Description

A kind of measurement report report method and equipment

Technical field

The present invention relates to communication technical field, particularly a kind of measurement report report method.The present invention also relates to a kind of base station simultaneously.

Background technology

At present, RNS (Radio Network Subsystem, RNS) RRM (the Radio Resource Management of network, RRM) according to NODE (node) B and UE (User Equipment, subscriber equipment) the various metrical informations that report take various algorithm as much as possible anti-interference, promote network capacity, meet the Qos demand of miscellaneous service, the prerequisite that wherein algorithm is correctly implemented be various measured value timely, accurately report.From the angle of network optimization, operator needs to gather MR (Measurement Report, measurement report) data (according to agreement TS25.123), content in the measurement report that tracking NODEB and UE reports, these contents comprise RSCP (the Received Signal Code Power of up-downgoing wireless link, received signal code power), ISCP (Interference Signal Code Power, Interference Signal Code Power), BLER (Block Error Ratio, bLock error rate) and the information generating report forms such as transmitting power be used to guide the analysis network coverage, capacity and structure are also located network problem, the MR data on these bases are that operator provides foundation to network performance evaluation and optimization.RRM algorithm relies on to be measured the promptness that reports and requires (measuring period is short and report in time) and utilize the data-optimized and planning network of magnanimity MR, CDL (Call Detail Log, call log) counter KPI (Key Performance Indicator, KPI Key Performance Indicator) reports proposition requirements at the higher level to NODEB measurement.

As shown in Table 1, wherein contain current RNC (Radio Network Controller, radio network controller) equipment RRM and MR and KPI statistical requirements NODEB report public-measurement classification, the measurement application target that RNC needs NODEB to report divides three classes, one class is that RRM algorithm uses, and the measurement that RRM algorithm needs only reports when algorithm is opened and reports and requires in time (existing network not all algorithm is all opened).One class is that the CDL of the counter needs that KPI is corresponding measures, and equipment runs to be opened in real time.One class is that operator carries out the MR needs of the network optimization and assessment, and MR unlatching usually will be opened 7 days (comprising+2 all doomsdays of 5 working days) continuously or is carry out in the cycle opening (the UE measurement that MR comprises, RNC internal measurement, NODEB special measurement and publicly-owned measurement with the moon.Measure report cycle for NODEB and be generally 2 seconds or 8 seconds.Verify at existing network: under identical configuring condition, changed ISCP and TXP into 2 seconds periodic reports by 8 second cycle, CPU usage on average rises 7%, illustrates that measuring period has taken considerable influence to CPU.Current Large Copacity RNC configure NODEB substantially all at about 500, CELL number about about 1500, the public-measurement number of needs is 1500*3 bar (public-measurement does not carry TS information, measures mark 1,2,3, reports regardless of carrier slots).Maximum on-line UE number 25700 simultaneously, special measurement number is (25700* measures type) bar about, and such as RRM algorithm is opened needs measurement to be designated 2,3,4,15,19, and special measurement number reports 25700*5 bar.Within very short period, a large amount of measurement message is reported to cause RNC CPU (Central Processing Unit, central processing unit) sharply rise violently, after CPU raises, can produce load alarm, RNC enables load curtailment strategy automatically, comprise and carry out RRC connection refusal in certain proportion, forbid switching into etc., have deleterious effects to relevant KPI index, and can selective intake process be carried out to the measurement data reported.Agreement specifies: RNC a to NODEB only has 1 NCP (NodeB Control Port, NodeB control port), but can have multiple CCP (Communication Control Port, connection control port).The link of carrying NCP and CCP can be SCTP/SAAL link (Stream Control Transmission Protocol: SCTP, corresponding IP base station.Signaling ATM Adaptaion Layer:ATM adaptation layer signaling, corresponding atm base station).Public-measurement report is reported by NODEB control port NCP, and special measurement is reported by communication control port CCP and distinguishes UE by CRNCCID (CRNC Communication Context ID) and NBCC (NodeB Communication Context).Therefore, in a large amount of message of measuring by NCP and CCP gives the correct time, cause the congested and processing delay of NCP and CCP signaling link to increase.Therefore, in the urgent need to a kind of method solve measure message a large amount of on IUB signaling link on to give the correct time the control method and strategy that reduce machine utilization.

Based on above situation, control NODEB method that is public and special measurement report has following several at present:

The strategy of scheme one, most equipment supplier is, opens MR or before measuring, adds up busy (obtaining by local busy) machine utilization average within the next few days, during lower than certain safe threshold, can open MR and measure.If all the time higher than threshold values, open after needing to carry out load balancing, load equalization method comprises cutover base station or increases hardware board again.

Scheme two, to be widened measurement report cycle that MR and CDL need by data configuration or close inessential measurement.

Scheme three, by supervisory control system resource overhead (CPU and internal memory etc.), dynamic conditioning is measured report cycle and is also forbidden or open new measurement.

Scheme four: agreement supports that public-measurement cancels sub-carrier, time-division slot reports, and once can report the metrical information of multiple frequency and time slot.

Realizing in process of the present invention, inventor finds that above four kinds of schemes also exist following deficiency respectively:

Scheme one is when opening special algorithm, starting MR or CDL measurement, need to assess the busy hour load of RNC, if during higher than safe threshold, need to adopt base station cutover to carry out equalizing traffic volume, CPU etc. is reduced to below safe threshold and could opens particular measurement, during cutover, cause service disconnection and human cost waste.When load cannot reduce, need to carry out dilatation board and carry out Traffic Distribution, cause hardware resource waste and RNC cost to improve.

Scheme two, three difference be whether RNC automatically widen or people for widening measuring period and closing inessential measurement.Two schemes all needs to analyze the priority of the measurement that various algorithm needs, and widen merely and cause measuring period measured value to report delay, the measurement causing RRM algorithm to need is inaccurate causes the whole and MR measurement data non-dense set collection of algorithm mistuning thus precisely can not reflect the objective looks of network.

Although scheme four solves the problem of public-measurement sub-carrier and time slot, a large amount of public-measurement message can be reduced, also need a point measurement type to carry out measurement and report.And to special measurement, be directly correlated with on-line UE number, can not all problems be solved.

Therefore, how public-measurement information reporting mechanism is optimized, to reduce operating load and the performance pressures of RNC, becomes the technical problem that those skilled in the art are urgently to be resolved hurrily.

Summary of the invention

The invention provides a kind of measurement report report method, in order to report mechanism to be optimized to measurement report, reduce the load of network equipment, the method comprises:

Embodiment

As stated in the Background Art, at RRM algorithm, when MR gathers switch open and index counter requirement collection particular measurement, base station periodically part-frequency point time-division slot divides measurement type to report public-measurement report or report special measurement reporting message for RL, in UE access situation in a large number, at NCP (NodeB Control Port, base station control port) and CCP (Communication Control Port, interactive controlling port) link reports that a large amount of measurement report message causes RNC and base station equipment board to there is a large amount of message bursts and forwarding, machine utilization such as CPU usage continues high-order running, equipment performance declines, equipment delay machine paralysis probability increase.Therefore the present invention is by optimizing public-measurement information reporting mechanism, proposition is connected in series the measurement message of RRM algorithm needs based on SFN and the CFN moment and use measuring period (file transfer protocol (FTP), File Transfer Protocol), File Transfer Protocol uploaded MR and CDL needs MR file to MR server and north orientation server by widening.

As shown in Figure 1, be the schematic flow sheet of a kind of measurement report report method that the present invention proposes, comprise the steps:

S101, base station obtains the type and measurement demand measured, and described measurement demand comprises: need to open RRM algorithm, need to open MR and need to open CDL.

Before this step, first classify according to measurement demand object, described base station obtains the current all public-measurement relevant to self and special measurement; Described base station determines the corresponding measurement demand with each described public-measurement and special measurement respectively; Described base station is recorded and is stored the measurement demand of each described public-measurement and special measurement.In concrete application scenarios, the classification of NODEB public-measurement and special measurement classification are respectively as shown in following table 2, table 3.

Table 2. base station public measurement classification chart

Table 3. base station special measurement classification chart

Based on above classification chart, to the measurement of RRM algorithm, MR, CDL common need, because the ageing of RRM algorithm requires that measurement report is reported to RNC to carry out decision-making in time, therefore, preferentially take to carry out in information reporting mode on NBAP link with RRM algorithm requirements to this type of measurement report.To the measurement that non-RRM algorithm needs, ageing strong, but require intensive extraction for network optimization or measure for positioning problems object can by ftp file reporting schemes.

Although it is pointed out that the present invention proposes different control methods in subsequent step, these control methods can be used alone also can be with the use of.Such as: do not start ftp server function by means of only message tandem, or when size of message forward rate acquires a certain degree, congested and interface board is busy with processing and measures the problems such as CPU usage that message causes is high with point high IUB signaling link caused of flow message forward rate to restart ftp server function.Therefore, after described base station is recorded and is stored the measurement demand of each described public-measurement and special measurement, when described base station is determined to need reporting measurement reports according to described measurement, described base station obtains current size of message forward rate, and judges that whether described size of message forward rate is higher than the threshold value preset; If so, the type and the measurement demand that obtain described measurement are continued in described base station; If not, described base station reports to described RNC after being connected in series by described measurement report.

S102, if confirm, described measurement needs to open RRM algorithm and for public-measurement, described base station reports to RNC according to the coded format of specifying by NCP port by with described measurement after corresponding multiple measurement reports are connected in series.

S103, if confirm, described measurement needs to open RRM algorithm and for special measurement, described base station reports to described RNC according to the coded format of specifying after being connected in series by the measurement report of the UE by identical CCP port.

Inventor is realizing finding by measuring NODEB to cancel after sub-carrier analysis time slot is verified in process of the present invention, if comprise multiple measurement item at a measurement report, very micro-on CPU usage impact, illustrate that the number relation of CPU usage and measurement report message is comparatively large, and in measurement report, the number of measurement result is substantially irrelevant.Therefore, for reducing information reporting number and compatible protocol, the present invention is directed to the public-measurement that RRM algorithm needs, RNC can be reported to by NBAP agreement ASN.1 coded format by after multiple measurement report serial connection on NCP port.For the special measurement that RRM algorithm needs, after the measurement report of the UE on identical CCP port can being connected in series, be reported to RNC by NBAP agreement ASN.1 coded format, to reduce measurement report quantity.

Particularly, when occurring needing to carry out concentrating situation about reporting, as follows with the concrete processing scheme corresponding to S102 and S103:

(1) need to open RRM algorithm and for public-measurement

Described base station to be carried at SFN in universal measurement initiating request message for initial time, after the measurement report of the UE by identical CCP port is connected in series according to the coded format of specifying and periodic report to described RNC; SFN value between different base station is determined in the span preset according to the Base Station Identification ID of current base station.

(2) need to open RRM algorithm and for special measurement

Described base station to be carried at CFN in special measurement initiating request message for initial time, after the measurement report of the UE by identical CCP port is connected in series according to the coded format of specifying and cycle report to described RNC; SFN value between different base station is determined in the span preset according to the Base Station Identification ID of current base station; CFN determines in the span preset according to the difference between described SFN and default frame shifting amount.

S104, if confirm, described measurement does not need to open RRM algorithm, corresponding measurement report is measured with the form buffer memory of MR file among self by with described in described base station, and is connected described MR files passe under the particular category of described RNC by FTP when arriving predetermined period.

The public-measurement that network optimization (MR and CDL) is needed and special measurement, generally report RNC by NODEB by signaling link, the form that RNC presses MR server and north orientation server needs generates MR file, by north orientation server parses MR file, according to the metrical information reported carry out analyzing for assessment of and optimized network.This type of ageing and promptness measured requires not harsh, the measurement that therefore can need with RRM algorithm separately, adopt File Transfer Protocol upload file mode instead of transmit on IUB mouth signaling link, saving IUB message and make link bandwidth and reduce RNC handling property pressure.

Correspondingly, when needing that when not needing unlatching RRM algorithm concentrated carrying out is given the correct time, concrete mode is as follows:

The SFN moment point that the address pool numbering poll that described base station notifies according to described RNC is corresponding with different time sections; When described base station judges that arrival numbers corresponding SFN moment point with described address pool, described base station is set up described FTP and is connected and upload described MR file within the repetition period corresponding with described SFN moment point; Wherein, described address pool numbering is determined after the IP address of current all distribution base stations is divided into different address pool according to FTP connection base station batch by described RNC, and described FTP connects base station batch and determined according to the number of described distribution base station and the maximum FTP linking number can set up simultaneously by described RNC.

In concrete application scenarios, two kinds of transmission mode base stations are below divided to carry out FTP function declaration:

(1) ATM base station

ATM base station is when starting, special I POA passage and application IP address is set up by default VPI/VCI default channel, RNC distributes corresponding PVC and IP address, and response is sent to Node B on the passage of acquiescence, response message comprises the IP of RNC, the IP of Node B, subnet mask, the information such as the IP of the IP of FTP SERVER, SNTP SERVER.Special I POA passage is set up in the binding that Node B completes the corresponding relation of PVC and IP, uses FTP to download related software and configuration file from FTP_server.Node B starts the software downloaded afterwards, and the configuration file that use is downloaded completes the initial configuration to software.

(2) IP base station

ARP message, when self-starting powers on, is monitored in IP base station, and dhcp process is initiated in base station, RNC by dhcp process to base station assigns IP address.Base station utilizes the IP address of RNC side in the IP address and DHCP message distributed to set up OM passage, transformation parameter configuration file is applied for RNC, RNC in the response message signals base configuration file deposits path, login username, the information such as password and FTP SERVER address.After base station receives message, utilize the information obtained to initiate FTP process, obtain corresponding configuration file, after getting profile information, complete software initial configuration.

Can find out based on above flow process, when IUB interface transmission configuration is ATM or IP mode, FTP SERVER function all can be started in RNC side, base station is as ftp client, connect with RNC side ftp server in passive mode, by the upload file of FTP mode high efficient and reliable to RNC or from RNC download file.Correspondingly, for the measurement that MR and CDL needs, the present invention is MR file at NODEB side temporary cache, under utilizing large cycle to be uploaded to the particular category of RNC by FTP mode, reduce the NBAP Message Transmission mode of NODEB and RNC side and save the processing procedure of RNC and NODEB both sides NBAP agreement ASN.1 encoding and decoding, reduce CPU usage, the measurement report link circuit resource of NCP and CCP being left for ageing strong RRM algorithm needs uses, and alleviates the performance pressures of RNC.

In order to set forth technological thought of the present invention further, now in conjunction with concrete application scenarios, technical scheme of the present invention is described.

One, adopt serial connection to measure message the ageing measurement report requiring harsh RRM algorithm to need to report by the mode of NBAP agreement ASN.1 coded format

For avoiding occurring that moment that multiple base station measurement report concentrates on a Relatively centralized reports the situation of RNC, therefore under needing control RNC, the measurement report at multiple station staggers at times as far as possible and reports, and proposes in public-measurement initiating request message, carry optional IE:SFN (System Frame Number of the cell).After agreement carries this IE, base station reports for starting point starts to carry out periodic measurement report with this SFN.The value of SFN is that under (CELLID*10) MOD 4096, RNC, CELLID does not repeat, the therefore public-measurement reporting occasions at different station dispersion as far as possible, and the report of alleviation different base station public-measurement is concentrated and sent.Owing to taking advantage of the process of 10 to community ID, report to have the interval of 100ms the opportunity of public-measurement between a Zhan Sange community, under therefore also avoiding same base station, the impact reported base station performance is concentrated in different districts public-measurement report.Such as the ID of three communities, a base station is 59631,59632,59633 respectively, the SFN of these three communities in COMMON MEASUREMENT INITIATION REQUEST respectively: 2390,2400,2410.Therefore, based on SFN, can be dot cycle in the different SFN moment report public-measurement to arrive at RNC cause message bursts to avoid measuring in a large number message synchronization at NCP port to multiple NODEB.And multiple CELL can report the public-measurement of different measuring type to report by difference 100MS under identical NODEB, the polymorphic type measurement report of identical CELL can adopt tandem to report at NCP public port.

In addition, for special measurement, the present invention then carries optional IE:CFN (Connection Frame Number for the radio connection) in special measurement initiating request message.After carrying this IE, base station with this CFN for starting point starts to carry out periodicity special measurement report reporting.The following CFN=of corresponding relation (SFN-Frame Offset) mod 256 of SFN and CFN is held at UTRAN, Frame Offset scope is 0 ~ 7, different UEs configures different Frame Offset, CFN just has difference, and the benefit brought so balanced Iub interface can concentrate the load reported at special measurement report.For multiple UE, with different CFN moment point for starting point periodic report measurement report.The polymorphic type special measurement report of same UE can be connected in series and report, if different UEs report cycle overlaps, the special measurement report of the many UE on identical CCP port also can be connected in series and report.Being connected in series the message reported utilizes the reserved field of NBAP agreement to represent, the message header after serial connection defines according to the ASN1 coded format of NBAP agreement.(namely adopting the alignment pattern of ASN1 to encode).Utilize agreement to retain 255 as the message number of concatenateable message, and the coding of concatenateable message head meets the ASN.1 coding rule of NBAP protocol byte alignment, need not revise agreement, compatible RNC and NODEB new and old edition.Take new paragon (serial connection and the SFN moment of diverging to) or old reporting schemes (cycle non-serial connection) by RNC informing base station in the self-starting process of base station and notify maximum concatenateable message number.

Particularly, NBAP agreement ASN.1 coding rule describes as follows:

CHOICE type ASN.1 is encoded to 3 bit, and a bit represents whether select extension flag, utilizes 2bit to represent News Category.Such as SuccessfulOutcome message coding is: 001.InitiatingMessage is defined as follows:

Message Discriminator is defined as follows shown in table 4:

Table 4

In upper table, Message Discriminator coding takies 1 bit, Criticality coding and takies 2 bit.Correspondingly, Transaction ID is defined as follows shown in table 5:

Table 5

Transaction ID type selecting Short or Long in upper table, coding takies 1 Bit.Short Transaction ID takies 1 byte, and long Transaction ID takies 2 bytes.And Procedure Code coding takies 1 byte in Message Type, Ddmode takies 3 bit, shown in table 6 specific as follows:

Table 6

Public-measurement report message content is as follows:

Special measurement report message content is as follows:

Based on above explanation, as shown in Figure 2, front 5 bytes of ASN1 coding are " 00084a 0000 " to concrete CommonMeasurementReport message instance, and corresponding is described as follows:

First byte: 00

0-------NBAP-PDU finally has extension, this 0 indicate without expansion.

-00-----NBAP-PDU is choice, and has four, and these two 0 represent that select is Section 1 InitiatingMessage.

---00000 fill out to align 0.

Second byte: 08

The type of 08 this PDU of expression: " 8 "=Common Measurement Report, takies a byte.

3rd byte: 4a.

010-----represents that ddMode is common, and first bit 0 represents extension flag position.10=2 represents Common.

---01---represents that Criticality is Section 2 ignore.

-----0--represents that Message Discriminator is Common.

------1-represents that transactionID is Long.

-------0 aligns fill out 0.

The length of the value of 00010000 whole InitiatingMessage.

0-------represents that CommonID does not have spreading parameter.

-0------represents that first optional parameters of CommonID does not have.

--000000 is align fill out 0, represents that fourth, fifth byte is Transaction ID Value.

6th byte and be concrete message coding length and content with postbyte.

Based on the ASN.1 coding rule of above-mentioned NBAP_PDU, define and report serial connection public-measurement message format as shown in table 7 below from NCP port, wherein the 2nd byte is defined as " 255=Serail Measurement Report.Other code field implications do not change.

Table 7

For special measurement report message DedicatedMeasurementReport, be that Message Discriminator is dedicated with CommonMeasurementReport Messages Message difference, therefore, define and report serial connection special measurement message format two as shown in table 8 below from CCP port, wherein the 2nd byte is defined as " 255=Serail Measurement Report.Other code field implications do not change.

Table 8

Base station is when supporting tandem, and same CELL identical reports the eurypalynous public-measurement report in moment to take above message format 1 to be connected in series and report at NCP port.Multiple UE of same CELL identical reports multiple special measurement report on the identical CCP port in moment to take message format 2 to be connected in series and reports at CCP port.Concatenateable message head meets the ASN.1 coding criterion of NBAP_PDU.By above tandem, when the report cycle of the measurement that RRM algorithm needs is constant, signaling message number and Packet Forwarding Rate on IUB mouth link significantly can be reduced.RNC side joint oralia and signal command board CPU usage is reduced while guarantee RRM algorithm promptness.

Two, the general but measurement report requiring MR and CDL of intensive collection to need of ageing requirement adopt NODEB to generate mode that MR file employing File Transfer Protocol uploads to RNC is carried out

FTP link is set up for obtaining configuration file when starting with RNC in ATM or IP transmission mode base station, and NODEB therefore can be taked to transmit MR file this type of metrical information of mode process to RNC by FTP.When obtaining IP address in base station initiated process, the corresponding IP address pool numbering in base station is got from RNC, when the measurement of MR needs is carried out in base station, MR file is generated and compressed file by the form of RNC notice, picker's information is comprised in MR file, time, the information such as data of individual count device index in this cycle.When the time of transmitting MR file arrives, set up FTP with RNC and connect, upload MR file to RNC.There is quantitative restriction in the link provided due to RNC side ftp server, such as, the restriction of (SuSE) Linux OS acquiescence is generally 256.Therefore upload in the practical application of ftp file at NODEB, the number of base stations simultaneously uploaded must be managed.The FTP number of links set up when reporting MR file in multiple base station is made to be no more than the linking number of operating system restriction, namely synchronization is no more than the linking number of operating system system restriction or the number of links of RNC restriction to the base station number that ftp server request SOCKET connects, the FTP needing RNC to control to set up to be connected within the scope of system safety and to ensure having equal opportunities of all base station schedulings, and can the FTP linking number simultaneously set up of dynamic conditioning as required.

Control strategy is as follows: RNC according to configurating base station number and the maximum FTP linking number that simultaneously can set up, calculate set up FTP connect base station batch.RNC according to the difference of IP address of distributing base station, by batch being divided into different IP address pool numberings.By the dhcp process of IPOA process and base station self-starting, notice NODEB address pool numbering.Base station is numbered according to address pool, sets up FTP and connects, upload and measure MR file by the SFN moment point that the circulation of address pool numbering is corresponding.Take this strategy that the multiple NODEB concurrent FTP of foundation connection simultaneously can be avoided to cause FTP to set up and unsuccessfully cause files passe failure problem.

Define all NODEB to set up FTP and connect that to upload the MR file time be once the repetition period, it is that MR file reports repeat length that the FTP of every batch of NODEB continues maximum duration, and every batch of NODEB sets up FTP, and to connect the moment be that MR file reports skew.

Definition base station address pond Serial Number Range: [1, N], N is base station address pond number.

The repeat length that base station upload file in each address pool continues is the complete cycle of K SFN, and the complete cycle of 1 SFN continues duration [0,4095] individual 10ms size.The link bandwidth that K can provide according to the size and FTP uploading MR file determines.For ensureing in same address pool that different base station Startup time is different, the complete cycle of K SFN comprises protects interval, transmission delay when computationally reporting the cycle for compatible base station and RNC.

Define in each repeat length and can set up FTP to connect the number of base stations uploading MR file be M, lower than the maximum FTP linking number that RNC can be concurrent.

FTP is set up in definition address pool base station, and to connect the skew of uploading MR file be offset, offset scope: [0, (N-1) * K], namely address pool is numbered the base station of 1 is the file transmitted in 0 to K in one-period at SFN, the base station that address pool is numbered 2 is the file transmitted in K to 2K in one-period at SFN, the like.All base stations report the repetition period to be once: N*K.

Therefore, address realm is belonged to the base station of address pool numbering n, sets up FTP and to connect and the time point of uploading MR file is:

SFN _i＝((N*K*(i-1)+(n-1)*K))mod(N*K)

Duration is i-th time, the base station transmission MR file that K, i represent address pool numbering n.

RNC safeguards the MR upload file repetition period, when base station initiated, the skew repeating skew and repeat length of informing base station current repetition period, NODEB starts to calculate MR according to home address pond numbering and the current skew repeating skew and repeat length and reports moment point.Base station is when generating MR file, MR file can be compressed and improve efficiency of transmission further, and name uploads to RNC particular category, the form that file format takes MR server to need on request, avoid RNC again to regenerate MR file by MR server requirement form and improve treatment effeciency.File format, name and file size and upload the information such as path and obtain from RNC in base station initiated process.

RNC can report MR file size to assess the busy program of each base station according to according to base station in many repetition periods, and dynamic conditioning busy base station IP address attribution address pool does equilibrium.Also can according to busy degree, dynamic conditioning address pool size, the repetition period of adjustment upload file, avoids there is the concurrent upload file in multiple base station at same shift time point, makes the load-balancing performance of system better.Changed by the address change of OM channel informing base station and repetition period, base station after this transmission cycle terminates, can be adjusted to the new cycle and uploads MR file.

Introduction based on above-mentioned specific embodiment can be found out, the present invention needs trigger source and the application target of measurement according to RNC, carries out the classification of measurement information reporting method.Message tandem periodic report on NCP and CCP link is taked in the measurement that RRM algorithm needs, and concatenateable message utilizes the ASN.1 of the automatic compatible NBAP_PDU of the reserved field of NBAP agreement to encode, without the need to revising agreement.Ftp file mode periodic report is taked in the measurement that MR needs, and supports ATM and IP multi-mode base station, and MR file format code requirement requires to gather form, makes full use of RNC side and has FTP SERVER function, does not need to add additional hardware resources.

For reaching above technical purpose, the invention allows for a kind of base station equipment, as shown in Figure 3, comprising:

Acquisition module 310, for obtaining type and the measurement demand of measurement, described measurement demand comprises: need to open RRM algorithm, need to open MR and need to open CDL;
