Embodiment
Below in conjunction with drawings and Examples, the present invention is described in further detail.
As shown in Figure 1, the present invention utilizes home gateway and smart mobile phone to realize the system of cordless telephone, comprises family gateway equipment and smart mobile phone, both is computer equipment, and by IP network communication.Described family gateway equipment comprises the voice call module, and smart mobile phone comprises the voice terminal module, and the voice call module controls is connected on the phone on the home gateway phone port, and by IP network, with telecommunication server, communicates by letter; The voice terminal module is responsible for mutual with the user, and as telephone key-press, answer or call, show that caller ID, ring back tone play, the voice terminal module is completed telephone connection alternately by IP network and voice call module.
The present invention utilizes home gateway and smart mobile phone to realize the method for cordless telephone, and after family gateway equipment was opened, its voice call module was intercepted the order on IP network always, and described order comprises the request of telecommunication server transmission, the order that smart mobile phone sends.The user first will be on smart mobile phone, IP address, communication port, authentication information and the terminal number of input family gateway equipment.Then the voice terminal module by IP network, sends the voice call module of log-in command to family gateway equipment, and log-in command comprises authentication information, and authentication information is the character string of the regular length calculated by cryptographic algorithm (as MD5).After the voice call module is received log-in command, authentication information is carried out verification,, if incorrect, directly abandon this log-in command; If correct, the voice call module records sends IP address, port and the terminal number of log-in command.
The present invention utilizes home gateway and smart mobile phone to realize the method for cordless telephone, comprises that the user makes a call and two kinds of situations of new phone incoming call are arranged.
As shown in Figure 2, be the flow chart that the user makes a call, concrete steps are as follows:
When S101. as the user, inputting telephone number making a call on smart mobile phone, its voice terminal module sends call command to the voice call module by IP network, this order comprises authentication information, terminal number, telephone number, speech coding form, and local terminal receives IP address, the port of voice packet.
S102. after the voice call module of family gateway equipment is received this call command, by IP network and telecommunication server, call out to set up alternately.
S103. when opposite end received calls, telecommunication server transmission opposite end received order to the voice call module, and opposite end receives in order IP address, the port that carries speech coding form, opposite end reception voice packet.
S104. the voice call module, by IP network, sends bind command to the voice terminal module that sends this call command, and bind command comprises authentication information, terminal number, speech coding form, and opposite end receives IP address, the port of voice packet.
S105. after the voice terminal module is received bind command, beginning is packed speech coding according to the speech coding form, and by IP network, sends voice packet to the IP address that receives voice packet and the opposite end of port, receives simultaneously the voice packet that send opposite end, and after decoding, by microphone, play.
S106. during user's terminated call, the voice terminal module sends the voice call module of ON-and OFF-command to family gateway equipment by IP network, and stops coding, decoding, transmission, the reception of voice packet, and ON-and OFF-command comprises authentication information, terminal number.
S107. after the voice call module is passed through the ON-and OFF-command authentication, by IP network and the mutual terminated call of telecommunication server, so far a talk-through.
As shown in Figure 3,, for the flow chart of new phone incoming call is arranged, the steps include:
S201. when the phone of home gateway phone port connection is called out in opposite end, this phone ringing of voice call module controls, and by IP network, sending call command to all voice terminal modules of registering, call command comprises IP address, the port of authentication information, terminal number, telephone number, speech coding form, opposite end reception voice packet.
S202. after the voice terminal module receives that call command and authentication are passed through, by sound and image mode prompting user, the phone incoming call is arranged.
S203. user key-press incoming call answering, the voice terminal module sends bind command to the voice call module by IP network, and bind command comprises authentication information, terminal number, speech coding form, and local terminal receives IP address, the port of voice packet.After the voice call module was received bind command, sending ON-and OFF-command did not have the voice terminal module of incoming call answering to other.The voice terminal module of incoming call answering starts according to the speech coding form, speech coding is packed, and send voice packet by IP network and receive IP address and the port of voice packet to opposite end, receive simultaneously the voice packet that opposite end sends over, and play by microphone after decoding.
S204. when the terminated call of opposite end, the voice call module sends ON-and OFF-command to the voice terminal module that receives calls, and ON-and OFF-command comprises authentication information, terminal number.
S205. after the voice terminal module is received ON-and OFF-command, stop coding, decoding, transmission, the reception of voice packet, so far a talk-through.
The present invention is not limited to above-mentioned execution mode, for those skilled in the art, under the premise without departing from the principles of the invention, can also make some improvements and modifications, within these improvements and modifications also are considered as protection scope of the present invention.The content that is not described in detail in this specification belongs to the known prior art of this area professional and technical personnel.
