Ericsson Mobility Management Engine (MME) xStats Adapter
Ericsson's Serving GPRS SUPPORT NODE – Mobility Management Entity (SGSN-MME) provides packet-data switching and mobility/session management in GSM, WCDMA and LTE networks. It has excellent, proven ISP and extensive functionality, which optimizes network operation and minimizes total cost of ownership.
The Ericsson MME xStats Adapter from SevOne pulls metrics from the Ericsson MME for the following areas:
- Bearer Control Objects (VS.HM) - A collection of objects and indicators that provide key indicators as to how the voice bearer channels are performing. This includes successes or denies for a number of reasons, including authentication.
- Attach and Handoff Objects (VS.MM) - A collection of counters and gauges providing data on the success and failure of handing calls off to other functions, such as the SGW and HSS.
- Security Statistics (VS.SEC) - A collection of counters and gauges that monitor the security aspects of the MME functions, such as Number of Authentication Information Retrieval procedures in the MME, number of attempted Security Mode Control procedures started within this MME area for a subscriber using a USIM, and number of successful Security Mode Control procedures within this MME area for a subscriber using a USIM.
These Key Performance Indicators are representative of what can be achieved with SevOne’s xStats adapter for the Ericsson MME. SevOne can provide additional metrics based on your monitoring needs.
Below is an example of how SevOne graphs the number of security mode control procedures within a MME. This allows operators to watch for MME overload or failure and security issues. It also provides input to traffic engineers and architects to help plan pooling and redundancy strategies. SevOne automatically baselines these statistics, allowing alerts to be triggered based on hard thresholds or deviations from expected performance.
What Are the Benefits?
SevOne’s xStats adapters provide the fastest, most flexible way to collect multiple data sources and present them in side-by-side dashboards, even when SNMP is not available. For example, users can build monitoring dashboards that look at transport statistics from networks alongside response time metrics from active testing solutions and probes.
The Ericsson MME xStats Adapter, available through SevOne Professional Services is designed to provide the insight you require, without having to cross-reference multiple Element Management Systems and Network Management Systems at the same time.
