Description

Voice E-mail Transceiving Method

The present invention relates to a method for transmitting and receiving voice e-mail, and in particular, a voice e-mail for receiving Internet voice e-mail (PSTN) in a public switched telephone network (PSTN) to perform interworking between an internet user and an individual terminal. It relates to how to send and receive mail.

In general, when transmitting and receiving e-mails using the Internet, which is a data communication, text is mainly performed. However, a sound card or the like may be used while incorporating multimedia technology into a personal computer (PC). Voice was transmitted through e-mail, and the received voice could be received using a PC or a workstation and played back the received voice e-mail. In this case, the technology is an operation performed only in the data communication network.

Then, in the conventional structure for transmitting and receiving voice e-mail, as shown in Figure 1, voice e-mail terminals (11, 12) such as a PC, workstation, and voice e-mail server (13, 14) And the Internet network 15 and the PSDN 16.

The operation of the voice e-mail transmission / reception structure configured as described above will be described. The operation of the voice e-mail from the A side to the B side will be described.

The voice card to be transmitted is recorded using the sound card installed in the voice e-mail terminal 11 of the A side, and the recorded file is transmitted to the E-mail address of the B side of the other party. At this time, between the voice e-mail server 13 connected with the voice e-mail terminal 11 on the A side and the voice e-mail server 14 connected with the voice e-mail terminal 12 on the B side. By using the PSDN (16) in the transmission.

Accordingly, the B side receiving the recorded file confirms that the file has arrived through the voice e-mail terminal 12 and receives the received file, and after encoding the received file with voice, The encoded voice is reproduced and listened using a tool using a sound card.

In other words, if a PC or workstation from side A sends voice e-mail to side B, only those PCs or workstations capable of accepting the same series of operating systems or data communications on that side B will also receive the voice e-mail. It can receive and listen, that is, the PC or workstation must have a built-in device capable of processing voice, and can listen to voice e-mails directly through the device.

As described above, in the case of Internet e-mail using a data communication network, transmission and reception can be performed only between terminals linked to the same data network.

By the way, the PCS (Personal Communication Service) and the mobile terminal is now common, and the urgent message delivery is possible even when moving, and the use of e-mail is frequently used. In the case of receiving the e-mail in the prior art, There was an inconvenient connection only when using a PC or a workstation capable of receiving e-mail. In addition, even when the voice is converted to an e-mail transmission, there is an inconvenience that must use the PC or workstation.

In order to solve the problems described above, the present invention can reduce the transmission delay of the e-mail by interworking by accepting the Internet voice e-mail in the PSTN that can be serviced only by using the PSDN It is also possible to send and receive Internet voice e-mail using a telephone, PCS, mobile phone, and the like.

In other words, when the mail server receives the voice e-mail using the Internet, the present invention delivers the Internet voice e-mail to AIN-IP, VMS, etc., rather than a PC or a workstation, and sends a simple telephone, PCS, mobile phone, or the like. By enabling the user to check the Internet voice e-mail, the user's convenience is facilitated by interworking with the rapidly increasing Internet users and individual phones, PCS, mobile phones, etc. There is this.

Voice e-mail transmission and reception method of the present invention for achieving the above object is to receive a voice e-mail from the Internet network in the e-mail server to notify the PC or workstation after receiving the voice e-mail Checking whether there is a request or a search request; Confirming that there is no reception request or search request for a predetermined time, and requesting a search for whether the voice e-mail is available to a recipient by AIN-IP or VMS; Retrieving the subscriber's terminal status after identifying the subscriber number in the voice e-mail recipient profile; Confirming that the receiver is a subscriber of the AIN-IP or the VMS and the terminal is in a usable state, and transmitting the voice e-mail to the server of the AIN-IP or the local server of the VMS; Notifying the receiver terminal of the reception of the Internet voice e-mail in the AIN-IP or the VMS; Performing an authentication procedure by accessing an AIN-IP or a VMS by origination of a receiver terminal; And converting the Internet voice e-mail into a voice compression method to listen to the receiver.

Alternatively, the voice e-mail transmitting and receiving method of the present invention comprises the steps of: storing and deleting the voice e-mail upon request for storing and deleting the voice e-mail listened to by the receiver; The method may further include storing the response content when the receiver requests a response and delivering the message to the sender of the voice e-mail. Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

The overall structure for transmitting and receiving voice e-mail according to an embodiment of the present invention additionally utilizes an interworking part of an e-mail server and a VMS, AIN-IP, etc. in a conventional configuration. As shown in FIG. 2, the AIN-IP or VMS 30 is interworked with terminals such as telephones, mobile phones, and public phones available in the PSTN, and the corresponding AIN-IP 30 is configured as the PSDN 20. It works in conjunction with an e-mail server with Transmission Control Protocol / Internet Protocol (TCP / IP) and with Post Office Protocol (POP).

Here, the AIN-IP or VMS 30 accepts subscriber information by itself or as a local server, receives a voice e-mail for the subscriber from the e-mail server to the POP, Voice compression method for verifying whether the user can use the e-mail according to the request of the e-mail server, decode the encoded information of the voice e-mail when using the Internet and use it in each system To perform the conversion.

In addition, the e-mail server of the PSDN 20 primarily informs the terminal of the mail receiver that the mail has been received. If there is no reception or retrieval of the mail after a predetermined time elapses, the recipient of the mail uses the telephone. The AIN-IP or VMS 30 is requested to verify whether the user can use e-mail as a terminal, and if the subscriber is verified at the AIN-IP or VMS 30, the e-mail is received at the subscriber's terminal. It tells you that In this case, the form of the corresponding e-mail is additionally informed that the voice is not text, so that the voice terminal can be listened to using the telephone terminal.

In addition, look at the configuration of the AIN-IP or VMS 30 in more detail, the AIN-IP consists of an open system (Open System) is controlled by the SCP that controls the service in the intelligent network and the VMS is CMS It is controlled by the CMS with an open system server called (Conference Mixer). Since the AIN-IP and the VMS are made in a similar manner, only the corresponding AIN-IP will be described.

The AIN-IP has a database that stores information and profiles of subscribers, controls and configures service-related matters. When using SUN, it uses a Solaris-based operating system and manages HP servers. Even when used, since the Unix-based OS is used, the interworking with the e-mail server is performed using TCP / IP.

As shown in FIG. 3, the AIN-IP includes a SRMP 31, a LAN router 32, and a general operating system (OS), which are equipped with an HME (100BaseT LAN Interface Card or Apparatus). And a plurality of SRUs 34-1 to 34-4 that match the subscriber channel and collect voice, record, transmit, and DTMF. Here, the number seven using the time slot of the E1 trunk is used for interworking between the SCP and the SRS 33, and the rest is connected to the subscriber through the E1 interworking with the SSP, and the SRS 33 and the SRU 34-1 to 34-. 4) is connected by a pure bearer E1 that does not use a signaling method.

However, in FIG. 3, the part interworking with the mobile terminal is not directly interworked, and the configuration of the IP (Intelligent Peripheral), the e-mail server, and the SCP mobile terminal is shown in FIG. 4 through e-mail via TCP / IP. SSPs 42-1 and 42-2, which are connected to servers and connected to the number seven, respectively, and the corresponding SCPs 41 and IP 43 through E1. And a Mobile Switching Center (MSC) 44 connected to the corresponding SSP 42-1, a Home Locator Register (HLR) 45 for determining the location of the subscriber station, and a plurality of devices for transmitting and receiving data with the subscriber station. It consists of BS (Base Station) 46-1 ~ 46-N. The IP 43 plays a role of providing a special resource in the intelligent network.

Looking at the operation of voice e-mail transmission and reception according to an embodiment of the present invention with reference to Figs. 3 and 4, when the voice e-mail is received in the e-mail server 21 from the Internet network corresponding e-mail server ( In 21), it is received after confirming the mail ID.

At this time, if the subscriber notifies the reception of the voice e-mail to the desktop computer or the notebook, but does not receive the voice e-mail after a certain time, for example, 30 minutes to When the time of about 1 hour has elapsed, the search for the voice e-mail received by the e-mail server 21 using the assigned IP address of SCP 41 is performed by the corresponding SCP 41. .

The SCP 41 finds that the IP 43 can be used based on the name of the subscriber corresponding to the mail ID and the information entered in the subscriber profile, that is, the SCP 41 is configured as an open system. Since the profile information of the subscriber is inquired using TCP / IP, and the receiving function of the voice e-mail is set in the subscriber profile, the SCP 41 is informed that the voice e-mail has been received. 41) connects to the subscriber's terminal using the information registered in the subscriber profile.

Accordingly, the voice e-mail received through the IP 43 is transmitted by FTP (File Transfer Protocol), and when the transmission is completed, the mail 41 is requested to the SCP 41. At this time, the SCP 41 confirms the identity of the subscriber using the subscriber profile and then converts the corresponding voice e-mail using the SRMP 31, SRUs 34-1 to 34-4 of the IP 43, and the like. After the process is heard to the terminal of the subscriber, if the operation is performed normally informs the execution result to the e-mail server (21). Here, it is necessary to convert the corresponding voice e-mail in a manner that the SRUs 34-1 to 34-4 can use. This is a simple voice compression algorithm, which is used by the corresponding SRUs 34-1 to 34-4. Converting a waved file in a manner may also be performed on the corresponding SRMP 31 and enabled CPU boards of the main unit of the corresponding SRUs 34-1 to 34-4 (e.g. 5VT, 8VT, etc.). Is also possible. In addition, when converting a wave file into ADPCM (Adaptive Differential Pulse Code Modulation) and a compressed wave file into ADPCM, a separate algorithm is performed according to the load of the corresponding control device CPU.

Then, the operation of informing the subscriber terminal (when wireless) of the reception of the voice e-mail is performed by determining the location of the subscriber terminal to the HLR 45 through the interworking MSC 44. N) informs the reception of voice e-mail. In addition, when the subscriber listens to the corresponding voice e-mail and immediately sends a response mail, the subscriber assigns a unique identification number to each mail, which can be used to classify each mail. The reverse transmission is performed by the classified mail identification number, and the operation is performed by the IP 43 after converting the mail received by the ADPCM into a wave form and then passing it through the email server 21. .

In addition, the outgoing operation may be connected regardless of whether the subscriber is wired or wireless (i.e., PCS, mobile phone). Verify your presence using Play Announcement (PA).

For example, as a broadcast comment 'Are you ***? We will verify your password to verify your identity. Please enter the password you have set. 'The subscriber will enter a digit of' 1234 '. After checking the information collected by the IP 43, the SCP 41 broadcasts the received voice e-mail using the IP 43. At this time, the IP 43 is received by the SRMP 31 of the IP 43 when the e-mail server 21 determines that the result of the inquiry through the SCP 41 is the recipient of the voice e-mail. The voice e-mail is delivered using a file transfer protocol, and when the delivery of the voice e-mail is completed, the IP 43 is informed that the delivery is completed. For example, the broadcast comment says 'Your mail from *** is ~'.

Next, a voice e-mail transmission and reception method according to an embodiment of the present invention will be described with reference to the flowchart of FIG. 5.

When a voice-encoded e-mail is received by a user who can receive e-mail over the Internet, i.e., a voice e-mail is received at the e-mail server from the Internet network (step S1), shown in FIG. Notify the PC or workstation on side B that voice e-mail has been received. At this time, each PC or workstation is running a pop-up program that notifies when a voice e-mail is received.

However, the PC or workstation used by the user may not be able to listen to the voice-encoded e-mail, or the user may be difficult to receive the voice e-mail because the user is moving to another location. As it may occur, the e-mail server notifies the voice e-mail recipient's PC or workstation terminal (step S2) and checks whether there is a request to receive or retrieve the voice e-mail while waiting a predetermined time. (Step S3). Here, the predetermined time is allocated to the e-mail server as a grace time of about 1 to 2 hours, for example, and the e-mail server has a push service function so that the push result can be known. That is, whether the recipient has processed the voice e-mail.

Therefore, even if the predetermined time elapses in the third step S3, if there is a request for receiving or searching for the voice e-mail, the voice is transmitted through the PC or workstation terminal of the voice e-mail receiver as in the conventional operation. The e-mail is received and listened to (step S4). However, if it is confirmed in the third step (S3) that there is no request or a search request for the voice e-mail even after the predetermined time has elapsed (step S5), the receiver is connected to AIN-IP, VMS, etc., which can be interworked. A search is requested as to whether the voice e-mail is available (step S6). Here, the e-mail server plays a role of assigning a profile associated with the subscriber's e-mail address. The profile includes a password related to the subscriber's mail account, a contact number, etc., and the contact moves a PCS or the like. The terminal number is assigned. In addition, the e-mail server has a simple data table or database using the index function of the mobile terminal, and assigns the mobile terminal to each server according to the assigned mobile terminal number. For example, '011-111-1111' Assign it to server 'A' and assign '016-111-1111' to server 'B'.

Then, after identifying the subscriber number in the voice e-mail recipient profile (step S7), the server can query the server that can query the state of the terminal (step S8). For example, by querying each representative server of A and B, the server A finds the presence and the current state of the subscriber by using the HLR, etc., because the server is its own terminal.

Accordingly, if the mobile terminal of the subscriber is available as a result of the inquiry in the eighth step S8 and the subscriber is a user such as AIN-IP or VMS, the received voice e-mail is sent to the server or VMS of the AIN-IP. Deliver to the local server of (step S9).

At this time, the method of delivering the received voice e-mail to the server of the AIN-IP or the local server of the VMS may use FTP or POP, and the e-mail server may be operated by a general Unix-like operation. Use the framework. In addition, SRMP 31 shown in Fig. 3 is an HP-based server, and in the case of VMS, a UNIX server called CMS is used.

Accordingly, the AIN-IP, VMS, etc. inform the subscriber terminal that the received voice e-mail has been received from the Internet terminal (step S10). The method of notifying that the Internet voice e-mail has been received may be used in various ways. In FIG. 4, the mobile terminal uses the HLR 45 and the wired terminal uses the SCP 41. The HLR 45 may inform the mobile station subscriber's location and status using the BSs 46-1 to 46-N associated with the MSC 44.

Therefore, when notifying the terminal of the user that the Internet voice e-mail has been received, the user is connected to the AIN-IP, VMS, etc. (step S11). That is, in FIG. 4, the subscriber of the mobile terminal sends a subscriber VMS, IP, etc. to perform the access.

After being connected in the tenth step S10, an appropriate authentication procedure is performed (step S12), and the voice e-mail can be listened to. In FIG. 4, the MSC 44 connects to the IP 43 via the SSP 42-1 through the BSs 46-1 to 46 -N, and the VMS in the case of the mobile terminal is directly connected to the MSC 44. May be connected.

At this time, the AIN-IP, VMS, etc. converts the voice e-mail over the Internet into a voice compression method using the system and plays the voice (step S13). In FIG. 3, the SRMP 31 converts the message received from the Internet e-mail server into the form of ADPCM used by AIN-IP and VMS when the message is in the form of a wave used by a PC.

Accordingly, when the user processes and responds to the voice e-mail in a request method after listening to the Internet voice e-mail, the reverse process of the above-described operation is performed. In other words, when the subscriber requests the storage of the voice e-mail listened to, the subscriber stores the voice e-mail. In addition, in response to the response, the response is stored, and the SRMP 31 delivers the message to the sender of the mail in the same function and operation as the e-mail server.

Alternatively, systems that attempt to interoperate PSDN and PSTN in a manner called Universal Message Service (UMS) in a similar manner as described above may be performed in the field of computer telephone interface (CTI), which is rapidly increasing Internet voice email. The proposed method and the interworking method are proposed, and in the case of the UMS, it is proposed to accept various things in the user's mail box, and to accept the Internet voice e-mail, TTS (Telecommunication Transport Service), E- E-mail inquiry, voice recognition, fax, etc. may also be proposed.

As described above, according to the present invention, the Internet voice e-mail that can be serviced only by using the PSDN is accommodated in the PSTN to perform interworking, thereby reducing the delay of e-mail and providing a simple call, a PCS, a mobile phone, and the like. Internet voice e-mail can be transmitted and received, and user's convenience can be achieved by interworking with rapidly increasing Internet users and individualized PCS and mobile phones.
