Description
Technical field
The present invention relates to communication technical field, relate in particular to and a kind of terminal is carried out system of access control and method.
Background technology
Home eNodeB (HNB, Home NodeB) is a kind of small-sized, lower powered base station, be deployed in indoor places such as family and office, main effect is higher service rate to be provided and to reduce the needed expense of use high rate services to the user, has remedied the deficiency that existing distributed cellular radio communication system covers simultaneously.The advantage of Home eNodeB is economical, convenient, low-power output, plug and play etc.
The Home eNodeB user is by Home eNodeB Access Network (HNB AN, Home NodeB AccessNetwork,) be connected to core net, Fig. 1 is Long Term Evolution (LTE, Long Term Evolution) the home base station network schematic layout pattern in the system, as shown in Figure 1, HNB AN is by Home eNodeB and the common composition of femto gateway (Home NodeB Gateway, HNB GW).The function that HNB GW mainly carries out comprises: verify the fail safe of Home eNodeB, the registration of handling Home eNodeB and access control, Home eNodeB is carried out operation maintenance management, disposes and control Home eNodeB, is responsible for the data between exchcange core net and the Home eNodeB according to Carrier Requirements.Fig. 2 is universal mobile telecommunications system (UMTS, Universal Mobile Telecommunications System) the home base station network schematic layout pattern in, as shown in Figure 2, in the UMTS network, Home eNodeB must be linked in the core net by femto gateway, wherein the interface between Home eNodeB and the femto gateway is the Iuh interface, and femto gateway is the Iu interface to the interface between the core net.Macro base station is connected with core net by radio network controller, and the interface between macro base station and the radio network controller is an Iub interface.And also can have direct interface between the radio network controller, be called the Iur interface.As shown in Figure 1, for follow-up evolved Home eNodeB (HeNB, Home eNodeB), can not be directly connected to core net by femto gateway yet.Interface between Home eNodeB and the core net represents that with S1 if femto gateway exists, the interface between Home eNodeB and femto gateway, femto gateway and the core net is the S1 interface.Can use the direct interface X2 interface to connect between the macro base station.The ground that is without loss of generality in subsequent descriptions uses Home eNodeB to be used as the general designation of evolved Home eNodeB in Home eNodeB under the UMTS system and the LTE system.
Because Home eNodeB is a kind of of macro base station (NodeB or eNodeB), its dedicated resources as private user is deployed in special field such as family, company or school, and some cell set that Home eNodeB covers become family base station overlay area.The access module of Home eNodeB has three kinds, is respectively: open mode, closed mode and mixed mode.The Home eNodeB of open mode allows all users to insert; The Home eNodeB of closed mode only allows to insert through the user who authorizes, and as users such as the kinsfolk that authorizes, members of community, these are called closed user group (CSG, Closed SubscriberGroup) through the users that authorize; The Home eNodeB of mixed mode allows all users to insert, but enjoys the power of preferential or preferential access for the user who belongs to this CSG.Accordingly, the Home eNodeB affiliated subdistrict is called the CSG sub-district.
Subscriber equipment (UE, signatory white tabulation (white list or Allow CSG List) about CSG is arranged among USIM User Equipment) (3G system user identification card), if white tabulation is empty, show that this subscriber equipment does not belong to any closed user group; If white tabulation has effective value, show that this subscriber equipment is the authorized user of these listed CSG sub-districts.For the subscriber equipment that has white tabulation, can reside in the CSG sub-district that is authorized to, can not be resident for the CSG sub-district of the closed mode that does not have to authorize.White list records subscriber equipment allow the CSG cell ID (CSG ID) that inserts, this white tabulation is also preserved at the customer data base of core net simultaneously.When the UE that has white tabulation wishes to reside in the CSG sub-district, Home eNodeB reports core net with the CSG ID under the sub-district, checks by core net whether the resident sub-district of UE desire allows the access of UE, for the CSG sub-district of closed mode, only allow authorized user to insert, unauthorized user is forbidden inserting; For the CSG sub-district of mixed mode, authorized user is enjoyed preferential or preferential access power, and (Access Control AC) is called as access control based on CSG in this access control.Home eNodeB under the open mode is the same with common macro base station, allows all legal users to insert.
For the CSG sub-district, global cell identity (CGI, Cell Global Identifier) is not only arranged, also have the CSG cell ID.The CSG sub-district that has different global cell identities can corresponding same CSG ID.When the family base station powered on registration, femto gateway can obtain CSGID, CGI and the access module of this Home eNodeB.When the family base station directly linked to each other with core net, core net can obtain CSG ID, CGI and the access module of these direct-connected Home eNodeB.Non-Home eNodeB is commonly referred to as base station or macro base station, and affiliated subdistrict is called macrocell.
Owing to the mobility of UE, inevitably need move to the coverage of another sub-district from a sub-district, in order to guarantee professional continuity, therefore need network assistance to switch.Wherein being called Inbound by the switching of macrocell between CSG sub-district or CSG sub-district switches.In Inbound switches because the specific properties of CSG sub-district, need whether be that the authorized user of Target cell is judged to UE, whether in addition owing to exist direct interface still not have final conclusion between macrocell and CSG sub-district or the CSG sub-district, so the switching between current I nbound switching flow and the macrocell is distinguished to some extent.Be without loss of generality, the current flow process that Inbound switches in the LTE system is described below substantially as shown in Figure 3 substantially:
UE sends to measure to source base station and reports;
Source base station reports the Target cell of judging that the UE needs switch according to the measurement of UE, initiate to switch requirement to core net, have the contextual information of UE in the message, and the information of Target cell, such as the cell ID (cell ID) of Target cell, the CSG of sub-district sign (CSG ID) etc.;
Core net is done access control according to the information of switching the Target cell in requiring, judge whether current UE is the legal authorization user of target CS G sub-district, if this UE can insert Target cell with authorized user or unauthorized user, then flow process continues, otherwise core net is replied to switch to source base station and is prepared failed message, and handoff procedure finishes;
Core net sends handoff request message to the gateway at target Home eNodeB place, has the contextual information of this UE in the message, target cell information etc.;
The target femto gateway is done the checking of CSG according to information in the message, judges whether the CSG information of Target cell is correct;
The target femto gateway sends handoff request message to the target Home eNodeB;
The target Home eNodeB is replied handover request ack message to gateway after successfully admitting this UE;
The target femto gateway continues to send handover request ack message to core net;
Core net sends switching command message to source base station after receiving handover request ack message;
Source base station sends switching command message to UE after receiving message.
By the visible Inbound of foregoing description switch with common macrocell between switching compare, need to increase for the access control of UE with to the proof procedure of Target cell CSG information.If access control in the handoff procedure and CSG authentication failed, it is unsuccessful then may to cause this to switch, and then eNB is necessary for UE and reselects switching target small area, and this may cause the switching of UE to cross evening or signaling waste.Need to initiate blind switching if the base station is surveyed in the source in addition for certain special-purpose (such as for balanced load), be that the source is surveyed the measurement do not need UE and directly initiated switching to a certain adjacent area, this moment the source survey the base station for UE the mandate in CSG sub-district, adjacent area know nothing, therefore may cause blind handoff failure.

Step 401: the network side network element sends adjacent area access control request to core net, carries the information and the UE sign of all or part adjacent area of current service cell in this request;
In the LTE system, the network side network element can be evolution Home eNodeB or evolution femto gateway or macro base station; In the UMTS system, the network side network element can be Home eNodeB or macro base station or radio network controller.
The network side network element can be to send adjacent area access control request to core net when the first access network of this UE, also can be to send adjacent area access control request to core net when the signatory white tabulation of knowing this UE changes.
Can be that its signatory white tabulation of UE informing network side network element changes after the signatory white tabulation of UE changes, also can be that the signatory white tabulation of core net informing network side network element UE changes.
The adjacent area access control request that the network side network element sends can be a newly-increased message, the process that the S1 mouth/the Iu mouth has existed in also can multiplexing current agreement, such as passing through initial UE message (Initial UEMessage) flow process, perhaps by up direct transferring flow processs such as (Uplink NAS Transfer), core net is set up request (Initial UE Context Setup Request) process by the initial UE context after judgement, perhaps descending direct transferring (Downlink NAS Transfer) process, the message such as (Direct Transfer) that perhaps direct transfers feeds back to Current Serving BTS with response message.
If the network side network element is a Home eNodeB, and this Home eNodeB is when being connected with core net by femto gateway, and the adjacent area access control request that Home eNodeB sends is to core net by the base-station gateway transparent transmission;
If the network side network element is a macro base station and when being connected with core net by radio network controller, the adjacent area access control request that macro base station sends is to core net by the radio network controller transparent transmission;
The information of all or part adjacent area of current service cell, can be pre-configured, as disposing by operation management maintain (Operation Administration and Maintenance), or (Home nodeB Management System HMS) is configured on the Home eNodeB to pass through the Home eNodeB management system; Also can be that the network side network element obtains from the adjacent area, as (Automatic Neighborhood Relation, ANR) function is obtained automatically from the adjacent area, perhaps obtains from the adjacent area by direct interface by Automatic Neighboring Relation.
Step 402: core net is received adjacent area access control request, judge according to the information of wherein adjacent area whether this adjacent area is present in the signatory white tabulation of this UE, be to judge that then this UE is the authorized user of this adjacent area, otherwise judge that this UE is not the authorized user of this adjacent area.
Step 403: core net is returned adjacent area access control response to the network side network element, wherein carries the authorization message of UE in each adjacent area;
Core net can adopt default indication information to represent the authorization message of this UE in each adjacent area (each adjacent area refers to an access each adjacent area of carrying in the control request) herein when the network side network element returns adjacent area access control response, as can but be not limited to adopt 1 bit signalling to represent the authorization message of this UE in certain adjacent area, represent that when this signaling is 1 (or 0) this UE authorizes in this adjacent area, when this signaling is 0 (or 1), represent this UE unauthorized in this adjacent area.
If the network side network element is a Home eNodeB, and this Home eNodeB is when being connected with core net by femto gateway, and the adjacent area access control response that core net is returned is to Home eNodeB by the base-station gateway transparent transmission.If the network side network element is a macro base station and when being connected with core net by radio network controller, the adjacent area access control response that core net is returned is to macro base station by the radio network controller transparent transmission.
Step 404: after the network side network element is received adjacent area access control response message, preserve the authorization message of UE in each adjacent area.
Optionally, the adjacent area access control result that the network side network element is done, promptly UE also can pass to target side by switching command in the authorization conditions of each adjacent area in handoff procedure, the judgement foundation when target side can continue to use this information to switch as UE next time.
Core net refers to MME in the LTE system; Core net refers to CN in the UMTS system.
Below further describe the present invention by application example
Application example one is Home eNodeB (HNB) with the network side network element, and HNB is connected to example by HNB GW and core net and further specifies the present invention, concrete implementation step as shown in Figure 5:
Step 501: when the first access network of UE, HNB initiates initial UE message (Initial UE Message) to HNB GW, carry the information of all or part adjacent area of the current service cell at UE place in the message, such as the cell ID (Cell ID) of adjacent area and/or the CSG sign (CSG ID) of adjacent area etc., and the identification information of current UE.
Step 502: femto gateway HNB GW sends to core net with initial UE information (Initial UE Message).
Step 503: after core net is received this initial UE message, judge whether current UE is the authorized user of each adjacent area, judge promptly whether the CSG information of each adjacent area in the message is present in the signatory white tabulation of this UE.
Step 504: core net is replied femto gateway HNB GW with judged result by direct-sending message (Direct Transfer), have in the message whether the indication current UE is the indication information of each adjacent area authorized user, such as using true (TRUE) to represent UE is the authorized user of certain adjacent area, and representing UE with false (FALSE) is not the authorized user of certain adjacent area.
Step 505:HNB GW will cross direct-sending message (Direct Transfer) and pass through HNB, have in the message whether the indication current UE is the indication information of each adjacent area authorized user, such as using true (TRUE) to represent UE is the authorized user of certain adjacent area, and representing UE with false (FALSE) is not the authorized user of certain adjacent area.
After step 506:HNB receives this direct-sending message, can store this authorization message.When this HNB does load balancing because of the too high needs of load, can use this information to use one of the foundation of load balancing Target cell that elects.
Application example two is that evolved Home eNodeB (HeNB) is an example with the network side network element, as shown in Figure 6, may further comprise the steps:
Step 601: when UE was in connected state, variation had taken place in the signatory white tabulation of UE, and MME initiates the signatory white list update message of UE to Current Serving BTS HeNB.
Step 602:HeNB is after receiving this white list update message, initiate adjacent area access control request to MME, carry the information of all or part adjacent area of the current service cell at UE place in the request, such as the cell ID (Cell ID) of adjacent area or the CSG sign (CSG ID) of adjacent area etc., and the identification information of current service UE, such as the S1 mouth of UE sign (S1AP ID) etc.
After step 603:MME receives adjacent area access control request, judge according to the information of the adjacent area in the request whether current UE is the authorized user of each adjacent area, judge promptly whether the CSG information of each adjacent area in the message is present in the signatory white tabulation of this UE.And judged result is passed through adjacent area access control response message reply Home eNodeB HeNB, have in the message whether the indication current UE is the indication information of each adjacent area authorized user, such as using true (TRUE) to represent UE is the authorized user of certain adjacent area, and representing UE with false (FALSE) is not the authorized user of certain adjacent area.
After step 604:HeNB receives this response, can store this judgement information.When this HeNB need initiate blind cutting to this UE, can use this information with electing one of blind foundation of cutting Target cell, the sub-district that promptly preferential selection has been authorized is as Target cell, thereby improves handover success rate.
