Description
Technical field
The present invention relates to wireless communication technology, relate in particular to the adjacent area type setting system and the method for a kind of LTE system.
Background technology
In traditional third generation mobile (3G) system, be Neighboring Cell List (NRT) and the adjacent area attribute of each cell configuration with frequency/different frequency/different system by the Operation and Maintenance personnel.The sub-district is these adjacent area tables of broadcasting in system message both, also can send subscriber equipment (UE) in dedicated signaling.UE is according to the Neighboring Cell List of network appointment, the adjacent sub-district in the monitoring form.In Long Term Evolution (LTE) system, great change has taken place in the mode of UE monitoring adjacent area.In the LTE system, the neighboring BS information of sub-district no longer relies on the Operation and Maintenance personnel to be configured.Generally, Neighboring Cell List need not broadcasted in system message, does not need to transmit in measuring configuration signal yet.That is, the Target cell that need indicate UE to measure by network not, but independently measure by UE, this process is called as automatic adjacent section (ANR).For the information of adjacent area, PCI for example, ECGI, TAC and PLMN etc., UE can obtain by measurement, and reports base station (eNB), thereby sets up the neighboring BS relationship of a correspondence in the NRT of eNB table.
Adopt above-mentioned measurement mechanism, neighbor cell is to find automatically by the measurement of UE, no longer is fully by the (O﹠amp of management station; M) configuration.But for some adjacent area attribute, base station (eNB) or UE can't judge, be by O﹠amp at present; M is provided with, such as No X2, No Remove, No Ho etc., and whether the decision of these attributes allows X2 to set up, and whether allows to delete the adjacent area and whether allows function such as switching.So the flow process of ANR is that eNB is to O﹠amp after measuring the discovery adjacent area by UE at present; M reports, and waits for O﹠amp; M is provided with No X2, No Remove, and attributes such as No Ho, and these attributes are added in the Neighboring Cell List.
But for the adjacent area type, UE can't independently measure and report eNB, and does not also have the attribute about the adjacent area type in the existing Neighboring Cell List, so eNB can't know the adjacent area type at UE place.The type of adjacent area mainly contains the neighboring BS relationship (Overlapping Coverage) of overlapping covering, and promptly the coverage of the sector of adjacent area correspondence overlaps fully; The neighboring BS relationship (HierarchicalCoverage) that layering covers, promptly the sector coverage of adjacent area correspondence is not of uniform size causes; And the neighboring BS relationship of adjacent covering (Neighboring Coverage), the zone that promptly overlaps between the sector of adjacent area correspondence and cover.
In addition, for different adjacent areas type, the various processing modules of eNB, for example load balancing (loadbalance) and/or Inter-Cell Interference Coordination module have different disposal strategy and algorithm.Owing to can't obtain the type of adjacent area, thereby eNB can't utilize the adjacent area type to do flexible processing and switching, can only be according to waiting until between the common adjacent area that UE measures the signal of adjacent area, UE could be moved to corresponding district, increase the processing complexity of system so undoubtedly, prolong the processing time, can not carry out the operation of corresponding load balancing or interference coordination timely and effectively.

Fig. 1 is the structural representation of the LTE system adjacent area type setting system of the embodiment of the invention, and as shown in the figure, adjacent area of the present invention type setting system comprises subscriber equipment (UE) 10, base station (eNB) 20 and the (O﹠amp of management station; M) 30.UE 10 measures and finds new adjacent area and report to eNB 20, and the adjacent area that eNB20 reports according to UE 10 is further to O﹠amp; M 30 reports, and receives O﹠amp; The neighboring cell type attribute of M 30 feedbacks is also added in the neighborhood region correlation chart.O﹠amp; 30 of M are provided with neighboring cell type attribute according to reporting of eNB 20, and the neighboring cell type attribute of correspondence is fed back to eNB 20.
Below, in detail adjacent area of the present invention type setting system operation principle is elaborated in conjunction with Fig. 1 embodiment.
ENB 20 at first sends to UE 10 and measures configuration, and for example frequency, wireless access technology parameters such as (RAT) are carried out the active measurement to trigger UE 10.UE 10 is according to the configuration of the measurement triggering of eNB 20, measures the information of reference signal power (RSRP) adjacent area of etc.ing of finding physical-layer cell identifier (PCI) for example, receiving, and the information of measurement is reported to eNB 20.The PCI information that eNB 20 reports according to UE 10 judges that corresponding adjacent area is known adjacent area or newfound adjacent area, if judging corresponding adjacent area is unknown adjacent area, then send to measure and be provided with to UE 10, parameters such as report CGI=TRUE for example are set, report eNB 20 to require sub-district overall identification (CGI) information that UE 10 should the unknown adjacent area.Thereby eNB 20 is according to the reporting information of UE 10, and the PCI and the CGI information of corresponding adjacent area is reported O﹠amp; M 30.
O﹠amp; 30 reporting informations according to eNB 20 of M are provided with neighboring cell type attribute (Neighbor type) and carry out assignment, and the neighboring cell type attribute of this adjacent area is fed back to eNB 20.O﹠amp; The Neighbor Type value that M 30 is provided with comprises:
The neighboring BS relationship of overlapping covering--Overlapping Coverage;
Neighboring BS relationship--the Hierarchical Coverage that layering covers;
The neighboring BS relationship of adjacent covering--Neighboring Coverage.
Concrete implication and value strategy can be referring to Fig. 2 a-2c, and these figure have shown O﹠amp respectively; The neighboring BS relationship of the neighboring cell type attribute correspondence that M 30 is provided with.Fig. 2 a neighboring BS relationship figure of superimposition lid that attaches most importance to wherein, Fig. 2 b is the neighboring BS relationship figure that layering covers, Fig. 2 c is the neighboring BS relationship figure of adjacent covering.
Suppose among the figure that Cell A and Cell B among the embodiment are used for representing this Serving cell and its adjacent area at UE 10 places respectively, shown in Fig. 2 a, Cell A and Cell B overlap fully; Shown in Fig. 2 b, not of uniform size the causing of coverage (or area coverage) of CellA and Cell B, the coverage of Cell B is less, and the Cell A that the scope that can be capped is bigger covers fully; Shown in Fig. 2 c, the zone that between Cell A and Cell B, overlaps and cover.
The neighboring BS relationship that the layering that shows for Fig. 2 b covers, O﹠amp; The value of 30 couples of Neighbour Type of M parameter comprises two parts (Hierarchical Coverage, HCS Coefficient), and wherein HCS coefficient gets True: represent that this Serving cell area coverage is little, the adjacent area area coverage is big; False: represent that this Serving cell area coverage is big, the adjacent area area coverage is little.
ENB 20 is abnormal conditions such as congested or sub-district part faulty resource according to the load of sub-district, UE 10 place, and in conjunction with O﹠amp; The neighboring cell type attribute of M 30 feedbacks, take adjacent area switchover policy flexibly and UE 10 is switched in the corresponding adjacent area, thereby carry out that cell load is balanced to be adjusted and/or uses that degrade of sub-district that sub-district part faulty resource causes, do not interrupt with customer service under the assurance abnormal conditions.
Below, in conjunction with the different adjacent areas type of above-mentioned Fig. 2 a, Fig. 2 b and Fig. 2 c, eNB 20 is carried out the adjacent area switching of UE 10 and make an explanation.
For the neighboring BS relationship of the overlapping covering shown in Fig. 2 a, no matter where UE 10 is being in the sub-district, for example be positioned at any position, overlapping region shown in the figure, eNB 20 can do switching between CellA and Cell B.Be that UE 10 can not need to measure, and between Cell A and Cell B, do blind switching.
Neighboring BS relationship for the overlapping covering shown in Fig. 2 b, if UE 10 is arranged in Cell B, be the area coverage of the area coverage of 10 Serving cells of UE (corresponding Cell B) less than adjacent area (corresponding Cell A), then any therein position eNB 20 can carry out the blind switching of UE 10 in Cell A.But when UE 10 is in Cell A, be the area coverage of the area coverage of 10 Serving cells of UE (corresponding Cell A) greater than adjacent area (corresponding Cell B), then UE 10 can only be when being arranged in the overlay area of Cell A and Cell B area coverage correspondence (overlapping region of Cell A and Cell B overlay area correspondence shown in Fig. 2 b), could be to doing load balancing by Cell B, be that UE must judge it whether in the coverage of Cell B by measurement, eNB 20 could determine whether do switching to cellB.Therefore, 20 pairs of layerings of eNB cover the adjacent area type of neighboring BS relationship, need be in conjunction with O﹠amp; (Hierarchical Coverage, HCS Coefficient) parameter value of M30 is judged the size of this Serving cell area coverage and adjacent area area coverage, thus the switching that the blind switching of corresponding execution still need be measured.
Neighboring BS relationship for the adjacent covering shown in Fig. 2 c, only in the common overlay area of Cell A and Cell B, (see the overlapping region among the figure) and just can do handover operation, promptly must be measured the signal of adjacent area by UE 10, eNB 20 just can switch to UE 10 corresponding adjacent area.
In addition, O﹠amp; M 30 is provided with neighboring cell type attribute newfound the time, and in the dynamic running process of system, causes the adjacent area type to change O﹠amp if the coverage property of sub-district changes; M 30 can upgrade according to the change dynamics of adjacent area type and revise neighboring cell type attribute, real-time informing eNB 20 real neighboring BS relationship.
By in neighborhood region correlation chart, increasing the attribute of adjacent area type (Neighbor Type), reflect neighboring BS relationship truly.Make the minizone comprise that processing modules such as for example load balancing module and/or Inter-Cell Interference Coordination module can take different available strategies according to different neighboring BS relationship characteristics, improved the performance and the flexibility of system greatly.
The characteristic of this neighboring BS relationship can also be used for eNB 20 and judge when can carry out blind switching, thereby under the situation that does not need to measure, switch the adjacent area that can carry out respective user equipment simply, neatly, in time solves the problem that customer service is interrupted under the abnormal conditions such as the congested and/or sub-district fault of cell load.Like this, blind flexibly switching has reduced the complexity of system's alignment processing, carries out respective operations timely and effectively thereby shorten the processing time.While O﹠amp; Operation is simple for M 30, and the condition that is provided with of attribute is also very clear.
Fig. 3 is a kind of architecture of base station schematic diagram that the embodiment of the invention proposes, and this base station (eNB) 20 comprises and report unit 22 and neighborhood region correlation chart administrative unit 24.Report unit 22 that subscriber equipment in this Serving cell is measured the new adjacent area of finding and report to management station, 24 neighboring cell type attribute that management station is provided with of neighborhood region correlation chart administrative unit are added in the neighborhood region correlation chart.ENB20 can also comprise the switch unit (not shown), switch unit is in conjunction with the neighboring cell type attribute in the neighborhood region correlation chart, and the load of sub-district is congested and/or situation such as sub-district failure exception, carries out subscriber equipment to blind switching of the load balancing of corresponding adjacent area and/or the blind switching of emergency treatment.
Fig. 4 is a kind of management station structure of the embodiment of the invention, (O﹠amp of management station as shown in the figure; M) 30 comprise that the adjacent area type is provided with unit 32 and feedback unit 34, and the adjacent area type is provided with the reporting of according to the base station subscriber equipment measure being found unit 32 of new adjacent area neighboring cell type attribute is set, and feedback unit 34 feeds back to reporting base station with neighboring cell type attribute.Wherein, the adjacent area type is provided with the unit and also revises neighboring cell type attribute according to the change dynamics of adjacent area type, and gives corresponding base station by feedback unit 34 with adjacent area type real-time informing.
Fig. 5 provides the flow chart of steps of the adjacent area type method to set up of LTE of the present invention system, and at first subscriber equipment will be measured the new adjacent area of finding and report to the base station, and report (step 102) by described base station to management station.Wherein, subscriber equipment for example reports corresponding PCI and the CGI information of measuring the adjacent area to the base station, and gives management station by the base station with corresponding adjacent zone information reporting.
Then, management station is provided with neighboring cell type attribute and feeds back to base station (step 104) according to reporting of base station.Neighboring cell type attribute (Neighbor type) value that management station is provided with comprises: the neighboring BS relationship of overlapping covering--Overlapping Coverage; Neighboring BS relationship--the Hierarchical Coverage that layering covers; The neighboring BS relationship of adjacent covering--Neighboring Coverage.Wherein when the neighboring cell type attribute that is provided with was the neighboring BS relationship of layering covering, management station comprised the parameter that is used for representing described Serving cell area coverage and described adjacent area area coverage size respectively to the value of neighboring cell type attribute.In addition, the neighboring cell type attribute that is provided with is also revised according to the change dynamics of adjacent area type by management station, and to base station feedback.
The base station obtains neighboring cell type attribute and adds (step 106) in the neighborhood region correlation chart to.By adjacent area of the present invention type method to set up, the base station can increase the attribute of adjacent area type in neighborhood region correlation chart, to reflect neighboring BS relationship truly.Thereby make for example load balancing module of minizone, Inter-Cell Interference Coordination module etc. to take different available strategies, improved the performance and the flexibility of system greatly according to different neighboring BS relationship characteristics.
Fig. 6 is the adjacent area changing method flow chart of steps of LTE system customer equipment of the present invention, and as shown in the figure, wherein step 202,204 identical with the operation principle of the step 102 of Fig. 5 and 104 repeats no more here.In step 206, the base station obtains described neighboring cell type attribute adds in the neighborhood region correlation chart, and according to neighboring cell type attribute subscriber equipment is carried out switching.
When neighboring cell type attribute was represented the neighboring BS relationship of overlapping covering, the blind switching of subscriber equipment between this Serving cell and adjacent area can be carried out in the base station.Promptly, do not need the measurement of subscriber equipment can between the sub-district, do switching no matter where subscriber equipment is in the sub-district.
When neighboring cell type attribute is the neighboring BS relationship of layering covering, two kinds of situations of adjacent area switching difference of subscriber equipment are carried out in the base station: the one,, for area coverage this Serving cell less than the adjacent area, the blind switching of subscriber equipment between the bigger adjacent area of this Serving cell and area coverage carried out in the base station.That is, if subscriber equipment is arranged in this less Serving cell of area coverage, then the switching that does not need subscriber equipment to measure can be carried out in any position in the sub-district; The 2nd,, for area coverage this Serving cell greater than the adjacent area, need subscriber equipment at first to measure to judge it whether to be arranged in the overlay area of the less adjacent area correspondence of this Serving cell and area coverage, and the subscriber equipment that is positioned at the overlay area is just carried out switching.
When neighboring cell type attribute was the neighboring BS relationship of adjacent covering, the switching of described subscriber equipment was carried out in the base station according to the signal of the described adjacent area of described subscriber equipment measurement.That is, must be measured the signal of adjacent area by subscriber equipment, in the common overlay area of this Serving cell and adjacent area, the base station just can switch to subscriber equipment corresponding adjacent area.
Adjacent area of the present invention changing method is judged the situation that can carry out blind switching in conjunction with adjacent area type characteristic, thereby under the situation that does not need to measure, switch the adjacent area that can carry out respective user equipment simply, neatly, the problem that customer service is interrupted under the abnormal conditions such as congested and/or sub-district part faulty resource with timely solution cell load.Like this, blind flexibly switching has reduced the complexity of system's alignment processing, carries out respective operations timely and effectively thereby shorten the processing time.
