Troubleshooting LTE Networks to Improve Network Performance and Quality of Service

LTE Monitoring ChallengesTo meet the requirements of growing mobile data traffic, cellular operators are looking for an upgrade path for their current 3G networks that will enable the delivery of higher throughput and more services at a lower cost. Operators choose Long Term Evolution (LTE) for their network upgrade. LTE is designed to:

Increase bandwidth �Lower network and operational costs �Increase network performance for mobile data services �

To deliver the expected service quality in LTE networks, venders and operators need to adopt an advanced troubleshooting solution for the entire LTE deployment life cycle.

Troubleshooting Complex Multi-technology NetworksAt the time when vendors develop the infrustructure, and operators deploy LTE in their networks, many of them have multi-technology networks. As a result, these vendors and operators have to support interworking of both technologies and protocols.The troubleshooting solution has to present

Low coverage indication �Interworking issues between technologies such as GSM/UMTS, IMS and LTE �networks

The troubleshooting solution must provide the capacity and the correlation to support those essential requirements.

Analyzing the Quality of ServiceFirst class Quality of Service is the factor that will distinguish one operator from another in the highly competitive cellular market. With mobile data network usage growing and growing, operator’s troubleshooting needs are first and foremost to:

Monitor and quickly troubleshoot QoS issues and not just basic network �performance as has been done in the pastObtain a high capacity troubleshooting solution for their high-speed bandwidth �consuming networks.

RADCOM’s eDiamond Smart LTE analyzer provides solutions for all of these challenges.

RADCOM’s eDiamond eDiamond LTE Troubleshooting SolutionRADCOM’s eDiamond was designed for vendors and operators to provide understanding of LTE network problems and make LTE network analysis both simpler and faster.

eDiamond is used by LTE engineers for:

• Probe-basedtroubleshootinginlabsandduringtrials

• LTEmonitoringoflivenetworks’evaluation

eDiamond saves history data for long periods, and supports all known vendors of LTE : Ericsson, ALU, NSN, Huawei, ZTE , etc.

RADCOM’s probes are connected to the LTE interfaces, capturing the data and forwarding it to the eDiamond server which processes the captured data, correlates the sessions, calculates the KPIs and then stores it all for the engineer, to be used for analysis and troubleshooting.

Call TraceThe Call Trace capability presents the trace of a session with correlation of a number of interfaces. Vendors and operators use this ability to test multiple technologies and protocols, and to route calls. It supports real-time troubleshooting as well as historical analysis, for effective network management. The Call Trace functionality enables troubleshooting of handovers with other networks, such as GSM and UMTS

Real-time TroubleshootingeDiamond supports real-time network analysis 24x7 for troubleshooting sessions and protocol transactions between network elements and between network domains. It enables engineers to test interoperability as new services and elements are deployed.

Data Services AnalysiseDiamond supports mobile data analysis, thereby enabling vendors and operators to understand the quality of the customer experience. To ensure customer satisfaction, eDiamond includes the capability to track service availability and reliability. With eDiamond engineers can identify the source of service quality degradations and failures.

KPIsWith built-in and customized KPIs, vendors and operators set measurements for the signaling to view the network (which is an independent source). Using the KPIs, engineers easily identify a variety of network issues. The KPIs enable detection of problems by protocols, services, locations, network elements, subscribers, hand-sets and APNs. With the drill-down from the KPI results to the call trace, an engineer can easily pinpoint the source of a problem.
