Description

Control method and system that base station from home inserts

Technical field

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

Background technology

Third generation partner program (3rd Generation Partnership Project; Abbreviate 3GPP as) grouping system (the Evolved Packet System of evolution; Abbreviate EPS as) by Universal Terrestrial Radio Access Network (the Evolved Universal Terrestrial Radio Access Network of evolution; Abbreviate E-UTRAN as), mobile management unit (Mobility Management Entity; Abbreviate MME as), gateway (Serving Gateway; Abbreviate S-GW as), grouped data network gateway (Packet DataNetwork Gateway abbreviates P-GW as), home subscriber server (Home Subscriber Server abbreviates HSS as) form.

MME and EUTRAN, S-GW and base station from home (Home evolved NodeB abbreviates HeNB as) gateway (HeNB GW) is connected, the related work of chains of command such as the processing of responsible mobile management, Non-Access Stratum signaling and the contextual management of user's mobile management; S-GW is the accessing gateway equipment that links to each other with E-UTRAN, between E-UTRAN and P-GW, transmits data, and is responsible for pending datas such as paging are carried out buffer memory; P-GW then is the borde gateway of EPS and packet data network (Packet Data Network abbreviates PDN as) network, and the access of being responsible for PDN reaches functions such as between EPS and PDN, transmitting data.

EPS supports the access of HeNB, and HeNB is a kind of small-sized, lower powered base station, is deployed in indoor places such as family and office.Closed user group (Closed Subscriber Group abbreviates CSG as) is to introduce the new ideas that propose behind the base station from home.Usually the user of an one family or an enterprises forms a closed user group, and this closed user group identifies with CSG ID.The base station from home of serving for user in this closed user group has identical CSG ID.When a closed user group was only served by a base station from home, this closed user group also can directly adopt base station from home sign (for example, BS ID) to identify.According to the gerentocratic wish of base station from home, CSG user and/or non-CSG user can distinguish different grade, and the priority difference is the service priority of its enjoyment then, and enjoying service quality can be different with class of service.

The user can be linked into the pairing base station from home of a plurality of closed user group through contracting with operator, for example, and user's office space, family etc.Therefore introduced the notion that allows the closed user Groups List.This tabulation is kept in user's the user data server of terminal and network side.

The use pattern of base station from home is divided into three kinds: closed mode, mixed mode and open mode.When the family expenses base station is closed mode, have only the affiliated CSG contracted user of this base station from home can insert this base station and enjoy the business that the base station provides.When the family expenses base station was open mode, any contracted user of operator can insert this base station, and the base station from home of this moment is equal to macro base station to be used.When the family expenses base station is mixed mode; Same any contracted user of operator of permission or roamer insert use; But will be according to user's different rank of data separation of signatory CSG whether; The user who that is to say signatory this CSG has higher service priority when using the mixed type base station from home, enjoy better service quality and class of service.

When the user carried out the initialization access, the closed user group that the user data server of network side can insert the permission that the user contracts sent to the Mobility Management Entity of core net.The core network mobility management entity can utilize this information that UE is carried out access control.If UE is from undelegated closed mode base station from home visit core net, core net can be refused such user's access so.

HeNB (claims that also broadband access (Broadband Access, BBF)) inserts the core net of EPS through the fixed network circuit of renting usually.In order to ensure the safety of access, to introduce security gateway (Security Gateway abbreviates SeGW as) in the core net and shield, the data between HeNB and the SeGW will adopt IPSec to encapsulate.HeNB can be directly connected to the MME and the S-GW of core net through the ipsec tunnel that HeNB and SeGW set up, and also can be connected to MME and S-GW (being that HeNB GW is optional) through HeNB GW in EPS again.Simultaneously, in order to realize that HeNB is managed, introduced base station from home management system (Home eNodeB Management System abbreviates HeMS as) network element.

Because the QoS of the fixed network circuit that HeNB inserts normally receives owner and the fixed network operator's of HeNB signatory restriction.Therefore, when the common HeNB of 3GPP UE inserted 3GPP core net access service, required QoS can not surpass the QoS that contracts of the fixed network circuit that the fixed network operator can provide.Otherwise the QoS of UE access service will can not get guarantee, particularly guaranteed bandwidth (GuaranteedBitrate abbreviates GBR as).Therefore, for the 3GPP network, the QoS aggregate demand that must control the Operational Visit of all UE that insert through HeNB is no more than the signatory QoS guarantee of fixed network circuit that this HeNB inserts.

In addition, UMTS (Universal Mobile Telecommunications System abbreviates UMTS as) is also supported the access of Home node base station HNB (Home NodeB).

Under the situation of family expenses base station, must consider that a plurality of base station from home (for example, HeNB, HNB) insert the scene of 3GPP core net through a signatory fixed network circuit through signatory fixed network circuit access.At this moment; For the 3GPP network; The QoS aggregate demand that must control the Operational Visit of all subscriber equipmenies (User Equipment abbreviates UE as) that insert through these a plurality of base station from home is no more than the signatory QoS guarantee of the same fixed network circuit of these a plurality of base station from home accesses.

At present, a kind of framework that is used for the control of base station from home access strategy has been proposed, as shown in Figure 2.H (e) HB Policy Function (base station from home policing feature) and H (e) NB subsystem (comprising H (e) NBGW and SeGW) interface, and base station from home inserted carry out policy control.Yet prior art only provides a rough framework, and how carrying out policy control still is a problem to be solved.
