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.

3.1 RRC Setup Success Rate (Service) 3.1.1 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 3-1. 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 11 "Counter List."

3.2 RRC Setup Success Rate (Signaling) 3.2.1 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.

3.3 E-RAB Setup Success Rate (VoIP) 3.3.1 Description The E-RAB Setup Success Rate (VoIP) KPI indicates the E-RAB setup success rate of the voice over IP (VoIP) services in a cell or radio network. 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 3-2. 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 3-2 and Figure 3-3 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.

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 3-2 and Figure 3-3. 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.

3.3.2 Definition The E-RAB Setup Success Rate (VoIP) KPI is defined in Table 3-3. 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 3.3.1 "Description."

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.

4.1 Call Drop Rate (VoIP) 4.1.1 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 4-1. Figure 4-1 Abnormal E-RAB release

Draft A (2013-02-08)


10



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 4-1, 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.

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).

5.1 Intra-Frequency Handover Out Success Rate 5.1.1 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 5-1. The attempted HO counters are collected at point B. When the eNodeB sends an RRC Connection Reconfiguration message to the UE, it performs a handover. The eNodeB counts the number of times an intra-eNodeB intra-frequency HO is attempted in the source cell. The successful HO counters are collected at point C. The eNodeB counts the number of successful intra-eNodeB intra-frequency HOs in the source cell when the eNodeB receives the RRC Connection Reconfiguration Complete message from the UE.

Draft A (2013-02-08)

5 Mobility KPIs

Figure 5-1 Scenario for intra-frequency intra-eNodeB handover

Two scenarios are available for the inter-eNodeB HO, as shown in Figure 5-2 and Figure 5-3. 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 5-2 and Figure 5-3. 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.

5.2 Inter-Frequency Handover Out Success Rate The Inter-Frequency Handover Out Success Rate KPI is similar to the Intra-Frequency Handover Out Success Rate KPI. However, in this KPI, the target and source eNodeBs operate at different frequencies.

5.2.1 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 5.1.1 "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 5-1, 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 5-2, 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.

5.2.2 Definition The Inter-Frequency Handover Out Success Rate KPI is defined in Table 5-2. Note that the attempted HO and the successful HO counters are collected based on the description in section 5.2.1 "Description."

The HO includes both inter-eNodeB and intra-eNodeB scenarios. The intra-eNodeB HO scenario is shown in Figure 5-4. The attempted HO counters are collected at point B. When the eNodeB sends an RRC Connection Reconfiguration message to the UE, it performs a handover. The eNodeB counts the number of intra-eNodeB handover attempts in the target cell. The successful HO counters are collected at point C. The eNodeB counts the number of successful intra-eNodeB HOs in the target cell when the eNodeB receives an RRC Connection Reconfiguration Complete message from the UE. Figure 5-4 Intra-eNodeB HO
