Implementation strategy of the present invention and the method embodiment one that charges and control; With reference to figure 2, comprising:

A1, PCRF obtain the customer position information of offering on the PCEF.

In embodiments of the present invention, customer position information mainly is meant user's more specific location information.In different access network technologies; The customer position information of definition possibly be different, in this article, and mainly with GPRS (General Packet Radio Service; Be called for short GPRS) network and micro-wave access global inter communication (Worldwide Interoperability for Microwave Access; Abbreviation WiMAX) network is that example describes, but understandable, and the embodiment of the invention is suitable for other access network technologies too.

In GPRS network, the customer position information below having defined:

Tracking Area Identifier (RAI): by Global Mobile Country Code (Mobile Country Code; Abbreviation MCC), mobile service network sign indicating number (Mobile Network Code; Abbreviation MNC), location area code (Location Area Code; Be called for short LAC) and Routing Area sign indicating number (Route Area Code is called for short RAC) composition, be used for identifying uniquely the Routing Area of forming by one or more sub-districts with identical routing iinformation.

Cell Global Identity (CGI): being made up of MCC, MNC, LAC and cell ID (Cell Identity is called for short CI), is a sub-district unique identification in the world.

Coverage sign (SAI): form by MCC, MNC, LAC and service region code (Service Area Code is called for short SAC), be used for identifying uniquely the service area of the one or more sub-districts composition that is positioned at the same position district.

In the WiMAX network, the customer position information of definition comprises: WiMAX cell information etc.

In embodiments of the present invention; PCEF can be an active report of user positional information; For example; PCEF can receive IP be communicated with access network (IP Connectivity Access Network is called for short IP-CAN) session to set up request message after direct report of user positional information, also can be to carry out reporting of customer position information according to the reporting position indication of PCRF.Wherein, the reporting position indication specifically can be to comprise the tabulation of the trigger event of customer position information change events.

PCEF according to the reporting position of PCRF indication report of user positional information can be: PCEF detects the customer position information change events whether indication in the trigger event tabulation takes place, if then report the customer position information after the variation.Below provide several kinds of concrete implementation methods:

The network element of method a, Access Network reports detected customer position information change events to PCEF, and the customer position information after changing; PCEF judges whether said customer position information change events belongs to the customer position information change events of indication in the trigger event tabulation, if then report the customer position information after the said variation.

Method b, the network element of Access Network regularly reports active user's positional information to PCEF; If the type of this customer position information belongs to the type of the corresponding customer position information of the customer position information change events of indication in the trigger event tabulation; PCEF compares said active user's positional information and the customer position information that write down; If both are different, then report said active user's positional information.

Method c, detect when the customer position information change events takes place the customer position information of the network element of Access Network after PCEF reports variation; After PCEF receives customer position information; Directly confirm to take place the customer location change events; If the type of this customer position information belongs to the type of the corresponding customer position information of the customer position information change events of indication in the trigger event tabulation, then report the customer position information that is received.

In embodiments of the present invention; PCEF according to the reporting position of PCRF indication report of user positional information also can be: PCEF judge whether to PCRF reported with the trigger event tabulation in the corresponding customer position information of customer position information change events of indication; If judged result then reports said customer position information for not.

In embodiments of the present invention, PCEF report of user positional information specifically can realize through reporting credit control request (Credit-Control-Request the is called for short CCR) message of carrying customer position information.With the GPRS network is example, and optional a kind of implementation is to comprise that in CCR message property value is that 3GPP customer position information (3GPP-User-Location-Info) property value of CGI/SAI information is right, and/or property value is that the RAI property value of RAI information is right.

A2, confirm user's PCC rule, and send said PCC rule according to the customer position information that is obtained.

The customer position information that the PCRF basis is obtained, and can combine information such as user contracting data, carrier policy to confirm user's PCC rule; If do not send the PCC rule, or the PCC that generates rule is different with the PCC rule that sends to PCEF, then send the PCC rule that is generated to PCEF to PCEF.

PCRF can also be according to the customer position information that obtains, and can combine information such as user contracting data, carrier policy to confirm user's customer position information change events, generates corresponding reporting position indication; If do not send the reporting position indication to PCEF, or the reporting position that generates indication is different with the reporting position indication that sends to PCEF, then sends the reporting position indication that is generated to PCEF; Wherein, The reporting position indication specifically can be to comprise the tabulation of the trigger event of customer position information change events; After PCEF receives the trigger event tabulation of PCRF transmission; Detect the customer position information change events whether indication in the trigger event tabulation takes place, if then report the customer position information after the variation.

In embodiments of the present invention, PCRF can pass through Credit Control Answer (Credit-Control-Answer is called for short CCA) message or authorization requests (Re-Auth-Request is called for short RAR) message regular and reporting position indication to PCEF transmission PCC again.

When the reporting position indication was the trigger event tabulation, PCRF can realize the transmission that trigger event is tabulated through in CCA message or RAR message, carrying the trigger event tabulation.Provide two kinds of concrete implementation methods of sending the trigger event tabulation through CCA message or RAR message below:

CCA message or RAR message that trigger event (Event-Trigger) attribute is carried in method A, transmission comprise one or more change in location incidents corresponding to the unique user positional information in the property value of said Event-Trigger attribute.

The Event-Trigger attribute is the data object of enumeration type, 0～10 property value has been made definition in the 7.0.0 version of 3GPP TS29.212; In embodiments of the present invention, can on the basis of defined attribute value, expand, increase property value corresponding to the change in location incident of unique user positional information to the Event-Trigger attribute.

Based on above-mentioned definition, through in the Event-Trigger attribute of CCA message or RAR message, comprising the property value corresponding to the corresponding change in location incident of unique user positional information, realization comprises the transmission of the trigger event tabulation of customer position information change events.

After PCEF receives CCA message or RAR message, if detect the customer position information change events of indicating in the Event-Trigger attribute in the above-mentioned message, the then customer position information after PCRF reports variation.

After PCEF receives CCA message or RAR message; Also can judge whether to report the corresponding customer position information of customer position information change events of indicating in the Event-Trigger attribute in the message to PCRF; If judged result then reports said customer position information to PCRF for not.

For helping to understand, be example to adopt GPRS to insert below, provide the instantiation of method A:

In this example, increase by two property values for the Event-Trigger attribute: one is RAI_CHANGE (x1), is used to represent the RAI change events, and another is CGI_SAI_CHANGE (x2), is used to represent the CGI/SAI change events; Wherein, x1 is different with x2, and with the Event-Trigger attribute in the property value that defined different.

According to above-mentioned definition, when in PCRF is sending to the Event-Trigger attribute of CCA message or RAR message of PCEF, comprising property value RAI_CHANGE (x1), expression PCRF requires PCEF to report the variation of RAI; When comprising property value CGI_SAI_CHANGE (x2) in the Event-Trigger attribute, expression PCRF requires PCEF to report the variation of CGI/SAI.

CCA message or RAR message that trigger event (Event-Trigger) attribute is carried in method B, transmission comprise the change in location incident corresponding to whole customer position informations in the property value of said Event-Trigger attribute.

In embodiments of the present invention, can on the basis of defined attribute value, expand, increase by one corresponding to whole property values of the change in location incident of customer position informations to the Event-Trigger attribute.

Based on above-mentioned definition, through in the Event-Trigger attribute of CCA message or RAR message, comprising this property value corresponding to the change in location incident of whole customer position informations, realization comprises the transmission of the trigger event tabulation of customer position information change events.

After PCEF receives CCA message or RAR message, if detect any customer position information change events, the then customer position information after PCRF reports variation.

After PCEF receives CCA message or RAR message, also can judge whether to report all customer position informations to PCRF,, then report this customer position information to PCRF if there is certain customer position information not report.

Be example still below, provide the instantiation of method B to adopt GPRS to insert:

In this example, for the Event-Trigger attribute increases property value a: LOCATION_CHANGE (x), be used to represent the customer position information change events; Wherein, the property value that has defined in x and the Event-Trigger attribute is different.

According to above-mentioned definition, when in PCRF is sending to the Event-Trigger attribute of CCA message or RAR message of PCEF, comprising property value LOCATION_CHANGE (x), expression PCRF requires PCEF to report all customer position informations to change.

Cross operator switches or spans into the ability that technological switching possibly cause PCEF to obtain customer position information and changes; Therefore; In embodiments of the present invention; The position acquisition capability information that PCRF can also report according to PCEF, and can combine information such as customer position information, user contracting data, carrier policy to confirm user's customer position information change events, generate corresponding reporting position indication; If do not send the reporting position indication to PCEF, or the reporting position that generates indication is different with the reporting position indication that sends to PCEF, then sends the reporting position indication that is generated to PCEF.In embodiments of the present invention, described position acquisition capability mainly is meant whether have the ability of obtaining customer position information.

In addition; PCRF can also be when the position of PCEF acquisition capability information changes; The position acquisition capability information that reports according to PCEF, and can combine information such as customer position information, user contracting data, carrier policy to carry out the PCC decision-making again, confirm the PCC rule that the user is current.

In embodiments of the present invention, PCEF can carry position acquisition capability information in sending to the CCR message of PCRF, thereby realizes reporting of position acquisition capability, and this process can be set up in the IP-CAN session, and/or takes place when revising.Provide several kinds of concrete implementation methods below through CCR information reporting position acquisition capability information:

Method one, in CCR message, to carry one or more position acquisition capability property values corresponding to the unique user positional information right, and the right property value of this property value representes whether have the ability of obtaining the relative users positional information.

RAI_REPORT (1), expression has the ability of obtaining RAI information.

Another is the corresponding position acquisition capability attribute Location-Report-Ability of CGI/SAI, is these two property values below attribute definition:

NONE (0), expression does not have the ability of obtaining CGI/SAI information.

LOCATION_REPORT (1), expression has the ability of obtaining CGI/SAI information.

According to above-mentioned definition, when PCEF need report when not having the ability of obtaining RAI information to PCRF, comprise that in sending to the CCR message of PCRF property value is that the RAI-Report-Ability property value of NONE (0) is right; When PCEF need report when having the ability of obtaining RAI information to PCRF, comprise that in sending to the CCR message of PCRF property value is that the RAI-Report-Ability property value of RAI_REPORT (1) is right.

Equally, when PCEF need report when not having the ability of obtaining CGI/SAI information to PCRF, comprise that in sending to the CCR message of PCRF property value is that the Location-Report-Ability property value of NONE (0) is right; When PCEF need report when having the ability of obtaining CGI/SAI information to PCRF, comprise that in sending to the CCR message of PCRF property value is that the Location-Report-Ability property value of LOCATION_REPORT (1) is right.

Method two, in CCR message, carry corresponding to the position acquisition capability property value of a plurality of customer position informations rightly, the right property value of this property value representes whether to have the partly or entirely ability of said a plurality of customer position informations of obtaining.

Can expand CCR message; Increase a position acquisition capability attribute, and represent whether to have the property value of the ability of obtaining part or all of these a plurality of customer position informations for the position acquisition capability attribute definition that increases corresponding to a plurality of customer position informations.

Be example still, provide an instantiation of method two to adopt GPRS to insert:

In this example, for CCR message increases position acquisition capability attribute a: Location-Report-Ability, be these four property values below attribute definition:

NONE (0), expression does not have the ability of obtaining customer position information.

RAI_REPORT (1), expression has the ability of obtaining RAI information.

CGI_SAI_REPORT (2), expression has the ability of obtaining CGI/SAI information.

RAI_CGI_SAI_REPORT (3), expression has the ability of obtaining RAI and CGI/SAI information.

According to above-mentioned definition, when PCEF need report when not having the ability of obtaining customer position information to PCRF, comprise that in sending to the CCR message of PCRF property value is that the Location-Report-Ability property value of NONE (0) is right; When PCEF need report when having the ability of obtaining RAI information to PCRF, comprise that in sending to the CCR message of PCRF property value is that the Location-Report-Ability property value of RAI REPORT (1) is right; When PCEF need report when having the ability of obtaining CGI/SAI information to PCRF, comprise that in sending to the CCR message of PCRF property value is that the Location-Report-Ability property value of CGI_SAI_REPORT (2) is right; When PCEF need report when having the ability of obtaining RAI and CGI/SAI information to PCRF, comprise that in sending to the CCR message of PCRF property value is that the Location-Report-Ability property value of RAI_CGI_SAI_REPORT (3) is right.

Method three, in CCR message, carry corresponding to the position acquisition capability property value of whole customer position informations rightly, the right property value of this property value representes whether have the ability of obtaining whole customer position informations.

Can expand CCR message, increase by one corresponding to whole position acquisition capability attributes of customer position informations, and the property value of representing whether to have the ability of obtaining whole customer position informations for the position acquisition capability attribute definition that increases.

To adopt GPRS to insert is example, provides an instantiation of method three:

In this example, for CCR message increases position acquisition capability attribute a: Location-Report-Ability, be these two property values below attribute definition:

LOCATION_REPORT (1), expression has the ability of obtaining whole customer position informations.

According to above-mentioned definition, when PCEF need report when not having the ability of obtaining customer position information to PCRF, comprise that in sending to the CCR message of PCRF property value is that the Location-Report-Ability property value of NONE (0) is right; When PCEF need report when having the ability of obtaining whole customer position informations to PCRF, comprise that in sending to the CCR message of PCRF property value is that the Location-Report-Ability property value of LOCATION_REPORT (1) is right.

Method four, in CCR message, to carry the customer position information property value right, and the right property value of this property value is the particular value of representing not have the ability of obtaining the relative users positional information, or property value is that empty customer position information property value is right.

In embodiments of the present invention, can expand the property value that the definition expression does not have the ability of obtaining the relative users positional information to the customer position information attribute.

To adopt GPRS to insert is example, provides an instantiation of method four:

In this example, the right property value of definition 3GPP-User-Location-Info property value is 1 entirely, and perhaps the established part of property value is 1, and when perhaps property value was empty, expression did not have the ability of obtaining CGI/SAI information; The right property value of definition RAI property value is 1 entirely, and perhaps the established part of property value is 1, and when perhaps property value was empty, expression did not have the ability of obtaining RAI information.

According to above-mentioned definition; When PCEF need report when not having the ability of obtaining CGI/SAI information to PCRF; Comprise that in sending to the CCR message of PCRF property value is 1 entirely, perhaps the established part of property value is 1, and perhaps property value is that empty 3GPP-User-Location-Info property value is right; When PCEF need report when not having the ability of obtaining RAI information to PCRF, in sending to the CCR message of PCRF, carrying property value is 1 entirely, and perhaps the established part of property value is 1, and perhaps property value is that empty RAI property value is right.
