Recent growth of ring-tone and ring-back-tone download market as the derived market of cellular phone yields the new trend in music consumption from listening to display. This means that consumer purchase the ring-tone and RBT not for his appreciation but for counterpart's consumption, in a word, conspicuous consumption. Study aims at questions on whether cellular phone user can perceive the ring-tone and RBT's brand personality and how they express their self-image via ring-tone and RBT. Survey was administered for 196 college students who is dominant purchase group of market segment. Hypotheses are such as : congruity of self image and brand personality of ring-tone and RBT. Through the T-test, findings said that user's extrovert self image are not led to ring-tone's extrovert brand personality and user's introvert self image are not led to introvert ring-tone's brand personality of ringtone. same result was applicable to RTB. Cellular phone user's purchase behavior are different from those of product and service.

Two experiments were carried out in order to investigate the influence of Ring-Back-Tone(RBT) music on the evaluation of the phone-call receiver's personality in dimensions of Openness, Extroversion, and Neuroticism. In a preliminary experiment, the subjects listened to 17 RBT music stimuli in random order and assessed the personality associated with liking for each music using the 12 personality traits(N=15). Among the 17 RBTs, three were selected to be used in main experiment and they were distinguished from each other in terms of the tree personality dimensions(p<0.001). In main Experiment, it was hypothesized that the evaluation of phone-call receivers' personalities would be influenced by the personality of RBT music. Therefore, in the main experiment, the subjects were divided into four groups and each listened to one of the three RBTs or to a plain ringing tone(control group) until the receiver(the experimenter) answered the call. After interviewing the receiver, subjects evaluated her personality using the 12 traits. The empirical results provide evidence that the RBT influences the judgment of phone-call receiver's personality in terms of the three personality dimensions(p<0.001), supporting the hypothesis. In addition, it is found that there is a positive correlation between the personalities of RBT music and the phone-call receivers' personalities elaborating the affirmative result for the hypothesis(r=0.753, openness, p<0.01, r=0.753, extroversion, p<0.01; r=0.265, neuroticism).

In this paper, we implement PAMD(Positive Answering Machine Detection) for discrimination human and ARS. We are used Grunt detection, Glitch Noise detection and Tone detection for PAMD. It distinguishes voice signals from ring-back tone and glitch noise respectively. And as a second step, it judges whether human responses or ARS responses after integrating pattern changes like initial response period, the number of voice data, each time of voice data period and glitch noise. The accuracy is about 9375 in ASR and about 98％ in Mobile phone.

The purpose of the study is to investigate the influence of Ring-Back-Tone(RBT) music on the evaluation of the phone-call receiver's personality in dimensions of Openness, Extroversion, and Neuroticism. In a preliminary test, the subjects listened to 17 RBT music stimuli in random order and assessed the personality associated with liking for each music(N=15). Among the 17 RBTs, three were selected to be used in Experiments I and II and they were distinguished from each other in terms of the three personality dimensions(p<0.001). In Experiment I, the subjects were divided into four groups and were asked to make a call to interview an unknown receiver(N=60). Different RBT music was installed depending on the group to which each subject belonged. It was found that different RBT influences the caller's evaluation of the receiver's personality, supporting Hypothesis 1(p<0.001). Moreover, the ratings of the receiver's were highly correlated with those of the RBT music stimuli in terms of Openness(r=0.722, p<0.001) and Extroversion(r=0.753, p<0.001). In Experiment II, an identical experiment design was applied for a new group of subjects who were acquainted with the receiver(N=40). It was hypothesized that previous knowledge about a person would weaken the RBT effect. The results showed that RBT exerted no effect on the evaluation of the receiver's personality when the caller knew the receiver. It was also found that 12 personality traits, where each of the three personality dimensions is described by four traits, facilitated assessment of the character of the RBT music as well as the personality of the receiver.

Recently a mobile service is changing into a system environment that offers the customer various contents service. Representative example of service is a Calling Identity Del ivory Service(CID). Such service has the problem in the case which the receiver cannot remember the phone number of the sender; it has a difficult problem that cannot easily confirm whose the phone number it is. Therefore, it is desirable to design and implement visual services that can enhance the recognition of users. In this paper, we propose the architecture that is similar to a Calling Identity Delivery Service. We propose the architecture for communication service and system that is able to visually display the information of the sender using 2D image data in mobile environment. After that we set the image information to represent the user and this method is able to visually display the information of the sender by transmitting an image data through channels from switch station or base station using the server. When the receiver receives a phone call from the sender, this method provides an efficient service by transmitting visual data with bell sound. That is, the image information of sender is appeared on liquid crystal display(LCD) of the receiver at the same time. We investigate the concepts for processing real-time transmission of image data and describe an example of the implementation result that is based on system. This technology has a potential influence on the marketing and presents an efficiency of this method.
