>>Telenor Hungary CEMC Project
Telenor Hungary, which is fully held by Telenor Group, ranks No.2 in the mobile telecommunication market in Hungary and has about 34% local mobile marketing shares.
Telenor Hungary has nowadays owned about 3.8 million mobile subscribers with about a 3% to 5% growth rate per year.Until now, Telenor Hungary has constructed more than 3400 base stations domestically.
Challenges to Telenor
As most of operators, Telenor Hungary is facing the same challenges:
- The existing networks are becoming more and more complex, and it is hard to guarantee network quality. The operating expenditure is increasing continuously.
- Traditional KPIs cannot properly evaluate service quality and customer experience for new services.
- User complains are increasing.
- Revenues increase slowly with a low rate of return.
By the analysis of the existing networks of Telenor Hungary, ZTE provides a CEMC solution. The CEMC-related network topology is illustrated in Figure 3.

After the CEMC system operated together with network optimization, Jiangsu Telecom’s network was improved obviously. User complaints about data service were decreased by 8%. The one-time connection success rate of IM (QQ) service was increased by 15%. The one-time connection success rate of HTTP service was increased by 11%.
Jiangsu Telecom sent the letter of commendation for project successes in Nov. 2012.
