The User Perceptions Index System for 3G Services

Abstract__The paper develops a reasonable and scientific
index system for the user perception of 3G services. By
top-down, breakdown by level method, the paper
divides the index system into 7 dimensions(service
accessibility, service retainability, service
responsitivity, ease of use, Service Integrity, Quality of
Sessions, Quality of Contents), formed by a number of
indicators. Thus, a "dimensions - indicators -
measurements" level of the index system is developed.
The paper also gives an example of mobile video
streaming service to illustrate how to make use of the
system into a certain service. The example shows that
the index system is valid and workable for user
perceptions evaluation of 3G system.
