Description

PERSONAL TELECOMMUNICATION SUPPORTING SYSTEM CAPABLE OF PROVIDING OPTIMIZED INTERNET SERVICE IN VARIOUS TELECOMMUNICATION NETWORK ENVIRONMENT AND PERSONAL TELECOMMUNICATION CLIENT USING THE SAME}

The present invention provides a personal communication support system for supporting efficient use of on-line services on the Internet according to characteristics of various communication networks and various personal communication terminals such as a public switched telephone network, a mobile communication network, a satellite network, and an individual for using the same. It relates to a communication client.

With the development of computer technology, the Internet users have become more convenient and the number of Internet users is increasing rapidly. With the increase of Internet users, various kinds of on-line services are developing on the Internet. Methods of using on-line services on the Internet typically use a personal computer with communication capabilities. In addition, a mobile phone can be connected to a PDA (Personal Digital Assistant) or a portable computer using a serial interface to wirelessly use on-line services on the Internet. However, the use of on-line services on the Internet wirelessly is known to be inadequate for on-the-go or normal business due to the characteristics of the wireless communication network.

Recently, a communication service capable of using an on-line service on the Internet with only a mobile communication terminal such as a mobile phone has been provided. The WAP (Wireless Application Protocol) is used as a protocol to facilitate the retrieval of Internet information in a wireless communication environment. According to the wireless communication network, a mobile communication terminal uses a WML (Wireless Markup Language) format to express information. On-line service is provided. However, the transmission characteristics of the mobile communication network and the operating system of the terminal are different for each terminal manufacturer, and the mobile communication operators use their own WAP proxy server, and the terminal manufacturer manufactures the terminal according to the corresponding WAP proxy server. On-line services currently provided through mobile communication networks on the Internet are relatively simplified on-line services that provide simple text information or notify e-mail reception to a mobile communication terminal.

Mobile telephones using a mobile communication network use a circuit-type connection establishment method such as Point-to-Point Protocol (PPP). Therefore, it is known that it is difficult to receive on-line services on the Internet normally while moving because it is necessary to wait for at least 4-5 seconds to establish a new connection whenever a handover occurs, which is a characteristic of mobile communication. This problem is known to be difficult to overcome as long as the circuit-type connection establishment method is used. To overcome this problem, a packet type channel for data-only service is expected to be introduced in a digital mobile communication network.

However, even in the packet type channel, due to resource limitations, the transmission bandwidth provided to the mobile communication terminal may be limited, and the effective transmission rate delivered to the mobile communication terminal may be lowered according to the traffic conditions. As a result, it is expected that different transmission bandwidths will be provided for each communication network, and accordingly, effective transmission rates will also be different and various types of communication terminals will exist according to the user's work type. And there will continue to be low speed network environments such as current public pay networks, portable telephone networks and satellite networks.

The on-line service environment on the Internet is changing to a more sophisticated and diverse form of the multimedia environment on the premise that the network can be continuously expanded and supported. When using on-line services on the Internet, a user spends a lot of time obtaining additional information such as advertisements or logos, rather than necessary information. Therefore, Internet users spend a lot of time to get the information they need when using on-line services on the Internet, including complex configurations and large amounts of additional information, or limited on-line services provided for low-speed networks. -Information should be used only for line service.

Terminals for using the Internet exist in various forms, from personal computers to wireless portable telephones, and even if each has its own protocol, the maximum speed is limited depending on the traffic. Therefore, in such a communication service environment, it may not be efficient to define and apply a uniform protocol in a batch. Therefore, it is necessary to apply an appropriate transport layer protocol according to the characteristics of the communication network and the terminal.

Accordingly, an object of the present invention is to solve the above-mentioned problems, and to provide a personal communication support system for optimizing and providing data provided from a plurality of content providers according to transmission characteristics of a communication network and characteristics of a communication terminal, and using the same. To provide a personal communication client for.
