The present invention relates to a wireless communication terminal having a broadcast channel information updating function and a method thereof. More particularly, the present invention relates to a broadcast channel information providing server through a wireless Internet and requests broadcast channel information in a current region. The present invention relates to a wireless communication terminal having a broadcast channel information update function and a method for updating existing broadcast channel information by receiving corresponding broadcast channel information from the broadcast channel information providing server.

In the present invention, the wireless communication terminal is a mobile communication terminal, a personal communication service (PCS) terminal, a personal digital assistant (PDA), a smart phone, a next generation mobile communication (IMT-2000) terminal, a wireless LAN terminal and the like through wireless communication, A portable wireless communication terminal capable of transmitting / receiving text and image data, etc., refers to a wireless communication terminal having a TV (TeleVision) broadcasting and a radio broadcasting reception function.

In addition, the broadcast in one embodiment of the present invention includes a TV (TV) broadcast, radio broadcast and the like.

In general, the wireless Internet is intended to provide Internet services in current wireless communication networks. Early wireless Internets include Handheld Device Transport Protocol (HDTP) and Handheld Device Markup Language (HDML) from Nokia and the Nokia TTML (Tagged Text Mark-up) from Unwired Planet (now Phone.com). Language and Ericsson's Intelligent Terminal Transfer Protocol (ITTP) have been used in telecommunication networks within subsidiaries, but they have not been widely used due to inconsistencies in the protocols for wireless Internets used by each company.

To secure this, in June 1997, four global telecommunications companies, Ericsson, Motorola, Nokia, and Unwired Planet, decided to establish a common standard. In June 1999, more than 100 companies from around the world participated, and LG Information & Communication, Samsung Electronics and SK Telecom participated in Korea.

The Swap Protocol Architecture (Wap Protocol Stack) proposed by the Swap Forum consists of WSP (Wireless Session Protocol), WTP (Wireless Transaction Protocol), WTLS (Wireless Transport Layer Security), WDP (Wireless Datagram Protocol), etc. The function is as follows.

WSP defines the equivalent of HyperText Transfer Protocol (HTTP) /1.1, which defines sessions for long-term use, provides a suspend / resume function for session management, and can negotiate protocol functions. Let's do it.

WTP provides transactional data transfer, reliable and unreliable transfers, and retransmissions for error recovery.

WTLS is a kind of security protocol based on the Transport Layer Security (TLS) of the Internet, and provides security services such as authentication, non-repudiation, integrity, and confidentiality.

WDP provides port addressing for end-to-end transmission and is responsible for transmission functions such as the Internet's User Datagram Protocol (UDP).

On the other hand, in order to use such a wireless Internet, a wireless communication terminal must have a wireless internet platform (browser). A browser is an application that lets you see all the information on the World Wide Web.

Currently, the wireless Internet platform standards adopted by Korea are WIPI developed by Korean companies and BREW developed by Qualcomm.

On the other hand, there may be various advantages of the wireless communication terminal, but above all, it can be said that the greatest advantage in the mobility provided to the user to call. Due to this mobility, the number of wireless communication subscribers has increased exponentially, and in recent years, wireless communication terminals are widely used by the general public.

However, as time goes by, the merits of mobility have gradually disappeared to users of wireless communication terminals, and a multifunctional wireless communication terminal capable of providing more various additional services is required.

Accordingly, most recently released wireless communication terminals have a camera function, a radio broadcast reception function, a TV (TV) reception function, a music (for example, MP3: MPEG layer 3) playback function, acupressure function, and blood glucose detection function. And various additional functions such as an ultrasonic imaging function. In particular, the radio broadcast reception function and the TV broadcast reception function are one of the new features.

With the support of the broadcast receiving function (radio, TV), users can watch (or listen to) the broadcast anytime, anywhere using a wireless communication terminal, and can acquire new information quickly.

Here, referring to the conventional broadcast channel setting method, the conventional broadcast channel setting technique requires the user to search for a broadcast channel and set it as an audible channel in order to watch or listen to a desired TV broadcast or a radio broadcast.

Therefore, in order to receive a broadcast when a user moves out of a residential area in which a provisional audio channel is set, and moves to another region, a user must search for a broadcasting channel again and set an audible channel. There was an inconvenience.

The present invention has been proposed to solve the above problems, by accessing the broadcast channel information providing server through the wireless Internet to request the broadcast channel information in the current region, the broadcast channel information corresponding to the region to provide the broadcast channel information It is an object of the present invention to provide a wireless communication terminal having a broadcast channel information update function and a method thereof so that a user can easily watch or listen to a broadcast at any time in any region by updating existing broadcast channel information received from a server. .
