Description

The control method of base station from home access and system

Technical field

The present invention relates to the communications field, the control method accessed in particular to a kind of base station from home and system.

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.

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 chains of command such as mobile management, the process of 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 is only served by a base station from home, 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 carries out initialization access 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, 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.The ipsec tunnel that HeNB can be set up by HeNB and SeGW is directly connected to MME and S-GW of core net, 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, introduce base station from home management system (HomeeNodeBManagementSystem, referred to as HeMS) network element.

The QoS 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 the usual HeNB of 3GPPUE accesses 3GPP core net access service, 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).

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 2.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.But prior art only provides a rough framework, how to carry out policy control or a problem to be solved.
