Description

Under the PCC framework to the processing method and the equipment of message

Technical field

The present invention relates to the mobile communication technology field, relate in particular to a kind of strategy and the control of chargeing (Policy and Charging Control, PCC) under the framework to the processing method and the equipment of message.

Background technology

Along with the development of mobile communication, class of business is ever-changing.See that from operator's angle the situation of the shared Internet resources of different service is different, need to implement the different QoS control and the control of chargeing to different business.The PCC framework be based on business data flow (service data flow) level other, policy control and charging controlled function based on business data flow are provided.

In the PCC framework, (User Equipment is UE) through setting up IP connected reference network (IP-Connectivity Access Network for subscriber equipment; IP-CAN) (the Packet Data Network of session connection Packet Data Network; PDN), an IP-CAN session comprises one or more IP-CAN and carries (IP-CAN bearer), and it is to have defined speed that IP-CAN carries; Postpone the IP transmission channel of attributes such as the error rate.

The PCC framework provides binding mechanism (Binding Mechanism), promptly confirms the corresponding relation that business data flow and IP-CAN carry.In binding mechanism, need be the PCC rule (PCC Rule) and IP-CAN session association of each business data flow and configuration thereof at first, afterwards again with PCC Rule and IP-CAN bearing binding with operator.After binding, a PCC Rule is tied to an IP-CAN and carries, and an IP-CAN carries and can bind a plurality of PCC Rule.

Main network element in the PCC framework comprise "Policy and Charging Rules Function (Policy and Charging Rules Function, PCRF), strategy and charge execution function (Policy and Charging Enforcement Function, PCEF).Interface between PCRF and the PCEF is the Gx interface, and PCEF can be through the Gx interface to PCRF request PCC Rule, and PCRF issues PCC Rule through the Gx interface to PCEF.After PCEF obtains PCC Rule, after receiving message, can at first confirm the PCC Rule corresponding and adopt this PCC Rule that message is carried out the QoS control and the control etc. of chargeing with message.Wherein, Can be that the business datum flow filter (service data flow filter) that defines in according to PCC Rule is compared with content of message when confirming the corresponding PCC Rule of message; If the business datum flow filter of a certain PCC Rule is identical with the content of message of reception, then can confirm as is the corresponding PCC Rule of message that receives.

Can find out from foregoing description, be to carry out QoS control and according to the control of chargeing of the charging relevant parameters among this PCC Rule according to the QoS relevant parameter among the same PCC Rule when in the prior art message being handled.And in practical application, may have different application scenes, and for example operator hopes to adopt different PCC Rule to carry out the QoS control and the control of chargeing respectively probably, and still, prior art can not adapt to the demand of different scenes.

Embodiment

For the purpose, technical scheme and the advantage that make the embodiment of the invention clearer; To combine the accompanying drawing in the embodiment of the invention below; Technical scheme in the embodiment of the invention is carried out clear, intactly description; Obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the present invention's protection.

Fig. 1 is the method flow sketch map of first embodiment of the invention, comprising:

Step 11:PCEF receives message;

Step 12:PCEF confirms the PCC rule that said message is corresponding according at least two types the PCC rule of obtaining.

Wherein, at least two types PCC rule can comprise: carry the PCC rule of other PCC rule of level and session-level, perhaps, be used for the PCC rule and the PCC rule that is used for policy control of bearing binding.

Comprise the PCC rule of carrying other PCC rule of level and session-level with the PCC rule, and will confirm that other PCC rule of the corresponding carrying level of message is example, confirms that corresponding other PCC rule of carrying level of message can comprise:

At first, from two types the PCC rule of obtaining, confirm that type is for carrying other PCC rule of level at least; For example; PCEF receives the PCC rule that PCRF sends, and the type of PCRF indication PCC rule when sending the PCC rule, and then PCEF is after receiving the PCC rule that PCRF sends; PCEF can confirm which PCC rule is for carrying other PCC rule of level; Which PCC rule is the PCC rule of session-level, can from a plurality of PCC rules, determine type for carrying other PCC rule of level, and this carries other PCC rule of level can be 1 or at least two.

Secondly,, said message and said type are mated for the business datum flow filter that carries other PCC rule definition of level, confirm other PCC rule of the corresponding carrying level of said message obtaining type for after carrying other PCC rule of level.For example; Type maybe be for more than two for carrying other PCC rule of level; The business datum flow filter of definition is different in each PCC rule; With message and business datum flow filter relatively after, it is regular that other PCC rule of carrying level at business datum flow filter place that will be consistent with content of message is confirmed as other PCC of the corresponding carrying level of message.That is to say that type possibly be a plurality of for carrying other PCC rule of level, but after overmatching, other PCC rule of the carrying level corresponding with message is one.

Further; Can also comprise: the PCC that obtains at least two types is regular, and this obtains and can be meant that PCEF receives the PCC rule of PCRF transmission and indicates the regular type of PCC by PCRF, perhaps; Obtain and also can be meant in the PCEF self configuration PCC rule, and the type of configuration PCC rule.Particularly, obtaining at least two types PCC rule can comprise:

Receive the PCC rule installation AVP of PCRF transmission and the regular content of PCC that will install, comprise the AVP of the type that is used to show the PCC rule that to install among the said PCC rule installation AVP; Perhaps,

Receive that PCC rule that PCRF sends is installed AVP and the content of the PCC rule that will install, comprise the AVP of the type that is used to show the PCC rule that to install in the content of the said PCC rule that will install; Perhaps,

The type and the content of the local predefined PCC rule of PCEF are set in advance.

Step 13:PCEF carries out the policy control of corresponding types and handles according to the PCC rule of said correspondence to said message.

Comprise that with the PCC rule PCC rule of carrying other PCC rule of level and session-level is an example, message carried out the policy control of corresponding types and handle and can comprise:

When said PCC rule of carrying other PCC rule of level and session-level is used for different strategies control; According to other PCC rule of said carrying level; Said message is carried out first policy control handle, said first policy control is treated to the predefined policy control that other PCC rule of level is used for of carrying; According to the PCC of said session-level rule, said message to be carried out second policy control handle, said second policy control is treated to the policy control that the PCC rule of predefined session-level is used for.

Wherein, different strategies control is meant that two types PCC rule is used for dissimilar control.For example; Which kind of policy control is the PCC rule that can preestablish which kind of type be used for, concrete as, preestablish and carry other PCC rule of level and be used for QoS control; The PCC rule of session-level is used for the control of chargeing; After then obtaining the PCC rule of the corresponding session-level of other PCC rule of the corresponding carrying level of message and message, will carry out QoS control according to corresponding other PCC rule of carrying level of message, and according to the control of chargeing of the PCC rule of the session-level of message correspondence.

On the other hand, have the identical time spent of doing with the PCC rule of session-level carrying other PCC rule of level, relatively carry the priority of the PCC rule of other PCC rule of level and session-level, the PCC rule that employing priority is high is carried out the strategy processing to message.Wherein the identical effect here is meant that PCC rules dissimilar in the predefined policy control can accomplish with a kind of control.For example; When preestablishing, carry other PCC rule of level and can be used for the control of chargeing; The PCC rule of session-level also can be used for the control of chargeing; When message being chargeed control, at first need the priority of the PCC rule of other PCC rule of relatively carrying level and session-level so, select the high PCC rule of priority to carry out accounting processing.

Particularly, if the message that receives is a uplink message, then, confirm the PCC rule that uplink message is corresponding according to the regular type and the content of PCC of uplink message and uplink message place IP-CAN bearing binding.If the message that receives is a downlink message; Then according to the type and the content of the PCC rule of downlink message and downlink message place IP-CAN binding session; Confirm that the corresponding IP-CAN of downlink message carries and corresponding PCC rule, wherein the PCC rule of IP-CAN binding session is meant the PCC rule of all IP-CAN bearing bindings in the IP-CAN session.

In addition, different with prior art is that message only can uniquely match a PCC rule in the prior art, carries out Unified Treatment based on this PCC rule then, for example carries out QoS control based on this PCC rule, the control of chargeing, bearing binding etc.And in the present embodiment, this has expanded the range of application of PCC rule, is about to the PCC rule and is divided into polytype.When message matees, need mate, can obtain polytype PCC rule, adopt different PCC rules to carry out the different strategies control and treatment respectively afterwards, rather than accomplish all processing by single PCC rule according to the type of PCC rule.For example; Can the PCC rule be divided into the PCC rule that is used for bearing binding, the PCC rule of the control that is used to charge and be used for the PCC rule of QoS control; Can the message that receive be mated with above-mentioned three types PCC rule respectively afterwards; Obtain three corresponding PCC rules, three PCC rules that adopt coupling to obtain are again carried out bearing binding, charging control, QoS control respectively.Again for example, then above-mentioned will carry out bearing binding and charge control and QoS control the time if a kind of PCC rule is used for QoS control and the control of chargeing simultaneously, only need twice of coupling.

That is to say; The just fixing single type of PCC rule of the prior art, fixing single type can not satisfy the needs of different scenes, and in the present embodiment; The PCC rule is expanded; Make the PCC rule have different types, under different scenes, can adopt the combination of dissimilar PCC rules like this, can satisfy the flexile service deployment requirement of operator.

Present embodiment makes the PCC rule have different types through the PCC rule is expanded, and based on dissimilar PCC rules message is carried out the different strategies control and treatment, can adapt to the demand of different scenes.

In the embodiment of the invention,, can define dissimilar PCC rules in order to satisfy the demand of more scenes.Issuing the PCC rule with PCRF to PCEF is example, can adopt mode as shown in Figure 2 to make PCEF obtain and have dissimilar PCC rules.

Referring to Fig. 2, present embodiment comprises:

Step 21:PCRF sends the PCC rule to PCEF (Charging-Rule-Install) AVP is installed; This PCC rule is installed among the AVP and is comprised PCC Rule content (Charging-Rule-Definition) AVP, also comprises the AVP of the type that is used to show the PCC rule that will install.

Need not specify the type of PCC rule in the prior art, so the PCC rule is installed the AVP that also is not used in the type that shows the PCC rule that will install among the AVP in the prior art.And in the present embodiment, need newly-increased AVP in the AVP be installed in existing P CC rule, be used to show the type of the PCC rule that will install.

With the PCC rule serves as that the PCC rule of carrying other PCC rule of level or session-level is an example, and this newly-increased AVP can be called Session-Level-Indication.Therefore, the form of the rule of the PCC in present embodiment installation AVP can comprise following content:

Above-mentioned Session-Level-Indication is newly-increased AVP, is used to show that the PCC Rule that will install carries other PCC Rule of level or the PCC Rule of session-level.

In addition, PCRF issues consistency and the accuracy that Charging-Rule-Install AVP must guarantee PCC Rule type, otherwise PCEF makes abnormality processing.For example; When PCRF carries out bearing binding; If the Session-Level-Indication among the Charging-Rule-Install AVP is designated as other PCC Rule of session (Session) level, just should not comprise Bearer-Identifier AVP among the Charging-Rule-Install AVP so; Equally, if the Session-Level-Indication among the Charging-Rule-Install AVP is designated as other PCC Rule of carrying (Bearer) level, just need comprise Bearer-Identifier AVP among the Charging-Rule-Install AVP so.Above-mentioned example is to comprise that Bearer-Identifier AVP is an example, and the Session-Level-Indication of so above-mentioned example should indicate and carry other PCC Rule of level.

It is understandable that title, the data type of newly-increased AVP can specifically define, carry other PCC Rule of level or the PCC Rule of session-level as long as implication can indicate.

Optional, also can not comprise newly-increased AVP among the Charging-Rule-Install AVP, if do not comprise newly-increased AVP, the PCC Rule that then can give tacit consent among the Charging-Rule-Install AVP carries other PCC Rule of level.

Optional, also newly-increased AVP be can not comprise among the Charging-Rule-Install AVP, but carrying other PCC Rule of level or the PCC Rule of session-level indicated through existing AVP.

Further; Because it is to carry (Bearer) rank or session (Session) rank that Charging-Rule-Install AVP has increased the type of the PCC Rule in the AVP indication Charging-Rule-Install newly; If therefore PCRF issues carrying (Bearer) other PCC Rule of level and other PCC Rule of session (Session) level simultaneously in Diameter CCA/RAR message, Diameter CCA/RAR message need comprise a plurality of Charging-Rule-Install AVP so.

On the other hand, be example with the PCC rule for the PCC rule that is used for the professional PCC rule of controlling or be used for bearing binding, this newly-increased AVP can be called Rule-Type-Indication.At this moment, the form of the rule of the PCC in present embodiment installation AVP can be as follows:

Above-mentioned Rule-Type-Indication is newly-increased AVP, is used to show that the PCC Rule that will install is used for the PCC Rule of professional control or is used for the PCC Rule of bearing binding.Optional, also can specify a PCC rule both to be used for professional control and also be used for bearing binding.

Implication it is understandable that title, the data type of newly-increased AVP can specifically define, as long as can indicate PCC Rule that is used for professional control or the PCC Rule that is used for bearing binding.

Optional, also can not comprise newly-increased AVP among the Charging-Rule-Install AVP, if do not comprise newly-increased AVP, the PCC Rule that then can give tacit consent among the Charging-Rule-Install AVP is the PCC Rule that is used for bearing binding.

Further; Be used for professional control or be used for bearing binding because Charging-Rule-Install AVP has increased the type of the PCC Rule in the AVP indication Charging-Rule-Install newly; If therefore PCRF issues PCC Rule that is used for professional control and the PCC Rule that is used for bearing binding simultaneously in Diameter CCA/RAR message, Diameter CCA/RAR message need comprise a plurality of Charging-Rule-Install AVP so.

In addition; Above-mentionedly divide from granularity and purposes respectively; Further refinement for example also can still be the professional PCC rule of controlling that is used for of dialogue-based control through the PCC Rule that is used for professional control that AVP indicates corresponding PCC rule to be based on carrying control.

Above-mentioned PCC Rule content AVP can adopt definition of the prior art, and form can be following:

Can find out that from above-mentioned PCC Rule form the content of PCC rule comprises: business datum flow filter (flow-information) is used for comparing with content of message; Priority (precedence) is used for the matching order of confirming that PCC is regular; QoS-information is used for QoS control and bearing binding; " Service-Identifier " Rating-Group Online Offline Metering-Method is used for the control of chargeing.According to above-mentioned information, can confirm the PCC rule corresponding and carry out corresponding control with message.

Need to prove; Four kinds of PCC rules have been defined in the agreement at present; Be respectively dynamic (Dynamic) PCC rule of dynamically (Dynamic) PCC is regular, PCRF knows predefine (Predefined) PCC rule, the ignorant predefine of PCRF (Predefined) PCC rule and the control of non-operator, particularly, dynamic (Dynamic) PCC rule is provided through the Gx interface by PCRF; Filters has only three or four layers, can only be the Rule of L3/4.The predefine that PCRF knows (Predefined) PCC rule: pre-configured at PCEF, PCRF can only quote it, but can not revise it.The last predefined Rule of PCEF can assemble a Group, and PCRF can directly quote the set (Charging-Rule-Base-Name) of predefine Rule.Owing to be the local predefine rule of PCEF, therefore can expand the Rule definition of Gx interface, except supporting L3/4, can also increase the definition of L7.(L7 comprises application layer message, like http, wap, p2p) agreement.The ignorant predefine of PCRF (Predefined) PCC rule: at the pre-configured rules of PCEF, but PCRF and not knowing.Dynamic (Dynamic) rules of non-operator control: such as the Rule of flow map information (TFT) generation that provides according to UE of PCRF.

The PCC rule that the embodiment of the invention is directed against can be above-mentioned dynamic PCC rule and predefine PCC rule (comprising that PCRF knows with ignorant).For dynamic PCC rule, can specify through the said mode of present embodiment, for predefine PCC rule, directly Configuration Type on PCEF.

Above-mentioned through in Charging-Rule-Install AVP, comprising the AVP that is used to show the PCC rule type; Optional; Can Charging-Rule-Install AVP not changed yet; But in Charging-Rule-Definition AVP, comprise the AVP that is used to show the PCC rule type; To be used to show that corresponding PCC Rule carries other PCC Rule of level or the PCC Rule of session-level, be used to perhaps to show that corresponding PCC Rule is used for the PCC Rule of professional control or is used for the PCC Rule of bearing binding.

Present embodiment can handle laying the first stone for subsequent packet, to satisfy the demand of different scenes through the type of definition PCC rule.

When the type of PCC rule is the PCC rule of carrying other PCC rule of level or session-level, can adopt like Fig. 3 or handling process shown in Figure 4.

(1) carries other PCC rule of (Bearer) level: can only be installed in the IP-CAN carrying, must comprise being used for business datum flow filter (service data flow filter) and the qos parameter that business data flow detects.Remaining policy control, optional like the parameter of the control of chargeing.PCEF and PCRF only carry out bearing binding to carrying other PCC Rule of (Bearer) level; Business datum flow filter (the service data flow filter) conversion mapping that PCEF only will carry other PCC Rule of (Bearer) level is tied to corresponding IP-CAN loaded service flow template (Traffic Flow Template for this PCC Rule; TFT), PCEF sends to UE through signaling message with TFT.

(2) other PCC Rule of session (Session) level: be installed in interior all the IP-CAN carryings of IP-CAN session; Therefore PCEF and PCRF need not carry out bearing binding to other PCC Rule of session (Session) level, and PCEF need be with the TFT information of business datum flow filter (service data flow filter) conversion mapping for carrying of the type PCC Rule yet.Other PCC Rule of session (Session) level can not comprise qos parameter, perhaps also can comprise qos parameter, but PCEF need not carry out bearing binding to such PCC Rule according to qos parameter.Business datum flow filter (the service data flow filter) parameter that is used for the business data flow detection is optional; If do not comprise business datum flow filter (service data flow filter); Other policy control then will be to whole carrying granularity as chargeing control.

The general application scenarios of other PCC Rule of session (Session) level is in order to realize that each IP-CAN carries the service billing of unified granularity in the IP-CAN session, and need not be concerned about business data flow is in which concrete IP-CAN carrying.For example; Need http business data flow flat rate to each IP-CAN carrying in the IP-CAN session; So can be on PCEF PCC Rule of predefine; And the L7PCC Rule that to specify this PCC Rule be the http agreement, perhaps PCRF issues a PCC Rule, and to specify this PCC Rule be that port numbers is 80 L3/4PCC Rule.Other PCC Rule of session (Session) level can realize the application based on the service billing of Session flat rate, but is not limited in this.Therefore other PCC Rule of session (Session) level can support based on the control of whole session and the application scenarios that separates based on the PCC Rule that carries control based on the scope configuration and the maintenance of Session granularity.

Other PCC Rule of session (Session) level can have identical parameter with other PCC Rule of carrying (Bearer) level; For example carry other PCC Rule of (Bearer) level and all defined the relevant parameter of control of chargeing with other PCC Rule of session (Session) level; When user's message matees Rule so; Can all mate carrying other PCC Rule while of (Bearer) other PCC Rule of level and session (Session) level according to the priority of PCC Rule, carry out the control of chargeing according to the billing parameter of the high PCC Rule of priority.

If want to realize the application based on the service billing of Session flat rate according to other PCC Rule of session (Session) level, it is higher that the priority of other PCC Rule of session so (Session) level will be provided with.Another possibility is; Other PCC Rule is defined as the accounting processing that is exclusively used in the Session business with session (Session) level; Other PCC Rule of carrying (Bearer) level is defined as and is exclusively used in policy control; Carry other PCC Rule of (Bearer) level so and just need not comprise the charging relevant information, perhaps gateway is directly ignored the charging relevant parameters of other PCC Rule of carrying (Bearer) level.

Fig. 3 is the method flow sketch map of second embodiment of the invention, and present embodiment serves as the PCC rule of carrying other PCC rule of level or session-level with the PCC rule, and to receive uplink message be example.

Referring to Fig. 3, present embodiment comprises:

Step 31:PCEF receives uplink message.

Wherein, uplink message is meant that UE sends to the message of PCEF.

Step 32:PCEF confirms other PCC rule of the corresponding carrying level of uplink message.

Wherein, Can be all PCC rules of at first obtaining uplink message place IP-CAN bearing binding; Then according to the regular type of each PCC; Determine other PCC rule of all carrying levels of uplink message place IP-CAN bearing binding, afterwards, determine other PCC rule of a carrying level corresponding according to the priority and the business datum flow filter of PCC rule again with uplink message.Wherein the business datum flow filter can be confirmed according to " Flow-information " in the PCC rule, and priority can be confirmed according to " Precedence " in the PCC rule.

In addition, the binding that message and IP-CAN carry can be bound by PCRF, and at this moment, PCRF can notify binding relationship to PCEF, and the flow process that PCRF binds can be stipulated referring to existing protocol.Perhaps; The binding that IP-CAN carries also can be bound by PCEF; PCEF determines binding relationship after can the qos parameter that the qos parameter among the PCC Rule and each IP-CAN carry being compared, for example, if the QCI among the PCC Rule, APR are identical respectively with APR with the QCI that certain IP-CAN carries respectively; Then this PCC Rule and this IP-CAN carrying is a binding relationship, and wherein QCI and ARP are the parameters that comprises in the qos parameter.

Step 33:PCEF carries the policy control that other PCC rule of level is used for according to other PCC rule of the carrying level of determining corresponding with uplink message to uplink message.

For example, be used for QoS control, then can carry out QoS control according to " QoS-information " among other PCC Rule of the carrying level of determining if carry other PCC rule of level.

Wherein, to be used for which kind of policy control can be pre-configuredly to know to PCEF to every type PCC rule.

Step 34: if uplink message has passed through to carry the policy control of other PCC rule of level, PCEF confirms the PCC rule of the session-level corresponding with uplink message.

Wherein, can adopt the mode of similar step 32 to determine the PCC rule of the session-level corresponding with uplink message.

Step 35:PCEF is regular according to the PCC of the session-level corresponding with uplink message determined, and uplink message is carried out the policy control that the PCC rule of session-level is used for.

For example, the control if the PCC rule of session-level is used to charge then can be carried out accounting processing according to the charging relevant parameters in the PCC rule of the session-level of determining.

In addition, have identical effect if carry other PCC rule of level with the PCC rule of session-level, for example, the PCC rule of carrying other PCC rule of level and session-level may be used to charge, and after step 34, can also comprise so:

The priority of other PCC Rule of carrying level that the priority of the PCC Rule of the session-level that PCEF obtains coupling and step 32 coupling obtain is done comparison, selects the high PCC Rule of priority.Adopt the high PCC rule of this priority to carry out accounting processing afterwards.

Step 36: if uplink message has passed through the policy control of the PCC rule of session-level, the uplink message after then PCEF will handle is forwarded to PDN.

Fig. 4 is the method flow sketch map of third embodiment of the invention, and present embodiment serves as the PCC rule of carrying other PCC rule of level or session-level with the PCC rule, and to receive downlink message be example.

Referring to Fig. 4, present embodiment comprises:

Step 41:PCEF receives downlink message.

Wherein, downlink message is meant that PCEF sends to the message of UE.

Step 42:PCEF confirms other PCC rule of the corresponding carrying level of downlink message.

Wherein, Can be all PCC rules of at first obtaining all IP-CAN bearing bindings that the IP-CAN session of downlink message place comprises; Then according to the regular type of each PCC; Determine all and carry other PCC rule of level, afterwards, determine other PCC rule of a carrying level corresponding according to the priority and the business datum flow filter of PCC rule again with downlink message.

Other PCC rule of carrying level that step 43:PCEF is corresponding according to downlink message is confirmed downlink bearing.

For example, if the QCI that IP-CAN carries and ARP respectively with corresponding other PCC rule of carrying level of this downlink message in QCI and ARP identical, then downlink bearing is confirmed as in this IP-CAN carrying.

Step 44:PCEF carries the policy control that other PCC rule of level is used for according to other PCC rule of the carrying level of determining corresponding with downlink message to downlink message.

For example, be used for QoS control, then can carry out QoS control according to " QoS-information " among other PCC Rule of carrying level of correspondence if carry other PCC rule of level.

Step 45: if downlink message has passed through to carry the policy control of other PCC rule of level, PCEF confirms the PCC rule of the session-level corresponding with downlink message.

Particular content can be similar to the flow processing of step 34.

Step 46:PCEF is regular according to the PCC of the session-level corresponding with downlink message determined, and downlink message is carried out the policy control that the PCC rule of session-level is used for.

Particular content can be similar to the flow processing of step 35.

Step 47: if downlink message has passed through the policy control of the PCC rule of session-level, the downlink message after then PCEF will handle is carried on and carries out tunnel encapsulation and forwarding on definite downlink bearing.

In addition; Can also comprise in the present embodiment: PCEF is after obtaining other PCC rule of carrying level; With the TFT information of business datum flow filter (service data flow filter) conversion mapping for carrying of carrying in other PCC rule of level; And send to UE through signaling, so that UE can be according to the TFT information and the PCEF interaction data that carry.

Present embodiment is through being divided into the PCC rule PCC rule of carrying other PCC rule of level and session-level.A typical application scene can be when QoS controls, to adopt to carry other PCC rule of level, when chargeing, can adopt the PCC rule of session-level, can realize separating of the QoS control and the control of chargeing.

When the type of PCC rule is when being used for the PCC rule of bearing binding or being used for the PCC rule of professional control, can adopt like Fig. 5 or handling process shown in Figure 6.

(1) be used for the PCC Rule of bearing binding: must comprise being used for filters and the qos parameter that business data flow detects, with the carrying TFT and the QoS that generate behind the bearing binding, PCEF through signaling message with TFT that carries and QoS transmission UE; The parameter of control and other policy control (like gate) of chargeing is optional; In fact the PCC Rule that is used for bearing binding need not comprise these parameters; Even perhaps comprised; PCEF ignores and does not handle, because the PCC Rule that is used for bearing binding is used for carrying out based on the policy control of Business Stream and/or charges and control.

(2) the PCC Rule:PCEF that is used for professional control realizes based on the policy control (comprising QoS and gate) of business data flow and/or the control of chargeing according to this type of PCC Rule.1) if PCEF carries out bearing binding; Then PCEF is installed to this Rule in the IP-CAN carrying of identical QCI/ARP parameter according to the qos parameter QCI/ARP among the PCC Rule, but PCEF can not use the filter of such Rule and QoS to generate TFT and the QoS that carries; If the qos parameter of PCC Rule does not carry QCI/ARP, then PCEF can think that failure is installed perhaps will be bundled in this Rule in default bearer or the entire I P-CAN session.2) if PCRF carries out bearing binding, then PCEF directly according to the indication of PCRF, is installed to Rule in the corresponding carrying, but PCEF can not use the filter of such Rule and QoS to generate TFT and the QoS that carries.

The PCC rule that is used to carry control can only be installed in a carrying; The PCC rule that is used for professional control can be only to be installed in a carrying, also can be mounted in interior all carryings of IP-CAN session.In a carrying, must bind the PCC Rule that is useful on bearing binding, the PCC Rule that is used for professional control is optional.Through being used to carry the PCC rule and the regular division of the PCC that is used for professional control of control, the typical application scene is the control and the application scenarios that separates based on the business datum current control that can realize based on carrying, but is not limited only to this.

For example, according to existing protocol, each carries and can only carry 16 filter at most, and this just means that the filter that is tied to all the PCC Rule in each carrying at most also can only be 16.But in practical application,, than the filter definition of TFT more carefully or thicker, promptly differ corresponding one by one surely possibly with the filter of TFT based on the definition of the rule of Business Stream.At this moment, can be used for the PCC rule and the PCC rule that is used for bearing binding of professional control, realize the restriction that do not receive each to carry 16 filter, realize than the filter definition of TFT more carefully or thicker control through definition.
