Description

A kind of method and system of call access control

Technical field

The present invention relates to wireless communication field, a kind of method and system of call access control is particularly related to.

Background technology

Third generation partner program (3rd Generation Partnership Project, referred to as 3GPP) is developed Evolved packet system (Evolved Packet System, referred to as EPS) by mobile management unit (Mobility Management Entity, referred to as MME), gateway (Serving Gateway, referred to as S-GW), Packet Data Network Network diagram closes (Packet Data Network Gateway, referred to as P-GW), home subscriber server (Home Subscriber Server, referred to as HSS) etc. network element composition, as shown in Figure 1.

MME is responsible for the control such as mobile management, the processing of Non-Access Stratum signaling and management of user's mobile management context The related work in face；S-GW is accessed in user and data is forwarded between P-GW, and is responsible for caching the pending datas such as paging； P-GW is then EPS and packet data network (Packet Data Network, referred to as PDN) network borde gateway, is responsible for PDN access and the function such as forwarding data between EPS and PDN.

If EPS support policy charging control (Policy and Charging Control, referred to as PCC), then "Policy and Charging Rules Function (Policy and Charging Rules Function, referred to as PCRF) entity carries out strategy With the formulation of charging regulation, it passes through interface Rx and carrier network agreement (Internet Protocol, referred to as IP) business Application function (Application Function, referred to as AF) in network is connected, and business information is obtained, for generating PCC The business information of strategy.When the S5 interfaces between S-GW and P-GW use GTP agreements, reside strategy in P-GW and charging is held Row function (Policy and Charging Enforcement Function, referred to as PCEF), passes through between PCRF and P-GW Gx interfaces exchange information, responsible to initiate carrying foundation, modification and release, it is ensured that the service quality (Quality of business data transmission Of Service, referred to as QoS), and carry out charging control.When S-GW and P-GW S5 interfaces use proxy-mobile IP (Proxy Mobile IP, referred to as PMIP) when, bearing binding and event reporting function (Bearer Binding and are resident in S-GW Event Report Function, referred to as BBERF), and information is exchanged by Gxc interfaces between S-GW and PCRF, by BBERF is responsible for initiating carrying foundation, modification and release, it is ensured that the service quality of business datum, and charging control is carried out by PCEF.

User can be by Universal Terrestrial Radio Access Network (the Evolved Universal Terrestrial of evolution Radio Access Network, referred to as E-UTRAN) it is linked into EPS networks.

In addition, user can also pass through the home base station system of evolution (Home evolved NodeB subsystem, letter Referred to as HeNB subsystems) access EPS networks.In the network shown in fig. 1, user can also pass through base station from home subsystem (Home NodeB subsystem) is linked into circuit commutative field (Circuit Switched Domain, referred to as CS) development The CS business such as voice.Wherein, HeNB or HNB (HeNB/HNB) are a kind of small-sized, low power base stations, are deployed in family and office Deng indoor place.HeNB/HNB generally passes through the fixed network circuit access mobile core net of rental.In order to ensure access safety, core Introduce security gateway (Security Gateway, referred to as SeGW) in net to be shielded, the number between HeNB/HNB and SeGW It will be packaged according to interaction using IPSec, fixed network equipment can not perceive the data of HeNB/HNB and mobile core network interaction. HeNB can be directly connected to MME, can also be connected to MME by HeNBGW.HeNB GW are optional network element, and HNB GW are must Network selection member.In order to support CS business, HNB GW and mobile switching centre (Mobile Switching Center, referred to as MSC) Between set up interface, when user carries out CS business, in order to CS service implementation QoS guarantees, there is C-x between HNB GW and PCRF Interface.In addition, there is HeNB management systems (HeNB Management System, referred to as HeNB MS) in HeNB subsystems, The information related for managing HeNB.

Except HNB supports CS business, and HeNB is not supported outside the characteristic, HeNB access systems and HNB access systems There is similitude.Because the present invention is not concerned with the support to CS traffic performances, therefore only said below by taking HeNB access systems as an example It is bright.

HeNB it is upper electricity, to HeNB GW initiate registration process as shown in Fig. 2 including：

Step 201, HeNB is initialized, and the configuration information of itself is obtained from HeNB MS；Also to perform HeNB GW's simultaneously Discovery procedure, obtains the HeNB GW information of initial service.

Step 202, ipsec tunnel is set up between HeNB and SeGW.

Step 203, SCTP (Stream is set up between HeNB and HeNB GW pre-configured port Control Transmission Protocol, referred to as SCTP) transmission session.

Step 204, HeNB sends the positional information for including HeNB in HeNB login request messages, message to HeNB GW (HeNB Location Info), HeNB mark (HeNB Identity), HeNB operational parameters (HeNB Operating Parameters, such as PLMN ID, Cell id) and HeNB operation modes (HeNB Operating Mode, such as HeNB CSG id etc.) information.

Step 205, HeNB GW obtain above- mentioned information from HeNB login request messages, check whether the note for receiving HeNB Volume；If received, HeNB registration received messages are returned；If refusal, HeNB registration reject message is returned.

After electricity completes the processes such as registration on HeNB, UE initiates to register to HeNB GW.HeNB sends out information related UE HeNB GW are given, to carry out Access Control to UE on HeNB GW, UE membership qualification are verified, and notify UE accesses institute The HeNB used, its flow is as shown in Figure 3：

Step 301, UE initiates initial NAS programs, and RRC connections are set up between HeNB, UE is identified and UE capability reportings To HeNB.

Step 302, at the beginning of UE transmissions RRC initially directly transmits (RRC Initial Direct Transfer) message bearing Beginning NAS message (such as location update request message Location Updating Request), comprising information such as IMSI, sends To HeNB.

Step 303, HeNB checking steps 301 are provided UE marks and UE abilities, check whether UE supports CSG, and HeNB is certainly Whether body supports CSG.If the RRC connections in step 301 set up program and UE marks are not supplied into HeNB, i.e., on HeNB The corresponding context id of the UE are not present, then HeNB needs to initiate UE accreditation processes (correspondence subsequent step 304~306), Before UE registration requests are initiated, HeNB also needs to identify to UE acquisition requests UE.If existed on HeNB corresponding with UE Context id, then need not perform UE accreditation processes (not performing subsequent step 304~306).

Step 304, it is assumed that the corresponding context id of the upper UE of HeNB are not present, then HeNB is obtained after UE marks, HeNB performs UE registrations by sending UE registration requests (UE Register Request) message to HeNBGW.UE registration requests UE marks and UE abilities (for example indicating whether UE is CSG user) are included in message.

Step 305, HeNB GW check UE abilities, if UE abilities indicate not support CSG, or HeNB not to support CSG, So HeNB GW perform Access Control or checking UE uses the qualification of the HeNB.When HeNB GW determine to receive UE registrations, it is UE distribution context id.

Step 306, HeNB GW return to UE registration receiving (UE Register Accept) message to HeNB, include distribution Context id to UE.For non-CSG UE, HeNB GW are also stored with CSG information.If HeNB GW do not receive UE registrations, Then return to UE registration rejects (UE Register Reject) message.

Step 307, HeNB sends RUA CONNECT message to HeNB GW, carries RANAP initial UE message.

Step 308, RUA CONNECT message triggers HeNB GW are set up to core net (Core network, referred to as CN) SCCP connections.SCCP connection request messages comprising HeNB CSG ID are sent to CN network elements by HeNB GW.

Step 309, CN network elements return to SCCP connection confirmation messages to HeNB GW.

Step 310, CN network elements optionally perform mobile management program, such as authentication procedure.Under CSG patterns, CN network elements Access authentication is performed to UE, or in a hybrid mode, CN network elements perform qualification testing to UE.

Step 311, after being authorized to UE accesses, HeNB and HeNB GW is continued through and carry out NAS programs (for example Location updating program).

The QoS resource of fixed network circuit is needed to use when accessing EPS by fixed network circuit due to HeNB, the QoS resource is led to The signing for being subjected to HeNB owner and fixed network operator is limited, and this part generally is distributed into the fixed network resource that HeNB uses claims For HeNB signings QoS.When 3GPP UE are by HeNB access services, requirement of the business to QoS no more than HeNB signings QoS, Otherwise the development of the business cannot QoS guarantees, influence business experience.For requiring to ensure bit rate (Guaranteed Bitrate, referred to as GBR) business it is even more so.In this regard, for the framework shown in Fig. 1, introducing a set of resource management and control machine System is fixed and mobile network resource to be managed collectively.BPCF (BroadBandPolicy Control are introduced in fixed network side Function, broadband policy control function) it is used for managing fixed network resource；PCRF is introduced in mobile network side to be used to manage mobile money Source, and set up between BPCF and PCRF the intercommunication that S9* interfaces realize policy in resource management.When UE is commenced business by HeNB When, in order to ensure business experience, PCRF is needed for service authorization mobile network resource, while PCRF is needed the business pair QoS requirement is sent to BPCF by S9* interfaces, and call access control is carried out for BPCF, to ensure having corresponding fixed network resource allocation To HeNB, carry out the business for the user and use.

There is CSG (Closed Subscriber Group, closed user group) area by the same HeNB users accessed Point, for example certain customers are CSG user, are partly non-CSG user, or are hybrid subscriber.When resource is nervous, it should need The need for preferential guarantee CSG user commences business.In addition, user also possesses different ARP (Allocation and Retention Priority, distribution and holding priority) information, it is low that the high user of ARP priority can seize ARP priority User resource.According to prior art, BPCF can obtain ARP information, but not obtain the related CSG information of user, Therefore according to prior art, BPCF can not commence business carry out call access control according to CSG information for user, this may result in as Lower problem occurs：

For example, user A and user B are accessed by same HeNB, user A is CSG user, and ARP is relatively low；User B is non-CSG User, ARP is higher.User B has carried out business, and now user A also commences business, and BPCF enters to the user A business carried out Anxiety occurs for row call access control, the fixed network resource used due to now licensing to HeNB, and user A ARP priority is relatively low, nothing Method seizes the resource of other users, therefore BPCF will exclude user A and carry out the business.And in fact, due to user A For CSG user, the user B commenced business is non-CSG user, and network should preferentially ensure the need that CSG user commences business Will, it now can not just ensure that above-mentioned user A business is carried out according to existing admission control mechanism.

For another example, user A and user B are accessed by same HeNB, and user A is non-CSG user, and ARP is higher；User B is CSG User, ARP is relatively low.User B has carried out business, and now user A also commences business, and BPCF enters to the user A business carried out Row call access control, it is nervous due to now authorizing the fixed network resource that HeNB is used to occur, but BPCF is according to the ARP priority received Judge that user A ARP priority is higher, user B priority is relatively low, then BPCF receives user A and carries out the business.Cause This, according to BPCF call access control result, bearer network can be by seizing the relatively low user B of ARP priority resource, to ensure The business that the high user A of ARP priority carries out.But in fact user A is non-CSG user, and user B is CSG user, and network should The preferential guarantee user B commences business, rather than preferential guarantee user A commences business.

For scene mentioned above, in the case of fixed network resource is authorized on HeNB using occurring anxiety, according to existing Call access control realize technology, it is impossible to commenced business offer QoS guarantee for CSG user.

The content of the invention

In view of this, it is a primary object of the present invention to provide a kind of method and system of call access control, to solve In the case of fixed network resource is authorized on HeNB using occurring anxiety, existing call access control realizes that technology can not be opened for CSG user The problem of exhibition industry business provides QoS guarantee.

Above-mentioned CN network elements can be S-GW or P-GW or ePDG etc..

Wherein, the first user is access base station from home, the user (user in such as subsequent embodiment of latency services mandate A)；Second user is to access base station from home, the user commenced business (the user B in such as subsequent embodiment), here, first User and second user access for same base station from home, and second user is one or more.

Illustrate the solution of the present invention below by specific embodiment.

Embodiment one

The application scenarios of the embodiment are：When BPCF to the call access control result of user for refusal when, by HeNB according to CSG Information and ARP information perform second of call access control to the user, and (i.e. HeNB performs resource according to CSG information and ARP information Seize).Wherein, the CSG information of user is obtained when UE accesses HeNB.

The embodiment application precondition be：Assuming that user A is CSG user, user B is non-CSG user, user A's Resource seize ability less than user B resource seize ability, i.e. user A ARP priority it is relatively low, user B priority is higher； User B has been commenced business, and network (fixed network and mobile network) is commenced business for user B and is assigned with resource.HeNB authorizes QoS Commenced business by user B shared, then user A is can not be on the premise of preempting resources, and workable HeNB authorizes QoS The QoS demand that user A commences business can not be met, now, HeNB performs process such as Fig. 5 institutes of second of call access control Show, including：

Step 501, PCRF receives the mandate triggering commenced business for user A, and for example PCRF is received by Rx interface The application layer service negotiation information that user A commences business, it is desirable to commenced business to user A and carry out QoS using network bearer resource Authorize；

Step 502, PCRF combines the business information received from Rx interface, user signing contract information, mobile operator strategy User A is commenced business and carries out QoS mandates, produces and authorizes QoS (authorizing QoS to include the information such as mandate QCI, MBR and GBR), PCRF will authorize QoS to be included in PCC rules or QoS rules.

Step 503, user A mandate QoS is included in PCC rules or QoS rules and issued by S9* interfaces by PCRF To BPCF, request BPCF is commenced business carry out call access control to user A according to authorizing QoS (i.e. according to QCI, MBR and GBR)；Bag Carried containing QoS PCC rules or QoS rules is authorized in call access control request message.

Step 504, after BPCF receives the call access control request message from PCRF, on the HeNB accessed according to user A HeNB authorize QoS, call access control is carried out to user A mandate QoS.Now, because part HeNB authorizes QoS to be already allocated to The other users (being user B in the embodiment) for accessing the HeNB are used, and remaining available HeNB authorizes QoS can not meet user A mandate QoS, therefore BPCF refusals are for user A call access control request.

Step 505, BPCF returns to call access control refusal respond message to PCRF.

Step 506, PCRF is received after call access control refusal respond message, PCRF to CN network elements (such as P-GW or S-GW or EPDG) distributing policy, including：The user A produced in step 502 mandate QoS；In addition, received according to PCRF in step 505 Also need to indicate comprising call access control in call access control refusal respond message, the strategy that PCRF is issued, the call access control indicates to use In showing that HeNB mandates QoS is nervous, BPCF excludes user A and commenced business, it is desirable to which HeNB carries out second of call access control.

Step 507, after CN network elements receive the strategy that PCRF is issued, return and respond to PCRF.

Step 508, CN network elements perform the strategy that PCRF is issued, and are operated according to authorizing QoS to carry out corresponding carrying, to HeNB GW send carrying operation requests, and (carrying operation requests can be that carrying is set up or modification request, or RAB distribution refers to Show), and be that user A commences business reserved corresponding bearing resource according to QoS is authorized；Carry and authorize in the carrying operation requests QoS and call access control are indicated.

Step 509, HeNB GW are received after carrying operation requests, reserved corresponding according to authorizing QoS to be commenced business for user A Bearing resource, and the carrying operation requests that authorize QoS and call access control to indicate will be carried be sent to HeNB.

Step 510, HeNB is received after carrying operation requests, and indicating to know according to call access control therein needs carry out second Secondary call access control, then according to the user CSG information and/or ARP information itself preserved (embodiment middle finger user A and user B's CSG information and/or ARP information) second of call access control of progress of being commenced business to user A.Now, although user A resource is robbed Account for resource of the ability less than user B and seize ability, but user A is CSG user, user B is non-CSG user, and therefore, HeNB leads to Cross and seize user B bearing resource to receive user A mandate QoS, that is, receive user A to commence business.

Step 511, it is the reserved carryings accordingly of user A according to QoS is authorized when HeNB determines that receiving user A commences business Resource, and return to successfully carrying operation response to HeNB GW.

Step 512, HeNB GW return to successfully carrying operation response to CN network elements.

Step 513, HeNB initiate simultaneously user B carrying release process (need the network element for performing carrying release have HeNB, HeNB GW and CN network element), bearing resources whole release user B.

Step 514, HeNB is initiated and the radio bearer resources distribution between UE (user A) according to user A mandate QoS Process.

Step 515, during the carrying release of step 513, when CN network elements know the bearing resource for needing to discharge user B Afterwards, CN network elements report carrying release event to PCRF, including user B mandate QOS (authorize QOS be included in PCC rules or In QoS rules).

Step 516, PCRF is returned to CN network elements and responded.

Step 517, PCRF carries out policy update, mainly deletes user B mandate QOS.

Step 518, the strategy after renewal is handed down to BPCF by PCRF by S9* sessions, carries out authorizing QoS more for BPCF Newly.

Embodiment two

When BPCF to the call access control result of user for refusal when, user is held according to CSG information and ARP information by HeNB Second of call access control of row (i.e. HeNB performs resource according to CSG information and ARP information and seized).Wherein, the CSG information of user exists UE is obtained when accessing HeNB.

The embodiment application precondition be：Assuming that user A is non-CSG user, user B is CSG user, user A's Resource seizes resource of the ability less than user B and seizes ability.User B has commenced business, and network (fixed network and mobile network) is Commenced business for user B and be assigned with resource.It is shared that HeNB authorizes QoS to be commenced business by user B, then user A is in nothing On the premise of method preempting resources, workable HeNB authorizes QoS can not meet the QoS demand that user A commences business, this When, HeNB according to CSG information and ARP perform second of call access control process as shown in fig. 6, including：

The processing of step 601~609 is with step 501~509, and here is omitted.

Step 610, HeNB is received after carrying operation requests, and indicating to know according to call access control therein needs carry out second Secondary call access control, then according to the user CSG information and/or ARP information itself preserved (embodiment middle finger user A and user B's CSG information and/or ARP information) to user A mandate QoS second of call access control of progress.Because user A resource seizes energy Resource of the power less than user B seizes ability, and user A is non-CSG user, and user B is CSG user, and therefore, user A carries out industry Business can not seize user B bearing resource, and HeNB excludes user A mandate QoS, that is, excludes user A and commence business.

Step 611, when HeNB excludes user A and commenced business, HeNB is operated to the HeNB GW carryings for returning to failure to be rung Should.

Step 612, when HeNB GW receive the carrying operation response of failure, the reserved bearing resources of user A are released to, and The carrying operation response of failure is sent to CN network elements.

Step 613, CN network elements are received after the carrying operation response of failure, be released to the reserved bearing resources of user A and User A mandate QOS, while by bearer operation failure reporting events to PCRF.

Step 614, PCRF is returned to CN network elements and responded.

Step 615, PCRF carries out policy update, deletes user A mandate QOS, and now the mandate QOS on BPCF need not Update.

Embodiment three

The scene and precondition of embodiment description are identical with embodiment one, and difference is to carry operating process：Implement In example one, before second of call access control, the mandate QoS that HeNB to CN sides has been issued according to PCRF has carried out bearing resource It is reserved.But, carry out second of call access control once HeNB and exclude when user commences business, it is necessary to pre- to CN sides to HeNB The bearing resource stayed re-starts release, in order to reduce the frequency that HeNB carries out resource allocation and release to the network element of CN sides, this Embodiment provides another call access control processing mode.

In addition, when embodiment one describes HeNB according to CSG information and/or ARP information second of call access control of progress, User A is received to commence business by discharging user B whole bearing resources；And the present embodiment proposition is another way： By reducing user B mandate QoS (the part bearing resource for discharging user B), to receive user A to commence business.The process As shown in fig. 7, comprises：

The processing of step 701~707 is with step 501~507, and here is omitted.

Step 708, the strategy issued according to PCRF, CN network elements issue mandate QoS to HeNB GW and call access control is indicated.
