Embodiment Construction

[0040] FIG. 3 shows a configuration diagram of a first preferred embodiment of a multimedia call control system in a mobile communication system according to the present invention. Fig. 4 shows a multimedia call connection protocol in a mobile communication system according to the first preferred embodiment of the multimedia call control system.

[0041] As shown in Fig. 3 and Fig. 4, the multimedia call control system includes: mobile station (for example: sending mobile station) MS1 201, utilize the multimedia call service option to initiate a multimedia call and perform multimedia communication according to the multimedia call initiated; BS / BSC 202, For identifying the multimedia call service option of MS1 201 as a multimedia call bypass option; MSC 203; and mobile station MS2 204 (e.g. receiving mobile station), wherein in said multimedia bypass service option, BS / BSC 202 is directly connected MS1 201 and MS2 204 without going through the interworking function IWF or the p...

Abstract

The present invention discloses systems and methods control a multimedia call / service in a communication system between mobile stations that exist in the same network. A method of controlling the multimedia call can initiate a radio call in a mobile station, recognize a multimedia call service option transmitted from the mobile station, set up the radio call via a base station where the receiving mobile station is located by using the multimedia call service option and the receiving telephone number, confirm in the receiving mobile station and notify a receiving user. The multimedia call between the originating / receiving stations is set up after the radio call. Therefore, the systems and method according to the invention can process the multimedia call only through a base station and a mobile switching center without passing through an inter-working module or a packet data serving node in the mobile communication system.

Description

technical field [0001] The present invention relates to a terminal in a mobile communication system, and more particularly, to a system and method for controlling multimedia calls in a mobile communication system. Background technique [0002] Mobile terminals for providing voice services are very common. Due to the reduced cost of information and communication equipment, the use of portable computers (PCs) has rapidly spread. Therefore, the mobile communication system now receives a wireless data service request for accessing a mobile phone network by using a mobile terminal and a portable, and then performs a communication function between them. [0003] Such a mobile communication system establishes a data call between visual terminals through an inter-working function (IWF) or a public data service node (PDSN) for modem analog or packet network access. In other words, the video terminal in the mobile communication system performs call processing according to the data s...
