Description
Technical field
The present invention relates to the communications field, handle method and apparatus in particular to a kind of measurement.
Background technology
In mobile communication system, in order to guarantee communication continuity, guarantee quality of service, give the good business experience of user, sub-district gravity treatment and switching all are the emphasis that designs in the mobile communication.In order to realize the sub-district gravity treatment smoothly, (User Equipment UE) need measure the signal quality of different districts subscriber equipment, so that select proper cell to carry out resident; When UE after certain sub-district and network connect (being after UE enters connected state), UE still needs to measure also to the signal quality of its neighbor cell, and the reporting measurement result gives network side, so that network side selects proper cell to switch, satisfy the mobility requirement, guarantee the continuity of customer service.
With 3G (Third Generation) Moblie Long Term Evolution (Long Term Evolution, LTE) system is an example, under connected state, the detailed process of measurement is as follows: network side will be measured control messages and send to UE, wherein, comprise in this measurement control messages: measuring object (MeasurementObject, MO), measurement report configuration (Report Configuration, attribute RC), measure sign (Measurement ID, MID), wherein, MO is the frequency of a LTE; The attribute of RC allocating and measuring report, for example, measurement report is reporting events or periodic report and configuration parameter corresponding, more for example, satisfy in the reporting events incident entry condition or incident leave the duration of condition (Time To Trigger, TTT); MID is the sign of each concrete measurement task, the related MO of MID and a RC, thereby measurement task of unique sign, that is, and the measurement configuration information on certain frequency of unique sign.In addition, also dispose in the measurement control messages: Serving cell quality threshold (s-Measure) is used to control UE and whether opens same frequency, alien frequencies, the isosystem measurement that is disposed; Measuring amount configuration (Quantity Configuration) is used to indicate concrete measuring amount; Measurement clearance configuration (Measurement Gap Configuration) is used to set up or discharge the configuration informations such as gap that are used for different-frequency measure.UE promptly knows the number of tasks of measurement by the MID number of configuration, and the attribute that MO and the RC by the MID correspondence obtains this measurement task is such as should how to measure should how to report etc.
The measurement report of reporting events is meant because the measuring amount of measuring object (this moment, measuring object corresponded to the sub-district) satisfies incident entry condition (Entry Condition), or the triggering measurement reports after leaving condition (Leaving Condition), promptly, UE defines one or more sub-districts and is continuing TTT satisfies certain measurement task (identifying with MID) in the time incident entry condition, these sub-districts are saved in this measurement task corresponding district tabulation (cellsTriggeredList, identify with MID) in, UE reporting measurement reports then.
In the LTE system, for all measurement tasks (identifying) that has been configured, open all the time except measurement task at Serving cell with MID, promptly UE measures Serving cell all the time; And serve set up Automatic Neighboring Relation (Automatic Neighbour Relation, ANR) the measurement task UE of purpose opens outside the measurement automatically, other all with frequently, alien frequencies, the isosystem measurement task all needs to meet the following conditions, UE just opens measurement, that is:
If this measurement needs gap configuration and gap to be configured, and if the signal measurement amount of Serving cell less than the s-Measure thresholding or the not configuration of s-Measure of configuration, UE measures the MO of this MID correspondence.After that is to say that UE receives the measurement configuration of network side, under the enough good situation of Serving cell signal (more than or equal to the s-Measure thresholding), UE does not open above-mentioned measurement, reduces unnecessary measurement with this, reduces the space interface signaling expense when reducing UE power consumption.Be that s-Measure is a common switch of opening with frequency, alien frequencies, isosystem measurement.
In the LTE system, measuring amount under the connected state can be Reference Signal Received Power (the Reference Signal Received Power of sub-district, RSRP), what RSRP measured is on the measurement bandwidth of this place, sub-district frequency, carry " reference signal (the Cell-specific Reference Signals; CRS) the linear power mean value of " physical resource unit (Resource Element), unit is dBm that the sub-district is specific of this sub-district.Measuring amount under the connected state can also be Reference Signal Received Quality (the Reference SignalReceived Quality of sub-district, RSRQ), RSRQ need measure the RSRP and received signal intensity indication (the Received Signal Strength Indicator of sub-district, RSSI), wherein, rssi measurement be on the measurement bandwidth of this place, sub-district frequency, the total received power of all Physical Resource Block (Resource Block), the power that comprises people having a common goal's (Co-Channel) Serving cell and adjacent sub-district, neighboring trace (Adjacent Channe) disturbs, thermal noise etc.RSRQ is defined as that (N * RSRP/RSSI), unit is dB, and wherein, N is illustrated in the Physical Resource Block number on the measurement bandwidth of this place, sub-district frequency.Physical resource unit, physical resource is fast, notions such as measurement bandwidth are the notion of LTE system physical layer, specifically can be with reference to third generation partner program (3rd Generation Partnership Project, 3GPP) related protocol 36.211 of physical layer and 36.133 description.
From above definition as can be seen, what RSRP reflected only is the available signal power of sub-district, and RSRQ has then reflected the ratio of useful signal and interference on the basis of RSRP.At present, in the LTE system, whether open under the connected state, measure the RSRP of Serving cell exactly, when the RSRP of Serving cell＜s-Measure, open above-mentioned measurement with frequency, alien frequencies, isosystem measurement.In addition, Serving cell is also existed the measurement of RSRQ, such as A1 incident (signal strength signal intensity of Serving cell surpasses thresholding) and A2 incident (signal strength signal intensity of Serving cell is lower than thresholding), to A1, A2 incident, general measure be the RSRQ value of Serving cell, the Serving cell A1 that network side can report according to UE, the measurement result of A2 incident, configuration (according to the A2 incident) or deletion (according to the A1 incident) measuring object are the alien frequencies frequency, and/or measuring object is the measurement task of different system frequency.
In order can various high-speed radio access services to be provided and preferential on the rate to be provided to the user, remedy existing distributed cellular radio communication system simultaneously in this and cover defect of insufficient, introduced Home eNodeB (Home (e) NodeB abbreviates H (e) NB as) in the wireless communication technology.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.The frequency resource that Home eNodeB can use operator to reserve as Home eNodeB specially is called special-purpose frequency, also can use the frequency resource identical with macro base station, is called the mixing frequency.Home eNodeB has three kinds of access modules at present: open mode, closed mode and mixed mode, and wherein, 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 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, is stored in the subscriber equipment, and the Home eNodeB of closed mode covers abbreviation CSG sub-district, sub-district down; The Home eNodeB of mixed mode also allows non-Member Users to insert except the permission Member Users inserts.
Because Home eNodeB is a kind of subscriber equipment of plug and play, its deployment, open and close etc. are user's independent behaviour, except that special requirement, managed by operator's full powers, therefore after introducing Home eNodeB, existing wireless network will become a heterogeneous network (Heterogeneous Deployments), provide the schematic diagram of disposing wireless network arrangement in the LTE system of Home eNodeB front and back as Fig. 1, suppose that here the working frequency points of all macrocells is f1.
UE resides in sub-district 1, when not disposing Home eNodeB (a), when UE is in the macrocell central area (from the base station when nearer, such as Serving cell RSRP 〉=s-Measure), this UE can not be subjected to the interference from the adjacent area, even interference is arranged, the interference of adjacent area is also very little with respect to the signal quality of Serving cell, therefore UE can carry out excellent communications at Serving cell, guarantees good business experience, and promptly UE does not need to open with frequency, alien frequencies, isosystem measurement.But, after disposing Home eNodeB, Home eNodeB can use the frequency identical with Serving cell, and can be deployed in any position in the macrocell coverage area in principle, and macrocell may not known this, wireless network will become a heterogeneous network this moment, if the RSRP＜s-Measure of and if only if Serving cell just opens with frequently, alien frequencies, isosystem measurement, on the one hand, even UE is in macrocell central area (RSRP 〉=s-Measure), if but meanwhile UE again near one during with frequently home base station cells (such as the CSG sub-district that does not allow this UE to insert), UE also will be subjected to the strong jamming from home base station cells, have a strong impact on the user's communications quality even cause call drop; On the other hand, because the RSRP 〉=s-Measure of Serving cell, UE opens never to the measurement with frequency, alien frequencies, different system, will cause UE can't switch forever/gravity treatment is to family's base station cell, it is preferential with corresponding rate to cause UE can't enjoy faster and better business, influence user service experience, also can't share load simultaneously, lost the meaning of disposing Home eNodeB for macrocell.
Can't initiate the problem of cell measurement effectively at measuring processing method in the correlation technique, not propose effective solution at present as yet.

Embodiment one
Fig. 3 is the schematic diagram according to the wireless network arrangement of a kind of macrocell of the embodiment of the invention and home base station cells.As shown in Figure 3, UE resides in macrocell 1 (be operated in and mix on the frequency f1), macrocell 2 and macrocell 3 are respectively the grand adjacent area of same frequency (be operated in and mix on the frequency f1) and the grand adjacent area of alien frequencies (being operated on the frequency f2) of macrocell 1, be deployed with a plurality of CSG sub-district in macrocell 1 coverage, wherein, CSG1 and macrocell 1 are with frequently, and CSG1 is positioned at the central area of macrocell 1, the base station under the promptly close macrocell 1; CSG1 does not allow this UE to insert, and promptly the closed user group id unauthorized of CSG1 is given this UE.
Fig. 5 is the flow chart according to the measurement processing method of the embodiment of the invention one.As shown in Figure 5, the measurement processing method according to the embodiment of the invention mainly comprises the steps:
S501:UE sets up RRC at macrocell 1 and connects, after this, if the CSG ability that this UE is not preserved in the base station under the macrocell 1, then the base station under the macrocell 1 obtains the CSG ability of this UE, it comprises: whether UE supports CSG, and whether UE preserves the closed user group id (CSG-ID) of permission access etc.
The base station obtains the CSG ability of UE, be specially, UE sets up Mobility Management Entity (the Mobility Management Entity of process from core net by the initial UE context, MME) locate to obtain the CSG ability (if MME preserve this UE CSG ability) of this UE, this ability can be carried at the initial UE context that MME sends to the base station and set up in the request (INITIAL CONTEXT SETUP REQUEST).If UE never registered at this MME, promptly this MME does not preserve the CSG ability of this UE, then the base station can also be inquired about to obtain the CSG ability of this UE to UE by UE capability query process, and the CSG ability of UE can be carried in the UE ability information (UECapabilityInformation) of UE response base station in the UE capability query process.
In the present embodiment, this UE supports CSG, and this UE preserves and allow the closed user group id that inserts, and promptly this UE is authorized to allow to insert the closed user group of being preserved.
S502: the base station sends measures configuration messages (being included in the RRC connection reshuffles in the RRCConnectionReconfiguration message) to UE, this measurement is configured to UE and has disposed two Serving cell quality threshold, S-measure-RSRP and S-measure-RSRQ, these two Serving cell quality threshold are whether UE starts the common switch with frequency, alien frequencies, isosystem measurement, wherein, S-measure-RSRP represents that the RSRP of Serving cell measures thresholding, and S-measure-RSRQ represents that the RSRQ of Serving cell measures thresholding.Under connection status, UE measures Serving cell all the time, as the RSRP of Serving cell measured value S
RSRP＜S-measure-RSRP, and/or the RSRQ measured value S of Serving cell
RSRQDuring＜S-measure-RSRQ, UE unlatching all-network side has been configured same frequency, alien frequencies, the isosystem measurement to UE.Work as S
RSRP〉=S-measure-RSRP and S
RSRQDuring 〉=S-measure-RSRQ, UE stops the all-network side has been configured same frequency, alien frequencies, isosystem measurement to UE.
In addition, measure in the configuration messages also for UE has disposed common frequency measurement task a: MID1 MO (f1), RC (A3 incident, the signal of adjacent sub-district is than the high side-play amount of being scheduled to of Serving cell).Other measurement parameters do not repeat them here according to prior art arrangement, and other embodiment herewith illustrate.
S503: shown in the mobile alignment of UE among Fig. 3, UE moves closer to CSG1, during to position A, although the RSRP measurement result of macrocell 1 still is higher than S-measure-RSRP, but because near CSG1, UE measures the interference signal from CSG1, so the RSRQ measurement result of macrocell 1 satisfies S
RSRQ＜S-measure-RSRQ, UE begin to carry out the measurement to MID1.
S504:UE measures the assessment back and judges that the signal of CSG1 satisfies the A3 incident that measurement task MID1 is disposed, UE is saved in CSG1 in the cell list that MID1 identifies, and, carry the information of CSG1 in the measurement report, and do not allow the indication that inserts to the base station reporting measurement reports.
S505: after the measurement report of UE is received in the base station, judge that CSG1 does not allow UE to insert, as shown in Figure 3, in the residing position of UE, resident because of there not being other proper cell to be fit to UE in the current wireless network, so the base station do not issue any switching indication, UE continues to reside in macrocell 1.At this moment, in order to reduce the interference of CSG1 to UE, the base station can adopt presence of intercell interference control method quite ripe in the prior art to reduce the interference of CSG1 to UE, thereby guarantees that this UE obtains the excellent communications quality in macrocell 1.
As from the foregoing, adopted measurement processing method used in the present invention, RSRP measured value＜the s-Measure of the Serving cell that can solve that and if only if in the prior art just opens with frequency, alien frequencies, isosystem measurement, thereby customer service when the RSRP of Serving cell measured value＞S-Measure, because of UE can't open with frequency, alien frequencies, isosystem measurement, the base station can't be known the interfere information of home base station cells and cause UE to be subjected to interference from Home eNodeB, have a strong impact on the drawback of user experience.
S506: shown in the mobile alignment of UE among Fig. 3, UE leaves CSG1 gradually, and during to position B, UE measures the S of macrocell
RSRP＞S-measure-RSRP and S
RSRQ＞S-measure-RSRQ, UE stop the measurement to MID 1, and delete above-mentioned cell list, promptly stop measurement and the measurement of MID1 are reported.
Adopt measurement processing method used in the present invention, UE effectively On/Off to adjacent sub-district, especially to the measurement of home base station cells.As the step S503-S505 of present embodiment, UE opens the measurement to MID1, and reports CSG1 to the base station, and the base station can also be implemented presence of intercell interference control in view of the above, thereby reduces the interference of CSG1 to UE, guarantees UE excellent communications quality.If CSG1 allows UE to insert, the base station can switch to this UE among the CSG1, provides better service and more preferential rate for UE on the one hand, guarantees the experience of user's favorable service; After on the other hand UE being switched to CSG1, also can effectively alleviate the resource load of macrocell 1.Effectively guaranteeing the experience of user's favorable service simultaneously, as present embodiment S506, UE stops the measurement of MID1 and reports, and the inventive method has also been avoided the unnecessary measurement to Home eNodeB effectively, thereby reduces the power consumption of UE, reduces the space interface signaling expense.
Embodiment two
Fig. 4 is the schematic diagram according to the wireless network arrangement of the another kind of macrocell of the embodiment of the invention and home base station cells.As shown in Figure 4, UE resides in macrocell 1 and (is operated on the frequency f1 of macrocell special use, promptly can not dispose home base station cells on this frequency), macrocell 2 and macrocell 3 are respectively the grand adjacent area of same frequency (being operated on the frequency f1) and the grand adjacent area of alien frequencies (being operated on the frequency mixing f2) of macrocell 1, be deployed with alien frequencies CSG sub-district in the macrocell coverage area, wherein as shown in Figure 4, CSG1 is operated in and mixes on the frequency f2, the CSG1 position is near the edge zone of macrocell 1, CSG1 allows this UE to insert, and promptly the closed user group id of CSG1 has licensed to this UE.
Fig. 6 is the flow chart according to the measurement processing method of the embodiment of the invention two.As shown in Figure 6, the measurement processing method according to the embodiment of the invention mainly comprises the steps:
S601: with step S501.
S602: the base station sends measures configuration messages (being included in the RRC connection reshuffles in the RRCConnectionReconfiguration message) to UE.Because macrocell 1 is operated on the frequency f1 of macrocell special use, and can not dispose home base station cells at f1, so this measurement configuration messages has only disposed a Serving cell quality threshold of measuring based on RSRP for UE, be S-measure and disposed a value of measuring based on RSRP, unit is dBm.Like this, after UE receives above-mentioned measurement configuration messages, as the RSRP of Serving cell measurement result S
RSRPDuring＜S-measure, UE unlatching all-network side has been configured same frequency, alien frequencies, the isosystem measurement task to UE.
Above-mentioned measurement configuration messages can carry above-mentioned one or more measurement tasks, for example, these measurement tasks can for:
MID1, MO (f1), RC (A1 incident, the RSRQ measurement result of Serving cell is higher than predetermined threshold).
MID2, MO (f1), RC (A2 incident, the RSRQ measurement result of Serving cell is lower than predetermined threshold).
MID3, MO (f1), RC (A3 incident, the signal of adjacent sub-district is than the high predetermined side-play amount of Serving cell).
S603: shown in the mobile alignment of UE among Fig. 4, UE is before the B of in-position, and the RSRP measurement result of macrocell 1 all satisfies S
RSRP＞S-measure-RSRP so UE only measures macrocell 1, promptly only opens MID1, and the measurement to MID3 is not opened in the measurement of MID2.
UE is when the A of in-position, and the RSRP measurement result of Serving cell still satisfies S
RSRP＞S-measure-RSRP, the RSRQ measurement result that UE measures assessment judgement macrocell 1 satisfies the A2 incident that measurement task MID2 is disposed, UE is to the base station reporting measurement reports, carry the information of macrocell 1 in the measurement report, comprise macrocell 1 Physical Cell Identifier (Physical Cell Identity, PCI) and the RSRQ measurement result.
S604: after the measurement report that UE reports is received in the base station, RSRQ measurement result according to the macrocell that is reported, on the existing measurement configure base of step S602, (promptly do not delete the measurement task MID1 that originally has been configured, MID2 and MID3, here, can regard the task of measurement MID1-MID3 as second measurement task), revise the measurement configuration of UE, and new configuration information sent to UE, for example new configuration information can comprise: new measurement task (here, new measurement task can be one or more, and can regard new measurement task as first measurement task) and measuring based on RSRP respectively and the Serving cell quality threshold of RSRQ measurement for UE configuration, be value that S-measure configuration measures based on RSRP respectively (for convenience of description, present embodiment characterizes with the RSRP-Range value, unit is dBm) and the value measured based on RSRQ (for convenience of description, present embodiment is with RSRQ-Range value sign, and unit is dB).After UE receives new configuration information, as the RSRP of Serving cell measurement result S
RSRPThe RSRP-Range value of＜S-measure, perhaps the RSRQ measurement result S of Serving cell
RSRQDuring the RSRQ-Range value of＜S-measure, UE carries out the measurement task of all Serving cells (base station) configuration, comprises the first measurement task and the second measurement task, promptly opens the all-network side and has been configured same frequency, alien frequencies, isosystem measurement to UE.Work as S
RSRPRSRP-Range value and the S of 〉=S-measure
RSRQDuring the RSRQ-Range value of 〉=S-measure, UE stops the all-network side has been configured same frequency, alien frequencies, isosystem measurement to UE.The RSRQ-Range value is configured to be less than or equal to the RSRQ value of the macrocell 1 that UE reports among the S603 in the present embodiment.
Above-mentioned new measurement task (i.e. the first measurement task) can be the one or more different-frequency measure tasks for UE configuration, for example, this different-frequency measure task can for:
MID4, MO (f2), RC (A4 incident, the signal of adjacent sub-district surpasses predetermined threshold).
S605:UE shown in the mobile alignment of UE among Fig. 4, arrives between the B of position the RSRP measurement result S of macrocell at position A after receiving new configuration information
RSRPThe RSRP-Range value of＞S-measure, the RSRQ measurement result S of macrocell
RSRQThe RSRQ-Range value of＜S-measure, at this moment, UE begins to carry out the measurement to MID3 and MID4.
Shown in the mobile alignment of UE among Fig. 4, UE only is through CSG1, thus in this measuring process, there is not the sub-district to satisfy trigger conditions, so UE does not report any measurement report to give the base station.
Adopt measurement processing method used in the present invention, UE can effectively open adjacent sub-district, especially the measurement of home base station cells, if CSG1 satisfies trigger conditions in the present embodiment, UE reports the information of this CSG1 to give the base station, and CSG1 allows UE to insert, and the base station can switch to this UE among the CSG1, provide better service and more preferential rate for UE on the one hand, guarantee the experience of user's favorable service; After on the other hand UE being switched to CSG1, also can effectively alleviate the resource load of macrocell 1.
S606: shown in the mobile alignment of UE among Fig. 4, UE is through after the B of position, the RSRP measurement result S of macrocell
RSRPThe RSRP-Range value of＜S-measure, the RSRQ measurement result S of macrocell
RSRQThe RSRQ-Range value of＜S-measure, at this moment, UE continues to carry out the measurement to MID3 and MID4.
S607:UE measures assessment and judges that macrocell 2 satisfies the A4 incident that MID4 disposes, UE is saved in macrocell 2 in the cell list that MID4 identifies, and, carry the information of macrocell 2 in the measurement report to the base station reporting measurement reports, comprise PCI and RSRP measurement result etc.
S608: the measurement report of UE is received in the base station, and in conjunction with the RRM algorithm of base station, judgement need be switched to macrocell 2, and the base station switches to macrocell 2 to UE.
Need to prove that the Serving cell quality threshold configuration among embodiment one and the embodiment two only is a kind of preferred embodiment, the present invention is not limited to this.
Embodiment three
