Description

Method for managing resource, system and home base station policy function

Technical field

The present invention relates to the communications field, in particular to a kind of method for managing resource, system and home base station policy function.

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 base station from home (HomeevolvedNodeB, referred to as HeNB) under the non-roaming scene of correlation technique.Below in conjunction with Fig. 1, the framework of EPS is described.

MME and EUTRAN, S-GW are connected with home base-station gateway (HeNBGW), the related work of the chains of command such as the process of responsible mobile management, Non-Access Stratum signaling and the contextual management of user's mobile management; S-GW is the accessing gateway equipment be connected with E-UTRAN, forwarding data between E-UTRAN and P-GW, and is responsible for carrying out buffer memory to pending datas such as pagings; P-GW is then the borde gateway of EPS and packet data network (PacketDataNetwork, referred to as PDN) network, be responsible for PDN access and between EPS and PDN the function such as forwarding data.

EPS supports the access of HeNB, and HeNB is a kind of small-sized, lower powered base station, is deployed in the indoor place such as family and office.Closed user group (ClosedSubscriberGroup, referred to as CSG) is the new ideas proposed after introducing base station from home.The user of usual one family or an enterprises forms a closed user group, and this closed user group CSGID identifies.For the base station from home of user's service in this closed user group has identical CSGID.When a closed user group only has a base station from home service, this closed user group also directly can adopt base station from home to identify (such as, BSID) and identify.According to the gerentocratic wish of base station from home, CSG user and/or non-CSG user can distinguish different grades, and different then its service priority enjoyed of priority, enjoys service quality and class of service can be different.

User by contracting the base station from home that can be linked into corresponding to multiple closed user group with operator, such as, the office space, family etc. of user.Therefore the concept allowing closed subscriber group list is introduced.This list is kept in the terminal of user and the user data server of network side.

The using forestland of base station from home is divided into three kinds: closed mode, mixed mode and open mode.When base station from home is closed mode time, only have 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 is now equal to macro base station and uses.When base station from home is mixed mode time, the any operator contracted user of same permission or roamer access use, but rank that will be different according to the data separation of the whether signing CSG of user, that is the user of this CSG signing has higher service priority when use mixed type base station from home, enjoys better service quality and class of service.

When user's initialization accesses time, the closed user group of the permission access that the user data server of network side can be contracted user is sent to the Mobility Management Entity of core net.Core network mobility management entity can utilize this information to carry out access control to UE.If UE is from undelegated closed mode base station from home access core net, so core net can refuse the access of such user.

HeNB accesses the core net of EPS usually by the fixed network circuit (also claiming broadband access (BroadbandAccess is called for short BBF)) rented.In order to ensure the safety of access, introduce security gateway (SecurityGateway, referred to as SeGW) in core net and shield, employing IPSec encapsulates by the data between HeNB and SeGW.HeNB can be directly connected to MME and S-GW of core net by the ipsec tunnel set up between HeNB and SeGW, also can be connected to MME and S-GW (namely HeNBGW is optional in EPS) by HeNBGW again.Meanwhile, in order to realize managing HeNB, network element is introduced: base station from home management system (HomeeNodeBManagementSystem, referred to as HeMS).

The QoS (service quality) of fixed network circuit due to HeNB access is normally subject to the owner of HeNB and the signing restriction of fixed network operator.Therefore, when 3GPPUE accesses 3GPP core net access service by HeNB, required QoS can not exceed the signing QoS of the fixed network circuit that fixed network operator can provide.Otherwise the QoS of UE access service will can not get ensureing, particularly ensure bandwidth (GuaranteedBitrate, referred to as GBR).Therefore, for 3GPP network, the QoS that the fixed network circuit that the QoS aggregate demand that must control the Operational Visit of all UE accessed by HeNB is no more than this HeNB access is contracted ensures.

In addition, universal mobile telecommunications system (UniversalMobileTelecommunicationsSystem, referred to as UMTS) also supports the access of Home node base station HNB (HomeNodeB).Fig. 2 is the configuration diagram accessing UMTS according to the HNB under the non-roaming scene of correlation technique.The framework of Fig. 2 and Fig. 1 is similar, unlike, 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.In umts, HNBGW is essential.

When base station from home is by signing fixed network circuit access, the scene of multiple base station from home (such as, HeNB, HNB) by a signing fixed network circuit access 3GPP core net must be considered.At this moment, for 3GPP network, the QoS aggregate demand that must control the Operational Visit of all subscriber equipmenies (UserEquipment, referred to as UE) by this multiple base station from home access is no more than the signing QoS guarantee of the same fixed network circuit of this multiple base station from home access.

At present, a kind of framework controlled for base station from home access strategy has been proposed, as shown in Figure 3.H (e) HBPolicyFunction (home base station policy function) and H (e) NB subsystem (comprising H (e) NBGW and SeGW) interface, and policy control is carried out to base station from home access.Fig. 4 be HeNB access time, there is not the framework of HeNBGW, now H (e) NBPolicyFunction respectively with SeGW and MME interface.

Fig. 5 is after in prior art, H (e) NB powers on, the interaction diagrams of H (e) NB subsystem and H (e) NBPolicyFunction.

After step S501:H (e) NB powers on, obtain the subscriber terminal equipment (CustomerPremisesEquipment that BBF Access Network distributes, be called for short CPE) IP address, H (e) NB CPEIP address and SeGW carry out IKEv2 Signalling exchange, set up ipsec tunnel.In this process, SeGW be H (e) NB distribute H (e) NBIP address, for H (e) NB and other 3GPP network elements mutual.；

Step S502:SeGW notifies the incidence relation of CEPIP address and H (e) NBIP address to H (e) NBPolicyFunction;

Step S503:H (e) NBPolicyFunction returns and accepts message after preserving incidence relation;

Step S504:H (e) NB and H (e) NBGW or MME sets up S1 or Iuh and connects;

Step S505:H (e) NBGW or MME and H (e) NBPolicyFunction sets up T2 session, wherein carries CSGID and H (e) NBIP address;

T2 session associates with step S502 according to H (e) NBIP address by step S506:H (e) NBPolicyFunction, thus obtain the CPEIP address of this H (e) NB, H (e) NBPolicyFunction determines the BPCF (BroadbandPolicyControlFramework, broadband policy controls framework) of the BBF Access Network that H (e) NB accesses according to CPEIP address.H (e) NBPolicyFunction sets up S9* session to BPCF, carries CPEIP address;

Step S507:BPCF returns response message;

Step S508:H (e) NBPolicyFunction returns response message to H (e) NBGW or MME.

By above-mentioned flow process, the S9* session that H (e) NBPolicyFunction and BPCF establishes, the fixed network Backhaul (back haul link) that this BPCF is used for H (e) NB accesses carries out policy control.

Fig. 6 is in prior art, UE by H (e) NB initially adhere to or service request time, the flow chart that H (e) NBPolicyFunction and BPCF is mutual.

Step S601:UE performs initial attachment or service request (Idle state is to connected state conversion);

Step S602:MME or SGSN sends carrying through H (e) NBGW to H (e) NB and sets up request or RAB assignment request;

After step S603:H (e) NBGW receives above-mentioned message, send request the message of bearer authorization to H (e) NBPolicyFunction, in message, carry H (e) NBIP address, and QoS information.If this H (e) NB is mixed mode, CSG member's instruction of this UE also can be carried;

Step S604:H (e) NBPolicyFunction determines CPEIP address according to H (e) NBIP address, adopts the S9* session of setting up in Fig. 5 to ask QoS to authorize to BPCF, carries QoS information;

Step S605:BPCF is according to QoS information, and the current resource situation of fixed network Backhaul that H (e) NB accesses carries out call access control, returns response message to H (e) NBPolicyFunction.BPCF can accept or refuse QoS and authorize;

Step S606:H (e) NBPolicyFunction returns response message to H (e) NBGW, accepts or refusal mandate;

Step S607:H (e) NB returns carrying to MME or SGSN and sets up or RAB appointment response.

Step S603-step S606 and step S607 carries out simultaneously.

If in step S606, H (e) NBGW receives the instruction that refusal is authorized, and so H (e) NBGW will initiate the RAB assignment request of deleting load-bearing request or request release wireless access resource.

Fig. 7 is in prior art, in carrying (PDN context) activation/amendment/deactivation process, and the interaction flow of H (e) NBPolicyFunction and BPCF.

Step S701:MME or SGSN receives activation/amendment/deexcitation bearing request message;

Step S702:MME or SGSN sends corresponding request message through H (e) NBGW to H (e) NB;

After step S703:H (e) NBGW receives above-mentioned message, send request the message of bearer authorization to H (e) NBPolicyFunction, in message, carry H (e) NBIP address, and QoS information.If this H (e) NB is mixed mode, CSG member's instruction of this UE also can be carried;

Step S704:H (e) NBPolicyFunction determines CPEIP address according to H (e) NBIP address, adopts the S9* session of setting up in Fig. 5 to ask QoS to authorize to BPCF, carries QoS information;

Step S705:BPCF is according to QoS information, and the current resource situation of fixed network Backhaul that H (e) NB accesses carries out call access control, returns response message to H (e) NBPolicyFunction.BPCF can accept or refuse QoS and authorize;

Step S706:H (e) NBPolicyFunction returns response message to H (e) NBGW, accepts or refusal mandate;

Step S707:H (e) NB returns carrying to MME or SGSN and sets up or RAB appointment response.

Step S703-step S706 and step S707 carries out simultaneously.

If in step S706, H (e) NBGW receives the instruction that refusal is authorized, so H (e) NBGW will initiate the RAB assignment request of deleting load-bearing request or request release wireless access resource, to refuse the carrying/amendment request of this UE.

By above 3 flow processs, the resource that prior art can realize the UE request dispatching of this H (e) NB of all accesses can not exceed the summation of the backhual current available resource that this H (e) NB connects, thus ensure that carrying out smoothly of each business of each UE.

In above flow process, after BPCF is according to current resource situation refusal authorization requests, regardless of active user's situation of current carrying or user, foundation or the amendment request of respective carrier all will be rejected, for the situation carried or user class is higher, this is obviously reasonable not.

Embodiment

According to existing procedure, when H (e) NB is mixed mode, if the Member Users of existing non-CSG accesses H (e) NB access service, current backhaul resource has been used up or has been about to use up, when CSG Member Users initiates access or carrying is set up/revises, the access or carrying of refusing this CSG Member Users according to current resource situation are set up/amendment by BPCF, and this is obviously very unreasonable.Same, if after the lower carrying access of priority, the carrying access of refusal high priority; Or after non-emergent service bearer access, all can there is irrational utilization of resources in the carrying access of refusal urgency traffic.

In order to make rational use of resources, the main thought of method for managing resource of the present invention, system and home base station policy function is, when Current resource deficiency, home base station policy function (H (e) NBPolicyFunction) is according to the strategy execution call access control pre-established, the mode taking resource by discharging other carryings is that current carrying obtains enough resources, realizes code reassignment and the Appropriate application of resource.

Such as, for mixed mode, when the bearing resource setting up or revise CSG member is not enough, interrupt or delete access or the carrying of those non-CSG members.In addition, each carrying also has priority, and the user therefore for identical CSG member relation carries, and when backhual runs out of resource sets, when BPCF returns refusal mandate, should carry out the code reassignment of resource according to the priority of carrying.

As shown in figure 12, method for managing resource of the present invention, the method comprises:

Step 101: home base station policy function (H (e) NBPolicyFunction) receives the response message that broadband policy controls the request QoS mandate that framework (BPCF) sends;

During the response message instruction refusal that step 102: described request QoS authorizes, described home base station policy function is according to preset strategy execution call access control.

Described home base station policy function comprises according to preset strategy execution call access control:

According to preset strategy, described home base station policy function judges whether the carrying that described request QoS authorizes seizes other bearing resources;

When judging to seize, described in described home base station policy function triggers, be preempted the deexcitation flow process of carrying.

When judging to seize, described home base station policy function also sends to the request end of bearer authorization the response message that bearer authorization is agreed in instruction, otherwise sends the response message of instruction refusal bearer authorization to described request end.

According to the business experience ensureing different carryings or user, can formulate different strategies, strategy can comprise the contents such as the condition that the range of choice strategy being preempted carrying, the selecting sequence strategy being preempted carrying or resource seize.

Described strategy is: when base station from home pattern is mixed mode, performs call access control according to closed user group (CSG) member relation; Or,

Priority (ARP) is kept to perform call access control according to distribution; Or,

Base station from home be open mode or closed mode time, according to ARP perform call access control; Base station from home pattern is in mixed mode situation, performs call access control according to closed user group (CSG) member relation and/or ARP.

Particularly, different base station from home patterns can formulate different tactful contents:

Base station from home be open mode or closed mode time, according to distribution keep priority (ARP), described carrying seize other users carrying resource; Such as: that selects to meet resource preemptive condition from the carrying lower than current carrying allocation retention priority (ARP) is preempted carrying;

Base station from home pattern is in mixed mode situation, and when the user of described carrying correspondence is closed user group (CSG) member, described carrying is seized the resource of non-CSG Member Users carrying and/or seized the resource of other CSG Member Users carrying according to ARP; When the user of described carrying correspondence is non-CSG member, keep priority (ARP) according to distribution, the resource of other non-CSG Member Users carryings is seized in described carrying.

Particularly, base station from home be mixed mode and the user of described carrying correspondence for CSG member time, the selecting sequence being preempted carrying is first select from the carrying of non-CSG member, then select from the carrying of CSG member.

The described one or more and described one or more resource being preempted carrying that is carried as be preempted is more than or equal to described carrying request authorization resources.

When the response message instruction refusal that described request QoS authorizes is authorized, carry current available resource information simultaneously; Described resource seize after available resources be current available resource and be describedly preempted resource sum.

Described home base station policy function judges preempting resources, if be preempted resource to be greater than current carrying request dispatching resource, then to described BPCF request release difference resource; If be preempted resource to be less than current carrying request dispatching resource, then to described BPCF request dispatching difference resource.

Carry current bearing identification in the message of described request bearer authorization, when described home base station policy function initiates load bearing deactivation flow process, trigger and be preempted the bearing identification carrying in the message of the deexcitation of carrying and be preempted carrying.

Hereinafter also describe the present invention in detail with reference to accompanying drawing in conjunction with the embodiments.It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.

Embodiment 1

Fig. 8 be initially adhered to by H (e) NB at UE according to the embodiment of the present invention, ask PDN connect, tracing section updating/Routing Area Update or service request time, the flow chart 1 that H (e) NBPolicyFunction and BPCF is mutual.This flow process comprises the steps:

Step S801:UE performs initial attachment, request PDN connection, tracing section updating/Routing Area Update or service request (Idle state is to connected state conversion);

Step S802:MME or SGSN sets up request or RAB assignment request to H (e) NBGW to transmission carrying.

After step S803:H (e) NBGW receives above-mentioned message, send request the message of bearer authorization to H (e) NBPolicyFunction, in message, carry H (e) NBIP address, QoS request bearing identification, and QoS information.If this H (e) NB is mixed mode, CSG member's instruction of this UE also can be carried.This carrying of unique identification when QoS request bearing identification is mutual for H (e) NBGW and H (e) NBPolicyFunction.QoS request bearing identification, can be that H (e) NBGW distributes, also the embodiment that user ID and EPS bearing identification (for EPS) combination or user ID and Network layer Service Access Point Identifier (NetworklayerServiceAccessPointIdentifier is called for short NSAPI) (i.e. the bearing identification of UMTS system) (for UMTS system) combine can be adopted;

For UMTS system, for the PDP Context of Non-GBR (not needing the business ensureing bandwidth), QoS information at least comprises Traficclass (type of service), ARP (Allocation/RetentionPriority, allocation retention priority), MBR (maximum bit rate); For the PDP Context of GBR, QoS information at least comprises Traficclass, ARP, GBR (GuaranteedBitRate ensures bit rate), MBR.

For EPS, if initial access or request PDN connect, QoS information comprises QCI (QoSClassIdentifier, Qos classify ID), ARP and UE-AMBR (terminal Aggregate Maximum Bit Rate).If not initial access or request PDN connect, for Non-GBR carrying, QoS information comprises QCI, ARP, MBR; For GBR carrying, QoS information comprises QCI, ARP, GBR, MBR.

H (e) NBPolicyFunction now has following information: the using forestland (open, closed, mixed mode) of H (e) NB of this carrying access, if mixed mode, also there is member's indication information (CSG member, non-CSG member); The QoS information of this carrying.

Step S804:H (e) NBPolicyFunction determines CPEIP address according to H (e) NBIP address, adopt the S9* session of setting up in Fig. 5 to ask QoS to authorize to BPCF, carry bandwidth B R-Allocation and the instruction of request dispatching resource of request dispatching;

Wherein, if comprise GBR from the QoS information that H (e) NBGW obtains, so BR-Allocation can be set to the GBR in QoS information;

If obtain QoS information from H (e) NBGW and do not comprise GBR, so H (e) NBPolicyFunction can perform two kinds of strategies:

(1) BR-Allocatin is set according to MBR or UE-AMBR and local policy

(2) H (e) NBPolicyFunction processing locality, does not ask QoS to authorize to BPCF.

Step S805:BPCF is according to BR-Allocation, and the current resource situation of fixed network Backhaul that H (e) NB accesses carries out call access control, returns response message to H (e) NBPolicyFunction.If current available bandwidth is more than or equal to the bandwidth B R-Allocation of request dispatching, then BPCF returns acceptance instruction, if current available bandwidth is less than the bandwidth B R-Allocation of request dispatching, then the instruction of BPCF refusal, can carry current available bandwidth BR-Accept simultaneously;

Step S806:H (e) NBPolicyFunction, according to the return messages of BPCF, performs following strategic decision-making.

If what a () H (e) NBPolicyFunction received is accept instruction, then perform step S809;

If what b () H (e) NBPolicyFunction received is refusal instruction, then H (e) NBPolicyFunction performs call access control further according to the strategy formulated:

(b1) if the pattern that H (e) NB accesses is open mode, H (e) NBPolicyFunction carry (context) according to other of authorizing through BPCF of this carrying (PDP Context) and this user oneself being set up of ARP (Allocation/RetentionPriority) and set up by other users that same H (e) NB accesses authorize other to carry (PDP Context) through BPCF to compare:

If carrying (PDP Context) resource that this carrying (PDP Context) cannot seize other (namely, the ARP (Allocation/RetentionPriority) of this carrying (PDP Context) carries the ARP (Allocation/RetentionPriority) of (PDP Context) lower than other), then perform step S812;

If this carrying (PDP Context) can seize the resource of other carryings, and the current available bandwidth BR-Accept sum that bandwidth B R-Allocation ' and the BPCF that can seize other carryings (PDP Context) return is more than or equal to the bandwidth B R-Allocation of request dispatching, then perform step S807; Otherwise, then step S812 is performed;

(b2) if the pattern of HeNB access is mixed mode, and the member relation of the UE of this carrying (PDP Context) correspondence is non-CSG user, then:

(b21) if having other carryings (PDP Context) through BPCF mandate that this user oneself sets up or other carryings (PDP Context) through BPCF mandate of being set up by other non-CSG users that same H (e) NB accesses, so H (e) NBPolicyFunction will carry (PDP Context) according to ARP (Allocation/RetentionPriority) and carries (PDP Context) compare with other, if this carrying (PDP Context) cannot seize the resource of other carryings (PDP Context), then perform step S812, if this carrying (PDP Context) can seize the resource of other carryings (PDP Context), and the current available bandwidth BR-Accept sum that bandwidth B R-Allocation ' and the BPCF that can seize other carryings (PDP Context) return is more than or equal to the bandwidth B R-Allocation of request dispatching, then perform step S807, otherwise, then step S812 is performed, ,

(b22) other carryings (PDP Context) through BPCF mandate if there is no having this user oneself to set up or other carryings (PDP Context) through BPCF mandate of being set up by other non-CSG users that same H (e) NB accesses, then perform step S812.

(b3) if the access module of HeNB is mixed mode, and the member relation of the UE of this carrying (PDP Context) correspondence is CSG user, then:

(b31) if having other carryings (PDP Context) of authorizing through BPCF of other the non-CSG users' foundation accessed by H (e) NB, and the current available bandwidth BR-Accept sum that this carrying (PDP Context) carrying (PDP Context) bandwidth B R-Allocation ' authorized through BPCF that can seize that other non-CSG users set up and BPCF return is more than or equal to the bandwidth B R-Allocation of request dispatching, then perform step S807; Otherwise, what so H (e) NBPolicyFunction carried (PDP Context) according to other of authorizing through BPCF of this carrying (PDP Context) and this user oneself being set up of ARP (Allocation/RetentionPriority) further or passed through that other CSG users that same H (e) NB accesses set up authorize through BPCF, and other carry (PDP Context) and compare, if this carrying (PDP Context) cannot seize the resource of other carryings (PDP Context), then perform step S812; If this carrying (PDP Context) can seize CSG user set up through BPCF authorize other carrying (PDP Context) resource, and the current available bandwidth BR-Accept sum that the bandwidth B R-Allocation ' (comprising carrying that non-CSG user sets up and the carrying that CSG user sets up) that can seize other carryings (PDP Context) return with BPCF is more than or equal to the bandwidth B R-Allocation of request dispatching, then perform step S807; Otherwise, perform step S812;

(b32) other carryings (PDP Context) of authorizing through BPCF if there is no having the non-CSG user accessed by same H (e) NB to set up, what so other of authorizing through BPCF of carrying that (PDP Context) and this user oneself set up were carried (PDP Context) according to ARP (Allocation/RetentionPriority) or passed through that other CSG users that same H (e) NB accesses set up by H (e) NBPolicyFunction authorize through BPCF, and other carry (PDP Context) and compare, if this carrying (PDP Context) cannot seize the resource of other carryings (PDP Context), then perform step S812.If this carrying can seize the resource of other carryings (PDP Context), and the current available bandwidth BR-Accept sum that bandwidth B R-Allocation ' and the BPCF that can seize other carryings (PDP Context) return is more than or equal to BR-Allocaton, then perform step S707; Otherwise, perform step S812;
