The communication system of＜employing dual-channels communication terminal 〉

With reference to accompanying drawing 3, provided the communication system that adopts according to dual-channels communication terminal of the present invention.

This communication system has two kinds of implementations, and a kind of is symmetrical Terminal communication system, and another kind is asymmetric Terminal communication system.

The logical valve system of symmetry terminal

As shown in Figure 3, symmetrical Terminal communication system comprises calling party's dual-channels communication terminal 1, callee's dual-channels communication terminal 1, communication network 3, broadband IP communication network 4 and binary channels telecommunication/data network server 2.

In Fig. 3, calling party's dual-channels communication terminal 1, by communication network 3 and broadband IP communication network 4, and binary channels telecommunication/data network server 2, set up with callee's dual-channels communication terminal 1 between communicate by letter.

With reference to accompanying drawing 3, can realize the communication of called dual-channels communication terminal is initiated by telephone communication network according to dual-channels communication terminal of the present invention.In general, as the terminal equipment of broadband IP communication network, the dual-channels communication terminal disconnects with the broadband IP communication network when not communicating by letter.In order to carry out broadband connections, the equipment access band IP communication network that needs communicating pair, caller dual-channels communication terminal is access band IP communication network initiatively, and called dual-channels communication terminal is by in the called control information of transmitting of telephone communication network, know and oneself need carry out broadband connections, thereby start broadband access.Behind the dual-channels communication terminal access band IP communication network at first with oneself the IP address and telephone number at binary channels telecommunication/data network server registration, registration content has comprised contents such as whether online IP address, telephone number, current broadband connection at least, the calling party can be at the state of binary channels telecommunication/data network server lookup called number corresponding equipment, be whether broadband connection is online, and obtain online callee's IP address.Behind the IP address that obtains the callee, the calling party can directly pass through IP communication call callee by the IP broadband network, sets up the IP communication channel, realizes needed broadband connections.

Communication system of the present invention is worked in the following manner.

When calling party's dual-channels communication terminal was prepared to initiate communication, the user was with plain old telephone part 100 off-hooks of calling party's dual-channels communication terminal 1, and the use telephone keypad is dialled the plain old telephone part 100 of being callee's binary channels terminal 1.When putting through callee's binary channels terminal 1, callee user's off-hook, both sides set up voice call by communication network 3 and connect.At this moment, send the IP communication request signal by calling party's plain old telephone part 100 to callee's terminal, the core control section 500 of callee's terminal receives this signal, and send the confirmation signal that succeeds in registration to calling party's terminal, and the core control section 500 of calling party's terminal receives this signal.At this moment, the key control unit 500 of calling party and callee's terminal starts their IP data communications part 300 respectively.IP data communications part 300 is called out and is connected IP network, inserts the Internet.Behind calling party and the callee's dual-channels communication terminal 1 access band IP communication network 4, their IP data communications parts 300 separately respectively with they the IP address and telephone number in binary channels telecommunication/data network server 2 registration, registration content has comprised contents such as whether online IP address, telephone number, current broadband connection at least.After registration was finished, binary channels telecommunication/data network server 2 kept the online dual-channels communication end message of current registration in database, and sent the confirmation signal that succeeds in registration to the calling party who registers and callee's dual-channels communication terminal 1.These information can be for other dual-channels communication terminal or the inquiry of other types communication terminal.

There is a problem to occur, calling party and callee may successively finish registration, and the opposing party's of registration relevant information was not finished in direct inquiry after a side finished registration, can the inquiry less than, cause the system failure, therefore, provided the solution that solves the problem that calling party and callee successively succeed in registration below.

After receiving the confirmation signal that succeeds in registration, the key control unit 500 of calling party and callee's dual-channels communication terminal 1 all reads the precalculated position in the memory module 304, if this precalculated position is empty, the confirmation signal that then this succeeded in registration is recorded on this precalculated position.And the key control unit 500 of calling party and callee's dual-channels communication terminal 1 all passes through plain old telephone part 100 and sends network successful connection signal to the other side's dual-channels communication terminal 1, enters wait state subsequently.

When calling party and callee's key control unit 500 receives network successful connection signal from the other side, read in precalculated position to memory module 304, if this position is empty, then with this signal record on this precalculated position, and enter wait state.

Note, the very important point is,, all this precalculated position to be emptied in empty and receiving and succeed in registration confirmation signal and detect memory module 304 in the precalculated position that receives network successful connection signal and detect memory module 304 in empty.So that later operation can be carried out.This is very important for adopting the fast dual-channels communication terminal of network connection speed as active connection side's execution mode, and also is very important to the situation that has taken place to go offline after successful connection first.

According to one embodiment of the present invention, calling party's kernel control module 500 is according to dialing and testing circuit 204 is detected when the calling party dials that dialing status arranged, and the calling party is defined as initiatively connection side.And therefore callee's key control unit 500 is defined as passive connection side with it owing to there is not the testing result of dialing.
