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.


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.

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.


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.

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

Indicator Meaning

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.
