Description
Technical field
The present invention relates to moving communicating field, in particular to a kind of report method and cell switching method of measurement report.
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 of radio reception device that is called Home eNodeB (Home NB or eNB) 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.
At present, Home eNodeB mainly contains three kinds of access modules: 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, as users such as kinsfolk or members of community, be called non-public authorized user group (Closed Subscriber Group through user's group of authorizing, CSG), authorization message is stored in subscriber equipment (User Equipment, UE) Subscriber Identity Module (Universal Subscriber Identity Module, USIM) in.The Home eNodeB of mixed mode allows all user to insert, but the user who belongs to CSG enjoys preferential or preferential condition.Sub-district under macro base station (NodeB or eNodeB) covers is called macrocell, and with respect to macrocell, the sub-district under Home eNodeB covers is called the CSG sub-district.UE can judge by the access module and the authorization message that is stored among the USIM of Home eNodeB under the CSG sub-district whether certain CSG sub-district allows its access.
The frequency resource that Home eNodeB can use operator to reserve as Home eNodeB specially, be called CSG dedicated frequency (dedicated carrier), also can use the frequency resource identical to be called mixed rate (mixed carrier) with macro base station, the minizone of same frequency is with physical layer identifications (Physical Layer Identity, PCI) distinguish, when family base station and macro base station use same frequency, operator can reserve PCI resource (PCI split) specially for Home eNodeB, and the PCI in the PCI split is only used in the CSG sub-district.There is a PCI CSG sub-district, and (Cell Global Identifier is CGI) with a non-public authorized user group id (CSG Identifier, CSG ID) for a global cell identity.Because physical layer identifications is limited, along with the magnanimity of Home eNodeB is disposed, PCI can not CSG sub-district of unique sign, a CSG ID also can identify a plurality of CSG sub-district, have only CGI unique in PLMN (public land mobile network) scope, therefore, UE and macro base station only get access to the unique definite CSG sub-district of CGI ability.
In mobile communication system,, give the good business experience of user in order to guarantee quality of service, when UE after certain sub-district and network connect, UE still needs the signal quality of its neighbor cell is measured, and selects proper cell to switch, so that satisfy the mobility requirement.With evolved Universal Terrestrial Radio Access Network network (Evolved Universal Terrestrial Radio Access Network, EUTRAN) be example, the detailed process that connected state is measured down is: network side will be measured control messages and send to UE, wherein, measure in the control messages and comprise measuring object (measurement object, MO), MO can be one group of sub-district on or a class frequency or the frequency; The measurement report configuration (reportconfiguration, RC), the attribute of RC allocating and measuring report, such as, measurement report is reporting events or periodic report and corresponding configuration; The measurement sign (measurement ID, MID), MID is the sign of each concrete measurement task, the related MO of MID and a RC, thereby measurement task of unique sign;
Measure thresholding (s-Measure) in addition in addition, represent the signal quality thresholding of persistent district; Measuring amount configuration (quantity configuration) is used to indicate concrete measuring amount; Measurement clearance configuration (measurement gap configuration) is used for the configuration of alien frequencies, isosystem measurement etc.UE can be known the number of tasks of measurement by the number of MID, the attribute that MO and the RC by the MID correspondence obtains the task of measuring, such as, should how to measure, should how to report etc.
The triggering of measurement report is divided into two kinds of Event triggered and periodic triggers, Event triggered is meant that the measuring amount of because measuring object (this moment, measuring object corresponded to the sub-district) satisfies to trigger to measure behind the event condition and reports, as, adjacent district wireless signals measuring amount triggers an incident during than the big 3db of persistent district, on give the correct time and can only report once, or report repeatedly with fixed interval.The periodic triggers measurement report does not need to satisfy the incident thresholding, can report as long as UE can obtain the measuring amount of measuring object, satisfies report cycle (reportInterval) at interval between reporting at every turn.If there are a plurality of measuring objects to report in the measurement report, on give the correct time, measuring object according to signal by strong to weak sequence arrangement, signal strength signal intensity comes top sub-district and is called best cell.At present, serve the measurement report of mobility purpose, UE only need report the PCI and the measuring amount of macrocell, and measuring amount that macro base station reports according to UE and known grand neighbor cell configuration information can be made switch decision.
Along with the magnanimity of Home eNodeB is disposed, certainly will require UE between macrocell and CSG sub-district, perhaps between CSG sub-district and CSG sub-district, switch, to satisfy the mobility demand.Simultaneously, because Home eNodeB has mobility as the subscriber equipment of plug and play, when family base station and macro base station use same frequency, interference problem between Home eNodeB and the macro base station, and the interference problem between the Home eNodeB also is one of the key factor that need consider of travelling performance, such as, to certain particular UE, on a hybrid frequency, there is a CSG sub-district and a macrocell that does not allow this UE to insert respectively, if UE is switched to this macrocell, UE will certainly be subjected to the strong jamming of this CSG sub-district, and then network just should not switch to this macrocell to UE when making switch decision.
Because Home eNodeB quantity is huge, adopt the working method of plug and play, has mobility, therefore, can not concern by configuring adjacent cell between macrocell and the CSG sub-district, promptly, macrocell does not have the information of CSG sub-district, whether macro base station is except can being whether the frequency resource of CSG special use or PCI belong to PCI split and judge whether certain sub-district is the CSG sub-district by frequency resource, can't obtain the out of Memory of Home eNodeB, and, Home eNodeB exists three kinds of access modules, macro base station can't know whether Home eNodeB allows a certain particular UE to insert, and existing measurement report mechanism obviously can't provide and switches to the CSG sub-district, and avoid Home eNodeB and macro base station, the information that the interference between Home eNodeB and the Home eNodeB is required.

UE can obtain the identification information of CSG sub-district from the system message of CSG Cell Broadcast CB, because wireless environment is abominable or UE does not have free time to go to obtain the system message of CSG sub-district, when perhaps UE goes to obtain the system message of CSG sub-district, the reasons such as time point of CSG cell broadcasting system message have just in time been missed, when reporting measurement reports, UE may also not get access to the identification information of CSG sub-district from the system message of CSG sub-district.
103:UE judges according to the identification information of authorization message of preserving among the USIM and the CSG sub-district that obtained whether the CSG sub-district allows its access, if allow its access, then execution in step 104; Otherwise, execution in step 105;
104:UE reports the CSG sub-district by measurement report to network side, comprises that in measurement report PCI, the measuring amount of CSG sub-district, the identification information and the informing network side CSG sub-district of CSG sub-district allow its access;
For EUTRAN CSG sub-district, its identification information comprises: one or more among CGI, TAC (Tracking AreaCode, tracking area coding), PLMN information, access module and the CSG ID; For UTRAN CSG sub-district, its identification information comprises: one or more among CGI, LAC (Location Area Code, lane place coding), RAC (Routing Area Code, Routing Area Code), PLMN information, access module and the CSG ID.
105:UE reports the CSG sub-district by measurement report to network side, can only comprise the PCI and the measuring amount of CSG sub-district in measurement report, does not report the identification information of CSG sub-district, and informing network side CSG sub-district does not allow its access;
Certainly, UE also can comprise the identification information of CSG sub-district in measurement report, serving other functions of network, such as being convenient to network side when carrying out Interference Control, finds the CSG sub-district according to the identification information of CSG sub-district, adjusts its cell parameter.
If the CSG cell operation is on dedicated frequency and the CSG sub-district has got access to the best cell in the CSG sub-district of identification information for UE on this dedicated frequency and do not allow UE to insert, UE reporting measurement reports not then.
106:UE judges whether to be necessary to obtain the identification information of CSG sub-district, obtains if desired, and then execution in step 107; Otherwise, execution in step 108;
For a specific UE, allow the quantity of CSG sub-district of its access normally limited, therefore, UE can preserve the information of its CSG sub-district of once inserting in this locality, is called footprint (footprint) information.When a CSG sub-district satisfies condition and need report, but until when all obtaining identification information less than the CSG sub-district during reporting measurement reports, UE can judge the follow-up identification information that whether is necessary to continue to obtain the CSG sub-district according to footprint information.
If the CSG cell operation is at dedicated frequency, satisfy on the measurement report trigger condition needs as a plurality of CSG sub-district and to give the correct time, if UE does not get access to the identification information of any one CSG sub-district, the temporary transient reporting measurement reports not of UE then, when UE gets access to the identification information of at least one CSG sub-district, reporting measurement reports.
107:UE reports the CSG sub-district, comprises the PCI and the measuring amount of CSG sub-district in measurement report, can also understand reporting measurement reports once more by informing network side UE behind the identification information that gets access to the CSG sub-district simultaneously;
Need obtain the CSG sub-district of identification information for not getting access to, expression UE once inserted this CSG sub-district, whether need further obtain its identification information still allows UE to insert to judge at present, because, interference might be caused to other sub-district of Serving cell and same frequency in this CSG sub-district, so, need report it.
108:UE reports this CSG sub-district, comprises the PCI and the measuring amount of CSG sub-district in measurement report.
Need not to obtain the CSG sub-district of identification information for not getting access to, expression does not need to consider whether it allows UE to insert, promptly, follow-uply can not obtain its identification information again, but it also may cause interference to other sub-district of Serving cell and same frequency, so, need report it.
Network side can be made switch decision according to the measurement report that UE reports.
By using example said method is described again below.
Wherein, in measurement report, adopt following method representation neighboring BS information for using example 1,2 and 3:
Do not obtain identification information, allow to insert: expression UE does not get access to identification information, and need obtain identification information, and the follow-up identification information that gets access to needs the CSG sub-district report by measurement report once more, or the expression macrocell, network can judge it specifically is CSG sub-district or macrocell according to PCI split information.
Do not obtain identification information, do not allow to insert: expression UE does not get access to identification information, and does not need to obtain the CSG sub-district of identification information.
Obtained identification information, allow to insert: expression has acquired identification information, and the CSG sub-district that allows UE to insert.
Obtained identification information, do not allow to insert: expression has acquired identification information, and the CSG sub-district that does not allow UE to insert.
In measurement report, can adopt the information that whether has got access to identification information and whether allowed to insert more than the bit sign respectively.
In measurement report, adopt following method representation neighboring BS information for using example 4,5 and 6:
Allow to insert, but do not report identification information in measurement report: expression UE does not get access to the CSG sub-district of identification information, or the expression macrocell, and network can judge it specifically is CSG sub-district or macrocell according to PCI split information.
Allow to insert, and report identification information in measurement report: expression has acquired identification information, and the CSG sub-district that allows UE to insert.
Do not allow to insert: expression has acquired identification information, and the CSG sub-district that does not allow UE to insert.
Can adopt a bit sign whether to allow the information that inserts in measurement report, network side can be known the type of CSG sub-district further combined with whether comprising identification information in the measurement report.
