1 Positioning and Characteristics

Positioning and Characteristics

1.1 Positioning This 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 and more 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 is independently deployed and can interconnect with networks of other vendors architecturally.

Issue 03 (2014-07-27)

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 MR s 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 implement automatic 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 and remove redundant neighboring cells. The SONMaster can check scrambling code configurations for UMTS cells and locate cells that use the same frequency and scrambling code. For problem cells, the SONMaster provides recommended 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.

Function

Subfunction

Description

ANR

GSM ANR

GSM ANR automatically detects missing and redundant neighboring cells. By adding missing neighboring cells and deleting redundant neighboring cells, GSM ANR prevents KPI deterioration caused by inappropriate neighbor relationships.

UMTS ANR

UMTS ANR applies to Huawei and Ericsson networks. During ANR, missing neighboring cells are 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 UMTS system, between the GSM and UMTS systems, and between the UMTS and LTE systems.

UMTS Neighboring Cell Optimization for Blind 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 cell optimization for blind handover automatically manages neighboring cells for blind handover.

UMTS CCO

The SONMaster provides UMTS Coverage and Capacity Optimization (CCO) for wireless networks of Huawei and Ericsson. Based on automatic analysis, UMTS CCO implements better coverage and load balancing on such networks. This helps reduce 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 networks of Huawei and Ericsson. Based on automatic analysis, LTE CCO implements better coverage and load balancing on such networks. This helps reduce network problems caused by coverage exceptions and load imbalance, and improve network

IDO

UMTS SC Self-Optimization

The SONMaster provides the UMTS SC self-optimization feature, which allows optimizing the radio access networks for Huawei and Ericsson. UMTS SC Self-Optimization detects whether the serving cells and their neighboring cells have SC conflicts with the target cell based on call history records (CHRs), engineering parameters, and the RNC 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 the radio access networks for Huawei and Ericsson. UMTS Inter-Band MLB optimization optimizes parameters related to idle-mode cell reselection and directed retry decision (DRD) (or HSDPA Inter-frequency Load Sharing). This enables UEs to distribute in cells of different frequency bands and resolves inter-frequency load imbalance caused by different 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 in macro and micro cells.

LTE Inter-Frequency Idle Mode MLB

LTE Inter-Frequency Idle Mode MLB optimization adjusts the inter-frequency reselection parameters periodically so that UEs in idle mode distribute appropriately among multiple frequencies. This reduces signaling congestion caused by i mbalanced inter-frequency traffics and addresses the problem of imbalanced usage of air interfaces.

UMTS MRO

UMTS MRO automatically analyzes and determines whether the handover parameters are properly set based on measurement reports (MRs), performance call history records (PCHRs) or call history records (CHRs), and performance parameters. If not, the SONMaster automatically adjusts the handover parameters. This helps reduce radio link failures (RLFs) and unnecessary handovers.

5 Operation and Maintenance

Operation and Maintenance

5.1 Comprehensive System Security Mechanism The 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 are encrypted 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 Solution All 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 from disk arrays. When a board is faulty, the SAN Boot technique maps the boot volume of t he 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 batch operations 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, users can query ongoing tasks on the OSMU in real time. In this case, users are aware of ongoing tasks on the OSMU before performing an important operation. This prevents redundant tasks.





Issue 03 (2014-07-27)

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.
