Description

A voice call system based on the network telephone system

【Technical field】

The invention relates to a voice communication system in the technical field of communication, in particular to a voice communication system based on a network telephone system.

【Background technique】

With the development of real-time messaging software (IM, Instant Messenger, that is, software such as Yahoo! Messenger, GOOGLETALK, QQ, MSN or ICQ), in addition to pure real-time text communication, it has also developed into voice communication, especially Skype, which uses peer-to-peer (p2p), is developing most rapidly.

Although this type of Internet phone has the advantages of free and better communication quality, the actual use of the group is still limited to Internet users, and it is still very difficult for people who only know how to use traditional phones to use Internet calls. Therefore, in the development of Internet telephony, how to let people who are not good at using computers and networks can also make good use of the benefits brought by Internet telephony.

Traditionally, most of the integration of traditional telephone and Internet telephone systems has not separated from the computer and operated the computer, that is, the telephone is only connected to the computer through the USB interface, and simple operation of the computer is still required to answer or make a call. Another kind of IP network phone, although it can be used like a normal phone, it can only be used to talk to the same IP network phone, and cannot be integrated into any network phone system, such as calling a Skype user.

In order to allow Internet phones and traditional analog phone devices to communicate with each other, the Skype out function has been developed in the Skype system, which transfers to the desired analog phone through the existing analog phone system. However, this conversion method requires the cooperation of fixed-line telecom operators, and the call voice must pass through the fixed-line telecom equipment and lines to be transferred to the analog telephone device, so that a certain fee must be paid to the fixed-line operator. The cost will naturally be borne by the user. Regardless of whether Skype out is charged or not, it is still impossible for Skype users to make calls from traditional analog phone devices to Internet calls.

Because the traditional analog telephone device only provides number keys, there is no way to input English and Chinese Internet phone account numbers like a computer. Therefore, if the traditional analog telephone device needs to be able to communicate with the Internet phone, this problem must be solved first.

In order to completely avoid the use of the fixed network, and to allow the Internet phone and the analog phone to communicate with each other, a patent "Internet phone conversion box" has been proposed in the prior art of the Republic of China Patent Publication No. M284155. In this prior art, the conversion between the telephone number and the Internet phone code is mainly used. In addition to overcoming the problem that the analog phone can only press numbers, it can also be used to completely communicate through the Internet phone system.

However, in this prior art, the comparison table between the phone number and the Internet phone code is stored in the local end (that is, the office or home at the same location as the phone device), and the corresponding data cannot be shared smoothly. Furthermore, such prior art cannot be applied if the analog telephone device is a telephone extension connected to a Private Automatic Branch exchange (PABX).

Generally speaking, even if an enterprise has applied for as many as 10 calling lines, its publicized phone number has only one as a representative. Connect online (in fact, I am afraid that there is a problem with the connection). However, if these 10 lines are all busy at the same time, the entire telephone system is easily paralyzed because the prior art lacks a relative processing mechanism.

【Detailed ways】

Please refer to FIG. 1 , which is a schematic view of the voice communication system based on the network telephone system of the present invention. As shown in Figure 1, the voice communication system based on the Internet telephone system of the present invention mainly utilizes the existing Internet telephone system 10 (such as Skype) or the digital voice transmission means developed by itself, no matter which way (wired) Or through WiMax/Wifi 11's wireless network telephone device (i.e. the mobile Internet device 12a, Internet device 12b that executes the client program), or the analog telephone device 14a~14c that enters through the communication intermediary device 18, It is necessary to register and obtain the Internet phone device A10a, the Internet phone device B10b, and the Internet phone device C10c respectively in the Internet phone system 10, and complete the procedure of logging into the Internet phone system 10 before calling each other.

The mobile internet device 12a and the internet device 12b executing the client program of the VoIP system 10 can receive calls and/or make voice calls to their VoIP accounts A and B to which they belong. That is to say, the Internet access device 12b can call the Internet phone account A10a through the Internet phone account B10b in the Internet phone system 10 .

For the analog phone device 14a, it has an independent Internet phone account. The analog telephone devices 14b～14c all belong to the telephone extensions connected to the private automatic branch exchange 16 (Private Automatic Branch exchange, PABX) and have extension numbers, so will share the relative network telephone of the switchboard representative number that the private automatic branch exchange 16 (PABX) has account, but the private branch exchange 16 (PABX) still has a plurality of communication channels as a general switch for the use of the analog telephone devices 14b-14c.

The above-mentioned communication intermediary device 18 can actually be a server-level computer, so it will also execute the client program of the Internet phone system 10, so as to log in to the Internet phone system 10 as shown in Figure 1, just to achieve the present invention The technical features of the client program must be wrapped in a package, and the flow of the voice originally played from the speaker is changed to be forwarded to the components in the communication intermediary device 18 of the present invention.

In the voice communication system based on the Internet phone system of the present invention, there are three different communication modes in total, that is, for example, the analog phone device 14b or 14a calls the Internet phone device 12a, and the Internet phone device 12b To call the analog telephone device 14b or 14a, as shown in FIG. 8 , the analog telephone device 14a calls the analog telephone device 14d through the Internet telephone system 10, so the three communication modes will be described below as examples.

Please refer to FIG. 2 . FIG. 2 is a schematic diagram of the first embodiment of the voice communication system based on the network telephone system of the present invention. As shown in FIG. 2 , in the voice call system based on the VoIP system of the present invention, the communication intermediary device 18 mainly includes an analog/digital signal conversion module 20, a conversion module 22, and a VoIP module 24, and is electrically connected to The analog telephone device 14a is indirectly connected to the analog telephone devices 14b, 14c. Among them, the Internet phone module 24 is the client program of the above-mentioned Internet phone system 10 . As shown in Figure 2, if the analog telephone device 14a attempts to call the Internet telephone device of the Internet device 12a, since the user has already known the virtual phone number of the Internet device 12a in advance, the user can directly dial the virtual phone number of the Internet device 12a as if dialing a traditional phone. Press the virtual phone number on the number keys of the telephone device. When the analog/digital signal conversion module 20 in the communication intermediary device 18 receives the virtual phone number, it will convert the phone number dialed by the analog phone device 14a into a digital signal. Then, the conversion module 22 converts the phone number of the digital signal into the corresponding Internet phone account A according to the data from the external main control device 30 (as shown in FIG. 3 ) or the built-in storage unit. Finally, use the VoIP module 24 to call the VoIP device corresponding to the VoIP account (that is, the Internet device 12a) through the VoIP system 10, so that the analog telephone device 14a and the VoIP device (that is, the Internet device 12a) conduct a voice call. If there is any response or call voice from the Internet phone system 10, the analog/digital signal conversion module 20 converts it into an analog signal and then transmits it to the analog phone device 14a.

As shown in Figure 2, if the analog telephone device 14b tries to call the Internet telephone device of the Internet access device 12a, since the analog telephone device 14b belongs to the telephone extension connected to the private automatic branch exchange 16 (Private Automatic Branch exchange, PABX), although the user has The virtual phone number of the Internet access device 12a is known in advance, but the user still has to press "*9" first, as in dialing an outside line, and use multiple lines between the private branch exchange 16 (PABX) and the communication intermediary device 18. One of the communication channels, and then press this virtual phone number on the number keys of the telephone device. Similarly, when the analog/digital signal conversion module 20 in the communication intermediary device 18 receives the virtual phone number, it will convert the phone number dialed by the analog phone device 14b into a digital signal. Then, the conversion module 22 converts the phone number of the digital signal into the corresponding Internet phone account A according to the data from the external main control device 30 (as shown in FIG. 3 ) or the built-in storage unit. Finally, use the VoIP module 24 to call the VoIP device corresponding to the VoIP account (that is, the Internet device 12a) through the VoIP system 10, so that the analog telephone device 14b and the VoIP device (that is, the Internet device 12a) perform voice calls. If there is any response or call voice from the Internet phone system 10, the analog/digital signal conversion module 20 converts it into an analog signal, and then transmits it to the analog phone device 14b.

Please refer to FIGS. 3A-3B, which are schematic views of the second embodiment of the voice communication system based on the VoIP system of the present invention. As shown in Fig. 3A, in the voice communication system based on the VoIP system of the present invention, in addition to the VoIP system 10 shown in Fig. 1, Internet access device 12a, Internet access device 12b, communication intermediary device 18, analog In addition to the telephone devices 14 a - 14 c , the Internet phone device A10 a , the Internet phone device B10 b , the Internet phone device C10 c , and the private branch exchange 16 (PABX), a main control device 30 is additionally included.

In the voice communication system based on the network telephone system of the present invention, the main control device 30 can mainly handle whether the plurality of communication channels between the private branch exchange 16 (PABX) and the communication intermediary device 18 are all busy or have Free lines are available, and it is also possible to centrally manage all telephone numbers or switchboard representative numbers (belonging to the private branch exchange (PABX) 16) corresponding to the corresponding data of the corresponding Internet phone account. As shown in FIG. 3B , in the voice communication system based on the VoIP system of the present invention, the main control device 30 mainly includes a status database 38 , an update module 36 , a corresponding database 34 , a provision module 32 , and a verification module 40 . However, the main control device 30 can only provide the function corresponding to the data, so it can only include the corresponding database 34 and the providing module 32 . If the main control device 30 only provides the usage status of a plurality of communication channels, only the status database 38 and the update module 36 may be included.

When centrally managing the corresponding data of all phone numbers or switchboard representative numbers corresponding to the Internet phone account, the providing module in the main control device 30 will find out the corresponding Internet phone account from the corresponding database 34 according to the phone number from the conversion module 22 , and reply to the conversion module 22. A plurality of pieces of corresponding data are stored in the corresponding database 34 , and each corresponding data corresponds to a phone number corresponding to an Internet phone account. It should be noted that after the conversion module 22 obtains the corresponding Internet phone account from the providing module 32 according to the phone number, it can store the corresponding relationship between the phone number and the Internet phone account in the storage medium of the communication intermediary device 18, so that The conversion module 22 can directly convert the phone number into a corresponding Internet phone account. In this way, in addition to completing the above conversion work more quickly, it is also possible to prevent the user from completing the dialing request according to the old corresponding data when the corresponding data cannot be successfully obtained from the main control device 30 .

When dealing with the plurality of communication channels between the private branch exchange 16 (PABX) and the communication intermediary device 18, whether they are all busy or have free lines for use, it is necessary to first collect the usage status of the plurality of communication channels. In order to collect the usage status, the update module 36 will change the usage status of the switchboard representative numbers corresponding to the communication channels in the status database 38 according to the notification from the communication intermediary device 18 . In the plurality of status data stored in the status database 38, each status data corresponds to the use status of the communication channels with the representative number of the switchboard, and the use status can be roughly divided into busy line and empty line.

The notification of the above-mentioned communication intermediary device 18 can be, the dialing or hanging up notification of the analog telephone device 14a ~ 14c sent by the analog/digital signal conversion module 20 and/or the network telephone module 24 (like a general telephone, both sides of the conversation can first Hang up the phone, so the hang up notification may come from one of the two parties on the call), or the conversion module 22 is searching for the corresponding Internet phone account according to the phone number. In this way, when the use states of these communication channels are all busy, if there are analog telephone devices 14a-14c that need to make a call, the main control device 30 will reply to the communication intermediary device 18, and the analog telephone devices 14a-14c All the dialings to be made are busy, so the dialing service cannot be provided for the time being, so as not to be stuck here or even crash like the conventional technology. When a user hangs up the phone, so that one of the usage states of the communication channels is empty, the main control device 30 will reply to the communication intermediary device 18, and the dialing that the analog telephone devices 14a-14c intend to perform is In the empty line, and at the same time reply the corresponding Internet phone account as mentioned above, so that the communication intermediary device 18 connects the calls of the analog phone devices 14a-14c.

Before the providing module 32 finds out the corresponding VoIP account according to the phone number or switchboard representative number, it needs to confirm whether it is the phone number or the switchboard representative number (if the switchboard representative number, there will be company name data) according to the corresponding data in the corresponding database 34 ). If it is a phone number belonging to the analog phone device 14a, the providing module 32 can directly reply to the corresponding Internet phone account. If the extension phone like the analog telephone device 14b needs to confirm whether there is a free line first, so it is impossible to directly reply to the corresponding Internet phone account number, it is necessary to check whether there is a free line first.

In addition, since the number of communication intermediary devices 18 may be very large, a transceiver interface (not shown) can be added to the main control device 30 and the communication intermediary device 18 to strengthen the communication processing between the main control device 30 and the communication intermediary device 18 ability. Multitasking is preferably used between the transceiver interface and the communication intermediary device 18 . In order to ensure the smooth operation of the system, avoid unexpected reasons (such as crashes or failure to receive previously sent verification packets) to occupy valuable communication channels (existing between the private branch exchange 16 (PABX) and the communication intermediary device 18), the main The verification module 40 in the control device 30 can check whether these communication channels are still in normal use when they are found to exceed the predetermined time and are still in busy lines from the usage status of these communication channels in the status database 38.

In addition to the above functions, the main control device can also provide relevant information and processing modes about the full line. Please refer to FIG. 4 . FIG. 4 is a schematic diagram of the master control device of the present invention. As shown in FIG. 4 , the main control device 30 of the present invention further includes a full line module 44 , a full line database 42 , and a frequently full line module 46 .

The full line module 44 can be based on the status data in the state database 34 as shown in the 3B figure, query the use status of the communication channels corresponding to the switchboard representative number, if they are all busy lines, then update the full line The full-line notification corresponding to the representative number of the switchboard in the database 42. A plurality of full-line records stored in the full-line database 42, each full-line record corresponds to a full-line notification corresponding to the switchboard representative number. The frequent full line module 46 is based on these full line records in the full line database 42, and queries the corresponding full line notification of the representative number of the switchboard.

In this way, the system personnel can appropriately increase the communication channel between the private branch exchange 16 (PABX) and the communication intermediary device 18 according to the frequent full-line notification, that is, increase the Internet telephony program in the communication intermediary device 18, increase The number of connection ports of the communication intermediary device 18 and the private branch exchange 16 (PABX). Please refer to FIG. 5, which is a schematic diagram of the registration procedure of the present invention. As shown in FIG. 5 , in order to add, delete, and modify corresponding data in the corresponding database 34 shown in FIG. 3B , the communication intermediary device 18 further includes a registration module 60 , and the main control device 30 further includes an update module 64 .

When the VoIP module 24 is installed in the communication intermediary device 18, the registration procedure can be performed at the same time. Before or after completing the installation of the Internet phone module 24, the system operator can use the registration interface 62 to fill in the registration data (including at least one of the phone number and the representative number of the switchboard, and the corresponding Internet phone account number, or include the company name), and wait until After the user completes and sends the registration data, the registration module 60 can collect the registration data and transmit it to the update module 64 of the main control device 30 , and then the update module 64 can update the corresponding data in the corresponding database 34 .
