Description

1246266 V. Description of the Invention (1) Field of the Invention The present invention relates to a device and method for implementing a wireless short message service (SMS) based on a fixed network, and more particularly to a wireless telephone device for implementing wireless communication through an existing fixed network. Device and method for SMS service. [Knowledge technology] In recent years, due to the considerable progress in the integration of data and voice communications, the analog voice signals have been digitized in the digital environment, and are therefore quite easy to integrate with digital data. Digital communication standards have many built-in data transmission functions. Take the GSM (Global System for Mobile Communications) standard as an example. The short message service (SMS) is an example. Newsletter competition; through the convenience and the user can just publish. The same. Using ‘as the polling election is the SMS service. As the business and services can communicate with the wireless paging system, the SMS service sends textual information. The use of the SMS service requires the receiver on the keyboard of the mobile phone. The recipient will receive this letter. At present, the SMS service is also a tool for reading information, sports results, and services provided by Tianwu Smart Network (IN The beginning of other value-added services of Intel's IP-based network, and the death of traditional fax market competition. 'Compared to paging and fax, the method is very simple. The mobile phone enters the message to be sent and then sends the information.' Just like receiving an e-mail saying that all aspects of daily life should be widely used, such as receiving the latest stock market information, gas, and traffic conditions, etc., one of the goals. Ligent Networks' active development of roads has grown rapidly, and it has opened many Media 'provides users with a variety of convenient and fast services 1246266 V. Invention Description (2). Telecommunications companies in advanced countries such as Europe and the United States have successively developed the IN function in recent years to provide the public with unprecedented and more convenient communication services. Users also use IP networks. Can realize the function of the above-mentioned short message service. It can be known from the above two known technologies that the user terminal has not yet been able to effectively utilize the fixed network (Fixed Network) to implement the SMS service through the Public Switched Telephone Network (psTN). How to make use of the existing fixed telecommunication network to bring more convenient services to users ’is unnecessary to repeat the process of setting up to use resources more effectively, which is an urgent issue.
