WiBAS-2X Network Architecture

Introduction A WiBAS-2X network is based on a point-to-multipoint architecture and is intended for wireless Line-Of-Sight (LOS) coverage in areas with cell sectorization. A cell is a geographical area covered by a WiBAS-2X system incorporating a Base Station (BS), at the center of the cell, and several Terminal Stations (TS) scattered within the cell, as depicted below:

A cell is physically divided into – usually four (or six) – sectors and served by the Base station Radio System (BRS), the outdoor part of the BS. The BRS controls the radio links, between the BS and the scattered TS and communicates with the outdoor part of each TS, the Terminal station Radio Systems (TRS). The indoor part of the BS, IBAS (Intracom Broadband Access System), aggregates traffic from all TS and provides the network interfaces to the backbone. The MSAD (Multi-Service Access Device), the indoor part of the TS, provides the user interfaces. All WiBAS-2X network elements, for as many systems, may be configured, controlled and monitored remotely through an advanced Network Management System, the wBBMS.

Equipment Description

Introduction This section describes in detail the WiBAS-2X equipment.


17

IBAS

Description IBAS constitutes the INTRACOM TELECOM answer to the Multi-Service Access Node (MSAN) requirements of Legacy and Next Generation Networks (NGN). As part of the WiBAS Base Station, IBAS is used to aggregate IP, TDM and ATM traffic from all terminal stations and connect to the backbone network. Further, customers residing in the same building as the BS can also be served by IBAS, via its E1 and Ethernet interfaces. IBAS employs wireline as well as wireless technologies to provide wireless broadband access and wireless backhauling. As a true Multi-Service Access Node (MSAN), IBAS can provide both narrowband (POTS, ISDN) and broadband xDSL (e.g. ADSL /2/2+, G.shdsl) access services. IBAS includes the baseband modems for each radio sector, the control logic for the whole system, the uplink network interfaces and the wireline access interfaces. IBAS features a high-bandwidth backplane, high aggregation capacity, high-speed network interfaces and advanced protection mechanisms. IBAS comprises a configurable ETSI-standard subrack (see below) that features vertical slots to fit interchangeable slide-in units.

IBAS, Continued

Design characteristics

A cell served by an IBAS is divided into radio sectors, each addressing a number of TS. All TS in a given radio sector are served by the same Sector Processing Unit (SPU), a slide-in unit of the subrack. Traffic from all working SPU is directed to one or more of the central processing unit(s), which aggregate and switch traffic to the backbone network through their on-board physical interfaces. A wide range of Line Termination Units (LTU) extend the broad and reach of services provided by the IBAS subrack, through a number of different wireline technologies. FANT, the subrack’s detachable Fan Unit, accommodates eight fans to protect the housed electronics against overheat. A door at the bottom of the subrack hides a patch panel accommodating the connection receptacles for the fitted LTUs (if any).

The wBBMS system has a modular architecture and is composed of specific software applications / modules and commercial software packages. The software modules can be hosted in one single computer or distributed over a computer network depending on the performance requirements of the management system of a particular network.

The system consists of various hardware components such as the application server, the clients’ workstations, the DCN equipment, printers etc. In addition, one or more client workstation and printers may exist on this LAN/WAN composing the Network Management Center (NMC) of a managed network. These connections are implemented using 10 / 100BaseT Ethernet cabling.

Communication between the wBBMS and the elements of the managed network are performed via the core DCN network.

The application server is connected into the DCN using TCP/IP overEthernet 10 / 100BaseT cabling. Client workstations can be connected to the Network Management Server as well. An example of wBBMS system deployment is shown below:

wBBMS System Architecture, Continued

Operating system (OS)

At the server side (application server) wBBMS currently utilizes UNIX-Solaris2.8 OS. The graphical user interface is a JAVA-based application and runs on standard Intel-based PCs that use Windows or Linux operating system.

Database wBBMS is flexible to utilize either Oracle (standard edition) or PostgreSQL

Relational Database Management Systems.

Expandability The exact configuration of the application server depends on the network

configuration and the required number of concurrent client sessions. Due to software modularity, there is practically no limitation on the number of network elements or the number of users the system supports. System expansion is feasible by upgrading the hardware configuration, in terms of CPU power and RAM memory and by apportioning the management requirements into regional management centers (regional level management), through additional regional servers and clients.


34

Configuration Management

Introduction The Configuration Management applies monitoring, management and control changes to the network elements and to the network composed of these elements.

The main tasks of the Configuration Management include:

• Network monitoring

• Initial configuration and re-configuration of the network elements

• Adaptation to planned operational modifications / user requirements

Network presentation

Network monitoring is performed through the Tree View Window (TVW, see left picture below) where the network elements and their components are displayed in a tree structure denoting the containment relationships. Moreover, a Map View Window (MVW, see right pictures below) is available in which the elements are displayed on a map at their relative positions. By zooming in the elements, the operator can view the included components. Network elements are commissioned under wBBMS administrative domains through an SNMP-based auto-discovery process. When one element is discovered, all the contained objects (cards, interfaces, cross connections) are added to the tree view and, from now on, the network element is under wBBMS supervision.

Configuration Management, Continued

Model synchronization

wBBMS network representation is real-time in the sense that all the element attributes, held in the server, reflect the latest image of the connected elements. The model synchronization is performed through: • Trap reception and handling of trap information, if it is sufficient • Trap directed polling, in case that trap’s information is not sufficient • Configurable polling of interfaces’ status information • Continuous polling of elements’ management connectivity • On-demand synchronization

Configuration management features

Through the wBBMS Configuration module, the operator can create administrative domains, commission / decommission network elements and perform various actions on them. The main features of the Configuration Management include: • System provisioning:

- End-to-end (i.e. from a network interface to a user interface) - Subscriber-oriented (through the configuration data window of the

respective subscriber) - Flexible (through an import / export file mechanism, using an .xls file)

• Commissioning / decommissioning and control of the TS • Creation and manipulation of traffic and uplink profiles of SPU card • Configuration of radio and modem parameters • Configuration of parameters concerning BS devices or card modules • Uploading of network elements configuration files for backup purposes

on a scheduled basis. On-demand configuration restoration can be performed either at once or through scheduling

• Configuration of IP VLAN interfaces • Configuration of the ATM PVCs through the manipulation of traffic

descriptors, cross connection entries and SNCs • Software upgrade and configuration download through files for selected

network elements can be performed centrally from wBBMS. It can be performed at once or it can be scheduled to take place at low utilization hours

• Configuration of xDSL interfaces via the use of configuration and alarm profiles. Though the profile mechanism, configuration of a large number of subscriber lines (xDSL) is extremely simplified since it only requires changing values in the corresponding profile and wBBMS handles the profile downloading to every assigned line

• Massive configuration of any number of selected interfaces and devices • SPU protection mechanism • Configuration of the radio transceivers (at both BS and TS) All the aforementioned features are available to the wBBMS operator, depending on his / her privileges in the security management system.


36

Fault Management

Introduction Fault Management provides capabilities related to the notification of the

operator in the presence of faults and identification of the root cause of the fault. It provides a facility for notifying the operator in the presence of network-wide faults (Alarm Surveillance), as well as the identification of the root cause of the fault (Fault Localization).

Fault view

Fault Management main functional modules

• Historical Alarm List: The user asks for the historical alarms via an appropriate menu selection (the main window menu from the Tree View and the Element View Windows). An alarm list using filters over the various managed entities of the application (domains, elements and ports) is available to the user. The user prints the results or exports them to file

• Active Alarm List: The user is able to see the active alarms of an object by clicking the object with the mouse and making an appropriate selection or by selecting the relative menu item from the window menu, having the certain object already selected. In addition, from the window menu, the user can request the active alarms for all the objects or for a specific object or group of objects

• Real-Time Monitor Window: The time that the primary fault view is generated must not load all the existing alarms of the network. On the contrary, this window can act as a real time window alarm, which displays all the notifications (alarms and events) at the time of the occurrence from the time that this window is “running”



37

Fault Management, Continued

Fault management features

• Collection and logging of all alarms of the elements under wBBMS supervision

• Display of alarms in alarm window enabling operators to perform alarm handling

• More than one window views of the alarms (historical, active or real time) • Re-organization, filtering and sorting of alarms and their attributes • Printing or exporting of the displayed alarms in text format in order to

import them to any other application • Various actions (acknowledge, clear) on selected alarms • Assignment of different severity for each alarm type so that minor alarms

can be filtered out • Automatic update of the object’s alarm counters, per severity level,

according to an escalation mechanism based on the tree view containment

• Suspension of one network element from sending alarms when performing maintenance operations on it. Afterwards, the element can resume its normal operation and wBBMS will continue the alarm surveillance task

• Automatic suppression of several active alarms for the same interface so that only one alarm indicating the root cause (lower level) should be issued for one interface. However, all suppressed alarms are indicated by the interface’s alarms status in the corresponding window

Categorization of alarms

• Alarms related to faults on the radio links and related to loss of communication between the Base Station and the Terminal Stations

• xDSL / POTS / ISDN / SHDSL alarms: Alarms indicating fault conditions on the subscriber lines

• IMA Group - Link alarms: Alarms indicating fault conditions on the IMA Network Interface

• IP Interface Alarms • Monitoring of the status of each physical termination • Hardware alarms: Alarms indicating hardware failures of a specific

component on the network elements • QoS (Quality of Service) alarms: Alarms indicating the crossing of a

threshold defined for performance measurement • Communication alarms: Alarms indicating communication failure between

wBBMS and managed Network Elements



38

Fault Management, Continued

Lifetime and handling of alarms

When an alarm is generated, related data is stored automatically in an alarm log (database system). Alarms are available in logs for a configurable time interval. Alarms, which are older than the specified interval are removed from logs and will be stored in archives using archiving criteria set by operators. The archives can be deleted or exported in backups. When the operator double clicks on one alarm, the focus is placed on the related object that issued the alarm in the tree view. Due to this fault-tree view operational integration, the operator can identify easily the faulty component and perform all the available actions in order to detect the root cause of the problem and solve it. The user has the ability to monitor all the existing alarms according to the privileges given by the security management. Real time monitoring of the latest alarms will also be provided in order to act immediately in a fault situation.


39

Performance Management

Introduction The Performance Management ensures that the WiBAS network is operating

efficiently and that the network resources are allocated properly and effectively.

Performance management features

After the resetting of an element, the measurement process begins. As soon as the 15-min interval is completed, the current performance counter, after being copied to the intervals buffer in the element, resets and begins counting for the new 15-min interval. Up to four 15 min measurements are buffered in the element, and can be uploaded on operator’s demand. In wBBMS, the operator can request and view the performance measurements currently accumulated in the element. On-demand refresh can be employed in order to upload measurements from the element and update the current performance displayed. In addition, the operator can define a performance job for scheduled measurements uploading. After selecting any number of interfaces from several elements, the operator can schedule the performance uploading for the selected interfaces by identifying the measurement time period. On job execution, the measurements stored in the element intervals table are uploaded in wBBMS and stored in the database for operator’s data analysis. Through the wBBMS database view module, stored measurements can be filtered according to complex criteria and presented to the operator either in table format or in graphical format. Displayed data can be printed or exported to file. The reporting capabilities of wBBMS include: • Equipment and traffic utilization reports • Subscriber related statistics reports • Performance reports

Security Management

Introduction The Security Management applies access control and protects both the

network and the network management systems against: • Intentional or accidental abuse • Unauthorized access • Loss of communication To succeed in the aforementioned tasks, the Security Management offers adequate functionality for the manipulation of: • User Profiles • Access rights • User Auditing

Security management



41

Security Management, Continued

User profiles User profile management defines the application components and the

respective operations to which the user has access (e.g. severity mapping GUI, Map view, alarm table, etc.) and the sub-tree, which the user can manage. The user is not allowed to manage domains and elements other than his assigned ones neither can he / she handle alarms emitted by elements under other domains. In a sense, the geographical domain serves as an administrative domain as well. The operator makes use of the Profile Management component to define and manipulate user profiles.

Profile management

Access rights Access Rights define the operations that the user is allowed to perform on

the management tree objects. If the user cannot perform some of the operations from the set of operations supported by the object, then these operations (or attributes) will not be shown to the user at all. Access rights are defined and assigned to Security Groups. Then, users are assigned to those Groups. Using the Security Manipulation component, the operator defines and manipulates access rights for groups and assigned users.

User auditing Through a configurable user auditing mechanism, all the operator’s

configuration actions are logged. The wBBMS administrator can define configuration event logs based on several logging criteria. As soon as an action, conforming to the predefined criteria, is triggered, then the name of the user that performed the action, the time of the action, the supplied arguments and the result are written in the corresponding configuration log. The contents of the configuration logs are displayed to the administrator through the wBBMS event log module. Configuration logs can also be archived on demand.


42

CORBA Northbound Interface

Introduction The wBBMS has been developed using state of the art software tools like

CORBA, Relational Database and Java. These technologies together with the software architecture ensure the “openness” of the system and its capability to be fully incorporated into an integrated environment.

CORBA features

CORBA northbound interface is provided for integration with external OSS systems or other third party network management systems. The interface provides topology and configuration information, real time alarm propagation for fault integration and performance measurements exporting. All the information about the network elements is organized into the wBBMS information base. This is a containment tree used to represent the network being managed and is composed of a tree-organized collection of objects. Through the wBBMS northbound interface, any external system can easily traverse the information base and reach any wBBMS object, in order to acquire the required information. Additionally, SNMP based northbound interface is available, for integration with external fault management systems. Also alarms and performance measurements can be directly derived from the system database through SQL or can be exported to files. Furthermore, wBBMS can integrate any third party network elements, of relevant technology, that support standard interfaces (CORBA, SNMP etc.), delivering a common management platform for the whole underlying access network. Command line interface (CLI) is also available for manipulation of wBBMS functionality.

Radio & Modem Performance

Introduction Το attain the highest net spectrum efficiency possible, WiBAS-2X utilizes minimum overhead for transporting all types of traffic. WiBAS-2X also employs adaptive PHY modes to guarantee optimal robustness vs. performance balance, together with maximum capacity. The PHY mode that will be used depends on the environmental conditions, the interference and the RF channel, which is different for each subscriber / frame. Moving from the most robust PHY mode (4QAM 2/3 + RS) toward less robust PHY modes (e.g. 16QAM), the system switches from the highest robustness (required at poorest RF conditions) to higher efficiency (required at good RF conditions), which results in increased bandwidth. This section provides the WiBAS-2X radio and modem performance, inclusive of: • System gains (margin-less) • Sector capacity • C / N • Sensitivity • Cell ranges

Radio Frequency Planning

Introduction Radio Frequency (RF) planning is a vital procedure during dimensioning and implementation of a wireless system. Designing and planning a wireless network is an elaborate process requiring consideration of many different factors to effectively provide a robust, high performance system.

RF design considerations

• Radio characteristics (transmitted power & antenna type / gain / sensitivity) that define the system’s range

• Terrain morphology & structural environment of the area involved

• Availability of frequency channels (defined by restrictions on frequency assignment that affect system performance)

• Climatic conditions in the specific geographical area (affecting the radio propagation within the network)

• Site survey information regarding available sites for Base Station allocation, existing infrastructure, subscriber density, co-existing networks and evaluation of the environment

• Number of Base Stations (and their cell ranges) defined by the geographical area in which the desired services and applications will be delivered

• Dimensioning and final system performance objectives
