The present invention relates to the communications field, in particular to a kind of processing method and system of secondary call access control.

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 the Universal Terrestrial Radio Access Network of evolution (EvolvedUniversal Terrestrial Radio Access Network, referred to as E-UTRAN), mobile management list First (MobilityManagement Entity, referred to as MME), gateway (Serving Gateway, referred to as S-GW), Grouped data network gateway (Packet Data Network Gateway, referred to as P-GW), home subscriber server (HomeSubscriber Server, referred to as HSS) is formed, as shown in Figure 1.

MME is connected with EUTRAN, S-GW and femto gateway (HeNB GW), is responsible for mobile management, Non-Access Stratum The related work of the chain of command such as the processing of signaling and the management of user's mobile management context；S-GW is connected with E-UTRAN Accessing gateway equipment, data are forwarded between E-UTRAN and P-GW, and be responsible for caching the pending datas such as paging；P-GW It is then EPS and packet data network (Packet Data Network, referred to as PDN) network borde gateway, is responsible for PDN's 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) carries out strategy and meter Take the formulation of rule, it passes through interface Rx and carrier network agreement (Internet Protocol, referred to as IP) business network In application function (Application Function, referred to as AF) be connected, obtain business information, for generate PCC strategy Business information.When the S5 interfaces between S-GW and P-GW use GTP agreements, strategy is resided in P-GW and charging performs work( Energy (Policy and Charging Enforcement Function, referred to as PCEF), is connect between PCRF and P-GW by Gx Information is changed in oral sex, is responsible for initiating the foundation of carrying, modification and release, ensures the service quality (Qualifyof of business datum 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 Bindingand 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 the foundation of carrying, modification and release, ensures the service quality of business datum, charging control is carried out by PCEF.

EPS supports evolution Home eNodeB (Home evolved NodeB, referred to as HeNB) access, and Fig. 1 is also described HeNB accesses the signal of EPS.HeNB is a kind of small-sized, low power base station, is deployed in the indoor place such as family and office. HeNB generally accesses EPS core nets by the fixed network circuit of rental.In order to ensure access safety, security gateway is introduced in core net (Securify Gateway, referred to as SeGW) is shielded, and the data interaction between HeNB and SeGW will use IPSec to carry out Encapsulation, fixed network equipment can not perceive the data of HeNB and EPS network interactions.HeNB can be directly connected to MME, can also pass through HeNB GW are connected to MME, i.e. HeNB GW are optional network elements.

In addition, UMTS (Universal Mobile Telecommunications System, referred to as For UMTS) support Home eNodeB HNB (Home NodeB) access.Fig. 2 is under non-roaming scence, and HNB accesses UMTS framework Schematic diagram.Framework shown in Fig. 2 is similar with Fig. 1 framework, and difference is, uses generic service packet wireless business support node (Serving General Packet Radio Service Support Node, referred to as SGSN) instead of S-GW, use Ggsn (Gateway General Packet Radio Service SupportingNode, referred to as GGSN) P-GW is instead of, HNB GW are essential network elements under the scene.

Due to needing to use the QoS resource of fixed network circuit, the QoS when HeNB/HNB is linked into EPS by fixed network circuit Resource is generally limited by the signing of HeNB/HNB owner and fixed network operator, and this part generally is distributed into HeNB/HNB makes Fixed network resource is referred to as HeNB/HNB signings QoS.When 3GPP UE are by HeNB/HNB access services, business is wanted to QoS Seek the signing QoS no more than HeNB/HNB, otherwise the development of the business cannot QoS guarantees, influence business experience, it is right It is even more so in the business for requiring guarantee bit rate (Guaranteed Bitrate, referred to as GBR).On the other hand, it is directed to Fig. 1 and figure Framework shown in 2, a set of resource mechanism of control is introduced to be managed collectively fixed and mobile network resource.Introduced in fixed network side BPCF (BroadBand Policy Control Function, broadband policy control function) is used for managing fixed network resource, is moving Dynamic network side introduces PCRF and is used to manage mobile resources, and S9 is established between BPCF and PCRF^*Interface realizes resource management The intercommunication of strategy.When UE initiates business by HeNB/HNB, the requirement that business carries out to QoS is sent to PCRF, by PCRF QoS mandates are carried out, mobile network carries out resource reservation according to mandate QoS in mobile network, while PCRF sends out the mandate QoS BPCF is given, the requirement that whether can meet to authorize QoS for the available HeNB in BPCF decision-making fixed networks side signings QoS, if can be with Meet, then need to be that business carries out reserved fixed network resource corresponding with the mandate QoS in fixed network side, will if can not meet Ask, then need to exclude user's development business.

Meanwhile prioritization be present by the same HeNB users accessed and (such as CSG (Closed be present SubscriberGroup, closed user group) priority, or ARP (Priority points of Allocation and Retention Match somebody with somebody and keep priority)).If a new User Priority for initiating business is excellent higher than the lower other users of same HeNB accesses First level, then (i.e. HeNB contracts QoS by the business of other users in the case where HeNB signing QoS resources use anxiety All take, or available HeNB signings QoS can not meet that the high-priority users initiate need of the business to QoS Ask), according to prior art, BPCF can also refuse the user and initiate the business when carrying out call access control.But from conjunction Manage management and control resource angle for, it is above-mentioned in this case, it should secondary admission control mechanism is realized by PCRF, that is, received To after the BPCF instruction excluded, PCRF still can be according to information such as all UE priority under HeNB accesses Call access control is carried out to the Client-initiated business again.In this case, because the priority of the user is used higher than other The priority at family, therefore low priority user is degraded using resource, while the business for receiving high-priority users to initiate, And provide Resource Guarantee.

Above-mentioned secondary admission control mechanism is realized, it is necessary that all UE under same HeNB accesses are by unification PCRF service, so as to PCRF receive BPCF exclude instruction in the case of, can be according to all UE under the HeNB The information such as priority are to the secondary call access control of Client-initiated business realizing.
