2 Overview
2.1 Function Introduction
2.1.1 System Data Acquisition
ZTE RAN equipment supports the collection of the following system data:
Performance statistics
ZTE RAN equipment collects various records generated during whole -network
users' call and service process. According to these records, we may customize
from an OMCR the output reports which include the following KPIs:
RRC establishment success rate and RAB establishment success rate
Call blocking rate and call drop rate of CS/PS
Soft handover success ratio, hard handover success ratio, and Inter-RAT
handover success ratio
Throughput and bandwidth utilization ratio of Iu/Iub/Iur interface

Traffic and flow of RNC/cell
Cell load level, utilization ratio of code resource
E1/IMA link performance statistics, AAL5/AAL2 performance statistics
IP performance statistics of Ethernet port, etc.
Signaling message
Collect the signaling messages generated when specified users make calls,
support the signaling tracing tool of an OMCR, trace specific users' messages to
observe their call process and status, and facilitate the analysis and location of call
drop.
Online analysis of Radio Performance
Collect real-time Radio Performance during user call, including transmission power
and quality of radio links, transmission power of a cell, and uplink interference. The
graphic interfaces provided by an OMCR, such as curve diagrams and forms, make
it more convenient for users to analyze and browse..
2.1.2 Neighboring Cell Monitoring
Defining a neighboring cell relationship correctly is of vital importance to maintain
superior mobility of UE and to avoid unnecessary interference. Too many or too fewneighboring cells, or a wrong neighboring cell relationship will result in severe call drop.
The neighboring relationship between cells in a network is always defined at the network
planning stage. But actual network construction and radio environment may make actual
cell coverage inconsistent with simulated network planning. As a result, the Radio
Performance ( for example, adjacent cell ) configured according to network planning, may
not be reasonable. Thus, the network handover success ratio is reduced and the call
drop ratio is increased.
ZTE RAN equipment supports the following modes of neighboring cell monitoring:
The neighboring cells that misses configuring.
By controlling detected set measurement of UE, the RNC can find that a cell fails to
be configured as a co-frequency neighboring cell, but actually there exists
overlapped coverage.
The excessive neighboring cells that is configured.
By checking the handover times and success ratio of UE between cells, the RNC
can find that a cell is configured as a co-frequency neighboring cell at the
background, but actually there does not exist any overlapped coverage.

The neighoring cells with specific handover priority
By checking the handover success ratio of UE between neighboring cells, the RNC
can recommend configuring the handover priority for the neighboring cell of a cell. If
a neighboring cell with a high handover success ratio is configured with a high
priority, the probability of handover to this neighboring cell may be increased.
The functions provided by this feature can serve as the substitute for complex and
expensive third-party network optimization tools. Avoid inefficient but high-cost modes,
such as coverage survey and drive test, and optimize network fast and effectively.
2.1.3 Meaturement Report Record
The measurement report (MR) sent by the UE covers intra-frequency measurement,
inter-frequency measurement, inter-system measurement, service traffic measurement,quality information, UE internal measurement, and location information. This attribute
supports collection, storage, and output of detailed measurement information.
The MR based data provides local cell synchronization/measurement information, RSCP,
and Ec/N0 information, and displays the information in a geographic way. Through the
MR data, you can know the area of weak coverage or no coverage and give suggestions
of adding more base stations.
The MR based data provides inter-system cell measurement information, allowing you to
know the coverage of another system and configure adjacent cells of another system.
The MR data based statistical analysis allows you to know the RSCP and Ec/N0coverage and interference o f the overall network.
Based on the correlated measurement information of the local cell and adjacent cell and
UE transmit power, you can swiftly identify the areas with weak coverage, cross -cell
coverage, and pilot pollution, and diagnose external interference and optimize the
adjacent cells.
Therefore, based on the measurement report records (MRR) of the existing network
users and network planning & analysis tool, the system diagnoses the net work coverage
and interference in replacement of high-cost network optimization methods (such as
drive test).

3 Technical Description
3.1 System Data Collection
3.1.1 Performance Data Collection
Performance management is one main management function of a telecommunication
management network. It collects network performance data in real time, monitors some
service events in network running in real time, and stores network performance data for
a long time. This provides a basis for the assessment and trend analysis of a public land
mobile network system. Performance management is implemented by means of
performance measurement and service statistics. By working out a series of
measurement tasks, network maintenance personnel collect performance indexes fromvarious network units to implement network performance management. They also
confirm the physical and logical allocation of network, and find out any potential problem
as soon as possible.
The PM module is functionally categorized as data collection and data reporting.
1 Data collection: collect and summarize the counter values.
2 Data reporting: In each data collection granularity, data is collected and all counter
values are sent in the form of messages to an SBCX. The SBCX saves data as a
corresponding file so that an OMCR can read it.The basic architecture of the PM module is as follows:

Figure 3-1 System Architecture of Performance Statistics
The basic process of performance data collection and reporting is as follows:
When a defined event happens, the RNLC etc. invokes the interface provided by the PM
and writes count to the shared data area.
When a measurement period expires, the PM execution module sends the content in theshared data area to the measurement data buffer of the PM master control module.
To avoid any data conflict, the PM execution module switches over the data snapshot
area to the shared data area.
The PM master control module on the ROMP board summarizes the content in the
measurement data buffer, and sends it to the SBCX, which saves it as performance file s.
The OMC-R reads the performance file and warehouses the data.
3.1.2 Signaling Tracing (ST)
ST is an important function of equipment maintenance. WRNC receives an ST task f rom
an RCT or CTS. The operation and maintenance subsystem works with the radio
subsystem to report the signaling which satisfies user-specified conditions to a
corresponding c lient. The key functions of ST are as follows:
1 Task control (including creating or deleting a tracing task)
2 Data reporting (report the signaling which satisfies task conditions to a
corresponding client)

The basic architecture of ST is as follows:
Figure 3-2 System Architecture of ST
The basic process of task control is as follows:
The CTS creates a tracing task by means of an OMM forwarding subsystem or an ST
Tool.
Both the clients deliver task parameters to the ST Manager.
The ST Manager checks the parameters, for example, whether there are too many tasks.
If the parameters are suitable, the ST manager delivers task data to the ST Agent on the
RCP.
The ST Agent delivers task control parameters to an associated subsystem, which
returns a response value, indicating that task creation succeeds or fails.
In an opposite direction, the response message returns the data to a corresponding
client. The client may know whether task creation succeeds or fails.
The basic process of data reporting is as follows:
While processing a signaling, the RNLC checks whether this signaling satisfies the
filtering condition of the created task. If the signaling satisfies such conditions, the
subsystem will invoke the interface of the ST Agent to report signaling data to the ST
Manager.
The ST Manager reports the signaling to the client which creates a corresponding task.

1 UE-oriented ST, which uses an IMSI as the object and traces the signaling of UE at
the Iub, Uu, Iur, or Iu interface
2 Common ST at the Iub inter face, which uses Nodeb or a cell as the object
3 Common ST at the Iu interface, which may speci fy CS domain or PS domain
4 Multiple cell users tracing, that is, the system can trace a specified number of UE in
a specified cell. The reported signaling covers the Iub, Uu, Iur, and Iu interfaces.
The above ST is only used to trace high service protocol layer information. That is,
NBAP layer signaling is traced at the Iub interface; RANAP signaling is traced at the Iu
interface; RRC layer signaling is traced at the Uu interface; RASAP layer signaling is
traced at the Iur interface.
In addition, WRNC tracing provides service for two kinds of clients. One is RCT, whichprovides all the above tracing functions. If accessed, the Call Trace Server (CTS),
together with other NEs, can implement whole-network tracing. The CTS only supports
UE-oriented ST.
3.1.3 Online Analysis of Radio Performance
Online analysis of Radio Performance fully borrows the architecture and flow of ST. It is
different from the signaling trace system in a general sense in that in online tracing, a
radio signaling control subsystem does not report the original signaling, but necessary
data extracted from the signaling. The data displayed by the OMCR is not simple databrowse. The OMCR provides some more friendly display modes, such as curve
diagrams and forms, which makes it more convenient for users to analyze and browse.
Online tracing provides the following functions:

3.2 Neighboring Cell MonitoringNeighboring cell monitoring is an optional function. When the NbrCellMonSupInd is close,the measurement ID11 cannot be opened, so this function is also disabled.
For the sake of description, neighboring cells of UE are categorized as follows:
1 Monitored set neighboring cells: They are configured for UE by means of the
neighboring cell list of measurement control messages.
2 Non-monitored set neighboring cells: Measurement control messages can only be
configured with 32 neighboring cells at most. When an active set includes multiple
cells, there may be more than 32 neighboring cells. Non-monitored set neighboring
cells refer to those configured for an OMC-R, but not for UE due to the restriction of
air interface messages.
3 Neighboring cells which miss configuring: The neighboring cells which miss
configuring in an OMC-R.
To UE, non-monitored set neighboring cells and the neighboring cells which miss
configuring are all detected set neighboring cells. WRNC supports UE-triggered
detected set handover of measurement reports of non-monitored set neighboring cells,
and UE-triggered detected set statistics on the neighboring cells which miss configuring.
The RNC uses intra-frequency measurement ID1 for handover, including normal intra-
frequency handover and detected set handover. The neighboring cells obtained from
event reporting o f measurement ID1, which plus active set cell times is handover times.
The RNC uses intra-frequency measurement ID11 for detected set statistics. To save
intra-frequency events, measurement ID11 includes 1A events only. 1A event
parameters, such as Reporting Range Constant and Hysteresis, can be set to roughly
estimate how many times the neighboring cells which miss configuring are virtually
added to an active set. These times are called virtual handover times. Set Reporting
deactivation threshold of measurement ID11 as 6. Even if the active set is 3, 1A events
can be normally reported.
The event parameters in measurement ID1 and those in measurement ID11 can be set
respectively. It is recommended to configure the event parameters as follows in order to
make the handover times related to measurement ID1 comparable to the virtual
handover times related to measurement ID11 and to facilitate the analysis of the
neighboring cells which miss configuring the priority:

R1a(ID1)-1/2H1a(ID1) = R1a(ID11)-1/2H1a(ID11) (1)
R1b(ID1)+1/2H1b(ID1) = R1a(ID11)+1/2H1a(ID11) (2)
The event1a criterion of measurement ID1 and measurement ID11 are same based on
the formulae (1) and (2) , refer to the following figures.

According to the equations (1) and (2), we can get
H1a (ID11) = R1b(ID1) - R1a(ID1) +1/2[H1b(ID1)+H1a(ID1)]
R1a (ID11) = 1/2[R1a(ID1)+R1b(ID1)]+1/4[H1b(ID1)-H1a(ID1)]
Remarks:
1 The subscript in the brackets indicates the measurement ID;
2 R1a the parameter of "Reporting Range Constant " in Event 1A. R1b indicates the
parameter of "Reporting Range Constant" in Event 1B
3 H1a indicates the parameter of "Hysteresis" in Event 1A. H1b indicates the
parameter o f "Hysteresis" in Event 1B.
According to the above description, the trigger condition of Event 1A in measurementID11 is equivalent to Event 1A triggered in measurement ID1. In normal cases, the
threshold which triggers 1C is greater than that which triggers 1A. In measurement ID1,
if the cell which triggers a 1C event is used as the neighboring cell which fails to be
configured, it will necessarily trigger a 1A event first. Therefore, Event 1A in
measurement ID11 is comparable to Event 1A + Event 1C in measurement ID1 and is
accurately matched with Event 1A in measurement ID1. By comparing handover times
with virtual handover times, we can evaluate how important the neighboring cells which
miss configuring are to the configured neighboring cells. Meantime, we can optimize the
priority of the configured neighboring cells.

In actual applications, we first need to turn on the measurement task of detected set
monitor in the configuration interface. When UE enters CELL_DCH status, or the best
cell in UE active set changes, the RNC enables or disables the detected set
measurement o f measurement ID11 according to the status o f the detected set reporting
measurement task of the best cell. If the measurement set of measurement ID11 is
opened, the wireless control subsystem will report detected set information to the
operation and maintenance subsystem. Then, the operation and maintenance
subsystem reports the handover counter of the detected set to the OMCR, which
processes the counter value.

implementation):

2 Handover times/ virtual handover times: soft handover (including softer handover)
radio link addition attempts in the measurement object reported by WRNC + inter-
cell detected set statistics.
3 Handover times of monitored set neighboring cell: inter-cell monitored set handover
statistics of newly added counters in the measurement objects reported by WRNC.
4 Handover success ratio: soft handover (including softer handover) radio link
addition success times in the measurement object reported by WRNC/soft handover
(including softer handover) radio link addition attempts.
5 Handover ratio: It refers to the ratio of the handover times of a monitored set or non-
monitored set cell to the total handover times of all monitored set or non-monitored
set cells.
6 Distance: It is calculated according to on the latitude and longitude of neighboring
cells and source cells.
7 Neighboring cell priority: For a monitored set or non-monitored set cell, neighboring
cell priority comes from database configuration. For a detected set cell, the system
automatically generates a recommended priority during report formulation according
to the virtual handover times of the cell.
Traverse records are classified as follows:
1 Type 1: It refers to the neighboring cells configured for UE by means of an OMC-R,
including monitored set neighboring cells and non-monitored set neighboring cells.This type of neighboring cells can be handed over. Therefore, we can calculate the
handover success ratio, handover failure rate, and handover ratio by means of a
performance measurement counter. The neighboring cell priority of Type 1 is
configured by means of an OMC-R. Only this type of neighboring cells can be
handed over. Handover times of monitored set neighboring cell and monitored set
handover times are provided for this type of neighboring cells.
2 Type 2: It refers to the neighboring cells which miss configuring and the only
matched cell queried from a database according to the scrambling code reported by
WRNC. The virtual handover time of this type of neighboring cells is obtained from
detected set tracing statistics. The neighboring cell priority of Type 2 is a
recommended priority, which is automatically generated by the s ystem according to
the relative relationship between the virtual handover times and handover times.
3 Type 3: It refers to the neighboring cells which miss configuring and multiple
matched cells queried from a database according to the scrambling code reported
by WRNC. This type indicates that scrambling code is multiplexed. When reports
are generated, all matched cells will be displayed. These cells have the same
scrambling code. Detected set tracing statistics serves as the virtual handover times
of the cell (among these cells with scrambling code multiplexing) which is the
nearest to the source cell. The virtual handover times of other cells with scrambling

code multiplexing is 0, which indicates that the system makes calculations and
recommends the nearest cell to be the neighboring cell which misses configuring.
The neighboring cell priority of Type 3 is a recommended priority, which is
automatically generated by the system according to the relative relationship
between the virtual handover times and handover times.
4 Type 4: It indicates that some cells cannot be matched according to a reported
scrambling code. These cells may not belong to this network or may be interfering
signal. Cell information cannot be obtained; therefore, cell name and distance
cannot be obtained, either. We can only record their virtual handover times.

Path: View->Configuration Management->RNC NE->RNC Radio Resource
Management-> Modify Advanced Parameter->UE Intra-frequency Measurement
Configuration-> Hysteresis
Parameter Configuration
This parameter indicates the hysteresis for judging whether an event satisfies trigger
conditions. It serves to avoid the trigger status change due to very small change. This
parameter is related to the measurement quantity and the event type.
To reduce the hysteresis, you may increase the probability of reporting corresponding
events; to increase the hysteresis, you may decrease the probability of event reporting.
