Description

A kind of CSG cell switching method, equipment and system
Technical field
The present invention relates to communication technical field, relate in particular to a kind of closed user group (Closed Subscriber Group, CSG) cell switching method, equipment and system.
Background technology
The CSG function can be implemented as the Member Users higher access grade and service rate faster is provided, and can also realize the special charge mode based on the CSG sub-district.When subscriber equipment (User Equipment, UE) signatory become the Member Users of some CSG sub-district after, can obtain higher access grade and the service rate of Geng Gao.A UE may contract simultaneously and become a plurality of public land mobile networks (Public Land Mobile Network, CSG member PLMN).
Home eNodeB (Home Node B, HNB), and the Home eNodeB of evolution (Home evolved Node B, HeNB) be a kind of low-power small base station, it is interior for the user provides higher speed to can be implemented in less coverage, also can solve the covering problem that signal is propagated relatively poor place for operator.The typical application scene comprises family and enterprise.Fig. 1 is long-term evolution upgrading (Long Term Evolution Advanced, LTE-A) network architecture behind system's introducing HeNB, HeNB can directly link to each other with core net, also can pass through agent node---the femto gateway (Home evolved Node B Gateway, HeNB GW) of evolution is connected to core net.Can set up X2 interface between the HeNB.
There is a CSG sign (ID) each CSG sub-district, and subscriber equipment can obtain CSG ID and the mode of operation that this sub-district is supported by the system information of air interface broadcasting.Support the sub-district of CSG function that two kinds of mode of operations can be arranged: closed (Closed) pattern and mixing (Hybrid) pattern.The CSG sub-district of closed mode only allowed the to contract user of this CSG ID inserts, the CSG sub-district of mixed mode (also can be called Hybrid cell) all allows to insert for contracted user and non-contracted user, only for the contracted user can provide higher access grade, and service rate etc. faster.HNB and HeNB are the base stations of typically realizing the CSG function.Technologically speaking, the base station of other types, for example: (Relay Node RN) can realize the CSG function for the base station of evolution (eNB), via node.
The CSG sub-district if UE has contracted, UE and home subscriber servers (Home Subscriber Server can preserve a CSG white list in HSS), content be PLMN ID and under this PLMN signatory CSG ID.When UE searches a CSG sub-district, judge according to the CSG white list whether oneself can insert this CSG sub-district.As UE the time to network registry, HSS can with the user the signatory CSG cell information of the PLMN of current registration send to UE the service Mobility Management Entity (Mobility Management Entity, MME).Referring to Fig. 2, comprise the CSG subscription data in renewal position response (Update Location Answer) message.The CSG subscription data comprises CSG ID, out-of-service time, or the like.When UE inserted the CSG sub-district, whether the MME checking allowed UE to insert this CSG sub-district.
Referring to Fig. 3, when the UE that is in connected state belonged to the following CSG member sub-district of current registration PLMN near one, UE sent near indicating (Proximity Indicator) message to serving BS, tells serving BS with the frequency information of this sub-district.Afterwards, serving BS can send to UE the measurement of this frequency is disposed, allow UE read this system information of subdistricts, and general's important information wherein, physical-layer cell identifier (Physical Cell Identifier for example, PCI), EUTRAN cellular global identity (EUTRAN Cell Global Identifier, ECGI), CSG ID, member condition (being used to indicate whether UE is the Member Users of CSG sub-district) or the like, reporting serving BS, is UE select target sub-district thereby be convenient to serving BS.Before UE sent near Indication message, the base station need control (Radio Resource Control RRC) connects whether indication UE activates near deixis in the reconfiguration message at Radio Resource.When base station activation near deixis after, UE just can send near Indication message to serving BS when satisfying report condition.
Flow process when UE carries out the X2 interface switching as shown in Figure 4.Source base station (Source eNB) carries out switch decision according to the measurement result of UE, selects suitable Target cell, sends handoff request message to target BS (Target eNB).Target BS returns acknowledge message to source base station after being the UE reserved resource, and generates switching command, issues UE by source base station.UE receives that setting up RRC with Target cell behind the switching command is connected, and returns RRC to target BS and connects to reshuffle and finish message.Then, target BS upgrades the positional information of UE to MME transmit path conversion request message, and conversion downlink data transmission path.At last, target BS notification source base station discharges the air interface resource of UE.
When cell-of-origin and Target cell all are the CSG sub-districts, and when having identical CSG ID, if Target cell is supported registration PLMN or the of equal value PLMN of UE in the cell-of-origin, UE can carry out the switching of X2 interface between these two sub-districts so.Otherwise, can only carry out the switching of S1 interface.
Flow process when UE carries out the switching of S1 interface as shown in Figure 5.Source base station carries out switch decision according to the measurement result of UE, selects suitable Target cell, sends handoff request message to the MME of UE (being source MME (Source MME)).Source MME finds target MME (Target MME) according to the sign of Target cell, and target MME sends handoff request to target BS.After target BS was the UE reserved resource, MME returned switching request acknowledgement message to target, and generated switching command, issued UE by source MME and source base station.UE receives that setting up RRC with Target cell behind the switching command is connected, and returns RRC to target BS and connects to reshuffle and finish message.Target BS sends handoff notification message to MME then, upgrades the positional information of UE, and conversion downlink data transmission path.At last, target MME notice source discharges the resource of UE.
When Target cell was the CSG sub-district, source (may be eNB, HeNB, RN etc.) was placed on handoff request (Handover Required) lining with the CSG ID of Target cell and issues source MME.Source MME checks that whether this CSG ID is the member sub-district under the current registration of the UE PLMN.If then continue to carry out the S1 interface switching flow of back, otherwise refuse this switching.When Target cell was the Hybrid sub-district, source MME judged the whether Member Users of this target Hybrid sub-district of UE, and judged result (" member " or " non-member ") is passed to target MME; Target MME passes to target eNB to CSG ID and member condition by handoff request (Handover Request).
Figure 6 shows that UE contextual modifications process, this process is used for revising the context of having set up for UE, comprises revising safe key, CSG member condition or the like.When MME has enabled new root key (K ASME), or the CSG member condition of UE is when changing etc., and MME can initiate UE contextual modifications process.
When the Serving cell of UE is the CSG sub-district of closed mode, when eNB knows that by UE contextual modifications request (UE Context Modification Request) message the CSG member condition of UE changes (becoming non-member) from the member, UE can be switched to other sub-districts, or discharge the connection of UE.
When the Serving cell of UE is the Hybrid sub-district, eNB knows that by UE Context Modification Request message the CSG member condition (membership status) of UE (becomes non-member from the member when changing, or become the member from non-member), be the UE service according to the member condition after changing.
Yet, prior art is owing to UE only reports near indication at the PLMN of current registration PLMN and equivalence tabulation (Equivalent PLMN list, hereinafter to be referred as EPLMN list) under CSG member sub-district, so the serving BS of UE can only know which CSG sub-district is the signatory member sub-district of UE under these PLMN.This will cause the serving BS of UE UE can only be switched to CSG member sub-district under these PLMN.When UE had contracted the CSG member sub-district of a plurality of operators, UE may be different in the signatory CSG information of each operator, and the PLMN ID of possible some signatory operator does not appear on the EPLMN list.When UE near the CSG member sub-district under unregistered operator, but the PLMN ID of this CSG member sub-district correspondence is not in EPLMN list, causing UE not report this CSG member sub-district to network side also is CSG member sub-district, therefore the serving BS of UE can not switch to UE this CSG member sub-district, thereby influences member's treatment that UE enjoys this CSG member sub-district.

Provide the explanation of several specific embodiments below.
Embodiment one: X2 HO
Whether base station configuration UE activates to go up at other PLMN (promptly except the PLMN of the current registration of UE and the PLMN the PLMN among the EPLMN list) is realized near deixis.
Activating under the prerequisite that realizes on other PLMN near deixis, as UE during near a sub-district that is arranged in the CSG white list, promptly enter the coverage of this CSG sub-district, when the signal strength signal intensity of this CSG sub-district reaches default threshold value, UE sends near Indication message to serving BS, wherein carry the frequency of the PLMN of this CSG sub-district, and can further carry PLMN ID.
Wherein, UE is during near target CS G sub-district, because UE knows ID and the EPLMN list of the PLMN of current registration, so PLMN ID according to the CSG ID correspondence of target CS G sub-district, can determine whether target CS G sub-district is the CSG sub-district under other PLMN, if target CS G sub-district is the CSG sub-district under other PLMN, and determines to have activated and on other PLMN, realize then sending near Indication message to serving BS near deixis.The technical scheme that the following adopted embodiment of the invention provides realizes this UE is switched to target CS G sub-district.If target CS G sub-district is CSG sub-district under the registered PLMN or the CSG sub-district under the EPLMN list, then adopt prior art that this UE is switched to target CS G sub-district.
Whether the ID of PLMN that judges Target cell is in the roaming restricted list of UE, if then this sub-district is not measured; Otherwise the serving BS of UE sends the measurement configuration information that this CSG sub-district is measured to UE, comprising the frequency of PLMN, measurement clearance or the like.
UE measures this CSG sub-district according to the measurement configuration information that serving BS sends, and then the information such as PCI that record is sent to serving BS.
If serving BS can be determined a CSG sub-district according to the PCI that UE reports is unique, so the base station with this CSG sub-district as one of handover candidate cells.Otherwise serving BS notice UE reads the information such as ECGI of this PCI correspondence, and at this moment, UE need report information such as ECGI, PLMN ID, CSG ID, the member condition of the CSG sub-district of this PCI correspondence in measuring reporting message.
Above step makes the source base station of UE can determine target CS G sub-district, comprises information such as the PLMN that determines target CS G sub-district, base station.
Then, if the serving BS of UE (source base station just) decision switches to target CS G sub-district with UE, then send handoff request to target BS.Source base station is given target BS with ID (also being the PLMN ID that is arranged in the CSG white list of the UE) indication of the PLMN of target CS G sub-district in this message.When Target cell was the Hybrid sub-district, source base station added " member condition " information in this message, and promptly notification target base station UE is the Member Users of target CS G sub-district, and described " member condition " information is used to indicate whether UE is the Member Users of Target cell.
Target BS returns switching request acknowledgement message and gives source base station.
Source base station sends switching command (being that RRC connects reconfiguration message) to UE.
UE reshuffles to target BS transmission RRC connection and finishes message.
Target BS is to the MME of UE transmit path exchange request (Path Switch Request) message, and the PLMN ID (being the PLMN ID of Target cell) that current UE is registered is notified to MME.
MME confirms (Path Switch Request Acknowledge) message to target BS return path exchange request.
Target BS sends the UE context to source base station and discharges (UE Context Release) message.
So far, finish the operation that UE is switched to target CS G sub-district.
After switching is finished, UE can carry out tracing section updating (Tracking Area Update, TAU) process, the ID of the registration PLMN (being the PLMN of the current CSG sub-district that switches to) that MME is current with UE issues HSS, and HSS searches the CSG subscription data of this PLMN ID correspondence, if find, then UE is issued MME at the CSG of this PLMN subscription data, otherwise, other data of this PLMN ID correspondence are issued MME, wherein there is not the CSG subscription data.MME judges according to the CSG subscription data of receiving whether the current CSG sub-district of UE allows UE to insert, particularly:
If the CSG sub-district that the current CSG sub-district that switches to of UE is a closed mode, and UE is member's (being the ID that the CSG subscription data comprises the CSG sub-district that UE is current) of this sub-district, then as shown in Figure 8, MME sends TAU to UE and accepts (TAU Accept) message; Otherwise, MME can:
As shown in Figure 9, refuse this TAU, and discharge the connection of UE;
Perhaps, as shown in figure 10, MME sends TAU Accept message to UE.Subsequently, MME initiates UE contextual modifications process to the serving BS of UE, and indication UE is " the non-member " of this CSG sub-district.Follow-up, discharge the connection of UE by the serving BS of UE.
Perhaps, MME be " non-member " by indication UE in the Downlink NAS Transport message of carrying TAU Accept message on the S1 interface, that is to say, the latter two steps among Figure 10 need not execution.Follow-up, discharge the connection of UE by the serving BS of UE, flow process shown in Figure 6 is carried out in the base station.
If the current CSG sub-district that switches to of UE is the Hybrid sub-district, and UE is member's (being the ID that the CSG subscription data comprises the CSG sub-district that UE is current) of this sub-district, and then as shown in Figure 8, MME sends TAU Accept message to UE; Otherwise as shown in figure 10, MME is after UE sends TAU Accept message, and MME initiates UE contextual modifications process to the serving BS of UE, and indication UE is " the non-member " of this CSG sub-district, but the serving BS of UE need not to discharge the connection of this UE.
In like manner, the purpose that latter two steps realizes among Figure 10 also can be finished for " non-member " by indication UE in the Downlink NAS Transport message of carrying TAUAccept message on the S1 interface, thereby no longer carry out this two steps, flow process shown in Figure 6 is carried out in the base station afterwards.
Need to prove that some step among the embodiment one can be omitted, or insert other processes in the middle of some step.Embodiment one provides a kind of more excellent switching flow.For example, the first step can be omitted, and can carry out omitting standardized layoutprocedure near indication on other PLMN by predesignating UE.
