1.1 Basic Process Introduction

Network optimizing is a significant point during the wireless network constructing, the function of

wireless network always varies while the network is developing, subscriber amount is increasing and

subscriber distribution altered. Therefore, network optimization is to guarantee the network function will

satisfy the subscribers all the time.

The complete flow of wireless network optimization is shown as figure 1.The unnecessary stages in

this flow will be cancelled according to the client




Figure 1 Network Optimizing Flow

The wireless propogation environment should be ensured firlstly in the process of network optimizing,

and then the problems in the network should be solved step by step form part to entire (from single BS to

cluster then to whole network).

The functions of main stages in network optimization are as below:

1. Requirements analysis: to understand the working target and obtain useful information.

2. Spectrum scanning: to ensure the wireless environment (without interference).

3. Sample station inspection: to ensure a single station works well.

4. BS cluster optimization: to ensure a part of network area works well.

5. Entire network optimization: to ensure the whole network works well.

A network optimizing project may adopt the organization structure as a network programming project,

which is shown as figure 2.




Figure 2 Structure of Network Optimizing Project




1.2 Requirement Analysis

The purpose of requirement analysis is to obtain the detail requirement of a project, including the

client




1.3 Spectrum Scan

1.3.1 Scanning overview

Spectrum scanning is to know whether the interference exists in the system spectrum, including

scanning and interference checking. Generally, the scanning is needed; the interference checking should be

implemented by the company which has the relevant intelligence. Spectrum scanning is conducted for

confirming whether there existing interference within the working frequency band and selects proper

channel number with no or little interference for the current network. In the WiMAX system, the TDD

mode is adopted by the network, so scanning either uplink or downlink is enough.

1.3.2 Scanning test type and test tools

1.3.2.1 Test type

The spectrum scanning can be classified into two types: drive test and fixed location test. The

drive test can find possible areas with interference but it cannot identify the accurate locations of

interference sources. While the spectrum scanning at fixed locations can search out more detailed

information about interfering frequencies, such as their direction and position, strength, etc. Select

the test type depending on the actual situation; referring to the Regulations of Frequency Scanning.

1.3.2.2 Test tools

1. Spectrum Analyzer

2. Omni antenna type and antenna gain

3. Filter loss

4. LNA gain

5. Proper RF cable (confirm cable loss)

6. GPS receiver

7. PCMCIA card (or Flash memory/Serial cable/Floppy disk)

8. Laptop

1.3.2.3 Spectrum analyzer parameters setting

1. Central frequency

area as much as possible.

2. Connect the test devices; set the resolution band width (RBW) as 10 kHz; the band width is

XX MHz~XX MHz.

3. Conduct the DT on the designated routes, recording the variation information of the signal

when passing on different paths.

4. Analyze the test data.

1.3.3.2 Fixed location test procedure

1. Select the test points;

2. Locate with the GPS, recording the longitude and latitude of test points;

3. Connect the test devices, and set the test software properly;

4. Without antenna connection, measure noise floor of the spectrum analyzer. Note that the RBW

setting during this step should be accorded with that used in the actual frequency scanning process.

If the noise floor is normal, go on to the next steps; otherwise, check out whether the spectrum

analyzer can work properly.

5. Connect antenna, filter, etc., and measure the noise floor of target frequency band, then save

1. Distribution figure of positions with interference: mark the positions where there exists

interference in the figure and make a serial number for each position.




2. Figure of signals received in positions where there exists interference: provide the frequency

spectrum figure featuring the interfering signal. For each position, present a corresponding

1.3.5 Analysis of interference in service areas

According to the test result of DT, present the areas with relatively strong interference and describe the

interference details;

According to the test result of the point test, supply the information of the sites with relatively serious

interference;

Present the information of the frequency bands within which there is relatively much interference;

Present the primary analysis about the interfering signals (for example, showing whether the

interference signal is regular or not), along with the rough range of the interference intensity (power).

According to the result of frequency scanning, we can get the following conclusions:

1.3.5.1 The influence of external interference

If interference exists in radio system, it can influence all performance and the most important

influence is coverage radius (reverse coverage radius especially).

Since WIMAX is a spread spectrum communications system, the low power and narrow

bandwidth interference only influence less WIMAX system, but the high power and wide

bandwidth interference can interference seriously WIMAX system. There is an example to

calculate the influence.

An interference calculation example is given in 2500MHz WIMAX system, because there are

some PTT systems, radio access system and many illegal users, these high power and wide

bandwidth interference will influence seriously the 2500MHz WIMAX system if it is set up.

If the interference with 20KHz bandwidth and average

When finished the scanning test, we need to make conclusions and export scanning report. The

report format can refer to < WiMAX spectrum scanning report template>.

1.3.6 System OMC uplink spectrum scanning instruction

1.3.6.1 Overview

The guide book is writed for WiMAX wireless network optimization. The WiMAX technology

has initially with my colleagues in the background, you can directly refer to the instructions of the

work flow and processing methods.

The guide book is writed for the guidance of WiMAX wireless interference investigation work

environment.

The main method is to clear away the use of system functions to locate and troubleshoot

interference. It supports the functions of the above version 3.20.02B1 version.

1.3.6.2 Uplink spectrum scanning function

1.1 Introduction

Uplink spectrum scanning includes two functional modules, the spectrum scanning and

analysis of base-band interference.

1.1.1 Spectrum Scan

Spectrum scanning function is defined as a prerequisite for access to non-users, in the specified

uplink Segment (also designated carrier) on the specified antenna configuration of the entire

channel bandwidth for the sub-carrier power (average power or peak power) scan, and reported the

results of scanning to the background, which can be configured in the background shows the whole

bandwidth of the spectrum (the power of all subcarriers), channel bandwidth and PAPR RSSI,

similar to the function of spectrum analyzer.

1.1.2 Analysis of base-band interference

For broadband interference, RSSI can be observed in general to judge, therefore, interfere with

the analysis of base-band narrowband interference only. Through the analysis of base-band

frequency spectrum characteristics of each symbol in order to determine whether there is

interference. If there is interference, will be the peak position (interference location) average

(subcarriers), and peak position of the variance, more than the ratio threshold, such as the specific

results reported to the background.

1.2 The purposes and the basic principles of base-band interference analysis

1.2.1The purpose of base-band interference analysis




The received signals of WiMAX system, beside we need the terminal signal, may also include

other source signals, the source of the signal system where if falls on WiMAX channel bandwidth,

and up to a certain intensity, the interference has become. WiMAX systems will interfere with a

certain degree of performance degradation, such as access would cause some users uploading and

downloading speeds drop, performance instability. Serious interference will lead terminal unable to

access network and so on. Analysis of base-band interference is in accordance with the purpose of

setting the parameters of the background base-band sampling and analysis, from the surface to

determine whether there is interference. If there is interference, it will interfere with the analysis of

the results (such as the interference location) reported to the background, so that we can know

which band is the existence of interference in the band WiMAX system settings, you can

circumvent the interference of these frequencies, to improve the WiMAX system performance.

1.2.2 The principle of base-band interference analysis

According to base-band received frequency domain data for each sub-carrier power calculation,

and through 22 sub-carrier power comparison between the subcarriers from the largest power, as

peak power, and then divided by the peak power of all other sub-carrier average power , the PAPR.

The use of PAPR calculated with the background set the threshold for comparison, if the reporting

period exceeds the threshold PAPR specific ratio of the proportion of the background set to

illustrate the existence of interference, the results will be reported to the background interference.

1.3 Use instructions

1.3.1 Start conditions

After the success of start, if there is interference (ie, memory cycles calculated in the base-band

sub-carrier average power ratio PAPR PAPR set the background threshold high, and the proportion above

the threshold set to meet or exceed the proportion of the background), will be the peak position

(interference location) average (subcarriers), and peak position of the variance, more than the ratio

threshold, such as the specific results reported to the background. If every report period returns a

message, in the spectrum scanning interface will add a record, as shown in Figure 12.




Figure 12 Base-band interference analysis reported result

Reported the results of three major parameters:

1. The peak location (the location of interference) average / Interference Location Average, 2. That is

the figure reported to the sub-carrier, 3. From No. subcarriers can be provided in accordance with the

method followed to calculate the frequency bands where interference.

4. Peak location variance / Interference Location Variance, 5. This parameter can be compared to

determine whether interference with a fixed location in the same 6. The peak position of the variance is

zero, at one place, as the Figure peak location variance is zero of 512. 7. That interference in the 512

fixed on the sub-carrier. The deviation value is more small, 8. Interference occurred in the more fixed

position, 9. Contrarily. 10. The location of interference 11 not more fixed.

12. More than the specific ratio of the threshold / Over Threshold Ration, 13. The main report shows

that in a cycle, 14. PAPR exceeds a set threshold ratio.

If there is no interference, then there will be no background in data reporting. The definition of

interference is related to the setting threshold of PAPR and the proportion of the over threshold value.

Notes: 1. Background PAPR threshold set to 0 when data should be reported, but there is not

interference.

2. Detection of interference, the need to constantly adjust the settings background PAPR threshold, so

that the peak position reported to minimize the variance (preferably 0), this report should be the peak

position is relatively fixed to the existence of interference the location of the. Bandwidth on the 10M and

7M, the peak position of 512, corresponding to its center frequency; 5M bandwidth for the peak position




of 256, corresponding to its center frequency. 10M, 5M width of each sub-carrier is about 10K, 7M about

7K, it can interfere with the location value, center frequency, the width of each subcarrier to calculate

about the existence of band interference, this can also scan curves with the spectrum to see.

3. To detect the existence of band interference can be by modifying the system to the center frequency

band to avoid interference.

1.5 Calibration Test

Adjustment test is used for testing the loss in different environment, so that the coverage of other

environment can be calculated according to the data of the environment that has been tested.

Adjustment test consists of items below during network optimizing:

1. Indoor penetrating loss testing

i. This process is to test the loss between Indoor and outdoor, in order to know the Indoor coverage

situation according to the drive test.

ii. Through the concurrent test of two terminals Indoor and outdoor, the Indoor penetrating loss

can be obtained according to the receiving power of the weo terminals.

2. Vehicle antenna adjustment test

i. This process is to test the loss of vehicle antenna; it is used for the tools which need vehicle

antenna. The test result of inside vehicle can be deduced according to the vehicle antenna testing.

ii. Put the antenna of testing tool inside or on the top of the vehicle, according to the signal

strength, the gain between vehicle antenna and inside can be obtained.

3. MS antenna test

i. This process is to test the signal difference between the MS antenna and inside vehicle, the

inside coverage effect can be deduced according to the testing data of MS antenna.

ii. Connect the MS antenna with the vehicle top and test the receiving power, compare with the

receiving power of inside vehicle, the antenna gain in normal situation can be obtained.

4. Test of average penetrating loss in vehicle

i. Test the signal difference between inside and outside vehicle, calculate the outside

1.6 Network Evaluation before Optimization

Before optimization, to estimate the situation of network has effect in two aspects: 1. to compare with the

network after optimization and know the optimizing effect; 2. to find out the problem in current network,

this will be the guidance for network optimization in future.

Tasks in this stage:

The flow of network estimation is show as figure 13.

Figure 13 Brief Flow for Network Evaluation

Tasks in this stage include:

1. Confirm whether OMC data can be provided, transitted network needs to be coordinated;

confirm whether the data estimation is needed.

2. Define the parameters which are confirmed by the contract and client. If no requirement is in

the contract, the parameters should be defined as universal values or sub-branch company




confirmed; the parameters include test path of DT(drive test), test point of CQT(call qualty test),

test time, calling method; and confirm the test method for data operation, such as FTP or Iperf.

3. Confirm the estimating project and standard, if this is not provided, it should be given by

client; if client can not do this, and general standard should be involved for estimation.

4. Make a plan: including the requirement of time, staff and resource. Time should be

confirmed by client, DTぎCQT and OMC can be operated in parallel or serial according to

the requirement of resource and time.

5. Data collection: DT test, CQT test, and OMC data collection should be operated according

to predefined parameters:

i. DT test consists of urban DT and main roads DT, record datas DL received, such as RSSI,

CINR, inverse emission power, connection times, successful connection times, lost

connection times, DL/UL data rate, handoff times, handoff delay, etc.

ii. CQT test is operated in dense urban area only, which is to test voice and data. Record datas

DL received, such as RSSI, CINR, inverse emission power, connection times, successful

connection times;

iii. OMC target is the entire network data, which generally includes successful calling rate, lost

rate, and adjust according to the client




1.7 BS Cluster Optimization

The purpose of BS cluster optimization is to locate in sections and solve problems in the network, which

may have peoblems in network estimation, cluster testing and others. Frequent problems are: low quality

voice, high lost rate, and calling difficulty, low data rate, calling failure, long setup time and low successful

handoff rate.

Tasks of BS cluster optimization are introduced as below:

For a large network, especially an unfinished projest, or malfunction BS is in a network, it is necessary to

divide the whole network into small clusters, and optimize one by one. This method decreases the difficulty

of optimization, which is named as cluster optimization.

BS cluster optimization includes tasks below:

1. BS cluster division

i The entire network should be divided into clusters before optimization, generally less than

19 BTS (BS amount in standard network topology), overlap should exist between

contiguous BSs.

ii BS cluster is marked by the standards below: topography business requirement. The areas

have particularly needs in data or voice should be marked in the same cluster, so problems

can be solved easier. The areas which have same problems in networks should be marked in

the same cluster.

2. BS cluster optimization:

i BS clusters can be optimized in serial or parallel according to the resource siyuation and

time requirement.

ii Solve problems in different topics: such as coverage, business, handoff, etc.

iii Base on the information about problems of network estimation and cluster test, engineers

analyze the problems and make the solution.

iv After the adjustment is implemented (including the site adjustment and parameter

adjustment), engineers should test the area where problems exist; if problems have been

solved, go to next stage, otherwise it should be analyzed again.

v After all problems have been solved, engineers should test the entire BS cluster and collect

information of acceptance checking; it meets the acceptance, go to optimize the next cluster,

otherwise the affecting elements should be analyzed and optimize furthermore.

vi After every BS cluster meets the standard of acceptance checking, go to optimize the entire

network.




1.8 Whole Network Optimization and Network Evaluation

After all BS clusters have been optimized, the entire network needs optimizing to solve the problem

between BS clusters. When the retire network meets the requirement, the network function can be known

by estimation.

Tasks in this stage:

After all BS clusters optimization has been finished, systems in most areas should work well, but in some

area, especially the clusters overlapped area, problems might exist. These parts should be adjusted

considering function guide to achieve the final target of network optimization. The working flow is as

below:

1. Understand the optimizing purpose which is the target should be achieved.

2. Confirm the testing route, including all important coverage area.

3. All around driving test.

4. Analyze testing data, find out problems in the network and make an adjusting scheme.

5. Implement the scheme and test to verify.

6. Analyze the testing data, comfirm whether it achieves the prospective target. If it achieves,

go to next problem, otherwise optimize further.

7. If all problems have been solved, go to the network estimation after optimization, test the

optimized area according to the acceptance checking standard.




1.9 Project Acceptance Test and Report Hand in

Project acceptance checking is to test the project according to the contract or agreement. The inspecting

standard is in the contract or agreement. Tasks in this stage include items as below:

1. Make a plan, start testing after the person who is charge of this confirms.

2. Determine the testing route and set the parameters according to the contract or agreement; if no

regulation is in the contract, we should consult with client; the CQT test is probably needed based

on the contract.

3. Test and record the data in background, write <checking testing report> according to the data; if the

nerwork meets the standard, write <wireless network optimizing report>; if the network not meets

the standard, check after analyzing and solving problems; client

computer.

ii. Click the right mouse button, pop-up shortcut menu, click on [Auto Detect All].

iii. At this time the name of the port in the back, will show the current state of testing. If the

equipment successfully detected, the port will automatically mount the following device name. If

testing fails, what ports do not show the back (when the detection fails, the users need to refer to




equipment manuals, carefully testing equipment, as well as the connecting device parameter

settings).

4. Intelligent Detection: ZXPOS CNT1 will check and test equipment by previous hardware

configuration, if the device is detected the same with last time, it will enter automatically the Live

Testing mode. When the equipment and their connection mode are fixed, it is the fastest check and

test mode.

Flexibility uses the three testing methods that can enhance the work efficiency.

2.3 RF Optimizing Subject

2.3.1 RF Optimizing Goal

RF optimization goal is making the cover signal be optimization, considering the balance of the uplink

and downlink broadcast path, the test parameter of cover optimization primary is DL RSSI and DL CINR.

Do optimization can through modulate antenna and transmit power.

RSSI this parameter is the most important index for test covering, through the transmit power we can

work out actual link loss. RSSI is the important reference for regulate rated power. Because of the

segment




2.4 Access and Paging

In order to optimize net, it is mandatory to know the basic net connection and page procedure, the

rough introduction is below.

2.4.1 Basic connection flow

2.4.1.1 Connection flow chart

Figure 57 Connection flow chart

2.4.1.2 Small area option and downlink synchronization

At the initial phase or after signal lost, the terminal will get the downlink signal channel. If the

terminal stores the last operational parameter, then it should try to regain the recorded downlink

signal channel firstly. If failed, then it starts to scan the possible downlink signal channel

continuously within downlink until it finds an effective downlink signal. As long as physicalal level

gets synchronization (), MAC level manages to get the control parameter of downlink signal

channel and then the control parameter of uplink signal channel.

The downlink physicalal synchronization for WiMAX system depends on Preamble.




MAC level will search for DL-MAP MAC management information. As long as terminal receives

at least one DL-MAP information, it will get MAC synchronization.

After downlink synchronization, the terminal waits for UCD information from base station, in

order to get the parameter group from uplink signal channel.

Main information: DCD and UCD

Open loop is mainly carried out by MS. By calculating path loss and modulation coding modules,

interference of BS, MS adjusts Tx power properly. The advantage of open loop is higher adjusting

frequency, lower delay, no need bandwidth spending, because of no close loop, the adjustment maybe

not accurate.

Downlink PC: when MS migrates to the edge of cells, path loss increases rapidly, the quality of

signal channel turns worse, if increasing the downlink Power, you can improve communication

quality. Otherwise when MS is next to BS, the quality of channel is very good, so in the precondition

of keeping bandwidth, we can decrease power properly, decrease interference level, also save Tx

power for remote subscribers. WiMAX carries out downlink power control by adjusting Booting

value.

2.6.1.4 AMC

WiMAX adopts AMC technology, according the intension of sinals, automatic adjust modulation

and coding modes, so it

Uplink AMC and PC methods

First, confirm UIUC, according to current UIUC and CINRrcv, judge whether current CINRrcv is

in min entry threshold or mand exit threshold of current UIUC.

If so, keep UIUC, otherwise reconfirm UIUC and judge power by congestion.

Downlink AMC and PC methods:

First confirm boosting and then confirm DIUC according to CINR, the adjusting method of DIUC

is similar to UIUC.

2.6.2 Power Control and AMC configure

PC parameters are mainly: DL Burst Profile, UL Burst Profile, AMC and PC.

DL Burst Profile

In Figure 74, DL Burst Profile expresses the configurations of downlink burst modulation and

coding, this configure is the MC type used to divide downlink burst to terminals by LDS. At most

12 items, be corresponding to DIUC1~DIUC12.

Mand exit threshold and Min entry threshold are the same as uplink, the choice of DIUC is

decided by the downlink AMC method when downlink AMC enable.

The step of threshold value is 0.5db, and the step of backgroup NPT demonstrate is 1db, so you

need to use the threshold value divide 2 and then be corresponding to DL CINR of NPT. When

compare the threshold with the DL CINR of NPT, you need to notice: when downlink AMC enable,

check the mand exit threshold and min entry threshold of this DIUC, if it

UL Burst Profile

In Figure 75 UL Burst Profile is the configure of uplink burst MC, which is mainly used to assign

MC of uplink burst by LDS, at most 10 items, from UIUCUIUC9.

Mand exit threshold: uplink AMC enable, when UL CINR is lower than the value of Mand exit

threshold, system will choose a lower step MC according to uplink AMC method.




Min entry threshold: uplink AMC enable, when UL CINR is higher than the value of Min enry

threshold, system will choose this MC type, if still higher than higher stup MC, system will choose

higher MC according to uplink AMC method.

Up to now, the configure is CC and CTC, the threshold is stepped by 0.25db, but NPT is stepped

by 1db, so you need to use the threshold divide 4 and then be relative to UL CINR of NPT. When

compare the threshold with the UL CINR of NPT, you need to notice: when uplink AMC enable,

check the mand exit threshold and min entry threshold of this UIUC, if it

adjustable mechanism to prevent improper threshold of AMC making AMC performance falling.

The principle adjusting the threshold of AMC according Burst error ratio. The threshold of AMC is

to high when the error ratio is much hign, you need to reduce porperly; the threshold need to be

increased when the burst error ratio is too low.

This parameter is used to control the period of statistic of burst error ratio.

2.6.2.8 PC parameters explanation

1. DL power control enable

In the following figure 90, if DL power control enable choose Enable,it means enable downlink

PC.

Figure 90 DL PC enables

When it chooses Disable, it means downlink PC is disable. At this time, DL PC uses the gain

which fits the appointed boosting, the appointed boosting is configured to Appoint to DL boosting

as the following figure 91.

It can be choosed as 0~7which is corresponding to 0 dB (default),6 dB,-6 dB,9 dB,3 dB,-3 dB,-9

dB,-12 dB. The corresponding gain of boosting is configured in DL gain of plus value in Figure

4-50.when downlink PC enables, the value of boosting is decided by the D-value between the min

entry threshold of the highest multiplicity configured in DL Burst Profile plus 2db and the value of

DL CINR reported by FFB or REP-RSP. This D-value will be compared to boostiong values of 7,

and then confirm the boosting value. Then compare the boosting to the Upper bound of DL




boosting and Lower bound of DL boosting in figure 92 , if it




UL power controls enable

The following figure 93, UL power control enable chooses Enable, enable uplink PC, and

otherwise disable uplink PC.

Figure 93 UL PC enables

UL PC is adjusted according to the third paramter PCC reference in UL burst profile, when the

measured CINR of data burst aveage is higher than PCCI, then the UL signal quality can meet

communication, you can reduce power properly; if UL CINR is lower than the reference value, the

UL signal qualtiy can not meet communication, you need to upgrade power. The method of

average:in figure 94, average method for UL CINR measurements=0 means Alpha average,1

means slipped windows average; Alpha averagenew CINR=Alpha * reported CINR+1- Alpha

* old average CINR Alpha is configured in Alpha for UL CINR average in figure 95,ennerally

configured 1/16~15/16; windows average is slipped windows average, the size of windows if

configured in Window for UL CINR average in figure 95, the scope of upgrade or reduce is

decided by warp of CINR, in figure 94big warp chooses big step, small warp choosed small step,

Differences between close loop PC and open loop PC:

Close loop is BS measure the CINR, RSSI of data sent by MS, then compare to the target value,

confirm the power adjusting. At present, our system supports adjust according to UL CINR, in

future considering RSSI;

Open loop is mainly completed by MS. MS confirms Tx power according to the path loss, MC, the

interfere of BS. The advantage of this type is high adjusting frequency, small time delay, no extra

bandwidth; disadvantage is no close loop, the adjusting maybe not exact.

In future our system will be added external PC: BS calculates the uplink BER or PER, by

comparing to the threshold, adjust CINR dynamically to ensure the communication quality.

2.7 Admission and congestion control

2.7.1 QOS of the air-interface resource of WiMAX

2.7.1.1 Air-interface resource

The air-interface resource of WiMAX is calculated unitely as SLOT number.

By physicalal structure, one air-interface SLOT is composed of a special time length lasted by

several sub-carriers. LDS also use SLOT as operation unit, translate MAC message to PHY layer.

If the time length of an air-interface physicalal FRAME is T, the usable number of subcarriers is N,

a SLOT lasts t is composed of n subcarriers, so the total SLOT of air-interface is (T/t)*(N/n). Most

of these SLOT is used to transport service data, little part is used to control channel (DL_MAP,

UL_MAP, UCD, DCD and so on).

2.7.1.2 Flux of subscribers☂ service-flow

The air-interface bandwidth occupied by subscribers




The character of UGS is fixed service flow bandwidth, once access, the air-interface will hold

fixed SLOT for the service all the time, no matter whether there




2.7.1.4 Admission and congestion control

Admission and congestion control is two important part of QOS system, the together object of

them is to avoid overload of air-interface, ensure the quality of service flow transport.

The function of WIMAX admission control is to restrict the acess ot subscribers




The subscribers want to add or reduce the bandwidth of an accessed service flow. Thereinto, the

apply of adding bandwidth is restricted by admission control, admission control judges it by uplink

or downlink service flow.

HO of terminals

When terminals handover to other BS, all the accessed services in serving BS will be applied to

target BS.

In this scene, all the service flow of terminals should be admitted to the target BS, the HO can

be completed, or any service flow is not admitted, BS will refuse the HO of terminals.

2.7.2.4 Serveral terms considering by admission control

1. MAC overhead

SPS requests to DBS for service admission, the filled parameters of bandwidth is the payload of

Service flow, not including MAC overhead; when DBS judges by SLOT, it needs to add suitable

requirement, and then judge.

2. Reserved air-interface abundant quantity

The object of reserved air-interface abundant quantity is to have spare resource when MC types

Changed or the bandwidth of service flow alters, not as far as the property of service flow changed,

the air-interface is overload.

3. the priority of admission for different scenes

The priority of admission is that different scenes have different admission results when the

resource of spare SLOT is very tense. Among the three before-mentioned scenes, the priority from

high to low is HO, bandwidth variation and original access.

The priority is realized by reserving each air-interface resource abundance, higer priority, less

reserved abundance.

4. Disposal to different service flow

To UGS, judge by the SLOT calculated by fixed bandwidth and MC of terminals.

To VR services (ERT-VR, RT-VR, NRT-VR), judged by the SLOT calculated by the minimal

reserved bandwidth and MC of terminals.

To BE, no reserved bandwidth, so no reserved SLOT, admitted unconditionally.

2.7.3 Congestion control

2.7.3.1 Basic principle

The main reason to congestion is too much data folw, LDS cann




LDS: it answers for the Statistic of air-interface slot in time, mainly includes whether produce

attemper violation, and the rate of violation, also report to DBS cycly.

DBS: it takes charge of two jobs: first, according to the report of SLOT attemper sent by LDS,

judge whether the air-interface is in congestion, and the degree of congestion, and then sends the

report to SPS; second, when it needs to upgrade power, forcible handover or release forcibly to exit

congestion, choose the service flow and terminals according the information, and then send the

report to SPS.

SPS: SPS is the main part of congestion control, after receiving DBS congestion control report,

chooses the method of relieving congestion, and then choose the object to execute, at last relieve

congestion to the choosed object.

2.7.3.3 The scene of congestion control

According to the procreant situation of congestion, congestions are divided into no congestion,

light congestion, middle congestion, high congestion.

No congestion

No congestion: there is no air-interface slot resoutce overload, normal LDS attemper.

Light congestion

When the LDS attemper interval for BE is more than the threshold, the air-interface enters light

Meaning: including the same frequency and different frequency handover of inter_BS, handover

of intra_BS, it is difference between the inter_BS and intra_BS for handover process. The higher

the index, the probability of dropped calls for mobile users to the smaller, and it is an important

index to measure the mobile ability of wireless systems.




Formula: Hard Handover Success Rate = Hard Handover Success num * 100 / (Hard Handover

Success num + Hard Handover Fail num)

3. Average Interrupted Time Latency of Hard Handover

Name: Average interrupt latency of Hard Handover

Meaning: the duration of call interruption time when MS make handover, the index may affect the

provision of service continuity capabilities, and it is an important index to measure the mobile

ability of wireless systems, the smaller the index value, the user's experience not more obvious

when the handover occur.

4.1.2.2.5 Delay

Name: Delay for UGS Ping Service

Meaning: This index through ping packets to measure end-to-end delay of UGS service, the ping

packet bytes corresponding with the length of commonly UGS service, package used long. It is an




important index to measure the ability of system ensures UGS service. The smaller the value

means that the delay of system transfer UGS packe is shorter.

Calculation formula: Through the ping command to obtain delay, and then make the average of N

times the delays.

Statistical methods: In the terminal-side or server-side through the ping command.

Units: ms

Peer-to-peer KPI: similar indexs include ErtPS, rtPS, nrtPS and BE services ping packet delay,

and measure respectively the levels of several services delay. The following table is the simulated

packet length for all kinds of services type ping packets.

4.1.2.2.6 Jitter

Name: Jitter for UGS Ping Service

Meaning: Jitter indicate that from the terminal sent a UGS service packet to the core network has

been received (or sent from the core network to the terminal has been received) changes in the

value of the delay.

This is an important index to measure the ability of system ensures UGS service. The smaller the

value means that system transimit more stable for UGS packets.

Formula: jitter = Delay (max)-Delay (all_packet_in_stream)

Statistical methods: Through ping command to get delay at the terminal side or core network side,

and then calculated jitter according to the formula.

Units: ms




Peer-to-peer KPI: similar indexs include ErtPS, rtPS, nrtPS and BE services ping packet jitter, and

measure respectively the levels of several services jitter.

4.1.2.2.7 Packet Loss

Name: Packet loss for UGS Service

Meaning: This index defines the proportion of lost packets with the total transmission packets of

the IP layer. This is an important index to measure the ability of system ensure UGS service. The

smaller the value means that the correction ability of system transimission is stronger for UGS

service packets.

Formula: packet loss = 100 * Number-of-lost-packets/Total-number-of-sent-packets

Statistical methods: Use Iperf tool transmit the corresponding with UGS service the same length

packets to abttain this index value at terminal side or core network server.

Unit: %

Peer-to-peer KPI: similar indexs include ErtPS, rtPS, nrtPS and BE services packet loss rate, and

measure respectively the levels of several services packet loss.
