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:
