Description

A method for receiving and transmitting of a memo message in a mobile communication system}

The present invention relates to a text information service of a mobile communication system, and a terminal in a mobile communication system for transmitting and receiving, displaying and storing a memo message such as a phone number and a schedule between a terminal and a terminal or between a terminal and an information providing center. It relates to a method of receiving and transmitting a memo message.

In general, the mobile communication is a variety of vehicles and mobile phones, radio calls, mobile payphones and frequency employment communication, and is widely used in the field of ships and aviation as well as personal communication.

Such mobile communication uses a multiple access method to efficiently use the limited communication resources of the time and frequency bands, and frequency division multiple access (FDMA) and time division multiple access depending on how the user uses communication resources. It is divided into TDMA and Code Division Multiple Access (CDMA).

In the case of digital mobile communication in our country, the code division multiple access (CDMA) method is adopted and used. The CDMA mobile communication system is a spread spectrum communication method, in which one frequency is divided into a plurality of channels through a code. It is a system where users can communicate with the same frequency.

In the mobile communication system, the channel of the forward link from the base station to the terminal is composed of a pilot panel, a synchronization channel, a call channel, and a call channel. In this case, the call channel transmits text information from the base station to the terminal through a message, wherein an important message includes additional information and terminal call functions for all terminals in the service area. In addition, a call channel connects a terminal and a system called by a call channel to enable a phone call.

In such a mobile communication system, the additional information transmission service is transmitted by using both channels of a call channel and a call channel. The call channel transmits a call and other additional information together in addition to a short message, thus limiting the length of a short message that can be transmitted. In the case of a long short message which cannot be transmitted on the call channel, it is transmitted to the terminal through the call channel.

In other words, when a center providing a short message transmission service transmits news information and announcements to terminals, a short channel is transmitted by sequentially establishing a call path through each terminal and a communication channel.

However, in such a conventional mobile communication system, the text information service could transmit only limited information to the terminal user who receives the service from the center that provided the service, and the terminal user received message information such as a phone number and a schedule on his terminal. Could not be sent to the message center, and there was a problem that the terminal users could not exchange message information with each other.

The present invention has been made to solve the above problems, the technical problem of the present invention, regardless of the type or manufacturer of a mobile terminal, the terminal user can upload and download the message information from the center that provides the service The present invention provides a method of receiving and transmitting a memo message of a terminal in a mobile communication system capable of storing transmitted information and transmitting and storing message information between terminal users.
