The present invention relates to a wireless communication terminal having a function of receiving over-the-air broadcasting and broadcast streaming data, and a method thereof. More particularly, the present invention relates to a broadcast streaming data providing server as receiving strength of the over-the-air broadcasting decreases. The present invention relates to a wireless communication terminal having an over-the-air broadcasting and broadcast streaming data receiving function for receiving broadcast streaming data, and a method thereof.

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 airwave broadcasting in the present invention includes terrestrial analog / digital and digital multimedia broadcasting (DMB) type TV (TV) broadcasting and radio broadcasting, satellite DMB type TV (TV) broadcasting and radio broadcasting.

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 over-the-air broadcast receiving function (radio, TV), users can watch (or listen to) the broadcast anywhere in the non-visual field using a wireless communication terminal, so that new information can be obtained more quickly. It became.

However, the conventional wireless communication terminal having the above-mentioned airwave broadcasting reception function has a problem in that it cannot smoothly receive the airwave broadcasting when entering the astigmatism zone.
