Introduction iManager M2000 is the most important Huawei tool for operation & maintenance of Huawei RAN. M2000 is a centralized management platform that can perform various operations including data configuration, alarm management, performance management and software management. M2000 follows the server-client concept. Server is centrally located in customer premises and is interconnected to various NE over IP network. It is normally running on Sun Microsystems servers and on Solaris operating systems together with Sybase as database. The M2000 client can be installed in a windows PC and requires only IP connectivity with M2000 server, correct firewall configuration and authentication user rights.
With M2000, we have a powerful, consistent, comprehensive and easy to use tool to perform basically all tasks related to operation & maintenance and most basic operations will be introduced in the following slides.

Tools used for Radio Network Optimisation (RNO) WNCS (1/8)
WNCS (WCDMA Neighbor Cell Support) is function that helps to optimize neighbor relations at the same frequency in WCDMA network: missing and unnecessary neighbor relations could be detected. Functions is based on GPEH (General Performance Event Handling) measurements. That is event triggered reporting concept. WNCS can also include, in analysis, related counters: • pmRlAddAttemptsBestCellSpeech • pmRlAddSuccessBestCellSpeech WNCS schedules recordings of GPEH events, collects ROP files and later processes and presents results. First step is to set-up new WNCS recording: “File” → “New Recording” → “NCS” For internal use only 96 © Nokia Siemens Networks
Tools used for Radio Network Optimisation (RNO) WNCS (2/8) Recording
Recording is performed by “NCS New Recording” wizard.
In order to perform WCDMA NCS measurement “Measure WCDMA” check box must be checked. Data to measure specifies the source to collect data from. Both GPEH events and Counters Only GPEH events Only Counters
Cell Set is cell filter that is used to select group of cells or RNC on which measurements will be performed
For internal use only 97 © Nokia Siemens Networks
Tools used for Radio Network Optimisation (RNO) WNCS (3/8) Basic principle of GPEH measurements
The RNC/RBS can log different types of events.
Recording starts at the beginning of the next 15-minute Result Output Period (ROP) after activation from OSS.
The events are collected in GPEH data files (main file and subfiles). The main file contains administrative information about GPEH recording, while subfiles contains recorded events. Depending on size of records, there could be more subfiles for each ROP.
Events are grouped in: RNC internal events: they are triggered by specific internal conditions (channel switch occurs, admission control request, terminates of connections, congestions, cell is not included in neighbor set...
Inter node events: Layer 3 protocol messages as specified by 3rd Generation Partnership Project (3GPP). There are several group of inter node events according to the protocols (RRC, NBPA, RANAP, RNSAP, PCAP, SABP)
All events have list of parameters that define events: EVENT_PARAM_SCANNER_ID, EVENT_PARAM_TIMESTAMP_HOUR(MINUTE/SECONDS/MILLISEC), EVENT_PARAM_EVENT_ID, EVENT_PARAM_UE_CONTEXT, EVENT_PARAM_C_ID_xy... For internal use only 98 © Nokia Siemens Networks
Tools used for Radio Network Optimisation (RNO) WNCS (4/8) Basic principle of GPEH measurements
Main GPEH events, needed for WNCS, are: INTERNAL_SOHO_DS_MISSING_NEIGHBOUR: Event is captured at reception of a measurement report for event 1a or event 1c, where the triggering cell is not included in neighbor set.
INTERNAL_SOHO_DS_UNMONITORED_NEIGHBOUR: event is captured when handover proposal is received, where the proposed cell is included in the neighbor set, but not included in the monitored set.
Parameters of this events contains information of best cell, RNC_ID, trigger cell scrambling code, RSCP/ECNO of trigger cell...
When GPEH measurements are completed, WNCS can processes files and represent results
WNCS measurements can cover several ROPs, but for each ROP period separate files, with recorded event data, will be created.
For internal use only 99 © Nokia Siemens Networks
Tools used for Radio Network Optimisation (RNO) WNCS (5/8) Overview report Results of WNCS measurements can be seen in “RNO WNCS Overview Report” window
All cells, which were subject of measurements, are listed in the rows. Columns of the table could be sorted in order to identify most critical cells regarding to missing neighbors, drop calls...
Double click on the cell will open new table (“RNO – WNCS Cell Report”) with more details regarding neighbor relations. For internal use only 100 © Nokia Siemens Networks
Tools used for Radio Network Optimisation (RNO) WNCS (6/8) RNO – WNCS Cell report (Defined Neighours)
In “Defined Neighbour” tab all neighbour relations that are defined are listed.
The list, for example, can be sorted according to the number of attempts to establish radio link (RL). So, relations with no or few RL attempts could be removed.
When the active set contains more than one cell, the monitored set (limited to 32 relations) will be a union of all defined neighbour relations for the cells in the active set. Those relations that could not fit into the monitored set are called unmonitored neighbours.
Unmonitored neighbour list could help to detect potential problems due to limited number of monitored relations. For internal use only 101 © Nokia Siemens Networks
Tools used for Radio Network Optimisation (RNO) WNCS (7/8) RNO – WNCS Cell report (Undefined Neighours) Undefined list of neighbour relations is created owing to GPEH INTERNAL_SOHO_DS_MISSING_ NEIGHBOUR events.
The list, for examle, can be sorted according to the number of possible RL adding attempts (or number of missing events). So, potential relations could be add.
Number of drop calls due to missing relations, average RSCP, time in active set and/or Average EcNo could also be considered when decisions are taking regarding adding neighbour relations.
Probable cell name is yielded due to algorithm that maps a cell name according to scrambling code, distance of potential cell, cell positions... “Unknown” is reported if algorithm could not map cell name. For internal use only 102 © Nokia Siemens Networks
