Below in conjunction with accompanying drawing and preferred embodiment technical scheme of the present invention is described and explains in detail so that this technical scheme can be well understood to and can be implemented, but illustrated embodiment is all not as a limitation of the invention.
The method of PCC strategy is formulated in realization provided by the invention, relates to strategy and charging execution function entity PCEF, "Policy and Charging Rules Function entity PCRF and user-subscribed database SPR, and this method comprises:
(1) in SPR, preserves the location-based CAMEL-Subscription-Information of user equipment (UE) signing service in advance;
For example, preserve the location-based CAMEL-Subscription-Information of the following different signing service of UE in SPR, as shown in table 1, wherein CAMEL-Subscription-Information comprises positional information, QoS information, charge information etc.
Table 1
When the A that commences business (Service A), if UE current position information (such as time zone, sub-district or tracking area) is Location 1, its current QoS information (comprise medium type, guarantee bandwidth, transfer level etc.) is QoS Profile 1, then corresponding charge information (for example rate group rate group etc.) is Charging Info 1, if the UE current position information is Location 2 or Location 3, then QoS information is QoS Profile 2, and charge information is Charging Info 2.Similarly, when carrying out Service B corresponding to the CAMEL-Subscription-Information of UE diverse location.
In above positional information, " sub-district " (or " route district ") is the location definition in universal mobile telecommunications system (UMTS, the Universal Mobile Telecommunication System) system; " tracking area " is the location definition among the grouping system EPS of evolution; " time zone " then is the location definition that all has at various mobile communcations systems.
More than the UE different business in SPR, preserved based on the CAMEL-Subscription-Information of diverse location, use in the time of need formulating professional PCC strategy according to positional information for PCRF.
Notice that the CAMEL-Subscription-Information of statement only is its a kind of form in the table 1, in fact, CAMEL-Subscription-Information is not this this a kind of form only, also has many other forms.For example, charge information wherein can also that is to say that charge information not only depends on positional information again at the further refinement of QoS information, also depends on QoS information simultaneously, or the like.
(2) PCRF chooses corresponding CAMEL-Subscription-Information according to the current position of UE in business procedure, and formulates the PCC strategy or determine whether to upgrade the PCC strategy according to the CAMEL-Subscription-Information of choosing, and gives PCEF with the PCC policy distribution of formulating or upgrading.
Divide following three kinds of application scenarioss:
A, when UE initiates one when professional, the position that PCRF is current according to UE obtains corresponding CAMEL-Subscription-Information from the location-based CAMEL-Subscription-Information of this business, and formulates the PCC policy distribution according to the CAMEL-Subscription-Information that obtains and give PCEF.
PCRF can should the location-based CAMEL-Subscription-Information of business to UE to the SPR acquisition request, and is stored in this locality, therefrom obtains the position corresponding CAMEL-Subscription-Information (comprise charge information etc.) current with UE; Perhaps, according to the current position of UE to the SPR acquisition request CAMEL-Subscription-Information corresponding (comprising charge information etc.) with this position.
Receive the CAMEL-Subscription-Information request message of PCRF as SPR, according to the UE information of carrying in the message (such as the number of UE etc.) and business information (for example service identification of professional A) inquire that UE should business based on the relevant information in the CAMEL-Subscription-Information of diverse location, and return the CAMEL-Subscription-Information response message to PCRF, contain the CAMEL-Subscription-Information that UE should business in the message based on diverse location, as shown in table 2.
Table 2
| Positional information | QoS information | Charge information | Out of Memory |
| ??Location?1 | ??QoS?Profile?1 | ??Charging?Info?1 | ??...... |
| ??Location?2 | ??QoS?Profile?2 | ??Charging?Info?2 | ...... |
| ??Location?3 | ??QoS?Profile?2 | ??Charging?Info?2 | ...... |
After PCRF receives this response message, preserve UE should business based on corresponding subscription data (table 2) in the CAMEL-Subscription-Information of diverse location, when carrying out this business, according to the corresponding CAMEL-Subscription-Information of the current choice of location of UE (comprising charge information etc.), and according to the CAMEL-Subscription-Information formulation PCC strategy of selecting.
Perhaps, receive the CAMEL-Subscription-Information request message of PCRF as SPR, information (such as Location1) according to the UE information of carrying in the message and business information (such as service identification) and UE current location, inquire the CAMEL-Subscription-Information of this business at the UE current location, and return the CAMEL-Subscription-Information response message to UE, carry the CAMEL-Subscription-Information of this business in the message at the UE current location, as shown in table 3.
Table 3
| QoS information | Charge information | Out of Memory |
| ??QoS?Profile?1 | ??Charging?Info?1 | ??...... |
After PCRF receives this response message, preserve the CAMEL-Subscription-Information at the UE current location (comprising charge information etc.) wherein, and formulate the PCC strategy according to this CAMEL-Subscription-Information.
Perhaps, SPR receives the CAMEL-Subscription-Information request message of PCRF, information (such as Location1) and the current QoS information (such as QoS Profile 1) of UE according to the UE information of carrying in the message and business information (such as service identification), UE current location, inquire the charge information of this business at UE current location, Qos, and return the CAMEL-Subscription-Information response message to UE, carry the charge information of this business in the message at UE current location, Qos.
B, the CAMEL-Subscription-Information that detects UE as SPR in business procedure change, and then notify the location-based CAMEL-Subscription-Information that PCRF should business to upgrade; PCRF obtains the CAMEL-Subscription-Information corresponding with this position according to the current position of UE in this business, and upgrades the PCC strategy when whether checking needs according to the CAMEL-Subscription-Information that obtains, and needs then to give PCEF with the PCC policy distribution that upgrades.
The CAMEL-Subscription-Information of the detected UE of SPR changes, such as the signatory positional information change of UE, or the signatory changes such as charge information corresponding with positional information of UE.
After PCRF receives the notice (promptly upgrading CAMEL-Subscription-Information request or indication) of SPR, the position current according to UE, should business obtain corresponding CAMEL-Subscription-Information (comprising charge information) from the UE of local storage update, or obtain corresponding CAMEL-Subscription-Information (i.e. table 3) from SPR based on the CAMEL-Subscription-Information (i.e. table 2) of diverse location.
C, change, updated information is informed PCRF when PCEF detects the current information of UE in business procedure; PCRF updated information in view of the above obtains the CAMEL-Subscription-Information of renewal, and checks according to the CAMEL-Subscription-Information that upgrades whether needs upgrade the PCC strategy, needs then to give PCEF with the PCC policy distribution that upgrades.
The current information of the detected UE of PCEF changes, such as the UE current position information changes.If the CAMEL-Subscription-Information that PCRF preserves according to this locality is enough to judge corresponding CAMEL-Subscription-Information (comprising charge information etc.) and needs to upgrade, and can get access to the CAMEL-Subscription-Information of renewal from this locality, then obtain CAMEL-Subscription-Information corresponding to the position of this change from this locality; Whether needs upgrade if the CAMEL-Subscription-Information that PCRF preserves according to this locality is not enough to judge corresponding CAMEL-Subscription-Information, then ask SPR to obtain CAMEL-Subscription-Information (comprising charge information etc.) under the position that UE changes again.
The present invention is directed to said method, propose the corresponding system that formulates service charging policy, comprise the strategy and charging execution function entity PCEF, "Policy and Charging Rules Function entity PCRF and the user-subscribed database SPR that connect successively, wherein:
PCEF is used for according to the PCC strategy that receives from the PCRF statistics of chargeing; Report the UE service related information to PCRF;
