Description

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 (3rdGenerationPartnershipProject, referred to as 3GPP) the grouping system (EvolvedPacketSystem of evolution, referred to as EPS) by the Universal Terrestrial Radio Access Network (EvolvedUniversalTerrestrialRadioAccessNetwork of evolution, referred to as E-UTRAN), mobile management unit (MobilityManagementEntity, referred to as MME), gateway (ServingGateway, referred to as S-GW), grouped data network gateway (PacketDataNetworkGateway, referred to as P-GW), home subscriber server (HomeSubscriberServer, referred to as HSS) composition, Fig. 1 is the configuration diagram accessing EPS according to the HeNB under the non-roaming scene of correlation technique, Fig. 2 is the configuration diagram accessing EPS of the HeNB under the local route roaming scence according to correlation technique, Fig. 3 is the configuration diagram accessing EPS of the HeNB under the local break-out roaming scence according to correlation technique.Below in conjunction with Fig. 1, Fig. 2 and Fig. 3, the framework of EPS is illustrated.

MME and EUTRAN, S-GW and base station from home (HomeevolvedNodeB, referred to as HeNB) gateway (HeNBGW) is connected, and is responsible for the related work of the chain of command such as management of mobile management, the process of Non-Access Stratum signaling and user's mobile management context; S-GW is the accessing gateway equipment being connected with E-UTRAN, forwards data, and be responsible for the pending datas such as paging are carried out buffer memory between E-UTRAN and P-GW; P-GW is then the borde gateway of EPS and packet data network (PacketDataNetwork, referred to as PDN) network, is responsible for the access of PDN and forwards the functions such as data between EPS and PDN.

If EPS support policy charging controls (PolicyandChargingControl, referred to as PCC), then "Policy and Charging Rules Function (PolicyandChargingRulesFunction, referred to as PCRF) carry out tactful and charging regulation formulation, it passes through receiving interface Rx and carrier network agreement (InternetProtocol, referred to as IP) application function (ApplicationFunction in business network, referred to as AF) it is connected, obtain business information, for generating the business information of PCC strategy. When S5 interface between S-GW and P-GW adopts GTP agreement, P-GW resides strategy and charge execution function (PolicyandChargingEnforcementFunction, referred to as PCEF), by Gx interface exchange information between PCRF and P-GW, it is responsible for initiating the foundation of carrying, amendment and release, it is ensured that the service quality (QualityofService of business datum, referred to as QoS), and carry out charging control. When the S5 interface of S-GW and P-GW adopts proxy-mobile IP (ProxyMobileIP, referred to as PMIP) time, resident bearing binding and event reporting function (BearerBindingandEventReportFunction in S-GW, referred to as BBERF), and by Gxc interface exchange information between S-GW and PCRF, BBERF it is responsible for initiating the foundation of carrying, amendment and release, ensure the service quality of business datum, PCEF carry out charging control.

EPS supports the access of HeNB, and HeNB is a kind of base station small-sized, lower powered, is deployed in the indoor place such as family and office. The new ideas that closed user group (ClosedSubscriberGroup, referred to as CSG) proposes after being introduced into base station from home. The user of usual one family or an enterprises forms a closed user group, and this closed user group CSGID is identified. For the base station from home of user's service in this closed user group, there is identical CSGID. When a closed user group is only by a base station from home service, this closed user group can also directly adopt base station from home mark (such as, BSID) to be identified. Can distinguishing different grades according to the gerentocratic wish of base station from home, CSG user and/or non-CSG user, the service priority of different then its enjoyment of priority, enjoys service quality and class of service can be different.

User is by being linked into base station from home corresponding to multiple closed user group with operator signing, for instance, the office space of user, family etc. Therefore the concept allowing closed subscriber group list is introduced. This list is saved in the terminal of user and the user data server of network side.

The use pattern of base station from home is divided into three kinds: closed mode, mixed model and open mode. When base station from home is closed mode time, only CSG contracted user belonging to this base station from home can access this base station and enjoy the business that base station provides.When base station from home is open mode time, any operator contracted user can access this base station, and base station from home now is equal to macro base station and uses. When base station from home is mixed model time, also allow for any operator contracted user or roamer accesses use, but whether to contract the different rank of the data separation of CSG according to user, that is the user of this CSG of contracting has higher service priority using when mixed type base station from home, enjoys better service quality and class of service.

When user carries out initializing and accesses time, the user data server of network side can be sent to the closed user group allowing to access of user's signing the Mobility Management Entity of core net. Core network mobility management entity can utilize this information that UE is carried out Access Control. If UE accesses core net from undelegated closed mode base station from home, then core net can refuse the access of such user.

HeNB accesses the core net of EPS usually by the fixed network circuit rented. In order to ensure the safety of access, introducing security gateway (SecurityGateway, referred to as SeGW) and shield in core net, employing IPSec is packaged by the data between HeNB and SeGW. HeNB can be directly connected to MME and the S-GW of core net by HeNB and the SeGW ipsec tunnel set up, it is also possible to is connected to MME and S-GW again through HeNBGW. Meanwhile, in order to realize that HeNB is managed, introduce network element base station from home management system (HomeeNodeBManagementSystem, referred to as HeMS).

Owing to the QoS of the HeNB fixed network circuit accessed usually is subject to the owner of HeNB and the signing restriction of fixed network operator. Therefore, when the usual HeNB of 3GPPUE accesses 3GPP core net access service, required QoS not can exceed that the QoS of the signing of the fixed network circuit that fixed network operator can be provided by. Otherwise, the QoS of UE access service will can not get ensureing, particularly ensure bandwidth (GuaranteedBitrate, referred to as GBR). Therefore, for 3GPP network, it is necessary to control the QoS guarantee that the QoS aggregate demand of the Operational Visit by the HeNB all UE accessed is contracted less than this HeNB fixed network circuit accessed.

Additionally, UMTS (UniversalMobileTelecommunicationsSystem, referred to as UMTS) also supports the access of Home node base station HNB (HomeNodeB). Fig. 4 is the configuration diagram accessing UMTS according to the HNB under the non-roaming scene of correlation technique, Fig. 5 is the configuration diagram accessing UMTS of the HNB under the local route roaming scence according to correlation technique, and Fig. 6 is the configuration diagram accessing UMTS of the HNB under the local break-out roaming scence according to correlation technique. Framework in Fig. 4, Fig. 5 and Fig. 6 is similar with the framework of Fig. 1, Fig. 2 and Fig. 3, the difference is that, use service universal packet wireless business business support node (ServingGeneralpacketradioservicesupportnode, referred to as SGSN) instead of S-GW, ggsn (GatewayGeneralPacketRadioServiceSupportingNode, referred to as GGSN) is used to instead of P-GW.

When base station from home is accessed by fixed network circuit of contracting, it is necessary to consider that multiple base station from home (such as, HeNB, HNB) accesses the scene of 3GPP core net by a fixed network circuit of contracting. At this moment, for 3GPP network, the signing QoS guarantee of the same fixed network circuit that the QoS aggregate demand of Operational Visit of all subscriber equipmenies (UserEquipment, referred to as UE) that must control to be accessed by these multiple base station from home is accessed less than these multiple base station from home.

And in the related, when the different user devices of shared same signing fixed network circuit is accessed by one or more base station from home, network side is likely each subscriber equipment and selects different PCRF, so, result in the related, it is impossible to the total Operational Visit QoS demand controlling to share the subscriber equipment that same signing fixed network circuit still have selected different PCRF ensures less than the signing QoS of this signing fixed network circuit.

I-PCRF can independently dispose and be in the mobile operator network belonged to base station (HeNB, HNB) owner, can also strengthen as the function of BPCF, be deployed in the network of the fixed network operator that the rented fixed network circuit of base station from home owner belongs to. For same carrier network, it is possible to dispose multiple I-PCRF. Unification is authorized to be asked to BPCF by an I-PCRF by same base station from home or multiple base station from home and the plurality of base station from home by the QoS of the 3GPPUE of the same signing fixed network circuit core network access all IP-CAN sessions set up. (being the deployment that BPCF function strengthens for I-PCRF, it is possible to understand that ask QoS to authorize for PCRF to a BPCF).

Fig. 7 is the flow chart of authorization requests method according to embodiments of the present invention, and this flow process comprises the steps:

Step S702, UE set up IP-CAN session by base station from home (such as, HeNB, HNB) request, and wherein, this base station from home is by signing fixed network connection to 3GPP core net;

Step S704, PCRF are that IP connects Access Network session (IPConnectivityAccessNetwork, referred to as IP-CAN) session selection I-PCRF, wherein, select same I-PCRF for the IP-CAN session set up by same signing fixed network circuit;

Step S706, the I-PCRF that this PCRF request selecting goes out carries out QoS mandate for this IP-CAN session.

PCRF selected by the IP-CAN session set up for same UE can be different, and can also be different for the PCRF selected by the different UE IP-CAN session set up. But, by above-mentioned steps S702 to step S704, owing to, in IP-CAN session establishment process, being identical to PCRF its affiliated signing fixed network circuit reported, therefore each PCRF will select same I-PCRF for all these IP-CAN.

Wherein, PCRF can send the broadband connection information of this signing fixed network circuit to I-PCRF. PCRF can obtain broadband connection information in the following manner:

PCEF or BBERF receives request and sets up the message of IP-CAN session, wherein, carries the broadband connection information of the signing fixed network circuit that IP-CAN session establishment passes through in this message; PCEF or BBERF sends broadband connection information to PCRF.

Preferably, PCRF can also by the CSG information reporting of UE to I-PCRF. Such I-PCRF just can know the access module of this UE HeNB accessed, and the member relation of CSG belonging to this UE and base station from home. When, after the QoS request of resource situation refusal I-PCRF current according to signing fixed network circuit for BPCF, I-PCRF will carry out further decision-making according to the CSG information of IP-CAN session and/or the User Priority etc. of initiating QoS request. Determine to discharge the resource of non-CSG user or lower-priority subscriber, in order to distribute to CSG user or higher-priority subscriber uses.

Wherein, the IP-CAN session that UE sets up does not have BBERF. The concrete steps of Figure 19 are similar with the step of Figure 18. The main distinction is: PCEF is in visited network, and this IP address can be notified H-PCRF by V-PCRF after UE distributes IP address by the P-GW that PCEF is positioned at.

For accessing the foundation of the IP-CAN session of other UE setting up or accessing other base station from home but these base station from home signing fixed network circuit identical with the base station from home access in above-described embodiment of the IP-CAN session of other UE of same base station from home (HeNB or HNB), the corresponding flow process of Figure 14 to Figure 19 can be adopted to realize according to different network scenarios.

In the prior art, when only HeNB is mixed model and closed mode, just by CSG information reporting to P-GW, and PCRF can be reported further, and when open mode, not report P-GW and PCRF. In an embodiment of the present invention, when PCRF only receives broadband connection information without when receiving CSG information, PCRF is it is believed that the HeNB that UE accesses is open mode. In like manner, I-PCRF is it is also assumed that the HeNB that this UE accesses is open mode. Below in an example, in the CSG information mentioned, the pattern that HeNB accesses includes open mode, mixed mode and closed mode.

Preferably, receive the QoS information of PCRF and the request mark of/QoS information at I-PCRF before, PCRF can formulate or update QoS information; QoS information and instruction information are sent to I-PCRF by PCRF, and wherein, this instruction information is for indicating I-PCRF that bandwidth resources are carried out the process of at least one of: distribution, renewal, QoS information includes: ARP and GBR.

For discharging for resource, PCRF determines the bandwidth resources discharging the QoS information authorized; The mark and instruction information of determining the QoS of release bandwidth resources are sent to I-PCRF by PCRF, and wherein, this instruction information is used for indicating I-PCRF to discharge bandwidth resources.

If BCPF sends refusal distribution or updates the message of bandwidth resources, then according at least one of, I-PCRF judges that can QoS information seize the resource that signing fixed network circuit has distributed as other QoS information: the ARP in the closed subscriber group (CSG) information that obtained by PCRF, QoS information.

I-PCRF indicates BPCF to discharge the bandwidth resources of other QoS information being preempted; After BPCF discharges resource, I-PCRF again indicates that BCPF distributes or increases the bandwidth resources identical with the bandwidth resources size of first time request distribution or increase; BPCF distributes or increases bandwidth resources, and return accepts message.

Preferably, I-PCRF sends message to PCRF, wherein, carries the request mark of other QoS information being preempted in message; PCRF sends message to BBERF and/or PCEF, and request is deleted or the request of deexcitation QoS information identifies corresponding policing rule; Or, PCRF updates the policing rule of the request mark correspondence of QoS information, and the policing rule after updating is sent to BBERF and/or PCEF.

Example below is the variant embodiment of above-described embodiment, below this is illustrated respectively.

Embodiment seven

What the present embodiment described is set up in certain UE of IP-CAN session process needing request, amendment or release QoS resource because of access service according to the flow process of Figure 14 or Figure 15, the flow process that PCRF, I-PCRF and BPCF are mutual.

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

Step S2001:PCRF carries out strategic decision-making after receiving the business information of AF offer or the resource modifying request message of UE initiation. Decision-making includes following 3 kinds:

If a () AF provides new business information or UE to initiate new resource allocation request, then PCRF carries out QoS mandate for formulating PCC rule, and QoS rule (the IP-CAN session that employing Figure 15 flow process is set up). The QoS information of this PCC rule or QoS rule comprises QCI, ARP, GBR and MBR.

If b () AF notifies that business terminates or UE initiates resource release request, then the QoS that PCRF carries out authorizes the PCC rule for deleting or deexcitation is corresponding and QoS rule (adopting the IP-CAN session that Figure 15 flow process is set up). This to be deleted or to comprise QCI, ARP, GBR and MBR in the QoS information of deexcitation PCC rule or QoS rule.

If allocated resource is revised in c business information that () AF amendment has been provided that or UE request, then the QoS of PCRF authorizes as updating established PCC rule, and QoS rule (adopting the IP-CAN session that Figure 15 flow process is set up). The QoS information of this PCC rule or QoS rule comprises QCI, ARP, GBR and MBR.

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

If PCRF decision-making is (a), then PCRF distributes new resource to I-PCRF request, PCRF carries the instruction of the new resource of request distribution, the new QoS information formulated in PCC rule in the message, and gives a QoS request mark of this QoS information distribution. QoS information wherein at least includes ARP and GBR. ARP table shows the priority of this QoS information, and GBR represents the bandwidth resources GBR of request I-PCRF distribution, and QoS request mark is for identifying the QoS information of this request;

If PCRF decision-making is (b), then PCRF discharges allocated resource to I-PCRF request. PCRF carries the instruction of request release resource in the message, and to delete or the mark of QoS information that deexcitation PCC rule is corresponding is (namely in this PCC rule brand-new timing, when PCRF is to I-PCRF request Resources allocation, for the QoS request mark that this QoS information is distributed) to notify that I-PCRF needs the resource of the QoS information of release QoS request Identification;

If PCRF decision-making is (c), then PCRF updates allocated resource to I-PCRF request. PCRF carries in the message and asks more new resources instruction, after renewal, the QoS information in PCC rule and allocated QoS request mark are (namely in this PCC rule brand-new timing, when PCRF is to I-PCRF request Resources allocation, for the QoS request mark that this QoS information is distributed), to notify that I-PCRF needs to update the resource of the QoS information of QoS request Identification; ;

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

If the message that I-PCRF receives is request Resources allocation, then I-PCRF carries the GBR in the instruction asking to distribute new resource and QoS information in the message, to ask BPCF to distribute bandwidth resources GBR;

If the message that I-PCRF receives is request release resource, then I-PCRF carries the GBR in the instruction and QoS information asking release resource in the message, to ask BPCF to discharge bandwidth resources GBR;

If the message that I-PCRF receives is for asking more new resources, so I-PCRF will to ask to BPCF with the increment distributing GBR according to the GBR in the QoS information updated, if the GBR after updating reduces, the increment that GBR is GBR that then I-PCRF carries in the message, and ask BPCF to discharge bandwidth resources GBR increment; If the GBR after updating adds, then I-PCRF carries GBR in the message is GBR increment, and asks BPCF to distribute bandwidth resources GBR increment;

The step S2004:BPCF request message according to I-PCRF, performs corresponding strategy.

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

If BPCF receives request release bandwidth resources GBR, then BPCF directly returns reception confirmation message, and BPCF will increase GBR in signing fixed network circuit current available bandwidth simultaneously.

Step S2005:I-PCRF returns message according to BPCF and carries out strategic decision-making.

If it is receive to confirm message (including receiving resource distribution and resource release) that I-PCRF receives, then perform step S2009;

If this QoS information can seize the resource of other QoS information, then perform step S2006;

(a2) if there is no there are this user oneself other QoS information authorized or the authorized QoS information of other the non-CSG users by the access of same signing fixed network circuit, then perform step S2014.

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

(b1) if having by same signing fixed network circuit access other non-CSG users QoS authorize other QoS information, then this QoS information will seize other QoS authorize QoS information;

If this QoS information can seize the authorized QoS information resource of other CSG users, then perform step S2006;

If c the pattern of the access in () CSG information is open mode or closed mode, so I-PCRF according to ARP other QoS information this QoS information and this user oneself QoS authorized and is compared by the authorized QoS information of the every other user of same signing fixed network circuit access, if this QoS information cannot seize other QoS information, then perform step S2014. If this QoS information can seize the resource of the authorized QoS information of other users, then perform step S2006.

Step S2006: perform the flow process of Figure 23, Figure 24 or Figure 25. After performing this step, the residual available bandwidth of signing fixed network circuit will be greater than the GBR being equal in this QoS information.

Step S2008:BPCF Resources allocation, returns, to I-PCRF, message of accepting confirmation.

Step S2009:I-PCRF returns to PCRF and confirms message, carries acceptance instruction.

Step S2010: if adopting the IP-CAN session that Figure 14 flow process is set up, then PCRF sends gateway control and QoS rule offer message to BBERF.

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

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

If PCRF decision-making is (c), then PCRF carries QoS Rule Information after renewal in the message.

Step S2011: if adopting the IP-CAN session that Figure 15 flow process is set up, then BBERF performs QoS rule, and confirms message to PCRF return.

Step S2012:PCRF provides message to PCEF sending strategy charging regulation.
