WiMAX operability SOLUTION

Release 1,Marko Siiskonen / BBW, WiMAX





Operability solution

• Architecture• OMS

• NetAct





Could this be Nokia’s operating service center

for 15 WiMAX networks around the world ?





Nokia WiMAX operability solution

• Overall system level centralized management solution instead of Box management

• Advanced NW planning solution (as in Nokia WCDMA RAN)• High efficient network management

• Fast BTS plug and play adoption to network

• No configuration work on the BTS site

• Mass operations

• To change parameter by configuration plan, manage software to 100s of NE by couple of mouse clicks

etc…

• Very scalable Operability solution (40…10ks base stations)

• High Re-usage of Nokia current Operability sub-solutions (NetAct and network elements)

brings more reliability

• Same operability architecture as used in Nokia WCDMA RAN.

• Same operability network management system product as used in Nokia WCDMA, GSM, etc…

• Support for DSL world monitoring systems (alarms & statistics)





• BTS and ASN GW

• Network element specific elementmanager (EM) functionality

• Connection to OMS

• Operation & Maintain Server (OMS)• Centralizes and mediates O&M traffic

• Basic alarm monitoring and PM reporting.

• Interface for Nokia and 3rd party NMS

• NetAct• Centralized management for Nokia and

non Nokia network elements

• North Bound interface for global managementcluster

Nokia NetAct Traffica





Real-time traffic monitoring and analysis tool

Nokia NetAct TrafficaFocusing on users and service usage

• Traffica focuses on live traffic

and subscriber activity

• Traffica provides real-time visibility over the

end-users activity and service usage, in the whole network

or down to cell level

• For example, Traffica will show you…

• how much subscribers are using the services,

at what time, from where in the network,

what problems they have

• the details of calls and other activities,

for each subscriber

•the usage and problems per mobile type

• the activity of user groups, roamers vs. home subscribers,

corporate customers, etc.

for multi-technology,multi-vendor

networks
