Embodiment Construction

[0029] Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. In the following description, for clarity and conciseness, structures and functions known in the art are not described in detail.

[0030] Fig. 2 is a diagram showing a mobile communication network used for a video phone according to the present invention.

[0031] Referring to Figure 2, the circuit-switched mobile communication network includes Node Bs (202 and 252) used as base stations, Radio Access Networks (RAN) (204 and 254) (they are the base station subsystems of Node B), and a mobile service switching center (MSC) / visited location register (VLR) (206 and 256) (corresponding to the core network of the circuit switched domain), home location register (HLR) (208 and 258), and gateway MSC (210 and 260). The MSC manages call control and movement of user terminals. The VLR and HLR provide functions for registering and managing user terminal data.

Abstract

Provided are a method and an apparatus for video telephony in a mobile communication terminal. According to the method, when a calling mobile communication terminal attempts video telephony, call connection between the calling mobile communication terminal and a called mobile communication terminal is made. The calling mobile communication terminal checks whether video telephony profile data of the called mobile communication terminal has been registered. When the video telephony profile data of the called mobile communication terminal has been registered, the calling mobile communication terminal selects the video telephony profile data and transmits the profile data to the called mobile communication terminal to form a video telephony channel.

Description

[0001] Cross-references to related applications [0002] This application claims the priority of the application filed in the Korean Patent Office on August 24, 2006 and assigned Application No. 2006-80260, the content of which is incorporated herein by reference. Technical field [0003] The present invention generally relates to a method and device for video telephony (VT) in a mobile communication terminal, and more particularly to a method and device for supporting fast video phone connection in a mobile communication terminal. Background technique [0004] With the installation of multiple functions in mobile communication terminals, such as color displays, mass storage, digital cameras, wireless Internet platforms, multiple chord audio output, MPEG layer 3 (MP3) functions, and video on demand (VOD) functions , It becomes possible to provide a variety of multimedia services such as video telephony services. 2.5G and 3G wireless networks, such as Wideband Code Division Multipl...
