Empirix E-XMS: IuB Analysis

Perform. Assure customer experience with end-to-end visibility across complex mobile environments.

Delivering quality services over Mobile Broadband (MBB) networks is extremely complex. Smart phones and the innovative applications they spawned have put a tremendous strain on network resources. To meet this demand, Mobile Network Operators (MNOs) have made extensive infrastructure investments, deploy-ing new technologies as rapidly and cost-effectively as possible. Today it is not uncommon to find organizations operating a combined 2G/3G/4G environment. Maintaining high quality communications – be they voice, video or data – under changing mobile conditions is quite challenging.

Without complete visability into this environment, MNOs cannot truly understand the customer experience. Today, many operators maintain a Radio Frequency (RF) monitoring solution as a large percentage of problems are attributed to this ele-ment. By analyzing the IuB interface, Empirix provides true end-to-end service assurance and troubleshooting for UMTS providers.

Empirix Service Assurance: Linking Radio Metrics with Network Analytics

With IuB analysis, Empirix E-XMS Service Assurance solutions span both the Core and Universal Terrestrial Radio Network Access Network (UTRAN). Monitor-ing the IuB interface between radio network controllers and Node B provides an understanding of how Quality of Service (QoS) is affected by radio link per-formance. Monitoring RF performance reveals reasons for dropped calls, high speed data bandwidth leakages, poor voice quality and other issues resulting from inconsistent communications between user equipment and base stations.

A complete analysis of RF performance, resource usage, handover success rates, setup success rates and other key analysis provides an understanding of how UTRAN performance affects QoE. Adding IuB analysis to service assurance programs provides MNOs with:

¤ Complete end-to-end customer experience analysis from core to RAN ¤ An analysis of RF performance on a per user, per Node B and per cell basis ¤ Verification of handovers ¤ An analysis of service set-up procedures ¤ Quality of Experience and Quality of Service assurance in UTRAN networks ¤ Geo-localization of call events ¤ Accurate GTP-U payload analysis ¤ Efficient troubleshooting

BenefitsReduce the time it takes to understand the root cause of problems - in the RAN or CORE

Increase efficiency with integrated RF analysis on a per location or per sub-scriber basis

Improve the ROI of Drive Tests by guid-ing teams to areas of poor performance

Lower CAPEX and OPEX with a single solution requiring only software license updates to add IuB and additional capa-bilities

Eliminate doubt with a true end-to-end analysis of customer Quality of Experi-ence

Preempt issues with long-term, continu-ous analysis that identifies service degra-dation issues before they can impact customers

Speed ROI and optimize infrastructure investments by identifying bandwidth, customer experience and quality issues

is ideal for verifying SLA information, reducing root case isolation time and increasing analysis capabilities. Empirix portable testing solutions not only report on issues surrounding the Radio Network Controllers (RNCs) but also the entire UTRAN and MBB networks.

Supported Protocols:

Empirix provides IuB analysis via IP and monitors the following protocols:

¤ NBAP ¤ FP for RRC ¤ RRC – FACH, RACH, PCCH, DCH and NAS (GMM, SM, CC, SM)

¤ Correlated IuB and Iu analys

KPI Analysis:

UTRAN Radio KPIs:

¤ BLER ¤ Quality Estimate ¤ Throughtput ¤ Main procedure latency (e.g., RRC connection set-up)

Iub KPIs:

¤ Drop call type per service and activ-ity (RAB, NAS, CC, MM, etc.)

¤ Iu Release causes per UE, per activ-ity type, per traffic classes

¤ Iu Release causes vs. EC/No (RSCP) per activity type

¤ Call duration per activity type

Flexible Deployment Models

Empirix offers a wide range of multi-service probe designs as well as management tools for the testing and monitoring of MBB environments.

In-service Monitoring

For MNOs, continuous monitoring of the entire network with Empirix MSP in-line probes is essential for proactive assurance of the customer experience. Additionally, it provides actionable information enabling more informed decision-making for network planning projects, new service intro-ductions and revenue development models.

Portable Analysis

Empirix also offers portable, handheld devices that professional service provid-ers, network equipment manufactures and consultants can use to quickly diagnose and effectively inves-tigate network performance is-sues. The Empirix IPXPlorer probe
