1.1 Coverage rate
Performance
Indicator Name
Statistics Time Granuity Statistics Area Granuity Indicator Value
Coverage rate Cell -> Node B -> RNC -> CN
Indicator Meaning
Radio network coverage rate reflect the availability of the network. Cell coverage rate is closely related to the
capacity because UMTS cell breathes according to the capacity; More important, different service has different
rate and different coverage. Therefore, network coverage rate differentiates based on user number and service
type. This Indicator has direct impact on user take and confidence on the product.
Indicator Definition
KPI formula
FRSCPR, Ec/IoS
RSCP represents received signal code power; Ec/Io represents received pilot signal quality; RSCPR & Ec/IoS
represents whether its fulfilling, R& S are thresholds of RSCP and Ec/Io respectively. If RSCPR and Ec/IoS,
F= 1; If one or neither of the conditions is met, F= 0. Discard the exceptional value of RSCP and Ec/Io that greatly
exceed the normal range of value.
The formula means the area is covered if received signal code power and signal code quality reach the threshold.
It reflects the percentage of test spots of which F equals 1 Because coverage and coverage rate vary with different
services. Therefore, F is different based on services when computing coverage rate.
Note: coverage rate refers to area coverage rate, not marginal coverage rate which is more complicated and not
considered here.

1.2 Call Establishment Indicators
Call success rate is one of the most important indicators reflecting UMTS performance
and an indicator which the operator pays much attention to. A complete call completion
rate has several layers of meaning: paging success rate paging, RRC connection
establishment success rate and RAB assignment establishment success rate. A complete
call process goes from US receiving paging message from CN to RAB assignment,
which can also be classified into originated call and terminated call process. Signaling

Indicator Meaning
It reflects UE acceptance capability of RNC or cell. RRC connection establishment success indicates that UE
establish signal connection with the network. RRC connection establishment is categoried into two kinds: one is
service-related; the other is not related to the service (such as location update, inter-system cell reselection and
registration). The former indicates call completion rate which can be used as the basis for channel configuration
adjustment; the latter reflects system load.
Indicator Definition
RRC connection establishment success rate (service-related) is the rate of RRC establishment success number
to RRC establishment attempt number. The corresponding signals are RRC CONNECTION SETUP
COMPLETE messages received by RNC and RRC CONNECTION REQ received by RNC. This indicator shall
be recorded based on different service catagory.

Indicator Definition
When thinking of radio access success rate, we think RRC connection setup success rate and RAB assignment
success rate as a whole. Taking RRC setup request number as denominator and RAB assignment setup success
number as numerator, we use the following formula to calculate service connection rate.

1.4 Mobility Management Indicators
UMTS handoff includes softer handoff, soft handoff and hard handoff. Handoff process
involves measurement control, compress mode and handoff judgement etc, and cell
breath makes handoff even more frequent. Handoff is a important part of system
mobility management and handoff success rate is a key factor evaluating mobility
management performance of the system.
Handoff success rate is grouped into soft handoff success rate, hard handoff success
rate and inter-system handoff, which reflects handoff performance of the whole system.

Indicator Meaning
It reflects the success of RNC soft handover. Soft handover can ensure UE communication quality and improve
UE OoS. Setting of the size of soft handover area is closely related to system capacity. Users can sense the
indicators indirectly.
Indicator Definition
Soft handover refers to the process that MS starts communication with a new BTS while maintaing the
communication with the previous BTS. During the process, multiple channels are activated (funcation as diversity
in TCH) and handover happens between intra-frequency channels, which effectively reduces call drop rate. Soft
handover is carried out within the same frequency in different BTS and diversity signal make selection and
combination in RNC. Soft handover is classified into the operation of Iub radio link and of Uu activation set
update. Operation of Iub radio link include RADIO LINK ADDITION, RADIO LINK REMOVAL, and RADIO
LINK ADDITION AND REMOVAL. Operation of Uu activation set update is the same as operation of Iub radio
link. Therefore, by statistics of ACTIVE SET UPDATE message and ACTIVE SET UPDATE COMPLETE
message, we can get handover success rate.

Indicator Meaning
Concerning RNC intra-frequency hard handover, there are two cases: when Iur exists (handover when transmitting
fast-rate data), intra-frequency hard handover may be made instead of soft handover; when Iur does not exist, hard
handover may be made. Therefore making statistics of intra-frequency hard handover within RNC is meaningful. It
reflects the success rate of intra-frequency hard handover which can be basis to adjust radio parameter and is a
realatively key factor affecting users take on the network.
Indicator Definition
Intr-frequency hard handover include intra-RNC intra-frequency hard handover and inter-RNC intra-frequency hard
handover. As to intra-RNC intr-frequency hard handover, the statistics is made by cell (including handover in and
out) and by RNC; As to inter-RNC intra-frequency hard handover, it includes handover in and handover out.

handover success rate
Indicator Meaning
It reflects the success rate of inter-frequency hard handover which can be basis to adjust radio parameter and is a
realatively key factor affecting users take on the network.
Indicator Definition
Inter-frequency hard handover involves the change of radio frequency band between UE and UTRAN, the triggering

Indicator Definition
UMTS downlink scrambling code sets number is restricted to be 512, each cell is provided with a main scrambling
code. A main scrambling code corresponds to a spectrum spreading code tree, the value of each level of code tree
is defined as the value of spreading factor. Main scrambling codes are used to differentiate cells. Downlink
channel codes are used to differentiate users in different cells. The characteristics of this spreading code tree is that
the occupancy of one node will lead to the congestion of subcode tree nodes and directly connected high-level
nodes.
Therefore, cell code resources occupancy rate represents the ratio of assigned code resource to all code resource
which can correctly show the code resource of the serving cell.
