Description
Technical field
The present invention relates to moving communicating field, the processing method and the system of approaching indication during in particular to a kind of the switching.
Background technology
In the construction of Radio Network System, indoor covering has become the most important thing of networking, rational indoor covering scheme can make network system farthest bring into play its effect on the one hand, for operator creates bigger value, also can save the networking cost of operator on the other hand greatly, the high repayment of the low input of real realization.Thus, a kind ofly be called Home eNodeB (Home eNodeB, radio reception device HeNB) arises at the historic moment.Home eNodeB is deployed in private sites uses such as family, group, company or school as the dedicated resources of private user, can various high-speed radio access services be provided and preferential on the rate is provided to the user, remedy existing distributed cellular radio communication system simultaneously and cover defect of insufficient.
The frequency resource that Home eNodeB can use operator to reserve as Home eNodeB specially also can be used the frequency resource identical with macro base station, and the sub-district under macro base station (eNB) covers is called macrocell, and the sub-district under Home eNodeB covers is called home base station cells.Home eNodeB has three kinds of access modules at present: open mode, closed mode and mixed mode, wherein, the Home eNodeB of open mode allows all users to insert, corresponding sub-district is called the home base station cells (open cell) of open mode, and this sub-district and common macrocell are as broad as long; The Home eNodeB of closed mode only allows to insert through the user who authorizes, as users such as the kinsfolk that authorizes, members of community, these have constituted a closed user group (CSG through the user's (being called for short the Member Users) who authorizes, Closed Subscriber Group), identify with CSG ID (CSGIdentity), the user allows each closed user group id of inserting, be stored in subscriber equipment (UserEquipment, abbreviate UE as) in, sub-district under the Home eNodeB of closed mode covers is called the home base station cells of closed mode, is called for short the CSG sub-district; The Home eNodeB of mixed mode also has a closed user group, the Home eNodeB of mixed mode is except the permission Member Users inserts, also allow non-Member Users to insert, but the Member Users enjoys the preferential assurance power of service quality, priority allocation power on the resource and the preferential right on the rate, corresponding sub-district is called the home base station cells (Hybrid Cell) of mixed mode.
The CSG sub-district only allows the Member Users to insert, for satisfying travelling performance good under the connected state, UE need initially insert judgement (Preliminary Access Check) to the CSG sub-district, be System information block 1 (the System Information Block1 that UE need read the CSG sub-district, SIB1), allow each CSG ID of inserting according to the user who preserves among CSG ID that broadcasts among the SIB1 and the UE, judge whether UE allows to insert this CSG sub-district.Home base station cells has a Physical Cell Identifier (Physical Cell Identity in addition, PCI) and a global cell identity (Cell Global Identifier, CGI), the limited amount of PCI (504), a large amount of deployment along with Home eNodeB, the inevitable situation that the identical PCI of two or more home base station cells uses must occur, (Public Land Mobile Network, PLMN) scope is interior unique and CGI is at public land mobile network.UE can directly obtain the PCI of home base station cells in Cell searching/measuring process, and CGI must just can obtain by reading SIB1.With the current macrocell that resides in of UE is example, if there are two or more home base station cells to use identical PCI, macrocell is received behind the PCI of the home base station cells that UE reports can't unique definite target home base station cells, for addressing the above problem, need UE to read the SIB1 of target home base station cells, obtain CGI and it is reported macrocell, thus unique definite target home base station cells.Usually network side knows which frequency is the special-purpose frequency that is exclusively used in the CSG sub-district, and network side is also known the employed PCI scope in CSG sub-district (PCI Range) on the mixing frequency.
Because Home eNodeB has mobility as the equipment of plug and play, and magnanimity is disposed, can not concern by configuring adjacent cell between macrocell and the CSG sub-district generally speaking, be that UE is the information that can not obtain adjacent C SG sub-district when macrocell switches to the CSG sub-district, UE needs real-time detection to obtain CSG ID, the CGI of CSG sub-district, the purpose that information such as TAC (Tracking Area Code, tracking area coding), PLMN just can reach switching.Simultaneously because UE has preferential or preferential right in the CSG sub-district of some mandate, therefore UE need switch to appropriate C SG sub-district as soon as possible, UE need preserve the CSG cell information of the closed mode that has inserted or visited for this reason, this part information is called footprint or fingerprint, by footprint or fingerprint, UE can be initiatively and be detected the CSG sub-district of mandate in time, and footprint or fingerprint can comprise contents such as the neighboring BS information, address of PCI, frequency, this CSG sub-district of CSG sub-district.UE need preserve the home base station cells (being Hybrid Cell) of (being the member) mixed mode of the mandate that has inserted or visited, and for non-member's Hybrid sub-district, UE does not need to preserve footprint or fingerprint information.Because the plug and play and the mobility of Home eNodeB, if variation has taken place for the PCI of home base station cells or frequency, UE still needs to detect within a certain period of time and finish switching flow.
When the UE that is in connection status enters footprint or fingerprint zone, if network side has the ability of switching to the CSG/Hybrid sub-district (network side is notified UE by dedicated signaling), UE informing network side joint is closely indicated (Proximity Indication), the frequency information and access network technology (the Radio Access Technology that in this approaching indication, comprise place, CSG/Hybrid sub-district, RAT comprises E-UTRAN or UTRAN).Network side comprises after receiving that this is near indication:
If network side does not dispose the measurement configuration (comprising measurement clearance or compact model) of place, CSG/Hybrid sub-district frequency, network side will dispose the measurement configuration (comprising measurement clearance or compact model) of described frequency for this UE; UE is according to the neighbor cell of the new described frequency of measurement allocating and measuring; If the sub-district of satisfying report condition is arranged, UE sends measurement report to network side; Network side will specify UE to read the system message of appropriate C SG/Hybrid sub-district according to measurement report; UE implements initial access control and judges (Preliminary AccessCheck) after obtaining the system message of network appointment CSG/Hybrid sub-district, and the report network side.The initial access control information that network side reports according to UE (initial access control information also is referred to as handover preparation information, i.e. handover preparation information) is implemented handover decisions.
If network side has disposed the measurement configuration of place, CSG/Hybrid sub-district frequency, network side can specify UE to read the system message of appropriate C SG/Hybrid sub-district according to measurement report; UE implements initial access control and judges (Preliminary Access Check) after obtaining the system message of network appointment CSG/Hybrid sub-district, and the report network side.Network side is implemented handover decisions according to the initial access control information that UE reports.
When UE after network side has reported approaching indication (Proximity Indication), UE can not just detect the CSG/Hybrid sub-district of the mandate that signal satisfies condition immediately, UE can not just switch to the CSG/Hybrid sub-district of mandate immediately, UE still may switch to other macrocell, after UE switches to other macrocells and cuts, need report again near indication to the sub-district (Target cell) that newly switches to, after Target cell receives that this is near indication, carry out respective handling, this method waste interface-free resources, and postponed UE to the switching of authorizing the CSG/Hybrid sub-district.

Embodiment one
In the LTE system, UE is positioned at macro base station (base station 1, be source base station in the present embodiment) jurisdiction district 1, be in connection status, current area allows to report near indication or has the ability (reportProximityConfig is set to allowed) that support is switched to closed user group cell.The source network side is that UE has disposed the measurement configuration, and UE implements measurement according to measuring configuration, reports the cell information that satisfies report condition.
As shown in Figure 3, comprising:
Step 301, sometime, UE is according to the footprint or the fingerprint information of preserving, determine CSG or Hybrid sub-district near the mandate that inserts before certain, UE reports near indication to the source network side, comprises the frequency information (frequency f 1) and the access network technology (E-UTRAN) of CSG sub-district or Hybrid sub-district in this approaching indication.
After step 302, source network side were received approaching indication that UE reports, owing to there is not the measurement on the configuration frequency f1 to dispose before, network side increased newly to the UE transmission and measures the signaling (by RRC Connection Reconfiguration) that disposes on the frequency f 1.
Step 303 after UE receives this signaling, is carried out the measurement on the frequency f 1, and the neighbor cell on the assessment frequency f 1 reports the cell information that satisfies report condition to the source network side.
Step 304, because the signal of Serving cell (sub-district 1) is lower than predetermined threshold, the source network lateral root selects jurisdiction district, base station 2 (target BS) 2 as the Target cell that switches according to measurement report, base station 1 sends handoff request (Handover Request) by the X2 interface between the base station to base station 2, comprise in this handoff request that UE reports near indication information, whether approaching should can be expressed as information near indication information, also can be the information that comprises frequency f 1 and/or access network technology E-UTRAN.

Step 306, base station 1 send switching command by RRC ConnectionReconfiguration to UE after receiving this affirmation signaling.Can also comprise the information that the objective network side allows to report approaching indication in this switching command, whether UE can report near indication after this can be used for.
Step 307, after UE receives switching command, obtain synchronously with Target cell after, send RRC to Target cell and connect to reshuffle and finish signaling (RRC Connection Reconfiguration Complete).
Need to prove that what UE reported can comprise one or more frequency informations in indicating, can be the frequency information of UTRAN system; Also can be one or more frequency informations in handoff request, also can be the frequency information of UTRAN system.
Step 308, after UE inserts Target cell and since Target cell known UE near indication information, when the objective network side receives that UE is behind the measurement report on the frequency f 1, the objective network side can specify UE to obtain certain CSG/Hybrid system information of subdistricts according to the cell information that reports; The CSG/Hybrid sub-district of UE Measurement Network side appointment, after obtaining the system message of CSG/Hybrid sub-district of appointment, implement initial access control, report initial access control information or handover preparation information to the objective network side, the objective network lateral root is implemented handover decisions according to initial access control information that reports or handover preparation information.
By above flow process, UE can switch to the CSG/Hybrid sub-district of mandate fast, avoids UE to insert the signaling process that sends once more behind the Target cell near indication information informing network side.
In the present embodiment, if base station 1 sends to base station 2 with the measurement report of UE on frequency f 1 in handoff procedure, base station 2 can specify UE to obtain certain CSG/Hybrid system information of subdistricts in the Handover Request Acknowledge signaling.
Need to prove, switching flow is realized by X2 interface in the present embodiment, as shown in Figure 1, if do not have X2 interface between base station 1 and the base station 2, base station 1 sends handoff request by core net to base station 2, comprises described near indication information in this handoff request.As shown in Figure 2, switching flow by core net is: base station 1 is switching demand (HandoverRequired) to the signaling that core net sends, core net is handoff request (Handover Request) to the signaling that base station 2 sends, and comprises described near indication information in switching demand and the handoff request; Base station 2 receives that the processing after the handoff request is same as described above, returns switching command (HandoverCommand) by core net to base station 1 then, and in target side, base station 2 is a Handover Request Acknowledge to the signaling that core net sends.
In the present embodiment,, there is not realization to be directly switch to the purpose of the CSG/Hybrid sub-district of mandate because source base station is that UE has implemented the switching to macrocell.Has the system message that time enough has obtained the CSG/Hybrid sub-district of mandate if be positioned at the UE of sub-district 1, and the signal quality of the CSG/Hybrid sub-district of this mandate satisfies the switching demand, source base station can directly be implemented to switch to the CSG/Hybrid sub-district of this mandate, and can not comprise near indication information in the handoff request this moment.
Embodiment two
In the LTE system, UE is positioned at macro base station (base station 1, source network side) jurisdiction district 1, is in connection status, the ability (reportProximityConfig is set to allowed) that the current area support is switched to closed user group cell.Network side is that UE has disposed the measurement configuration, and UE implements measurement according to measuring configuration, reports the cell information that satisfies report condition.
As shown in Figure 4, comprising:
Step 401, sometime, UE is according to the footprint or the fingerprint information of preserving, determine CSG or Hybrid sub-district near the mandate that inserts before certain, UE reports near indication to network side, comprises the frequency information (frequency f 1) and the access network technology (E-UTRAN) of CSG sub-district or Hybrid sub-district in this approaching indication.
Step 402, after receiving near indication, handover decisions is implemented according to existing measurement report in base station 1, the target switching cell of selecting is jurisdiction district 2, base station 2 (objective network side) (frequency f 2), base station 1 sends handoff request (HandoverRequest) by the X2 interface between the base station to base station 2, comprise in this handoff request that UE reports near indication information, this access indication information comprises the information of frequency f 1 and/or access network technology E-UTRAN.
Step 403, after handoff request is received in base station 2, implement access control, be this UE Resources allocation, simultaneously according to the access indication information in the handoff request, preserve this part information, because the objective network side is supported the switching (Inbound handover) to closed user group cell, and also be not the measurement configuration of UE configuration frequency f1, base station 2 is the configuration of the measurement on this UE configuration frequency f1 (can comprise the configuration of measurement clearance), base station 2 sends Handover Request Acknowledge (Handover RequestAcknowledge) by X2 interface to base station 1, and the measurement configuration and the objective network side that comprise in this Handover Request Acknowledge on the frequency f 1 allow to report approaching information of indicating.
After step 404, base station 1 are received this affirmation signaling, send switching command (the measurement configuration and the objective network side that comprise on the frequency f 1 allow to report approaching information of indicating) to UE by RRC ConnectionReconfiguration.
Step 405, after UE receives switching command, obtain synchronously with Target cell after, insert Target cell, send RRC to Target cell and connect to reshuffle and finish signaling (RRC Connection ReconfigurationComplete).
Step 406 after UE inserts Target cell, according to the configuration of the measurement on the f1 of configuration, is carried out and is measured, and reports the cell information that satisfies report condition.Sometime, report condition is satisfied in the sub-district 3 that UE records on the frequency f 1, the measurement report of UE reporting subdistrict 3; Base station 2 knows that according to the PCI of UE reporting subdistrict 3 this sub-district is the CSG sub-district of closed mode, and base station 2 notice UE read the system message of sub-district 3; After UE receives the measurement configuration of the system message that reads sub-district 3, in the measurement clearance of network side configuration or create the system message that reads sub-district 3 in the measurement clearance (autonomous GAP) automatically, after getting access to the system message of sub-district 3, UE implements initial access control, UE finds that the CSG ID of sub-district 3 is in the CSG tabulation of oneself preserving, be that UE is the member or the authorized user of sub-district 3, UE reports initial access control information or the handover preparation information (global cell identity that comprises sub-district 3 to base station 2, the tracking area coding, information about firms, and/or CSG ID), after the measurement report that comprises this initial access control information or handover preparation information that UE reports is received in base station 2, implement handover decisions, select sub-district 3 as the Target cells that switch, by switching flow, the CSG sub-district that UE can insertion authority.
Need to prove, in the present embodiment, base station 2 allows to report information near indication, base station 2 can wait for also that UE switches to send new measurement configuration on the frequency f 1 and the objective network side of comprising behind the sub-district 2 again and allow to report signaling near the information of indication by the measurement configuration and the objective network side of hand off signaling on UE configuration frequency f1.Present embodiment is applied to the LTE system, and for the UTRAN system, described method is suitable equally, and in the UTRAN system, the hand off signaling by core net is: source radio network controller RNC sends reorientation demand (Relocation Required) to core net; Core net sends re-positioning request (Relocation Request) to Target RNC; After Target RNC allows UE to switch, send re-positioning request affirmation (Relocation RequestAcknowledge) for its Resources allocation and to core net; Core net sends reorientation order (Relocation Command) to source RNC.Wherein in reorientation demand and re-positioning request, carry near indication information.The flow process that the UTRAN system implements to switch by the interface between the RNC (Iur) is: source RNC sends the re-positioning request (Enhanced Relocation Request) that strengthens to Target RNC; Target RNC is to send the relocation response (Enhanced Relocation Response) that strengthens to source RNC after the UE Resources allocation.Wherein the re-positioning request of Zeng Qianging is carried near indication information.In the UTRAN system, the source network side is source RNC; The objective network side is a Target RNC.
