Method of doing a broadcast service of a short message in a communication system

Abstract

This invention relates to the method of doing a broadcast service of a short message in a communication system. According to the present invention, a transmission request message of a broadcast message including the name and telephone number of an information provider is received from the information provider through a message center. The transmission request message of the broadcast message processed in the message center is transmitted from the message center to a base station and therefrom to all terminals. The terminals receive the broadcast message including the information provider's name and telephone number and displays them on the display devices of the terminals. When the terminal user wants to communicate with the information provider, the terminal performs the process for communication between the information provider and the user by using the received information provider's telephone number.

Description

BACKGROUND OF THE INVENTION[0001]The present invention relates to a method of doing a broadcast service of a short message in a communication system. Generally, in the service of a mobile communication system like CDMA, the broadcast message service provided to the subscribers is provided to the mobile terminal (or a mobile station) of said subscribers through paging channels and traffic channels. This broadcast message does not request the subscribers to answer whether or not the terminal receives the transmitted broadcast message because of its essential peculiarities.[0002]Three methods exist for transmitting the broadcast message by said paging channels. First, a multi-slot broadcast transmission method sends the broadcast message to all slots of a control channel to send the broadcast message by using all the mobile terminals that are located in the service area of a base station. This is the simple and fast method having no time delay in the message. However, this method gives...

Benefits of technology

The present invention provides a method for easily communicating with information providers through a broadcast message system. The method uses two subparameters, a third party call name and a third party call number, to insert the name and telephone number of the information provider in the broadcast message. The terminal user can easily store this information in their address directory for future use. The method allows the terminal user to easily communicate with the information provider and establish a traffic channel with them. This results in a more convenient and efficient communication system.

Problems solved by technology

However, this method gives a large load to the control channel and makes the process of the other message impossible.

Second, if the user wants to confirm the information of the received broadcast message, the user must memorize the previously displayed telephone number.

Third, because of the above two inconvenient processes, the quality and efficiency of the broadcast service of the originally planned short message can decrease.
