Abstract

This invention relates to a device and a method for setting up IP connection by circuit connection, which combines IP phones with PSTN phones to dial PSTN phone numbers to set up circuit connection transmitting IP addresses for setting up IP connection so as to set up IP connection.

Description

A kind of connection by circuit set up the apparatus and method that IP connects

Affiliated technical field

The utility model relates to a kind of IP phone terminal that is used for and sets up the method that IP connects.

Background technology

Conventional telephone terminal is to utilize the PSTN net to set up circuit to connect, and carries out Speech Communication.The IP phone terminal is to utilize IP network to set up IP to connect, and carries out Speech Communication.

IP establishment of connection, the most direct method are to rely on the IP address of call terminal to set up the IP connection.When IP address of terminal was dynamic assignment, because the calling party does not know callee's IP address, it was very inconvenient to utilize the IP address to connect.

At present, known method is to identify an IP phone terminal with a character string, needs another as the equipment of server, identification strings can be resolved to the IP address, call terminal must connect exchange for information about with this server, could set up conversation and connect.This just need to have the people that this communication system is runed, and safeguards.Required cost is finally from being to collect from end user location.And the configuration of terminal is to general user's inconvenience.

Also having a kind of method is to adopt the terminal of P2P technology, SKYPE for example, Www.skype.comAlthough connecting to set up in the P2P network not to need an autonomous device to do server.In order to accomplish marking terminal in network, the user need to set earlier the information such as username and password, uses inconvenient.Need these user profile of maintenance management server.And the P2P network needs a large amount of users to keep network, can't set up otherwise connect.

A kind of IP phone is arranged now, integrate with the traditional PSTN phone.Both had the PSTN interface, can carry out PSTN Netcom words, had the IP interface again, can carry out the IP network conversation.But it only is the simple combination of the two, carries out PSTN conversation and carry out the IP conversation that it doesn't matter mutually.When using IP phone, the user still can feel the inconvenience in setting, dialing.

Summary of the invention

Need server, need operation in order to overcome existing IP connection foundation, user's configuration, awkward deficiency, the utility model provides a kind of the connection by circuit to set up the apparatus and method that IP connects, and makes user's experience and traditional landline telephone identical.

The technical scheme that its technical problem that solves the utility model adopts is: traditional PSTN phone and IP phone are integrated, obtain the IP address information of IP phone with a functional module, the IP address information is become audio-frequency information, this signal is sent by the circuit connection.From circuit connects, obtain audio-frequency information with a functional module, parse IP address wherein, connect thereby set up IP.The method that the IP address information is become audio-frequency information can be the dtmf signal that produces the digit strings of IP address correspondence.The method of resolving IP address in the audio-frequency information can be the dtmf signal of resolving wherein.The method that produces and resolve dtmf signal can be to generate and detection chip with special-purpose DTMF, also can use relevant DSP, processes with corresponding Digital Signal Processing software.

The beneficial effects of the utility model are, the user dials traditional telephone number, and system sets up IP automatically and connects, thereby carry out IP communication.Not reliance server and operation, user's experience and black phone are identical.

Do not have

Embodiment

Once concrete communication operation process: the calling party initiates once conversation, with the pstn telephone number of pstn telephone elder generation call peer, callee's ring, off-hook, sets up circuit and connects.The calling party sends the IP address information after circuit connects foundation, the callee receives and parses, and callee's IP phone is initiated the IP connection request to the calling party, and calling party's response is set up IP and connected.Both sides' phone automaticallyes switch and enters the IP conversation, cuts off simultaneously PSTN and connects.

Claims

1. one kind connects by circuit and to set up the apparatus and method that IP connects, having simultaneously IP network connects to be connected such as PSTN with the circuit interconnection network and connects, it is characterized in that: set up earlier circuit and connect, to connect transmission at circuit for the identification information of setting up the IP connection such as IP address, and set up then IP and connect.

2. device according to claim 1 is characterized in that: finish set up the identification information that IP connects such as turn to the IP address and audio-frequency information between mutual conversion.

3. device according to claim 1 is characterized in that: dial common pstn telephone number and just can set up the IP connection.
