The user perceptions index system for 3G services

The paper develops a reasonable and scientific index system for the user perception of 3 G 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 3 G system.
