Abstract

The invention is suitable for the field of mobile communications, and provides a video telephone method, a device and a 3G mobile terminal. The method comprises the following steps: when one party or both parties of the video conversation do not access in the 3G network, the two parties are switched to a TCP/IP mode to carry out the video conversation. In the invention, when the called party or the calling party does not access in the 3G network, the video telephone mode is switched to the TCP/IP mode, so that the 3G mobile terminal can also realize the video telephone when not under the 3G network coverage.

Description

A kind of video telephone method, device and 3G portable terminal

Technical field

The invention belongs to moving communicating field, relate in particular to a kind of video telephone method, device and 3G portable terminal.

Background technology

Along with popularizing of 3G network, visual telephone can be accepted by increasing people and use, but because network coverage problem, the 3G portable terminal not necessarily can reside in 3G network all the time.At this moment, if the side that communicates by letter is in 2G network following time, the user can not carry out visual telephone, brings inconvenience to the user.

Summary of the invention

The purpose of the embodiment of the invention is to provide a kind of video telephone method, is intended to solve existing 3G portable terminal not in 3G network following time, and the user can not carry out the problem of visual telephone.

The embodiment of the invention is achieved in that a kind of video telephone method, and described method comprises the steps:

As video calling one side or both sides not during resident 3G network, both sides switch to and carry out video calling under the TCP/IP pattern.

Another purpose of the embodiment of the invention is to provide a kind of videophone devices, and described device comprises:

Video calling is initiated the unit, is used to initiate the 3G network video calling;

The call mode converting unit is used for video calling one side or both sides not during resident 3G network, with the video calling mode switch under the TCP/IP pattern; And

TCP/IP video calling unit is used for carrying out video calling under the TCP/IP pattern.

Another purpose of the embodiment of the invention is to provide a kind of 3G portable terminal that comprises above-mentioned videophone devices.

The embodiment of the invention not during resident 3G network, switches to TCP/IP pattern with video telephone mode callee or calling party, makes the 3G portable terminal not cover following time at 3G network, also can realize visual telephone.

Concrete Implementation Modes

In order to make purpose of the present invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.

In embodiments of the present invention, when caller or called not resident 3G network, both sides switch under the TCP/IP pattern and communicate by letter, and realize visual telephone under the TCP/IP pattern.

In the embodiment of the invention, according to the network coverage situation of 3G network, the caller, called party has following four kinds of communication patterns:

1, all resident 3G network of calling and called both sides;

2, the resident 3G network of caller, called resident 2G network;

3, the resident 2G network of caller, called resident 3G network;

4, caller and called resident 2G network.

When all resident 3G network of calling and called both sides, it is just passable to carry out visual telephone according to normal video phone handling process in the 3G network.

Fig. 1 shows the resident 3G network of caller that the embodiment of the invention provides, the visual telephone flow process of called resident 2G network, and details are as follows:

1. video telephone mode is initiated in caller, calls out called;

2. caller receives network release notice, and is former because called not resident 3G network requires caller to return back to voice call;

3. caller is dialled up on the telephone;

4. caller is dialled up on the telephone and is obtained local ip address after the success, sends to called by note or other patterns information such as local ip address and calling number;

5. caller enters and waits for called responsive state, and wait timeout is then got back to initial condition;

6. after the called call request that receives caller, the record calling number;

7. called dialling up on the telephone;

8. behind the called success access network that dials up on the telephone, the visual telephone communication mode is switched to the TCP/IP pattern;

9. the called monitored call state that enters;

10. called transmission call comprises information such as called IP address, serve port to caller in the call information;

11. after caller receives called response, the visual telephone communication mode is switched to the TCP/IP pattern;

12. caller is called by the TCP/IP call by pattern;

13. the called calling that receives, answer successfully after, both sides carry out visual telephone.

Fig. 2 shows the resident 2G network of caller that the embodiment of the invention provides, the visual telephone flow process of called resident 3G network, and details are as follows:

1. after local resident 2G network is judged in caller, dial up on the telephone;

2. caller is dialled up on the telephone and is obtained local ip address after the success, sends to called by note or other patterns information such as local ip address and calling number;

3. caller enters and waits for called responsive state, and wait timeout is then got back to initial condition;

4. after the called call request that receives caller, the record calling number;

5. called dialling up on the telephone;

6. behind the called success access network that dials up on the telephone, the visual telephone communication mode is switched to the TCP/IP pattern;

7. the called monitored call state that enters;

8. called transmission call comprises information such as called IP address, serve port to caller in the call information;

9. after caller receives called response, called by the TCP/IP call by pattern;

10. the called calling that receives, answer successfully after, both sides carry out visual telephone.

When caller and called all resident 2G network, the visual telephone flow process when the resident 2G network of both sides' visual telephone flow process and caller, called resident 3G network is identical, repeats no more.

Fig. 3 shows the structure of the videophone devices that the embodiment of the invention provides, and for convenience of explanation, only shows the part relevant with the embodiment of the invention.

This videophone devices can be used for the various 3G portable terminals that possess visual telephone function, it can be the software unit that runs in these communication terminals, also can be used as independently, suspension member is integrated in these communication terminals or runs in the application system of these communication terminals, wherein:

Video calling is initiated unit 31 and is initiated the 3G network video calling.

Call mode converting unit 32 is video calling one side or both sides not during resident 3G network, with the video calling mode switch under the TCP/IP pattern.

Wherein, the module that dials up on the telephone 321 connects network by the mode of dialling up on the telephone, and obtains local ip address information.

Call information sending module 322 sends to local ip address and calling number called when making a call.

Call module 323 sends call to the other side, and with local ip address information, call number information, perhaps serve port information sends to the other side.

TCP/IP video calling unit 33 carries out video calling under the TCP/IP pattern.

The above only is preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of being done within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
