In recent years, the telecommunications have used the concept of NPS (Net Promoter Score) for customer relationship management, but there is neither definite theory research nor instructive instance research. However, this paper summarizes an approach with instance case analysis to improve customer loyalty via NPS data mining, which has extensive and practical significance for tele-companies. First,...
The rate satisfaction of government and corporate customers, to which telecom companies pay special attention, is an important part of the overall satisfaction of the market segment. Focusing on specialline products and based on interview with experts and literature review, this article builds an effect model comprising four factors affecting the major government and corporate customers’ satisfaction...
As the protocol conformance testing has become a common phase during the development process, the TD_LTE wireless terminal tester must be designed in accordance with the protocol specifications. For this purpose, special programming languages, such as TTCN-3, as well as tools are available. This paper builds the corresponding test system based on the standard testing notation TTCN-3, and elaborates...
Protocol conformance testing is a very important step in implementation of protocols. The EMM protocol describes the function for EPS mobility management, so it is indispensable for the development of TD-LTE protocol stack. In the implementation and development phase of TD-LTE terminal tester, it must be used in order to tally with the protocol specification. In this article, a method based on Telelogic...
This paper introduces and analyzes the LTE RRC sub-layer protocol stack structure and function, designs the state and the state conversion process of the RRC sub-layer. It also designs the realization of the RRC connection establishment process. And we simplify signaling interaction between layers based on the characteristics of the project. Finally, it designs the simulation of SDL flowchart of the...
