Present mobile communication more and more trends towards as user provides the multimedia service of high rate data transmission, as shown in Figure 1, is the system architecture diagram of System Architecture Evolution (SAE).Wherein:

Subscriber equipment (UE) 101 is used to the terminal equipment receiving data.Evolved universal terrestrial radio access network (E-UTRAN) 102 is Radio Access Networks, comprising the macro base station (eNodeB/NodeB) providing access of radio network interface for UE.Mobile management entity (MME) 103 is in charge of the mobile context of UE, session context and security information.Gateway (SGW) 104 mainly provides the function of user plane, MME103 and SGW104 may be in Same Physical entity.Grouped data network gateway (PGW) 105 is responsible for the function such as charging, Lawful Interception, also can be in Same Physical entity with SGW104."Policy and Charging Rules Function entity (PCRF) 106 provides service quality (QoS) strategy and charging criterion.Universal grouping wireless business supporting node (SGSN) 108 is for the transmission of data provides the apparatus for network node of route in universal mobile telecommunications system (UMTS).Home subscriber server (HSS) 109 is local ownership subsystems of UE, and responsible preservation comprises the user profile such as packet data content of the current location of subscriber equipment, the address of service node, user security information, subscriber equipment.

3GPP proposes at version 12 (Rel-12) demand that small-cell (small cell) strengthens, the target scene that small-cell strengthens comprises: the scene having macrocell to cover and the scene not having macrocell to cover, indoor and outdoors, the enhancing of ideal and imperfect backhaul, as shown in Figure 2.

The scene covered there being macrocell, proposes the technology can applying carrier aggregation between different base station, and it is UE service that macrocell and small-cell can be operated in different frequency ranges simultaneously.The framework of the technology of the carrier aggregation between application different base station has multiple, at chain of command, mainly controlled UE to carry by MeNB and be based upon macrocell that MeNB (Master eNB: dominant base) serves and cover on small-cell that lower SeNB (Secondary eNB: prothetic group station) serves, reach enhancing capacity, improve the effect of UE speed.

At present, Home eNodeB (HeNB) is that the deployment of small-cell one of is selected, and carrying can be based upon on the small-cell of HeNB service by MeNB according to demand.In the coverage of macrocell, multiple small-cell can be disposed, multiple HeNB.But the CSG belonging to HeNB/ small-cell is (Closed Subscriber Group, closed user group) may be different, it is the small-cell closed (Closed) or mix (Hybrid) to community access module, the UE of non-CSG member does not allow access, or the QoS setting up carrying is different.Under the framework that signaling plane wireless access network (RAN) separates, determine whether carrying is based upon on small-cell by MeNB, and how MeNB understands the member of the CSG of UE whether belonging to small-cell, does not also have rational solution at present, there is following particular problem:

1) when UE carrying can be based upon on the small-cell that SeNB provides by UE attachment or incision MeNB, MeNB, if small-cell is CSG cell, signaling core net is not had to carry out CSG authentication according to the CSG subscription information of UE to UE at present.

2) as UE attachment or incision MeNB, UE carrying can be based upon on the small-cell that SeNB provides by MeNB, if small-cell is CSG cell and community access module is closed mode, MeNB cannot verify whether UE is CSG member, the carrying of the UE not being CSG member may be established on the small-cell of closed mode.

3) as UE attachment or incision MeNB, UE carrying can be based upon on the small-cell that SeNB provides by MeNB, if small-cell is CSG cell and community access module is promiscuous mode, MeNB cannot verify whether UE is CSG member, cannot be respectively the resource that CSG member or non-CSG member distribute different QoS grade.

4) to the UE carrying setting up or transfer to CSG small-cell, core net does not also know the resource which occupies CSG, and core net cannot support the charging based on CSG.

5) when occurring to switch between MeNB, source eNB does not know that the SeNB community under target MeNB is CSG cell, X2 will be triggered switch, UE can be established on CSG small-cell when receiving handover request by target MeNB, but does not have signaling core net to carry out authentication according to the CSG subscription information of UE to UE at present.MeNB does not know whether UE allows to access CSG cell.

Embodiment

For making the object of the application, technical scheme and advantage clearly understand, to develop simultaneously embodiment referring to accompanying drawing, the application is described in further detail.

Fig. 3 is that a kind of support of the present invention carries the method schematic diagram set up.The method comprises the process of MeNB side and the process of MME side, and in the following description, two-part process combination be described, shown in Fig. 3, method comprises the following steps:

The CSG mark that under step 301:MeNB sends the lower all SeNB of described MeNB covering to MME, community is supported, or under SeNB, the CSG of community, UE place identifies.

Further, MeNB can be sent as identifying at the PLMN of prothetic group station cell serves in UE of UE selection to MME simultaneously.

Further, when MeNB supports CSG, the CSG mark of community, UE place under the CSG mark that MeNB can indicate community under MeNB to support or MeNB.

Community, described UE place can have the community of carrying or MeNB to determine the community of UE under its coverage according to the measurement report of UE for described UE sets up.Such as: suppose according to the measurement report of UE, MeNB recognizes that the wireless signal strength that UE measures in neighbor cell 1 is enough to access, so, can think that the CSG mark of community 1 is exactly the CSG mark of community, UE place.

Further, MeNB, while obtaining the CSG mark supported community under SeNB, when this community is for mixing community, can also obtain the community access module of community: mix (Hybrid).

Because SeNB directly may access MeNB, also can access MeNB by SeNB GW, therefore, may have direct interface between MeNB and SeNB, the interface between also may needing by SeNB GW and SeNB carry out information interaction.Under the SeNB that above-mentioned MeNB obtains community support CSG mark and community access module, can be that MeNB directly obtains from the interface between SeNB, also can be by SeNB GW between interface obtain.

When accessing new SeNB under SeNB GW, and when the CSG that under new SeNB, community is supported is different from the CSG supported community under original SeNB, SeNB GW is identified by new CSG and/or community access module updates to MeNB.

Further, by the information interaction of MeNB and neighbours eNB (MeNB or general eNB), the CSG mark that MeNB is covered lower all SeNB supports by MeNB is informed neighbours eNB or is switched instruction to neighbours eNB transmission CSG, this CSG switches instruction and represents when needs carry out taking MeNB as the switching of target BS, carries out S1 switching.

Further, when UE cuts target MeNB from source MeNB or general eNB, if target MeNB or its cover the CSG supported lower SeNB community identify the CSG supported the SeNB community under covering from source MeNB or its identify exist different, or CSG mark constant but service PLMN change time, then source MeNB or general eNB triggers S1 switching, notice MME carries out CSG authentication to UE, and the CSG mark that under target MeNB or its being covered lower all SeNB, community is supported informs MME; Or source MeNB or general eNB switches instruction according to CSG and triggers S1 switching, and notice MME carries out CSG authentication to UE.

Step 302:MME carries out CSG authentication to UE, sends the access authenticating result of UE in the community of correspondence, can also send UE mixing the CSG member condition of community to MeNB to MeNB.

Further, when (target) MeNB does not support CSG, and it covers lower SeNB when supporting CSG, and CSG authentication does not allow access, and MME sends to (target) MeNB the instruction that CSG authentication does not allow access.

Further, if MeNB sends CSG mark to MME when UE attachment or location updating or service request, described CSG mark is one or more marks, so:

When the access authenticating result of the MeNB community of UE attachment is not for allowing to access, MME returns attachment refusal to UE;

When the community that CSG mark is corresponding is the MeNB community of UE and CSG access authenticating result is when allowing the MeNB community of access or UE not support CSG, MME to MeNB return UE to identify at each CSG corresponding to the access authenticating result of community;

Wherein, if when the community of CSG mark instruction is for mixing community and allowing UE to access, then returns UE and mixing the CSG member condition of community, recessive instruction UE accesses for allowing in the described CSG access authenticating result mixing community; Or the access authenticating result mixing community comprises and allows the instruction of access and UE mixing the CSG member condition of community: member or non-member.

If MeNB sends CSG mark to MME when S1 switches, described CSG mark is one or more marks, so:

When the CSG access authenticating result of the target MeNB that S1 switches is not for allowing to access, MME returns and switches refusal;

When the CSG access authenticating result of the target MeNB of S1 switching is for allowing to access, MME returns the access authenticating result of the community of UE corresponding to each CSG mark to the target MeNB switched;

Further, if the community corresponding to CSG mark for mixing community, and UE in the described access authenticating result mixing community for passing through, MME returns UE in the described CSG member condition mixing community to MeNB: member or non-member.

The CSG authenticating result of the UE that step 303:MeNB sends according to MME, determines whether UE carrying is based upon, moves into or shifts out corresponding community.

Preferably, MeNB can receive the access authenticating result of closing or mix community of UE corresponding to each CSG mark that MME returns, and wherein, the access authenticating result mixing community comprises UE further and mixing the CSG member condition of community: member or non-member.

Further, it is obstructed out-of-date that the access authenticating result of community corresponding to identifying at each CSG as UE is, UE carrying can not be based upon the community corresponding to arbitrary CSG mark by MeNB, and when the community corresponding to CSG mark has UE carrying, UE carrying need be shifted out from this community by MeNB.

Further, when CSG mark corresponding to SeNB community be mix community and the access authenticating result of UE in this SeNB community for by time, MeNB can by UE carrying be based upon described SeNB community; For the UE carrying under described SeNB community, MeNB can be respectively member UE and non-member UE based on member and non-member resource allocation policy further and set up UE carrying.

Further, when CSG mark corresponding to SeNB community be closed community and the access authenticating result of UE in described SeNB community for passing through time, UE carrying can be based upon described SeNB community by MeNB, when there being the user plane bearer of non-member UE under the SeNB community corresponding to described CSG mark, the user plane bearer of described UE shifts out from the SeNB community corresponding to described CSG mark by MeNB.

Further, when the CSG member condition of UE becomes non-member, to the SeNB community supporting described CSG mark, if this SeNB community is for closing community, UE carrying is shifted out from described SeNB community by MeNB; If this SeNB community is for mixing community, MeNB can change the QoS of described UE carrying based on member and non-member resource allocation policy.

Further, when the CSG member condition of UE becomes member, to the SeNB community supporting described CSG mark, if this SeNB community is for closing community, UE carrying can be established to described SeNB community by MeNB; If this SeNB community is for mixing community, MeNB can change the QoS of described UE carrying based on member and non-member resource allocation policy.

Further, when the SeNB community corresponding to CSG mark is set up or transferred to UE carrying by MeNB, the CSG mark supported SeNB community informs MME.

Step 304:MME receives the CSG mark setting up UE carrying that MeNB reports, and MME carries out charging based on the corresponding Freight Basis of this CSG to UE.

Step 305: when UE close or mix community CSG member condition change time, the CSG member condition of the UE of change is informed the MeNB at SeNB place by MME, instruction CSG mark and UE change CSG member condition.

Below by several preferred embodiment, technical scheme is further elaborated.

Embodiment one:

The present invention supports the schematic diagram of the embodiment of the method one carrying foundation as shown in Figure 4.This embodiment is applicable to SeNB and MeNB direct interface, and when UE adheres to or in position updating process, carrying is set up, MeNB will carry the scene being established to the SeNB community supporting CSG, and wherein, SeNB1 and SeNB2 is two SeNB under MeNB.Shown in Fig. 4, method comprises the following steps:

Step 401:MeNB passes through OAM, or in the process of MeNB and SeNB interface foundation, or in eNB config update process, MeNB obtains the CSG mark and/or community access module supported SeNB community.In UE attachment or position updating process, MeNB can be covered the CSG mark supported lower SeNB community by two kinds of modes and report MME by MeNB, is respectively step 403 and step 406.

Step 402:UE initiates attachment request or position updating request to MeNB.

When step 403:MeNB forwards attachment request or the position updating request of UE by initial UE message or up NAS transmission message to MME, the CSG that under being covered by MeNB, SeNB community is supported simultaneously identifies and reports MME.Further, MeNB can transmit message by initial UE message or up NAS simultaneously be sent as identifying at the PLMN of prothetic group station cell serves in UE of UE selection to MME.

Step 404:MME carries out authentication according to the CSG subscription information (CSG list allowed under different PLMN) of UE to UE, when described CSG mark be full the CSG mark of SeNB community or the CSG of MeNB community identify access authentication by time, set up request or descending NAS by initial context and transmit message to send CSG authenticating result from UE to MeNB: permission or do not allow; That passes through access authentication mixes community, returns the CSG member condition of UE, and the CSG member condition returned can allow to mix community described in access by recessive instruction UE, now can not return CSG authenticating result.

UE may be different in the same CSG access authenticating result of different PLMN and the member condition of CSG, when receiving the prothetic group station cell serves of MeNB transmission in step 403 when the PLMN mark of UE, the access authenticating result of UE and/or the member condition of CSG under MME sends described PLMN to MeNB.

Step 405:MeNB forwards attachment to UE and accepts or location updating acceptance.

Step 406: in the process that S1 interface is set up between MeNB and MME, MME obtains MeNB and covers the CSG mark and/or community access module supported lower SeNB community.Further, MME can obtain MeNB is simultaneously identifying at the PLMN of prothetic group station cell serves in UE of UE selection.

Step 407:UE initiates attachment request or position updating request to MeNB.

Step 408:MeNB passes through initial UE message or up NAS transmits message forwards attachment request from UE to MME or position updating request.Further, MeNB can transmit message by initial UE message or up NAS simultaneously be sent as identifying at the PLMN of prothetic group station cell serves in UE of UE selection to MME.

Step 409:MME carries out authentication according to the CSG subscription information (CSG list allowed under different PLMN) of UE to UE, when described CSG mark be full the CSG mark of SeNB community or the CSG of MeNB community identify access authentication by time, set up request by initial context or descending NAS transmits the CSG authenticating result of message to MeNB transmission UE; That passes through access authentication mixes community, returns the CSG member condition of UE.The CSG member condition returned can allow to mix community described in access by recessive instruction UE, now can not return CSG authenticating result.

UE may be different in the same CSG access authenticating result of different PLMN and the member condition of CSG, when receiving the prothetic group station cell serves of MeNB transmission in step 408 when the PLMN mark of UE, the access authenticating result of UE and/or the member condition of CSG under MME sends described PLMN to MeNB.

Step 410:MeNB forwards attachment to UE and accepts or location updating acceptance.

Step 411:MeNB receives the CSG authenticating result of the UE that MME sends.That passes through access authentication mixes community, MeNB receives the CSG member condition of UE, to the CSG mark that access authentication is passed through, UE carrying can be based upon on the SeNB community of support CSG mark by MeNB, and MeNB sends newly-increased cell request or bearing activation request to SeNB.

Step 412:SeNB returns the response of newly-increased community or bearing activation response to MeNB.

Step 413:MeNB sends initial context to MME and sets up response, and instruction UE carries the CSG mark at place.

Step 414:MME initiates E-RAB to MeNB and sets up request.

Step 415: the CSG mark passed through access authentication, UE carrying can be based upon on the SeNB community of support CSG mark by MeNB, and MeNB sends newly-increased cell request or bearing activation request to SeNB.

Step 416:SeNB sends the response of newly-increased community or bearing activation response to MeNB.

Step 417:MeNB sends E-RAB to MME and sets up response, and instruction UE carries the CSG mark at place.

Step 418: the CSG mark passed through authentication, UE carrying can be based upon on the SeNB community of support CSG mark by MeNB, and MeNB sends newly-increased cell request or bearing activation request to SeNB.

Step 419: target SeNB sends the response of newly-increased community or bearing activation response to MeNB.

Step 420:MeNB is to MME transmit path handover request or amendment carrying request, and instruction UE carries the CSG mark at place.MME can carry out charging based on CSG mark to UE.

Step 421:MME is to MeNB return path Handover Request Acknowledge or amendment carrying response.

Step 422:MeNB releasing resource, sends to source SeNB and deletes cell request or load bearing deactivation request.

Step 423: source SeNB returns to MeNB and deletes community response or load bearing deactivation response.

Step 424: when UE is closing or mixing the CSG member condition change in community, MME sends UE context modification request to MeNB, the CSG member condition that instruction CSG and UE changes.

Step 425:MeNB returns the response of UE contextual modifications to MME.
