Embodiment 1

[0063] Two mobile terminals are directly connected through the I / O communication interface for multimedia communication. The specific method is:

[0064] establishing a connection between the input / output communication interface of the calling side mobile terminal and the input / output communication interface of the called side mobile terminal;

[0065] The mobile terminal on the calling side and the mobile terminal on the called side sequentially pass through the local multimedia communication protocol stack module, data buffer controller module, input / output communication interface adapter module and input / output communication interface respectively, and send multimedia communication through the established connection The data is sent to the opposite end; and the mobile terminal on the calling side and the mobile terminal on the called side respectively pass through the established connection, sequentially through the local input / output communication interface, input / output c...

Embodiment 2

[0102] The two mobile terminals are connected through the I / O communication interface of the gateway to perform multimedia communication. The specific method is:

[0103] Establishing a serial connection between the input / output communication interface of the mobile terminal on the calling side, the input / output communication interface of the gateway, and the input / output communication interface of the mobile terminal on the called side;

[0104] The mobile terminal on the calling side and the mobile terminal on the called side sequentially pass through the local multimedia communication protocol stack module, data buffer controller module, input / output communication interface adapter module and input / output communication interface respectively, and send multimedia communication through the established connection The data is sent to the opposite end; and the mobile terminal on the calling side and the mobile terminal on the called side respectively pass through the established...

Embodiment 3

[0110] A mobile terminal and a multimedia terminal conduct multimedia communication through the gateway. Specifically divided into two situations:

[0111] Situation 1: the calling party is a mobile terminal, and the called party is a multimedia terminal of another system.

[0112] The specific method is: establishing the input / output communication interface of the calling side mobile terminal, the input / output communication interface of the gateway and the serial connection between the gateway and the called side multimedia terminal;

[0113] The mobile terminal on the calling side passes through the local multimedia communication protocol stack module, data buffer controller module, input / output communication interface adapter module and input / output communication interface in turn, and sends multimedia communication data to the gateway through the established connection, and then the gateway Convert the data into the protocol format supported by the multimedia terminal on ...

Abstract

The invention relates to a mobile terminal, comprising a call establishing module, a multimedia communication protocol stack module, an input / output (I / O) communication port adapter module, a channel controller module and a data buffer controller module, and the multimedia communication is realized through the I / O communication port of the mobile terminal. The invention further discloses a method for establishing multimedia communication linkage between mobile terminal and a corresponding communication system. By adopting the mobile terminal provided by the invention, the property of the I / O communication port of the mobile terminal can be fully utilized, and reliable video and multimedia communication linkage can be established between the terminals or between the terminal and a gateway under the situation that an operator network support cannot be acquired.

Description

technical field [0001] The invention relates to wireless communication, in particular to a method for establishing a multimedia communication connection between mobile terminals, a mobile terminal with corresponding functions and a communication system composed of it. Background technique [0002] Mobile terminals realize multimedia communication, such as video calls and other video services are important service components in 3G mobile terminals. Currently, the 3G-324M (also known as H.324M) standard of 3GPP is adopted as the 3G terminal video call specification. [0003] By default, 3G-324M terminals run on the Circuit Switched (CS) network. The main connections of 3G-324M terminals in the CS network are as follows: [0004] 1. Call Set-up between two 3G terminals based on the H.324M standard; [0005] 2. A call establishment between a 3G terminal based on the H.324M standard and a PSTN multimedia terminal; [0006] 3. A call establishment between a 3G terminal based on ...
