The Difficulties Faced By The Network Operation and Maintenance

High OPEXOMC

“Why my call drop

again?”

“In some places we can not go to test”

Can not reflect and resolve network problems in time

“Performance analysis reports

don’t come out yet”

“What reason? KPI information, log,

so much information is really a

needle in a haystack!”

Time-consuming while handing customer complaints

Difficult

massive data analysis

Collection of user call information and stored in the database. Analyze data, proactively identify network problems, improve network performance

and customer satisfaction based on MR and associated log information. Reducing OPEX by automatic tools to enhance the efficiency of the operation and

MR Vs CDT

From Macro to Micro

MR CDT

Macro Date

All the measurements reports collection.

Key MR datas acquisition and analysis of associated users, associated call and events.

Micro Data

Focus on the macro statistics of the concern network performance of coverage and evaluation of the interference.

Concerned about the detailed analysis of a single call event and user's actual call perception.

Determine whether the event is caused by the user or by wireless network side.

Accurately reappear the call environments of the customer complaints

Analyze the whole network performance and find the poor performance cells

NetMAX Final Target ：Minimize drive test, becoming the first choice for wireless network optimization for fault analysis and positioning.

Topic Analysis ： Interference Analysis

Handover failure impaction on user perception

Single handover failure

Continuous handover failure

Call Drop due to handover failure Find continuous handover failure occurred in cell 208-31-3 from NetMAX tool

Through the associated call list,all the

handovers to cell 31-3 are failed while

other handovers are normal.

*Case Study:China Mobile,Hunan

The target cell signal is very strong while switching to the target cell every time ,therefore the handover process itself has no problem.

Through the detail of handover, the uplink power level detected is very low or can’t be received and don’t match the strong downlink signal detected from the phone

Old museum cell 3 is subjected to the same frequency interference from new WCB site through the base station and frequency distribution map, resulting in continuous unreasonable handover failure.

Problems will be located and solved quickly by

NetMAX . Change WCB site frequency point from512 to 514 and problem has been solved.

difference between the serving cell and neighbor cells,

and form a matrix listJudge the relation between cells, and generate a

Highlights of the NetMAX

NetMAX

Reducing the Cost of OPEX 7*24Hours Continuous Data Collection

Simple Deployment Configurable Application

Overall solutions enable remote maintenance supporting possible;

Reducing drive test and the corresponding cost expenses;

Strong data processing function, can greatly improve the efficiency of the network optimization, which can save manpower cost.

• The independent processing boards are used to handle d data acquisition which reduce the load of main processing boards of controller.

• Support 7*24 hours continuous data collection so that users’ complaints can been traced in advance.

BSC/RNC finishes data acquisition through the TCP/IP network and send data to NetMAX Server by file .

The operator can choose to put data in a centralized server or some distribution servers.

Configurate different Strategy and parameters for different network scenes.

Client management terminals can be accessed through TCP/IP network and users can operate NetMAX system in remote mode.

UniPOS Application 1-Hong Kong CSL UMTS2.1G/900M Network Migration

Customer Evaluation

“After the CSL network cutover, the network KPIs surpass those of the original NSN’s network; both voice and data network have better KPIs; particularly the PS network KPIs become the benchmark in Hong Kong, which makes me very proud.”

CSLCSL is the largest carrier in Hong Kong with 3milli users and GSM 900/1800M, UMTS900M/2100M networks. It’s holding is Telstra.

The challenge CSL FacingThe old complex network is provided by NSN and can’t meet the requirement of new service, especially the indoor coverage system. The resource usage ratio is low with high OPEX.Therefore CSL decides to swap the network by ZTE.

Customer Benefits from ZTE Network

Optimization Service

Average throughput rises to be 2 to 3 times of

other Hong Kong carrier

High voice service quality

End to end delay is decreased and user

experience is improved greatly.
