2 Accessibility KPIs
Accessibility KPIs are used to measure the probability that a user accesses the network and
requests services in the given operating conditions. The service provided by the E-UTRAN is
defined as EPS/E-RABs. (EPS is short for evolved packet system, and E-RAB is short for
E-UTRAN radio access bearer). Radio Resource Control (RRC) connections and System
Architecture Evolution (SAE) setups are the main procedures whose performance is measured
by accessibility KPIs.
2.1 RRC Setup Success Rate (Service)
2.1.1 Description
According to 3GPP TS 36.331, the RRC connection setup procedure is triggered by different
causes, which are identified in the "establishmentCause" field in an RRC Connection Request
message as emergency, highPriorityAccess, mt-Access, mo-Signaling, mo-Data, or
delayTolerantAccess-v1020. The UE sets the establishmentCause in accordance with the
information it receives from upper layers. The mo-signaling cause is a signaling-related cause.
All other causes are service-related causes. The accessibility KPI evaluates the RRC setup
success rate using service-related causes in a cell or radio network.
The RRC Setup Success Rate (Service) KPI is calculated based on the counters measured at
the eNodeB when the eNodeB receives an RRC Connection Request message from the UE, as
shown in Figure 2-1. The number of RRC connection attempts is collected by the eNodeB at
measurement point A, and the number of successful RRC connections is counted at
measurement point C. The related counters are discussed in chapter 9 "Counter List."

2.2 RRC Setup Success Rate (Signaling)
2.2.1 Description
The RRC Setup Success Rate (Signaling) KPI indicates the RRC setup success rate of the
signaling-related cause (mo-signaling) in a cell or radio network.
Like the RRC Setup Success Rate (service), the RRC Setup Success Rate (Signaling) KPI is
used to calculate the RRC setup success rate only when the "establishmentCause" field is set
to mo-signaling in a cell or radio network.

2.3 S1SIG Connection Setup Success Rate
2.3.1 Description
The S1SIG Connection Setup Success Rate KPI indicates the success rate of signaling
connection setups over the S1 interface. This KPI includes counters such as the number of
setup attempts of S1 signaling connections related to UEs and the number of successful setups
of S1 signaling connections related to UEs.
The number of setup times of S1 signaling connections related to UEs is incremented by 1
each time when the eNodeB sends an INITIAL UE MESSAGE to the MME or receives the
first message from the MME. INITIAL UE MESSAGE is the first S1 message that the
eNodeB sends to the MME. It contains the NAS configuration information related to UEs,
based on which the MME sets up S1 signaling connections for UEs. The first S1 message sent
by the MME may be INITIAL CONTEXT SETUP REQUEST, DOWNLINK NAS
TRANSPORT, or UE CONTEXT RELEASE COMMAND. Receiving any of these messages
indicates that the S1 signaling connection is set up successfully.
As shown at point A in Figure 2-2, the L.S1Sig.ConnEst.Att counter is incremented by 1
when the eNodeB sends an INITIAL UE MESSAGE to the MME.
As shown at point B in Figure 2-2, the L.S1Sig.ConnEst.Succ counter is incremented by 1
when the eNodeB receives the first S1 message sent from an MME after sending an INITIAL
UE MESSAGE to the MME.

voice over IP (VoIP) services in a cell or radio network.
eRAN7.0 KPI Reference 2 Accessibility KPIs
Draft B (2014-04-05) Huawei Proprietary and Confidential

According to 3GPP TS 36.300 and 3GPP TS 36.413, the counters related to this KPI are
measured when the eNodeB receives an E-RAB Setup Request message or an Initial Context
Setup Request message from the mobility management entity (MME), as shown in Figure 2-2
and Figure 2-3. The E-RAB is part of the Evolved Packet Service (EPS) bearer. According to
3GPP TS 23.401, an E-RAB is one or more Service Data Flows between UE and an EPC. The
E-RAB identity remains unique for the UE even if the UE-associated logical S1-connection
(S1 bearer) is released during periods of user inactivity. The E-RAB consists of both the
E-RAB radio bearer (between the eNodeB and the UE, which is the same as the radio bearer
defined in the EPS bearer) and the corresponding S1 bearer (between the eNodeB and the
MME).
Figure 2-2 and Figure 2-3 show two scenarios: MME-initiated E-RAB setup (Scenario A) and
UE-triggered E-RAB setup (Scenario B). Scenario B is triggered by the radio bearer setup.
Initial Context Setup Request messages are exchanged between the eNodeB and the MME. If
the E-RAB Setup Request message or Initial Context Setup Request message requires
multiple E-RAB setups at the same time, specific counters are incremented for each E-RAB.

Figure 2-3 Measurement points for UE-triggered E-RAB setup
The eNodeB collects the number of E-RAB connection setup attempts at measurement point
A, and the number of successful E-RAB connections is counted at measurement point B, as
shown in Figure 2-2 and Figure 2-3. Note that the eNodeB needs to specify the Quality of
Service (QoS) Class Identifier (QCI) for VoIP in the E-RAB setup message.
The voice service can be identified by the QoS information, particularly the QCI in the
E-RAB Setup Request message. In general, QCI 1 is assigned to the voice service.
2.4.2 Definition
The E-RAB Setup Success Rate (VoIP) KPI is defined in Table 2-4. Note that the number of
E-RAB connection setup attempts (VoIP) and the number of successful E-RAB setup
connections (VoIP) are collected based on the descriptions in section 2.4.1 "Description."

3 Retainability KPIs
Retainability KPIs indicate the network's capability to retain services requested by a user for a
desired duration once the user is connected to the services. Retainability KPIs are important in
evaluating whether the system can maintain a certain level of service quality.
3.1 Call Drop Rate (VoIP)
3.1.1 Description
The Call Drop Rate (VoIP) KPI indicates the call drop rate of the VoIP services in a cell or
radio network. A VoIP call drop occurs when the VoIP E-RAB is abnormally released. Each
E-RAB is associated with QoS information. Usually, the QCI of VoIP services is 1.
An E-RAB consists of a radio bearer and a corresponding S1 bearer. Any abnormal release of
either bearer causes a call drop. A release is defined as abnormal by its release cause
according to 3GPP TS 36.413.
Two procedures can be performed to release E-RABs: E-RAB Release Indication and UE
Context Release Request, as shown in Figure 3-1.

When the eNodeB sends an E-RAB Release Indication message to the MME or a UE Context
Release Request message to the MME as shown in Figure 3-1, the abnormal E-RAB release
counter is incremented if the bearer to be released carries data and the release cause is not
"Normal Release", "Detach", "User Inactivity", "CS Fallback triggered", "UE Not Available
for PS Service", or "Inter-RAT Redirection". If the message contains several E-RAB ID IEs
(in the E-RAB To Be Released List IE), the counter will be incremented for each individual
E-RAB.

4 Mobility KPIs
Mobility KPIs are used to evaluate E-UTRAN mobility performance, which is critical to
customer experience. Three categories of mobility KPIs are defined based on the following
handover types: intra-frequency, inter-frequency, and inter-Radio Access Technology (RAT).
4.1 Intra-Frequency Handover Out Success Rate
4.1.1 Description
The Intra-Frequency Handover Out Success Rate KPI indicates the intra-frequency handover
success rate from the local cell or radio network to the intra-frequency neighboring cell or
radio network. An intra-frequency handover (HO) includes both inter-eNodeB and
intra-eNodeB scenarios.
The intra-eNodeB HO scenario is shown in Figure 4-1. The attempted HO counters are
collected at point B. When the eNodeB sends an RRC Connection Reconfiguration message

Figure 4-1 Scenario for intra-frequency intra-eNodeB handover
Two scenarios are available for the inter-eNodeB HO, as shown in Figure 4-2 and Figure 4-3.
The HO attempts are collected at point B. When the source-eNodeB (S-eNodeB) sends an
RRC Connection Reconfiguration message to the UE, it decides to perform an inter-eNodeB
HO. In this KPI, the source and target cells of the handover operate at the same frequency.
The number of inter-eNodeB intra-frequency HO attempts is measured at the source cell.
The number of successful inter-eNodeB intra-frequency HOs is collected at point C, as shown
in Figure 4-2 and Figure 4-3. During a handover with the source and target cells at the same
frequency, the number of successful inter-eNodeB intra-frequency HOs is measured in the
source cell. This measurement occurs when the S-eNodeB receives a UE Context Release
message from the target-eNodeB (T-eNodeB) or a UE Context Release Command message
from the MME, indicating that the UE T-eNodeB is successfully attached to the T-eNodeB.

4.2.1 Description
The Inter-Frequency Handover Out Success Rate KPI indicates the inter-frequency handover
success rate from the local cell or radio network to the inter-frequency neighboring cell or
radio network. Note that the measurement points for the associated counters are the same as
those for the intra-frequency HO scenario described in section 4.1.1 "Description." The target
LTE cell operates at a frequency different from that of the source LTE cell, which is the only
difference between this KPI and the Intra-Frequency Handover Out Success Rate KPI.
As shown in Figure 4-1, if the source and target cells operating at different frequencies are
controlled by the same eNodeB, the eNodeB counts the number of intra-eNodeB
inter-frequency HO attempts at point B and the number of successful intra-eNodeB
inter-frequency HOs at point C in the source cell. As shown in Figure 4-2, if the handover
source and target cells are operating at different frequencies, the eNodeB counts the number
of inter-eNodeB inter-frequency HO attempts at point B and the number of successful
intra-eNodeB inter-frequency HOs at point C in the source cell.

users in the cell to be sampled every second and then calculates the average value of these
samples throughout the measurement period.
8.4.2 Definition
The Average User Number KPI is defined in Table 8-4. The formula is mapped to its
corresponding counters.

8.5.1 Description
The Maximum User Number KPI evaluates the maximum number of users in
RRC_Connected mode of a cell in a certain period of time. This value is calculated based on
samples. The eNodeB records the number of users in the cell to be sampled every second and
then calculates the maximum value of these samples throughout the measurement period.

9 Counter List
Table 9-1 provides a list of all the counters relevant to KPI calculation. In each KPI
specification, one or more parameters are used to calculate the KPI, as shown in the KPI
formula. Each parameter is mapped to a counter. For details on each counter, see eNodeB
Performance Counter Reference.
Note that only QCI 1 is used for VoIP service (conversational voice). According to Table 6.1.7
in 3GPP TS 23.203, QCI 7 can also be assigned to non-conversational voice. In this document,
QCI 7 is not considered to be part of the VoIP service in KPI calculation.
The counters listed in the following table are described in eNodeB Performance Counter
Reference.
