It is a common phenomenon that college students are equipped with mobile phones when they live collectively in school. Mobile phones have become an important tool for college students to communicate with foreign countries and an important part of college life. So what are the important effects of the increasing diversification of mobile phone functions on college students? This paper will analyze this.

First, the communication function of mobile phone expands the communication space of college students.

Communication scholar McLuhan said that the media is an extension of people. The calling and short message functions of mobile phones are extensions of people's mouths and ears. Through the medium of mobile phone, people can communicate thousands of miles apart, which is an extended interpersonal communication. College students live a collective life. They come from all parts of the motherland, study in schools, and stay away from their relatives and friends. They can tell their parents about their study life at school, their recent ideological trends, or seek help in their study life by calling or texting. It is understood that talking with parents is an important part of college students' weekly life. Chatting with classmates from other schools, sending short messages, and getting to know each other's college life can also expand the communication space. Communicating with people is the actual needs of people in every society. The expansion of communication space makes the social characteristics of college students appear, thus eliminating the bad psychological feelings such as loneliness.

The normal management of students in schools also relies more and more on the call and SMS functions of mobile phones. The number of students each counselor takes varies from one hundred to several hundred. Counselors often contact the monitor with the help of mobile phones when informing students of something. He calls the monitor first, and then the monitor informs his classmates, or sends a mass notification to each classmate's mobile phone in the form of short messages through the function of Fetion. The expansion of mobile phone functions has brought great convenience to counselors' daily work, which can make every student receive the notice in time, accurately and fairly, avoiding the indirectness of the monitor's notice or the particularity that someone is absent when notifying. Schools should also build a short message exchange platform. By establishing a short message communication platform in schools, you can enjoy mental health consultation and various educational information, school information, work notices and other resources through short messages, and establish a communication platform for timely communication between teachers and students. ①

During the Chinese New Year, communication, telephone messages and blessings between students are also conducive to enhancing the feelings between students. Graduates should leave accurate mobile phone numbers on their resumes when looking for jobs, and they can use employers to communicate with graduates in time. Students can also get to know the global news information, master the latest global information and broaden their horizons through the media mobile phone newspaper.

Second, the Internet access function of mobile phones meets the information needs of college students.

Information demand is the natural demand of people in every society. People living in society have the characteristics of group demand, isolation and poor information, which are non-social. Information can eliminate the uncertainty of people. There is a theory of "use and satisfaction" in communication. The study of "use and satisfaction" regards the audience as individuals with specific needs, and regards their media contact activities as the process of "using" media based on the motivation of specific needs, so that these needs can be "satisfied". Newspapers, radio and television media report a lot of current affairs news every day, which makes people know what is happening in the world and can eliminate the uncertainty of people's information. Mobile phones access the Internet, integrating information, and making the mobile phones that people carry with them become the terminals for accessing the Internet. Compared with computers, mobile phones have the advantages of small size, portability and low price, and mobile phones have the advantages of surfing the Internet compared with computers. These advantages make more and more people use mobile phones to surf the Internet. (3) Meet people's information needs quickly and timely. Mobile phones are widely used by college students. Mobile phone information carrier is more convenient and direct than newspaper, radio and TV information carrier in information transmission. Especially the 3G mobile phone, its powerful online function is equivalent to a mobile intelligent computer.

Internet access on mobile phones can make them grasp the dynamic news happening around the world more timely and conveniently. At the same time, college students can enjoy other functions brought by surfing the Internet, such as reading novels, sharing blogs and forums.

Thirdly, the mobile phone is a "double-edged sword", and college students should make good use of it to serve themselves.

Mobile phone is a communication tool and information receiving tool. Its tool characteristics determine that it is a "double-edged sword", and there is no difference between good and bad. Mainly depends on how people who use it use its positive role to serve themselves. In reality, many students have infinitely expanded the QQ chat function, Internet surfing function, game function and MP3 function of mobile phones, and some students who send short messages in class are not listening carefully and addicted to the entertainment function of mobile phones. Even if you fail in the exam, your study will be affected. Some students also cheat by using mobile phone short messages, which greatly reduces the integrity image of college students.
