Description

The authorization requests method, system and device

Technical field

The present invention relates to the communications field, in particular to a kind of authorization requests method, system and device.

Background technology

Third generation partner program (3rd Generation Partnership Project, abbreviate 3GPP as) grouping system (the Evolved Packet System of evolution, abbreviate EPS as) by Universal Terrestrial Radio Access Network (the Evolved Universal Terrestrial RadioAccess Network of evolution, abbreviate E-UTRAN as), mobile management unit (MobilityManagement Entity, abbreviate MME as), gateway (Serving Gateway, abbreviate S-GW as), grouped data network gateway (Packet Data Network Gateway, abbreviate P-GW as), home subscriber server (Home Subscriber Server, abbreviate HSS as) form, Fig. 1 is the configuration diagram that inserts EPS according to the HeNB under the non-roaming scene of correlation technique, Fig. 2 is the configuration diagram that inserts EPS according to the HeNB under the local route roaming scence of correlation technique, and Fig. 3 is the configuration diagram that inserts EPS according to the HeNB under the local break-out roaming scence of correlation technique.Below in conjunction with Fig. 1, Fig. 2 and Fig. 3 the framework of EPS is described.

MME and EUTRAN, S-GW and base station from home (Home evolved NodeB, abbreviating HeNB as) gateway (HeNB GW) is connected, and is responsible for the related work of chains of command such as the processing of mobile management, Non-Access Stratum signaling and the contextual management of user's mobile management; S-GW is the accessing gateway equipment that links to each other with E-UTRAN, transmits data between E-UTRAN and P-GW, and is responsible for pending datas such as paging are carried out buffer memory; P-GW then is the borde gateway of EPS and packet data network (Packet Data Network abbreviates PDN as) network, and the access of being responsible for PDN reaches functions such as transmitting data between EPS and PDN.

Control (the Policy and Charging Control if EPS system support policy charges, abbreviate PCC as), "Policy and Charging Rules Function (Policy and Charging RulesFunction then, abbreviate PCRF as) carry out the strategy and the formulation of charging regulation, it is by receiving interface Rx and carrier network agreement (Internet Protocol, abbreviate IP as) application function (Application Function in the business network, abbreviate AF as) link to each other, obtain business information, be used to generate the business information of PCC strategy.When the S5 interface between S-GW and the P-GW adopts the GTP agreement, resident strategy and charge execution function (Policy and Charging Enforcement Function among the P-GW, abbreviate PCEF as), pass through Gx interface exchange message between PCRF and P-GW, be responsible for initiating the foundation of carrying, revise and release, guarantee service quality (the Quality of Service of business datum, abbreviate QoS as), and the control of chargeing.When the S5 of S-GW and P-GW interface adopts proxy-mobile IP (Proxy Mobile IP, abbreviate PMIP as) time, (the Bearer Binding and Event Report Function of resident bearing binding and event reporting function among the S-GW, abbreviate BBERF as), and by Gxc interface exchange message, be responsible for the foundation initiating to carry between S-GW and the PCRF, revise and discharge by BBERF, guarantee the service quality of business datum, by the PCEF control of chargeing.

EPS supports the access of HeNB, and HeNB is a kind of small-sized, lower powered base station, is deployed in indoor places such as family and office.Closed user group (Closed SubscriberGroup abbreviates CSG as) is to introduce the new ideas that propose behind the base station from home.Usually the user of an one family or an enterprises forms a closed user group, and this closed user group identifies with CSG ID.The base station from home of serving for user in this closed user group has identical CSG ID.When a closed user group was only served by a base station from home, this closed user group also can directly adopt base station from home sign (for example, BS ID) to identify.According to the gerentocratic wish of base station from home, CSG user and/or non-CSG user can distinguish different grades, and the priority difference is the service priority of its enjoyment then, and enjoying service quality can be different with class of service.

The user can be linked into the pairing base station from home of a plurality of closed user group by contracting with operator, for example, and user's office space, family etc.Therefore introduced the notion that allows the closed user Groups List.This tabulation is kept in the user data server of user's terminal and network side.

The use pattern of base station from home is divided into three kinds: closed mode, mixed mode and open mode.When the family expenses base station is closed mode, have only the affiliated CSG contracted user of this base station from home can insert this base station and enjoy the business that the base station provides.When the family expenses base station was open mode, any contracted user of operator can insert this base station, and the base station from home of this moment is equal to macro base station to be used.When the family expenses base station is mixed mode, same any contracted user of operator of permission or roamer insert use, but will be according to user's different rank of data separation of signatory CSG whether, the user who that is to say signatory this CSG has higher service priority when using the mixed type base station from home, enjoy better service quality and class of service.

When the user carried out the initialization access, the closed user group that the user data server of network side can insert the permission that the user contracts sent to the Mobility Management Entity of core net.The core network mobility management entity can utilize this information that UE is carried out access control.If UE is from undelegated closed mode base station from home visit core net, core net can be refused such user's access so.

HeNB inserts the core net of EPS usually by the fixed network circuit of renting.In order to ensure the safety of access, to introduce security gateway (Security Gateway abbreviates SeGW as) in the core net and shield, the data between HeNB and the SeGW will adopt IPSec to encapsulate.HeNB can be directly connected to the MME and the S-GW of core net by the ipsec tunnel that HeNB and SeGW set up, and also can be connected to MME and S-GW by HeNB GW again.Simultaneously, in order to realize that HeNB is managed, introduced network element base station from home management system (Home eNodeB Management System abbreviates HeMS as).

Because the QoS of the fixed network circuit that HeNB inserts normally is subjected to the owner of HeNB and fixed network operator's signatory restriction.Therefore, when the common HeNB of 3GPP UE inserted 3GPP core net access service, required QoS can not surpass the QoS that contracts of the fixed network circuit that the fixed network operator can provide.Otherwise the QoS of UE access service will can not get ensureing, particularly ensure bandwidth (Guaranteed Bitrate abbreviates GBR as).Therefore, for the 3GPP network, the QoS aggregate demand that must control the Operational Visit of all UE that insert by HeNB is no more than the signatory QoS guarantee of fixed network circuit that this HeNB inserts.

In addition, universal mobile telecommunications system (Universal Mobile TelecommunicationsSystem abbreviates UMTS as) is also supported the access of Home node base station HNB (Home NodeB).Fig. 4 is the configuration diagram that inserts UMTS according to the HNB under the non-roaming scene of correlation technique, Fig. 5 is the configuration diagram that inserts UMTS according to the HNB under the local route roaming scence of correlation technique, and Fig. 6 is the configuration diagram that inserts UMTS according to the HNB under the local break-out roaming scence of correlation technique.The framework of framework among Fig. 4, Fig. 5 and Fig. 6 and Fig. 1, Fig. 2 and Fig. 3 is similar, different is, use service universal packet wireless business affair support node (Serving General packet radio service supportnode, abbreviate SGSN as) replaced S-GW, use ggsn (Gateway General Packet Radio S ervice Supporting Node abbreviates GGSN as) to replace P-GW.

Under the situation of family expenses base station, must consider that a plurality of base station from home (for example, HeNB, HNB) insert the scene of 3GPP core net by a signatory fixed network circuit by signatory fixed network circuit access.At this moment, for the 3GPP network, the QoS aggregate demand that must control the Operational Visit of all subscriber equipmenies (User Equipment abbreviates UE as) that insert by these a plurality of base station from home is no more than the signatory QoS guarantee of the same fixed network circuit of these a plurality of base station from home accesses.

And in correlation technique, when the different user devices of shared same signatory fixed network circuit inserts by one or more base station from home, network side may be selected different PCRF for each subscriber equipment, like this, just caused in correlation technique, the signatory QoS that uncontrollable shared same signatory fixed network circuit has still selected total Operational Visit QoS demand of the subscriber equipment of different PCRF to be no more than this signatory fixed network circuit ensures.

For the foundation of the IP-CAN session of other UE that insert same base station from home (HeNB or HNB) or insert other base station from home but these base station from home and base station from home in the foregoing description insert the foundation of IP-CAN session of other UE of identical signatory fixed network circuit, can adopt the corresponding flow process realization of Figure 14 to Figure 19 according to different network scenarios.

In the prior art, when having only HeNB to be mixed mode and closed mode, just CSG information can be reported P-GW, and further report PCRF, and when open mode, not report P-GW and PCRF.In an embodiment of the present invention, only receive broadband connection information and when not receiving CSG information, PCRF can think that the HeNB that UE inserts is an open mode as PCRF.In like manner, I-PCRF can think that also the HeNB that this UE inserts is an open mode.In following embodiment, in the CSG information of mentioning, the pattern that HeNB inserts comprises open mode, mixed mode and closed mode.

In the flow process of embodiment one to embodiment six, broadband connection information is to report PCRF by PCEF or BBERF.Because base station from home can report broadband connection information when base station from home management system (abbreviating base station from home H (e) MS as) is registered.Therefore for non-roaming scene, PCRF can obtain broadband connection information by inquiry H (e) MS, and for roaming scence, V-PCRF can obtain broadband connection information by inquiry H (e) MS.

In another embodiment of the present invention, I-PCRF receives the QoS information of PCRF and/or the request mark of QoS information; I-PCRF authorizes to broadband policy control framework BPCF request QoS according to the request mark of QoS information and/or QoS information, and wherein, the IP-CAN session QoS authorization requests of setting up by same signatory fixed network circuit is from same I-PCRF.

Preferably, I-PCRF receive PCRF QoS information and/request mark of QoS information before, PCRF can formulate or upgrade QoS information; PCRF sends to I-PCRF with QoS information and indication information, and wherein, this indication information is used to indicate I-PCRF that bandwidth resources are carried out following processing one of at least: distribute, upgrade, QoS information comprises: ARP and GBR.

For resource discharged, PCRF determined the bandwidth resources of the QoS information that release has been authorized; Sign and indication information that PCRF will determine to discharge the QoS of bandwidth resources send to I-PCRF, and wherein, this indication information is used to indicate I-PCRF to discharge bandwidth resources.

If BCPF sends the message that refusal distributes or upgrade bandwidth resources, then I-PCRF judges one of at least that according to following can QoS information seize signatory fixed network circuit and be the resource of other QoS information distribution: the closed subscriber group (CSG) information that obtains by PCRF, the ARP in the QoS information.

I-PCRF indication BPCF discharges the bandwidth resources of other QoS information of being seized; After BPCF discharged resource, I-PCRF indicated BCPF to distribute once more or increases the identical bandwidth resources of bandwidth resources size of distributing or increasing with request for the first time; BPCF distributes or increases bandwidth resources, and returns and accept message.

Preferably, I-PCRF sends message to PCRF, wherein, carries the request mark of other QoS information of being seized in the message; PCRF sends message to BBERF and/or PCEF, the request mark corresponding strategy rule of request deletion or deexcitation QoS information; Perhaps, PCRF upgrades the request mark corresponding strategy rule of QoS information, and the policing rule after will upgrading sends to BBERF and/or PCEF.

Following embodiment is the variant embodiment of the foregoing description, below this is described respectively.

Embodiment seven

Present embodiment is described is to need to ask, revise because of access service or discharge in the process of QoS resource the flow process that PCRF, I-PCRF and BPCF are mutual according to certain UE that the flow process of Figure 14 or Figure 15 is set up the IP-CAN session.

Figure 20 is the flow chart according to the embodiment of the invention seven, and this flow process comprises the steps:

Step S2001:PCRF carries out strategic decision-making after receiving the resource modifying request message that business information that AF provides or UE initiate.Decision-making comprises following 3 kinds:

(a) if AF provides new business information or UE to initiate new resource allocation request, then PCRF carries out QoS and authorizes to formulating the PCC rule, and QoS rule (the IP-CAN session of adopting Figure 15 flow process to set up).Comprise QCI, ARP, GBR and MBR in the QoS information of this PCC rule or QoS rule.

(b) if the AF informing business stops or UE initiates resource release request, then the QoS that carries out of PCRF authorizes the PCC rule for deletion or deexcitation correspondence, and QoS rule (the IP-CAN session of adopting Figure 15 flow process to set up).This to delete or the QoS information of deexcitation PCC rule or QoS rule in comprise QCI, ARP, GBR and MBR.

(c) revise the resource of having distributed if AF is provided by the business information or the UE request that provide, the QoS of PCRF mandate is to upgrade established PCC rule so, and QoS rule (the IP-CAN session of adopting Figure 15 flow process to set up).Comprise QCI, ARP, GBR and MBR in the QoS information of this PCC rule or QoS rule.

Step S2002:PCRF sends intercommunication session QoS request message to I-PCRF, and request I-PCRF QoS authorizes.

If the PCRF decision-making is (a), then PCRF distributes new resource to the I-PCRF request, and the PCRF request of carrying in message distributes the indication of new resource, newly formulates the QoS information in the PCC rule, and a QoS request mark giving this QoS information distribution.Wherein comprise ARP and GBR at least in the QoS information.ARP represents the priority of this QoS information, and GBR represents to ask the bandwidth resources GBR of I-PCRF distribution, and the QoS request mark is used to identify the QoS information of this request;

If the PCRF decision-making is (b), then PCRF discharges the resource of having distributed to the I-PCRF request.The PCRF request of carrying in message discharges the indication of resource, and to delete or the sign of the QoS information that deexcitation PCC rule is corresponding (promptly regularly in this PCC rule new system, PCRF is the QoS request mark of this QoS information distribution when I-PCRF request Resources allocation) need discharge the resource of the QoS information of QoS request mark sign to notify I-PCRF;

If the PCRF decision-making is (c), then PCRF upgrades the resource of having distributed to the I-PCRF request.PCRF carries in message and asks more new resources indication, the QoS request mark that upgrades the QoS information in the PCC rule of back and distributed (promptly in this PCC rule new system regularly, PCRF is when I-PCRF request Resources allocation, QoS request mark for this QoS information distribution), need upgrade the resource of the QoS information of QoS request mark sign with notice I-PCRF;

Step S2003:I-PCRF sends broadband session QoS request message to BPCF, and request BPCF QoS authorizes.

If the message that I-PCRF receives is the request Resources allocation,, the I-PCRF request of carrying in message distributes the indication of new resource and the GBR in the QoS information so, and BPCF distributes bandwidth resources GBR with request;

If the message that I-PCRF receives discharges resource for request,, then the I-PCRF request of carrying in message discharges the indication of resource and the GBR in the QoS information, and BPCF discharges bandwidth resources GBR with request;

If the message that I-PCRF receives is for asking more new resources, I-PCRF will ask to BPCF with the increment that distributes GBR according to the GBR in the QoS information of upgrading so, if the GBR after upgrading has reduced, then the GBR that carries in message of I-PCRF is the increment of GBR, and request BPCF discharges bandwidth resources GBR increment; If the GBR after upgrading has increased, then to carry GBR in message be the GBR increment to I-PCRF, and request BPCF distributes bandwidth resources GBR increment;

Step S2004:BPCF carries out corresponding strategy according to the request message of I-PCRF.

If the BPCF request of receiving distributes bandwidth resources GBR, BPCF carries out resource and admission according to the signatory current available bandwidth situation of fixed network circuit.If remaining available bandwidth is more than or equal to GBR, then BPCF receives the request of I-PCRF, and returns confirmation of receipt message to I-PCRF, and BPCF will deduct GBR from the signatory current available bandwidth of fixed network circuit simultaneously; If remaining available bandwidth is less than GBR, the then request of BPCF refusal I-PCRF, and return refuse information to I-PCRF, and in carry the bandwidth that BPCF can accept;

If the BPCF request of receiving discharges bandwidth resources GBR, then BPCF directly returns confirmation of receipt message, and BPCF will increase GBR in the current available bandwidth of signatory fixed network circuit simultaneously.

Step S2005:I-PCRF carries out strategic decision-making according to the BPCF return messages.

If it is confirmation of receipt message (comprise and receive resource allocation and resource release), then execution in step S2009 that I-PCRF receives;

If it is refuse information that I-PCRF receives, I-PCRF will be according to priority ARP in the QoS information and the following logic determines of CSG information and executing of initiating the UE of this QoS request so:

(a) if the access module in the CSG information is a mixed mode, and the member relation of initiating the UE of this QoS request is non-CSG user,

(a1) if having other QoS information that this user oneself authorized or other QoS information of having authorized of other non-CSG users of inserting by same signatory fixed network circuit, I-PCRF compares this QoS and other QoS information according to the ARP in the QoS information so, if this QoS information can't be seized other QoS information, then execution in step S2014.If this QoS information can be seized the resource of other QoS information, execution in step S2006 then;

(a2) other QoS information that this user oneself authorized are if there is no arranged or other non-CSG users' of inserting by same signatory fixed network circuit the QoS information of having authorized, then execution in step S2014.

(b) if mixed mode during the access module in the CSG information, and the member relation of initiating the UE of this QoS request is CSG user,

(b1) if having other QoS information that other non-CSG users' that insert by same signatory fixed network circuit QoS authorizes, then this QoS information will be seized the QoS information of other QoS mandates;

(b2) if there is no other non-CSG users' the QoS QoS information of authorizing, so I-PCRF according to ARP with this QoS information and this user oneself QoS other QoS information of authorizing and the every other CSG user's that inserts by same signatory fixed network circuit the QoS information of having authorized compare, if this QoS information can't be seized other QoS information, then execution in step S2014.If this QoS information can be seized the QoS information resources that other CSG users have authorized, then execution in step S2006;

(c) if the pattern of the access in the CSG information is open mode or closed mode, so I-PCRF according to ARP with this QoS information and this user oneself QoS other QoS information of authorizing and the every other user's that inserts by same signatory fixed network circuit the QoS information of having authorized compare, if this QoS information can't be seized other QoS information, then execution in step S2014.If this QoS information can be seized the resource of the QoS information that other users have authorized, then execution in step S2006.

Step S2006: the flow process of carrying out Figure 23, Figure 24 or Figure 25.After carrying out this step, the residual available bandwidth of signatory fixed network circuit will be more than or equal to the GBR in this QoS information.

Step S2007:I-PCRF sends broadband session QoS request message to BPCF once more, carries the bandwidth GBR that the request among the step S2002 distributes.

Step S2008:BPCF Resources allocation is returned the message of accepting confirmation to I-PCRF.

Step S2009:I-PCRF returns acknowledge message to PCRF, carries the acceptance indication.

Step S2010: if the IP-CAN session of adopting Figure 14 flow process to set up, then PCRF gives information to BBERF transmission gateway control and QoS rule.

If the PCRF decision-making is (a), then PCRF carries new formulation QoS Rule Information in message;

If the PCRF decision-making is (b), then PCRF carries in message and will delete or deexcitation QoS Rule Information;

If the PCRF decision-making is (c), then PCRF carries in message and upgrades back QoS Rule Information.

Step S2011: if the IP-CAN session of adopting Figure 15 flow process to set up, then BBERF carries out the QoS rule, and returns acknowledge message to PCRF.

Step S2012:PCRF sends policy charging rule to PCEF and gives information.

If the PCRF decision-making is (a), then PCRF carries new formulation PCC Rule Information in message;

If the PCRF decision-making is (b), then PCRF carries in message and will delete or deexcitation PCC Rule Information;

If the PCRF decision-making is (c), then PCRF carries in message and upgrades back PCC Rule Information.

Step S2013:PCEF returns acknowledge message to PCRF, and flow process finishes.

Step S2014:I-PCRF returns acknowledge message to PCRF, carries the refusal indication.PCRF returns QoS mandate refuse information according to the refusal indication to AF or UE, and flow process finishes.

Figure 21 is the flow chart according to the embodiment of the invention eight, and this flow process comprises the steps:

Step S2101:H-PCRF carries out strategic decision-making after receiving the resource modifying request message that business information that AF provides or UE initiate.Decision-making comprises following 3 kinds:

(a) if AF provides new business information or UE to initiate new resource allocation request, then H-PCRF carries out QoS and authorizes to formulating the PCC rule, and the QoS rule.Comprise QCI, ARP, GBR and MBR in the QoS information of this PCC rule or QoS rule.

(b) if the AF informing business stops or UE initiates resource release request, then H-PCRF carries out QoS and authorizes and be the PCC rule of decision deletion or deexcitation correspondence, and QoS rule.This to delete or the QoS information of deexcitation PCC rule or QoS rule in comprise QCI, ARP, GBR and MBR.

(c) revise the resource of having distributed if AF is provided by business information or the UE request provide, H-PCRF carries out QoS and authorizes and be so, upgrades established PCC rule, and the QoS rule.Comprise QCI, ARP, GBR and MBR in the QoS information of this PCC rule or QoS rule.

Step S2102:H-PCRF sends S9 session rule to V-PCRF and gives information, and according to the difference of H-PCRF decision-making, carries new formulation QoS rule, or the QoS rule after the QoS of deletion or deexcitation rule or the renewal.

Step S2103:V-PCRF sends intercommunication session QoS request message to I-PCRF, and the QoS of request I-PCRF authorizes.

If the H-PCRF decision-making is (a), then V-PCRF distributes new resource to the I-PCRF request, and the V-PCRF request of carrying in message distributes the indication of new resource, newly formulates the QoS information in the QoS rule, and a QoS request mark giving this QoS information distribution.Wherein comprise ARP and GBR at least in the QoS information.ARP represents the priority of this QoS information, and GBR represents to ask the bandwidth resources GBR of I-PCRF distribution, and the QoS request mark is used to identify the QoS information of this request;

If the H-PCRF decision-making is (b), then V-PCRF discharges the resource of having distributed to the I-PCRF request.The V-PCRF request of carrying in message discharges the indication of resource, and to delete or the sign of the QoS information that deexcitation QoS rule is corresponding (promptly regularly in this QoS rule new system, V-PCRF is the QoS request mark of this QoS information distribution when I-PCRF request Resources allocation) need discharge the resource of the QoS information of QoS request mark sign to notify I-PCRF;

If the H-PCRF decision-making is (c), then V-PCRF upgrades the resource of having distributed to the I-PCRF request.V-PCRF carries in message and asks more new resources indication, the QoS request mark that upgrades the QoS information in the QoS rule of back and distributed (promptly in this QoS rule new system regularly, V-PCRF is when I-PCRF request Resources allocation, QoS request mark for this QoS information distribution), need upgrade the resource of the QoS information of QoS request mark sign with notice I-PCRF;

Step S2104:I-PCRF sends broadband session QoS request message to BPCF, and the QoS of request BPCF authorizes.
