Description

Policy control method, entity and system

Technical field

The present invention relates to communication technical field, particularly relate to a kind of policy control method, entity and system.

Background technology

Along with the development of the communication technology, the strategy of G mobile communication (3rd-generation, 3G) network and charging control (PolicyandChargingControl, PCC) system obtain and use widely.In order to promote the reliability of PCC system, in 3G network, usually can configure two or more "Policy and Charging Rules Function (PolicyandChargingRuleFunction, PCRF) entity, carrying out networking that is active and standby or load balancing mode.When one of them PCRF entity breaks down, business can be taken over by other PCRF entity, and business can be continued.

At present, the classical group net mode of PCC system can be divided into two kinds: first, Diameter route agent (DiameterRoutingAgent is there is in PCC system, DRA), i.e. DRA networking, in DRA networking, network element comprises general packet radio service (GeneralPacketRadioService, GPRS) gateway supports node (GatewayGPRSSupportNode, GGSN), DRA, with PCRF entity, wherein the quantity of PCRF entity decides according to the networks trategy of reality, at this, be only primary PCRF entity with PCRF1 entity, PCRF2 entity is PCRF entity for subsequent use is that example illustrates.

When user reaches the standard grade, after GGSN sets up session by DRA to the application of PCRF1 entity, receive the policy control information of PCRF1 entity transmission and carry out policy control according to this policy control information; When the use traffic of GGSN monitor user ' and duration exceed the policy control threshold value in policy control information, by DRA to the new policy control information of PCRF1 entity application, after GGSN receives new policy control information, the policy control information utilizing this new carries out policy control; When user offline, GGSN sends user offline request by DRA to PCRF1 entity, after GGSN receives the response of PCRF1 entity, and GGSN releasing session.

But after PCRF1 entity breaks down, DRA automatically switches to the above-mentioned business of PCRF2 entity handles, the route corresponding relation simultaneously between recording conversation mark and PCRF2 entity.When PCRF2 entity receives credit control request (CreditControlRequest, CCR) after, find that the session identification received does not exist, return the Credit Control Answer (CreditControlAnswer of failure, CCA) to DRA, this CCA message is turned back to GGSN by DRA, and after GGSN receives the response message of failure, force users rolls off the production line.

There is not Diameter route agent in the second, PCC system, namely without DRA networking, without in DRA networking, comprise GGSN and PCRF entity.Its workflow is substantially identical with DRA networking, has just lacked the forwarding capability of DRA.

At present, no matter PCC system adopts DRA networking, or DRA networking, when PCRF1 entity breaks down, when the customer service of this PCRF1 entity carrying switches to PCRF2 entity, customer service can be interrupted, not only reduce PCC system reliability, go back the complexity that adding users uses.

Embodiment

For making the object of the embodiment of the present invention, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.

The invention discloses a kind of policy control method, PCEF entity, PCRF entity and system, when detecting strategy and the first link failure between charge execution function PCEF entity and the first "Policy and Charging Rules Function PCRF entity, PCEF entity is switched to the second link between the 2nd PCRF entity; PCEF entity sends the first diameter credit control update request CCR-U by the second chain road direction the 2nd PCRF entity, user conversation mark is carried in one CCR-U, and user's extend information, described user's extend information is used for, when described 2nd PCRF entity judges that described user conversation mark does not exist, setting up session according to described user's extend information and PCEF entity; After the 2nd PCRF entity and PCEF entity set up session, receive the first diameter credit control renewal response CCA-U that the 2nd PCRF sends, a CCA-U carries the second policy control information; Carry out policy control according to described second policy control information, thus under achieving and nonserviceabling, by adding the method for user's extend information, achieving and continuing to carry out policy control to the business of user, also improving the reliability of this system.

The Organization Chart of the PCC system that Fig. 1 provides for the embodiment of the present invention one.As shown in the figure, this PCC system is without DRA networking mode.The embodiment of the present invention specifically comprises: strategy and charge execution function (PolicyandChargingEnforcementFunction, PCEF) entity 11, a PCRF entity 12 and a PCRF entity 13.Wherein, PCEF entity 11 can be positioned at the GGSN gateway of GPRS, also can be positioned at WLAN (WirelessLocalAreaNetworks, WLAN), can also independently dispose.The function of PCEF entity 11 mainly comprises the detection of business data flow, strategy execution and the billing function based on stream.

In this system, the operation principle of each several part is divided into three processes:

The first, when user reaches the standard grade, PCEF entity 11 initiation session activation process.

First, PCEF entity 11 sends initial credit control request (CreditControlRequest-Initial to a PCRF entity 12, CCR-I) ask, session is set up in application, carries the key message of session identification, user ID in this solicited message.

Again, a PCRF entity 12 sets up session after receiving CCR-I request, returns the response message of initial credit control response (CreditControlAnswer-Initial, CCR-I) to PCEF entity 11.The first policy control information issued is carried in this response message.Wherein, the flow allowing user to use in the first policy control information, can be comprised, or the policy control threshold value of the user's online hours allowed.

Finally, PCEF entity 11 carries out policy control according to the first policy control information received.

The second, when use traffic and the duration of PCEF entity 11 monitor user ', during the policy control threshold value issued before exceeding, initiate quota more new technological process, namely adopt the policy control method that any one embodiment of the following embodiment of the present invention three to five provides.

3rd, when user offline, PCEF entity 11 initiates to roll off the production line flow process.This part is common technology of the prior art, here no longer describes in detail.

The Organization Chart of the PCC system that Fig. 2 provides for the embodiment of the present invention two.As shown in the figure, this PCC system is for there being DRA networking mode.The embodiment of the present invention specifically comprises: PCEF entity 11, DRA14, a PCRF entity 12 and a PCRF entity 13.

First, PCEF entity 11 sends initial credit control request (CreditControlRequest-Initial, CCR-I) request to DRA14, and session is set up in application, carries the key message of session identification, user ID in this solicited message.

Then, message is transmitted to a PCRF entity 12 according to the strategy of polling or priority by DRA14, preserves a PCRF entity 12 corresponding to session identification simultaneously.

Again, a PCRF entity 12 sets up session after receiving CCR-I request, returns the response message of initial credit control response (CreditControlAnswer-Initial, CCR-I) to DRA14.The first policy control information issued is carried in this response message.Wherein, the flow allowing user to use in policy control information, can be comprised, or the policy control threshold value of the user's online hours allowed.

Finally, CCA-I message is transmitted to PCEF entity 11 by DRA14.PCEF entity 11 carries out policy control according to the content received.

The second, when use traffic and the duration of PCEF entity 11 monitor user ', during the policy control threshold value issued before exceeding, initiate quota more new technological process, namely adopt the policy control method that any one embodiment of the following embodiment of the present invention six to eight provides.

The flow chart of the policy control method that Fig. 3 provides for the embodiment of the present invention three.In the process that the method upgrades for the quota of PCC system.As shown in the figure, the present embodiment specifically comprises the following steps:

Step 310, when PCEF entity detection goes out the first link failure between PCEF entity and the first "Policy and Charging Rules Function PCRF entity, will be switched to the second link between PCEF entity and the 2nd PCRF entity.

Particularly, a PCRF entity is primary PCRF entity, and the 2nd PCRF entity is PCRF entity for subsequent use, and primary PCRF entity and PCRF entity for subsequent use lead a standby work pattern with one.During the first link failure between PCEF entity and primary PCRF entity, at this moment just need to enable the business that PCRF entity for subsequent use carries to carry primary PCRF entity, this business can be continued.

Or a PCRF entity and the 2nd PCRF entity work in the mode of load sharing simultaneously.One PCRF entity may be the more PCRF entity of duty ratio, also may be the less PCRF entity of duty ratio, but during the first link failure between PCEF entity and a PCRF entity, at this moment the business needing the 2nd PCRF entity on the second link to carry a PCRF entity to carry, makes this business to continue.

In addition, the policy control threshold value in the first policy control information for allowing the threshold value of the flow of user's use, or can allow the threshold value of user's online hours.State value of reaching the standard grade is the flow value that user uses, or user's online hours value.When PCEF entity detection goes out the state value of reaching the standard grade of user more than the policy control threshold value in the first policy control information, PCEF entity initiates quota more new technological process.

Alternatively, policy control threshold value in the first policy control information that the state value of reaching the standard grade going out user when PCEF entity detection issues more than a PCRF entity, and when detecting the first link failure between PCEF entity and a PCRF entity, PCEF entity sets up the second link between the 2nd PCRF entity.

Step 320, PCEF entity sends the first diameter credit control update request (CreditControlRequest-Update, CCR-U) by the second chain road direction the 2nd PCRF entity, carries user conversation mark in a CCR-U, and user's extend information.This user's extend information is used for, when described 2nd PCRF entity judges that described user conversation mark does not exist, setting up session according to described user's extend information and PCEF entity.Wherein, user's extend information is session multidate information; Agreement (InternetProtocol, the IP) address information that session multidate information comprises user totem information, interconnects between access style information and user network.

Particularly, if the first link does not break down, PCEF entity should send a CCR-U, a CCR-U to a PCRF entity and only include user conversation mark, this user conversation mark is user when reaching the standard grade, and PCEF entity partitioning is to user session identification.Meanwhile, on user in line process, a PCRF entity establishes session with PCEF entity according to user conversation mark and user totem information.Now, if PCEF entity detection goes out the state value of reaching the standard grade of user more than after the policy control threshold value in the first policy control information, need to obtain new policy control information from a PCRF entity, because PCEF entity the with one PCRF entity establishes session, and a PCRF entity has saved all information with this user, so when PCEF entity is again with a PCRF entity communication, only need user conversation to identify.

But, when after PCEF entity detection to the first link failure, then when sending the first letter CCR-U to the 2nd PCRF entity, automatically can add user's extend information in a CCR-U.Because on user in line process, PCEF entity establishes session with a PCRF entity, do not set up session with the 2nd PCRF entity, so the 2nd PCRF entity does not exist any information of this user.When PCEF entity and the 2nd PCRF entity communication, if user conversation mark in a CCR-U, and user's extend information, 2nd PCRF entity is inquired about and is identified relevant information record less than to this user conversation in the stored data base of self, then according to user's extend information automatic Reconstruction session information.Its process setting up session information is as follows: be kept in the 2nd PCRF entity by the user totem information in user's extend information, access style information and IP address information etc., rebuilding session information is process in the inside of the 2nd PCRF, and then returns the second policy control information to PCEF entity.This second policy control information returned with the first policy control information function logic is identical, just along with user is to the use procedure of network, partial parameters has renewal.

Step 330, after the 2nd PCRF entity and PCEF entity set up session, PCEF entity receives the first diameter credit control renewal response (CreditControlAnswer-Update, CCA-U) that the 2nd PCRF sends.Wherein, a CCA-U carries the second policy control information;

Step 340, PCEF entity carries out policy control according to the second policy control information to user.

Therefore, the policy control method that the embodiment of the present invention provides, when PCEF entity detection goes out the state value of reaching the standard grade of user more than the policy control threshold value in the first policy control information, and during the first link failure between PCEF entity and the first "Policy and Charging Rules Function PCRF entity, the second link between PCEF entity and the 2nd PCRF entity will be switched to, and the first diameter credit control update request of carrying user's extend information is sent by the second chain road direction the 2nd PCRF entity, after the 2nd PCRF entity and PCEF entity set up session, the first diameter credit control receiving the second policy control information carried that the 2nd PCRF sends upgrades response, and according to the second policy control information, policy control is carried out to user, thus under achieving and nonserviceabling, by adding the method for user's extend information, the business achieving user continues to carry out, also improve the reliability of policy control.

The flow chart of the policy control method that Fig. 4 provides for the embodiment of the present invention four.In the process that the method upgrades for the quota of PCC system.As shown in the figure, the present embodiment specifically comprises the following steps:

Step 410, PCRF entity receives the CCR-U that PCEF entity sends, and carries user conversation mark in a CCR-U, and user's extend information.Wherein, user's extend information is session multidate information; The Protocol IP address information that session multidate information comprises user totem information, interconnects between access style information and user network.

Particularly, PCRF entity can be primary PCRF entity, also can be PCRF entity for subsequent use, also can for the arbitrary PCRF entity worked in the mode of load sharing simultaneously.

Step 420, carries out judging self whether to there is user conversation mark according to user conversation mark.

Particularly, the 2nd PCRF entity is inquired about and is identified relevant information record to this user conversation in the stored data base of self, when inquiring about not then, then thinks that this user conversation mark does not exist.

Step 430, when user conversation mark does not exist, session is set up according to user's extend information and PCEF entity, and send the first diameter credit control renewal response CCA-U to PCEF entity, one CCA-U carries the second policy control information, carries out policy control in order to PCEF entity according to the second policy control information to user.

Therefore, the policy control method that the embodiment of the present invention provides, the user conversation that carries that PCRF entity receives the transmission of PCEF entity identifies, and a CCR-U of user's extend information, carry out judging self whether to there is user conversation mark according to user conversation mark, when user conversation mark does not exist, session is set up according to user's extend information and PCEF entity, and send the first diameter credit control renewal response CCA-U to PCEF entity, one CCA-U carries the second policy control information, according to the second policy control information, policy control is carried out to user in order to PCEF entity, thus under achieving and nonserviceabling, user's extend information is utilized to re-establish the session with PCEF entity, achieve and continue to carry out policy control to the business of user, also improve the reliability of policy control.

The flow chart of the policy control method that Fig. 5 provides for the embodiment of the present invention five.In the process that the method upgrades for the quota of PCC system.As shown in the figure, the present embodiment specifically comprises the following steps:

Step 510, when PCEF entity detection goes out the state value of reaching the standard grade of user more than the policy control threshold value in the first policy control information, route agent DRA receives the 2nd CCR-U that PCEF entity sends, and carries user conversation mark in the 2nd CCR-U.

Particularly, the threshold value of the flow that the policy control threshold value in the first policy control information can use for permission user, or the threshold value of the user's online hours allowed.State value of reaching the standard grade is the flow value that user uses, or user's online hours value.

User conversation mark is that user reaches the standard grade is that PCEF entity partitioning is to the session identification of user.When PCEF entity detection goes out the state value of reaching the standard grade of user more than the policy control threshold value in the first policy control information, PCEF entity initiates quota more new technological process, and sends the 2nd CCR-U by route agent DRA, carries user conversation mark in the 2nd CCR-U.

Step 520, after DRA receives the 2nd CCR-U, and when detecting the first link failure between DRA and a PCRF entity, DRA sets up the second link between the 2nd PCRF entity.Wherein, a PCRF entity is primary PCRF entity, and the 2nd PCRF entity is PCRF entity for subsequent use, and primary PCRF entity and PCRF entity for subsequent use lead a standby work pattern with one.Or a PCRF entity and the 2nd PCRF entity work in the mode of load sharing simultaneously.

Particularly, a PCRF entity is primary PCRF entity, and the 2nd PCRF entity is PCRF entity for subsequent use, and primary PCRF entity and PCRF entity for subsequent use lead a standby work pattern with one.During the first link failure between DRA and primary PCRF entity, at this moment just need to enable the business that PCRF entity for subsequent use carries to carry primary PCRF entity, this business can be continued.

Or a PCRF entity and the 2nd PCRF entity work in the mode of load sharing simultaneously.One PCRF entity may be the more PCRF entity of duty ratio, also may be the less PCRF entity of duty ratio, but during the first link failure between DRA and a PCRF entity, at this moment the business needing the 2nd PCRF entity on the second link to carry a PCRF entity to carry, makes this business to continue.

Step 530, DRA forwards the 2nd CCR-U by the first chain road direction the 2nd PCRF entity, identifies the user conversation in the 2nd CCR-U in order to the 2nd PCRF entity.

Particularly, user conversation mark is only carried in the 2nd CCR-U.Because PCEF entity is by the 2nd CCR-U sending value DRA, when the first link between DRA and a PCRF entity does not break down, 2nd CCR-U should be transmitted to a PCRF entity by DRA, on user in line process, one PCRF entity establishes session with PCEF entity, and preserves all information of this user.But DRA detects the first link failure between itself and a PCRF entity, then the 2nd CCR-U is transmitted to the 2nd PCRF entity, but the 2nd PCRF entity does not set up session with PCEF entity, does not preserve all information of this user yet.So when the 2nd PCRF entity receives the 2nd CCR-U carrying user conversation mark, the any relevant information identified less than this user conversation is inquired about in the database of self, then think that the 2nd CCR-U is error message, and think that this user conversation mark does not exist.

Step 540, when the 2nd PCRF Entity recognition go out user conversation mark do not exist time, PCEF entity by DRA receive the 2nd PCRF entity send the 2nd CCA-U, the 2nd CCA-U carries user conversation and identifies non-existent information.

Particularly, user conversation identifies non-existent information and illustrates, the 2nd PCRF entity thinks that the 2nd CCR-U that PCEF entity sends is error message.

Step 550, user conversation identifies by PCEF entity, and user's extend information is added in a CCR-U, and forward a CCR-U by DRA to the 2nd PCRF entity, when judging that user conversation mark does not all exist in order to the 2nd PCRF entity, and set up session according to user's extend information and PCEF entity.Wherein, user's extend information is session multidate information; The Protocol IP address information that session multidate information comprises user totem information, interconnects between access style information and user network.

Particularly, if user conversation mark in a CCR-U, and user's extend information, 2nd PCRF entity is inquired about and is identified relevant information record less than to this user conversation in the stored data base of self, then the user totem information in user's extend information, access style information and IP address information etc. are kept in the 2nd PCRF entity, automatic Reconstruction session information, and then return the second policy control information to PCEF entity.This second policy control information returned with the first policy control information function logic is identical, just along with user is to the use procedure of network, partial parameters has renewal.

Step 560, after the 2nd PCRF entity and PCEF entity set up session, the first diameter credit control that PCEF entity receives the 2nd PCRF transmission by DRA upgrades response CCA-U, and a CCA-U carries the second policy control information.

Step 570, carries out policy control according to the second policy control information to user.

Therefore, the policy control method that the embodiment of the present invention provides, when PCEF entity detection goes out the state value of reaching the standard grade of user more than the policy control threshold value in the first policy control information, and DRA is when detecting the first link failure between itself and the first "Policy and Charging Rules Function PCRF entity, the second link between itself and the 2nd PCRF entity will be switched to, and the first diameter credit control update request of carrying user's extend information is sent by the second chain road direction the 2nd PCRF entity, after the 2nd PCRF entity and PCEF entity set up session, the first diameter credit control being received the second policy control information carried that the 2nd PCRF sends by DRA upgrades response, and according to the second policy control information, policy control is carried out to user, thus under achieving and nonserviceabling, by adding the method for user's extend information, the business achieving user continues to carry out, also improve the reliability of policy control.

Step 630, when user conversation mark does not exist, send the 2nd CCA-U by DRA to PCEF entity, the 2nd CCA-U carries user conversation and identifies non-existent information.

Step 640, receives the CCR-U that PCEF entity is forwarded by route agent DRA, and a CCR-U carries user conversation mark, and user's extend information.Wherein, user's extend information is session multidate information; The Protocol IP address information that session multidate information comprises user totem information, interconnects between access style information and user network.

Step 650, when user conversation mark does not exist, session is set up according to user's extend information and PCEF entity, and send the first diameter credit control renewal response CCA-U by DRA to PCEF entity, one CCA-U carries the second policy control information, carries out policy control in order to PCEF entity according to the second policy control information to user.

Particularly, the 2nd PCRF entity is inquired about and is identified relevant information record less than to this user conversation in the stored data base of self, then automatic Reconstruction session information.

Therefore, the policy control method that the embodiment of the present invention provides, the user conversation that carries that PCRF entity receives the transmission of PCEF entity by DRA identifies, and a CCR-U of user's extend information, carry out judging self whether to there is user conversation mark according to user conversation mark, when user conversation mark does not exist, session is set up according to user's extend information and PCEF entity, and send the first diameter credit control renewal response CCA-U by DRA to PCEF entity, one CCA-U carries the second policy control information, according to the second policy control information, policy control is carried out to user in order to PCEF entity, thus under achieving and nonserviceabling, user's extend information is utilized to re-establish the session with PCEF entity, achieve and continue to carry out policy control to the business of user, also improve the reliability of policy control.
