The present invention relates to a call quality analysis method using GPS information in a mobile communication network.

As is well known, technology in the field of information and communication has recently evolved into a multimedia (Multimeadia) convergence of voice communication technology and technology for transmitting / receiving images, texts, data, etc., by simply breaking existing services related to voice information. . The development of the information and communication field plays an indispensable role in advancing into a high information society, and has grown into a key industry that determines national competitiveness.

In particular, among the information and telecommunications sectors, the mobile telecommunications service industry best reflects these characteristics. Currently, the mobile telecommunications service market is increasing in size, and fierce competition is inevitable. However, this fierce competition started with the controversy of call quality of mobile communication terminals, and now competition is gradually intensified by advertising and price competition, and now the competition of mobile communication providers is accelerating until development of various value-added services. .
