Abstract
The invention discloses an inter-field consultative method that ensures end-to-end service quality, which includes: step A, when the session authorization from the access network to the terminal multi-media subsystem is over, the terminal sends service quality signal to the equipment on the session end before media transmission between the two ends; step B, the service quality signal passes through the external IP backbone network with service quality control function; service quality consultation is conducted between the IP backbone network and the access network; step C, the service quality signal reaches the equipment on the opposite end of the target network. PDP of the access network does not require configuration of BCF information of the external IP backbone network, nor does it need to recognize the relations between the PEP in the session path and the external IP network. When multiple IP backbone networks exist on the session path, this advantage is more obvious; when the IP backbone network on the session path doesn't have QoS capability, the QoS signal will pass transparently without being processed thus bringing no impact to the consultation process.
Description
Technical field
The present invention relates to service quality (Quality of Service, QoS) assurance of the third generation (The 3rd Generation) mobile communcations system.Relate in particular to a kind of core network side that arrives, end-to-end quality of service guarantees and inter-domain negotiation method.
Background technology
Along with the development of wireless technology, mobile communication can not only provide traditional speech business, and various multimedia application are provided simultaneously.Under this background, 3GPP and 3GPP2 organize all the IP multimedia subsystem, IMS that successively proposed based on the ALL IP network (IPmultimedia subsystem, IMS).IMS is the call control system of an application layer, and it is to be superimposed upon packet domain (PacketSwitch is on PS).In this system, IMS provides the signaling control of the application layer of session, and PS is responsible in the territory providing carrying.
That Fig. 1 has shown is end-to-end (End-to-End, in IMS session E2E), the overall construction drawing between IMS territory and the PS domain network element.During the simplification, a lot of and incoherent network element of the present invention has all omitted.Among the figure, what dotted line was represented is signaling flow, and what solid line was represented is Media Stream.
Session QoS guarantees it finally is to lean on the bearer network of bottom to realize.In the negotiation of IMS session, IMS application layer use authority mechanism is finished the control to the bearing resource of bottom.Application layer can be passed through policy decision point to the mandate of carrying, and (PolicyDecision Point, (Policy Enforcement Point, PEP), the final realization of the policy enforcement point PEP of access network controlled session QoS PDP) to be sent to policy enforcement point.In the 3GPP standard, this licensing scheme be defined as local policy based on business (Service Based Local Policy, SBLP), in the 3GPP2 standard, this licensing scheme be defined as based on the carrying of strategy control (Service Based Bearer Control, SBBC).In this licensing scheme, policy decision point PDP can be the network element strategy decisive function (Policy Decision Function, PDF), or "Policy and Charging Rules Function (Policy and Charging Rule Function, PCRF); In the 3GPP standard, policy enforcement point PEP can be the GGSN network element, and in the 3GPP2 standard, policy enforcement point PEP can be the AGW/PDSN network element.
The medium of session finally will be exhaled network rising, and transmit between IP backbone network and the end call network.
Present problem is: rise exhale with end call network in, QoS is can be guaranteed; But the network branch of working as session two ends is in two territories and this two territories do not have direct physical connection, need connect by one or more external IP backbone networks.At this moment, how qos policy being applied to the external IP backbone network, satisfying the demand of QoS to guarantee the resource on the end-to-end path, is a very important problem.
We can see in Fig. 1, and in the process of IMS session, the external IP backbone network does not participate in.What in fact IMS signaling and medium may pass through is different external IP backbone networks.Therefore, in order to guarantee QoS demand end to end, QoS negotiation mechanism between a kind of effective territory must be arranged.
In the prior art, to Access Network fall and the IP backbone network between QoS consult that 4 kinds of methods are arranged, wherein first method is the participation that does not need qos signaling, then three kinds all need qos signaling to consult:
1, the PS territory does not have qos signaling
This method is as shown in Figure 2, be characterized on media path end to end, between the IP backbone network, IP backbone network and pulbic land mobile network (public land mobile network, PLMN) there has been the QoS relation to have the (service level agreement that consults in advance (Service Level Agreement between in advance, SLA)), do not need to consult QoS temporarily.Its general configuration of adopting static state.
The defective of this method is: in this pattern, the IP backbone network does not have resouce controller, and this can provide the network that service quality guarantees for one and be improper, and the QoS relation can only static configuration can not dynamic negotiation, do not have flexibility;
2, Off-Path model, offline mode
This method is as shown in Figure 3, and (BearerControl Function BCF), is used for the management and the distribution of resource to be characterized in a resouce controller-bearer control function being arranged the IP backbone network.The feature of this kind framework is: strategic decision-making node PDP links to each other with outer net resouce controller BCF, finishes the mutual of signaling decision-making level and consults, and signaling is separated at two passes with data.Rise exhale and end call network between the path on, may have a plurality of IP backbones, each IP backbone network has resouce controller BCF separately.
The defective of this method is:
May need to build separately signaling network between BCF and PDP, engineering is very big.
Policy decision point PDP need be the function of OFF-PATH mode expansion oneself, as disposes all outer net resource manager information, and corresponding route.
Policy decision point PDP need know which IP backbone network can appear at end to end on the path, and PDP can know that just the BCF with which external network holds consultation like this.This configuration will be very complicated.
3, On-Path pattern
This method is as shown in Figure 4, be characterized in: resouce controller is not set in the IP backbone, inter-domain resource is consulted to be initiated to the edge router of external network by responsible network elements to outer net transmission data medium such as PEP, and signaling paths is the same with the data medium path.At present main QoS consults signaling and the negotiation means comprise use RSVP serial protocols, MPLS-TE agreement and reaction type machinery of consultation.
The defective of this method is: this method has solved the PS territory does not have static configuration problem in the qos signaling pattern, is still its defective but lack QoS control network element in the IP network.
4, Hybrid hybrid mode
This method is as shown in Figure 5, is characterized in: to direct-connected and responsible network element to outer net transmission data medium is configured with outer net in the Access Network, it is possessed with the outer net resouce controller carry out the function that QoS consults.This network element is initiated the bearing resource request to outer net resouce controller BCF, and can consult to decide data flow by both party obtain the access permission on the network externally.
The defective of this method is: though this method has solved some problems of off-path pattern.But some major defects of off-path pattern still exist: need be in PEP the BCF of configuration of IP backbone network, how to judge which IP backbone network can appear on the path.
