Mobile networks are experiencing a revolution of broadband access and IP transmission. Broadband access results in the personalization of end

users and the diversication of services; IP transmission causes services to be deeply packaged, posing a challenge to in-depth service analysis.

In the process of network reform and evolution, due to the personalization of users and diversication of services, there are different quality

requirements on different users' different services, one user's different services, and the same service of different users, thereby posing an

unprecedented challenge to operators' operation and maintenance. No longer does maintenance focus on single pieces of network equipment,

nor is network optimization oriented merely towards single network element KPI. Rather, it is necessary to pay attention to QoE and KQI

according to users' requirements on KQI and the requirements of services on network quality.

In this about-face process, how do we make QoE and KQI visual and assessable? How do we quickly spot and address QoE and KQI problems?

How do we manage QoE and KQI like network element KPI? SmartCare solution gives you a complete answer.

How to Conduct Overall KQI

Management

Broadband access subverts the single

service model of voice service in traditional

mobile communication networks, making

the diversication of application possible.

The widespread use of broadband access

to mobile networks frees the last segment

of traditional broadband networks from the

constraint of lines. Therefore, high-speed

mobile networks deliver richer application

than xed broadband networks. Mobile

Web browsing, mobile online games,mobile video, mobile search and mobile mail

have gradually found application in mobile

broadband-based networks.

Along with changes in the services carried in

the networks, operators face the challenge

of turning from voice KQI management

to overall quality management of multiple

services. Voice services are not very

demanding on network quality; the key to

ensure accessibility, retention, and portability.

With the diversication of services, different

services have different requirements on

quality: Web services are not very demandingon overall rate, but require low latency from

click to display; online games require low

latency in full-service time; mobile videos

demand low bit error (one-time transfer

accuracy), etc. Mobile networks provide

increasingly rich services, which have more

and complex requirements on quality. In

network operation and maintenance, overall

KQI management poses a huge challenge to

operators.

How to Quickly Locate KQI Problems

Overall QoE and KQI management addresses

the establishment of a monitoring system,

which makes KQI visual, and an evaluation

system, which makes KQI problems visual.

On the basis of overall QoE and KQI

management, how to quickly locate KQI

problems becomes a second challenge

posed by the evolution of mobile networks

to operators. At present, there are two

barriers to the quick location of KQI

problems – E2E multiple equipment vendors

caused by a long business chain, and deep

service packaging brought about by IPtransmission. Only when the two barriers are

effectively removed, can the quick location

of KQI problems become possible.

How to Conduct Differentiated QoE

Management

The diversication of services carried on

mobile networks brings about opportunities

and challenges for differentiated QoE

management. QoE differentiation means

high-end users can be developed on thebasis of traditional user model to enlarge

operators' sources of revenue, while value-

added services have not yielded in large

amounts of prots. At the same time,

however, QoE differentiation will pose a

great challenge to operators' operation and

maintenance capability – How to conduct

differentiated QoE management? How to

improve high-end customers' KQI while

ensure general users' basic KQI? How to

restrict the uncontrolled occupation of

network resources by malicious users? All

these are issues that urgently need to be

addressed.

How to Conduct Delicacy KQI

Management

The widespread use of broadband has

beefed up mobile networks' capacity, and

promoted the development of more and

more high-quality services. Meanwhile,

network loads grow along with users'

demand. However, as operators gain

revenue mainly by leasing their networks,their revenue has not increased along with

load. While bringing about opportunities for

operators, broadband-based networks got

operators into a contradiction of increased

volume without increased revenue. How

to balance cost, revenue and QoE/KQI is

a question that must be considered by all

mobile operators that are undergoing the

high speed process.

Along with the widespread use of high-

speed Internet access and the diversication

of application, network loads are directly
