Description

A kind of measurement control method of different system adjacent cell relation and base station

Technical field

The present invention relates to wireless communication technology field, more particularly to a kind of measurement control method of different system adjacent cell relation and Base station.

Background technology

At present, public land mobile net network safeguards that the work for most costing manpower is to handle neighboring BS relationship for cell switching, This is carried out during being operated in wireless network O＆M, and with wireless network deployment and long-term existence.But with switching The standard increase of support, for example 2G/3G/4G is supported, the workload of artificial treatment can be in exponential increase, and therefore, automatic adjacent section is closed System (Automatic Neighbor Relation, abbreviation ANR) is optimized to for self-organizing self-optimizing network (Self- Organizing and Self-Optimization Network, abbreviation SON) most important characteristic, and earliest by specification Change SON functions.

When disposing new base station or cell, ANR functions can reduce the work of processing cell neighboring relations, correct to realize ANR functions, the probability of success of cell switching can be increased, reduced because of call drop and hydraulic performance decline caused by neighboring BS relationship mistake. Long Term Evolution (Long Term Evolution, abbreviation LTE) technology has following two unique functions so that ANR functions turn into May：

(1), the user equipment in LTE technical systems (User Equipment, abbreviation UE) measurement configuration does not need adjacent area List, the unknown adjacent area that UE energy automatic detections go out on corresponding frequency, and measure and report the speed of unknown cell sufficiently fast, can be Cell switching is prepared.So, even if the unknown cell is the miss-configured neighboring cells of serving cell, ANR functions can also make UE small at this Handover measurement is performed in area.

(2), for the unknown cell detected, base station (eNodeB) can control UE to perform cell global identity (Cell Global Identity, abbreviation CGI) is measured, so as to thoroughly identify the unknown cell, for use in adjacent area is established Relation.

ANR functions in LTE technologies can will in time find other adjacent areas with covering with LTE cells, and in order to support this Function, agreement is supported to allow LTE UE periodically to report the best cell of signal, is embodied in LTE protocol, is specially：

(1), measurement reports the support purpose of configuration to be：ReportStrongestCells (reporting most strong cell) and ReportStrongestCellsForSon (reporting most strong cell for SON) period measurement, the measurement for such purpose are matched somebody with somebody Put, UE can report the cell detected.

(2), measurement reports the support purpose of configuration to be：ReportCGI (reporting CGI) period measurement.

(3), support that configuring transmission flow (eNB/MME CONFIGURATION TRANSFER) by S1 obtains adjacent area institute In eNodeB IP address, to establish the X2 connections between base station automatically.

The schematic diagram of neighboring BS relationship is established in LTE standards shown in Figure 1, is comprised the following steps：

(1), the base station of from UE to cell A are reported comprising Physical Cell Identifier (Physical Cell Identity, abbreviation PCI nearby region measurement report), it is assumed that PCI=5, represent adjacent cell B；

(2), cell A inquires about its adjacent area table, it is found that PCI=5 is unknown；

(3), cell A reconfigures to UE, to notify UE to read cell B CGI；

(4), UE reads CGI from cell B broadcast, and reports cell A, and cell A has found that cell B can be added as neighbour Area, then increase and cell B neighboring BS relationship, such UE may be switched to cell B from cell A；

(5), cell A base station checks whether the X2 connections for allowing to establish to base station where cell B；

(6), cell A base station by S1 configure transmission flow or from domain name system (Domain Name System, letter Claim DNS) IP address of base station where acquisition cell B；

(7) the X2 connections, established by IP address between cell A base station and cell B base station；

(8), cell A base station sends cell status change information and gives operation maintenance center (Operation and Maintenance Center, abbreviation OMC).

In addition, UE in the lte networks when, LTE cells and other different systems (such as GERAN/UTRAN) cell establish adjacent area Attribute of a relation flow is similar with above-mentioned flow, and difference is：

(1) it is, different for different different grids, cell ID.

(2) the X2 connections that, need not be established between base station, i.e. above process step (5)~(7) are not deposit for different system ANR .

But for 4G LTE/LTE-A networks, when base station autonomous control terminal carries out ANR measurements, if control strategy It is improper, then it may find to cause cell to switch call drop not in time because of neighboring BS relationship, so as to cause poor Consumer's Experience.

Embodiment

To make the purpose, technical scheme and advantage of the embodiment of the present invention clearer, below in conjunction with the embodiment of the present invention In accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is Part of the embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art The every other embodiment obtained under the premise of creative work is not made, belongs to the scope of protection of the invention.

In the embodiment of the present invention, LTE base station can control the UE for meeting certain condition, being linked into LTE network, service UE Scan task is performed on the outside frequency (including LTE and other standards) of frequency or serving cell where cell, the scanning Task measures for ANR.Once UE scans new cell, base station can make decisions, when new cell meets that condition newly cell will add Enter neighborhood region correlation chart (Neighbor Relation Table, abbreviation NRT) to establish neighboring BS relationship.Base station ANR functions are just opened When, when finding more new cell, more intensive ANR will be performed and measured, to establish required neighboring BS relationship in time.Cross After a period of time, the outside adjacent area of serving cell is all found substantially, and base station should make UE as few as possible perform ANR measurements. But even if for a long time without new cell is found, base station also must retain necessary, bottom line ANR in each cell and survey Amount acts, to find the change of network in time.

The embodiment of the present invention gives different system ANR measuring methods, and lower mask body introduces different system ANR measuring methods.

It is the schematic flow sheet of the measurement control method of different system adjacent cell relation provided in an embodiment of the present invention referring to Fig. 2, This method comprises the following steps：

Step 201：If terminal device is in radio resource control RRC connected state with base station, and the terminal device has The condition of Automatic Neighboring Relation ANR measurements is performed to different system, then the first measurement position that the base station selected terminal device is supported To put, first measurement position is the first frequency or first frequency group, wherein, described first surveys in current first setting time The actual ANR measurement reports quantity that receives is less than current desired ANR measurement reports quantity on amount position, the different system for The different network system of the terminal equipment access network system, the terminal equipment access network system are LTE standards.

Wherein, the terminal device is LTE UE, and the base station is LTE eNodeB, and the different system can be that code division is more The network or GSM/EDGE cordless communication networks of location (Code Division Multiple Access, abbreviation CDMA) system (GSM EDGE Radio Access Network, abbreviation GERAN), wherein, the network of CDMA systems can be UTRAN (Universal Terrestrial Radio Access Network, Universal Terrestrial wireless access network) or CDMA2000 etc..

LTE eNodeB can establish neighboring BS relationship using LTE UE measurement function come each cell with different system.Equally The action of control ANR measurements can be divided into active ANR and passive ANR, wherein, passive ANR is i.e. in conventional mobility measurements mistake ANR is acted caused by unknown adjacent area is found in journey；Active ANR is that base station can press when LTE network uses active ANR functions Actively control UE according to certain strategy, allow UE scanning resident service cell service frequency and adjacent external frequency, so as to and When detect the adjacent external cell (different system) of resident service cell, and further read CGI, determined according to certain rule be It is no to establish neighboring BS relationship.

Minimum to service impact in order to ensure, only selection meets that the UE of certain condition carries out ANR measurements, when LTEUE is initial When accessing network or being switched to purpose cell, when the condition of ANR measurements can be performed to different system below LTE UE meet, The related Physical Cell Identifier PhysCellId measurements of ANR can be performed to report：

(1), UE does not send or received data.

That is, UE is in RRC connected states but does not send or receive data, and this state is referred to as non-traffic activated state, and one Denier UE needs carry out business, and base station controls the UE to stop ANR measurements at once.

(2), UE has the ability for reading cell global identity CGI.

(3), UE supports to access the wireless access technology of the different system.

(4), UE supports the frequency range for performing ANR measurements.

(5), when the different system is UTRAN, UE has the ability that period measurement is carried out in unknown UTRAN cells, And support to find that the unknown UTRAN cells are that self-organizing self-optimizing network measurement reports most strong cell (report Strongest Cells For SON) measurement configuration；When the different system is CDMA2000, have unknown The ability of period measurement is carried out in CDMA2000 cells, and support for find the unknown CDMA2000 cells be self-organizing oneself Optimization network measure reports the measurement of most strong cell (report Strongest Cells For SON) to configure.

(6), when the different system is GERAN, there is the ability that period measurement is carried out in unknown GERAN cells, and Support to find that the unknown GERAN cells report the measurement of most strong cell (report Strongest Cells) to configure.

In the present embodiment, frequency/group of frequencies where serving cell and serving cell outside frequency/group of frequencies configuration are true Measurement frequency point/the group of frequencies for being used for ANR measurements is determined.For each measurement frequency point/group of frequencies, base station real-time tracking frequency herein The ANR measurement report quantity that all terminals of ANR measurements report is performed in point/group of frequencies, within a certain period of time (such as per small When), if the ANR measurement reports quantity that base station it is expected to receive is more than the ANR measurement report quantity actually received, base station will persistently match somebody with somebody Put UE and perform ANR measurements.In order to reduce the influence to performance, meet that the UE of condition is only performed in a frequency/group of frequencies ANR measurement.In order to ensure the fairness of ANR measurements in frequency/group of frequencies, for each frequency/group of frequencies, according to a timing The expectation ANR measurement reports quantity and difference row's priority of actual ANR measurement reports quantity that interior base station receives, that is, define certain Expectation ANR measurement report quantity in individual frequency/group of frequencies subtracts actual ANR measurement reports quantity as the frequency/group of frequencies Weight, the bigger frequency of weight/group of frequencies priority is higher, and vice versa.Frequency/group of frequencies of highest priority preferentially obtains UE measures to perform ANR；When UE does not support certain frequency/group of frequencies, lower priority frequency/group of frequencies that UE is supported is selected to hold Row ANR is measured.Based on the above, in step 401, the first survey that the terminal device can be selected to support in the following manner Position is measured, wherein, first measurement position is the first frequency or first frequency group：

It should be noted that first measurement position refers to some survey in all measurement positions that terminal device is supported Position is measured, first frequency refers to some frequency in all frequencies that terminal device is supported, the first frequency group refers to Some group of frequencies in all group of frequencies that terminal device is supported, that is to say, that " first " and not comprising phases such as any " orders " Close implication.

It should be noted that in order to perform the different system frequency point information/frequency group information in the outside of active ANR, LTE cell (different system frequency relation) needs to configure in advance.Assuming that first setting time is 1 hour, then for each different system frequency Point/group of frequencies, the pendulous frequency per hour that receives and the last ANR it is expected in each frequency/group of frequencies of base station real-time tracking UTRAN either ANR CDMA2000 or ANR GERAN measurements, the object time point of ANR measurements next time is calculated accordingly.It is next After secondary time of measuring point arrives, as long as there is UE to enter non-traffic activated state, base station controls it to perform related ANR measurement tasks in time.

In order to reduce the influence to performance, meet that the UE of condition is only performed in a UTRAN frequency or one ANR measurements on CDMA2000 frequencies or a GERAN group of frequencies.Frequency/group of frequencies of highest priority preferentially obtains UE To perform ANR measurements；When UE does not support certain frequency/group of frequencies, lower priority frequency/group of frequencies that UE is supported is selected to perform ANR is measured.

Step 202：Base station is the metering system that the terminal device selects the ANR measurements, and according to the measurement side Formula initiates the 3rd RRC connection reconfiguration courses, think that the terminal equipment configuration carries out in first measurement position described in Radio Resource needed for ANR measurements.

As it was previously stated, passive ANR is based on conventional mobility measurements, active ANR is user's active control, to upgrade in time Measurement for the purpose of neighboring BS relationship.

For the network (such as UTRAN and CDMA2000) of CDMA systems, the uncontrollable UE in base station is based on mobility measurements Report and detect unknown cell, i.e., uncontrollable UE performs passive ANR measurements, but UE can be controlled to perform active ANR measurements. As described in 3GPP TS36.331, in order that UE is measured by active ANR to find unknown UTRAN cells or unknown CDMA2000 Cell is, it is necessary to control UE to carry out purpose as " report Strongest Cells For SON " period measurement, now max Report Cells (measurement reporting subdistrict maximum number) are arranged to 1, report Amount (reporting quantity) and are arranged to r1.UE is received To this measurement configuration, start measurement, after most strong cell is being measured on related frequency, report most strong cell.Given Time in, the UE for accessing this LTE cell has to carry out the maximum times user of this measurement and can configured.

For GERAN networks, it is similar with LTE network, and base station can control UE to be reported based on mobility measurements and detect Unknown cell, you can measured with controlling UE to perform passive ANR, UE can also be controlled to perform active ANR measurements.Such as 3GPP Described in TS36.331, in order that UE is measured by active ANR to find unknown GERAN cells, can carry out purpose is " report Strongest Cells " period measurement.UE receives this measurement configuration, starts in related GERAN group of frequencies and surveys Amount.UE assesses the cell measurement results on all frequencies, reports most strong cell.Within the given time, this LTE cell is accessed UE have to carry out the maximum times user of this measurement and can configure.For GERAN, can also use based on event triggering ANR is measured, and user can select which kind of control mode used, only for GERAN, it is necessary to select RRC according to user configuration Measurement connection is matched somebody with somebody again in is configured, if the ANR measurements that user's selection is triggered using event, event need to be configured to by measuring to match somebody with somebody again The ANR measurements of triggering, number is reported more than untill configured threshold until measuring full regular hour or measurement.

In order to quickly find outside adjacent area, it is possible to use only active ANR, or passively both measurements of ANR and active ANR Control strategy is carried out simultaneously.Therefore, in step 202, when the network system of terminal device access is LTE system and described When different system is UTRAN or CDMA2000, the metering system of ANR measurement is active ANR metering systems, the active ANR Metering system is periodic measurement mode；When the network system of terminal device access is LTE system and the different system is During GERAN, the metering system of the ANR measurements is that the metering system that active ANR metering systems or the ANR are measured is passive ANR metering systems and active ANR metering systems, the active ANR metering systems are the metering system or periodicity of event triggering Metering system；Wherein, the passive ANR metering systems are that the terminal device detects the clothes during mobility measurements The mode of the adjacent cell for cell of being engaged in, the active ANR metering systems are that the terminal device detects according to the control strategy of base station Go out the mode of the adjacent cell of the serving cell.

In step 202, when the active ANR metering systems are specially the metering system of event triggering, base station can be with RRC connections are carried out to terminal device to reconfigure, and make the ANR measurements again with measurement support event triggering, it is waiting to receive terminal device When the RRC connections of transmission reconfigure completion message, configuration successful is determined；When the active ANR metering systems are specially periodically During metering system, base station can carry out RRC connections to terminal device and reconfigure, and make to support periodicity ANR measurements with measurement again, treat The RRC connections of terminal device transmission are received when reconfiguring completion message, determine configuration successful.Wherein, in periodicity ANR measurements The configured measurement purpose of report includes：Report Strongest Cells (reporting most strong cell) and Report Strongest Cells For Son (report most strong cell) for SON.

Step 203：When receive that the terminal device reports in first measurement position marks comprising physical area After the ANR measurement reports for knowing PhysCellId, whether understood according to the cell representated by the PhysCellId come described in updating Current desired ANR measurement reports quantity.

In step 203, for UTRAN-FDD, PhysCellId is scrambler (scramble code)；For UTRAN-TDD, PhysCellId are intermediate code (midamble codes)；For GERAN, PhysCellId is BSIC (Base Station Identity Code)；For CDMA2000, PhysCellId is that PN biases (PN Offset).

In the embodiment of the present invention, only frequency/group of frequencies (measurement position) is configured to support active ANR measurements, base station Just consider to start corresponding measurement operation in this frequency/group of frequencies.The result dynamic that base station can report according to actually measuring is managed The ANR measurement report quantity received in each measurement frequency point/group of frequencies is managed, is specially：

(1), base station is it is expected that the ANR measurement report quantity received is set (in the first setting time) in each measurement position Maximum and minimum value are put, wherein, when the different system is UTRAN or CDMA2000, the measurement position is the terminal The frequency of equipment access service cell or the outside frequency of the serving cell, when the different system is GERAN, the measurement Position is the group of frequencies of the terminal device access service cell or the foreign frequency group of the serving cell；Establishing or restarting During the serving cell, the ANR measurement reports quantity for it is expected to receive in each measurement frequency point in the first setting time is set For the maximum.

Specifically, divide RAT (Radio Access Technology, wireless access technology), be respectively each measurement frequency The ANR measurement report quantity for it is expected to receive in point/group of frequencies sets up maximum and minimum value.Wherein, the first setting time can be with It it is 1 hour or other time length.

(2), assume that first setting time is 1 hour, then in each measurement frequency point/group of frequencies, when base station is found When in measurement report (either active ANR measurements or passive ANR measurements) containing recognizable PhysCellId, if now It is all known cell that continuously a period of time or continuous certain number, which have received the ANR measurement reports content reported, then divides RAT reduces the ANR measurement report quantity for it is expected to receive in corresponding frequency/group of frequencies per hour, until being reduced to the minimum value Untill；When finding to contain unidentified PhysCellId in measurement report (either active ANR measurements or passive ANR measurements) When, the ANR measurement report quantity for it is expected to receive per hour can be divided in the corresponding frequency/group of frequencies of RAT increases, until increasing to initial Untill it is expected ANR measurement reports quantitative value (i.e. maximum).It should be noted that because a lot of UE may not possess measurement and read CGI ability does not support corresponding RAT and frequency/group of frequencies, so, it is expected ANR measurement report numbers although can configure The minimum value of amount, but the measurement report that the UE of actual participation measurement is reported is likely lower than this minimum value.Based on above-mentioned interior Hold, in step 203, it is described current desired to update whether base station understands according to the cell representated by the PhysCellId ANR measurement report quantity, concrete operations are as follows：

It is (i.e. continuous in current second setting time if the cell representated by the PhysCellId is known cell In a period of time) and the cell that is reported of all ANR measurement reports for being received in first measurement position be known small The cell that area or current continuous setting number and all ANR measurement reports received in first measurement position are reported When being known cell, then the ANR measurement report quantity for it is expected to receive in first measurement position is reduced, after the reduction It is expected that ANR measurement reports quantity is not less than the minimum value；If the cell representated by the PhysCellId is unknown cell, Increase the ANR measurement report quantity for it is expected to receive in first measurement position, the expectation ANR measurement report numbers after the increase Amount is not more than the maximum.

Step 204：If reach first setting time or ANR measurement report numbers that the terminal device reports exceed Predetermined threshold value, then the 4th RRC connection reconfiguration courses are initiated to be released to the carry out of the terminal equipment configuration ANR surveys Radio Resource needed for amount, if the ANR measurement report numbers that not up to described first setting time or the terminal device report Not less than predetermined threshold value, then described the step of 3rd RRC connection reconfiguration courses are initiated according to the metering system is performed.

When the different system is GERAN, there is the ability that period measurement is carried out in unknown GERAN cells, and support To find that the unknown GERAN cells report the measurement of most strong cell (report Strongest Cells) to configure.

Step 303：ENodeB selects frequency/frequency that UE is supported, that weight is maximum from all measurement frequency point/group of frequencies Group, working frequency points/group of frequencies of ANR measurements is carried out as UE.

Step 304：ENodeB judges the weighted value of selection frequency/group of frequencies (in the frequency/group of frequencies, in certain time The ANR measurement report quantity for it is expected to receive subtracts the difference obtained after the ANR measurement report quantity actually received) whether it is more than 0, If it is, step 305 is performed, if it is not, then terminating flow.

Step 305：Open ANR measurement timers.

Step 306：ENodeB carries out RRC connections to UE and reconfigured so that UE supports ANR measurements.

When the network (such as UTRAN and CDMA2000) that different system is CDMA systems, make to support periodicity ANR with measurement again Measurement, when different system is GERAN networks, make the ANR measurements for supporting periodicity ANR measurements or event triggering with measurement again.

Step 307：After UE completes to reconfigure, send RRC connections to eNodeB and reconfigure completion message.

Step 308：ENodeB waits UE ANR measurement reports.

Step 309：UE reports ANR measurement reports to eNodeB.

Step 310：ENodeB updates the measurement report number that the UE is reported, and number is added 1.

Step 311：Whether PhysCellIds of the eNodeB in ANR measurement reports be unknown, updates corresponding frequency/frequency The ANR measurement report quantity received it is expected in group.

Step 312：ENodeB judges whether the ANR measurement reports number that the UE is reported exceeds threshold value or the survey of the UE Whether overtime timer is measured, if it is, step 313 is performed, if it is not, then performing step 306.

Step 313：ENodeB carries out RRC connections to UE and reconfigured, and discharges related resource so that UE is no longer supported periodically ANR is measured or the ANR measurements of event triggering.

Step 314：After UE completes to reconfigure, send RRC connections to eNodeB and reconfigure completion message.
