodating control function.PCC realizes certain QoS controlling mechanism to the characteristic that moves Access Network between service control layer and access/bearing bed, the function that mainly provides has: control, control based on the charging of business data flow based on the customization information of user implementation strategy.
There is very big-difference in " the resource and admission control " that the various criterion tissue proposes aspect framework, network range and the node type that relates to.Carry out brief account with regard to TISPAN RACS and 3GPP PCC respectively below.
The function structure of TISPAN RACS is as shown in Figure 1.RACS is made up of two entities: SPDF (Service-based Policy Decision Function; Strategy decisive function based on business) and Access-Resource and Admission Control Function (Access-Resource and Admission Control Function, accommodating access resource controlled function).SPDF provides unified interface to operation layer, and the concrete access style of shielding bottom-layer network topological sum provides the policy control based on business.Access-Resource and Admission Control Function control Access Network has the function that control of admitting and network strategy converge.From SPDF reception request, realize admitting control based on the strategy of being preserved, acceptance or refusal are to the request of transfer resource.Access-Resource and Admission Control Function obtains network attachment information and user QoS inventory information through the e4 interface from NASS (NetworkAttachment SubSystem, Network Attachment Subsystem).
Comprise two kinds of functional entity: BGF (Border Gateway Function, Border Gateway Function) and RCEF (Resource Control Enforcement Function, Resource Control Enforcement Function) in the transport layer.BGF is one and wraps packet gateway, can between Access Network and core net, be called Core BGF, (C-BGF), realizes Core Border Gateway Function; Also can between two core net, be called Interconnection BGF (I-BGF), realize interconnected Border Gateway Function.BGF accomplishes under the control of SPDF that NAT passes through, gate, QoS mark, bandwidth constraints, use measurement and source synchronous function.RCEF implements two layers/three layers (L2/L3) Media Stream strategy that Access-Resource and Admission Control Function sends through the Re interface, accomplishes functions such as gate, QoS mark, bandwidth constraints.
The function structure of 3GPP PCC is as shown in Figure 2.PCRF (Policy and Charging RuleFunction, strategy and charging rule functions) comprises the policy control decision-making and by the flow based charging controlled function.PCRF provides towards detection, gate, the QoS of the relevant business data flow of PCEF (Policy and Charging Enforcement Function, strategy and charge execution function) and has pressed the network control function of flow based charging (except the credit rating management).PCEF comprises that business data flow detects, strategy is implemented and by the flow based charging function.This functional entity is positioned at gateway.PCEF provides business data flow detection, user plane traffic to handle, trigger control plane session management, QoS enforcement, business datum flow measurement and mutual with charge system.SPR (Subscription Profile Repository, signatory inventory storehouse) has stored user contracting data.OCS (Online Charging System) and OFCS (Offline Charging System) are respectively Online Charging System and off-line accounting system.
When the UE of bimodulus (User Equipment, subscriber equipment) move to insert and fixing the access between when moving be PCC because mobile network lays, be RACS and fixed network is laid, therefore need to consider switching between the two, to guarantee professional continuity.
Current, TISPAN is from fixing access, resource and admission was controlled when research UE moved method and flow process under fixing the access.3GPP is then from moving access, the method and the flow process of resource and admission control when research UE moves under moving access.TISPAN and 3GPP all do not carry out as yet UE move to insert and fixing the access between when moving, the research of switching between RACS and PCC.Under existing conditions, when UE moves, can't guarantee the continuity of business between mobile access and fixing the access.
Summary of the invention
The present invention proposes method for ensuring service quality continuity when switching between a kind of system, guaranteed the continuity of business when UE moves between mobile access and fixing the access.
The present invention has also used mobile IP of the prior art.The entity that mobile IP relates to has HA (HomeAgent, home agent), FA (Foreign Agent, Foreign Agent) and mobile node.
HA is the main frame or the router that are connected to the mobile node local network; It preserves the positional information of mobile node; When mobile node leaves home network, can the packet that mail to mobile node be sent to FA through the tunnel, hand to mobile node by FA then.FA is main frame or the router on the field network at the current place of mobile node, and it can be transmitted to mobile node to the packet of being sent here by HA.
