Product Description 1 Positioning and Characteristics


Copyright © Huawei Technologies Co., Ltd.1

1 Positioning and Characteristics

1.1 PositioningThis document is intended for the SONMaster V100R014.

Background

With the development of SingleRAN and heterogeneous network (HetNet), hybrid

networking scenarios with multiple radio access technologies (RATs) have become more andmore popular. Consequently, coordination and optimization between different RATs have

become operators' crucial concerns.

To meet this challenge, Huawei has introduced the SingleSON solution, a centralized network

optimization solution for the self-organizing network (SON).

Positioning

The SONMaster is an important part of Huawei SingleSON solution. It provides the

automatic optimization for GSM, UMTS, and LTE, and automatic coordination among GSM,

UMTS, and LTE. In this way, the SONMaster improves operation and maintenance (O&M)

efficiency and lowers O&M costs.

1.2 Characteristics

Independent Deployment and Inter-Vendor Network Optimization

The SingleSON solution includes the following SON functions:

LTE D-SON on eNodeBs

Self-configuration C-SON on the U2000

Inter-RAT and inter-vendor SON functions on the SONMaster

Because of the importance of inter-RAT and inter-vendor SON functions, the SONMaster isindependently deployed and can interconnect with networks of other vendors architecturally.



iManager SONMaster




Advanced Design Platform, Large Capacity, and Phased Deployment

The SONMaster uses Huawei ATAE cluster system, which is characterized by large capacity,high reliability, and easy capacity expansion.

Inter-RAT Coordination, Centralized SON Platform, and Low O&M Costs

The SONMaster centrally collects, analyzes, and processes call history record (CHRs) or MRs

for multiple RATs to implement inter-RAT coordination. For networks using different RATs

and multi-layer networks, the SONMaster provides a centralized SON platform to implementautomatic control. In this way, the SONMaster greatly improves the network configuration,optimization, and maintenance efficiency and consequently decreases O&M costs.

Automatic Network Parameter Configuration and Improved O&M Efficiency

The SONMaster can detect and add neighboring cells and missing neighboring cells andremove redundant neighboring cells.

The SONMaster can check scrambling code configurations for UMTS cells and locate cellsthat use the same frequency and scrambling code. For problem cells, the SONMaster providesrecommended scrambling code configurations and delivers the configurations to the network

element (NE) in question.

The preceding operations are automated and therefore misoperations are prevented and the

network O&M efficiency is improved.

1.3 Position on the Network

Figure 1-1 shows the position of the SONMaster on the network.

Description. You can contact Huawei technical support to obtain this document.

Table 3-1 Self-optimization functions provided by the SONMaster

Function Subfunction Description

ANR GSM ANR GSM ANR automatically detects missing and

redundant neighboring cells. By adding missingneighboring cells and deleting redundant

neighboring cells, GSM ANR prevents KPIdeterioration caused by inappropriate neighborrelationships.

UMTS ANR UMTS ANR applies to Huawei and Ericsson

networks. During ANR, missing neighboring cellsare added, redundant neighboring cells are deleted,and neighboring cell priorities are optimized. UMTS

ANR automatically maintains the integrity and

validity of neighbor relationships within the UMTSsystem, between the GSM and UMTS systems, and

between the UMTS and LTE systems.

UMTS

Neighboring Cell

Optimization forBlind Handover

A blind handover is not measurement-based so that

it is performed without the knowledge of the signal

quality of the target cell. UMTS neighboring celloptimization for blind handover automaticallymanages neighboring cells for blind handover.

CCO UMTS CCO The SONMaster provides UMTS Coverage and

Capacity Optimization (CCO) for wireless networksof Huawei and Ericsson. Based on automatic

analysis, UMTS CCO implements better coverageand load balancing on such networks. This helpsreduce network problems caused by coverage

exceptions and load imbalance, and improve

network performance.

LTE CCO The SONMaster provides LTE Coverage and

Capacity Optimization (CCO) for wireless networksof Huawei and Ericsson. Based on automatic

analysis, LTE CCO implements better coverage andload balancing on such networks. This helps reducenetwork problems caused by coverage exceptions

and load imbalance, and improve network

performance.

IDO UMTS SC

Self-Optimization

The SONMaster provides the UMTS SC

self-optimization feature, which allows optimizingthe radio access networks for Huawei and Ericsson.UMTS SC Self-Optimization detects whether theserving cells and their neighboring cells have SC

conflicts with the target cell based on call history

records (CHRs), engineering parameters, and theRNC configuration parameters. Then, the

SONMaster reallocates SCs to the conflicting cells.By optimizing scrambling codes (SCs), UMTS SC

self-optimization prevents KPI deterioration caused by SC conflicts.

MLB UMTS Inter-Band

MLB

The SONMaster provides the UMTS Inter-Band

MLB optimization, which allows optimizing theradio access networks for Huawei and Ericsson.

UMTS Inter-Band MLB optimization optimizes

parameters related to idle-mode cell reselection anddirected retry decision (DRD) (or HSDPA

Inter-frequency Load Sharing). This enables UEs to

distribute in cells of different frequency bands andresolves inter-frequency load imbalance caused bydifferent coverage capabilities.

UMTS Hetnet Idle

Mode MLB

UMTS Hetnet Idle Mode MLB can be achieved by

optimizing cell reselection parameters for UEs in

idle mode so that UEs are evenly distributed inmacro and micro cells.

LTEInter-Frequency

Idle Mode MLB

LTE Inter-Frequency Idle Mode MLB optimizationadjusts the inter-frequency reselection parameters

periodically so that UEs in idle mode distribute

appropriately among multiple frequencies. Thisreduces signaling congestion caused by imbalanced

inter-frequency traffics and addresses the problem ofimbalanced usage of air interfaces.

MRO UMTS MRO UMTS MRO automatically analyzes and determines

whether the handover parameters are properly set

based on measurement reports (MRs), performancecall history records (PCHRs) or call history records(CHRs), and performance parameters. If not, theSONMaster automatically adjusts the handover

parameters. This helps reduce radio link failures(RLFs) and unnecessary handovers.

Product Description 5 Operation and Maintenance



5 Operation and Maintenance

5.1 Comprehensive System Security MechanismThe SONMaster system provides a comprehensive security mechanism to ensure the system

security and the confidentiality of stored data. This mechanism works as follows:

Users can harden operating systems and databases to ensure the SONMaster system

security.

The messages exchanged between the SONMaster server and other devices areencrypted to ensure data transmission security.

The SONMaster system protects user data, manages user rights, controls user accesses,

monitors user behavior, and periodically audits user operations with logs.

5.2 Intelligent Management of the ATAE Cluster SolutionAll the boards (except the OSMU) in the ATAE cluster solution are not configured with hard

disks. The SAN Boot technique is applied to these boards to boot an operating system fromdisk arrays. When a board is faulty, the SAN Boot technique maps the boot volume of the

faulty board onto a new board that replaces the faulty board to minimize the impact.

Intelligent hardware management of the OSMU works as follows:

The OSMU runs on an independent board. It centrally manages data and provides batchoperations that include batch adjustments on IP addresses, time, routes, and user

passwords and batch powering on or off of boards. In this way, the OSMU improves the

O&M efficiency. The OSMU provides a device panel where users can check the device status in real time

and maintain devices.

The OSMU provides the centralized task management function. With this function, userscan query ongoing tasks on the OSMU in real time. In this case, users are aware ofongoing tasks on the OSMU before performing an important operation. This prevents

redundant tasks.

The OSMU provides the internal centralized backup function. This function centrally backs up the operating system data and static data on each service board to disk arrays.

The backup process is fast, efficient, and cost-effective.

During activation, the OSMU can automatically deploy OS software and database

software on boards.
