1 Introduction

1.1 PositioningThis document is intended for the iManager M2000 AP Manager V100R002.

1.1.1 BackgroundThe 3G indoor coverage problems such as high frequency band and poor penetration

always present subscribers and operations with difficulty.

The wide application of 3G requires the operator to provide quality radio signal

coverage. It is, however, difficult to ensure high indoor signal quality because

buildings can block radio signals.

Indoor signal coverage is completely different from outdoor signal coverage.Outdoor coverage features the plane coverage in large areas. The 3G applications

required by subscribers in indoor areas such as home and small office and home

office (SOHO) feature small capacity and mini-area. The required mode for

indoor coverage is dot coverage.

When attempting to solve the indoor coverage problem, the operator mustconsider the operation expenditure for installation and maintenance, apart fromthe capital expenditure on equipment.

Based on the characteristics of indoor coverage and user requirements, Huawei

develops the uBro solution to solve the problem about the indoor coverage of 3G

signals.

1.1.2 Network Architecture

Figure 1-1 shows the network architecture of the uBro solution.






of 30

Figure 1-1 Network architecture of the uBro solution

Table 1-1 lists the NEs that are newly introduced to the uBro solution.

Table 1-1 Newly introduced NEs in the uBro solution

Equipment Function

AP The access point (AP) provides access to the UMTS network. It

provides the functions such as radio modulation and

demodulation, radio resource management, and power control.

AG The access gateway (AG) is located on the operator's Intranet. It

controls and manages APs and provides routes to other NEs.

Clock server The clock server acts as a clock source and provides accurate

clock signals for APs. The clock server can be placed in a fixednetwork and connected to the DSLAM or the BAS. It can also be

placed in a mobile network.

AHR The AP home register (AHR), which is the home server of APs, is

placed on the operator's Intranet. It stores the location information

of UMTS APs, account information, and MS access control list.

AP Manager The AP Manager is the AP management system. It allows you to

manage APs in a centralized manner.






of 30

Equipment Function

AAA The authorization, authentication, and accounting (AAA) server

authenticates the identity and authority of a user and records the

user's activities.

1.1.3 Benefits

Benefits for the Operator

By using APs, the operator can obtain the following benefits:

The operator can effectively solve the problem about the indoor coverage of the

UMTS network, thus better fulfilling the users' requirements for 3G services.

The expenditure for installing and maintaining the uBro system is low. The uBro

system supports automatic software upgrade and configuration, and automatic

network planning. Therefore, the uBro system can be rapidly and widely

deployed by the operator.

Benefits for Terminal Users

By using APs, terminal users obtain the following benefits:

Terminal users can enjoy 3G network services of higher quality at a lower price at

home because the uBro system does not occupy the radio access resources of the

NodeB.

The UMTS AP supports user license management and access control. Thisprevents an AP from being used by an unauthorized UE. Thus, the expenditure on

APs is effectively reduced.

1.1.4 Introduction to the AP ManagerThe AP Manager is a platform developed by Huawei to manage APs. On this platform,

you can operate and maintain the uBro solution.

The AP Manager provides the following functions:

Configuration management

Software management

Fault management

Task management

Security management

Log management

1.1.5 Position of the AP Manager in the uBro System

1.2 Product FeaturesPowerful Operation and Maintenance Functions

The AP Manager provides the following functions:


Software management

Fault management

Task management

Security management

Log management

The AP Manager allows you to configure APs and upgrade the AP software in batches.

You can also upload the log files and performance files of APs to the AP Manager.

Apart from the main functions, the AP Manager supports the following services:

Multiple file servers

Daylight saving time (DST) and Network Time Protocol (NTP)

License-based AP management

Configuring custom AP parameters in batches by importing files

Configuring AP zone parameters in batches by importing files

Fault subscription and AP alarm management

Linux operating system and the Oracle database

Integrated Processing Platform

The AP Manager adopts the Advance Telecommunications Application Environment

(ATAE) hardware platform. The ATAE hardware platform, which is developed by

Huawei, is a professional and highly integrated carrier-class platform with high






of 30

performance. Dedicated to telecommunication applications, the ATAE platformincorporates the carrier grade Linux (CGL) technology to implement the large capacity,

high performance, high reliability, and high scalability.

Operation Interface Base on the Web

The AP Manage provides a web-based operation and maintenance interface that allowsyou to perform centralized operation and maintenance on the AP. The interface is easy

to be installed and operate.

Reliable System

The AP Manager operates on the ATAE platform. The stable operation and high

performance of the ATAE platform ensures the high reliability of the AP Manager.

The system data of the AP Manager is stored on the database of the AP Manager server.The high security and the backup and restore mechanism of the database ensure the

high reliability of the system data.

Reliable SoftwareThe AP Manager adopts the 3-layer Java 2 Platform Enterprise Edition (J2EE)

structure with Enterprise Java Bean (EJB) as the core.The stable and secure JAVA

platform ensures the reliability of the AP Manager software.

The AP Manager limits the number of login attempts. During a specific period, if the

number of successive illegal login attempts of a user exceeds the maximum number of

login attempts, the AP Manager locks the user and records the login failure in thesecurity log. After a certain period, the AP Manager automatically unlocks the user.

The AP Manager provides the function of prompting you to confirm important or

global operations.

If no operation is performed within a long period after you log in to the AP Manager,

the current user is forced out of the system.

2 Architecture

2.1 OverviewThe AP Manager uses the browser/server mode.

The AP Manager server application runs on the AP Manager server. When managingAPs, you can log in to the AP Manager server by using the web browser on your client

PC. This chapter describes the hardware and software architecture of the AP Managersystem.

2.2 Hardware Architecture

2.2.1 Overview of the Hardware Architecture

A typical AP Manager system consists of the following components:

A server or servers

A client or clients

Other networking devices

AP Manager server consists application server and database server.

If few APs are managed by the system, you can install the application server anddatabase server on the same ATAE server board.

2.2.2 Physical Structure of the AP Manager Based on ATAE

Figure 2-1 shows the physical structure of the AP Manager when the ATAE board acts

as the AP Manager server in the single-server system.

Figure 2-1 Typical configuration of the AP Manager in the single-server system

Figure 2-2 shows the physical structure of the AP Manager when the ATAEboard acts as the AP Manager server in the HA system.

Table 2-1 Description of the devices at the server side (HA system)

Device Description

Active serverblade

The server of the AP Manager system. Running the AP

Manager server software, the active and standby serverblades work together and use the Veritas Cluster Server(VCS) software to monitor and switch over the serverresources.

Standby serverblade

The redundancy server of the active server. When theresources on the active server are faulty, the resourcescan be switched over to the standby server bladethrough the VCS.

Disk arrayProvides high-availability storage space for the activeserver. When the active server is faulty, the VCS mountsthe disk array to the standby server. In the uBro solution,the disk array is shared by the AHR, AP Manager,M2000, and AAA. The AP Manager server and M2000

server shares four disks on the disk array. These disksare made to a RAID 1 + 0 and identified by a logical unitnumber (LUN). In this case, the data stored on the diskarray is secure.
