Description
Technical field
The present invention relates to mobile Internet field, relate more specifically to strategy and online charging control system.
Background technology
Along with development of Mobile Internet technology is in the fast development of telling data access field, smart mobile phone/panel computer and emerging application, terminal use based on cloud access and down load application in any place at any time easily, and these have greatly stimulated the use of Mobile data.Operator finds that their data service just increases with exponential manner.Third generation partner program (3GPP) has been developed comprehensive QoS, charging and policy control framework and has been met growing QoS, charging and policy control demand.(PCC) controlled in strategy and charging is the emphasis of the block core (EPC) of evolution, and has guaranteed the user experience quality of particular subscription and COS.
QoS based on consumption restriction in PCC structure and keying (gating) are controlled to be provided when consumption restriction has been used up or arrived to the packet of buying or limit dynamic reducing network QoS or has cut off one, the ability of several or all IP service for operator.The restriction of the consumption is here often referred to that currency restriction, number restriction or user be allowed to continues to subtract time restriction.
When reaching consumption restriction, terminal use needs defrayment to keep the QoS of common grade or to control data, services, otherwise, if defrayment is not with expansion consumption restriction for terminal use, terminal use's experience meeting is affected because of the QoS of lower grade or unaccepted service access.
QoS based on Spending Limit and keying have also protected terminal use to exempt from " bill shock " (BillShock).When arriving consumption restriction, lower QoS can not allow terminal use to consume to have the too many data of the expensive traffic carrying capacity of exceeding the time limit or cut off service with denied access in the situation that additionally not exceeding the time limit charge.
3GPP introduces Sy interface and controls to consume restriction QoS and gating between OCS and PCRF, but this triangle that has produced identical data session between PCEF, PCRF and OCS is mutual.This situation is unusual poor efficiency, and has produced many technical problems and business problem.
The present invention introduces a kind of efficient strategy and charging controls to support QoS and the gating based on consumption restriction. and the present invention has simplified current PCC structure and has not introduced extra signaling burden.Because Virtual network operator recognizes that PCC is more and more important in whole LTE EPC Core Solution.The present invention can support more flexible and effective PCC charging to control.
Current, 3GPP has defined very complicated strategy and QoS and the keying of charging control structure to implement to limit based on consumption.Fig. 1 shows 3GPP and limits the PCC solution for QoS and gate based on consumption.As shown in Figure 1, in this structure, between PCRF and OCS, introduced special-purpose Sy interface.Sy reference point can transmit about the information of customer consumption also from OCS to PCRF
And support following functions:
-policy counter status report request from PCRF to OCS,
-policy counter state change notification from from OCS to PCRF.
Along with introduce Sy interface between PCRF and OCS, produced the mutual (see figure 2) of triangle between PCEF, PCRF and OCS.The triangle that Fig. 2 illustrates between PCEF, PCRF and OCS is mutual.PCEF must communicate by letter to ask with PCRF qos policy, and PCRF also must be to the consumption restriction of OCS query counts device, after PCRF strategy decision, the QoS response PCEF of PCRF to authorize, then PCEF send credit request to OCS with application credit limit.
PCEF, the triangle between PCRF and OCS has produced many technical problems and coml shortcoming alternately:
Sy interface has increased the complexity of PCRF and OCS enforcement.PCRF and PCRF need to maintain Sy session information.Sy has also increased the flow burden in OCS.For same data session, OCS must monitor from the Sy session information of PCRF with from the Gy session of PCEF.Sy interface has been introduced communication cycle and on the consumption restriction point of arrival, has been introduced incorrect charging and rate information and incorrect QoS control and controlled.For example, client's plan is " before consumption restriction, call rate is X/ byte, has QoS 1, and after consumption restriction, call rate is Y/ byte, has QoS 2 ".When OCS receives CCRu report from PCEF, and it determines that having arrived consumption limits, because QoS 1 does not also change, OCS still distributes amount based on rate Y/ byte to PCEF, but the service that PCEF still allows to have QoS 1 (in fact, according to this plan, the network speed after consumption restriction will be QoS2).Meanwhile, OCS will send to consume to PCRF and limit arrival notice, and PCRF then determines new policing rule, then deletes the old strategy of old strategy foundation and PCEF.Because QoS changes, PCEF will generate another CCRu to OCS, and this can produce extra charging.Mutual these problems that also produce of triangle have formed challenge to current PCC structure.The present invention has introduced efficient strategy and charging controls to support QoS and the gate based on consumption restriction.The present invention has simplified current PCC structure and has made the signaling traffic burden between PCEF, PCRF and OCS and minimize alternately.
